In this study, the authors examined the degree to which social-cognitive career theory (SCCT; R. W. Lent, S. D. Brown, & G. Hackett, 1994) explained the development of social justice interest and commitment. Data from 274 college students and latent variable path modeling were used to test theoretically and empirically derived SCCT direct and indirect effects structural models. The direct effects model estimated the direct effect of social supports and barriers on social justice commitment and the indirect effects model estimated the effect of social supports and barriers indirectly through self-efficacy. Overall, the present findings supported the use of SCCT within the social justice domain, as social justice self-efficacy and outcome expectations were useful in explaining the development of college students' social justice interest and commitment. The present findings supported the indirect effects model of social justice interest and commitment over the direct effects model. Finally, unique to prior tests of SCCT in vocational and academic domains, social supports and barriers exhibited an indirect effect on commitment through outcome expectations. Study limitations, future directions for research, and implications for facilitating college students' social justice interest and commitment are discussed.

Individual differences in the capacity for information processing in complex tasks can be predicted from both personality and temperament that derive from both the biological and social substrates of human development and behavior. If there are cultural differences in brain structure and function that govern information processing, then two different cultures may show biologically based temperamental differences in sensitivity to stimulation (e.g., Pavlov's Strength of the Nervous System) which in turn may predict individual differences in capacity for tolerating environmentally determined stimulus overloads. We examined the relationship between biologically based measures of Pavlovian Temperament (Strength of Excitation, Inhibition, and Mobility) and an individual differences measure consisting of five dimensions of capacity for tolerating information load. Both direct and indirect effects of country of origin on capacity for information processing were tested in a mediated path analytic model in which Pavlovian Excitation, Inhibition, and Mobility were hypothesized to mediate the relationship between culture and self-reported information processing capacities. Keywords personality, cultural psychology, measurement/statistics, information processingIn recent years, our research group has been focused on the task of identifying and studying the stimulus and information processing demand characteristics that may exist in a wide variety of occupations (Haase, Ferreira, Santos, Aguayo, & Fallon, 2008;Haase et al., 2011). The purpose of this work has been to quantify the extent to which occupations inherently exert these demand characteristics and how occupations differ in the stimulus and information processing demands they place on their occupants.
