To organise future behaviour, it is important to remember both the central and contextual aspects of a situation. We examined the impact of contextual threat or safety, learned through verbal instructions, on face identity recognition. In two studies (N = 140), 72 face–context compounds were presented each once within an encoding session, and an unexpected item/source recognition task was performed afterwards (including 24 new faces). Hierarchical multinomial processing tree modelling served to estimate individual parameters of item (face identity) and source (...) memory (threat or safety context) as well as guessing behaviour. Results show that language was highly effective in establishing threatening and safe context conditions. In Study 1, a fleeting picture stream (1 s per picture) led to poor item and source recognition. Prolonged presentation times (Study 2 with 6 s per picture) improved face memory but no contextual modulation was observed. Thus, incidental face learning was surprisingly poor and rapidly changing contextual settings might have interfered with the accurate encoding of face identity information and item–source binding.

Personality and Cognitive Performance The two experiments reported here are concerned with the influence of trait anxiety and other individual differences on cognitive performance using the face-in-the-crowd procedure. Participants completed questionnaires and across two experiments searched for discrepant faces in matrices of otherwise identical faces. The key findings from this study indicated that anxiety enhanced processing efficiency of positive emotional material when interacts with high psychoticism. Additionally, the vigilance for threatening and neutral faces was a characteristic of sanguine individuals with (...) repressive coping while inefficient processing of threatening and neutral stimuli of non-defensive melancholic subjects. These results are discussed with reference to attentional control theory. (shrink)

The present work shows the existence of systematic individual differences in change blindness. It can be concluded that the sensitivity for changes is a trait. That is, persons differ in their ability to detect changes, independent from the situation or the measurement method. Moreover, there are two explanations for individual differences in change blindness: a) capacity differences in visual selective attention that may be influenced by top-down activated attention helping to focus attention onto relevant stimuli b) differences in working memory (...) capacity or in decision making. In accordance with this, age-related individual differences in the sensitivity for changes can be explained by attentional processes and by confidence in the own ratings. Together, the present work might form the basis for a more application-oriented research on individual differences in change blindness and its underlying processes. (shrink)

Countless studies have reported that individuals detect threatening/angry faces faster than happy/neutral faces. Two classic views have been used to explain this phenomenon—that negative valence drives the effect, or conversely, that low-level perceptual characteristics of the stimuli are responsible for their rapid detection. In the current review, I question whether dichotomous perspectives are the most parsimonious way to explain a large and inconsistent literature. Further, I argue that nondichotomous, multicomponent accounts for the detection of emotionally valenced stimuli might help take (...) us beyond traditional approaches to visual detection research, and I suggest various ways in which future research can use these newer approaches to more effectively elucidate the mechanisms underlying the rapid detection of emotionally valenced stimuli.
