Using Brain Science Theory to Analyze the Unity between Language Input and Output: Methodology Improvement Substantiation Використання теорії системної роботи мозку для аналізу єдності між мовними конструкціями введення/виведення: обґрунтування поліпшення методології

Introduction. Based on the brain science theory of “how people learn” and in order to modernize the methodology of psycholinguistic research, this research used documentary analysis and addressed the standpoint that the 4MAT Teaching and Learning Model can be subsumed into or superimposed on the Kirkpatrick Four-Level Evaluation Model, and vice versa. Meanwhile, the phase of language input and output is analyzed on the basis of the two Models above. In the end, some implications arise so as to provide reference for prospective researchers and practitioners in psycholinguistics. 
The aim of the study. The 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model are both widely applied, so a deliberate literature review to clarify the integration and the unity between them is conducted that expects to make some theoretical references inspired by the unity available to a wide range of linguistic teaching design and learning performance evaluation. 
The authors argue that the references interconnect teaching design and learning performance evaluation in light of language input and output and therefore help linguistic teachers/trainers with a whole and valid scheme at the very beginning of student learning, and this is the unity that also corresponds to Kirkpatrick & Kirkpatrick’s standpoint: “The end is the beginning”. 
Research methods. The study was conducted using the semantic differential scaling and the method of documentary analysis. 
Results. A combination of brain science theory and Fractal Information Theory has verified initially how the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model subsume and superimpose in terms of the theoretical framework, i.e., the unity between a teaching theory and a learning performance evaluation theory. Such integration not only originates from the inherent unity verified by a thoughtful literature review but also receives theoretical support from interdisciplinary studies. Meanwhile, this integration is intertwined with language input and output in a psycholinguistic/neurolinguistic manner. 
Conclusions. A primary investigation using brain science theory and other theories to analyze the integration between the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model shows the unity between both models. This investigation led to achieving the purpose of the study: modernizing the methodology of psycholinguistic research. With implementing the components/stages of language input and output as this article proposed, it is expected to be promising in extending and applying both models theoretically and practically in linguistics and other relevant areas in the future. As it comes to studies, it is recommended that the two Models be connected to analyze more teaching models and/or learning performance evaluation models for unity, inquire performance evaluation in collaborations with scenarios in practice, or even associate other disciplines under the implementation of Fractal Information Theory. A possible suggestion for psycholinguistic researchers is to design curricular and lessons based on the Unified Models (Figure 1 & 2) proposed in this study and evaluate instructional efficacy and student learning performance. Another potential research direction is to use each quadrant of the Unified Models and analyze related components in more specific language input and output phases: listening, reading, speaking, writing, and even smaller components in the four types of language skills. As it comes to practice, especially in psycholinguistics and/or other relevant disciplines, the key to apply the two target Models simultaneously depends on how to regulate respective quadrants/levels pro rata as well as the wholeness between them to simultaneously achieve “dynamic equilibrium” in the 4MAT Teaching and Learning Model and “The end is the beginning” in the Kirkpatrick Four-Level Evaluation Model.


Introduction
To achieve the purpose of the study, this article will incorporate the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model with the phase of language input and output into two Unifi ed Models so as to modernize the methodology of psycholinguistic research.
Following the 4MAT System which classifi es and defi nes various learning styles of learners by blending interdisciplinary theories of brain science, neurology, education, administration and psychology (Lin, 2016a;McCarthy, 1980McCarthy, , 2000, the 4MAT Teaching and Learning Model advocates the emotional, mental and physical aspects as the fundamental components of teaching and learning through fractal theory along with the information processing paths in the brain (Caviness, 2007), and employs the concept of how people learn to enhance learning performance in the course of instruction (Czyż & Svyrydenko, 2019;Kalat, 2013;Lin, 2013Lin, , 2016aSousa, 2011a;Watson et al., 2019;Wolfe, 2010;Zull, 2002). The Kirkpatrick Four-Level Evaluation Model -Reaction (Level 1), Learning (Level 2), Behavior (Level 3), and Results (Level 4) is the most acknowledgeable scale to assess performance after learning/training given to students/trainees which advocates that every and each teacher/trainer with effi cacy should evaluate all of the activities in the course of teaching/training for effective learning performance evaluation (Kirkpatrick & Kirkpatrick, 2006;Kirkpatrick & Kirkpatrick, 2011, 2019Sim, 2017).
Firstly, the study deliberately focuses on the two theories, the Caviness 4MAT Teaching and Learning Model (Caviness, 2007) and the Kirkpatrick Four-Level Evaluation Model (Kirkpatrick & Kirkpatrick, 2006;Kirkpatrick & Kirkpatrick, 2011, 2019, and elaborates their annotations, with providing a defi nition of language input and output in this article. Secondly, the structural integration between the two Models and «language input and output» (Sousa, 2011b) is investigated. Thirdly, a combination of Fractal Information Theory (FIT) (Agrawal et al., 2018) and brain science theory explores how they inter-subsume (for example (Fatkhutdinov & Bazaluk, 2018)). Hopefully, steps 1 through 3 above interconnect teaching design and learning performance evaluation in light of language input and output and therefore help linguistic teachers/ trainers with a whole and valid scheme at the very beginning of student learning, and this is the unity that also corresponds to Kirkpatrick & Kirkpatrick's standpoint: «The end is the Beginning» (Kirkpatrick & Kirkpatrick, 2011: 60). The 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model are both widely applied, so a deliberate literature review to clarify the integration and the unity between them is conducted that expects to make some theoretical references inspired by the unity available to a wide range of linguistic teaching design and learning performance evaluation (Chen et al., 2012;Hsiao, 2010;Huang & Hsieh, 2011;Reio et al., 2017;Sim, 2017;United States, 2008).

Defi nitions of the Models and Theoretical Frameworks
In order to modernize the methodology of psycholinguistic research, the two target models implemented for analysis in this article are fi rst introduced in this section before defi ning language input and output, followed by a description of Fractal Information Theory (FIT) used as the carrier of the two target models and the phase of language input and output.

4MAT Teaching and Learning Model
The primary theoretical source of the 4MAT Teaching and Learning Model is the 4MAT System (Caviness, 2007;Lin, 2013Lin, , 2016aMcCarthy, 2000). On the basis of Kolb's concepts of the structure of learning, i.e., his Experiential Learning Model (Watson et al., 2019), the McCarthy 4MAT System employs the concepts of plane geometry to classify how one learns into 4 quadrants: Quadrant one (Q1) as «the highly imaginative student who favors feeling and refl ecting,» Quadrant two (Q2) as «the analytic student who favors refl ecting and thinking,» Quadrant three (Q3) as «the common-sense learner who favors thinking and doing» and Quadrant four (Q4) as «the dynamic learner who favors creating and acting» (Lin, 2013: 32;Lin, 2016a: 5;McCarthy, 1997: 46-48;McCarthy, 2000).
A combination of the McCarthy 4MAT System and the clockwise information processing direction in the brain (Zull, 2002) made by Caviness (2007) contributing to her teaching/learning steps of Q1-Q4 in the 4MAT Teaching and Learning Model expects to give teachers of any fi eld a foundation of brain science theory with regard to instructional activity design (Lin, 2016a). Q1 is the emotional aspect of learning that corresponds to the sensory integration zone (starting from the somatosensory cortex) in charge of information processing in the cerebral cortex; Q2 is the mental aspect of learning that corresponds to the conceptual integration zone (mainly the prefrontal cortex) in charge of information processing in the cerebral cortex; Q3 is the physical aspect of learning that corresponds to the motor integration zone (the motor cortex sends commands to the body) in charge of information processing in the cerebral cortex (Caviness, 2001(Caviness, , 2007Lin, 2013Lin, , 2016aZull, 2002). Q4 is service learning that contributes learning results to others and is the end fruit of the whole brain (Caviness, 2007;Lin, 2013Lin, , 2016a. The 4 quadrants are stated as follows: Quadrant 1: the Emotional aspect values the connection between what has been known and what is to be known for a learner with the importance of the incoming information explicitly defi ned, i.e., the meaning of that learning (Caviness, 2007). According to the 4MAT Teaching and Learning Models by Caviness (2007) and Lin (2013), the latter of whom names Q1 the Affective aspect, the authors also name Q1 the Affective aspect, or Affect (Lin, 2013(Lin, , 2016a.
Quadrant 2: the Mental aspect values the content of learning. In such phase, it is common for a teacher to teach information in a oneway manner (Caviness, 2007). Following the Lin 4MAT Teaching and Learning Model (2013), the authors also name Q2 the Cognitive aspect, or Cognition (Lin, 2013(Lin, , 2016a.
Quadrant 3: the Physical aspect highlights drills of skills and explicit performance of what is learnt in reality (Caviness, 2007). In accordance with the Lin 4MAT Teaching and Learning Model (2013), the authors also name Q3 the Behavioral aspect, or Behavior (Lin, 2013(Lin, , 2016a. The learning aspects subsumed by Q1, Q2 and Q3 are supported by other theories that agree to the affective, cognitive and skill-based types of learning results. As it comes to the discipline of organizational communication, the Inventory of Change in Organizational Culture classifi es reaction to change into the affective, cognitive and behavioral respects (Driskill, 2019).
Quadrant 4: the Service Learning aspect in the Caviness 4MAT Teaching and Learning Model pinpoints how a learner conducts personal extension and application of what is learnt, conveys what has been learnt to others, and contributes to others (Caviness, 2007). This is named by Caviness «Disequilibrium» and by Lin «Balance & Disequilibration» equivalent to «dynamic equilibrium» or «disequilibrated equilibrium,» respectively (Lin, 2013(Lin, , 2016a.

Kirkpatrick Four-Level Evaluation Model
The Kirkpatrick Four-Level Evaluation Model published by Kirkpatrick in 1959 with Levels 1-4, Level 1: Reaction, Level 2: Learning, Level 3: Behavior, and Level 4: Results, is the most adopted evaluation model for the offi cial training institutions acknowledged offi cially by the United States (United States, 2008) while some paper pinpoints its application to the education discipline as well (Reio et al., 2017).
Each level of the Kirkpatrick Four-Level Evaluation Model interlinks closely where each has its unique impact on the next inevitably (Hsiao, 2010). The authors annotate Levels 1-4 of the Kirkpatrick Four-Level Evaluation Model specifi cally as follows (Kirkpatrick & Kirkpatrick, 2006;Kirkpatrick & Kirkpatrick, 2011, 2019: Level 1: Reaction Reaction refers to how a learner perceives the course attended in person, i.e., the personal satisfaction or preference level. The evaluation core of Level 1 covers multiple respects including but not limited to the overall curriculum structure of teaching/training, the quality of the teacher, the anchors (goal anchoring), the theme arrangement, the content setting, the timeline planning, the instructional skills/ techniques, the teaching hardware (instruments/materials), the ambient hardware (environment/equipment), administration/management and miscellaneous backup (administrative support); however, in this phase, merely how a learner senses learning is inspected but how the content is comprehended or mastered remains unevaluated (Chen et al., 2012;Huang & Hsieh, 2011).
Level 2: Learning Level 2 essentially evaluates how a student or a trainee performs in terms of the affective, cognitive and skill-based aspects where the affective results include attitude and motivation, the cognitive results include knowledge and strategies and the skill-based results include technique and operation; however, in this phase, merely how a learner performs after learning is inspected but how the content learnt is used remains unevaluated (Chen et al., 2012).

Level 3: Behavior
In accordance with Huang & Hsieh (2011), Level 3 evaluates how a student/trainee enhances any competence or behavior materially after attending the course with the following questions reviewed:

«Can their transfer of learning appear out of the evaluated teaching process? Can their attitude, knowledge or skills acquired in this Level be used in real life? Can their behavior be improved out of the evaluated learning process?».
It requires adequate time given to a learner for behavioral change (Huang & Hsieh, 2011;Kirkpatrick & Kirkpatrick, 2006); however, in this phase, merely how a learner performs personally after learning is inspected but how individuals perform in non-individual circumstances (organizations/groups) remains unevaluated and this is to be evaluated in Level 4.

Level 4: Results
Level 4 evaluates the following questions: «Can a learner acquire the attitude, skills and knowledge (Level 2) out of the learning process? Can Level 2 result in behavioral change (Level 3)? Can a learner perform for the organization (not for oneself)?» (Chen et al., 2012) According to Hsiao (2010), a positive correlation between each evaluation level and its complexity is proven, so the higher the evaluation level is, the more complexity it has. Additionally, as aforementioned in Level 3, it requires adequate time given to a learner for signifi cant performance (Chen et al., 2012).

Fractal Information Theory (FIT) as the Carrier of How the 4MAT Teaching and Learning Model, the Kirkpatrick Four-Level Evaluation Model, and Language Input and Output Inter-Subsume
Fractal Information Theory (FIT) has the features as follows fi tted to be the carrier to how the 4MAT Teaching and Learning Model, the Kirkpatrick Four-Level Evaluation Model, and language input and output inter-subsume (Agrawal et al., 2018;Caviness, 2007;McCarthy & O'Neill-Blackwell, 2007;Sousa, 2011b). A fractal, geometrically a subset of a topology similar or identical to the original, appears the same even at different levels. Its conception means the unlimited replication or extension of self-similarity. As for its application, it can connect theories or make levels with similarities or identical conceptions correspond, subsume or superimpose (Agrawal et al., 2018;Caviness, 2001Caviness, , 2007Lin, 2016a). Caviness (2001Caviness ( , 2007 employs Fractal Information Theory to relate different human learning levels. With a triangle as the architecture for the components to inter-subsume, Levels 1-3 of Learning, Parts 1-3 in Neuron, Parts 1-3 in Brain, and Parts 1-3 of Mankind are interimposed to form a successive expanding multi-triad. The aspects of the Caviness triad of learning are specifi ed below (Caviness, 2007;Lin, 2013Lin, , 2016aKalat, 2013;Sousa, 2011a;Wolfe, 2010;Zull, 2002): (a) Affective/Emotional: Dendrite in Neuron (the sensory integration zone at the neuron level) in charge of receiving information, Limbic system in Brain (in charge of emotions in the sensory integration zone at the brain level) and Heart of Mankind. (b) Cognitive/Mental: Soma in Neuron (the conceptual integration zone at the neuron level) in charge of conveying information or not, Cortex in Brain (the conceptual integration zone at the brain level), and Brain of Mankind. (c) Behavioral/Physical: Axon in Neuron (the motor integration zone at the neuron level), Brain Stem in Brain (the motor integration zone at the brain level), and Body of Mankind.
Caviness (2007) relates the key components in Mankind, Brain and Neuron that interconnect in terms of their meanings: Heart (Affect), Brain (Cognition) and Body (Behavior) in Mankind; Limbic System (Affect), Cortex (Cognition) and Brain Stem (Behavior) in Brain; and Dendrite (Affect), Soma (Cognition) and Axon (Behavior) in Neuron (Lin, 2016a). As aforementioned in the nature of fractals, the fractal conception can be applicable for Mankind, Brain and Neuron as well: Mankind, Brain and Neuron identical to fractals appear the same even at different levels (Caviness, 2001(Caviness, , 2007Lin, 2013Lin, , 2016a.
With Neuron, Brain and Mankind that conceptually interconnect and correspond, it is suitable to employ Fractal Information Theory as the carrier to explicate how the 4MAT Teaching and Learning Model, the Kirkpatrick Four-Level Evaluation Model, and language input and output mutually inter-subsume and inter-superimpose is adequate: (1) Affect in the 4MAT Teaching and Learning Model inter-corresponds to Reaction in the Kirkpatrick Four-Level Evaluation Model and to the initial and major stages of language input (affective/sensory input, inclusive of listening and reading) processing before concept formation, (2) Cognition in the 4MAT Teaching and Learning Model intercorresponds to Learning in the Kirkpatrick Four-Level Evaluation Model and to mental concept formation of language input processing, which prepares to output language (cognitive process), and (3) Behavior in the 4MAT Teaching and Learning Model inter-corresponds to Behavior in the Kirkpatrick Four-Level Evaluation Model and to language output: speaking and writing (behavioral skills in language performance). Consequently, the authors utilize Fractal Information Theory as the carrier of how the 4MAT Teaching and Learning Model, the Kirkpatrick Four-Level Evaluation Model, and language input and output intersubsume in this study (Lin, 2016b;McCarthy & O'Neill-Blackwell, 2007;Sousa, 2011b). There are four components in the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model (4 quadrants and 4 levels), so the authors adopt a quadriad to make them subsume and superimpose using brain science theory and Fractal Information Theory and manages to make each quadrant in the 4MAT Teaching and Learning Model connect with and correspond to each level in the Kirkpatrick Four-Level Evaluation Mode. Meanwhile, the concepts of language input and language output can superimposed on the two Models as all of them inter-subsume. The procedure is as follows (Caviness, 2007, Lin, 2013, 2016a, 2016bMcCarthy & O'Neill-Blackwell, 2007;Sousa, 2011b (Caviness, 2007;Hsiao, 2010: 4).

Using Brain Science Theory and Fractal Information Theory to Analyze How the 4MAT Teaching and Learning Model, the Kirkpatrick Four-Level Evaluation Model, and Language Input and
With regard to learning in general, sensory (auditory/visual) input drives emotion (Caviness, 2001(Caviness, , 2007Kalat, 2013, Lin, 2013, and therefore the initial and major stages of language input processing (before concept formation) can be categorized into Quadrant 1/Level l (Sousa, 2011b). Delving deeper, «Emotion drives attention and attention drives learning» (Sylwester, 1995: 72). This corresponds to Affect valued by Q1 in the 4MAT Teaching and Learning Model. An attentive learner results from curiosity aroused by the learning process (Caviness, 2007), agreed by Lin (2013)  Model (Caviness, 2007, p. 25). The three-aspected components of teaching and learning above are honored and can be applied in the process of language teaching and learning as in language learning mental concept formation is connected to the affective, cognitive and skill-based aspects as well (Sousa, 2011b (Chen et al., 2012;Hsiao, 2010). Implementation includes action plans and competency testing that identify transfer of learning and this corresponds to the emphasis of Skill-based in Q3 in compliance with the question asked by Q3 (How?) in the Caviness 4MAT Teaching and Learning Model (Caviness, 2007, p. 25). The skill-based emphasis can be directly linked to teaching and/ or learning speaking and writing (language output) as behavioral skills in language education/performance. It requires the following 4 Terms that exist simultaneously for behavioral change by learning (Kirkpatrick & Kirkpatrick, 2006): Term 1, a learner is in the right mood; Term 2, a learner is fond of change; Term 3, a learner is inspired; and Term 4, a learner is aware of what to do and how to do. Given that, how Level 3 Behavior in the Kirkpatrick Four-Level Evaluation Model corresponds to Q1-Q3 in the 4MAT Teaching and Learning Model is stated as follows: Term 1 corresponds to Q1, i.e., the ambient setting that is good enough and assures positive affection, as is connected to sensory input in language teaching and learning; Term 2 corresponds to intrinsic motivation valued by Q1; Terms 3 corresponds to extrinsic motivation valued by Q2 & Q3 and returns to affect and intrinsic motivation in Q1; and Term 4 corresponds to «What?», which is connected to concept formation in language teaching and learning, and «How?», which is connected to language output in language teaching and learning, subsumed by Q2 & Q3, respectively (Caviness, 2007: 25;Kirkpatrick & Kirkpatrick, 2006;Lin, 2013Lin, , 2016a (Caviness, 2007) corresponds to Level 4 Results in the Kirkpatrick Four-Level Evaluation Model: A person performs for a group (organization), and to the whole integration of language input and output in language education (Kirkpatrick & Kirkpatrick, 2011, 2019Lin, 2016aLin, , 2016bMcCarthy & O'Neill-Blackwell, 2007;Sousa, 2011b). Evaluation of Results includes the methods of questionnaires, experimental comparison and pretest and posttest comparison that examine personal performance for organizations/ groups (Chen et al., 2012). Service Learning is specifi cally elaborated: «as the learner moves focus away from intake for personal improvement and toward output for the benefi t of others, mutual benefi t occurs -among teacher, student, and class members» (Caviness, 2007: 26).
Caviness also indicates that Q4 in the 4MAT Teaching and Learning Model receives the least attention during learning in particular. Within all Levels in the Kirkpatrick Four-Level Evaluation Model, Level 4 Results is the most challenging to attain (Hsiao, 2010). The concept that

«Each Level in the Kirkpatrick Four-Level Evaluation
Model is sequential and each impacts the next» (Hsiao, 2010: 3) is identical to brain science theory in the 4MAT Teaching and Learning Model since the sequential order of Q1-Q4 equals to the information processing procedure in the brain and thus refers to priority intrinsically given as it comes to time and inherent logic. The processing of language input and output follows the same manner (Caviness, 2007;Zull 2002;Sousa, 2011b).
The fi gure of how the 4MAT Teaching and Learning Model, the Kirkpatrick Four-Level Evaluation Model and Language Input and Output correspond with Fractal Information Theory as the carrier is  (Agrawal et al., 2018;Caviness, 2001;Caviness, 2007: 25;Gazzaniga et al., 2002;Kirkpatrick & Kirkpatrick, 2006;Kirkpatrick & Kirkpatrick, 2011, 2019Lin, 2013: 33;Lin, 2016a: 10;Lin, 2016b;McCarthy, 2000;McCarthy & O'Neill-Blackwell, 2007;Sousa, 2011aSousa, , 2011bZull, 2002) 2. Application of Dynamic Equilibrium (Disequilibrated Equilibrium) to the 4MAT Teaching and Learning Model, the Kirkpatrick Four-Level Evaluation Model, and Language Input and Output Effective teaching requires balance between 4 quadrants in the 4MAT Teaching and Learning Model and intrinsic and extrinsic motivation simultaneously (Caviness, 2007). That is, each matters the same (Lin, 2016a). A combination of such concept and the correlation between the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model shows that equilibrated Levels 1-4 in the Kirkpatrick Four-Level Evaluation Model are also required and each matters the same. Similarly, the four quadrants of language input and output shown in Figure 1 can be considered and implemented in this manner. Caviness (2007) points out that a creature needs disequilibrium or remains non-stagnated for sustainability. Glasser (1986) identifi es the co-existence pro rata of and the interdependence across «feeling» (affect), «thought» (cognition), «action» (behavior), and «physiological activity» for mankind, which forms our wholeness. This is dynamic equilibrium in the 4MAT Teaching and Learning Model (Caviness, 2007;Glasser, 1986: 45;Lin, 2013;Lin, 2016a: 15).
The aforementioned perspective of Glasser (1986) corresponds to Q1-Q3 integrated as Q4 in the 4MAT Teaching and Learning Model (Caviness, 2007). Levels 1-3 eventually lead to Level 4 in the Kirkpatrick Four-Level Evaluation Model as well -and so are the 4 language input and output stages (Chen et al., 2012;Sousa, 2011b). In the 4MAT Teaching and Learning Model, Caviness pinpoints that Q4 values dynamic equilibrium across the components in Q1-Q3 (Caviness, 2007). Level 4 Results in the Kirkpatrick Four-Level Evaluation Model also covers the components in Levels 1-3 pro rata: Any person performs for any organization with a learning/training activity given specifi cally must undergo Level 1: perception of such activity, Level 2: enhancement of the attitude, knowledge or skills due to such procedure, and Level 3: personal behavioral change by such activity (Chen et al., 2012). As identifi ed by Kirkpatrick and Kirkpatrick (2006, 2019, every and each linguistic training/learning activity requires the design, exercise and performance evaluation aspects that interlink to and/or interconnect with Levels 1-4 in the Kirkpatrick Four-Level Evaluation Model. This is also a presentation of Fractal Information Theory and Glasser's perspective: Each learning activity or any teaching procedure covers tacit conceptions of the Kirkpatrick Four-Level Evaluation Model a.k.a. replication of a self-similar quadriad (Caviness, 2007;Glasser, 1986;Lin, 2013Lin, , 2016aLin, , 2016bMcCarthy & O'Neill-Blackwell, 2007). White (1903) defi nes education as «True education … is the harmonious development of the physical, the mental, and the spiritual powers» (Lin, 2016a: 8;White, 1903: 3) and this defi nition values wholeness of the affective (spiritual), cognitive (mental) and behavioral (physical) aspects as well (Bazaluk & Blazhevych, 2015). A combination of Fractal Information Theory, education defi ned by White, and the 4 components advocated by Glasser a.k.a. feeling (affect), thinking (cognition), acting (behavior) and physiology that forms the dynamic equilibrium dependence assertion evidences the importance of dynamic equilibrium between/among the components of any system. This also supports the wholeness and the unity between the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model in terms of affect, cognition and behavior and in terms of language input and output stages.

Wholeness of Integration Between the 4MAT Teaching and
Learning Model and the Kirkpatrick Four-Level Evaluation Model and Inter-Subsumption among the Two Models and Language Input and Output.
Pursuant to Lin (2013), how Q1-Q3 in the 4MAT Teaching and Learning Model (Caviness, 2007) correspond to social learning theory (Derry, 2013), cognitive development theory (Hanfstingl et al., 2019) and behaviorism (Baum, 2016), respectively, is stated as follows (Lin, 2016a). In accordance with the theoretical foundation aforementioned, the three theories correspond to Levels 1-3 in the Kirkpatrick Four-Level Evaluation Model as well. In other words, Level 1 Reaction in the Kirkpatrick Four-Level Evaluation Model subsumes social learning theory (Derry, 2013) and thus corresponds to the Heart of mankind, the Limbic System in the brain and Dendrites in the neuron, and then to the initial and major stages of language input; Level 2 Learning subsumes cognitive development theory (Hanfstingl et al., 2019) and thus corresponds to the Brain of mankind, the Cortex in the brain and the Soma in the neuron, and then to the stage of language input to output (concept formation); Level 3 Behavior subsumes behaviorism (Baum, 2016) and thus corresponds to the Body of mankind, the Brain Stem in the brain and the Axon in the neuron, and then to language output (Baum, 2016;Caviness, 2007;Derry, 2013;Lin, 2013Lin, , 2016aLin, , 2016bMcCarthy & O'Neill-Blackwell, 2007;Sousa, 2011b). Additionally, how brain processes information, how Levels 1-4 develop, and how language input/output processes are alike and their fi nal outcomes are performed extrinsically equivalent to Service Learning and Results (Perform) in the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model, respectively (Caviness, 2007;Kirkpatrick & Kirkpatrick, 2011, 2019 (Fig. 2).
A deliberate literature review in the preceding paragraphs has identifi ed the 4MAT Teaching and Learning Model with the theoretical foundation of learning performance evaluation as well as the Kirkpatrick Four-Level Evaluation Model with the foundation of teaching design, with implementing into the two Models the components/stages of language input and output. How they inter-subsume and integrate each other not only conforms to interconnectedness (the unity across all) in the 4MAT Teaching and Learning Model using Fractal Information Theory and brain science theory but also corresponds to the oneness between teaching evaluation and teaching design a.k.a. the core idea valued by Kirkpatrick and Kirkpatrick (Caviness, 2007;Lin, 2016aLin, , 2016bKirkpatrick & Kirkpatrick, 2011, 2019.

Conclusions and Suggestions
The 4MAT Teaching and Learning Model published around 40 years ago has the theoretical source of the 4MAT System and its application to teaching has been widely studied and receives the interdisciplinary theoretical foundation including brain science (Caviness, 2007;Lin, 2013Lin, , 2016aMcCarthy & O'Neill-Blackwell, 2007). The Kirkpatrick Four-Level Evaluation Model was published 60 years ago and its wide application to learning performance evaluation has been proven as well (Chen et al., 2012;Hsiao, 2010;Huang & Hsieh, 2011;Lin, 2016b;Reio et al., 2017;United States, 2008). Given that, a combination of brain science theory and Fractal Information Theory has verifi ed initially how the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model subsume and superimpose in terms of the theoretical framework, i.e., the unity between a teaching theory and a learning performance evaluation theory. Such integration not only originates from the inherent unity verifi ed by a thoughtful literature review but also receives theoretical support from interdisciplinary studies. Meanwhile, this integration is intertwined with language input and output in a psycholinguistic/neurolinguistic manner.

A primary investigation using brain science theory and other theories to analyze the integration between the 4MAT Teaching and Learning Model and the Kirkpatrick Four-Level Evaluation Model shows the unity between both models. This investigation led to achieving the purpose of the study: modernizing the methodology of psycholinguistic research. With implementing the components/stages of language input and output as this article proposed, it is expected to be promising in extending and applying both models theoretically and practically in linguistics and other relevant areas in the future. As it comes to studies, it is recommended that the two Models be connected to analyze more teaching models and/or learning performance evaluation models for unity, inquire performance evaluation in collaborations with scenarios in practice, or even associate other disciplines under the implementation of Fractal Information Theory (Lin, 2016b). A possible suggestion for psycholinguistic researchers is to design curricular and lessons based on the Unifi ed Models (Figure 1 and 2) proposed in this study and evaluate instructional effi cacy and student learning performance. Another potential research direction is to use each quadrant of the Unifi ed Models and analyze related components in more specifi c language input and output phases: listening, reading, speaking, writing, and even smaller components in the four types of language skills.
As it comes to practice, especially in psycholinguistics and/ or other relevant disciplines, the key to apply the two target Models simultaneously depends on how to regulate respective quadrants/levels pro rata as well as the wholeness between them to simultaneously achieve «dynamic equilibrium» in the 4MAT Teaching and Learning Model and «The end is the beginning» in the Kirkpatrick Four-Level Evaluation Model (Caviness, 2007;Kirkpatrick & Kirkpatrick, 2011: 60;Kirkpatrick & Kirkpatrick, 2019;Lin, 2013Lin, , 2016aLin, , 2016b. «Dynamic equilibrium» in the 4MAT Teaching and Learning Model (Caviness, 2007;Lin, 2013Lin, , 2016a and «The end is the beginning» in the Kirkpatrick Four-Level Evaluation Model (Kirkpatrick & Kirkpatrick, 2011: 60;Kirkpatrick & Kirkpatrick, 2019) as well as the unity between them in particular can be identifi ed as the important reference to the conception of teaching design and learning performance evaluation in psycholinguistics (Aish & Hanna, 2017). The long-term interdisciplinary studies associated therewith and the inter-subsuming contents thereof evidence the 4MAT Teaching and Learning Model and the Kirkpatrick
