Remote Limb Ischemic Conditioning at Two Cuff Inflation Pressures Yields Learning Enhancements in Healthy Adults

The authors tested whether 2 doses of remote limb ischemic conditioning (RLIC), induced via blood pressure cuff inflation, enhanced motor and cognitive learning to an equal extent, and explored a panel of blood biomarkers of RLIC. Thirty-two young adults were randomized to 3 groups and underwent a 7-day protocol of RLIC/sham followed by motor and cognitive training, with follow-up. Both RLIC groups had greater motor learning and a trend toward greater cognitive learning compared with the sham group. RLIC at the lower inflation pressure was as effective as RLIC with the higher inflation pressure. No significant candidate blood biomarkers were found. RLIC could be a well-tolerated method to enhance learning and improve rehabilitation outcomes in people with neurological conditions.     

“I Hate These Little Turds!”: Science,Entertainment, and the Enduring Popularity of Scared Straight Programs

Americans’ opinions about crime and justice are more often shaped by media coverage than by scientific evidence. A prime example of this phenomenon is Arts and Entertainment (A&E) Network’s Beyond Scared Straight program—a show that has achieved strong ratings despite the large body of empirical evidence demonstrating the ineffectiveness of inmate–juvenile confrontation tactics. To understand the complexity of American citizens’ opinions toward this program, we conducted a qualitative analysis of the online responses to the television series Beyond Scared Straight. The themes that emerged center around beliefs about the effectiveness of Scared Straight, the level of brutality displayed, its inspirational and emotional content, and its authenticity. We discuss these results in terms of the need for scholars to more effectively communicate social science information concerning what does—and does not—“work” to the public and to correctional policymakers.     

Child Conduct Problems Across Home and School Contexts: a Person-Centered Approach

To examine patterns of conduct problems across the home and school context, we used latent class analysis to analyze primary caregivers’ and teachers’ ratings on the conduct problems subscale of the Strengths and Difficulties Questionnaire (Goodman Journal of Child Psychology and Psychiatry, 38, 581–586, 1997) in the Family Life Project (N?=?1,292), a prospective study of child development in rural and small town contexts. We found a similar four-class solution at 5 and 7 years of age. In decreasing prevalence, the following classes were identified: (1) low symptoms reported by both informants (low cross-context); (2) high parent-reported symptoms, low teacher-reported symptoms (home context); (3) low parent-reported symptoms, moderate teacher-reported symptoms (school context); and (4) high symptoms reported by both informants (high cross-context). Classes exhibited stability from age five to age seven: children were more likely to remain in the same class than to transition to a different class, and longitudinal stability was especially high for children in the low cross-context class at age 5. A number of child and family characteristics measured in early childhood (executive function, verbal ability, poverty-related risk, sensitive parenting, and parental depressive symptoms) were associated with class membership at age five and age seven, but were generally not associated with longitudinal transitions between classes.     

In the Vicinity of the Human

Abstract

Beginning with the situated character of the question concerning the human, this paper argues that the problem of the human is itself inextricably bound to the problem of situation or place. Consequently, any genuine philosophical anthropology must take the form of a philosophical topology. This line of argument is developed through the work Abraham Heschel, Martin Heidegger, Martin Buber, and also Helmut Plessner.     

Shame and guilt: A hundred years of apples and oranges

An original model of shame- and guilt-related emotions is proposed and the model's theoretical background discussed. Shame is conceptualized as an affect (i.e., basic emotion), elicited by personal devaluation and evolved by social selection. Guilt is conceptualized as a cognitively assessed condition. In response to awareness of one's own condition of guilt, one may feel a number of affects or no affect. The phrase feeling guilty is a non-specific reference to feeling as one typically feels when in the condition of guilt [Ortony, A. (1987). Is guilt an emotion? Cognition and emotion, 1, 283-298]. Thus, shame as a construct represents a single affect, while feelings of guilt represent multiple affective-cognitive hybrids, which may be associated with the condition of guilt. In terms of levels of categorization [Rosch, E. (1978). Principles of categorization. In E. Rosch & B. B. Lloyd (Eds.), Cognition and categorization (pp. 27-48). Hillsdale, NJ: Erlbaum], shame, as an affect, is a basic level category with subordinates such as embarrassment and humiliation; in contrast, the multiple feelings of guilt constitute multiple subordinate affective-cognitive hybrids—subordinate to a number of basic level affects. This model integrates a great deal of existing data, suggests a large number of hypotheses, and implies the need for a profile approach to the assessment of guilt. By conceptualizing shame as an affect, and making the distinction between guilt as a state and the multiple affective-cognitive hybrids of guilt, much of the confusion and imprecision in past theory and research may be clarified.     

Gender Symmetry and Asymmetry in Violent Relationships: Patterns of Mutuality Among Racially Diverse Women

Three patterns of mutual intimate partner violence (IPV) are proposed, based on frequency and severity: Male primary perpetrator (MPP), female primary perpetrator (FPP), and symmetrical (SYM). Patterns and effects of ethnicity were examined with 445 African American, Euro-American, and Mexican American low-income women experiencing mutual IPV. More relationships were classified as MPP (54%) than SYM (35%) or FPP (11%). Comparing women's and men's perpetration of several types of IPV (e.g., threats, severe physical) indicated MPP-pattern women experienced all IPV types more often and were more likely to sustain injury than their male partners. Fewer gender differences were found in the FPP pattern. Racial/ethnic groups were more similar than different; previously reported differences may be explained by variation in socioeconomic status. The larger part of the study was funded by grant R49/CCR610508 from the National Center for Injury Prevention and Control of the Centers for Disease Control and Prevention, awarded to the third author. This article was also made possible by grant 2001-WT-BX-0504 from the National Institute of Justice awarded to the first and third authors. These agencies are not responsible for the results. Portions of this paper were presented by the first and third authors at the International Family Violence Conference in Portsmouth, NH, July, 2003.     

Early neuropsychological correlates of later clock drawing and clock copying abilities among school aged children.

Although widely used in empirical study and bedside neuropsychological evaluation of geriatric populations, there is little literature on clock copying and drawing among children. However, existing research suggests that clock drawing tests (CDTs) may be effective and efficient tools for assessing neurocognitive development in children. This paper reports data on clock drawing on demand (CDT-D) and clock drawing to copy (CDT-C) among a non-clinical sample of elementary school aged children and identifies predictive relationships between earlier measures of executive function, visuo-construction, and visual-motor coordination and CDT performance 3 years later. Similar to findings with adult samples, analyses revealed better performance on copying than on drawing. Longitudinal analyses indicate that general intelligence significantly predicted performance on both tasks. Visual-motor coordination only predicted performance on the drawing on demand subtest of the CDT.     

Threshold estimation in two-alternative forced-choice (2AFC) tasks: The Spearman-Kärber method

The Spearman-Kärber method can be used to estimate the threshold value or difference limen in two-alternative forced-choice tasks. This method yields a simple estimator for the difference limen and its standard error, so that both can be calculated with a pocket calculator. In contrast to previous estimators, the present approach does not require any assumptions about the shape of the true underlying psychometric function. The performance of this new nonparametric estimator is compared with the standard technique of probit analysis. The Spearman-Kärber method appears to be a valuable addition to the toolbox of psychophysical methods, because it is most accurate for estimating the mean (i.e., absolute and difference thresholds) and dispersion of the psychometric function, although it is not optimal for estimating percentile-based parameters of this function.
