Two-and-a-Half-Year-Olds’ Memory for Sources of Actions: Contextual Support Facilitates Recall

This research examines the early emergence of source-monitoring abilities. Previous research has consistently demonstrated that children as young as 3 to 4 years of age do well on simple versions of action-based source-monitoring tasks. Research on even younger children, however, remains lacking. In this study we examined whether 2½-year-olds could accurately recall source on a simplified task. For the procedure, we used an action-based task in which children collaborate with an experimenter to build a model farm. During construction, the child and the experimenter took turns placing items on the farm. After construction, children were administered a source memory test in which they were asked to recall who had placed each item. To more closely examine factors that influence source accuracy in this young population, we included two conditions that varied in terms of contextual support. In the no-context-cues condition, in line with typical source-monitoring tasks, children were asked the source test question while items were presented individually and the farm was not in view. In the context-cues condition, the original spatial array of farm items was left intact to provide additional cues for children's source decisions. The main finding was that children in both conditions showed high levels of source accuracy at test indicating a surprisingly early age of emergence for this ability. Also, as predicted, children in the context-cues condition were the most accurate in attributing source.     

Faith-Based Organizations: Sexual Harassment and Health in Accra-Tema Metropolis

Sexual harassment occurs frequently in many faith-based organizations (FBOs). This study investigated whether sexual harassment in FBOs was a public health concern in Ghana. A cross-sectional exploratory approach was used to assess the prevalence and incidence of traditional or contrapower sexual harassment in FBOs. We also investigated the correlation between sexual harassment and health. Respondents completed a self-administered open-ended questionnaire in an anonymous survey about sexual harassment during the 12 months preceding the study. We hypothesized that both traditional and contrapower harassment were prevalent in FBOs of Ghana and also that the health effects were the same for both sexes in both forms of harassment. The two hypotheses were generally supported. We found that sexual harassment is a public health concern. Women were more likely to be sexually harassed (73%) than men were (27%). Sexual harassment negatively affects the victims’ health outcome. Secondly, both the traditional and contrapower forms of sexual harassment were prevalent in FBOs in Ghana. The health consequences of sexual harassment in Ghana are the same as in an industrialized country. The implications for policy and research are discussed.     

Positive and negative affect,depression, and cognitive processes in the Cognition in the Study of Tamoxifen and Raloxifene (Co-STAR) Trial

ABSTRACT

Objectives: This study examined the relationship between positive and negative affect, depressive symptoms, and cognitive performance. Methods: The sample consisted of 1479 non-demented, postmenopausal women (mean age = 67 years) at increased risk of breast cancer enrolled in the National Surgical Adjuvant Breast and Bowel Project’s Study of Tamoxifen and Raloxifene. At each annual visit, women completed a standardized neuropsychological battery and self-report measures of affect and depression. Data from three visits were used in linear mixed models for repeated measures using likelihood ratio tests. Separate analyses were performed to relate positive/negative affect and depression to each cognitive measure. Results: Higher positive affect was associated with better letter fluency (p = .006) and category fluency (p < .0001). Higher negative affect was associated with worse global cognitive function (p < .0001), verbal memory (CVLT List B; p = .002), and spatial ability (p < .0001). Depressive symptoms were negatively associated with verbal knowledge (p = .004), figural memory (p < .0001), and verbal memory (p’s ≤ .0001). Discussion: Findings are consistent with some prior research demonstrating a link between positive affect and increased verbal fluency and between depressive symptoms and decreased memory. The most novel finding shows that negative affect is related to decreased global cognition and visuospatial ability. Overall, this research in a large, longitudinal sample supports the notion that positive affect is related to increases and negative affect to decreases in performance on distinct cognitive measures.     

The place of words and numbers in psychiatric research

In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics. Relationships between these objects of study can in turn be explored in three different ways: 1/ by a hermeneutic process, 2/ using statistics, the most frequent method in psychiatric research today, 3/ using equations, i.e. using mathematical relationships that are formal and deterministic. The 3 ways of representing entities (with language, locally with mathematics or globally with mathematics) and the 3 ways of expressing the relationships between entities (using hermeneutics, statistics or equations) can be combined in a cross-tabulation, and nearly all nine combinations can be described using examples. A typology of this nature may be useful in assessing which epistemological perspectives are currently dominant in a constantly evolving field such as psychiatry, and which other perspectives still need to be developed. It also contributes to undermining the overly simplistic and counterproductive beliefs that accompany the assumption of a Manichean “quantitative/qualitative” dichotomy. Systematic examination of this set of typologies could be useful in indicating new directions for future research beyond the quantitative/qualitative divide.     

Hippocampal and neocortical contributions to memory: advances in the complementary learning systems framework

The complementary learning systems framework provides a simple set of principles, derived from converging biological, psychological and computational constraints, for understanding the differential contributions of the neocortex and hippocampus to learning and memory. The central principles are that the neocortex has a low learning rate and uses overlapping distributed representations to extract the general statistical structure of the environment, whereas the hippocampus learns rapidly using separated representations to encode the details of specific events while minimizing interference. In recent years, we have instantiated these principles in working computational models, and have used these models to address human and animal learning and memory findings, across a wide range of domains and paradigms. Here, we review a few representative applications of our models, focusing on two domains: recognition memory and animal learning in the fear-conditioning paradigm. In both domains, the models have generated novel predictions that have been tested and confirmed.     

Career metaphors and their application in theory and counseling practice

This article, first given as an address to the January 2002 National Consultation on Career Development, Ottawa, Ontario, draws attention to the inevitability of metaphor in human thought, discourse, and theory, including that concerning careers. The article (a) explores the benefits and the dangers of metaphorical thinking and advocates the use of “multiple metaphor” as a means of understanding careers; (b) looks particularly at metaphors in the context of new, more flexible careers; (c) introduces 10 archetypal career metaphors; and (d) considers how career counseling practice can be assisted through the facilitation of metaphorical thinking.     

the experience of unemployment for fishery workers in newfoundland: what helps and hinders

In this exploratory research study, the unemployment experience of people involved in the fishery and living in the outports of Newfoundland and Labrador was explored. Fifty‐three critical incident interviews were conducted by community outreach workers. These interviews yielded important information about the factors that facilitated or hindered the unemployment experience. In interpreting the results, both the general literature on unemployment as well as the special contextual aspects of the situation were explored.     

Coping and psychological distress for men with substance use disorders

Coping with stress is a major focus for chemically dependent persons in relapse prevention programs. The relationships among coping and psychological distress were investigated in 71 men with substance use disorders, at both pre—and post-treatment. It was predicted that low task-oriented coping, high emotion-oriented coping, and high avoidance-oriented coping would predict psychological distress (e.g., anxiety and depression). It was also expected that use of task-oriented coping would increase following treatment and that use of emotion-oriented coping and avoidance-oriented coping, and reported levels of psychological distress would all decrease following treatment. Participants completed the Coping Inventory for Stressful Situations and the General Health Questionnaire, took part in an intensive treatment program (e.g., relaxation, drug education, stress management) and completed these questionnaires again following treatment. Results indicated that high emotion-oriented coping predicted hypochondriasis, anxiety and depression. Task-oriented and avoidance-oriented coping did not predict psychological distress, although task-oriented coping was negatively related to hypochondriasis, anxiety and depression. The results regarding change in coping styles and levels of psychological distress were as hypothesized, except that avoidance-oriented coping did not significantly change following treatment. Theoretical and practical implications of the research are discussed.
