Abstract

The present set of studies evaluated two specific predictions generated by Eysenck et al.'s (2007) attentional control theory of anxiety-linked task performance. First, to the extent that a task increases the need for working memory capacity, an anxiety-linked performance decrement should become more evident. Second, to the extent that a task increases the likelihood of effort, this anxiety-linked performance decrement should attenuate. Experiments 1 and 2 examined the learning performance of low and high trait anxious participants in capacity-dependent and capacity-independent tasks, under incidental and intentional learning conditions. Experiments 3 and 4 then examined the learning preference of such participants under incidental and intentional learning conditions. The pattern of findings provides direct support for the model's predictions.

1IADS Sound Numbers used were: 110, 277, 278, 279, 351, 815.

2Ratings from 64 students served to determine that these particular sounds, at these particular decibels, differed maximally in affective tone.
