Young infants reach correctly in A-not-B tasks: on the development of stability and perseveration

This paper examines the development of perseverative reaching in the A-not-B task. We describe two recent models that view perseveration as a sign of developmental progress toward stability. In Experiment 1, we test the novel prediction from both models that very young infants should not perseverate in the A-not-B task whereas older infants should. We tracked infants' behavior monthly on the A-not-B task and found that infants reached correctly at 5 months, and only perseverated at 7 and 8 months of age. Experiment 2 provides further evidence on the role of motor development in the emergence of perseveration by exploring the connection between perseveration and detailed changes in reach kinematics in two infants across the first year. These data together suggest that perseveration is a sign of developmental achievement on the path to stable and flexible behavior.     

Immobility and supination in garter snakes (Thamnophis elegans) following handling by human predators

A common response of animals to physical restraint is tonic immobility. The authors observed the behavior of garter snakes, Thamnophis elegans, in the field to determine the frequency of immobility as a response to handling. Most snakes fled after release, but the remainder remained immobile, sometimes on their backs (supination), for up to 10 min. Immobility was seen most often in pregnant snakes, which also were more likely than other snakes not to have moved before capture. Failure to move, either before or after capture, might be a consequence of the limited locomotory ability of gravid snakes. However, the lack of observations of interactions between snakes and their natural predators impedes researchers' understanding of the antipredator value, if any, of tonic immobility.     

Stigma as ego depletion: how being the target of prejudice affects self-control

This research examined whether stigma diminishes people's ability to control their behaviors. Because coping with stigma requires self-regulation, and self-regulation is a limited-capacity resource, we predicted that individuals belonging to stigmatized groups are less able to regulate their own behavior when they become conscious of their stigmatizing status or enter threatening environments. Study 1 uncovered a correlation between stigma sensitivity and self-regulation; the more Black college students were sensitive to prejudice, the less self-control they reported having. By experimentally activating stigma, Studies 2 and 3 provided causal evidence for stigma's ego-depleting qualities: When their stigma was activated, stigmatized participants (Black students and females) showed impaired self-control in two very different domains (attentional and physical self-regulation). These results suggest that (a) stigma is ego depleting and (b) coping with it can weaken the ability to control and regulate one's behaviors in domains unrelated to the stigma.     

Defensive projection, superimposed on simplistic object relations, erodes patient-provider relationships in high-risk pregnancy: an empirical investigation

In an attempt to illustrate the relevance of psychoanalytic theory and research to behavior medicine, an empirical investigation was conducted of females treated at a high-risk pregnancy specialty clinic (N = 58). Drawing from psychoanalytic object relations theory, it was hypothesized and confirmed that use of projection as a defense mechanism during pregnancy, superimposed on simplistic object relations, predicted an erosion of patient-provider relationships during the pregnancy/postdelivery period. Findings are interpreted through the perspective of mentalization, pertaining to individuals' ability to understand the mental states of self and others, specifically under significant stress. Implications for psychoanalytically oriented assessment and treatment, and for the rift between psychoanalysis and research, are discussed.     

Adolescents of the USA National Longitudinal Lesbian Family Study: Can Family Characteristics Counteract the Negative Effects of Stigmatization?

This investigation examines the impact of homophobic stigmatization on the well-being of 17-year-old adolescents who were conceived through donor insemination and whose mothers enrolled before they were born in the largest, longest-running, prospective study of lesbian families, with a 93% retention rate to date. The data for the current report were collected through questionnaires completed by the adolescents and their mothers. The adolescents (39 girls and 39 boys) were queried about family connection and compatibility. They were also asked to indicate if they had experienced discrimination based on their mothers' sexual orientation. Adolescent well-being was assessed through the parental report of the Child Behavior Checklist/6-18. Forty-one percent of the adolescents had experienced stigmatization based on homophobia. Hierarchical, multiple-regression analyses revealed that stigmatization was associated with more problem behavior in these adolescents, but that family compatibility neutralized this negative influence. The results indicate that adolescents who have close, positive relationships with their lesbian mothers demonstrate resilience in response to stigmatization.     

Life satisfaction in chronic pain patients: the stress-buffering role of the centrality of religion

Chronic pain (CP) is a stressful condition that severely impacts individuals' lives. Researchers have begun to explore the role of religion for CP patients, but the literature is scarce, especially for West European populations. Drawing from the transactional theory of stress, this study examined the associations between the religious meaning system and the life satisfaction for a group of CP patients who were members of a Flemish patients' association. To take into account the religious landscape of West European countries, the centrality of one's religious meaning system, rather than religious content, was the focus. Results from the questionnaires completed by 207 patients suggest that the centrality of a meaning system is an important factor in the promotion of life satisfaction for this group, above and beyond the influence of several control variables. Furthermore, the centrality of the religious meaning system moderated or buffered the detrimental influence of pain severity on life satisfaction.     

Toward a better understanding of the justice judgment process: The influence of fair and unfair events on state justice sensitivity

People differ in the way they regard justice. Although some people may be relatively unaffected by justice issues, many others regard justice as a very important concept and react to it accordingly. Prior research suggests that this sensitivity to justice is a stable personality trait. In three studies, we show that (compared to neutral events) experiencing just and unjust events (directed toward the self or others) can elevate state levels of justice sensitivity. We discuss the implications of these findings, including the notion how these results can lead to a better understanding of the justice judgment process.

Learning fine-grained and category information in navigable real-world space

Spatial judgments are affected by both fine-grained and categorical knowledge. We investigated whether, and how, the two forms of knowledge are learned in real-world, navigable space, as well as the time course of learning each type of knowledge. Participants were Northwestern University undergraduates who estimated the locations of buildings and other landmarks on campus. The Northwestern campus is roughly divided into three regions whose borders are not easy to discern, either from a map or by navigation. Nevertheless, students often refer to these regions linguistically and use them when making housing decisions, choosing classes, and so forth. We found that knowledge of both the fine-grained configuration of locations and the regional distinctions increased with time. However, regional influences on judgments occurred later in students’ time on campus. Consequently, computed distances across the nonexistent border between north and south campus locations became more biased with time. The results have implications for understanding how spatial representations develop in navigable environments.     

Religious Involvement among Caribbean Blacks in the United States

This study examined demographic and denominational differences in religious involvement (i.e., organizational, non-organizational, subjective) among Caribbean Blacks (Black Caribbeans) residing in the U.S. using data from the National Survey of American Life. Caribbean Blacks who were born in the U.S. had lower levels of religious involvement than those who immigrated and respondents originating from Haiti (as compared to Jamaica) had higher levels of religious involvement, while persons from Trinidad-Tobago reported lower service attendance than did Jamaicans. Older persons, women and married persons generally demonstrated greater religious involvement than their counterparts, while highly educated respondents expressed lower levels of self-rated religiosity. Denominational differences indicated that Baptists reported high levels of religious involvement; however, in several cases, Pentecostals and Seventh Day Adventists reported greater involvement.
