Differential Psychology


differential psychology, branch of psychology that deals with individual and group differences in behaviour. Charles Darwin’s studies of the survival capabilities of different species and Sir Francis Galton’s researches on individual visual and auditory skills, as well as more recent experiments, have shown that both individual and group differences are quantitative rather than qualitative. Persons do not fall into sharply separated types, such as bright and dull, maladjusted and normal, introvert and extravert. On the contrary, in all psychological characteristics, individuals vary by degree along a continuous scale.

Plos One : Are Autobiographical Memories Inherently Social Evidenc...

By: James Kilner

Description : The story of our lifetime – our narrative self – is constructed from our autobiographical memories. A central claim of social psychology is that this narrative self is inherently social : When we construct our lives, we do so in a real or imagined interaction. This predicts that self-referential processes which are involved in recall of autobiographical memories overlap with processes involved in social interactions. Indeed, previous functional MRI studies ...

By: Xi-nian Zuo

Description : Recent studies have demonstrated developmental changes of functional brain networks derived from functional connectivity using graph theoretical analysis, which has been rapidly translated to studies of brain network organization. However, little is known about sex- and IQ-related differences in the topological organization of functional brain networks during development. In this study, resting-state fMRI (rs-fMRI) was used to map the functional brain netwo...

Ethnic Discrimination : A Critical Survey of Economic Explanations

By: Jomo K. S., Professor

Economics

Ethnic discrimination has not been the subject of much theoretical consideration in economics. Typically, ethnic relations are relegated to the realm of sociology, and less commonly to politics, social psychology or social anthropology. Nevertheless, perhaps owing to its political significance in the United States, various economists have attempted to offer economic explanations for the phenomenon of ethnic discrimination, drawing largely on the US experience, particular...

Medical Reference Publication

Introduction A reduction of at least one-third in the proportion of infants with low birth weight is one of the seven major goals for the current decade of the “A World Fit for Children” programme of the United Nations. Moreover, nutritional deprivation — the major determinant of low birth weight — is a clear obstacle to the attainment of many of the Millennium Development Goals (1).
