Episodic Memory in Schizophrenia

Episodic memory impairments in individuals with schizophrenia have been well documented in the literature. However, despite the abundance of findings, constituent cognitive, neural, behavioral, and genetic components of the deficits continue to elude full characterization. This review provides a characterization of these deficits by organizing findings within three frameworks of interest: 1) neuroanatomical; 2) genetic; and 3) behavioral. Within each approach, evidence from imaging studies as well as behavioral studies is examined. The hope is that by synthesizing the cognitive science paradigms, molecular genetic neurophysiological findings, and computational algorithms applied to medial temporal lobe subregions, we will be able to expand our understanding of the types of compromises in episodic memory systems of individuals with schizophrenia.     

Use of the Behavioral Assessment System for Children 2nd Edition: Parent Report Scale in Pediatric Cancer Populations

This study examined the use of the Behavioral Assessment System for Children—2nd Edition: Parent Report Scale (BASC-2; Reynolds & Kamphaus, Behavior assessment system for children, 2004) in a pediatric cancer population. Comparisons of scale scores were made between pediatric cancer participants and controls. Within group comparisons were also made between subtypes of pediatric cancer. Parents of 111 children and adolescents who had experienced pediatric cancer completed the BASC-2 as part of larger studies of parent-child adjustment to cancer. Scores on the BASC-2 for cancer survivors were compared to a matched control group. Results from MANOVA analyses revealed that children with cancer were categorized as evidencing more emotional and cognitive complaints compared to the control children. Notably, no significant within group differences emerged on the subscales with regard to cancer subtype. Although preliminary, these results suggest that the BASC-2 can identify the cognitive and emotional differences between cancer survivors and controls.     

Knowing Self Through the Journey: Graduate Students’ Experiences of Self-Knowledge Development

This article explores graduate students’ experiences of a self-knowledge development course that is framed by the Heroic Journey model. Through a consideration of several theorists’ perspectives and through the voices of 13 study participants, this article examines the nature of this self-study experience and its impact on participants’ lives. In light of feminist critiques of the traditional Heroic Journey model, the author pays particular attention to the experiences of women in this course. The author identifies three major findings: First, when the Heroic journey model is understood as a process and not just a theoretical construct, it gains significant power as an inclusive tool for fostering self-knowledge development. Second, self-knowledge development is not solely an individual endeavor. Self-knowledge is socially constructed through interaction with others. Third, self-knowledge development has critical spiritual dimensions, and this deeper level of knowing can lead to significant, long-lasting growth and change.

Sexual Consent in Heterosexual Relationships: Development of a New Measure

The extensive research on date rape attitudes and experiences has left sexual consent itself largely unexamined. The objective of this study was to develop a measure to assess women’s and men’s attitudes and behaviors regarding sexual consent. Using both focus groups (N = 18) and a mail survey (N = 514) of undergraduate students at a Canadian university, two scales of sexual consent were developed: (1) a Sexual Consent Attitudes Scale, and (2) a Sexual Consent Behaviors Scale. Preliminary psychometric evidence suggested good reliability and validity. As hypothesized, women, more than men, preferred a more cautious approach to sexual consent by stressing the need to obtain consent more explicitly. Multiple regression analyses supported a reciprocal relationship between sexual consent attitudes and sexual consent behaviors.     

The structure of social relationships among captive female giraffe (Giraffa camelopardalis)

Giraffe herds have been characterized as random associations of individuals, but recent evidence suggests giraffe have a more complex social structure. The authors formulated 3 hypotheses designed to evaluate whether a herd of captive giraffe (Giraffa camelopardalis) associated randomly or patterned their behavior and proximity in a manner indicative of social relationships. Affiliative interaction, proximity, and nearest neighbors for 6 captive female giraffe living in a large outdoor enclosure were analyzed, and all three measures were nonrandomly distributed, indicating female giraffe had social preferences. Furthermore, preferences were consistent across measures and time, suggesting that adult female giraffe maintain relationships. Mother-daughter pairs and pairs with large age differences between members interacted and associated most often. The social structure of this captive herd is influenced by social relationships between individual adult females, and the social behavior of individual females should be examined more closely in the wild.     

Attention to endpoints: a cross-linguistic constraint on spatial meaning

We investigate a possible universal constraint on spatial meaning. It has been proposed that people attend preferentially to the endpoints of spatial motion events, and that languages may therefore make finer semantic distinctions at event endpoints than at event beginnings. We test this proposal. In Experiment 1, we show that people discriminate the endpoints of spatial motion events more readily than they do event beginnings-suggesting a non-linguistic attentional bias toward endpoints. In Experiment 2, speakers of Arabic, Chinese, and English each described a set of spatial events displayed in video clips. Although the spatial systems of these languages differ, speakers of all three languages made finer semantic distinctions at event endpoints, compared to event beginnings. These findings are consistent with the proposal that event endpoints are privileged over event beginnings, in both language and perception.     

Effects of caffeine on persuasion and attitude change: The role of secondary tasks in manipulating systematic message processing

Two experiments are reported that examine the effects of caffeine consumption on attitude change by using different secondary tasks to manipulate message processing. The first experiment employed an orientating task whilst the second experiment employed a distracter task. In both experiments participants consumed an orange‐juice drink that either contained caffeine (3.5 mg/kg body weight) or did not contain caffeine (placebo) prior to reading a counter‐attitudinal communication. The results across both experiments were similar. When message processing was reduced or under high distraction, there was no attitude change irrespective of caffeine consumption. However, when message processing was enhanced or under low distraction, there was greater attitude change in the caffeine vs. placebo conditions. Furthermore, attitudes formed after caffeine consumption resisted counter‐persuasion (Experiment 1) and led to indirect attitude change (Experiment 2). The extent that participants engaged in message‐congruent thinking mediated the amount of attitude change. These results provide evidence that moderate amounts of caffeine increase systematic processing of the arguments in the message resulting in greater agreement.

Varying cautionary instructions, monetary incentives, and comorbid diagnostic training in malingered psychopathology research

In this article, we combine two analogue experiments in which we empirically examined three malingering methodological issues in individuals trained and instructed to simulate posttraumatic stress disorder (PTSD) on the Trauma Symptom Inventory (TSI; Briere, 1995). In Experiment 1, we examined TSI scale effects of the following manipulations using a 2 x 2 design with 330 college students: (a) inclusion or exclusion of cautionary instructions regarding believability of participants' simulation and (b) different financial incentive levels. In Experiment 2, we examined comorbid psychiatric diagnostic training with 180 college students who were either trained to simulate PTSD and comorbid major depressive disorder or trained to simulate only PTSD. Caution main effects were significant for all but two TSI Clinical Scales, incentive main effects and interactions were only significant for one Clinical scale each, and the comorbidity manipulation did not yield any scale differences. We discuss malingering research design implications regarding the use of cautionary instructions, financial incentive levels, and comorbid training.     

Morphological Rationalism and the Psychology of Moral Judgment

According to rationalism regarding the psychology of moral judgment, people’s moral judgments are generally the result of a process of reasoning that relies on moral principles or rules. By contrast, intuitionist models of moral judgment hold that people generally come to have moral judgments about particular cases on the basis of gut-level, emotion-driven intuition, and do so without reliance on reasoning and hence without reliance on moral principles. In recent years the intuitionist model has been forcefully defended by Jonathan Haidt. One important implication of Haidt’s model is that in giving reasons for their moral judgments people tend to confabulate – the reasons they give in attempting to explain their moral judgments are not really operative in producing those judgments. Moral reason-giving on Haidt’s view is generally a matter of post hoc confabulation. Against Haidt, we argue for a version of rationalism that we call ‘morphological rationalism.’ We label our version ‘morphological’ because according to it, the information contained in moral principles is embodied in the standing structure of a typical individual’s cognitive system, and this morphologically embodied information plays a causal role in the generation of particular moral judgments. The manner in which the principles play this role is via ‘proceduralization’ – such principles operate automatically. In contrast to Haidt’s intuitionism, then, our view does not imply that people’s moral reason-giving practices are matters of confabulation. In defense of our view, we appeal to what we call the ‘nonjarring’ character of the phenomenology of making moral judgments and of giving reasons for those judgments.

Licensure of Internationally Educated Nurses Seeking Professional Careers in the Province of Alberta in Canada

While the regulation of nursing practice through licensure ensures that nurses meet minimum standards for safe competent and ethical care, it also inhibits integration of immigrant internationally educated nurses (IENs) into the Canadian professional labour market. With projections of significant nurse workforce shortages by 2010, there is impetus to enhance the numbers of licensed professional nurses through multiple strategies. The licensure processes and accompanying tensions in the Canadian context are described. As professional nurse licensure in Canada is a provincial responsibility, the situation in the Province of Alberta is used as an example. Suggestions for policy development and research include needs for better data and for gender-based analysis to address barriers to IEN licensure. The ability to practice in one’s chosen profession can be a major factor in integration of immigrants into Canadian society and thus a powerful factor in attraction and retention of highly skilled immigrants.
