Individuality and relatedness of the self: an autophotographic study.

Using R. C. Ziller's (1990) method of autophotography, the authors studied the duality of relatedness and individuality. A total of 226 young adults used photos (and words) to portray "who they are". Photo essays were scored for objective codes (e.g., people touching) and subjectively rated for individuality (richness of self-depiction). As predicted, persons who emphasized their personal rather than social identity depicted greater individuality; relatedness was associated with social and collective identity. Other results replicated earlier gender differences in relatedness and associations of individuality and relatedness with the 5-factor model. In the 2nd wave of the sample, individuality was associated with higher ego development, maturity, and self-directed values; low individuality was associated with restrictive conformity and security values. The authors suggest that the combination of individuality and relatedness is optimal for human development.

Reported head injury and sex differences in color naming, color matching, and digit-string matching.

It was hypothesized that the observed sex differences on three speeded tasks could be accounted for in terms of the greater incidence of head injury in men than in women. In two studies of 64 male and 66 female college students significant sex differences were found on digit-string matching and color-matching tasks. When the data from those 39 subjects with reported histories of head injury were eliminated from the analysis or head-injury reports were statistically controlled, significant sex differences remained. Digit-string matching times were significantly correlated with reported head injury in both studies, suggesting that this test is sensitive to residual effects of head injury.
