Does DSM-IV Asperger's Disorder Exist?

DSM-IV criteria for autistic and Asperger's disorders were applied to 157 children with clinical diagnoses of autism or Asperger's disorder. All children met the DSM-IV criteria for autistic disorder and none met criteria for Asperger's disorder, including those with normal intelligence and absence of early speech delay. The reason for this was that all children had social impairment and restricted and repetitive behavior and interests (required DSM-IV symptoms for both autistic and Asperger's disorders) and all had a DSM-IV communication impairment (which then qualified them for a diagnosis of autistic disorder and not Asperger's disorder). Communication problems exhibited by all children were impaired conversational speech or repetitive, stereotyped, or idiosyncratic speech (or both), which are DSM-IV criteria for autism. These findings are consistent with those of 5 other studies and indicate that a DSM-IV diagnosis of Asperger's disorder is unlikely or impossible.     

Family Therapy with Unmarried African American Mothers and Their Adolescents

Almost two-thirds of African American births are to unmarried mothers, and these single parents are among the most economically vulnerable in the United States. The effects of chronic stressors such as poverty can compromise the ability of these mothers to parent effectively, particularly during the developmental period of adolescence, typically a stressful phase of parenting. This article describes a multidimensional family therapy (MDFT) approach to working with African American adolescents who have drug and/or behavior problems. It is maintained that addressing the intrapersonal functioning of African American single mothers is vital if they are to re-establish the attachment bonds necessary for the maintenance of essential parental influence in the lives of their adolescents. Through systematic attention to the parent as an individual, leading to a balance between self-care and care for others, parental supervision is more easily achieved and relational impasses between parent and adolescent more equitably resolved.     

Differences in semantic and translation priming across languages: The role of language direction and language dominance

In the present study, we examined bilingual memory organization, using the priming paradigm. Many of the previous studies in which this experimental technique has been used in the bilingual domain appear to have had several differences in methodology that have caused there to be a lot of variation in the data reported. The aim of the present work was to create an experimental situation that was well constrained so that automatic processes could be observed. In Experiment 1, Spanish-English bilinguals participated in an unmasked semantic- and translation-priming study in which a lexical decision task was used. The results revealed significant translation-priming effects in both language directions and, unexpectedly, significant semantic priming in the L2-L1 direction only. In Experiment 2, we examined semantic- and translation-priming effects with a forward mask design. The results indicated that significant priming was obtained only for translation word pairs in both language directions. These results are discussed with regard to current models of bilingual memory representation.     

Is there an internal association of numbers to hands? The task set influences the nature of the SNARC effect

The SNARC effect refers to the association of smaller numbers with the left and of larger numbers with the right side of extracorporal space (Dehaene, Bossini, & Giraux, 1993). We tested the assumption that, in addition to these associations, numbers are also related to participants' hands. We report two experiments with vertically arranged buttons in which the nature of the SNARC effect depended on whether the task set was button or hand related: In the first case, a vertical location-related SNARC effect occurred, whereas in the second a hand-related SNARC effect was found. Our third experiment confirmed that space-related number representations dominate the SNARC effect when the buttons are arranged horizontally. We concluded that both effector- and space-related number representations can influence and modify the SNARC effect.     

Pigeons discriminate continuous versus discontinuous line segments

Three experiments examined various facets of the perception of continuous and discontinuous line segments in pigeons. Pigeons were presented with 2 straight lines that were interrupted by a gap. In some instances, the lines were the same angle and were positioned so that they appeared (to human observers) to form a continuous line. In other instances, the lines were different angles or the same angle but spatially misaligned. The birds were trained to classify each stimulus as continuous or discontinuous using a go/no-go procedure. A series of tests followed in which the birds received novel discontinuous displays made up of familiar line segments, continuous and discontinuous stimuli made up of novel line segments (novel straight lines or curved lines), and familiar displays in which the gap was covered with a gray square. Results from the tests indicated that 2 of the 3 pigeons had learned a continuous-discontinuous categorization and that they appeared to use the relationship between the 2 line segments in discriminating the displays.     

Coping styles and personality: a biometric analysis

Previous research suggests that coping styles are modestly heritable and that this genetic influence is shared in large part with genetic influences on personality. To test this hypothesis, we estimated the heritable basis of the Coping Inventory for Stressful Situations in a sample of 91 monozygotic and 80 dizygotic twin pairs. Task-oriented, emotion-oriented, and social diversion coping styles were modestly heritable (h(2)=.17 to .20), whereas the use of distraction appeared to be influenced solely by environmental factors. Multivariate analyses showed that genetic contributions to coping styles were, at best, only modestly related to genetic contributions to personality (r=-.03 to .35). Environmental contributions to personality were unrelated to environmental factors in coping style. These results suggest that coping style is not merely a manifestation of basic personality traits but does support the possibility that the genetic factors in personality influences have a modest influence on an individual's preferred coping style or strength (e.g., rigidity vs flexibility).     

Prolonged exposure therapy for chronic combat-related PTSD: a case report of five veterans

Prolonged exposure (PE) therapy has been found efficient in reducing posttraumatic stress disorder (PTSD) symptoms mostly among rape victims, but has not been explored in combat-related PTSD. Five patients with severe chronic PTSD, unresponsive to previous treatment (medication and supportive therapy) are described. Patients were evaluated with the PTSD Symptom Scale-Interview, and Beck Depression Inventory, before and after 10-15 sessions of PE therapy. All five patients showed marked improvement with PE, with a mean decrease of 48% in PTSD Symptom Scale-Interview score and 69% in Beck Depression Inventory score. Moreover, four patients maintained treatment gains or kept improving 6-18 months after the treatment. The results suggest that PE was effective in reducing combat-related chronic PTSD symptoms.     

Methodological considerations in performing semantic- and translation-priming experiments across languages

Research in the field of bilingualism has had as its principal aim to describe the structure and function of memory for bilingual speakers. A primary technique that has been used to examine bilingual memory is an examination of cross-language word priming (semantic and translation), using the lexical decision and pronunciation tasks. Although studies have, on occasion, revealed greater degrees of word priming from a dominant to a subordinate language, in comparison with the reverse, a careful review of the methodology that has been used reveals a number of issues that render conclusions such as this quite problematic. Parameters of concern include language proficiency, cognate status, masking, control conditions, word frequency and length, stimulus onset asynchrony, relatedness proportion, and nonword ratio. These factors are discussed, as well as recommendations for conducting future empirical research in this area of investigation.     

Perceptions and metaperceptions of same-sex social interactions in college women with disordered eating patterns

This study compared perceptions and metaperceptions after a social interaction between a woman with disordered eating (subclinical bulimia nervosa) and a female interaction partner. Hypotheses were: women with disordered eating would have more negative metaperceptions of social interactions than women without disordered eating, and women with disordered eating would show a greater discrepancy between metaperceptions and perceptions than women without disordered eating. All participants completed questionnaires about their perceptions and metaperceptions post-interaction. Results showed women with disordered eating thought that they had made a negative impression; findings addressing the relationships among social desirability, loneliness, social support utilization, and fear of negative evaluation are also discussed.
