People and institutions around the world have been affected by the Coronavirus Disease 2019 (COVID-19). Herein, we investigate the role of both basic (HEXACO and Big Five) and specific (Dark Factor of Personality, Narcissistic Rivalry and Admiration) personality traits for 17 criteria related to COVID-19, grouped into (i) personal perceptions in terms of risks and worries about the disease, (ii) behavioral adjustments in terms of following the health recommendations and hoarding, and (iii) societal evaluations in terms of the appropriateness of different measures and feelings of social cohesion. (Internal) Meta-analytic results across five samples from two countries (overall N = 10,702) show—next to gender and age effects—the importance of several traits, including Emotionality/Neuroticism for personal perceptions and anti- or prosocial traits for behavior in line with health recommendations. The investigation thus highlights the importance of individual differences in uncertain and changing situations and the COVID-19 pandemic in particular.

Visual perception is not only shaped by sensitivity, but also by confidence, i.e. the ability to estimate the accuracy of a visual decision. There is robust evidence that younger observers have access to a reliable measure of their own uncertainty when making visual decisions. This metacognitive ability might be challenged during aging due to increasing sensory noise and decreasing cognitive control resources. We investigated age effects on visual confidence using a confidence forced-choice paradigm. We determined discrimination thresholds for trials in which perceptual judgements were indicated as confident and for those in which they were declined as confident. Younger adults (19-38 years) showed significantly lower discrimination thresholds than older adults (60-78 years). In both age groups, perceptual performance was linked to confidence judgements, but overall results suggest reduced confidence efficiency in older adults. However, we observed substantial variability of confidence effects across all particpants. This variability was closely linked to individual differences in cognitive control capacities, i.e. executive function. Our findings provide evidence for age-related differences in meta-perceptual efficiency that present a specific challenge to perceptual performance in old age. We propose that these age effects are primarily mediated by cognitive control resources, supporting their crucial role for metacognitive efficiency.

Age And Sex

The study described in this chapter examines whether individual differences in six rating-based bonobo personality dimensions—assertiveness, conscientiousness, openness, attentiveness, agreeableness and extroversion—are related to sex, age, behaviours and dominance. To these ends, the study tested predictions based on previous studies of human and chimpanzee personality, and bonobo behaviour and socio-ecology. Sex and age differences in assertiveness, openness and extroversion, and correlations between these personality dimensions and behaviour were consistent with predictions. Conscientiousness showed associations with observed behaviours but requires further investigation as sex and age effects differed from those reported in humans and chimpanzees. Agreeableness and attentiveness showed few associations with age, sex and behaviours, indicating the need to further investigate validity of these factors. This chapter shows that personality dimensions in bonobos are correlated with sex, age and behaviours in ways that are consistent with what is known for bonobos and their socio-ecology. L’étude décrite dans ce chapitre examine si les différences individuelles dans six dimensions de personnalité bonobos basées sur évaluation—Affirmation de soi, Conscience, Ouverture, Attention, Agréabilité, et l’Extroversion—sont liées au sexe et l’âge et les comportements et la dominance. L’étude a testé les prédictions basées sur des études précédentes de la personnalité humaine et chimpanzé, et le comportement bonobo et la socioécologie. Les différences de sexe et d’âge dans l’Affirmation de soi, l’Ouverture et l’Extroversion et les corrélations entre ces dimensions de personnalité et de comportement étaient cohérents avec nos prédictions. La Conscience montre des associations avec les comportements observés mais a besoin plus de recherche vu que les effets du sexe et de l’âge diffèrent des effets rapportés chez les humains et les chimpanzés. L’Agréabilité et l’Attention n’avaient pas autant d’associations avec l’âge, le sexe et les comportements. Cela montre qu’il faut plus rechercher la validité de ces facteurs. Cette étude montre que les dimensions de personnalité chez les bonobos sont corrélé à l’âge, au sexe et aux comportements de manières qui sont cohérentes avec notre connaissance des bonobos et de leur socioécologie.
