Sociality relies on motivational and cognitive components that may have evolved independently, or may have been linked by phenotypic correlations driven by a shared selective pressure for increased social competence. Furthermore, these components may be domain-specific or of general-domain across social and non-social contexts. Here, we used zebrafish to test if the motivational and cognitive components of social behavior are phenotypically linked and if they are domain specific or of general domain. The behavioral phenotyping of zebrafish in social and equivalent non-social tests shows that the motivational (preference) and cognitive (memory) components of sociality: (1) are independent from each other, hence not supporting the occurrence of a sociality syndrome; and (2) are phenotypically linked to non-social traits, forming two general behavioral modules, suggesting that sociality traits have been co-opted from general-domain motivational and cognitive traits. Moreover, the study of the association between single nucleotide polymorphisms (SNPs) and each behavioral module further supports this view, since several SNPs from a list of candidate "social" genes, are statistically associated with the motivational, but not with the cognitive, behavioral module. Together, these results support the occurrence of general-domain motivational and cognitive behavioral modules in zebrafish, which have been co-opted for the social domain.

Oral health is important for the overall health of an individual, particularly older adults. However, a number of obstacles frequently prevent older people from receiving timely and appropriate dental care. These obstacles are intricate and multifaceted, involving systemic diseases, cognitive elements, and psychological, financial, and educational issues.

Introduction: There is an ongoing debate about the neural mechanisms and subjective preferences involved in the processing of social rewards compared to non-social reward types.
Methods: Using whole-brain functional magnetic resonance imaging (fMRI), we examined brain activation patterns during the anticipation and consumption phases of monetary and social rewards (using the Monetary and Social Incentive Delay Task-MSIDT, featuring human avatars) and their associations with self-reported social reward preferences measured by the Social Reward Questionnaire (SRQ) in 20 healthy right-handed individuals.
Results: In the anticipation phase, all reward types activated the dorsal striatum, middle cingulo-insular (salience) network, inferior frontal gyrus (IFG), and supplementary motor areas.

Criterion shifting reflects a complex interplay between cognitive strategies and external influences, yet individuals differ markedly in their tendency to adjust decision thresholds. While some readily adapt their criteria in response to task demands, others maintain more rigid thresholds, raising questions about the extent to which external pressures - such as social influence - can drive greater flexibility. Findings from social psychology reveal that social pressure can heavily impact individual decision-making, suggesting that such pressures may also impact individual criterion shifting tendencies.

Our understanding of how the medial temporal lobe (MTL) contributes to human cognition has advanced enormously over the past half a century. My work in the 1990s characterizing the role of recollection and familiarity processes in episodic memory led me to study the MTL's role in these two memory processes. In the current paper, I provide a personal commentary in which I describe the motivating ideas, as well as the invaluable impact of mentors, colleagues, and students that led to a series of studies showing that conscious recollection is critically dependent on the hippocampus, whereas familiarity-based judgments are dependent on regions such as the perirhinal cortex.

Introduction: Although marathon events have gained global popularity and align closely with public health objectives, limited research has explored how individuals perceive the attractiveness of these events and how such perceptions influence participation intention. This study introduces the concept of "perceived attractiveness" as a multidimensional evaluation encompassing emotional, symbolic, cultural, and convenience facets related to participation. Drawing upon self-determination theory and self-efficacy theory, the study investigates how perceived attractiveness predicts participation intention, mediated by exercise-related self-efficacy.
