Why does selective attention to parts fail in face processing?

One hallmark of holistic face processing is an inability to selectively attend to 1 face part while ignoring information in another part. In 3 sequential matching experiments, the authors tested perceptual and decisional accounts of holistic processing by measuring congruency effects between cued and uncued composite face halves shown in spatially aligned or disjointed configurations. The authors found congruency effects when the top and bottom halves of the study face were spatially aligned, misaligned (Experiment 1), or adjacent to one another (Experiment 2). However, at test, congruency effects were reduced by misalignment and abolished for adjacent configurations. This suggests that manipulations at test are more influential than manipulations at study, consistent with a decisional account of holistic processing. When encoding demands for study and test faces were equated (Experiment 3), the authors observed effects of study configuration suggesting that, consistent with a perceptual explanation, encoding does influence the magnitude of holistic processing. Together, these results cannot be accounted for by current perceptual or decisional accounts of holistic processing and suggest the existence of an attention-dependent mechanism that can integrate spatially separated face parts.     

Parental involvement in competitive youth sport settings

ObjectivesBased on ecological systems theory [Bronfenbrenner, U. (2005). Making human beings human: Bioecological perspectives on human development. Thousand Oaks, CA: Sage], the purpose of this study was to examine parents’ involvement in competitive youth sport settings.DesignData were collected through two distinct phases of fieldwork. Phase 1 involved longitudinal data collection with four families. Phase 2 involved observations of youth soccer settings.MethodData were collected from four families via individual interviews and audio-diaries and were supplemented through 120 h of observation. Data were transcribed verbatim and analyzed using grounded theory methodology.ResultsParents’ verbal reactions to their children's sport performance behaviors were placed on a continuum moving from more supportive to more controlling comments. These comments were categorized as praise/encouragement, performance contingent feedback, instruction, striking a balance, negative comments, and derogatory comments. Parents experienced empathy in that they perceived sharing the emotions their children felt in sport, and these emotions appeared to change in relation to dynamic game and contextual circumstances. Parents also thought that they possessed knowledge and expertise of sport, which they perceived enabled them to make comments to their children.ConclusionA series of reciprocal and bi-directional relationships were central to parents’ involvement in competitive youth sport.     

Investigating models of affect: relationships among EEG alpha asymmetry, depression, and anxiety

The approach-withdrawal and valence-arousal models both predict that depressive and anxious profiles will be associated with relatively reduced left frontal and increased right frontal activity respectively, while the valence-arousal model also proposes a dissociation by lower and higher right parietotemporal activity, respectively. Recent work further suggests that subtypes of anxiety disorders may be characterized by distinctive patterns of activity depending on their type of arousal (anxious arousal/apprehension). The aim of this study was to investigate the relationships among nonclinical depression/anxiety and lateralized frontal/parietotemporal activity by categorizing participants (N=428) on the basis of both negative mood and alpha EEG. Key findings include: (i) greater right frontal lateralization in anxious participants, symmetrical frontal activity in depressed/comorbid, and left frontal lateralization in healthy controls; (ii) right frontal lateralization in anxious arousal participants, left frontal and right parietotemporal lateralization in anxious apprehension; (iii) bilateral increase in frontal and increased right parietotemporal activity in depressed/comorbid participants. Findings support predictions for frontal but not posterior regions. Grouping on the basis of EEG may not be reciprocally predictive of negative mood groupings, suggesting involvement of additional factors.     

Attachment and empathy as predictors of roles as defenders or outsiders in bullying interactions

Bullying almost always occurs in the presence of peers, most of whom do not intervene to stop it. This study examined the role of attachment, empathy, and gender in predicting the behavior of 105 middle school students who reported being either (a) defenders who actively intervened to stop bullying, or (b) outsiders who were either not involved or stood by passively. It was hypothesized that gender, attachment to mother, attachment to father, and empathy would predict whether children nominated themselves as defenders in bullying situations. A hierarchical logistic regression analysis indicated that these variables together significantly predicted whether children nominated themselves as defenders or outsiders. Gender was not a unique significant predictor. Attachment to mother contributed significant unique variance to the model, but attachment to father did not after accounting for gender and attachment to mother. Empathy contributed significant unique variance to the model even after accounting for all other variables. Results suggest that middle school personnel should openly discuss with students their roles in bullying interactions. In addition, teaching empathy towards others and involving parents may be critical components in comprehensive prevention programs.     

Using mediational models to explore the nature of tobacco motivation and tobacco treatment effects

Various theories have proposed mechanisms for drug motivation and relapse. For instance, negative reinforcement theories focus on the alleviation of withdrawal. However, other theories and some data cast doubt on the importance of withdrawal as a motivator of addictive drug use. Using data from a randomized double-blind placebo-controlled smoking cessation treatment study (N=608), this research examined the impact of withdrawal on drug motivation and the ability to maintain abstinence. Withdrawal was experimentally manipulated by randomly assigning participants to receive active bupropion versus placebo. Mediation analyses revealed that active bupropion reduced the amount of withdrawal and craving that individuals reported in the 1st week post quit; modest support was also found for smaller declines in positive affect. These effects, in turn, were all positively associated with posttreatment abstinence. These results implicate withdrawal as an important factor in motivating persistent tobacco use.     

Choosing a Place of Death: The Influence of Pain and of Attitude Toward Death1

This experimental study sought to verify if factors like pain or attitude toward death can determine the choice of a place of death. Using a questionnaire developed from Triandis’(1980) theory, the influence of pain on the intention of choosing a place of death was measured among 138 respondents. “Attitude toward death,” used as a control variable, was measured by means of the Death Attitude Profile. Variance analyses (p < .008) demonstrated the influence of pain on intention of choosing a place of death and on the cognitive component. Linear regression (p .002) highlighted 2 determinants of intention of choosing a place of death: moral norm and social role. As for attitude toward death, it seems to have no influence on the choice of a place of death.     

Visuo‐spatial abilities in autism: A review

Individuals with autism show various signs of heightened abilities in visuo‐spatial functioning. First, it is long‐established that they excel on embedded figures and block design tests relative to comparison participants. Second, some evidence suggests that processing global features is affected by inappropriate processing of the constituent elements of a stimulus. Third, they are more accurate than comparison participants in judging the shape of a slanted circle in a context in which ambient visual cues are eliminated. This suggests that their perception of the shape is less influenced by prior knowledge. Fourth, they are fast at searching for feature and conjunctive targets in a visual array. Contrary to earlier reports, however, they are susceptible to visual illusions. Also, they do show evidence of utilising prior knowledge when pairing a colour with an atypically coloured target. Accordingly, we conclude that there is something distinctive about autistic visuo‐spatial functioning, but not necessarily in ways that are predicted by the ‘weak central coherence’ hypothesis.

Using latent semantic analysis to assess reader strategies

We tested a computer-based procedure for assessing reader strategies that was based on verbal protocols that utilized latent semantic analysis (LSA). Students were given self-explanation—reading training (SERT), which teaches strategies that facilitate self-explanation during reading, such as elaboration based on world knowledge and bridging between text sentences. During a computerized version of SERT practice, students read texts and typed self-explanations into a computer after each sentence. The use of SERT strategies during this practice was assessed by determining the extent to which students used the information in the current sentence versus the prior text or world knowledge in their self-explanations. This assessment was made on the basis of human judgments and LSA. Both human judgments and LSA were remarkably similar and indicated that students who were not complying with SERT tended to paraphrase the text sentences, whereas students who were compliant with SERT tended to explain the sentences in terms of what they knew about the world and of information provided in the prior text context. The similarity between human judgments and LSA indicates that LSA will be useful in accounting for reading strategies in a Web-based version of SERT.
