Perception of Affordances for Walking Under a Barrier From Proximal and Distal Points of Observation

We investigated perception of affordances for a given behavior from points of observation other than that from which the behavior is to be performed. Participants viewed a horizontal barrier from different points of observation and reported whether they would be able to walk under that barrier. In Experiment 1, they viewed the barrier both while standing on the floor and while sitting on the floor. In Experiment 2, they viewed the barrier both while standing on the floor and while standing on a step stool. The results show that although perception of this affordance is body-scaled regardless of point of observation, there are subtle differences in the perceptual boundaries in each case. Such differences are likely due to differential attunement to the information specifying the affordance at each point of observation.     

Stress and Well-Being Among Parents of Children with Potocki-Lupski Syndrome

Potocki-Lupski syndrome (PTLS) or duplication 17p11.2 syndrome is a newly characterized condition causing a variety of health problems with variable severity, including failure to thrive in infancy and childhood, hypotonia, structural heart anomalies, cognitive impairments, speech and learning difficulties, and autism. Due to its recent clinical characterization little is known about the psychosocial impact of this condition on patients and their families. This study evaluated whether parental psychosocial outcomes were associated with children’s PTLS disease severity. Parents of 58 children with PTLS completed a cross-sectional survey that assessed parental stress, quality of life, and coping skills. Parental functioning was associated with greater severity of feeding difficulty and with lower severity of a cardiovascular defect. Findings from this study highlight potential support needs of parents of children affected by PTLS and suggest ways in which these needs may be addressed.     

The Beck Depression Inventory: Item Order and the Impact of Response Sets

The lack of subtle content in the item groups of the Beck Depression Inventory (BDI) and the consistency in the ordering of the items from least to most pathological make this instrument unduly susceptible to either defensive or malingering response sets. Two experimental forms were developed for the BDI: a backwards version (a simple reversal of the order of items within each group) and a random-order version. These forms, together with the original item order, were given to college undergraduate women along with the Depression scale from the MMPI and the Burks-Martin Questionnaire covering recent life changes and current stressful situations. The random order BDI results in a significantly higher depression score than did either the original or backwards version. Correlations with the other instruments were comparable for all three forms. The random order of items within each set appears to break up a response set to endorse either the first or last item and is, therefore, recommended.     

Brief Book,Software, and Test Announcements

After reviewing literature detailing the ubiquity of error in research and assessment data, I describe mistakes found with MMPI-2 and Rorschach scores in an earlier publication (Meyer, 1993). The mistakes emerged from several sources, including hand-scoring the assessment measures, manually retrieving scores from patient files, and manually entering information for statistical analyses. The proportion of erroneous scores in the original study (MMPI-2 = 5.88%, Rorschach = 1.56%) was relatively small and reliability coefficients between the original and corrected scales were uniformly high (i.e., > .940). Consequently, the findings detailed in the original publication were not greatly affected by the mistakes that were made. Nonetheless, because this will not always be the case, I discuss the discrepancies as a way to sensitize researchers, clinicians, and students to the presence of error and then suggest several strategies for minimizing its impact on assessment data and research.     

A Comparison of the Psychological Entitlement Scale and the Narcissistic Personality Inventory's Entitlement Scale: Relations With General Personality Traits and Personality Disorders

Two studies on the relations between various styles of defense and the power or validity of self-reports on objective personality questionnaires. The power of individual items on the Rotter Internal-External Locus of Control scale to discriminate between subjects defined as internals or externals by a median-cut procedure using the total score was not affected by the presence Or absence of a projective defensive style. However, the presence of repressive tendencies did appear to restrict item power. Prediction from two achievement scales taken from Gough's California Psychological Inventory was not influenced by level of repression, was affected somewhat adversely by a projective style, and was most clearly contaminated by a rationalizing defense. It was proposed that the differential effects of defensive styles upon the validity of personality tests depended upon the convergence or divergence of the cognitive operations involved in the type of defense and in the type of personality measure.     

An effectiveness trial of a new enhanced dissonance eating disorder prevention program among female college students

Objective

Efficacy trials indicate that a dissonance-based prevention program in which female high school and college students with body image concerns critique the thin-ideal reduced risk factors, eating disorder symptoms, and future eating disorder onset, but weaker effects emerged from an effectiveness trial wherein high school clinicians recruited students and delivered the program under real-world conditions. The present effectiveness trial tested whether a new enhanced dissonance version of this program produced larger effects when college clinicians recruited students and delivered the intervention using improved procedures to select, train, and supervise clinicians.

Method

Young women recruited from seven universities across the US (N = 408, M age = 21.6, SD = 5.64) were randomized to the dissonance intervention or an educational brochure control condition.

Results

Dissonance participants showed significantly greater decreases in risk factors (thin-ideal internalization, body dissatisfaction, dieting, negative affect) and eating disorder symptoms versus controls at posttest and 1-year follow-up, resulting in medium average effect size (d = .60). Dissonance participants also reported significant improvements in psychosocial functioning, but not reduced health care utilization or unhealthy weight gain.

Conclusions

This novel multisite effectiveness trial with college clinicians found that the enhanced dissonance version of this program and the improved facilitator selection/training procedures produced average effects that were 83% larger than effects observed in the high school effectiveness trial.     

Temperament in early childhood and peer interactions in third grade: The role of teacher–child relationships in early elementary grades

Children's interactions with peers in early childhood have been consistently linked to their academic and social outcomes. Although both child and classroom characteristics have been implicated as contributors to children's success, there has been scant research linking child temperament, teacher–child relationship quality, and peer interactions in the same study. The purpose of this study is to examine children's early temperament, rated at preschool age, as a predictor of interactions with peers (i.e., aggression, relational aggression, victimization, and prosociality) in third grade while considering teacher–child relationship quality in kindergarten through second grades as a moderator and mediator of this association. The sample (N = 1364) was drawn from the NICHD Study of Early Child Care and Youth Development. Results from structural equation models indicated that teacher–child conflict in early elementary grades mediated links between children's temperament and later peer interactions. Findings underscore the importance of considering children's temperament traits and teacher–child relationship quality when examining the mechanisms of the development of peer interactions.     

Thinking animals, disagreement, and skepticism

According to Eric Olson, the Thinking Animal Argument (TAA) is the best reason to accept animalism, the view that we are identical to animals. A novel criticism has been advanced against TAA, suggesting that it implicitly employs a dubious epistemological principle. I will argue that other epistemological principles can do the trick of saving the TAA, principles that appeal to recent issues regarding disagreement with peers and experts. I conclude with some remarks about the consequence of accepting these modified principles, drawing out some general morals in defending animalism.     

In defense of nativism

This paper takes a fresh look at the nativism–empiricism debate, presenting and defending a nativist perspective on the mind. Empiricism is often taken to be the default view both in philosophy and in cognitive science. This paper argues, on the contrary, that there should be no presumption in favor of empiricism (or nativism), but that the existing evidence suggests that nativism is the most promising framework for the scientific study of the mind. Our case on behalf of nativism has four parts. (1) We characterize nativism’s core commitments relative to the contemporary debate between empiricists and nativists, (2) we present the positive case for nativism in terms of two central nativist arguments (the poverty of the stimulus argument and the argument from animals), (3) we respond to a number of influential objections to nativist theories, and (4) we explain the nativist approach to the conceptual system.     

Moral normativity

It is a platitude that morality is normative, but a substantive and interesting question whether morality is normative in a robust and important way; and although it is often assumed that morality is indeed robustly normative, that view is by no means uncontroversial, and a compelling argument for it is conspicuously lacking. In this paper, I provide such an argument. I argue, based on plausible claims about the relationship between moral wrongs and moral criticizability, and the relationship between criticizability and normative reasons, that moral facts necessarily confer normative reasons upon moral agents.
