Association of the Thin Body Ideal, Ambivalent Sexism, and Self-Esteem with Body Acceptance and the Preferred Body Size of College Women in Poland and the United States

A study of body satisfaction in 111 Polish and 83 U.S. college women indicated that when Body Mass Index (BMI) was controlled Polish women had larger perceived body sizes and desired a larger body ideal. The Polish sample had higher scores on the Hostile and Benevolent Sexism scales (Glick & Fiske, 1996), whereas the U.S. sample scored higher on the Internalization scale of the Sociocultural Attitudes Toward Appearance Questionnaire (SATAQ; Heinberg, Thompson, & Stormer, 1995). Benevolent sexism was related to the acceptance and use of cosmetics in the Polish sample, but not in the U.S. sample. The SATAQ Awareness and Internalization scales were related to low body acceptance in both samples. The Internalization scale was related to discrepancies between the respondents' own bodies and their ideal body types in the U.S. sample but not in the Polish sample. Although the Polish and U.S. samples were more alike than different, sexism was strongly associated with body dissatisfaction in the Polish sample, whereas the SATAQ Internalization scale was strongly associated with body dissatisfaction in the U.S. sample. The results support the hypothesis of globalization of the thin body ideal, illustrate the importance of controlling for BMI in studies of body satisfaction, and demonstrate relationships between sexism, internalization of the thin body ideal, and body dissatisfaction.     

A theoretical framework for patient-reported outcome measures

Patient-reported outcome measures (PROMs) are increasingly used to assess multiple facets of healthcare, including effectiveness, side effects of treatment, symptoms, health care needs, quality of care, and the evaluation of health care options. There are thousands of these measures and yet there is very little discussion of their theoretical underpinnings. In her 2008 Presidential address to the Society for Quality of Life Research (ISOQoL), Professor Donna Lamping challenged researchers to grapple with the theoretical issues that arise from these measures. In this paper, I attempt to do so by arguing for an analogy between PROMs and Hans-Georg Gadamer’s logic of question and answer. While researchers readily admit that the constructs involved in PROMs are imperfectly understood and lack a gold standard, they often ignore the consequences of this fact. Gadamer’s work on questions and their importance to philosophical hermeneutics helps to show that the questions researchers ask about such constructs are also imperfectly understood. I argue that these questions should not be standardized, and I instead propose a theoretical framework that understands PROMs as posing genuine questions to respondents—questions that are open to reinterpretation.     

Integrating external deduction tools with ACL2

We present an interface connecting the ACL2 theorem prover with external deduction tools. The ACL2 logic contains several mechanisms for proof structuring, which are important to the construction of industrial-scale proofs. The complexity induced by these mechanisms makes the design of the interface challenging. We discuss some of the challenges, and develop a precise specification of the requirements on the external tools for a sound connection with ACL2. We also develop constructs within ACL2 to enable the developers of external tools to satisfy our specifications. The interface is available with the ACL2 theorem prover starting from Version 3.2, and we describe several applications of the interface.     

Numerical and non-numerical ordinality processing in children with and without developmental dyscalculia: Evidence from fMRI

Ordinality is – beyond numerical magnitude (i.e., quantity) – an important characteristic of the number system. There is converging empirical evidence that (intra)parietal brain regions mediate number magnitude processing. Furthermore, recent findings suggest that the human intraparietal sulcus (IPS) supports magnitude and ordinality in a domain-general way. However, the latter findings are derived from adult studies and with respect to children (i.e., developing brain systems) both the neural correlates of ordinality processing and the precise role of the IPS (domain-general vs. domain-specific) in ordinality processing are thus far unknown. The present study aims at filling this gap by employing functional magnetic resonance imaging (fMRI) to investigate numerical and non-numerical ordinality knowledge in children with and without developmental dyscalculia. In children (without DD) processing of numerical and non-numerical ordinality alike is supported by (intra)parietal cortex, thus extending the notion of a domain-general (intra)parietal cortex to developing brain systems. Moreover, activation extents in response to numerical ordinality processing differ significantly between children with and without dyscalculia in inferior parietal regions (supramarginal gyrus and IPS).     

Depressive symptoms and parenting competence: An analysis of 13 regulatory processes

Mechanisms that lead depressive symptoms to undermine parenting are poorly understood. This review examines cognitive, affective, and motivational processes thought to be responsible for the impact of depressive symptoms on parenting. We present a five-step, action-control model and review 152 studies relevant to 13 regulatory processes. Evidence suggests that depressive symptoms undermine parenting because they reduce child-oriented goals, undermine attention to child input, increase negative appraisals of children and parenting competence, activate low-positive and high-negative emotion, and increase positive evaluations of coercive parenting. Yet, this review reveals significant limitations in knowledge of these processes. Evidence that they mediate depression-parenting relations is scare; important processes remain unstudied; conceptions of regulation are undifferentiated; children’s contributions are largely unexamined; moderating variables are largely unexplored; and methods fail to capture the dynamics of processing input from children. Rigorous testing of such process models holds promise for clarifying the basis of depression-related parenting problems.     

The effects of spontaneous and voluntary facial reactions on surprise and humor

Two investigations were conducted to determine the nature of the relationship between facial reactions and surprise and humor ratings as suggested by the facial feedback hypothesis. In the correlational investigation, individual subjects showed a positive correlation between their spontaneous facial reactions and funniness ratings over 36 cartoons (within subjects). Subjects who were facially more reactive to all the cartoons, however, did not rate them as funnier than did subjects who were less facially reactive (between subjects). In the experimental investigation, spontaneous facial reactions were evoked by a discrepant weight and also were inhibited or amplified on verbal demand. Surprise and funniness ratings varied with spontaneous facial reactions but were unaffected when those reactions were voluntarily inhibited or amplified. The results were interpreted as not supporting the facial feedback hypothesis and suggested that facial reactions may only correlate with emotional experience.These investigations were supported by Ball State University Research Grants.     

Effects of Sensory Deficit on Phalanx Force Deviation During Power Grip Post Stroke

The effect of sensory deficits on power grip force from individual phalanges was examined. The authors found that stroke survivors with sensory deficits (determined by the Semmes-Weinstein monofilament test) gripped with phalanx force directed more tangential to the object surface, than those without, although both groups had similar motor deficits (Chedoke-McMaster and Fugl-Meyer), grip strength, and skin friction. Altered grip force direction elevates risk of finger slippage against the object thus grip loss/object dropping, hindering activities of daily living. Altered grip force direction was associated with altered muscle activation patterns. In summary, the motor impairment level alone may not describe hand motor control in detail. Information about sensory deficits helps elucidate patients' hand motor control with functional relevance.
