Response bias,recollection, and familiarity in individuals with Highly Superior Autobiographical Memory (HSAM)

ABSTRACT

The current study focused on individuals with Highly Superior Autobiographical Memory (HSAM) and had two main objectives: 1) investigate whether HSAMs have increased recollection performance compared to controls, and 2) investigate whether HSAMs have a reliably different response bias than controls. While previous lab-based recognition tests have shown that HSAMs have normal memory performance, these tests were based on a mixture of both recollection and familiarity. Here, we employed recognition tests specifically designed to separate recollected responses from those based on familiarity. Additionally, we were interested in how HSAMs make their memory decisions. Several studies have shown a great deal of variability between individuals in their response bias. Here, individuals with HSAM and age- matched controls completed a remember/know and a source memory test. HSAMs behaved like controls in both overall and recollection-based memory discrimination. However, HSAMs showed a significantly more liberal response bias, endorsing more items as “old” than controls. These findings contribute to our understanding of how memory processes – especially those related to decision-making – function in those with superior memory abilities and may help elucidate how other (non-HSAM) memory experts make decisions.     

Crosswords to Computers: A Critical Review of Popular Approaches to Cognitive Enhancement

Cognitive enhancement strategies have gained recent popularity and have the potential to benefit clinical and non-clinical populations. As technology advances and the number of cognitively healthy adults seeking methods of improving or preserving cognitive functioning grows, the role of electronic (e.g., computer and video game based) cognitive training becomes more relevant and warrants greater scientific scrutiny. This paper serves as a critical review of empirical evaluations of publically available electronic cognitive training programs. Many studies have found that electronic training approaches result in significant improvements in trained cognitive tasks. Fewer studies have demonstrated improvements in untrained tasks within the trained cognitive domain, non-trained cognitive domains, or on measures of everyday function. Successful cognitive training programs will elicit effects that generalize to untrained, practical tasks for extended periods of time. Unfortunately, many studies of electronic cognitive training programs are hindered by methodological limitations such as lack of an adequate control group, long-term follow-up and ecologically valid outcome measures. Despite these limitations, evidence suggests that computerized cognitive training has the potential to positively impact one’s sense of social connectivity and self-efficacy.     

Efficacy of Cognitive Rehabilitation Therapies for Mild Cognitive Impairment (MCI) in Older Adults: Working Toward a Theoretical Model and Evidence-Based Interventions

To evaluate the efficacy of cognitive rehabilitation therapies (CRTs) for mild cognitive impairment (MCI). Our review revealed a need for evidence-based treatments for MCI and a lack of a theoretical rehabilitation model to guide the development and evaluation of these interventions. We have thus proposed a theoretical rehabilitation model of MCI that yields key intervention targets–cognitive compromise, functional compromise, neuropsychiatric symptoms, and modifiable risk and protective factors known to be associated with MCI and dementia. Our model additionally defines specific cognitive rehabilitation approaches that may directly or indirectly target key outcomes–restorative cognitive training, compensatory cognitive training, lifestyle interventions, and psychotherapeutic techniques. Fourteen randomized controlled trials met inclusion criteria and were reviewed. Studies markedly varied in terms of intervention approaches and selected outcome measures and were frequently hampered by design limitations. The bulk of the evidence suggested that CRTs can change targeted behaviors in individuals with MCI and that CRTs are associated with improvements in objective cognitive performance, but the pattern of effects on specific cognitive domains was inconsistent across studies. Other important outcomes (i.e., daily functioning, quality of life, neuropsychiatric symptom severity) were infrequently assessed across studies. Few studies evaluated long-term outcomes or the impact of CRTs on conversion rates from MCI to dementia or normal cognition. Overall, results from trials are promising but inconclusive. Additional well-designed and adequately powered trials are warranted and required before CRTs for MCI can be considered evidence-based.     

Negotiating Gender and Sexuality: A Qualitative Study of Elite Women Boxer Intersecting Identities and Sport Psychology Implications

There is a lack of research on the social construction of gender and sexuality in elite women's boxing and the social psychological implications. Building on research that theorizes gender and sexuality as intersecting identities, this study explored elite women boxers' (n = 10) identities in relation to inclusion and marginalization on the Canadian National Boxing Team. Constructionist thematic analysis identified a central theme, “boxing as empowering and constraining,” encompassing multiple meanings of gendered identities related to physicality and sexualities. These were tied to inclusion and exclusion. Sport psychology recommendations are made for facilitating sport climates that encourage intersecting identity expression.     

Developing Praxis: Mobilising Critical Race Theory in Community Cultural Development

Race remains a significant issue in the lives of many people in Australia. For example, Indigenous Australians lives continue to be marked by social and economic disadvantage and everyday experiences of exclusion. Within this context, the Community Arts Network Western Australia promote social change and the empowerment of Indigenous groups through community cultural development. With an emphasis on community strengths and resources, community arts practice is employed to create, promote, and improve opportunities for participation, network development and empowerment. In this article, we explore these projects from a community psychology orientation, which is committed to developing opportunities for inclusion and also exposing the workings of power in everyday settings. Although there have been many positive outcomes that have resulted from the different activities with communities, there have also been significant barriers to transformative practice, in particular, issues of racialisation and continuing colonisation. We discuss our efforts aimed at understanding racism, which have included engaging with critical race theory and whiteness studies within the context of Indigenous and non‐Indigenous partnerships for change.

More than One Way to be Happy: A Typology of Marital Happiness

This study utilized observational and self‐report data from 57 happily married couples to explore assumptions regarding marital happiness. Suggesting that happily married couples are not a homogeneous group, cluster analyses revealed the existence of three types of couples based on their observed behaviors in a problem‐solving task: (1) mutually engaged couples (characterized by both spouses' higher negative and positive problem‐solving); (2) mutually supportive couples (characterized by both spouses' higher positivity and support); and (3) wife compensation couples (characterized by high wife positivity). Although couples in all three clusters were equally happy with and committed to their marriages, these clusters were differentially associated with spouses' evaluations of their marriage. Spouses in the mutually supportive cluster reported greater intimacy and maintenance and less conflict and ambivalence, although this was more consistently the case in comparison to the wife compensation cluster, as opposed to the mutually engaged cluster. The implications of these typologies are discussed as they pertain to efforts on the part of both practitioners to promote marital happiness and repair marital relations when couples are faced with difficulties.     

Rorschach Responses in Healthy,Community Dwelling Older Adults

Five predicted relationships between age and intellectual level and 16 Rorschach variables were examined through a cross-sectional analysis of 47 healthy, community-dwelling elderly men and women. Subjects were compared by age and intellectual level using gender, level of medication, and scores on the Geriatric Depression Scale (GDS) and the Geriatric Social Readjustment Questionnaire (GSRQ) as covariates. Screening tests for psychiatric and physical illness, recent life events, and hearing and vision loss were administered, In contrast to prior research suggesting changes in Rorschach scores with differences in age and intellectual level, only one significant difference was found for these variables. The data suggest that age and intellectual level may contribute less to Rorschach responses than was previously thought.     

National Trends in Prayer Use as a Coping Mechanism for Depression: Changes from 2002 to 2007

To analyze national trends in the use of prayer among individuals with depression, we adopted a cross-sectional design with data from the adult Alternative Medicine supplement of the National Health Interview Survey 2002 and 2007. Prayer use and depression were combined into 4 categories: (a) prayed in the past 12 months and depressed; (b) prayed in the past 12 months and not depressed; (c) never prayed but depressed; and (d) never prayed and not depressed. Chi-square tests and multinomial logistic regressions were performed to analyze group differences. All analyses were adjusted for the complex sample design and conducted in SAS-callable SUDAAN. Use of prayer for depression was steady at 6.9 % across time; however, general prayer increased significantly between 2002 and 2007 (40.2 vs. 45.7). Women, aged 50–64, unmarried, with high school education were more likely to use prayer while depressed compared to those who were neither depressed nor prayed. Lifestyle behaviors (e.g. alcohol, smoking, exercise) were also associated with prayer use and depression. Prayer use for depression remained steady with unique relationships occurring among those who smoke, use alcohol, and have irregular exercise. Individuals’ use of prayer as a potential complementary treatment for depression suggests that it is critical for mental and physical health treatment providers to be aware of the use of prayer as a coping resource.     

Psychopathic traits and men’s anger response to interpersonal conflict: A pilot study

Psychopathy is associated with emotional dysfunction that impedes the experience of emotions such as fear and sadness and has been purported to facilitate violent behavior. However, findings relative to the association between psychopathy and anger have not been reliably substantiated. Theorists have proposed that psychopathy predisposes one to experience greater frustration and anger, whereas other experts have suggested that there is no convincing evidence for this assertion. In the present study, we tested the relationship between psychopathy subfactors and anger subsequent to conflict or non-conflict interactions. Sixty-eight collegiate-men completed the Self-Report Psychopathy Scale and read vignettes depicting either a conflict or non-conflict scenario and were asked to imagine themselves in the situation. Following presentation of the vignettes, participants completed a lexical-decision-task assessing affective states. Results indicated that the psychopathy subfactors demonstrated strong differential associations, where Factor 1 showed negative and Factor 2 showed positive association with anger activation in response to interpersonal conflict. Findings are discussed in terms of the importance of anger as a facilitator of violence in some psychopathic individuals.
