What non-Humans Can Teach us about the Role of Emotions in Cultural Evolution

The role emotions play in the dynamics of cultural phenomena has long been neglected. The collection of articles recently published in Emotion Review provides an important first step into this necessary endeavor. In this commentary, we discuss this contribution by emphasizing the role epistemological parsimony should play in the future of this research agenda. The cultural behavior and emotions of chimpanzees is taken as reference.

Individual Differences in Emotional Appraisal during Development: Analysis of the Role of Age, Gender, and Appraisal Accuracy

Emotional appraisal is the process by which different responses are generated from subjective assessments of different stimuli. Children and adults can react differently to the same stimulus. Emotional appraisal is crucial to define emotional processing and its consequent response rather than the properties of the stimulus itself. Age and gender modulate emotional appraisal during development. This study analyzed emotional appraisal in children aged 4 to 8-years-old. The children's emotional appraisal responses and the appraisal accuracy to images with positive, negative, and neutral valence be compared between the different age groups, and according to the gender of the participants. About the appraisal accuracy, the comparisons indicated significant differences for positive and negative images according to the age of the participants, with no differences in the appraisal accuracy of neutral images. Differences in appraisal accuracy for negative images were observed between the 4-years-old group compared to the 7- and 8-years-old group, as well as in 5-years-old participants compared to 7-years-old. Significant differences were found for the positive and negative images between girls and boys, but no differences were found for neutral images. Girls had more appraisals accuracy for positive and negative images. This work highlights the importance of analyzing individual differences associated with emotional processing at different stages of development. This interrogates research findings in which emotional appraisal is carried out considering the valence assigned by adults and highlights the need for a methodological approach that includes individual differences in the appraisal of stimuli used during development.
