Objective. The purpose of the protocol is to extend the structured event complex (SEC) model developed by the principal investigator. Grafman (Grafman, 1995) proposed that action sequences are represented in form of SECs in the human prefrontal cortex (PFC). An SEC is a goal-oriented set of events that is sequentially structured and represents thematic knowledge, morals, abstractions, concepts, social rules, event features, event boundaries, and grammars. There are both temporal and semantic associative relations between subcomponents of SEC knowledge. We will investigate hypotheses regarding the role of different regions within the PFC in processing associative relations. We will also investigate how SECs differing in psychological dimensions such as temporal duration, complexity, and familiarity are represented and activated in the PFC. We will further examine the temporal and semantic organization of SEC subcomponents by investigating how the goal and outcome structure of event knowledge is represented and activated in the PFC. Further, we will investigate how the temporal location of events within SECs are represented and activated in the PFC. We will also investigate how goals and outcomes specifying the temporal order and duration of SEC subcomponents are processed within the PFC. Additional objectives are to (1) investigate the neural representation of human emotions and decision-making based on utility estimation; (2) investigate the relationships between cognitive and neural substrates of moral emotions and judgment (Moll et al., 2002a; Moll et al., 2002b) with those of the SEC model developed by the principal investigator (Grafman, 1995); and (3) probe a new construct of cognitive dimensions incorporating critical explanatory variables in social cognition such as moral emotions and social event knowledge.
