Performance/Revelle/Resource theory/cognitive psychology/Matthews: Humphreys-Revelle Theory: Humphreys and Revelle (1984)(1) described separate resource pools for sustained information transfer (SIT; similar to attention) and for short-term memory (STM). Arousal, in their model, leads to increased availability of SIT resources, but loss of STM resources. Directing effort to the task is distinct from arousal, and influences SIT resources only. Traits that influence arousal and effort will then have differing effects on qualitatively different tasks, overcoming a major weakness of traditional arousal theory.

1) The Humphreys and Revelle (1984)(1) theory attributes Extraversion x arousal interactions to variations in resource availability. Hence, these interactive effects should be found primarily with those more demanding tasks that are highly resource-limited, rather than simple tasks requiring little attentional capacity. A review of the evidence (Matthews 1997)(2) failed to confirm this prediction. In fact, interactive effects of Extraversion and arousal on performance were most reliable with rather simple, routine encoding tasks, as opposed to demanding, resource-limited tasks (Matthews 1997(2); Matthews and Harley 1993(3)). Alternative mechanisms such as automatic activation processes may provide a better explanation, as explored in a study that modelled the effect using neural nets (Matthews and Harley 1993)(3). >VsResource Theory.
