Psychology Faculty Publications

Previous work from our laboratories has shown that juvenile Fischer 344 (F344) rats are less playful than other strains and also appear to be compromised in dopamine (DA) functioning. To determine whether the dysfunctional play in this strain is associated with deficits in the handling and delivery of vesicular DA, the following experiments assessed the extent to which F344 rats are differentially sensitive to the effects of amphetamine. When exposed to amphetamine, striatal slices obtained from F344 rats showed a small increase in unstimulated DA release when compared with slices from Sprague–Dawley rats; they also showed a more rapid high …

What Develops In Moral Identities? A Critical Review, Tobias Krettenauer, Steven Hertz

Psychology Faculty Publications

According to the standard model of moral identity development, moral identities emerge during adolescence and early adulthood. Contrary to this assumption, however, moral identity research has consistently failed to demonstrate any age-related change in this developmental period. The present paper discusses implications of this non-finding. It is argued that researchers need to broaden the scope of inquiry and include developmental aspects of the moral identity construct that have been neglected in the past. Three areas are identified where moral identity development likely occurs in adolescence and beyond: (1) context-dependent differentiation and integration of the self-importance of moral values, (2) growth …

Cross-Cultural Perspectives After Participation In The Yes Program: A Pilot Study, Vanessa E. Fuentes, Elizabeth A. Goncy, Kevin S. Sutherland

Psychology Faculty Publications

Guided by empowerment and ecological theories, the

Youth Empowerment Solutions (YES) program facilitates character

development through activities based in cultural differences, team

building, and social change. This pilot study consisted of two focus

groups (n = 13) of middle school youth conducted after their

participation in an abbreviated version of the YES program.

Specifically, the present study examined youth’s cross-cultural

perspectives after participation. The focus groups were transcribed

and coded for emergent themes using Heaton’s (2005)

supplementary data analysis framework. Qualitative analysis

resulted in two emergent themes: 1) enhanced appreciation for

similarities and differences in cultural and ethnic backgrounds, and …
