There is growing interest in psychophysiological and neural correlates of psychopathology, personality, and other individual differences. Many studies correlate a criterion individual difference variable (e.g., anxiety) with a psychophysiological measurement derived by subtracting scores taken from two within-subject conditions. These subtraction-based difference scores are intended to increase...

The aim of this study was to examine the role that personality traits, empathy traits, and gratitude have on ageist attitudes and aging anxiety. Consistent with previous research, participants who exhibited greater aging anxiety were more prone to ageist attitudes. Participants with greater dispositional gratitude exhibited significantly less aging anxiety and less ageist attitudes. All of the ...

Identifying organisms is a key step in accessing information related to the ecology of species. But unfortunately, this is difficult to achieve due to the level of expertise necessary to correctly identify and record living organisms. To try bridging this gap, enormous work has been done on the development of automated species identification tools such as image-based plant identification or aud...

Search task characteristics are recognized as important factors that affect search process and its outcomes. This research examines the relationships among operational measures of searcher’s behavior, individual cognitive differences, subjective task difficulty and mental effort assed by dual-task performance. A web-based information study was conduced in a controlled experimental setting. Fort...

We examine the Cournot oligopoly model in the context of social and individual learning. In both models of learning, firms update their decisions about how much to produce via variants of the genetic algorithm updating procedure. Arifovic (1994) found that both models of social and individual learning converged to the Walrasian, competitive equilibrium. Vriend (2000) reports that the model of s...

Dyads composed of unacquainted females watched a video while snacking on pizza. Their extraversion and self-monitoring scores were used to predict the extent to which individuals within dyads matched each other's food intake. Matching of intake was high irrespective of the personality composition of the dyad. We consider elements of the situation that enhanced matching and whether personality m...

Driver boredom has received little research attention in efforts to develop understanding of driver behaviour and further road safety. This study aimed to develop understanding of relationships between individual differences and driver boredom as well as between driver boredom and driver behaviour. A self-report questionnaire was developed and used to gather data pertaining to individual differ...
