A strong body of research demonstrates associations between the incidence of Alzheimer’s disease and individuals’ personality characteristics, level of social engagement, and educational attainment. To advance understanding of the causal pathways leading to Alzheimer’s, the Board on Behavioral, Cognitive, and Sensory Sciences (BBCSS), with support from the Division of Behavioral and Social Rese...

A growing number of studies demonstrate associations among false-belief understanding (FBU), executive function (EF), and social competence. This study extends previous studies by exploring longitudinal associations among FBU and its correlates within a low-income sample of preschoolers attending Head Start. Sixty-eight children (time 1 mean age = 5 years 2 months) were assessed over their pres...

Associations between occupational factors and characteristics of the social network in people with persistent mental illness were investigated. Participant groups (N= 103) representing three types of daily occupations--working or studying, visiting community-based activity centers, and having no regular daily occupation--were selected for the study. Participants were assessed regarding social i...

OBJECTIVE To better understand age and gender differences in associations of social relationships with chronic inflammation. METHOD Using a sample of middle-aged and older adults ( N = 963) from the Midlife Development in the United States (MIDUS) biomarker project, we examined interactions of age and gender with structural and functional social network measures in predicting interleukin-6 (I...

Previous studies have lacked sufficient power to assess associations between early-life socioeconomic position and adult cause-specific mortality. The authors examined associations of parental social class at age 0-16 years with mortality among 1,824,064 Swedes born in 1944-1960. Females and males from manual compared with nonmanual childhood social classes were more likely to die from smoking-...

Impairments of social cognition are often leading features in frontotemporal lobar degeneration (FTLD) and likely to reflect large-scale brain network disintegration. However, the neuroanatomical basis of impaired social cognition in FTLD and the role of white matter connections have not been defined. Here we assessed social cognition in a cohort of patients representing two core syndromes of F...

BACKGROUND AND OBJECTIVES The importance of biological versus social influences on long-term outcomes of extremely preterm children is debatable. The goal of this study was to determine the relative contributions of biological and social exposures to outcomes into adolescence in extremely preterm survivors, hypothesizing that biological exposures would be more important early, but social exposu...

Recent theory predicts that males should choose social environments that maximize their relative attractiveness to females by preferentially associating with less attractive rivals, so as to enhance their mating success. Using the Trinidadian guppy (Poecilia reticulata), a highly social species, we tested for non-random social associations among males in mixed-sex groups based on two phenotypic...

BACKGROUND Oxytocin (OXT) has been implicated in a suite of complex social behaviors including observed choices in economic laboratory experiments. However, actual studies of associations between oxytocin receptor (OXTR) gene variants and experimentally elicited social preferences are rare. METHODOLOGY/PRINCIPAL FINDINGS We test hypotheses of associations between social preferences, as measur...
