Research productivity and scholarly impact of APA-accredited school psychology programs: 2005-2009

This study examined the research productivity and scholarly impact of faculty in APA-accredited school psychology programs using data in the PsycINFO database from 2005 to 2009. We ranked doctoral programs on the basis of authorship credit, number of publications, and number of citations. In addition, we examined the primary publication outlets of school psychology program faculties and the major themes of research during this time period. We compared our results with those of a similar study that examined data from a decade earlier. Limitations and implications of this study are also discussed.     

Self-other rating agreement and leader-member exchange (LMX)

Data from a sample of 83 elected community leaders and 391 direct-report staffers (resulting in 306 useable leader-member dyads) were used to test relations between self-other rating agreement of leadership and member-reported leader-member exchange (LMX). Results of polynomial regression analysis indicated that the self-other rating agreement model was not significantly related to member-reported LMX. Instead, virtually all of the variance in member-reported LMX was accounted for by others' ratings.     

Psychometric properties of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) Clinical, Content, and Supplementary scales in a forensic sample

In this study, we evaluated the internal psychometric properties and external correlates of scores on the Clinical, Content, and Supplementary scales in a forensic sample of 496 adolescents (315 boys and 181 girls) who were court-ordered to receive psychological evaluations. We examined Cronbach's alpha coefficients, scale intercorrelation matrices, and frequencies of scale elevations. Further, we found varying degrees of support for the convergent and discriminant validity of scores on the MMPI-A (Butcher et al., 1992 ) Clinical, Content, and Supplementary scales. This study adds to the body of literature establishing the utility of the MMPI-A in forensic evaluations.     

Predicting support for racial transformation policies: Intergroup threat,racial prejudice,sense of group entitlement and strength of identification

Policies and programs designed to challenge the effects of racial discrimination (such as affirmative action) are hotly contested. Factors which have been proposed to explain opposition to these policies include racial prejudice, group threat and self‐interest, and perceptions of intergroup justice. We report the results of two random national telephone surveys which tested a theoretically based model of the predictors of policy support in post‐apartheid South Africa. The results provided limited support for Blumer's group position model. Compensatory and preferential treatment policies had different underlying predictors: Violated entitlement featured in the models of compensatory policy attitudes, but not preferential treatment policy attitudes, where threat was the strongest predictor. In addition to threat and violated entitlement, policy attitudes among the black sample were related to ingroup identification but those of the white sample were related to prejudice. The effects of these variables were in the opposite directions for the two samples: Policy support was associated with strong ingroup identification and high levels of threat among the black sample (i.e. prospective beneficiaries of the transformation policies), but with low levels of prejudice and threat among the white sample. We conclude by considering the implications that these findings have for social change programs. Copyright © 2009 John Wiley & Sons, Ltd.     

Reasoning defeasibly about probabilities

In concrete applications of probability, statistical investigation gives us knowledge of some probabilities, but we generally want to know many others that are not directly revealed by our data. For instance, we may know prob(P/Q) (the probability of P given Q) and prob(P/R), but what we really want is prob(P/Q&;R), and we may not have the data required to assess that directly. The probability calculus is of no help here. Given prob(P/Q) and prob(P/R), it is consistent with the probability calculus for prob(P/Q&;R) to have any value between 0 and 1. Is there any way to make a reasonable estimate of the value of prob(P/Q&;R)? A related problem occurs when probability practitioners adopt undefended assumptions of statistical independence simply on the basis of not seeing any connection between two propositions. This is common practice, but its justification has eluded probability theorists, and researchers are typically apologetic about making such assumptions. Is there any way to defend the practice? This paper shows that on a certain conception of probability—nomic probability—there are principles of “probable probabilities” that license inferences of the above sort. These are principles telling us that although certain inferences from probabilities to probabilities are not deductively valid, nevertheless the second-order probability of their yielding correct results is 1. This makes it defeasibly reasonable to make the inferences. Thus I argue that it is defeasibly reasonable to assume statistical independence when we have no information to the contrary. And I show that there is a function Y(r, s, a) such that if prob(P/Q) = r, prob(P/R) = s, and prob(P/U) = a (where U is our background knowledge) then it is defeasibly reasonable to expect that prob(P/Q&;R) = Y(r, s, a). Numerous other defeasible inferences are licensed by similar principles of probable probabilities. This has the potential to greatly enhance the usefulness of probabilities in practical application.     

The rationality of metaphysics

In this paper, it is argued that metaphysics, conceived as an inquiry into the ultimate nature of mind-independent reality, is a rationally indispensable intellectual discipline, with the a priori science of formal ontology at its heart. It is maintained that formal ontology, properly understood, is not a mere exercise in conceptual analysis, because its primary objective is a normative one, being nothing less than the attempt to grasp adequately the essences of things, both actual and possible, with a view to understanding as far as we can the fundamental structure of reality as a whole. Accordingly, it is urged, the deliverances of formal ontology have a modal and epistemic status akin to those of other a priori sciences, such as mathematics and logic, rather than constituting rivals to the claims of the empirical sciences, such as physics.     

Integrating advice and experience: learning and decision making with social and nonsocial cues

When making decisions, people typically gather information from both social and nonsocial sources, such as advice from others and direct experience. This research adapted a cognitive learning paradigm to examine the process by which people learn what sources of information are credible. When participants relied on advice alone to make decisions, their learning of source reliability proceeded in a manner analogous to traditional cue learning processes and replicated the established learning phenomena. However, when advice and nonsocial cues were encountered together as an established phenomenon, blocking (ignoring redundant information) did not occur. Our results suggest that extant cognitive learning models can accommodate either advice or nonsocial cues in isolation. However, the combination of advice and nonsocial cues (a context more typically encountered in daily life) leads to different patterns of learning, in which mutually supportive information from different types of sources is not regarded as redundant and may be particularly compelling. For these situations, cognitive learning models still constitute a promising explanatory tool but one that must be expanded. As such, these findings have important implications for social psychological theory and for cognitive models of learning.     

System justification and the defense of committed relationship ideology

A consequential ideology in Western society is the uncontested belief that a committed relationship is the most important adult relationship and that almost all people want to marry or seriously couple (DePaulo & Morris, 2005). In the present article, we investigated the extent to which the system justification motive may contribute to the adoption of this ideology. In Studies 1 and 2, we examined whether a heightened motive to maintain the status quo would increase defense of committed relationship values. In Study 3, we examined the reverse association, that is, whether a threat to committed relationship ideology would also affect sociopolitical system endorsement. As past research has found that the justification of political systems depends upon how much these systems are perceived as controlling, in Study 4 we tested whether the defense of the system of committed relationships would also increase when framed as controlling. Results from Studies 1-4 were consistent with our hypotheses, but only for men. In Study 5, using cross-cultural data, we sought to replicate these findings correlationally and probe for a cause of the gender effect. Results from more than 33,000 respondents indicated a relationship (for men) between defense of the sociopolitical system and defense of marriage in countries where the traditional advantages of men over women were most threatened. In Studies 6 and 7, we investigated when this gender difference disappears. Results revealed that when we measured (Study 6) or manipulated (Study 7) personal relationship identity rather than relationship ideology, effects also emerge for women.     

Role of serial order in the impact of talker variability on short-term memory: testing a perceptual organization-based account

In two experiments, we examined the impact of the degree of match between sequential auditory perceptual organization processes and the demands of a short-term memory task (memory for order vs. item information). When a spoken sequence of digits was presented so as to promote its perceptual partitioning into two distinct streams by conveying it in alternating female (F) and male (M) voices (FMFMFMFM)—thereby disturbing the perception of true temporal order—recall of item order was greatly impaired (as compared to recall of item identity). Moreover, an order error type consistent with the formation of voice-based streams was committed more quickly in the alternating-voice condition (Exp. 1). In contrast, when the perceptual organization of the sequence mapped well onto an optimal two-group serial rehearsal strategy—by presenting the two voices in discrete clusters (FFFFMMMM)—order, but not item, recall was enhanced (Exp. 2). The results are consistent with the view that the degree of compatibility between perceptual and deliberate sequencing processes is a key determinant of serial short-term memory performance. Alternative accounts of talker variability effects in short-term memory, based on the concept of a dedicated phonological short-term store and a capacity-limited focus of attention, are also reviewed.
