Temperature dependency in motor skill learning

The present study investigated the role of temperature as a contextual condition for motor skill learning. Precision grip task training occurred while forearm cutaneous temperature was either heated (40-45 °C) or cooled (10-15 °C). At test, temperature was either reinstated or changed. Performance was comparable between training conditions while at test, temperature changes decreased accuracy, especially after hot training conditions. After cold training, temperature change deficits were only evident when concurrent force feedback was presented. These findings are the first evidence of localized temperature dependency in motor skill learning in humans. Results are not entirely accounted for by a context-dependent memory explanation and appear to represent an interaction of neuromuscular and sensory processes with the temperature present during training and test.     

The importance of modeling method effects: resolving the (uni)dimensionality of the loneliness questionnaire

This study sought to resolve the dimensionality of the Loneliness Questionnaire (LQ; Asher, Hymel, & Renshaw, 1984) by applying recommended confirmatory factor analytic procedures that control for method effects (Brown, 2003). This study was needed given that inconsistent findings have been reported recently regarding the structure of this instrument (Bagner, Storch, & Roberti, 2004) and all models to date have not accounted for method effects due to the non-reversed-worded and reversed-worded items of this instrument. Using a large sample of youth in Grades 2 through 12 (N = 11,725), we compared the previously reported 1- and 2-factor models with a newly posited 1-factor model that incorporated correlated error terms to account for method effects. We found that the 1-factor model that included correlated error terms fit the data best, and that this factor structure evidenced measurement invariance across boys and girls in childhood, but not in adolescence. The meaning of the LQ indicators was also consistent for boys across development, but evidenced differences for girls in childhood versus adolescence. More generally, it was demonstrated that modeling method effects is vital to accurately understanding the dimensionality of loneliness when reversed-worded and non-reversed-worded items are used as indicators. The measurement and clinical implications of these findings are discussed.     

Lab support for strong reciprocity is weak: punishing for reputation rather than cooperation

Strong reciprocity is not the only account that can explain costly punishment in the lab; it can also be explained by reputation-based accounts. We discuss these two accounts and suggest what kinds of evidence would support the two different alternatives. We conclude that the current evidence favors a reputation-based account of costly punishment.     

Marital Name Changing Attitudes and Plans of College Students: Comparing Change Over Time and Across Regions

This study examines time period and regional effects on U.S. college students’ attitudes and plans regarding marital naming. Data were gathered at a Midwestern college in 1990 and 2006 and at an Eastern university in 2006 (N?=?867). No time period effect was identified for marital name plans in the Midwest samples. Women were neither more nor less likely to plan to retain their birth name in 1990 as compared to 2006. A time period effect was found for attitudes: Midwest women in 2006 were more likely to say a woman was more committed to the marriage if she took her husband’s last name as compared to Midwest women in 1990. This indicates that women in the Midwest may have become more conservative over time. We also found regional differences: women in the East were significantly more likely than women in the Midwest to plan to keep their birth surname upon marriage. Findings suggest a trend toward more conservative attitudes over time and location although plans, perhaps due to the rareness of maintaining a birth surname upon marriage, have not changed.     

Test of a cultural framework of parenting with Latino families of young children

This study examined the mental health and academic functioning of 442 4- and 5-year old children of Mexican (MA) and Dominican (DA) immigrant mothers using a cultural framework of Latino parenting. Data were collected on mothers' self-reported acculturative status, parenting practices and cultural socialization, and on children's behavioral functioning (mother- and teacher-report) and school readiness (child test). Results provide partial support for the validity of the framework in which mothers' acculturative status and socialization of respeto (a Latino cultural value of respect) and independence (a U.S. American cultural value) predict parenting practices. For both groups, English language competence was related to less socialization of respeto, and other domains of acculturative status (i.e., U.S. American/ethnic identity, and U.S. American/ethnic cultural competence) were related to more socialization of respeto and independence. Socialization of respeto was related to the use of authoritarian practices and socialization of independence was related to the use of authoritative practices. Socialization of respeto was also related to lower school readiness for DA children, whereas socialization of independence was related to higher school readiness for MA children. Independence was also related to higher teacher-rated externalizing problems for MA children. For both groups, authoritarian parenting was associated with more parent-reported internalizing and externalizing problems. The discussion focuses on ethnic subgroup differences and similarities to further understanding of Latino parenting from a cultural perspective.     

Bagpipe music

Ancient philosophy is in a bad way. Like all other academic disciplines, it is crushed by the embrace of bureaucracy. Like other parts of philosophy, it is infected by faddishness. And in addition it suffers cruelly from the decline in classical philology. There is no cure for this disease.     

PUTTING PRESUPPOSITIONS ON THE TABLE: WHY THE FOUNDATIONS MATTER

Abstract. Over time scientists have developed an effective investigative process that includes the acceptance of particular basic presuppositions, methods, content, and theories. The deeply held presuppositions are the philosophical foundation of scientific thought and do much to define the field's worldview. These fundamental assumptions can be esoteric for many and can become a source of conflict when they are not commonly shared with other points of view. Such presuppositions affect the observations, the conclusions drawn, and the positions taken. Furthermore, in some cases presuppositions in science have undergone important shifts in meaning, causing an increasing dissonance. We argue that disputes in religion and science often are due to these very basic differences in philosophy that are held by members in the different communities. To better understand the nature of science and its differences with religious views, presuppositions rather than conclusions should be articulated and examined for validity and scope of application.     

Brief counseling to reduce AIDS risk in intravenous drug users and their sexual partners: Preliminary results

Intravenous drug users (N = 88) and their sexual partners (N = 45) were randomly assigned to either a brief counseling intervention or an information-brochure only condition (aimed at reducing behavioral risk for HIV infection). At 10 day follow-up, intravenous drug users exposed to brief counseling were more knowledgeable about risk behaviors, and reported higher levels of self-efficacy and communication skill, and more frequent use of condoms and sterilisation of needles. At 90 day follow-up, intravenous drug users were more accepting of guidelines to reduce sex-related risk and reported greater self-efficacy in relation to drugs. Sexual partners who received brief counseling showed a small reduction in unprotected sex (at 90-day follow-up), while those receiving brochures were slightly less likely to use condoms. Methodological problems of the study are discussed.     

A short-term group therapy model for treatment of adult female survivors of childhood incest

Childhood incest has been experienced by a minimum of one million American women. Because of the dynamic of secrecy in these families and society's discomfort with the issue, disclosure frequently does not take place until adulthood. A treatment modality for adult women following disclosure of a childhood incest experience has been devised. A short-term semi-structured group model has been chosen which creates an atmosphere of rapid cohesion and helps participants broaden their identity beyond that of victim. This paper reports participants' demographic and historical data as well as thematic content and group evaluative data from the first nine such groups conducted in a major health maintenance organization in the Boston area. Findings suggest that childhood incest has widespread and long-lasting effects on women's functioning, including ability to trust and form relationships, emotional functioning and self-esteem, and the ability to protect self and children from victimization. The group was felt to be extremely valuable by the majority of participants and was experienced by many as the first place they ever found safety, unconditional nurturance, and a sense of belonging. Other findings include the repetition of incest over generations, the nonresponsiveness of adults in cases where disclosure had taken place in childhood, and the importance of an empathic yet well-bounded therapist.
