    ABSTRACT: First-year college students were asked to complete alcohol consumption and identity status questionnaires-currently and retrospectively. Trend analyses of the retrospective data and current data revealed somewhat similar inverse linear trends for identity status on absolute annual alcohol consumption. In both cases, identity sophistication was associated with lower levels of consumption. Of the students who reported an increase in consumption from the junior year of high school to the first year of college, those displaying progressive identity development reported a relatively lower increase in consumption than those displaying stable identity status. This difference approached the conventional level of significance. The implications of these findings are explored.

    ABSTRACT: This study examines the factor structure of scores on the English-language version of the Structure of Temperament Questionnaire. Scores from 300 college students were subjected to maximum-likelihood confirmatory factor analyses (CFA). A first-order model consisting of eight correlated factors and a second-order model consisting of two superordinate factors and eight first-order factors were tested. The results of the analyses indicate that the first-order correlated model is the best fit for the data. The English-language version of the Structure of Temperament Questionnaire can be used to measure eight correlated yet theoretically unique dimensions of temperament.

    ABSTRACT: Kin selection theory predicts that grandparents will differentially invest in their grandchildren as a function of paternity certainty. This study explored the hypothesis of "discriminative grandparental solicitude" (Euler and Weitzel, 1996; Smith, 1988) in a sample of college students. Students with four living grandparents were asked to indicate the frequency of various behaviors received from or directed to each grandparent. A significant linear trend on a majority of the measures supported this hypothesis. Reported contact and closeness were highest with the maternal grandmother (most genetically certain) and lowest with the paternal grandfather (least genetically certain); maternal grandfathers and paternal grandmothers were intermediate. The "preferential investment hypothesis" (Laham, Gonsalkorale, and von Hippel, 2005) predicts that the investment behavior of the maternal grandfather and the paternal grandmother should differ only when there are cousins through the father's sisters. Contrary to the predictions of this hypothesis, grandchildren did not rate the maternal grandfather consistently higher on any of the indices when more certain investment outlets were available to the paternal grandmother.
