Does temporal integration of face parts reflect holistic processing?

We examined whether temporal integration of face parts reflects holistic processing or response interference. Participants learned to name two faces “Fred” and two “Bob.” At test, the top and bottom halves of different faces formed composites and were presented briefly separated in time. Replicating prior findings (Singer & Sheinberg, Vision Research, 46, 1838–1847, 2006), naming of the target half for aligned composites was slowed when the irrelevant half was from a face with a different name rather than from the original face. However, no interference was observed when the irrelevant half had a name identical to the name of the target half but came from a different learned face, arguing against a true holistic effect. Instead, response interference was obtained when the target half briefly preceded the irrelevant half. Experiment 2 confirmed a double dissociation of holistic processing versus response interference for intact faces versus temporally separated face halves, suggesting that simultaneous presentation of facial information is critical for holistic processing.     

Error discounting in probabilistic category learning

The assumption in some current theories of probabilistic categorization is that people gradually attenuate their learning in response to unavoidable error. However, existing evidence for this error discounting is sparse and open to alternative interpretations. We report 2 probabilistic-categorization experiments in which we investigated error discounting by shifting feedback probabilities to new values after different amounts of training. In both experiments, responding gradually became less responsive to errors, and learning was slowed for some time after the feedback shift. Both results were indicative of error discounting. Quantitative modeling of the data revealed that adding a mechanism for error discounting significantly improved the fits of an exemplar-based and a rule-based associative learning model, as well as of a recency-based model of categorization. We conclude that error discounting is an important component of probabilistic learning.     

Emotional Health and the Big Five Personality Factors at the American State Level

Relations between the emotional health domain of the Gallup-Healthways Well-Being Index and the Big Five personality factors were determined at the American state level. State emotional health scores were based on the aggregated results of 353,039 phone interviews conducted throughout 2008 with a representative sample of US adults (Gallup 2009a). State z scores (Rentfrow et al. in Perspectives on Psychological Science, 3, 339–386, 2008) on neuroticism, extraversion, agreeableness, conscientiousness, and openness were based on 619,397 nationally representative respondents to an internet survey between 1999 and 2005. State socioeconomic status (SES), urban percent, and white percent based on 2000 and 2005 data served as demographic controls. Alaska and Hawaii were excluded. When the controls entered a hierarchical multiple regression equation as a block and were followed by the Big Five selected stepwise, the controls accounted for 27.5% of the emotional health variance and neuroticism accounted for another 35.3%. With stepwise selection of controls and then Big Five variables, SES entered first (24.1%) and neuroticism entered second (32.4%). With stepwise selection from the combined control and Big Five pool, neuroticism entered first (47.5%), SES entered second (9.1%), and urban percent entered third (4.9%). Clearly, neuroticism and SES are the key contributors to emotional health variance and neuroticism makes the largest contribution. States with higher proportions of neurotic individuals and lower SES tended to have populations with poorer emotional health. Theoretical foundations for the link between neuroticism and emotional health at the state level and implications for changes in state emotional health are discussed.     

Sequential treatment of a feeding problem using a pacifier and flipped spoon

Parents may be reluctant to treat the feeding disorder of a chronically ill child who exhibits distressed behavior during feeding. In this study, we identified a child with chronic medical problems and a feeding disorder who cried during feedings. We introduced treatment components sequentially to address parental concerns about crying. First, we used a pacifier to reduce crying, and then we used a flipped spoon to increase mouth clean. The results showed that a sequential approach to treatment can be effective for children with complex medical and behavioral problems.     

Do state laws concerning homosexuals reflect the preeminence of conservative-liberal individual differences?

The present study was conducted to determine whether individual-level correlates of sexual prejudice (i.e., conservatism-liberalism, religious fundamentalism, educational levels, urbanism, income, and living in the South) are predictive at the state level of laws restricting homosexual behaviors and desires. Criterion 1 was a multifaceted index of state laws concerning gay men and lesbians; Criterion 2 was an index of state laws regarding same-sex partnerships. Multiple regression strategies showed that state conservatism-liberalism, as determined from the responses of 141,798 individuals aggregated at the state level (Erikson, Wright, & McIver, 1993), was the prime state-level predictor of both criteria. For Criterion 1, only Southern state status accounted for additional variance (4.2%) above the 54.8% already accounted for by conservatism-liberalism. For Criterion 2, no other variables accounted for variance beyond the 44.6% accounted for by state conservatism-liberalism.     

Personal goals as predictors of intended classroom goals: Comparing elementary and secondary school pre‐service teachers

Background and Aims. The literature documents fewer classroom mastery goal structures in secondary school compared to elementary. However, little is known about how personal achievement goals may influence classroom goal structures. This is especially true at the level of pre‐service teachers. Our objective was to investigate if pre‐service teachers’ personal goals predicted their intended classroom goal structures. Sample. Participants were 125 elementary and 175 secondary school pre‐service teachers from two Western Canadian universities. Method. Structural equation modelling was used to examine if the structural relationships and latent means of personal and intended classroom goal structures differed for elementary and secondary school pre‐service teachers. Results. The results revealed that personal goals predicted the goal structures that pre‐service teachers intended to establish; however, the relationships and means differed between elementary and secondary school pre‐service teachers. Specifically, personal mastery‐approach goals positively predicted classroom mastery goals much more strongly at the elementary than the secondary level. Furthermore, elementary pre‐service teachers had significantly higher latent mean scores on personal mastery‐approach goals than their secondary counterparts. Conclusions. It seems possible that the currently documented differences between classroom goal structures noted for elementary compared to secondary school may be based on the personal goals endorsed as pre‐service teachers. The results are further discussed in terms of alignment with research on practising teachers’ personal and classroom goals and implications for teacher education.     

A REVIEW OF THE CONTRIBUTION OF PERSONAL CONSTRUCT PSYCHOLOGY TO STAMMERING THERAPY

In the wake of Fransella's (1972) seminal application of Kellyian ideas to the understanding of stammering, the impact of personal construct psychology (PCP) upon speech and language therapists working in this area has been significant. This article reviews the literature and considers the developments in the management of stammering wrought through the application of PCP. A number of key issues relating to the meshing of traditional speech therapy methods and PCP are discussed and these are illustrated further by a specific personal clinical experience.     

Possibilities,models, and intuitionistic logic: Ian Rumfitt’s The boundary stones of thought

AIan Rumfitt's new book presents a distinctive and intriguing philosophy of logic, one that ultimately settles on classical logic as the uniquely correct one–or at least rebuts some prominent arguments against classical logic. The purpose of this note is to evaluate Rumfitt's perspective by focusing on some themes that have occupied me for some time: (i) the role and importance of model theory and, in particular, the place of counter-arguments in establishing invalidity, (ii) higher-order logic, and (iii) the logical pluralism/relativism articulated in my own recent *Varieties of logic*.     

Perspective and prejudice: antecedents and mediating mechanisms

The present work investigated mechanisms by which Whites' prejudice toward Blacks can be reduced (Study 1) and explored how creating a common ingroup identity can reduce prejudice by promoting these processes (Study 2). In Study 1, White participants who viewed a videotape depicting examples of racial discrimination and who imagined the victim's feelings showed greater decreases in prejudice toward Blacks than did those in the objective and no instruction conditions. Among the potential mediating affective and cognitive variables examined, reductions in prejudice were mediated primarily by feelings associated with perceived injustice. In Study 2, an intervention designed to increase perceptions of a common group identity before viewing the videotape, reading that a terrorist threat was directed at all Americans versus directed just at White Americans, also reduced prejudice toward Blacks through increases in feelings of injustice.
