MULTIPLE-CHOICE AND CONSTRUCTED RESPONSE TESTS OF ABILITY: RACE-BASED SUBGROUP PERFORMANCE DIFFERENCES ON ALTERNATIVE PAPER-AND-PENCIL TEST FORMATS

We present an example of an innovative constructed response test format–a write-in/mark-in paper-and-pencil test–as an alternative to the traditional multiple-choice paper-and-pencil test, with the potential for reducing subgroup differences. We present subgroup differences data on these 2 paper-and-pencil test formats on an operational promotional exam in a sample of African American and White firefighters. The tests were designed to measure the same content domain. Using within-subjects data that compared the performance of 13 African American and 14 White fire captains, and between-subjects data that compared the performance of 21 African American and 49 White fire captains, several results were in the predicted direction such that subgroup differences were reduced on the constructed response test. However, these results did not reach statistical significance. Therefore, the study points to the need for additional research to further evaluate the promise of the constructed response test format.     

PUNISHMENT AS DETERRENCE: REPLY TO SPRAGUE

In my 'A Deterrence Theory of Punishment', I argued that a deterrence system of punishment can avoid the charge that it illegitimately uses offenders if its punishments are carried out 'quasi-automatically': threats are issued by a legislature for deterrent purposes, but those who carry out the punishments have no authority to take deterrent considerations into account. Sprague has objected that under such a system, those who carry out punishments will be unable to justify their actions. I reply that if it is justifiable to set up the system in this way in the first place, then this justification will transmit to all actions carried out under it; and that it is justifiable to set up an institution of punishment in this way.     

PHYSICAL REALISM

Physical realism is the thesis that the world is more or less as present‐day physical theory says it is, i.e. a mind‐independent reality, that consists fundamentally of physical objects that have causal powers, are located in space and time, belong to natural kinds, and interact causally with each other in various natural kinds of ways. It is thus a modern form of physicalism that takes due account of the natural kinds structure of the world. It is a thesis that many present‐day scientific realists would surely accept. Indeed, some might say that physical realism just is scientific realism, but under another name. However, the argument that is presented for physical realism is not the standard one for scientific realism. It is not a two‐stage argument from the success of science to the truth of scientific theories to the reality of the entities postulated in these theories. It is more powerful than this, because it is more direct, and its premisses are more secure. It is more direct, because it develops what is basically a physicalist ontology as the only plausible metaphysical explanation of the new scientific image of the world. It is more secure, in that it does not depend, as the standard argument does, on any doubtful generalisations about the nature or role of scientific theory.     

Unlocking the effects of gender faultlines on team creativity: is activation the key?

The purpose of this study was to use faultline theory to examine the effects of gender diversity on team creativity. Results from 80 teams working on an idea generation task indicated that the activation of gender faultlines negatively affected the number and overall creativity of ideas. However, gender faultlines that were not activated had no effect. Results also indicated that the relationship between activated gender faultlines and team creativity was partially mediated by the level of conflict within the team. Specifically, emotional conflict partially mediated the effects of activated gender faultlines on the number of ideas generated. Implications are discussed, as well as possible limitations and directions for future research.     

Convergence among multiple methods of measuring positivity and negativity in the family environment: relation to depression in mothers and their children

The present study addressed the following questions: (a) To what extent do different methods of measuring the family environment converge onto a single latent construct? (b) How are the constructs of positive and of negative family environment related? (c) Do the associations among various methods of measuring the family environment differ as a function of children's gender or of risk? and (d) How are the latent constructs of family environment related to depression in mothers and their children? Participants were 240 children (mean age = 11.86 years, SD = 0.57) and their mothers, who varied with regard to their history of depression. Family environment was measured with self-report questionnaires completed separately by mothers and by children, observations of mother-child interactions, and a 5-min speech sample of each mother talking about her child. Confirmatory factor analyses revealed that different methods for assessment of the family environment converged and that the constructs of positive and of negative family environments were significantly related to each other and to depression in both mothers and their children. These findings may help inform future intervention efforts by highlighting specific parenting dimensions that are strongly associated with maternal and with child depression.     

Relationship between nicotinic receptors and cognitive function in early Alzheimer's disease: a 2-[18F]fluoro-A-85380 PET study

Neuronal nicotinic acetylcholine receptors (nAChRs) are critical for higher order cognitive processes. Post-mortem studies suggest reductions in nAChRs (particularly the alpha(4)beta(2) subtype) with ageing and in Alzheimer's disease (AD). This study aimed to; (1) quantify nAChR distribution in vivo with 2-[18F]fluoro-A-85380 (2-FA) in 15 early AD patients compared to 14 age-matched, healthy controls (HC) and (2) correlate nAChR distribution with cognitive performance in both groups. All participants were non-smokers and underwent cognitive testing along with a dynamic PET scan after injection of 200 MBq of 2-FA. Brain regional 2-FA binding was assessed through a simplified estimation of Distribution Volume (DV(S)). The AD group differed significantly from HC on all cognitive measures employed, with impairments on measures of attention, working memory, language, executive function, visuospatial ability, verbal learning and verbal memory (p<.05). Contrary to post-mortem data this study found no evidence of in vivo nAChR loss in early AD despite significant cognitive impairment. Furthermore, no correlation between nAChR and cognitive performance was found for either group. The findings of the current study suggest preservation of nAChRs early in AD supporting previous studies. It is possible that while the clinical 2-FA PET method described here may be insensitive in detecting changes in early AD, such changes may be detected in more advanced stages of the illness.     

Bridging the Divide: Linking Basic Science to Applied Psychotherapeutic Interventions—A Relational Frame Theory Account of Cognitive Disputation in Rational Emotive Behavior Therapy

The importance of linking applied psychotherapeutic techniques and strategies to basic experimental science is discussed, both as an independent ideal and in light of non-specific factors research suggesting that atheoretical global factors are responsible for the vast majority of clinical change. As an example of how such basic-applied linkage can occur, principles from Relational Frame Theory and other relevant experimental data are used to analyze and explain the potential utility of two specific strategies often employed in Rational Emotive Behavior Therapy to remediate “awfulizing” and low frustration tolerance, respectively. The preliminary nature of this analysis is highlighted to allow a realistic view of the tremendous task at hand for clinical psychologists seeking a stronger basic science foundation for applied technologies.     

HIV Infection and the Central Nervous System: A Primer

The purpose of this brief review is to prepare readers who may be unfamiliar with Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) and the rapidly accumulating changes in the epidemic by providing an introduction to HIV disease and its treatment. The general concepts presented here will facilitate understanding of the papers in this issue on HIV-associated neurocognitive disorders (HAND). Toward that end, we briefly review the biology of HIV and how it causes disease in its human host, its epidemiology, and how antiretroviral treatments are targeted to interfere with the molecular biology that allows the virus to reproduce. Finally, we describe what is known about how HIV injures the nervous system, leading to HAND, and discuss potential strategies for preventing or treating the effects of HIV on the nervous system.     

Affiliation with new peer acquaintances during two initial social support interactions

Abstract This investigation examined the influence of a prior social support interaction on a subsequent interaction between new peer acquaintances. Pairs of adolescent peers (recruited in a large metropolitan area in the United States) were videotaped as they met and discussed current life concerns in 2 separate interactions. Results indicated that (a) the behaviors of new interaction partners are coordinated within an interaction (social coordination hypothesis), (b) behaviors exhibited during an initial interaction predict behaviors exhibited during a subsequent interaction (influential interaction hypothesis), (c) individuals affiliate in similar ways across interactions (cross‐situational consistency hypothesis), and (d) behaviors reflecting greater comfort with interaction increase across interactions (uncertainty reduction hypothesis). The discussion focuses on implications of results and contributions to existing literatures.
