3. selective attention and cognitive inhibition The Stroop color and word Task: (Stroop, 1935) The requirements of the Stroop task is to inhibit the more automatic tendency to read a written word while performing the less automatic task of choosing the color of ink in which the word is written, as fast as possible. The participants are required to identify, as quickly as possible, the ink color of the Hebrew words: red, blue, green and yellow, presented in varying colors (red, blue, green and yellow) and press the correct key. The names of the colors will be printed onto keys on the keyboard (i for red, j for yellow, l for blue and m for green). When the participant presses the correct key, reaction time will be recorded, and the next stimulus appeared. Presentation of word stimuli will be divided into blocks, consisting of four blocks of 16 congruent or incongruent (50% each randomly) colored word stimuli. Maximum stimulus duration and interstimulus durations will be 1,300 and 350 msec, respectively. The task procedure is based on previous studies (Peterson et al. 2009).
