An analysis of response,direction, and place learning in an open field and T maze

Rats were trained to locate food in a response, direction, or place problem on an open field located at 2 positions. In Experiment 1, both the response and direction groups solved the problem. The place group failed to solve the task in approximately 300 trials. Experiment 2 demonstrated that rats need distinguishable start points to solve a place problem when neither a response nor a direction solution is available. Findings from Experiment 3 suggest that a combination of path traveled and distinct cues help to differentiate start points. Experiment 4 replicated the findings using a T maze. These results suggest "place" solutions are difficult for rats. The data are discussed with respect to conditional learning and modern spatial mapping theory.     

Psychological and Socio-cultural Adjustment during Cross-cultural Transitions: A Comparison of Secondary Students Overseas and at Home

The study further explores the distinction of psychological and socio-cultural adjustment during cross-cultural transitions. One hundred and seventy-eight New Zealand American Field Service (AFS) students residing in 23 different countries completed questionnaires which contained assessments of the following: Personality (extraversion and locus of control); life changes (Social Readjustment Rating Questionnaire); homesickness, cultural distance, acculturation (cultural identity and cultural integration—separation); attitudes toward host country; language ability; amount of contact with host and co-nationals; relationship satisfaction with co-nationals, host nationals and host family; and outcome measures of socio-cultural (social difficulty) and psychological adjustment (Profile of Mood States). Stepwise regressions revealed that homesickness, external locus of control, life changes, and social difficulty accounted for 55% of the variance in psychological adjustment. In contrast, cultural distance, language ability, satisfaction with host national contact, cultural separation and mood disturbance explained 52% of the variance in socio-cultural adaptation. In the second part of the research, psychological and socio-cultural adjustment of AFS students was compared with a sample of 142 home-based New Zealand secondary school students. Although there were no significant differences in psychological adjustment between the two groups, the students who were resident abroad experienced greater socio-cultural difficulties than the students resident in New Zealand (P < 0.0005), and, as hypothesized, the correlation between psychological and socio-cultural adjustment was significantly greater in the home-based students compared to the AFS group (P < 0.0001).     

Novel odors evoke risk assessment and suppress appetitive behaviors in mice

The effects of four novel odors on risk assessment by mice (i. e., flat back approach, stretched attention, immobility) and the suppression of appetitive behaviors were examined in two experiments. When novel odors were presented in a straight runway, subjects spent significantly less time in the odor compartment, relative to controls, when it contained sheep wool, chocolate, or citronella (but not cat fur) odors. Risk assessment behaviors occurred at similar levels among all groups and appetitive behaviors were not suppressed by the novel odors. When odorants were scattered over one half of the subjects' home cage floor in Experiment 2, all novel odors increased the duration of at least on e risk assessment measure and/or suppressed appetitive behaviors (i. e., eating, grooming, rearing). The results clearly reveal that a reasonably wide range of novel odors evoke at least some level of risk assessment which presumably reflects increased fearfulness. The odors of sheep wool and cat fur induced a wider range of such responses than did chocolate or cinnamon suggesting that mammalian odors may be particularly effective stimuli. If so, however, it is clear that predator odors are not uniquely effective in this regard. Experiment 1 also underscores the importance of the testing environment in assessing the behavioral effects of novel odors in mice. © 1993 Wiley-Liss, Inc.     

Best Practices for Counseling Clients Experiencing Poverty: A Grounded Theory

Poverty is a pressing sociopolitical issue in the United States and worldwide. Poverty experiences have a significant effect on one’s mental health and overall wellness. Therefore, the ability to effectively serve clients experiencing poverty is critically important to professional counselors. However, there are no empirical models for counseling clients experiencing poverty. The authors present the results of a constructivist grounded theory study in which 21 professional counselors who work with clients experiencing poverty were interviewed to identify best practices for working with this population. Five major best practices are identified: (a) awareness, (b) training, (c) knowledge, (d) skills, and (e) advocacy. Implications for professional counseling are included.     

Effects of age on estimated familiarity in the process dissociation procedure: The role of noncriterial recollection

Research on recognition memory using the process dissociation procedure has suggested that although recollection (R) declines with age, familiarity (F) remains age invariant. However, this research has used relatively broad definitions of R. An important question concerns age-related changes in memory when R is defined in terms of specific event details. Yonelinas and Jacoby (1996a) required young participants to recollect specific, criterial details of a prior event and found evidence that recollection of noncriterial details elevated estimates of F yet still operated automatically. In the present study, the issue of noncriterial recollection was examined in the context of aging. The results replicated the effects of noncriterial recollection for the young, but not for the older adults, who also showed overall reduced levels of familiarity.     

A contextual change account of the directed forgetting effect

The authors propose that the costs and benefits of directed forgetting in the list method result from an internal context change that occurs between the presentations of 2 lists in response to a "forget" instruction. In Experiment 1 of this study, costs and benefits akin to those found in directed forgetting were obtained in the absence of a forget instruction by a direct manipulation of cognitive context change. Experiment 2 of this study replicated those findings using a different cognitive context manipulation and investigated the effects of context reinstatement at the time of recall. Context reinstatement reduced the memorial costs and benefits of context change in the condition where context had been manipulated and in the standard forget condition. The results are consistent with a context change account of directed forgetting.     

The Children's Attributional Style Interview: Developmental Tests of Cognitive Diathesis-Stress Theories of Depression

This paper presents an initial assessment of the Children's Attributional Style Interview (CASI), a newly designed measure for assessing attributional style in young children (age 5 and up). The CASI was used to conduct prospective tests of the reformulated helplessness (L. Y. Abramson, M. Seligman, & J. Teasdale, 1978) and the integrated hopelessness/self-esteem (G. I. Metalsky, T. E. Joiner, Jr., T. S. Hardin, & L. Y. Abramson, 1993) theories of depression in a sample of 147 5–10-year-old children. For comparison, the same tests were also conducted with the Children's Attributional Style Questionnaire-Revised (CASQ-R; N. J. Kaslow & S. Nolen-Hoeksema, 1991), a commonly used measure for assessing attributional style in older children (age 8 and up). The CASI evidenced support of the reformulated helplessness theory and partial support of the integrated hopelessness/self-esteem theory. The CASI also demonstrated good internal consistency. Thus, our findings provide initial support for the CASI as a methodologically sound measure of attributional style for children as young as 5 years old. Although preliminary, our findings also suggest possible developmental differences in how attributional style interacts with self-esteem and negative life stress. The CASI should prove to be a useful tool in furthering the understanding of the origins and development of attributional style in childhood, as well as its contribution to the understanding of the development and prevention of depressive symptomatology in children.     

At Both Ends of the Gun: Testing the Relationship Between Community Violence Exposure and Youth Violent Behavior

Much psychological inquiry has focused on understanding the contribution that exposure to urban violence makes to violent behavior among youth. However, other ways in which these variables may be related have been largely overlooked. This study compared four alternative social–ecological models of the link between community violence exposure and violent behavior to determine the degree to which (1) community violence exposure contributes to violent behavior, (2) violent behavior contributes to community violence exposure, (3) both are consequences of common antecedents, and (4) both are manifestations of the same higher order construct. Two hundred and seventy-seven adolescent offenders were interviewed about family, neighborhood, cognitive, and peer characteristics, in addition to violent behavior and community violence exposure. Results suggest that a plausible way to understand the association between community violence exposure and youth violent behavior is to consider both as representations of a general involvement in violence.     

Asian social psychology: Looking in and looking out

The present paper examines the role, status and development of Asian social psychology from four perspectives: (i) looking back; (ii) looking in; (iii) looking out; and (iv) looking forward. Looking back elaborates early attempts to 'add Asians' to social psychology and replicate classic social psychological research in Asian contexts. Looking in describes more sophisticated developments in Asian social psychology including the indigenization of theory, methods and measurements. Looking out critically examines the position of Asian social psychology in the international arena and discusses its impact on the discipline more broadly. Finally, looking forward makes some cautious predictions about the future of Asian social psychology in both regional and international spheres.     

Demographic variables, smoking variables, and outcome across five studies.

OBJECTIVE: Intervention effectiveness can potentially be affected by membership in different demographic subgroups (race, ethnicity, gender, age, and education level) or smoking behavior variables (time to first cigarette, longest previous quit attempt, number of attempts in the past year, number of cigarettes, and stage of change). Previous research on these 2 sets of variables has produced mixed results. DESIGN: This secondary data analysis combined data from 5 effectiveness trials (a random-digit-dial sample [N=1,358], members of an HMO [N=207], parents of students recruited for a school-based study [N=347], patients from an insurance provider list [N=535], and employees [N=175]) in which smokers were all proactively recruited from a defined population and all received the same expert system intervention. The intervention produced a consistent 22% to 26% point prevalence cessation rate across the 5 studies. MAIN OUTCOME MEASURES: The main outcome measures were 24-hr point prevalence, 7-day point prevalence, 30-day prolonged abstinence, and 6-month prolonged abstinence. RESULTS: There were no significant differences in outcome across gender, race, and ethnicity subgroups. There were significant differences and small effect sizes for age and education subgroups. There were significant differences and large effect sizes for all 5 smoking behavior variables. DISCUSSION: Demographic variables are static variables, whereas the smoking variables are more dynamic, that is, open to change. Given the dynamic nature of the smoking variables and the large effect sizes, interventions tailored on the smoking variables should be more successful.
