Is there an alternative cerebral network associated with enhanced phonological processing in deaf speech-users? An exceptional case

Most people born deaf and exposed to oral language show scant evidence of sensitivity to the phonology of speech when processing written language. In this respect they differ from hearing people. However, occasionally, a prelingually deaf person can achieve good processing of written language in terms of phonological sensitivity and awareness, and in this respect appears exceptional. We report the pattern of event-related fMRI activation in such a deaf reader while performing a rhyme-judgment on written words with similar spelling endings that do not provide rhyme clues. The left inferior frontal gyrus pars opercularis and the left inferior parietal lobe showed greater activation for this task than for a letter-string identity matching task. This participant was special in this regard, showing significantly greater activation in these regions than a group of hearing participants with a similar level of phonological and reading skill. In addition, SR showed activation in the left mid-fusiform gyrus; a region which did not show task-specific activation in the other respondents. The pattern of activation in this exceptional deaf reader was also unique compared with three deaf readers who showed limited phonological processing. We discuss the possibility that this pattern of activation may be critical in relation to phonological decoding of the written word in good deaf readers whose phonological reading skills are indistinguishable from those of hearing readers.     

Empathizing, systemizing and finger length ratio in a Swedish sample

von Horn, A., Bäckman, L., Davidsson, T. & Hansen, S. (2010). Empathizing, systemizing and finger length ratio in a Swedish sample. Scandinavian Journal of Psychology, 51, 31–37.
The Empathy- and Systemizing Quotients (EQ and SQ, respectively; Baron-Cohen, 2003 ) were determined in a Swedish sample consisting mainly of university undergraduates. Females had significantly higher EQ than males, who in turn scored higher on the SQ inventory. Gender explained 12–14% of the variation. Males were strikingly overrepresented in the group defined by a high SQ/low EQ profile or by a large SQ – EQ difference; females dominated among people with a low SQ/high EQ profile or by a large EQ – SQ difference. Students majoring in the natural sciences had higher SQs than psychology majors, but in both groups the gender difference in SQ and EQ was strong. For each participant a weighted composite score was generated by multivariate processing of the EQ and SQ data (Partial Least Square Discriminant Analysis). These scores were associated in a sex-linked fashion to a biometric measure reflecting prenatal testosterone exposure, i.e. the ratio between index (2D)- and ring (4D) finger lengths. In males a high (female-typical) 2D:4D ratio predicted an enhanced tendency to empathize and a reduced tendency to systemize; in women, by contrast, the 2D:4D ratio was unrelated to these traits. The present research confirms earlier work of a gender difference in EQ and SQ. The difference appears robust as it appears as large in Sweden (a country with high cultural gender-equality) as in countries with considerably lower gender-equality.     

BREACH AND FULFILLMENT OF THE PSYCHOLOGICAL CONTRACT: A COMPARISON OF TRADITIONAL AND EXPANDED VIEWS

Breach and fulfillment in a psychological contract has traditionally been studied with approaches that are conceptually and methodologically limited. We compared predictions derived from the traditional view to predictions from an expanded view that maintains the distinction between promised and delivered inducements and examines their joint relationship with employee satisfaction. The traditional and expanded views were compared using longitudinal data and polynomial regression analysis. Results provided little support for the traditional view. In contrast, results supported the expanded view and revealed that relationships for breach and fulfillment are more complex than previously suggested. Specifically, satisfaction depended on whether breach represented deficient or excess inducements and the particular inducement under consideration. Moreover, satisfaction was more strongly related to delivered inducements than promised inducements. These results question basic tenets of psychological contract research and indicate new avenues for research that build on the expanded view developed in this article.     

A Model of the Perceived Competence of Conflict Strategies

This study examines how strategic communication is linked to specific relational features. We hypothesize that perceptions of a communicator's competence mediate the effects of conflict strategies on the relational outcomes measured by trust, control mutuality, intimacy, and satisfaction. The components of competence were specific and general appropriateness, effectiveness, and global competence; these were included in LISREL analyses to investigate How the variables conflict, competence, and relational outcomes were linked. Participants reported on their partners’ conflict strategies, their own perceptions of the partner's competence, and relational variables. The results reveal that integrative strategies were positively linked to competence, whereas distributive and avoidant strategies were negatively linked to competence. The results support the view that competence perceptions mediate the link between conflict messages and relational outcomes.     

Physiological Desensitization and Judgments About Female Victims of Violence

Earlier published studies have indicated that exposure to filmed violence against women leads to decreased perceptions of violence, systematic reductions in emotional reactions, reduction in self-reported physiological arousal to the violence in the films, and a tendency for subjects exposed to the violence to judge a victim of a sexual assault presented in a more realistic context more harshly. The present study was designed to measure physiological desensitizatian (heart rate) and to investigate the relationships between this measure and other cognitive, affective, and attitudinal components of the desensitization process. Subjects were either exposed to a two-hour videotape portraying violence against women or to exciting, nonviolent material (i.e., auto races, nonviolent sex). Following this, all subjects were exposed to two brief clips of violence perpetrated by a man against a women. During these clips, all subjects’ heart rates were monitored. Afterwards mood reactions and perceptions of the perpetrators and victims depicted in the dependent measure clips were measured. The results indicated that heart rates for subjects exposed to the violent videotape were lower during the final 90 seconds of each violent dependent measure film clip than controls. Although the violence-viewing subjects experienced no change in moods, control subjects experienced significant increases in hostility, anxiety, and depression during the dependent measure clips. Subjects in the violence-viewing condition attributed less injury to the victims but greater responsibility to the perpetrators in the dependent measure clips, compared to control subjects. There was no apparent relationship between physiological desensitization and later victim/perpetrator judgments.     

The Impact of Social Issue Television Programming on Attitudes Toward Rape

A field experiment was conducted to evaluate the impact of a television movie about acquaintance rape on subsequent attitudes about rape. To maximize external validity, a nationally representative sample of 1,038 male and female adults from three age groups was selected to participate in the study. These participants were then randomly assigned to view or not view the movie over a closed-circuit channel, prior to the network broadcast of the film. Afterward, acceptance of rape myths and perceptions of rape as a social problem were measured. The movie increased awareness of date rape as a social problem across all demographic groups. The movie also had a prosocial effect on older females who were less likely to attribute blame to women in date rape situations after exposure. However, the opposite effect tended to occur among older men. The findings suggest that emotional involvement with a movie and selective perception of movie events may mediate the impact of social issue television programming.
