Correcting Too Much or Too Little? The Performance of Three Chi-Square Corrections

This simulation study investigates the performance of three test statistics, T₁, T₂, and T₃, used to evaluate structural equation model fit under non normal data conditions. T₁ is the well-known mean-adjusted statistic of Satorra and Bentler. T₂ is the mean-and-variance adjusted statistic of Sattertwaithe type where the degrees of freedom is manipulated. T₃ is a recently proposed version of T₂ that does not manipulate degrees of freedom. Discrepancies between these statistics and their nominal chi-square distribution in terms of errors of Type I and Type II are investigated. All statistics are shown to be sensitive to increasing kurtosis in the data, with Type I error rates often far off the nominal level. Under excess kurtosis true models are generally over-rejected by T₁ and under-rejected by T₂ and T₃, which have similar performance in all conditions. Under misspecification there is a loss of power with increasing kurtosis, especially for T₂ and T₃. The coefficient of variation of the nonzero eigenvalues of a certain matrix is shown to be a reliable indicator for the adequacy of these statistics.     

Cortical Acetylcholine, Reality Distortion, Schizophrenia, and Lewy Body Dementia: Too Much or Too Little Cortical Acetylcholine?

Aberrations in cortical cholinergic transmission have been hypothesized to mediate the development and manifestation of psychotic cognition. Based primarily on hypotheses about mesolimbic dopaminergic hyperactivity in schizophrenia, the actions of antipsychotic drugs, the trans-synaptic regulation of the excitability of basal forebrain corticopetal cholinergic neurons, and the role of cortical cholinergic inputs in attentional functions, we hypothesized that persistent disinhibition of cortical cholinergic inputs mediates the fundamental cognitive dysfunctions which form the basis for the development of positive symptoms in schizophrenia. In contrast to this hypothesis, Perry and Perry (1995), based on evidence from hallucinating patients with Lewy Body Dementia (LBD), concluded that the extensivelossof cortical acetylcholine allows irrelevant information to enter “conscious awareness” and thus hallucinations to emerge. The discussion of these contrasting hypotheses highlights the need for more dynamic and precise theories describing the cognitive variables and neuronal processes which contribute to the development and manifestation of psychotic cognition. While the hypothesis that a disinhibited cholinergic system mediates the evolution of psychotic symptoms corresponds more convincingly with current theories about the cognitive functions of cortical cholinergic inputs, both hypotheses stress the critical role of cortical acetylcholine in the highest levels of cognitive functioning.     

What Is Too Much or Too Little? The Curvilinear Effects of Job Tension on Turnover Intent,Value Attainment,and Job Satisfaction

This study addressed 2 relatively unexplored issues in the current job stress literature. First, a significant body of research has substantiated a curvilinear relationship between job tension and performance without examining the potential impact of work stress on other important outcomes. Second, past research has failed to control for the influence of role stressors and other important variables that might alter the job-tension/work-outcomes relationship. We hypothesized that experienced job tension would predict turnover intent, value attainment, and job satisfaction, and that this relationship would be nonlinear. Data gathered from 270 hotel managers confirmed our hypotheses. Notably, tension predicted turnover intent (U shape), value attainment (inverted-U shape), and job satisfaction (inverted-U shape) in the expected manner, while explaining additional variance beyond that contributed by demographic factors, role stressors, and linear tension terms. Implications of these findings for theory and practice, as well as avenues for future research are provided.     

Is Adolescent Adjustment Following Parental Divorce a Function of Predivorce Adjustment?

This study examined whether adolescent adjustment problems which previously have been attributed to parental divorce exist prior to the divorce. Three groups (to-be-divorced, remain intact, and already divorced) were examined across four domains of adolescent functioning reported by multiple informants. The results indicated that adolescents from the to-be-divorced group functioned similarly to those who would remain in intact families but better than those in the already divorced group, suggesting that differences can be attributed to parental divorce and its accompanying disruption of family processes. Two of these processes, interparental conflict and parenting, were examined and failed to receive support.     

How Much Is Enough? The Caseload Problem

Six critical variables of the caseload problem are proposed and defined. A matrix is used to determine the ability of an employability development team to carry a greater or lesser caseload. Examples of the application of the matrix to a number of different settings are offered.     

Women and AIDS: Too Little,Too Late?

Many authors examine the governmental, the scientific, and the sexual politics of AIDS. Many of these same authors tell the AIDS story within the context of decrying homophobia. The implications of that story, however, have a troubling significance for women. This essay proposes to move the discussion of the sexual politics of AIDS beyond the confines of homophobia and to highlight issues not widely discussed outside of AIDS activist circles—issues which are having, and will continue to have, profound effects on women.     

Is Parental Knowledge of their Adolescent Offspring’s Whereabouts and Peer Associations Spuriously Associated with Offspring Delinquency?

Recent studies suggest that most of what parents know about their adolescent offspring's whereabouts and companions is the result of youth disclosure, rather than information gained through active parental monitoring. This raises the possibility that parental knowledge is spuriously correlated with youth delinquency solely because the most delinquent youth disclose the least information to parents (because they have the most to hide). We tested this spurious association hypothesis using prospective data on offspring of a nationally representative sample of US women, controlling demographic and contextual covariates. In separate analyses, greater parental knowledge of their offspring's peer associations at both 12-13 years and at 14-15 years was associated with lower odds of being in the top 1 standard deviation of youth-reported delinquency at 16-17 years, controlling for delinquency at the earlier ages. The extent to which parents set limits on activities with peers at 14-15 years did not mediate or moderate the association between parental knowledge and delinquency, but it did independently predict future delinquency among adolescents living in high-risk neighborhoods. This suggests that the association between parental knowledge and future delinquency is not solely spurious; rather parental knowledge and limit setting are both meaningful predictors of future delinquency.     

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.     

Is Global Poverty a Philosophical Problem?

Peter Singer’s groundbreaking call to action in 1972, “Famine, Affluence, and Morality,” drew philosophical attention to the topic of famine and the associated suffering or preventable death of many throughout the world. Yet despite the volume of philosophical work Singer’s paper inspired, it would still be easy to suppose that global poverty is not a problem for philosophers to take seriously in itself but is rather a particularly stark illustration or instance of a more general problem, whether in ethics or in political philosophy. The aim of this paper is to argue that the philosophical landscape of global poverty is both sui generis and sufficiently complex that the topic should be considered not as an instance of a more general philosophical problem but as a distinct area of normative inquiry.     

Is There a Problem With Cognitive Outsourcing?

To what extent can we rely on others for information without such reliance becoming epistemically problematic? In this paper, this question is addressed in terms of a specific form of reliance: cognitive outsourcing. Cognitive outsourcing involves handing over (outsourcing) one's information collection and processing (the cognitive) to others. The specific question that will be asked about such outsourcing is if there is an epistemic problem about cognitive outsourcing as such. To ask if there is an epistemic problem with x for S is to ask if x is a problem for S’s ability to acquire true belief and avoid false belief. To ask if there is a problem for S with x as such is to ask if it is impossible to solve the problem for S while leaving x as is. I argue that, if we consider the five most plausible candidate epistemic problems raised by cognitive outsourcing—i.e., unreliability, gullibility, irrationality, dependency, and lack of epistemic autonomy—we see for each candidate that it is either not an epistemic problem, or not a problem about cognitive outsourcing as such.     

Is Forgotten Evidence a Problem for Evidentialism?

The “problem of forgotten evidence” is a common objection to evidentialist theories of epistemic justification. This objection is motivated by cases where someone forms a belief on the basis of supporting evidence and then later forgets this evidence while retaining the belief. Critics of evidentialist theories argue that in some of these cases the person's belief remains justified. So, these critics claim that one can have a justified belief that is not supported by any evidence the subject possesses. I argue that these critics are mistaken.     

A note: Is it a catch or a fumble?

Following Whiting' (1986) comments on Fischman and Schneider (1985) and Smyth and Marriott (1982), this note addresses the questions of expertise in catching, the effects of sight of the hand on timing and positioning, and the difficulties of comparing performance in different experiments on catching.     

Too Much of a Good Thing? Emotional Intelligence and Interpersonal Conflict Behaviors

Research suggests that the outcomes of interpersonal conflict are determined not only by the conflict itself, but also by the way in which it is handled. Confrontational and domineering tactics have been found to magnify the adverse impact of conflict. Thus, investigations of determinants of aggressive conflict management behaviors are of considerable interest. This study extends the literature by examining the relationship between conflict management preferences and conflict management behaviors and by examining how emotional intelligence (EI) shapes this preference-behavior relationship. Individuals’ conflict management preferences predicted actual conflict management behaviors. EI was found to moderate this relationship. However, some of these moderating effects run contrary to the popular view of EI as a prosocial concept. Specifically, some EI facets were found to strengthen the link between aggressive conflict management preferences and subsequent conflict management behaviors.     

Counselor Burnout: Existential Crisis or a Problem for the Profession?

In our original article on counselor burnout (P&G, December 1976), John Shelton and I suggested that counselor-education programs created expectations for counseling that could not be realized within agency settings and contributed to counselor frustrations and disillusionment. We pointed out that one reason this problem was not widely discussed was because of the concern of counselors that their colleagues would attribute their open expression of disillusionment to their personal weaknesses. In a reply to the article, David V. Tiedeman (P&G, September 1977) took precisely this position and attributed our motivation for writing the article to our own “mid-life” crisis. This article broadens the issue to one of a fundamental difference in the ways we tend to locate the origins of problems and what this means for bringing about changes.     

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.
