Item-specific processing reduces false memories

We examined the effect of item-specific and relational encoding instructions on false recognition in two experiments in which the DRM paradigm was used (Deese, 1959; Roediger & McDermott, 1995). Type of encoding (item-specific or relational) was manipulated between subjects in Experiment 1 and within subjects in Experiment 2. Decision-based explanations (e.g., the distinctiveness heuristic) predict reductions in false recognition in between-subjects designs, but not in within-subjects designs, because they are conceptualized as global shifts in decision criteria. Memory-based explanations predict reductions in false recognition in both designs, resulting from enhanced recollection of item-specific details. False recognition was reduced following item-specific encoding instructions in both experiments, favoring a memory-based explanation. These results suggest that providing unique cues for the retrieval of individual studied items results in enhanced discrimination between those studied items and critical lures. Conversely, enhancing the similarity of studied items results in poor discrimination among items within a particular list theme. These results are discussed in terms of the item-specific/ relational framework (Hunt & McDaniel, 1993).     

An integrative conceptual framework of disability. New directions for research

Advances in research on disability and rehabilitation are essential to creating equal opportunity, economic self-sufficiency, and full participation for persons with disabilities. Historically, such initiatives have focused on separate and specific areas, including neuroscience, molecular biology and genetics, gerontology, engineering and physical sciences, and social and behavioral sciences. Research on persons with disabilities should examine the broader context and trends of society that affect the total environment of persons with disabilities. This article examines the various disability paradigms across time, assessing the relative contribution of the socioecological perspective in guiding research designed to improve the lives of persons with disabilities. The authors recommend new research directions that include a focus on life span issues, biomedicine, biotechnology, the efficacy and effectiveness of current interventions, an emphasis on consumer-driven investigations within a socioecological perspective of disability, and the implications for research and practice.     

A practice-based exploration of therapeutic change in a charitable,community-based person-centred counselling service using routine outcome measures of anxiety and depression. I: Statistical and clinically significant change

Background

Establishing the value of differing treatments for depression and anxiety is crucial in a climate of delimited spending and increased demand. Drawing from a well-founded, diverse evidence base is salient to constructive evaluation and any subsequent recommendations being fit for purpose.

Design

This study employed a practice-based quantitative design to explore therapeutic gains in adult counselling clients attending person-centred therapy (n = 301), delivered in a charitable, community-based UK service.

Measures

Outcome measures PHQ-9 and GAD-7 were used from three time points: initial assessment (IA), first ongoing session and last or 6th ongoing appointment (whichever occurred first; T1, T2 and T3).

Analysis

Repeated measures ANOVA, CSI, RI and RCSI calculations were used to consider significant change in clients.

Findings

Reductions in PHQ-9 and GAD-7 outcome measures were observed over time (between T2 & T3 and T1 & T3) and were all statistically significant (p = <0.001). By T3: CSI was achieved by 48.1% of clients on PHQ-9 and 50.8% of clients on GAD-7, RI was achieved by 47.8% of clients on PHQ-9 and 60.5% of clients on GAD-7, and RCSI was achieved by 32.6% of clients on PHQ-9 and 41.2% of clients on GAD-7.

Conclusions

The treatment observed resulted in effective outcomes equivalent to other therapies reviewed in the literature for clients' symptoms of anxiety and depression as measured by GAD-7 and PHQ-9.     

Integrating the ethical and social context of computing into the computer science curriculum

This paper describes the major components of ImpactCS, a program to develop strategies and curriculum materials for integrating social and ethical considerations into the computer science curriculum. It presents, in particular, the content recommendations of a subcommittee of ImpactCS; and it illustrates the interdisciplinary nature of the field, drawing upon concepts from computer science, sociology, philosophy, psychology, history and economics.     

Intelligence and changes in regional cerebral glucose metabolic rate following learning

Positron emission tomography (PET) studies of brain glucose metabolic rate (GMR) in normal volunteers report inverse correlations between GMR and scores on the Raven's Advanced Progressive Matrices (RAPM) and verbal fluency. A new study in eight normal men reports widespread significant GMR decreases following learning a complex task (the computer game “Tetris”). The purpose of this study is to ascertain the correlations between GMR changes following learning “Tetris” and psychometric intelligence scores (RAPM and WAIS-R) to determine whether high-ability subjects show the largest GMR decreases, as predicted by a brain efficiency hypothesis. This hypothesis is supported with significant correlations between the magnitude of GMR change and intelligence scores in many brain areas that changed with learning. Some implications for the role of attention, memory, and speed of processing are discussed in view of the specific brain areas involved.     

Analyzing Individual Status and Change with Hierarchical Linear Models:Illustration with Depression in College Students

ABSTRACT A recently developed class of multilevel or hierarchical linear models (HLM) provides an intuitive and efficient way to estimate individual growth or change curves. The approach also models the between-subjects variation of the individual change curves with treatment factors and individual attributes. Unlike other repeated measures analysis methods common in the behavioral sciences, HLM allows the fit of data with unequal numbers of repeated observations for each subject, variable timing of observations, and missing data, features which are often characteristic of data from field studies. The application of HLM for the analysis of repeated psychological measures is discussed and illustrated here with depression data for college students. Strengths and limitations of the approach are discussed.     

Aiding the parolee adjustment process: A systemic perspective on assessment

Addressing the mental health needs of inmates and parolees is a complex process. The authors have found a family systems approach useful in conceptualizing the complexities of the adjustment process faced by parolees. The inmate/parolee is embedded in a number of complex systems that present difficulties related to boundary maintenance, hierarchy struggles, and family-of-origin loyalties. The authors suggest crucial areas for assessment and some common dysfunctional systems dynamics that are encountered.     

Descartes on Hatred

This paper examines Descartes’ account of hatred. Descartes holds that individuals should not hate, because hatred separates us from goods, causes sadness, and produces vicious character traits. Although some scholars argue that hatred is necessary to protect the body, I argue that Descartes holds that hatred is not necessary to protect the body, because there are other means of protecting the body that do not involve hatred. I conclude this paper by showing the place of hatred in Descartes’ broader moral theory, especially his emphasis on the wellbeing of the soul and the virtue of generosity.
