Cultural Involvement and Preference in Immigrant Acculturation

Measures of cultural involvement (CI) and cultural preference (CP) incorporate Berry’s integration, assimilation, separation, and marginalization outcomes, locating them at the ends of two axes suggested by Szapocznik et al. (International Journal of Intercultural Relations, 4 (3–4), 353–365, 1980) in a bidimensional space formed by origin culture and destination culture scales. Each measure combines information from both origin culture and destination culture scales, retains the continuous properties of these scales, connects two of the four-category acculturation outcomes, and has theoretical significance and potential comparability across studies of different immigrant populations. Together they offer a quantitative measure of variations in the structural relation between an immigrant group and its new destination culture, and should reveal new insights into the acculturation process.     

Organizational entry and exit: An exploratory longitudinal examination of early careers

New college graduates' perceptions of organizational entry constructs were measured at the end of the first year of employment and related to subsequent turnover as well as work attitudes 3 years later in a longitudinal design. The research design examined the simultaneous effects of entry constructs for the first time in an exploratory model. The combined effects of individual readiness, organizational tactics, individual tactics, entry process perceptions, perceived job characteristics, learning, expectations, and coping responses on subsequent turnover and job attitudes of newly employed college graduates were investigated using hierarchical logistic regression. Aspects of preemployment anticipation, organization receptivity, adaptation difficulty, meeting with person previously in the position, feedback seeking, and organization attachment correctly predicted 73.3% voluntary turnover after Year 1. Organization entry constructs and first year attitudes explained 45% of the variance in organizational commitment and 48.9% of organizational attachment 3 years later. Preliminary evidence suggests mediated causal paths link other aspects of newcomer perceptions, work attitudes, and turnover.     

What makes male mice paternal?

Both copulation and postcopulatory cohabitation with pregnant females reduce infanticide and enhance paternal responsiveness in male CS1 mice. The effectiveness of copulation in this process, however, depends on the number of occasions that males have previously encountered infants. Infanticidal males which have been subordinated in brief encounters with other males are less likely to commit infanticide in subsequent tests than are those which became dominant to other males. Males which copulate and cohabit with a relatively large female are less likely to be infanticidal than are those with a relatively small female. These data suggest that males are subordinated after copulation by their mates and that this subordination is a factor in the reduction of infanticide and the initiation of paternal responsiveness.     

Differences in encoding for free recall vs. recognition

Three experiments examined effects of test expectancy on memory for relatively unrelated words. In Experiment I, where preliminary recall or recognition practice was given, both recall and recognition were superior when the subjects expected and had practiced for recall. Free study led to better recall and recognition than paced presentation, but did not interact with test expectancy. Experiment II demonstrated that recall was better for subjects expecting a recall vs. a recognition test in the absence of preliminary practice. In Experiment III all subjects practiced both recall and recognition prior to presentation of the critical list. Study time also was varied. With longer study, recall was better when a recall test was expected, with no test expectancy effect on recognition. There were no appreciable expectancy effects with the short study period. Self-reports and other data suggested that the critical encoding differences produced by test expectancy manipulation were quantitative in nature.     

Computer administration of the Peabody Picture Vocabulary Test to young children

Computer-controlled administration of the Peabody Picture Vocabulary Test to children between the ages of 4 and 13 years was shown to be feasible without the presence of a live examiner. Test-retest correlation coefficients were obtained in the range from .54 to .74 and were not significantly different from those obtained with manual administration in the PPVT standardization sample. Practice effects and IQ differences between the two forms of the test were nonsignificant.     

Can we understand why cognitive function predicts mortality? Results from the Caerphilly Prospective Study (CaPS)

The association between cognitive function and mortality is of increasing interest. We followed 1870 men aged 55–69 years at cognitive assessment for 16 years to establish associations with all case and cause specific mortality. Cognitive assessment included AH4, 4 choice reaction time (used as estimates of mid-life cognition) and the National Adult Reading Test (used as an estimate of early-life cognition). Causal models were tested for the effects of a) early-life cognition, b) confounding through mid-life disease, and c) the effects of sociodemographic and lifestyle factors. A fully adjusted model was also tested. Age adjusted associations with mid-life cognitive function were found with mortality from circulatory, coronary, respiratory and digestive disease but not from cancer mortality. Age adjusted associations were attenuated and in some cases nullified by further adjustment for each of early-life cognition, mid-life disease risk and sociodemographic and lifestyle factors. These associations cannot be assumed to be unbiased estimates of effect due to the complex confounding structures that exist in these data. Future studies should explore natural experiments, use different populations where the confounding structures may be different and evaluate more complex methods that may be able to deal with the inherent complexities of a life course perspective.     

The Disgust Scale: item analysis, factor structure, and suggestions for refinement

In the 4 studies presented (N = 1,939), a converging set of analyses was conducted to evaluate the item adequacy, factor structure, reliability, and validity of the Disgust Scale (DS; J. Haidt, C. McCauley, & P. Rozin, 1994). The results suggest that 7 items (i.e., Items 2, 7, 8, 21, 23, 24, and 25) should be considered for removal from the DS. Secondary to removing the items, exploratory and confirmatory factor analyses revealed that the DS taps 3 dimensions of disgust: Core Disgust, Animal Reminder Disgust, and Contamination-Based Disgust. Women scored higher than men on the 3 disgust dimensions. Structural modeling provided support for the specificity of the 3-factor model, as Core Disgust and Contamination-Based Disgust were significantly predictive of obsessive- compulsive disorder (OCD) concerns, whereas Animal Reminder Disgust was not. Results from a clinical sample indicated that patients with OCD washing concerns scored significantly higher than patients with OCD without washing concerns on both Core Disgust and Contamination-Based Disgust, but not on Animal Reminder Disgust. These findings are discussed in the context of the refinement of the DS to promote a more psychometrically sound assessment of disgust sensitivity.     

The effects of food deprivation,aggression, and isolation on infanticide in the male Mongolian gerbil

Male Mongolian gerbils show an increase in infanticide and pup-cannibalism after 24-hr food deprivation, suggesting that food acquisition is a function of this activity. Dominant animals show high levels of infanticide, but subordinate animals are inhibited from this activity. An increase in infanticide is seen when males from a single sex group are isolated; this increase resembles that observed when a male is separated from his pregnant mate [Elwood, 1980]. These results suggest a mechanism whereby males are normally brought into a noninfanticidal state during cohabitation with their pregnant mates owing to subordination by the latter. In this manner males are able to utilize strange pups as food but avoid harming their own offspring.
