Well-being and the accessibility of pleasant and unpleasant concepts

The trait-congruency hypothesis predicts that persons high in positive or negative trait affect more readily process pleasant or unpleasant stimuli, respectively. In two studies, participants were administered measures of personality and affect. Moreover a yes/no lexical decision task with pleasant, unpleasant and neutral words was administered in Study 1, whereas a go/no-go task was used in Study 2. Several methods to increase reliabilities of differences in reaction times are explored. Correlations of measures of personality and trait affect with decision times were mostly consistent with the trait-congruency hypothesis, particularly for decision times in the go/no-go task that measured individual differences in valence-specific decision times more reliably. The findings suggest that trait-related concept accessibility is one source of trait congruity. Copyright (c) 2006 John Wiley & Sons, Ltd.
