Hemispheric visual atentional imbalance in patients with traumatic brain injury

We find a spatially asymmetric allocation of attention in patients with traumatic brain injury (TBI) despite the lack of obvious asymmetry in neurological indicators. Identification performance was measured for simple spatial patterns presented briefly to a locus 5 degrees into the left or right hemifield, after precuing attention to the same (ipsilateral) or opposite (cross-hemifield) side. Though the cue was non-predictive of target location overall, performance was significantly slower for cross than for ipsilateral trials in both patients and controls. We tested 21 TBI patients without overt focal brain damage and nine control subjects. Only patients demonstrated significantly worse performance for left side presentation in the ipsilateral condition. Furthermore, in the cross-hemifield condition, the left-right difference seen in TBI patients was significantly larger-reflecting a failure in producing a leftward attention shift. Again no significant difference was found in controls. These hemifield effects suggest an asymmetry in the ability of TBI patients in shifting attention to the left hemifield, whether from central fixation or from a cue in the contra-lateral hemifield. The results support basic hypotheses regarding visual attention: Attentional control may be asymmetric and attention may be a distributed, rather than localized cortical function.     

A laboratory-based study of the relationship between childhood abuse and experiential avoidance among inner-city substance users: the role of emotional nonacceptance

Despite the theorized centrality of experiential avoidance in abuse-related psychopathology, empirical examinations of the relationship between childhood abuse and experiential avoidance remain limited. The present study adds to the extant literature on this relationship, providing a laboratory-based investigation of the relationships between childhood sexual, physical, and emotional abuse, experiential avoidance (indexed as unwillingness to persist on 2 psychologically distressing laboratory tasks), and self-reported emotional nonacceptance among a sample of 76 inner-city treatment-seeking substance users. As hypothesized, results provide evidence for heightened experiential avoidance and emotional nonacceptance among individuals with moderate-severe sexual, physical, and emotional abuse (compared to individuals reporting none-low abuse). However, although emotional nonacceptance was associated with increased risk for experiential avoidance, it mediated the relationship between childhood abuse and experiential avoidance only for emotional abuse. As such, results suggest that one mechanism through which emotional abuse in particular leads to experiential avoidance is emotional nonacceptance. Findings suggest the utility of interventions aimed at decreasing experiential avoidance and promoting emotional acceptance among abused individuals.     

An interaction between prosody and statistics in the segmentation of fluent speech

Sensitivity to prosodic cues might be used to constrain lexical search. Indeed, the prosodic organization of speech is such that words are invariably aligned with phrasal prosodic edges, providing a cue to segmentation. In this paper we devise an experimental paradigm that allows us to investigate the interaction between statistical and prosodic cues to extract words from a speech stream. We provide evidence that statistics over the syllables are computed independently of prosody. However, we also show that trisyllabic sequences with high transition probabilities that straddle two prosodic constituents appear not to be recognized. Taken together, our findings suggest that prosody acts as a filter, suppressing possible word-like sequences that span prosodic constituents.     

Fundamental Movement Skills and Children with Attention-Deficit Hyperactivity Disorder: Peer Comparisons and Stimulant Effects

The purpose of this study was to compare the fundamental movement skills of 22 children with attention-deficit hyperactivity disorder (ADHD), from 6 to 12 years of age, to gender- and age-matched peers without ADHD and assess the effects of stimulant medication on the movement skill performance of the children with ADHD. Repeated measures analyses revealed significant skill differences between children with and without ADHD (p ≤ 0.001). Results from the stimulant medication trials indicated no significant effect of medication on the movement skill patterns of children with ADHD. It is concluded that children with ADHD may be at risk for developmental delays in movement skill performance. Potential factors underlying the movement skill difficulties are discussed, with suggestions for future research.     

Gastroesophageal reflux disease: alexithymia and attachment style

Alexithymia and its relation with attachment style were evaluated in a group of 69 patients (men, M age = 46.4 yr., SD = 12.6; women, M age = 44.2 yr., SD = 14.4) affected by Gastroesophageal Reflux Disease. Two self-evaluation questionnaires were used for psychological evaluation, the 20 item Toronto Alexithymia Scale (TAS-20) and the Attachment Style Questionnaire (ASQ). The TAS-20 analysis showed that the clinical sample taken as a whole did not score in the alexithymic range. The inverse correlations between the Confidence ASQ subscale and the Difficulty Communicating Feelings TAS-20 subscale showed that communication of emotions could develop more easily within the framework of a relational context characterized by safety and confidence. In this group of patients this was represented by the referent caregiver.     

Body expressions influence recognition of emotions in the face and voice

The most familiar emotional signals consist of faces, voices, and whole-body expressions, but so far research on emotions expressed by the whole body is sparse. The authors investigated recognition of whole-body expressions of emotion in three experiments. In the first experiment, participants performed a body expression-matching task. Results indicate good recognition of all emotions, with fear being the hardest to recognize. In the second experiment, two alternative forced choice categorizations of the facial expression of a compound face-body stimulus were strongly influenced by the bodily expression. This effect was a function of the ambiguity of the facial expression. In the third experiment, recognition of emotional tone of voice was similarly influenced by task irrelevant emotional body expressions. Taken together, the findings illustrate the importance of emotional whole-body expressions in communication either when viewed on their own or, as is often the case in realistic circumstances, in combination with facial expressions and emotional voices.     

Cross-linguistic differences in the use of durational cues for the segmentation of a novel language

It is widely accepted that duration can be exploited as phonological phrase final lengthening in the segmentation of a novel language, i.e., in extracting discrete constituents from continuous speech. The use of final lengthening for segmentation and its facilitatory effect has been claimed to be universal. However, lengthening in the world languages can also mark lexically stressed syllables. Stress-induced lengthening can potentially be in conflict with right edge phonological phrase boundary lengthening. Thus the processing of durational cues in segmentation can be dependent on the listener’s linguistic background, e.g., on the specific correlates and unmarked location of lexical stress in the native language of the listener. We tested this prediction and found that segmentation by both German and Basque speakers is facilitated when lengthening is aligned with the word final syllable and is not affected by lengthening on either the penultimate or the antepenultimate syllables. Lengthening of the word final syllable, however, does not help Italian and Spanish speakers to segment continuous speech, and lengthening of the antepenultimate syllable impedes their performance. We have also found a facilitatory effect of penultimate lengthening on segmentation by Italians. These results confirm our hypothesis that processing of lengthening cues is not universal, and interpretation of lengthening as a phonological phrase final boundary marker in a novel language of exposure can be overridden by the phonology of lexical stress in the native language of the listener.     

Your goals or mine? Women’s personal and vicarious eating regulation goals and their partners’ perceptions of support,well-being,and relationship quality

This research examined the types of eating regulation goals that women have for themselves as well as for their romantic partner, and how these relate to their interpersonal style toward their partner, and to their partner’s psychological and relational well-being. Participants were 131 heterosexual couples. Results show that the eating regulation goals that women have for their partner (health or appearance oriented) reflect the type of goals that they personally pursue. Furthermore, women who have health-focused eating goals for their partner are perceived as more autonomy-supportive, which is associated with the partner’s report of higher relationship quality. Conversely, women who have appearance-focused eating goals for their partner are more likely to be perceived as controlling, which negatively predicts the partner’s psychological and relational well-being. These results attest to the importance of considering women’s personal eating regulation goals for a better understanding of the type of goals they have for their partners and how these relate to their partners’ well-being and relationship quality.     

Diversifying counsellor education: a case study of U.S. students of colour

Due to limited research on the experiences of students of colour in counselling programmes, counsellor educators are ill-equipped to implement strategies to promote the graduation of students of colour. In this case study, we explored the protective and risk factors for students of colour enrolled in a counselling programme in the Western U.S. Participants identified three protective factors (diversity, faculty support, and family and friends) and three risk factors (balancing family and school, disconnect from programme, and White dominance) that impacted their post-graduate experience. Implications for the retention of students of colour are discussed.
