Slow Learning

Facial expressions of emotion can convey information about the world and disambiguate elements of the environment, thus providing direction to other people’s behavior. However, the functions of facial expressions from the perspective of learning patterns over time remain elusive. This study investigated how the feedback of facial expressions influences learning tasks in a context of ambiguity using the Iowa Gambling Task. The results revealed that the learning rate for facial expression feedback was slower in the middle of the learning period than it was for symbolic feedback. No difference was observed in deck selection or computational model parameters between the conditions, and no correlation was observed between task indicators and the results of depressive questionnaires.

Social Adversity

In 2004, the Bangor Gambling Task (BGT) was put forward as a simplified of the Iowa Gambling Task (IGT) - one of the primary experimental paradigms used to assess emotion-based decision making under uncertainty. We aimed to investigate the suitability of the BGT as a longer-term re-assessment tool of the IGT. Method: Using a N = 176 focused subsample of the large ongoing prospective cohort study Tracking Adolescents’ Individual Lives Survey (TRAILS), we investigated three suitability criteria with regard to: 1) incremental learning patterns within each task, 2) correlation between the net-scores of tasks, and 3) within-level change in emotion-based decision-making by social stress as predicted by evolutionary theories. One out of three suitability criteria were met, that is, we found similar incremental learning patterns in gambling performance as reported in 2004, but no correlation between net scores of both tasks, nor a decrease in approach-related gambling choices in individuals exposed to social adversity versus controls. Although the BGT may be a useful tool for clinical neuropsychologists, it may be less suited to test changes in adolescents’ decision making performance in combination with the IGT over a larger time frame.

Facial Expressions Of Emotion

Abstract. Past research suggests that transient mood influences the perception of facial expressions of emotion, but relatively little is known about how trait-level emotionality (i.e., temperament) may influence emotion perception or interact with mood in this process. Consequently, we extended earlier work by examining how temperamental dimensions of negative emotionality and extraversion were associated with the perception accuracy and perceived intensity of three basic emotions and how the trait-level temperamental effect interacted with state-level self-reported mood in a sample of 88 adults (27 men, 18–51 years of age). The results indicated that higher levels of negative mood were associated with higher perception accuracy of angry and sad facial expressions, and higher levels of perceived intensity of anger. For perceived intensity of sadness, negative mood was associated with lower levels of perceived intensity, whereas negative emotionality was associated with higher levels of perceived intensity of sadness. Overall, our findings added to the limited literature on adult temperament and emotion perception.
