Introversion and working memory

1. Introduction Over the past half century, foreplay accounts have dominated explanations of the di•erences between introverts and extraverts (Eysenck, 1967; Humphreys & Revelle, 1984). Because stimulation is a noncognitive variable, it has been di†cult for cognitive psychologists to bridge levels of nominate in attempting to understand the likeness between the cognitive and the psychophysiological master key person®les of extroversion. Di•erences in neurochemistry and neuroanatomy ar generally far to a greater extent obedient to modular or neural circuitry-based views of cognition. The fretted physical composition in the brainstem, long cited as the anatomical source of arousal di•erences associated with extraversion (Eysenck, 1967), has recently been shown to handle controlupstream over certain cortical and subcortical areas of the brain. Speci®cally, the pontine reticular marrow projects to two the prefrontal cerebral mantle and the primary ganglia modulating the release of dopamine (DA; Martin, 1996; Robbins & Everitt, 1995). Each of these areas is central to high cognitive functions. Dorsolateral prefrontal mantle (DLPFC) is involved in working recollection (Cabeza & Nyberg, 1997), objet dart the basal ganglia is central to adjectival remembering formation (Lieberman, in middle ear of fish; Saint-Cyr & Taylor, 1992).

Furthermore, both DLPFC and basal ganglia regard on DA for standard mathematical operation (Cohen & Servan-Schreiber, 1992; Spitzer, 1993; Wickens & Kotter, 1995). These advances in mapping the neuroanatomical and neurochemical links from the reticular formation to other(a) areas of the brain o•er new avenues of insight into the cognitive consequences of arousal di•erences. Based on these ®ndings, it should be expected that extraverts and introverts would di•er both in their working memory and their procedural memory. The expected di•erence in procedural memory has been base by Corr and colleagues (Corr, Pickering & Gray, 1995).
