Depression vs. paranoia: why are there sex differences in mental illness?

Being there: a brief visit to a neighbourhood induces the social attitudes of that neighbourhood

There are differences between human groups in social behaviours and the attitudes that underlie them, such as trust. However, the psychological mechanisms that produce and reproduce this variation are not well understood. In particular, it is not clear whether assimilation to the social culture of a group requires lengthy socialization within that group, or can be more rapidly and reversibly evoked by exposure to the group's environment and the behaviour of its members. Here, we report the results of a two-part study in two neighbourhoods of a British city, one economically deprived with relatively high crime, and the other affluent and lower in crime. In the first part of the study, we surveyed residents and found that the residents of the deprived neighbourhood had lower levels of social trust and higher levels of paranoia than the residents of the affluent neighbourhood. In the second part, we experimentally transported student volunteers who resided in neither neighbourhood to one or the other, and had them walk around delivering questionnaires to houses. We surveyed their trust and paranoia, and found significant differences according to which neighbourhood they had been sent to. The differences in the visitors mirrored the differences seen in the residents, with visitors to the deprived neighbourhood reporting lower social trust and higher paranoia than visitors to the affluent one. The magnitudes of the neighbourhood differences in the visitors, who only spent up to 45 min in the locations, were nearly as great as the magnitudes of those amongst the residents. We discuss the relevance of our findings to differential psychology, neighbourhood effects on social outcomes, and models of cultural evolution.

Intimacy motivation and subjective mental health in a nationwide sample

Over 1,200 adults in a representative nationwide sample were administered the Thematic Apperception Test (TAT) and an unstructured interview which produced 25 measures of subjective mental health and ultimately six factor scores: unhappiness, lack of gratification, strain, feelings of vulnerability, lack of self-confidence, and uncertainty. The TATs were scored for intimacy motivation (McAdams, 1980)--a recurrent preference or readiness for experiences of warm, close, and communicative interaction with others. Controlling for age, education, and their interaction, high intimacy motivation in women was associated with greater happiness and gratification, whereas in men it was associated with lack of strain and lack of uncertainty. Women high in intimacy motivation who were living alone reported lower levels of gratification and more uncertainty in their lives than other women. Intimacy motivation also declined significantly over the life span for women, but not for men. Finally, demographic effects on intimacy motivation were examined. Controlling for age, education, and their interaction, professional men (e.g., doctors, lawyers, and teachers) scored higher on intimacy motivation than did men in other occupational categories, while among women the occupational groups with highest intimacy motivation were service workers and craftspersons.
