Colour constancy and Fregean representationalism

All representationalists maintain that there is a necessary connection between an experience’s phenomenal character and intentional content; but there is a disagreement amongst representationalists regarding the nature of those intentional contents that are necessarily connected to phenomenal character. Russellian representationalists maintain that the relevant contents are composed of objects and/or properties, while Fregean representationalists maintain that the relevant contents are composed of modes of presentation of objects and properties. According to Fregean representationalists such as David Chalmers and Brad Thompson, the Fregean variety of the view is preferable to the Russellian variety because the former can accommodate purported counterexamples involving spectrum inversion without illusion and colour constancy while the latter cannot. I maintain that colour constancy poses a special problem for the Fregean theory in that the features of the theory that enable it handle spectrum inversion without illusion cannot be extended to handle colour constancy. I consider the two most plausible proposals regarding how the Fregean view might be developed in order to handle colour constancy—one of which has recently been defended by Thompson (Australas J Philos 87:99–117, 2009)—and argue that neither is adequate. I conclude that Fregean representationalism is no more able to accommodate colour constancy than is Russellian representationalism and, as such, ought to be rejected.     

Trajectory of Adolescent Obesity: Exploring the Impact of Prenatal to Childhood Experiences

This study examined longitudinal associations of prenatal exposures as well as childhood familial experiences with obesity status from ages 10 to 18. Hierarchical generalized linear modeling was applied to examine 5,156 adolescents from the child sample of the 1979 National Longitudinal Survey of Youth. Higher maternal weight, maternal smoking during pregnancy, lower maternal education, and lack of infant breastfeeding were contributors to elevated adolescent obesity risk in early adolescence. However, maternal age, high birth weight of child, and maternal annual income exhibited long-lasting impact on obesity risk over time throughout adolescence. Additionally, childhood familial experiences were significantly related to risk of adolescent obesity. Appropriate use of family rules in the home and parental engagement in children’s daily activities lowered adolescent obesity risk, but excessive television viewing heightened adolescent obesity risk. Implementation of consistent family rules and parental engagement may benefit adolescents at risk for obesity.     

Assessing the Clinical Competence of Psychology Students Through Objective Structured Clinical Examinations (OSCEs): Student and Staff Views

Objective Structured Clinical Examinations (OSCEs) are a well‐known, reliable, and valid assessment method used across the healthcare sector. In the present study, we applied OSCEs in three units within professional postgraduate psychology courses, with the broad aims of identifying staff and student perceptions of the assessment. At the conclusion of each OSCE, staff and students completed a feedback questionnaire that contained both scaled and open‐ended questions. Results suggest that clinical psychology OSCEs can be stressful for students, but are also well regarded. Both staff and students felt that the OSCEs were realistic, valid, and aligned well with professional practice. Students reported differences in the way in which they prepared for the OSCEs compared with a written exam or other form of assessment, while staff noted that models of OSCE development must be flexible, to adequately assess the objectives of individual units. Further, because they can be a costly exercise, OSCEs need to be applied judiciously within the tertiary sector.     

Dad2K: An Adaptation of SafeCare to Enhance Positive Parenting Skills With At-Risk Fathers

Positive father involvement in the lives of their children is critically important. This article describes pilot data from the Dad2K program, an adaptation of the evidence-based SafeCare Parent-Child Interaction module, which targets positive parenting skills and the prevention of child neglect and physical abuse. Dad2K includes a unique approach to intervention delivery utilizing computer software, and instruction and practice with a home visitor provider. The development process of the Dad2K program is described, and data are presented from four fathers of young children who completed the program. The article concludes with describing the next steps in the examination of the Dad2K program, which includes a large randomized control trial funded by the National Institute of Minority Health and Health Disparities.     

The Effect of War Stressors and Life Events on Gulf War Veterans With Chronic Fatigue Syndrome Symptoms

This study examines the association of life stressors and the period when they occur, with the development of chronic fatigue syndrome (CFS) symptoms in Gulf War veterans. Of data collected from Gulf War Health Registry veterans, 113 met CFS criteria and 441were controls. After hierarchical multiple regression, several negative life stressors were associated with CFS group membership: being wounded, experiencing a traumatic war experience, frequent battle experiences, demotion, and unable to work within 2 years of returning from the Gulf. The positive life stressor of buying a house more than 2 years after returning protected against being in the CFS group. The findings are consistent with etiological hypotheses of CFS incorporating a psychosocial component and are useful in developing programs for veterans returning from war.
