Sentences with phrase «social brain analyses»

«The original social brain analyses showed that social group size does not correlate especially well (if at all) with total brain size, but only with neocortex size... That would be difficult to reconcile with their claim.»

Not exact matches

The team's analyses, which covered 90 species, revealed that brain size was best predicted by a score based on various social behaviors such as cooperation with other species, group hunting and complex vocalizations.

As described in the main text, ordered logistic regression analyses were carried out for each brain region in which social network distances were modeled as a function of local neural response similarities and dyadic dissimilarities in control variables (gender, ethnicity, nationality, age, and handedness).

To gain insight into what brain regions may be driving the relationship between social distance and overall neural similarity, we performed ordered logistic regression analyses analogous to those described above independently for each of the 80 ROIs, again using cluster - robust standard errors to account for dyadic dependencies in the data.

Following a large - scale analysis of primates, Higham and his colleague Alex DeCasien are confident that the social brain theory does not tell the whole story.

Assessing sources of error in comparative analyses of primate behavior: intraspecific variation in group size and the social brain hypothesis.

«Because of the small number of studies published, we were not able to perform additional analysis to compute brain maps for social and moral subdomains separately.

Zinchenko and her colleague, Marie Arsalidou, conducted a meta - analysis of 36 previous studies that used functional magnetic resonance imaging (fMRI) to examine brain responses to social norms — such as fairness — and violations of norms.

A veterinary behaviorist has also demonstrated their academic skills in graduate school classes such as ethology, evolution of social behavior, developmental biology, neurobiology of behavior, learning theory, animal cognition, psychopharmacology (study of medications that affect the brain and emotions), and statistical analysis.

To examine whether the relationship between pubertal status and neural response to social evaluation differed for healthy youth and controls, similar whole brain regression analyses were conducted to identify areas showing group × pubertal status interaction effects.

Whole - brain analyses also revealed greater activity in the dACC in MDD compared with healthy youth to social exclusion, but only from 7 to 9 s after receiving rejection feedback.

Given their typical age of onset, a broad range of mental disorders are increasingly being understood as the result of aberrations of developmental processes that normally occur in the adolescent brain.4 — 6 Executive functioning, and its neurobiological substrate, the prefrontal cortex, matures during adolescence.5 The relatively late maturation of executive functioning is adaptive in most cases, underpinning characteristic adolescent behaviours such as social interaction, risk taking and sensation seeking which promote successful adult development and independence.6 However, in some cases it appears that the delayed maturation of prefrontal regulatory regions leads to the development of mental illness, with neurobiological studies indicating a broad deficit in executive functioning which precedes and underpins a range of psychopathology.7 A recent meta - analysis of neuroimaging studies focusing on a range of psychotic and non-psychotic mental illnesses found that grey matter loss in the dorsal anterior cingulate, and left and right insula, was common across diagnoses.8 In a healthy sample, this study also demonstrated that lower grey matter in these regions was found to be associated with deficits in executive functioning performance.
