Achievement goals and engagement in individual and collective learning activities

The relationship between achievement goals and individual and collective learning activities was examined for 290 university students who completed two questionnaires. One assessed three achievement goals-a mastery goal and two performance goals, namely, approval seeking and advancing. The other questionnaire measured how actively students report engaging in individual and collective learning activities. Regression analyses showed that the adoption of mastery goals was associated with active engagement in both individual and collective learning, while adoption of a performance goal of approval seeking was associated with passive engagement in individual learning activities. These results are discussed in relation to their theoretical implications and in regard to the possible moderating effect of protecting self-worth.     

Prevention of depression with primary care patients: A randomized controlled trial

The prevention of major depression is an important research goal which deserves increased attention. Depressive symptoms and disorders are particularly common in primary care patients and have a negative impact on functioning and well-being comparable with other major chronic medical conditions. The San Francisco Depression Prevention Research project conducted a randomized, controlled, prevention trial to demonstrate the feasibility of implementing such research in a public sector setting serving low-income, predominantly minority individuals: 150 primary care patients free from depression or other major mental disorders were randomized to an experimental cognitive-behavioral intervention or to a control condition. The experimental intervention group reported a significantly greater reduction in depressive levels. Decline in depressive levels was significantly mediated by decline in the frequency of negative conditions. Group differences in the number of new episodes (incidence) of major depression did not reach significance during the 1-year trial. We conclude that depression prevention trials in public sector primary care settings are feasbile, and that depressive symptoms can be reduced even in low-income, minority populations. To conduct randomized prevention trials that can test effects on incidence with sufficient statistical power, subgroups at greater imminent risk have to be identified.     

Robust tests for multivariate factorial designs under heteroscedasticity

The question of how to analyze several multivariate normal mean vectors when normality and covariance homogeneity assumptions are violated is considered in this article. For the two-way MANOVA layout, we address this problem adapting results presented by Brunner, Dette, and Munk (BDM; 1997) and Vallejo and Ato (modified Brown-Forsythe [MBF]; 2006) in the context of univariate factorial and split-plot designs and a multivariate version of the linear model (MLM) to accommodate heterogeneous data. Furthermore, we compare these procedures with the Welch-James (WJ) approximate degrees of freedom multivariate statistics based on ordinary least squares via Monte Carlo simulation. Our numerical studies show that of the methods evaluated, only the modified versions of the BDM and MBF procedures were robust to violations of underlying assumptions. The MLM approach was only occasionally liberal, and then by only a small amount, whereas the WJ procedure was often liberal if the interactive effects were involved in the design, particularly when the number of dependent variables increased and total sample size was small. On the other hand, it was also found that the MLM procedure was uniformly more powerful than its most direct competitors. The overall success rate was 22.4% for the BDM, 36.3% for the MBF, and 45.0% for the MLM.     

Microswitch technology and contingent stimulation to promote adaptive engagement in persons with minimally conscious state: a case evaluation

This study assessed whether a post-coma woman functioning at the lower end of the minimally conscious state would (a) develop adaptive responding through the use of microswitch technology and contingent stimulation, (b) consolidate and maintain her responding over time, and (c) show evidence of response-consequences awareness (learning and discrimination). The study involved an ABABB¹CB¹ sequence in which the A represented baseline phases, the B and B¹ intervention phases, and the C a control phase with continuous stimulation. Results indicated that the woman developed adaptive responding and consolidated it over the intervention phases of the study. The woman also showed evidence of being aware of response-consequences links. Potential implications and limitations of these findings are discussed.     

Sampling assumptions in inductive generalization

Inductive generalization, where people go beyond the data provided, is a basic cognitive capability, and it underpins theoretical accounts of learning, categorization, and decision making. To complete the inductive leap needed for generalization, people must make a key 'sampling' assumption about how the available data were generated. Previous models have considered two extreme possibilities, known as strong and weak sampling. In strong sampling, data are assumed to have been deliberately generated as positive examples of a concept, whereas in weak sampling, data are assumed to have been generated without any restrictions. We develop a more general account of sampling that allows for an intermediate mixture of these two extremes, and we test its usefulness. In two experiments, we show that most people complete simple one-dimensional generalization tasks in a way that is consistent with their believing in some mixture of strong and weak sampling, but that there are large individual differences in the relative emphasis different people give to each type of sampling. We also show experimentally that the relative emphasis of the mixture is influenced by the structure of the available information. We discuss the psychological meaning of mixing strong and weak sampling, and possible extensions of our modeling approach to richer problems of inductive generalization.     

Vultures as an overlooked model in cognitive ecology

Regional conferences—A capacity‐building mandate: Report on CRCP2011—Building Bridges and Building a Regional Structure

The Caribbean Regional Conference of Psychology was held in Nassau, The Bahamas, from 15 to 18 November 2011, under the auspices of the International Association of Applied Psychology (IAAP), the International Union of Psychological Science (IUPsyS), and the International Association for Cross‐Cultural Psychology (IACCP). The conference was hosted by the Bahamas Psychological Association, and organized by a committee chaired by Dr Ava Thompson, College of the Bahamas. The CRCP2011 attracted over 400 participants from 37 countries, including 20 nations/territories in the Caribbean. A broad scientific program, organized around six conference themes, addressed strengths and challenges to psychology in the region; the current state of psychological research, assessment, and intervention; historical, cultural, and language influences; and links between Caribbean and global models. Conference outcomes included planning for a series of publications to expand on conference themes and presentations, as well as establishment of a steering group to launch a regional organization to support the science and practice of psychology in the Caribbean.     

Contours for a Public Lutheran Theology in the Face of Empire

Abstract : Three themes structure Lutheranism's interpretation of the biblical narrative as it intersects with the present challenges of Empire: justification by faith as a declaration of inclusiveness; God's threefold‐multidimensional action creating and sustaining democratic practices (two kingdoms); and the cross as the critical ‘weapon’ against the ‘glory’ of Empire. This implies placing our theology within the present cultural and religious debate in a way consistent with the methodology of the cross: a theology done from the bowels of Empire, revealing its true face behind its alleged ‘benevolent’ mask.
