Consequently, SR is an inherent part of EF, making EF inherently future-directed. The developmental progression common to each EF is typified in the internalization of language. As the child matures, speech toward others becomes speech to the self yet, for a time, vocalized. It then progresses to subvocal self-speech and finally to fully covert or private speech that comprises verbal thought. Response inhibition is the capacity to delay a response to an immediate environmental event.
SR is impossible without a delay in that response directed toward immediate reinforcement.
This is done so that the actions occurring during an EF cannot be directly observed by others. I. Nonverbal Working Memory . Among the various senses, the most important to humans are vision and, to a lesser degree, hearing. It is not surprising, then, that this mental module is largely composed of visual imagery and private audition. Undoubtedly the other senses also contribute to this symphony of internalized resensing.
