Minority stress,substance use,and intimate partner violence among sexual minority women

Compared to the research literature on intimate partner violence (IPV) in heterosexual relationships, our understanding of IPV among sexual minority women (SMW) lags far behind. This paper reviews the literature regarding the prevalence of IPV among SMW and discusses disparities between SMW and heterosexual women. Methodological issues in this area are also discussed. Moreover, we review associations among substance use, sexual minority stress, and IPV in this population. Finally, potential protective factors, such as social and community support, identity, mastery, and coping, are examined. As researchers and clinicians work to improve the health of SMW it is important to consider the associations among relationship violence, substance use, and minority stress. Moreover, it is essential to understand what factors may promote adjustment among SMW.     

Different cues of personality and health from the face and gait of women

Redundant cues for attractiveness in humans have been identified, but the idea of multiple systems displaying different socially-relevant traits has yet to be extensively examined. We compared the accuracy with which observers could identify socially-relevant information of female targets, both from static images of their faces, and from point-light displays of their gait. Perception of extraversion was at chance. However, agreeableness and sociosexuality were more accurately perceived from the face than gait, while physical health showed the opposite pattern. This double dissociation suggests different information can be carried in different modalities. In addition, partial correlation analyses suggested that even when both modalities allowed accurate trait identification, the information content was different. Our results demonstrate that cues of different socially-relevant traits are communicated more effectively through different modalities, and these modality-specific cues contain distinctive information, supporting a "multiple messages" hypothesis.     

Social Anxiety and Content Specificity of Interpretation and Judgemental Bias in Children

Previous research with adult samples has demonstrated that social anxiety disorder is associated with content‐specific interpretation and judgemental biases. The present study extends our understanding of the specificity of cognitive biases in childhood social anxiety. A sample of non‐clinical children aged 11–12 years completed social anxiety and depression scales and was presented with scenarios depicting hypothetical events varying along two dimensions: relevance to self (event occurs to self or to other) and domain of activity (event is social or non‐social). Partial support for the content‐specificity hypothesis was found. Children's social anxiety symptoms were positively associated with negative interpretation ratings for ambiguous self‐referent and other‐referent events, but only when these events were in the social domain. Further, children's social anxiety symptoms were positively associated with emotional cost judgements for ambiguous social and non‐social events, but only when these events referred to the self. Both patterns of results remained significant even after controlling for concurrent depressive symptoms. Implications of the results for our understanding of maintaining factors in childhood social anxiety are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Prefrontal cortex dysfunction and ‘Jumping to Conclusions’: Bias or deficit?

The 'beads task' is used to measure the cognitive basis of delusions, namely the 'Jumping to Conclusions' (JTC) reasoning bias. However, it is not clear whether the task merely taps executive dysfunction - known to be impaired in patients with schizophrenia - such as planning and resistance to impulse. To study this, 19 individuals with neurosurgical excisions to the prefrontal cortex, 21 unmedicated adults with Attention Deficit Hyperactivity Disorder (ADHD), and 25 healthy controls completed two conditions of the beads task, in addition to tests of memory and executive function as well as control tests of probabilistic reasoning ability. The results indicated that the prefrontal lobe group (in particular, those with left-sided lesions) demonstrated a JTC bias relative to the ADHD and control groups. Further exploratory analyses indicated that JTC on the beads task was associated with poorer performance in certain executive domains. The results are discussed in terms of the executive demands of the beads task and possible implications for the model of psychotic delusions based on the JTC bias.     

My Child Is Better Than Average: The Extension and Restriction of Unrealistic Optimism1

The purpose of the current study was to determine whether parents make unrealistic evaluations of children and what factors predict these evaluations. Parents of 5‐ and 6‐year‐olds rated their child's risk for various positive and negative outcomes, temperament, and health and behavior problems. Parents also completed an adult attachment measure. Parents appeared to give relatively little consideration to realistic constraints when predicting their child's future. Parents scoring higher on attachment avoidance were less optimistic that their child would attain positive outcomes and avoid negative outcomes, consistent with the view that optimism is a motivated phenomenon. Greater child internalizing behaviors also were associated with less parental optimism for positive outcomes. Findings have implications for the delivery of health messages to parents.     

Dual-Element Effects in Pigeons’ Matching-to-Sample with Temporal and Visual Stimuli

The present study examined whether the dual-element effect occurs when temporal and visual stimuli appear simultaneously in a zero-delayed, symbolic matching-to-sample task. Two groups of pigeons were first exposed to either a red or green sample stimulus, for either 30 s or 5 s. The sample was followed by the presentation of yellow and blue comparisons. For pigeons in one group, the duration of the sample was the relevant cue. Responses to the yellow comparison were reinforced if the sample was 30 s, and responses to the blue comparison were reinforced if the sample was 5 s. For the other group, sample duration was irrelevant. Responses to the yellow comparison were reinforced if the sample had been green and responses to the blue comparison were reinforced if the sample had been red. Both groups then learned a second matching task in which the sample and comparison stimuli were vertical and horizontal lines. Finally, matching performance was examined when the lines appeared together with the temporal or color elements. The results showed that the line matching task was acquired more slowly for pigeons that were first trained to attend to duration. More importantly, matching was reduced when the temporal and line elements appeared simultaneously, and the effects were similar to those obtained when visual elements are combined.

     

A processing model for the analysis of one-way arguments in discourse

This paper describes a computational model for analyzing arguments in discourse. In particular, the model describes processes necessary for interpreting one uninterrupted argument from a speaker. The resulting output is a representation for the underlying claim and evidence relations between propositions of the argument. For our processing model we present: (i) a characterization of coherent orderings of propositions, used to limit search for interpretation of each new proposition (ii) a working definition of the evidence relation, used to recognize connections between propositions (iii) a theory of the function and use of clue words — special words and phrases indicating the structure of the argument — then used in the analysis to control search for interpretation and verification of evidence relations.
