Does retrieval fluency contribute to the underconfidence-with-practice effect?

Judgments of learning (JOLs) made during multiple study-test trials underestimate increases in recall performance across those trials, an effect that has been dubbed the underconfidence-with-practice (UWP) effect. In 3 experiments, the authors examined the contribution of retrieval fluency to the UWP effect for immediate and delayed JOLs. The UWP effect was demonstrated with reliable underconfidence on Trial 2 occurring for both kinds of JOL. However, in contrast to a retrieval-fluency hypothesis, fine-grained analyses indicated that the reliance of JOLs on retrieval fluency contributed minimally to the UWP effect. Our discussion focuses on the status of the retrieval-fluency hypothesis for the UWP effect.     

Structural and behavioural determinants of immigrant and non-immigrant health status: Results from the Canadian community health survey

The purpose of this paper, which utilizes data from the Canadian Community Health Survey (CCHS-Cycle 1.1), is threefold. The first is to examine the health of Canadian immigrants in relation to non-immigrants, focusing on the relationship between key health determinants and health status. Second, it tests whether these data support the well-documented ‘healthy immigrant effect’. The third is to evaluate the usefulness of using a large national database to study ‘special populations’ such as immigrants. Through a comparison of findings from previous studies, the authors highlight the strengths and weaknesses of different datasets for investigating immigrant health and, by extension, the health of other unique populations in Canada. The present study found that recent arrivals to Canada tended to be substantially healthier than the Canadian-born population. However, this advantage was lost over time, as immigrants with longer residence histories (10 years of residence or longer) tended to have inferior health statuses relative to the Canadian-born. These results indicate that the ‘healthy immigrant effect’ continues to manifest itself in Canada. The findings also suggest that the large sample of immigrants in the CCHS facilitated statistically significant associations between health determinants and health status. This is in contrast to the results of previous studies on immigrant health-such as those using the National Population Health Survey (NPHS)—which reported a number of non-significant and counter-intuitive relationships. We suggest that the CCHS, a comparatively much larger dataset with a diverse sample of immigrants, is a useful survey instrument to evaluate the health and well-being of special populations.     

THE CONTINUING INTERACTION OF SCIENCE AND RELIGION

Abstract. Stephen I Gould's notion of non‐overlapping magisteria (NOMA) is neither experientially supported nor rationally justifiable. Influence flows between science and religion, as when evolutionary thinking encouraged theology to adopt a kenotic view of the Creator's act of allowing creatures to be and to make themselves. Alleged simplistic dichotomies between science and religion, such as motivated belief contrasted with fideistic assertion, are seen to be false. Promising topics in the currently vigorous dialogue between science and religion include relational ontology, eschatological credibility, and ethical issues relating to advances in human genetics.     

Interval-timing deficits in individuals at high risk for schizophrenia

A duration-bisection procedure was used to study the effects of signal modality and divided attention on duration classification in participants at high genetic risk for schizophrenia (HrSz), major affective disorder (HrAff), and normal controls (NC). Participants learned short and long target durations during training and classified probe durations during test. All groups classified visual signals as shorter than equivalent duration auditory signals. However, the difference between auditory and visual signal classification was significantly larger for the HrSz group than for the NC group. We posit a model in which there is a clock rate difference between auditory and visual signals due to an attentional effect at the level of a mode switch that gates pulses into an accumulator. This attentionally mediated clock rate difference was larger for the HrSz participants than for the NC participants, resulting in a larger auditory/visual difference for the HrSz group.     

Atypical lateralization of memory for location: effects of deafness and sign language use

This paper examines the impact of auditory deprivation and sign language use on the enhancement of location memory and hemispheric specialization using two matching tasks. Forty-one deaf signers and non-signers and 51 hearing signers and non-signers were tested on location memory for shapes and objects (Study 1) and on categorical versus coordinate spatial relations (Study 2). Results of the two experiments converge to suggest that deafness alone supports the atypical left hemispheric preference in judging the location of a circle or a picture on a blank background and that deafness and sign language experience determine the superior ability of memory for location. The importance of including a sample of deaf non-signers was identified.     

Neural mechanisms of affective interference in schizotypy

Negatively valenced stimuli foster cognitive impairment in schizotypy and schizophrenia. To identify relevant brain mechanisms, the authors had 16 positive-schizotypy and 16 control participants perform an emotional Stroop task, judging the ink color of negative and neutral words during functional magnetic resonance imaging (fMRI) of regional brain activity. Schizotypy individuals showed increased right and decreased left activity in dorsolateral prefrontal cortex, indicating a deficit in maintenance of attentional set in the presence of negative emotional distractors. They also showed abnormal activity in ventral limbic areas, including decreased activity in nucleus accumbens and increased activity in hippocampus and amygdala, a circuit involved in the integration of cognitive and affective processes. These results indicate that aspects of emotion-cognition processes and the brain mechanisms that implement them are similar in schizotypy and schizophrenia.     

Toward a biopsychosocial model for 21st-century genetics

Advances in genomic research are increasingly identifying genetic components in major health and mental health disorders. This article presents a Family System Genetic Illness model to address the psychosocial challenges of genomic conditions for patients and their families, and to help organize this complex biopsychosocial landscape for clinical practice and research. This model clusters genomic disorders based on key characteristics that define types of disorders with similar patterns of psychosocial demands over time. Key disease variables include the likelihood of developing a disorder based on specific genetic mutations, overall clinical severity, timing of clinical onset in the life cycle, and whether effective treatment interventions exist to alter disease onset and/or progression. For disorders in which carrier, predictive, or presymptomatic testing is available, core nonsymptomatic time phases with salient developmental challenges are described pre- and post-testing, including a long-term adaptation phase. The FSGI model builds on Rolland's Family System Illness model, which identifies psychosocial types and phases of chronic disorders after clinical onset. The FSGI model is designed to be flexible and responsive to future discoveries in genomic research. Its utility is discussed for research, preventive screening, family assessment, treatment planning, and service delivery in a wide range of healthcare settings.     

Studies of Work: Achieving Hybrid Disciplines in IT Design and Management Studies

We explore the relationship between ethnomethodology (EM), ethnography and the needs of managers and designers in industry, considering both ethnomethodological and industrial criteria of adequacy and explicating their relationship through the concept of “audience.” We examine a range of studies in this light, with a view to their possible candidacy as hybrid studies and identify three types of application of EM studies of work: market research, design, and business improvement. Application in the first of these fields we dub “anthropological,” in that it consists in studying and reporting back on the ways of exotic people (customers). This is the application most commonly found in studies of computer supported co-operative work (CSCW). A second CSCW application, “technomethodology,” involves the introduction of EM concepts into the design process. A further application, dubbed “holding-up-a-mirror,” involves reporting back to members of a setting upon their own activities. We argue that technomethodology and holding-up-a-mirror both offer the possibility of creating hybrid disciplines. We consider the objection that improvement and design involve the introduction of value judgements that threaten the practice of EM indifference, arguing that action research can serve as a guarantee of unique adequacy (UA) by testing the researcher’s understanding as analysis in action in the setting. Furthermore, the standard of reporting required by the UA criterion contributes to the effectiveness of proposed solutions.     

Depression and Contributors to Vocational Satisfaction in Roman Catholic Secular Clergy

A nationally selected, random sample of Roman Catholic secular (i.e., diocesan) priests was examined using the Center for Epidemiological Studies-Depression scale and an instrument developed for this study to assess contributors to priests' vocational satisfaction. In addition, a self-report inventory gathered information regarding participants' demographics as well as four categories of predictor variables (i.e., overall level of vocational satisfaction, social support, spiritual activities, physical environment). The study yielded a response rate of 45%. Secular clergy reported rates of depression approximately seven times greater than are found in the general population, and also indicated that the recent sexual abuse scandal in the Roman Catholic church had negatively affected their mood. Priests' engagement in sacramental activities contributed greatly to their vocational satisfaction, and low levels of vocational satisfaction were found to be most predictive of depression. Factors comprising priests' vocational satisfaction were External Manifestations (e.g., preaching, teaching), Internal Manifestations (e.g., prayer life, affirmation of God's call), and Social Manifestations (e.g., relationships with parishioners, appreciation from others).
