The patterns of silence: Performance structures in sentence production

The pauses produced by speakers while reading familiar material were used to obtain hierarchical sentence structures. Identical structures were obtained from parsing, indicating that the performance structures of sentences are not task specific. The linguistic surface structure of a sentence is a good predictor of the pause durations. However, speakers also revealed a tendency to place pauses between segments of equal length. A simple cyclical model combining, for each pause location, an index of linguistic complexity and a measure of the distance to the midpoint of the segment, accounts for 72% of the pause time variance as opposed to 56% for the linguistic index alone. The generality of the model is shown by its good prediction of the pause durations obtained in unrelated studies in English and American Sign Language.     

Cerebral asymmetry for American Sign Language: The effects of moving stimuli

Previous studies of cerebral asymmetry for the perception of American Sign Language (ASL) have used only static representations of signs; in this study we present moving signs. Congenitally deaf, native ASL signers identified moving signs, static representations of signs, and English words. The stimuli were presented rapidly by motion picture to each visual hemifield. Normally hearing English speakers also identified the English words. Consistent with previous findings, both the deaf and the hearing subjects showed a left-hemisphere advantage to the English words; likewise, the deaf subjects showed a right hemisphere advantage to the statically presented signs. With the moving signs, the deaf showed no lateral asymmetry. The shift from right dominance to a more balanced hemispheric involvement with the change from static to moving signs is consistent with Kimura's position that the left hemisphere predominates in the analysis of skilled motor sequencing (Kimura 1976). The results also indicate that ASL may be more bilaterally represented than is English and that the spatial component of language stimuli can greatly influence lateral asymmetries.     

Gradients of auditory generalization for blind, retarded children

Severely retarded, blind children were conditioned to respond differentially to two intensities of a pure tone. Gradients of auditory generalization were obtained that were reliable and similar to those for normal adults, but often asymmetric and non-monotonic.     

Comorbid anxiety and mood disorders among persons with social anxiety disorder.

Axis I comorbidity is associated with greater severity of social anxiety disorder. However, the differential effects of comorbid mood and anxiety disorders on symptom severity or treatment outcome have not been investigated. We evaluated 69 persons with uncomplicated social anxiety disorder, 39 persons with an additional anxiety disorder, and 33 persons with an additional mood disorder (with or without additional anxiety disorders). Those with comorbid mood disorders reported greater duration of social anxiety than those with uncomplicated social anxiety disorder. They were also judged, before and after 12 weeks of cognitive-behavioral group treatment and at follow-up, to be more severely impaired than those with no comorbid diagnosis. In contrast, persons with comorbid anxiety disorders were rated as more impaired than those with no comorbid diagnosis on only a single measure. Type of comorbid diagnosis did not result in differential rates of improvement of social anxiety disorder.     

Assessing Client Progress Session by Session in the Treatment of Social Anxiety Disorder: The Social Anxiety Session Change Index

Frequent assessment during therapy can improve treatments and provide accountability. However, clinicians often do not monitor progress because of the time it takes to administer and score assessments. In response, the Social Anxiety Session Change Index (SASCI) was developed. The SASCI is a short, easily administered rating of subjective improvement that asks clients with social anxiety disorder how much they have changed since the beginning of therapy. Change on the SASCI was related to change in fear of negative evaluation, a core aspect of social anxiety, and to clinician-rated improvement, but not to ratings of anxiety sensitivity or depression. Because it is brief and easily interpretable, the SASCI can be used in a variety of clinical settings to monitor change across therapy. The SASCI is presented along with examples of how the information gathered from frequent administration can inform clinical practice.     

Should we suppress or reappraise our stress?: the moderating role of reappraisal on cortisol reactivity and recovery in healthy adults

Background: People differ in their ability to regulate their physiological stress response. Individual differences in emotion regulation strategies such as suppression and reappraisal may explain this differential response to stress.

Objective: The aim of the current study was to assess whether daily use of suppression and reappraisal as well as their interaction predicted physiological stress reactivity and/or recovery, as assessed by variations in cortisol levels.

Method: Thirty-eight healthy young adults (13 men) completed the Emotion Regulation Questionnaire and were exposed to a psychosocial stressor, throughout which salivary cortisol was measured.

Results: Linear regressions showed main effects of reappraisal and suppression on cortisol reactivity and a main effect of suppression on cortisol recovery, where both strategies were positively associated with stress phases. Moreover, results showed a significant interaction of suppression by reappraisal in predicting both cortisol reactivity and recovery. Simple slope tests revealed that reappraisal moderated the association between suppression and both phases of cortisol responsivity.

Conclusion: Our results suggest that reappraisal represents a protective factor against the deleterious effects of suppression on stress responsivity. This study underlines the importance of investigating emotion regulation strategies as a means to understand individual differences in vulnerability to stress-related psychopathologies such as anxiety and depression.     

Capability as Opportunity: How Amartya Sen Revises Equal Opportunity

Although the concept of equal opportunity has received scant attention from theological ethics, it attracts widespread approval in the U.S. popular culture and has been examined extensively by contemporary moral philosophy. Amartya Sen's conception of capabilities as "freedom" or "real opportunity" corrects deficiencies in both popular and philosophical conceptions of equal opportunity that ignore interpersonal variations in mental, physical, and psychological abilities beyond agents' control. Recent theologically informed conceptions of love and common grace affirm and revise Sen's conception of equal capability as equal opportunity. The resulting understanding of equal opportunity is quite different from some uses of this concept and could be an important criterion for a just society.
