How Many is Enough? Determining Optimal Sample Sizes for Normative Studies in Pediatric Neuropsychology

The purpose of this investigation was to determine how confidence intervals (CIs) for pediatric neuropsychological norms vary as a function of sample size, and to determine optimal sample sizes for normative studies. First, the authors calculated 95% CIs for a set of published pediatric norms for four commonly used neuropsychological instruments. Second, 95% CIs were calculated for varying sample size (from n?=?5 to n?=?500). Results suggest that some pediatric norms have unacceptably wide CIs, and normative studies ought optimally to use 50 to 75 participants per cell. Smaller sample sizes may lead to overpathologizing results, while the cost of obtaining larger samples may not be justifiable.     

How is Moral Disagreement a Problem for Realism?

Moral disagreement is widely held to pose a threat for metaethical realism and objectivity. In this paper I attempt to understand how it is that moral disagreement is supposed to present a problem for metaethical realism. I do this by going through several distinct (though often related) arguments from disagreement, carefully distinguishing between them, and critically evaluating their merits. My conclusions are rather skeptical: Some of the arguments I discuss fail rather clearly. Others supply with a challenge to realism, but not one we have any reason to believe realism cannot address successfully. Others beg the question against the moral realist, and yet others raise serious objections to realism, but ones that—when carefully stated—can be seen not to be essentially related to moral disagreement. Arguments based on moral disagreement itself have almost no weight, I conclude, against moral realism.

Sphincter of Oddi dysfunction: Does Psychosocial Distress Play a Role?

Sphincter of Oddi dysfunction (SOD) is a functional gastrointestinal disorder characterized by pancreatobiliary-type of pain in the absence of organic abnormalities. The aim of this study was to investigate specific psychosocial predictors of functional outcome in a group of patients consecutively referred to a gastroenterological department for biliary-type of pain. Based on medical examination patients were divided into functional (SOD) and organic groups. Self-administered questionnaires regarding demographic characteristics, psychological distress (Symptom Check-List-90–R, [SCL-90-R]), severity of acute and chronic stress, level of subjective well-being and satisfaction with health were completed. The analyses were based on the logistic regression approach. In this sample, SOD patients were older than organic patients and more likely female. Logistic regression analysis showed that higher acute stress (i.e., main effect) was associated with a decreased likelihood of functional (SOD) outcome, whereas the combination of acute stress with chronic stress and the combination of acute stress with higher severity of psychopathology (i.e., interaction effect) was associated with an increased likelihood of functional (SOD) outcome. These findings suggest stressful life events in combination with certain psychological symptoms can play a role in the symptom presentation of patients with sphincter of Oddi dysfunction.     

Problem Drinking: A Problem for the Theory of Reasoned Action?1

The present study examined the sufficiency of the theory of reasoned action (TRA) to predict intention and behavior with respect to problem drinking, as well as the ability of the theory of planned behavior (TPB) to predict intention and behavior over and above the TRA. The role of perceived control in the TPB was also examined. A 12-year longitudinal study on alcohol and drug use attitudes and behavior provided the context for this investigation. Two criterion variables were examined: intention to get drunk and frequency of getting drunk. It was hypothesized that heavier drinkers would perceive less control over their drinking. Coincidentally, the TRA, which assumes the behavior being predicted is volitional, would become less predictive as drinking became heavier. Furthermore, the TPB, which extends the TRA to include perceived (volitional) control over the behavior would be more predictive of intention and behavior than the TRA. All three hypotheses were supported. In addition, perceived control proved to be differentially predictive for nonproblem and problem drinkers. Specifically, perceived control contributed to the prediction of intention to get drunk for nonproblem drinkers, but to the prediction of behavior (frequency of getting drunk) for problem drinkers. Implications of these results for theory development and application are discussed.     

The Problem of a Subjective Authenticity and the Articulation of Belonging among the Irish in England—A Psychosocial Approach

This article presents the question of identity and authenticity as a problematic one, capable of investigation through a psychosocial lens. “Authenticity,” as explored by Erickson (1995) and Weigert (2009), may be understood as a commitment to self-values, meaning and motivation. Feeling “true to oneself” thus becomes an intensely personal affective project, which remains theoretically the preserve of the individual subject, and thus incapable of challenge by others. However, as identity is inherently social, there is a need to interrogate the affective nature of belonging to a collective identity. In particular, I consider how this personalised sense of authenticity may come into conflict with the need to have one’s personal identity recognised as authentic within the wider set of meaning-makings around the collectivity. I argue that this problem of authenticity and belonging may arise in the interplay between the personal and the collective in three ways: reflection, recognition and ownership. Any articulation of belonging to a collective identity whilst maintaining a personally “felt” authenticity must negotiate these three aspects. In this article, I develop these ideas through my own recent research on discourses of authenticity among the Irish in England. Drawing on Wetherell’s (2012) recent articulation of the affective-discursive, I explore how one second-generation Irish woman articulates her experiences of “belonging” and personal “authenticity” in interview talk. I argue that the resolution of dilemmas around the affective and collective nature of authenticity can be usefully investigated by attending to the co-construction of the interview between participant and interviewer. The positioning of the interviewer and the power dynamics of the interview thus become key modes of enquiry in the psychosocial analysis of authenticity.     

Happiness in a Flux? The Instability Problem

In the recent discussion of happiness it has become popular to claim that being happy means having a certain positive attitude towards your life. This attitude involves both a judgement that your life measures up to your standards and a feeling of satisfaction with your life. In this paper, I am going to discuss a serious problem inherent in this account that has important ramifications for the normative question of how we ought to pursue happiness. If happiness is in part determined by your standards, how shall we determine whether you are happier in one life than in another when your standards change across these lives? Perhaps you will judge a life as a parent as better than a childless life, if you were to become a parent, but judge a childless life as better than a parenting life, if you were to remain childless. Which standard should determine the comparative happiness of the two lives? In this paper, I shall argue that some innocent-looking answers to this question will generate inconsistencies. To find an acceptable resolution, we need to make a difficult choice between what on the face of it look like two equally valid principles of happiness.     

Is There a Crisis in Clergy Health?: Reorienting Research Using a National Sample

Are religious leaders unusually unhealthy? This question has long occupied scholars interested in the study of religious institutions, and a significant body of research has examined the causes, correlates, and effects of poor health among clergy. In this study, we aimed to: (1) outline the development of, and bias inherent to, the scholarly understanding of clergy health over the past 50 years; (2) test, using a recently collected nationally representative sample of clergy, the standing assumption that clergy are an especially unhealthy vocational group, specifically in terms of depression, obesity, and self-rated health; and (3) identify the major correlates of health among clergy using these data. Contrary to the recent tenor of scholarly research on this subject, our research revealed that clergy are not a particularly unhealthy group. We suggest potential pathways forward to ameliorate the bias inherent in the research into clergy well-being.     

Is Attachment to God a Unique Predictor of Mental Health? Test in a Jewish Sample

Research suggests that religion and spirituality generally correlate positively with various aspects of mental health, although mediators remain unclear. We explored whether attachment to God is a unique predictor above and beyond other key religious variables within a Jewish sample. Given the religion-as-culture perspective suggesting that Judaism can be characterized as primarily focused on behavior versus internal mental experiences, we expected that attachment to God would be less relevant to Jewish mental health. Surprisingly, attachment emerged as the strongest predictor of mental health among both more traditional Orthodox Jewish participants and less traditional non-Orthodox Jews. Although additional cross-cultural research is clearly needed, our results suggest that even in more behaviorally focused religious cultures, attachment to God is a key mediator of the protective effects of religion and spirituality.     

Is There a Problem of Special Angelic Action?

One of the most widely discussed topics in the recent science & theology literature has been divine activity. It is odd that in this literature there has been no discussion of whether and how to accommodate special angelic action (hereafter SAA). Just as the Bible records many instances of apparent SDA, it records many instances of apparent SAA. This neglect may be due to an assumption that there is no distinct problem relating to SAA; the existing suggested solutions to the problem(s) surrounding SDA may be transferable to the angelic context. My aim is to disprove that idea.     

Is the Problem of Divine Hiddenness a Problem for the Reformed Epistemologist?

The problem of divine hiddenness, currently a much‐discussed topic in analytic philosophy of religion, can be (roughly) summarized in the question, ‘Why is God not more obvious or apparent?’ Sometimes the problem is used to undermine theistic belief. Here we seek to add a unique contribution to the growing debate on this theme from the perspective of Reformed epistemology, particularly Alvin Plantinga's construal; moreover, we do so in a way that is theologically relevant. We conclude, with assistance from Scripture and from Plantinga, that the problem of divine hiddenness is not a problem for the Reformed epistemologist.     

How does one speak of social psychology in a nation in transition?

Abstract: Although South Africa's transition into nationhood has been remarkable by all measures, persistent inequalities remain. These are directly traceable to the impact of the social engineering of apartheid which has left a legacy of poverty and a lack of education. In this talk, I focus on three key dilemmas for South Africans: identity as a nation of citizens with multiple identities, capacity for self‐knowledge and self‐acceptance and openness to new impulses. Acceptance of multiple identities is widespread but how deep is the acceptance of difference, especially when conflicts of opinion emerge? Finding a language of self‐knowledge and acceptance requires a language that enables us to gain greater mastery of the complexities of living in a diverse society. How can psychology help with this task? In African cultures illness is described as a visitation from the ancestors: affected persons become wounded healers whose healing powers come from their acknowledged weakness. To what extent might you, as analytical psychologists, help find the ritual processes and language to be effective healers of your own nation?     

Embracing Change: Examination of a “Capabilities and Benevolence” Beliefs Model in a Sample of Military Cadets

This research used a capabilities and benevolence framework to examine 2 characteristics (learning orientation and propensity to trust) potentially associated with a cadet's attitudes and responses to organizational change. The research hypothesized that cadets with a high learning orientation and a high propensity to trust others will hold a significantly more positive attitude toward change than other individuals, even when controlling for the cadet's general dispositional resistance to change. Findings confirmed the hypothesis regarding learning orientation but not trust. Discussion focused on how organizations, by identifying the factors associated with a person's dispositional orientation, may ultimately develop better interventions to influence responses to change and increase the overall effectiveness of change initiatives.     

Sex differences in intellectual functioning: How much of a difference do genes make?

An X-linkage theory of inheritance of genes controlling sex differences in major intellectual traits is critically examined. A review of the research suggests that the mechanism of inheritance of differences in spatial visualization ability is X-linked recessive and its expression is probably testosterone-limited. However, the evidence concerning inheritance of differences in IQ does not support an X-linkage theory. Several characteristics of heritability estimates are discussed, including their specificity to a particular population at a certain point in time, their fluctuation with changes in amount of environmental variation, and the necessity of unconfounding sex and treatment in order to better determine the relationship between heritability and changeability of sex differences in specific intellectual trait expression.Parts of this paper were presented at the Western Psychological Association Convention, 1974.     

How Are Different Properties of a Scene Encoded in Visual Memory?

Recent studies in scene perception suggest that much of what observers believe they see is not retained in visual memory. Depending on the roles they play in organizing the perception of a scene, different visual properties may require different amounts of attention to be incorporated into a mental representation of the scene. The goal of this study was to compare how three visual properties of scenes, colour, object position, and object presence, are encoded in visual memory. We used a variation on the change detection “flicker” task and measured the time to detect scene changes when: (1) a cue was provided regarding the type of change; and, (2) no cue was provided. We hypothesized that cueing would enhance the processing of visual properties that require more attention to be encoded into scene representations, whereas cueing would not have an effect for properties that are readily or automatically encoded in visual memory. In Experiment 1, we found that there was a cueing advantage for colour changes, but not for position or presence changes. In Experiment 2, we found the same cueing effect regardless of whether the colour change altered the configuration of the scene or not. These results are consistent with the idea that properties that typically help determine the configuration of the scene, for example, position and presence, are better encoded in scene representations than are surface properties such as colour.     

Time Perception: Does It Distinguish ADHD and RD Children in a Clinical Sample?

This study used a double-dissociation design to evaluate whether children with ADHD demonstrated specific deficits relative to children with Reading Disorders. Recent theory suggests that ADHD children have deficits in time perception and working memory, whereas RD children have deficits in phonological decoding. The performance of 113 clinic-referred children aged 6-11 was examined using measures of working memory, phonological processing, and time perception. Respondents completed two time production tasks in which they were to judge when 30-s had elapsed, and another in which they were asked to estimate the duration of the Conners' CPT (CCPT). Time Perception and phonological processing variables were submitted to a 2 x 2 ANCOVA (ADHD vs. RD), covarying for age, SES, IQ, and working memory. Children with ADHD were more likely to overestimate the time taken for the CCPT than children without ADHD, but no group differences were found on the 30-s estimation tasks. Children with RD did not display deficits in time estimation, but showed deficits in auditory phonological processing. The lack of interaction effects supported an "etiological subtype" over the "phenocopy" model of ADHD and RD. No group differences were detected using the CCPT. Although our previous studies did not find an order effect for the Conners' CPT in a 1-hr battery, a fatigue effect was evident with a 1.5-hr battery. The implications for Barkley's behavioral inhibition theories (R. Barkley, 1997) are discussed.     

Social Problems in ADHD: Is it a Skills Acquisition or Performance Problem?

Recent models suggest that social skills training’s inefficacy for children with ADHD may be due to target misspecification, such that their social problems reflect inconsistent performance rather than knowledge/skill gaps. No study to date, however, has disentangled social skills acquisition from performance deficits in children with ADHD. Children ages 8–12 with ADHD (n?=?47) and without ADHD (n?=?23) were assessed using the well-validated social behavioral analysis framework to quantify cross-informant social skills acquisition deficits, performance deficits, and strengths. Results provided support for the construct and predictive validities of this Social Skills Improvement System (SSIS) alternate scoring method, including expected magnitude and valence relations with BASC-2 social skills and ADHD symptoms based on both parent and teacher report. Acquisition deficits were relatively rare and idiosyncratic for both the ADHD and Non-ADHD groups, whereas children with ADHD demonstrated cross-informant social performance deficits (d?= 0.82–0.99) on several specific behaviors involving attention to peer directives, emotion regulation, and social reciprocity. Relative to themselves, children with ADHD were perceived by parents and teachers as exhibiting more social strengths than social acquisition deficits; however, they demonstrated significantly fewer social strengths than the Non-ADHD group (d?=??0.71 to ?0.89). These findings are consistent with recent conceptualizations suggesting that social problems in ADHD primarily reflect inconsistent performance rather than a lack of social knowledge/skills. Implications for refining social skills interventions for ADHD are discussed.
