A Longitudinal Study of Vocational Maturity and Ethnic Identity Development

This study examines longitudinally the development of vocational maturity and ethnic identity in a majority and a minority group of 641 students in the Province of Québec, Canada. Ethnic identity and four components of vocational maturity were assessed in four cohorts at three times of measurement. Results show clearly different developmental trends in both ethnic identity and in vocational maturity for majority and minority groups: The minority group showed a linear increase in ethnic identity over time, while the majority group showed a decrease starting with the second time of measurement; vocational maturity components showed a more complex pattern of changes but demonstrated that minority participants matured significantly earlier than those from the majority group. There was a positive relationship between ethnic identity and vocational maturity for both groups.     

Continuous Response Monitoring of Relative Time-to-Contact Judgments: Does Effective Information Change During an Approach Event?

In many previous studies of time-to-contact (TTC) judgments of approaching objects, a response was measured after observers viewed the entire event and was used to infer the informational basis for the judgment. Such measures primarily reflect the information used at the end of the approach event and may not reveal whether observers used different information at different times during the event. Evidence indicates that observers use multiple information sources and that the effectiveness of information varies with distance. We introduce a method in which observers continuously report which of 2 approaching objects would reach them first, throughout the approach. We identified the occurrence and time of response reversals. Most observers changed their relative TTC judgments during the event. The pattern of responses indicated that observers did not use tau early during the approach when objects were far and did not use optical size later when the objects were closer. Most observers relied on either optical size or optical expansion rate early during the approach and expansion rate later during the event, although there were individual differences. A single relative TTC judgment measured after observers view an approach event may not reflect judgments or their informational basis throughout the entire event.     

Dyadic Examination of the Influence of Family Relationships on Life Satisfaction at the Empty-Nest Stage

The aim of this study on determinants of life satisfaction in adulthood was to test actor–partner interdependence models among couples in the phase of the family life cycle following the departure of their children from the parental home. Using structural equation modeling, measures of family relationships, such as a person’s own and his/her partner’s marital adjustment, the amount of contact with children (and grandchildren, if applicable), and being a grandparent or not, served as independent variables to predict each partner’s satisfaction with life. A sample comprising 102 couples (of which 58 couples had grandchildren), all at the empty-nest stage, participated in the study. Results revealed that, for both husbands and wives, the effects of their own marital adjustment and the amount of contact with their adult children on their satisfaction with life were significant. A partner effect was also confirmed between wives’ marital adjustment and their husbands’ satisfaction with life. Furthermore, although being a grandparent did not predict higher life satisfaction for the whole sample of couples, the path between the amount of contact with grandchildren and life satisfaction was significant for the subsample of women who were grandmothers. Results are discussed in terms of the needs filled by these family relationships.     

Longitudinal relationships between workplace bullying,basic psychological needs,and employee functioning: a simultaneous investigation of psychological need satisfaction and frustration

The aim of this cross-lagged study was to provide new insight into the interplay between workplace bullying, basic psychological needs (for autonomy, competence, and relatedness), and employee functioning. Based on new developments in self-determination theory (SDT) research, we simultaneously examined the temporal relationships between workplace bullying, need satisfaction and frustration, as well as two indicators of psychological functioning: life satisfaction and psychosomatic complaints. Data were collected at two time points over a 12-month period from a sample of 508 Canadian nurses. Results suggest that bullying not only negatively predicted satisfaction for the needs of autonomy and competence, it actively frustrated all three needs. Frustration of the needs for competence and relatedness as well as satisfaction of the need for relatedness also predicted the psychological functioning of employees exposed to bullying behaviour over time. Taken together, the results suggest that evaluating need frustration provides in-depth insight into the detrimental effects of bullying on employees’ psychological inner resources and may explain the impoverishment of employees’ psychological functioning when confronted with bullying behaviour. The implications for the bullying and SDT literature are discussed.     

Reversal learning in gonadectomized marmosets with and without hormone replacement: are males more sensitive to punishment?

This study examined sex differences in executive function in middle-aged gonadectomized marmosets (Callithrix jacchus) with or without hormonal replacement. We tested ten castrated male (mean age 5.5 years) marmosets treated with testosterone cypionate (T, n = 5) or vehicle (n = 5) on Reversal Learning, which contributes to cognitive flexibility, and the Delayed Response task, measuring working memory. Their performance was compared to that of 11 ovariectomized females (mean age = 3.7 years) treated with Silastic capsules filled with 17-β estradiol (E2, n = 6) or empty capsules (n = 5), previously tested on the same tasks (Lacreuse et al. in J Neuroendocrinol 26:296–309, 2014. doi: 10.1111/jne.12147). Behavioral observations were conducted daily. Females exhibited more locomotor behaviors than males. Males and females did not differ in the number of trials taken to reach criterion on the reversals, but males had significantly longer response latencies, regardless of hormone replacement. They also had a greater number of refusals than females. Additionally, both control and T-treated males, but not females, had slower responses on incorrect trials, suggesting that males were making errors due to distraction, lack of motivation or uncertainty. Furthermore, although both males and females had slower responding following an incorrect compared to a correct trial, the sex difference in response latencies was disproportionally large following an incorrect trial. No sex difference was found in the Delayed Response task. Overall, slower response latencies in males than females during Reversal Learning, especially during and following an incorrect trial, may reflect greater sensitivity to punishment (omission of reward) and greater performance monitoring in males, compared to females. Because these differences occurred in gonadectomized animals and regardless of hormone replacement, they may be organized early in life.
