Higher order influences on evaluative priming: Processing styles moderate congruity effects

A growing body of research challenges the automaticity of evaluative priming (EP). The present research adds to this literature by suggesting that EP is sensitive to processing styles. We relied on previous research showing that EP is determined by the extent to which the prime and the target events on a given trial are processed as a unified compound. Here, we further hypothesised that processing styles encouraging the inclusion of the prime to the target episode support congruity effects, whereas processing styles that enhance the exclusion of the prime from the target episode interrupt (or reverse) these effects. In Experiment 1, a preceding similarity search task produced a congruity effect, whereas a dissimilarity search task eliminated and (non-significantly) reversed this effect. In Experiments 2 and 3, we replicated and extended these findings using a global/local processing manipulation. Overall, these findings confirm that EP is flexible, open to top-down influences and strategic regulation.     

Ethnic Diversity and Differential Policing in Australia: the Good, the Bad and the Ugly

This paper focuses on three models of policing that have variously been exercised in relation to ethnic minority young people in Australia. As part of this, the paper critically explores policing that is primarily based upon coercion (‘the bad’), and, at its worst, explicitly discriminatory forms of zero tolerance (‘the ugly’), and compares these with police interventions that favour a more constructive and positive community-based approach (‘the good’). The paper provides a comprehensive review of literature on police–ethnic minority youth relations in the Australian context, as well as indicating recent strategic developments within police services around the country.     

On splitting and merging categories: A regression account of subadditivity

Frequency judgments tend to be subadditive: A category’s frequency is judged to be lower than the summed frequency of its subcategories. Thus, by splitting or merging categories, subjective frequencies increase or decrease, respectively. We offer an account of this phenomenon that is based on the statistical principle of regression. Because empirical information is never noise-free, high frequencies are underestimated, and low frequencies are overestimated. The underlying regression principle explains available evidence on subadditivity and allows novel predictions. The findings from two experiments supported predictions derived from the regression account of frequency estimates for split and merged categories: Subadditivity varied systematically as a function of the two parameters determining regression (extremity and reliability). More extreme frequencies and reduced reliability led to increased regression effects. Theoretical implications for subadditive judgments (of frequency, probability, and/or value) are discussed. Although other factors may contribute to subadditivity, their influence needs to exceed the baseline expected from the regression model alone.     

The Influence of Affective and Instrumental Beliefs on Exercise Intentions and Behavior: A Longitudinal Analysis

Programs encouraging exercise might reduce coronary illness. Ajzen's theory of planned behavior is a useful model for understanding exercise motivation. The current study investigated the contribution of the instrumental and affective components of attitude. As part of a community-based study of exercise behavior, 424 men and 572 women completed questionnaires, with 365 participants providing 6-month follow-up data. Regressions highlighted the affective component as a much more powerful predictor of intention compared to the instrumental component. After controlling for prior exercise, intention was not predictive of later exercise, although the affective component was. The implications for exercise promotion are discussed.     

The ultimate sampling dilemma in experience-based decision making

Computer simulations and 2 experiments demonstrate the ultimate sampling dilemma, which constitutes a serious obstacle to inductive inferences in a probabilistic world. Participants were asked to take the role of a manager who is to make purchasing decisions based on positive versus negative feedback about 3 providers in 2 different product domains. When information sampling (from a computerized database) was over, they had to make inferences about actual differences in the database from which the sample was drawn (e.g., about the actual superiority of different providers, or about the most likely origins of negatively valenced products). The ultimate sampling dilemma consists in a forced choice between 2 search strategies that both have their advantages and their drawbacks: natural sampling and deliberate sampling of information relevant to the inference task. Both strategies leave the sample unbiased for specific inferences but create errors or biases for other inferences.     

Teaching Beginning Braille Reading Using an Alphabet or Uncontracted Braille Approach

This study examined the effects of using a research based print reading program modified to accommodate beginning braille readers using an alphabet or uncontracted braille reading approach with five beginning braille readers. Four of the 5 participants displayed a clear increase in their ability to read high frequency words when they began using the Early Steps reading program modified to an Early Steps Alphabet Braille Reading Program. Study findings indicate that access to reading activities and materials afforded to sighted peers resulted in improved reading outcomes for children with visual impairments. Teachers, participants, and family members all viewed the use of the uncontracted braille reading program and materials favorably. Specialized reading instruction was also perceived as beneficial by teachers of students with visual impairments when the training addressed the specific needs of braille readers.     

Metacognitive myopia and the overutilization of misleading advice

Previous research on advice taking has explained the failure to exploit collective wisdom in terms of the egocentric underweighting of advice provided by independent others. The present research is concerned with an opposite and more radical source of irrational advice taking, namely, the failure to critically assess the validity of advice due to metacognitive myopia. Participants could use the advice of one or two experts when estimating health risks. They read sketches of the study samples that experts had drawn to estimate conditional probabilities (e.g., of HIV‐given drug addiction). Whether samples were valid or seriously biased, subsequent judgments were strongly affected by any advice (Experiment 1). Uncritical reliance on any advice persisted when participants were sensitized to the contrast of valid and invalid advice in a repeated measures design (Experiment 2), when participants themselves believed advice not to be valid (Experiment 3), and even after full debriefing about invalid advice (Experiment 4). Lay advice exerted a similar influence as expert advice (Experiment 5). Although these provocative results are independent of numeracy and consensus (Experiment 6), they highlight the impact of metacognitive myopia as an impediment of social rationality.     

Visual object affordances: object orientation

Five experiments systematically investigated whether orientation is a visual object property that affords action. The primary aim was to establish the existence of a pure physical affordance (PPA) of object orientation, independent of any semantic object-action associations or visually salient areas towards which visual attention might be biased. Taken together, the data from these experiments suggest that firstly PPAs of object orientation do exist, and secondly, the behavioural effects that reveal them are larger and more robust when the object appears to be graspable, and is oriented in depth (rather than just frontally) such that its leading edge appears to point outwards in space towards a particular hand of the viewer.     

Effectiveness of a trauma/grief-focused group intervention: a qualitative study with war-exposed Bosnian adolescents

The effectiveness and impacts of a school-based, trauma/grief-focused group treatment program for war-exposed youth in Bosnia and Herzegovina were investigated using semistructured focus groups, conducted separately for students and their school counselor group leaders. Overall, students' and leaders' evaluations of the groups were generally positive. General themes of outcomes and impacts perceived by students and group leaders include: acquisition of coping skills and attitudes, willingness to advocate for peers, improved interpersonal relationships, negative impacts, general positive impacts, impacts in the schools, impacts on the group and logistics of the program, and broader impacts on the perception of mental health in the community. The broad positive impacts of this program suggest that trauma/grief-focused group treatment intervention programs targeting trauma-exposed youth may be effective on multiple levels with war-exposed youth and their communities.     

Locus of the intensity effect in simple reaction time tasks

Evidence is still inconclusive regarding the locus of the stimulus intensity effect on information processing in reaction tasks. Miller, Ulrich, and Rinkenauer (1999) addressed this question by assessing the intensity effect on stimulus- and response-locked lateralized readiness potentials (LRPs) as indices of the sensory and motor parts of reaction time (RT). In the case of visual stimuli, they observed that application of brighter stimuli resulted in a shortening of RT and stimulus-locked LRP (S-LRP), but not of response-locked LRP (R-LRP). The results for auditory stimuli, however, were unclear. In spite of a clear RT reduction due to increased loudness, neither S-LRP nor R-LRP onset was affected. A reason for this failure might have been a relatively small range of intensity variation and the type of task. To check for this possibility, we performed three experiments in which broader ranges of stimulus intensities and simple, rather than choice, response tasks were used. Although the intensity effect on the R-LRP was negligible, S-LRP followed RT changes, irrespective of stimulus modality. These findings support the conclusion that stimulus intensity exerts its effect before the start of motoric processes. Finally, S-LRP and R-LRP findings are discussed within a broader information-processing perspective to check the validity of the claim that S-LRP and R-LRP can, indeed, be considered as pure estimates of the duration of sensory and motor processes.
