Variations in recollection: the effects of complexity on source recognition

Whether recollection is a threshold or signal detection process is highly controversial, and the controversy has centered in part on the shape of receiver operating characteristics (ROCs) and z-transformed ROCs (zROCs). U-shaped zROCs observed in tests thought to rely heavily on recollection, such as source memory tests, have provided evidence in favor of the threshold assumption, but zROCs are not always as U-shaped as threshold theory predicts. Source zROCs have been shown to become more linear when the contribution of familiarity to source discriminations is increased, and this may account for the existing results. However, another way in which source zROCs may become more linear is if the recollection threshold begins to break down and recollection becomes more graded and Gaussian. We tested the "graded recollection" account in the current study. We found that increasing stimulus complexity (i.e., changing from single words to sentences) or increasing source complexity (i.e., changing the sources from audio to videos of speakers) resulted in flatter source zROCs. In addition, conditions expected to reduce recollection (i.e., divided attention and amnesia) had comparable effects on source memory in simple and complex conditions, suggesting that differences between simple and complex conditions were due to differences in the nature of recollection, rather than differences in the utility of familiarity. The results suggest that under conditions of high complexity, recollection can appear more graded, and it can produce curved ROCs. The results have implications for measurement models and for current theories of recognition memory.     

Accuracy of Reported Family History and Effectiveness of Medical Record Requests in Genetic Counseling for Alzheimer Disease

The University of British Columbia Hospital Clinic for Alzheimer Disease and Related Disorders (UBCH-CARD) invests significant effort to obtain medical records for the confirmation of patient–reported family histories of dementia. The effectiveness of requesting these records was assessed through a review of the 275 requests made by UBCH-CARD genetic counselors during the 24-month period of January 1, 2005–December 31, 2006. The results were categorized according to outcome. Useful medical records were obtained from 92 (33.5%) requests: 77 (28%) records supported, and 15 (5.5%) records did not support, the patient–reported information. An additional 20 (7.5%) requests yielded only vague information. When verification was possible, patient–reported family histories of Alzheimer disease, dementia, or memory loss were accurate in 84% of cases. During the study period, almost 500 h of genetic counselor work time was spent obtaining, reviewing, and following-up on records received. Changes made to UBCH-CARD procedure in response to these findings are discussed.     

Contextual influences on acculturation processes: The roles of family,community and society

The paper outlines the major approaches to the psychological study of acculturation, drawing particular attention to the importance of context. Three significant contexts are highlighted: family, ethnic community, and society/nation. New perspectives from our evolving program of acculturation research are introduced to illustrate contextual influences on acculturation, and future directions for empirical work are recommended.     

Long-term perceptual specificity effects in recognition memory: the transformed pictures paradigm.

The effects of a study/test mismatch in the viewing mode of natural scenes on recognition memory performance were examined. At both encoding and retrieval, scenes were presented either by being divided into quarters that were displayed in a sequential cumulative fashion or by scrolling the images through the screen, thereby gradually revealing the content of the images. Half of the participants were tested immediately after encoding and the other half after 48 hours. For both the immediate and delayed retrieval conditions, better recognition memory was demonstrated when viewing modes matched across study and test than when they mismatched. Implications for current processing and multiple systems views of memory are discussed.     

Social representations of history in Malaysia and Singapore: On the relationship between national and ethnic identity

Social representations of history were investigated using surveys among university populations of ethnic Malays, Chinese, and Indians in Singapore and Malaysia. Representations of history and historical leaders tended to be hegemonic or consensual, showing low levels of conflict across ethnicity and nationality, even regarding the separation of these two nations. Tendencies towards in-group favoritism and ontogeny were slight, but statistically significant on some measures. National and ethnic identity were positively correlated, with ethnic identity stronger than national identity in Malaysia, and strongest among Malays in Malaysia. National identity was strongest among Chinese in Malaysia, followed by Chinese in Singapore. Results of regression analyses on national identity suggest that ethnicity is more sensitive in Malaysia than in Singapore. Results are interpreted through the frameworks provided by social representations theory and social identity theory. It is argued that hegemonic representations of history are associated with positive correlations between national and ethnic identity.     

Resilience-Based Intervention with Underserved Children: Impact on Self-Regulation in a Randomized Clinical Trial in Schools

Resilience and emotion regulation are crucial for optimal psychosocial functioning in children. This study assessed whether a group-based intervention, the Resilience Builder Program (RBP), improved student report of emotion regulation when administered in elementary schools. Sixty-seven students aged 9–12 years (M = 10.50, SD =.74; 82.1% male, 98.5% ethnic/racial minority) were randomly assigned to receive the RBP intervention immediately or following a semester delay. Participants reported their emotional control using the How I Feel scale. Students who received the RBP reported a significant increase in their emotional control and a significant decrease in negative emotion compared to those students in the delayed treatment sample who had not yet received the intervention. Further, students indicated a strongly positive perception of the therapy.     

Substance Use Research with Indigenous Communities: Exploring and Extending Foundational Principles of Community Psychology

Many Indigenous communities are concerned with substance use (SU) problems and eager to advance effective solutions for their prevention and treatment. Yet these communities also are concerned about the perpetuation of colonizing, disorder‐focused, stigmatizing approaches to mental health, and social narratives related to SU problems. Foundational principles of community psychology—ecological perspectives, empowerment, sociocultural competence, community inclusion and partnership, and reflective practice—provide useful frameworks for informing ethical community‐based research pertaining to SU problems conducted with and by Indigenous communities. These principles are explored and extended for Indigenous community contexts through themes generated from seven collaborative studies focused on understanding, preventing, and treating SU problems. These studies are generated from research teams working with Indigenous communities across the United States and Canada—inclusive of urban, rural, and reservation/reserve populations as well as adult and youth participants. Shared themes indicate that Indigenous SU research reflects community psychology principles, as an outgrowth of research agendas and processes that are increasingly guided by Indigenous communities. At the same time, this research challenges these principles in important ways pertaining to Indigenous–settler relations and Indigenous‐specific considerations. We discuss these challenges and recommend greater synergy between community psychology and Indigenous research.     

An Ethical Imperative: Effectively Reducing SGM Disparities Utilizing a Multi-Level Intervention Approach

Health disparities for sexual and gender minority (SGM) populations are well documented and manifest systemically. Mental health professionals have begun working to address these disparities, demonstrating efforts to more effectively define and increase competency in SGM health and by adapting existing evidence-based interventions to more effectively target the unique needs of the SGM community. While such efforts are necessary, they inadequately address the systemic nature of the problem, placing an unnecessary burden on SGM individuals to tolerate systemic discrimination, injustice, and inequality. The current special series attempts to address this gap by featuring papers that describe multilevel (e.g., micro, mezzo, macro) intervention approaches to reduce SGM health disparities. We argue that advocacy is inherent to the work, and we hope that this special series will empower mental health professionals to engage in multilevel, systemic interventions as an ethical imperative.     

A feminist psychotherapeutic approach to working with women who eat compulsively1

Feminist psychoanalytic theorists argue that eating problems demonstrate ways in which conscious and unconscious gendered feelings about women are split off and projected on to their bodies. As such, they are complex ways in which women attempt to negotiate and express their identities within their paradoxical social position in contemporary western society. They are not just consumers but also objects of consumption. This paper explores material from a feminist psychodynamic therapy group for women with a variety of eating problems, focusing on how interweaving both discursive and unconscious approaches to understanding the gendered function of weight can facilitate change. Feminist psychodynamic therapists work with the concept that the body is an interface between conscious and unconscious mind within both an internal and a social world. This framework enables the client to understand the connections between socially constructed frameworks of femininity, emotions and bodily sensations, rather than to act on them through some form of bodily abuse. This approach is based on my adaptation of Susie Orbach's (1978) ‘Fat is a Feminist Issue’ therapeutic model for working with compulsive eaters. While arguing that a feminist psychoanalytic framework is crucial in this type of work, I suggest that it is essential to combine this with cognitive and behavioural therapeutic interventions in order to provide a pedagogic structure in which food, eating and body size come to be seen as meaningful.
