510). As one of its major functions, the frontal lobe bears responsibility for administering the code by which the patterns of social behavior are put into operation and by which the individual integrates and regulates its conduct in respect of that of other individuals. We postulated that there is a special form of social intelligence by which the organism maintains the running, changing stream of social relationships and that the frontal lobes bear important, if not unique, responsibility for this.

Using three tasks commonly used to assess these constructs and college students as participants, Miyake et al. found evidence for such a fractionating of EF. But Shute and Huertas (1990) also gave a battery of seven EF tasks to college students and identified four factors—flexibility/perseveration (or set shifting), perceptual–motor speed (probably not an EF), verbal working memory, and time estimation. These factors mainly reflected the tests in the battery. , 1996), five factors were identified from their battery of six EF tasks.

Hayes et al. argued that EF tasks place people in situations where previously learned sources of behavioral regulation come into conflict with rules laid down by the task and examiner. Those task-specific rules are competing with behavior that is otherwise automatic and well practiced. Thus, the typical automatic flow of behavior must be interrupted and delayed long enough for the person to discover a new rule or select among previously learned rules that may apply in this situation. Yet interrupting a well-practiced behavior itself often requires that a rule be selected and followed that is initiating the delay in responding.
