Hand dominance influences the processing of observed bodies

In motor tasks, subgroups of lefthanders have been shown to differ in the distribution of attention about their own bodies. The present experiment examined whether similar attentional biases also apply when processing observed bodies. Sixteen right handers (RHs), 22 consistent left handers (CLHs) and 11 relatively ambidextrous inconsistent left handers (ILHs) performed an own body transformation task in which they were instructed to make speeded left–right judgements about a schematic human figure. Attentional biases associated with handedness were found to extend to observed bodies: CLHs’ judgements were faster to the figure’s left side, while ILHs, like RHs, showed facilitated performance to the figure’s right side. These results demonstrate a novel embodiment effect whereby the processing of a static schematic human figure is modulated by an individual’s personal motor capabilities. This finding suggests that motor simulation may contribute to whole body perception in the absence of actual or implied actions.     

Functional characterisation of the extrastriate body area based on the N1 ERP component

Electrophysiological and functional neuroimaging evidence points to the existence of neural populations that respond strongly and selectively to the appearance of the human body and its parts. However, the relationship between ERP and fMRI markers of these populations remains unclear. Here we used a previously identified functional dissociation between two body-selective regions identified with fMRI (extrastriate body area or EBA; fusiform body area or FBA) in order to better understand the source of a body-selective N1 ERP component. Specifically, we compared the magnitude of the N1 elicited by images of fingers, hands, arms and bodies to that obtained for hierarchically-matched control stimuli. We found close agreement between the pattern of body-part selectivity exhibited by N1, and the pattern of BOLD selectivity elicited in a previous study by the same type of stimuli in EBA (in contrast to FBA). We interpret these findings as evidence for EBA as the primary generator of the body-selective N1 component. Our results are an example of the use of functional criteria to distinguish among the possible neural sources of ERP markers.     

Relationship of Ethnic Identity,Acculturation, and Psychological Well‐Being Among Chinese,Japanese, and Korean Americans

The current investigation examined the relationship of ethnic identity, acculturation, and psychological functioning among 334 Chinese, Japanese, and Korean American participants. Multiple regression analyses revealed that ethnic identity and acculturation differentially predicted well‐being on the basis of ethnic group membership. Results also indicated that a bicultural worldview was positively associated with psychological well‐being. Implications for counseling and recommendations for future research are discussed.     

Measuring “intuition” in the SRT generation task

We address some concerns related to the use of post-trial attribution judgments, originally developed for artificial grammar learning (AGL), during the version of the serial reaction time (SRT) task used by Fu, Dienes, and Fu (2010). In particular, intuition attributions, which are central to Fu et al.’s arguments, seem problematic: This attribution is likely to be made when stimuli contain several competing sources of information to which subjective feelings could be attributed. The interpretation of intuition attributions in Fu et al.’s SRT generation task is problematic because the procedure involved a 2-element sequence where items varied only in position. In our view, responses categorised as intuitions might have been a variety of guess response where neither judgement knowledge nor structural knowledge were conscious. The results would then be compatible with previous findings showing that people can control the use of unconscious structural knowledge even when judgement knowledge is unconscious.     

The community substance use environment: The development and predictive ability of a multi‐method and multiple‐reporter measure

This study tested the feasibility and utility of developing a multiple‐method and multiple‐reporter measure that describes the community substance use environment. Data on community‐level norms and availability of substances were reported by 5261 students and 181 prevention‐focused community leaders (CL) involved in the 28 promoting school–university–community partnerships to enhance resilience (PROSPER) Project communities between 2002 and 2005. Additionally, locations of alcohol and tobacco outlets were geocoded. Initially, these four subscales were aggregated to measure the community substance use environment. Analyses demonstrated this measure was associated with community rates of adolescent reported cigarette use, but it was not associated with community rates of adolescent reported alcohol use. Further analyses tested the relative strength of the four different subscales in predicting rates of student use. Implications of these results for the field of community‐based prevention are discussed, as well as limitations and future directions. Copyright © 2009 John Wiley & Sons, Ltd.     

Group Art Therapy With Incarcerated Women

Art therapy in groups with incarcerated individuals may be effective when participants are defensive and possess limited education. The authors provide procedures, techniques, and case examples from the New Beginnings program for working with women in a detention facility.     

Perceived Parenting,Self-Esteem,and General Self-Efficacy of Iranian American Adolescents

We examined whether Iranian American adolescents’ perceptions of parental support, parental knowledge, and parental psychological control relate to general self-efficacy directly, and indirectly through positive esteem and self-deprecation. To investigate this, self-report surveys were collected from 158 Iranian American adolescents attending Iranian American youth groups, Armenian private school, and one public school. Results indicated that positive esteem, self-deprecation, mother and father knowledge, and mother and father psychological control were directly related to general self-efficacy. Furthermore, the parenting variables were indirectly related to general self-efficacy through either positive esteem or self-deprecation.     

Relationships of parents’ and child’s general attributional styles to academic performance

This study examined the relationships among student academic performance and child’s and parents’ attributional styles. One hundred seventy-nine students (87 boys and 92 girls) who were enrolled in primary public schools in New South Wales, Australia, and their parents volunteered to participate in the study. Only English-speaking, two-parent families were included. Participants completed age-appropriate attributional style questionnaires. Academic performance was obtained from student records of course grades. The results indicated that both mothers’ and fathers’ attributions for their own positive and negative life events were related to their children’s attributions for their academic performance. We present implications of these results for research on attributions and academic performance.     

Pupil diameter tracks changes in control state predicted by the adaptive gain theory of locus coeruleus function

An important dimension of cognitive control is the adaptive regulation of the balance between exploitation (pursuing known sources of reward) and exploration (seeking new ones) in response to changes in task utility. Recent studies have suggested that the locus coeruleus-norepinephrine system may play an important role in this function and that pupil diameter can be used to index locus coeruleus activity. On the basis of this, we reasoned that pupil diameter may correlate closely with control state and associated changes in behavior. Specifically, we predicted that increases in baseline pupil diameter would be associated with decreases in task utility and disengagement from the task (exploration), whereas reduced baseline diameter (but increases in task-evoked dilations) would be associated with task engagement (exploitation). Findings in three experiments were consistent with these predictions, suggesting that pupillometry may be useful as an index of both control state and, indirectly, locus coeruleus function.     

A validation of well-being and happiness surveys for administration via the Internet

Internet research is appealing because it is a cost- and time-efficient way to access a large number of participants; however, the validity of Internet research for important subjective well-being (SWB) surveys has not been adequately assessed. The goal of the present study was to validate the Satisfaction With Life Scale (SWLS; Diener, Emmons, Larsen, & Griffin, 1985), the Positive and Negative Affect Schedule (PANAS-X; Watson & Clark, 1994), and the Subjective Happiness Scale (SHS; Lyubomirsky & Lepper, 1999) for use on the Internet. This study compared the quality of data collected using paper-based (paper-and-pencil version in a lab setting), computer-based (Web-based version in a lab setting), and Internet (Web-based version on a computer of the participant’s choosing) surveys for these three measures of SWB. The paper-based and computer-based experiment recruited two college student samples; the Internet experiments recruited a college student sample and an adult sample responding to ads on different social-networking Web sites. This study provides support for the reliability, validity, and generalizability of the Internet format of the SWLS, PANAS-X, and SHS. Across the three experiments, the results indicate that the computer-based and Internet surveys had means, standard deviations, reliabilities, and factor structures that were similar to those of the paper-based versions. The discussion examines the difficulty of higher attrition for the Internet version, the need to examine reverse-coded items in the future, and the possibility that unhappy individuals are more likely to participate in Internet surveys of SWB.
