Recovery and predictors of language skills two years following pediatric traumatic brain injury

Subtle language processing difficulties may adversely affect scholastic performance, as well as communication and social skills. It is therefore crucial that language skills are monitored following traumatic brain injury (TBI) in childhood. The present study examined language skills in a group of 68 children who had sustained a mild, moderate or severe TBI. Results indicated that during the acute stage a dose-response relationship was evident, where severe TBI was associated with poorest performance and mild TBI with least deficits. By 24 months post-TBI, it was clear that for some language functions, the severe TBI group showed substantial recovery, and at times performed better than the moderate TBI group. Predictors of language and literacy skills at 24 months post TBI included pre-injury communication skills, socio-economic status, age at injury, and Vocabulary, as measured by the Wechsler Intelligence Scale for Children (WISC-111).     

Does Belief Have an Aim?

The hypothesis that belief aims at the truth has been used to explain three features of belief: (1) the fact that correct beliefs are true beliefs, (2) the fact that rational beliefs are supported by the evidence and (3) the fact that we cannot form beliefs `at will. I argue that the truth-aim hypothesis cannot explain any of these facts. In this respect believing differs from guessing since the hypothesis that guessing aims at the truth can explain the three analogous features of guessing. I conclude that, unlike guessing, believing is not purposive in any interesting sense.     

TRAINING AND GENERALIZATION OF SEXUAL ABUSE PREVENTION SKILLS FOR WOMEN WITH MENTAL RETARDATION

Previous research has shown that behavioral skills training to teach sexual abuse prevention skills to women with mental retardation results in skill acquisition but poor generalization. In this investigation we evaluated procedures for enhancing generalization following training. Five women with mental retardation received 10 behavioral skills training sessions followed by in situ training when the skills did not fully generalize. Behavioral skills training resulted in skill acquisition and in situ training produced generalized responding during naturalistic assessments.     

Ambiguity seeking in multi-attribute decisions: Effects of optimism and message framing

This paper investigates the influence of message framing and personality variables on preferences over ambiguity in the context of multi-attribute decision scenarios. Undergraduate subjects responded to scenarios in which one of two medical treatments was associated with ambiguous probabilities of treatment effects. Probabilities were either positively or negatively framed. Subjects indicated their degree of preference for one treatment over the other. Subjects' optimism, trait anxiety, health locus of control, need for cognitive structure, and current mood were measured. In two separate studies, subjects preferred ambiguity when probabilities were positively framed, and were neutral toward ambiguity when probabilities were negatively framed. Also, in both studies the preference for ambiguity in positively framed scenarios was greater for more optimistic subjects. The unexpected finding of ambiguity seeking may be associated with the use of different decision strategies in multi-attribute versus single-attribute decisions.     

Perceived social structure,role, and communication patterns in an organization

Relationships among organizational roles, perceptions of the structure of the organization, and communications were studied in a university psychology department. Fifty-five members, representing five status groups (e.g., faculty, graduate students, etc.) and four sections of the department (e.g., Counseling, Experimental, etc.), judged the similarity of 16 faculty stimuli, rated the faculty on their interests and activities, and reported on their own communications. Individual Differences Multidimensional Scaling analysis of the similarities data revealed four dimensions of the perceptions of the organization: Section Affiliation, Teaching versus Research, Interest in Industrial Psychology, and Orthodoxy of Life-Style. Section groups differed significantly both in their communications and in the way the Orthodoxy of Life-Style dimension was weighted in their perceptions of the organization. Perceptions of the organization were related to communication behavior.     

Two Important Distinctions in Social Support: Kind of Support and Perceived Versus Received1

The present study was conducted to examine the effects of social support on adjustment to a first cardiac event. There were two goals: (a) to determine which function of support best facilitated adjustment and (b) to determine whether perceived or received support had a greater impact on psychological health. Sixty-four patients and their spouses were interviewed shortly before hospital discharge and 3 months following discharge. The results indicated that perceived support has a greater impact on adjustment than received support and that received support does not necessarily indicate that needs are being met. The most helpful form of support was best understood by considering the stressor phase, patient and spouse needs, and the adjustment outcome. Consistent with previous research, however, the negative aspects of social relationships were more robust predictors of well-being than the positive aspects of social relationships.     

Judgments of men's and women's feelings during hypothetical social interactions

We studied college students' perceptions of how good/bad and how powerful/powerless men and women feel during hypothetical social interactions. Stimuli were constructed by combining each of 16 behaviors that fell into four categories (negative, low power, sexual, and help) with each of four dyads (male-male, male-female, female-male, female-female). Subjects made judgments about the likelihood of each behavior occurring, and about how actors and recipients felt when engaging in each of 16 behaviors. Three themes pervaded the results. First, subjects perceived men to feel more powerful than women whether behaving as actors or recipients—especially during interactions with women. Second, subjects perceived behaviors to be more likely, and actors and recipients to feel better and more powerful when the interaction pattern was consistent with gender role norms. Third, subjects perceived recipients' affective responses as being more polarized in opposite-sex than in same-sex dyads. Results from this research show that subjects' perceptions about feelings are largely consistent with the literature on social interaction and sex role stereotypes, and are similar for male and female subjects. In addition, our results provide a rich set of hypotheses concerning whether perceptions of feelings reflect actual feelings and are related to interaction participants' actual behavior.     

Gender-Role Cognition in Three-Year-Old Boys and Girls

Although the multidimensionality of gender roles has been well established, few researchers have investigated male and female roles separately. Because of the substantial differences in the ways male and female roles are portrayed in our culture, boys and girls may think and learn about these roles differently. The male role is more clearly defined, more highly valued, and more salient than the female role; thus, children's cognitions about these two roles may be expected to differ. The present study addressed the question of whether there is sex-typical variation in gender labeling, gender-role knowledge, and schematicity. Participants were 120 families; 15% were from minority ethnic groups, and 17% were single-parent families; 25% of the parents had a high school education or less. Results indicated that at 36 months of age, boys were less able to label gender and less knowledgeable about gender roles than were girls. Boys' knew more about male stereotypes than female stereotypes, whereas girls knew considerably more than boys about the female role and as much as boys about the male role. Boys and girls were found to be similar in gender schematicity. Traditionality of parental attitudes regarding child-rearing and maternal employment were not strongly related to children's gender cognition.     

Differential effects of the menstrual cycle on reactive and proactive aggression in borderline personality disorder

Borderline personality disorder (BPD) is characterized by rapidly shifting symptoms, including intense anger and aggressive behavior. Understanding how fluctuations in ovarian hormones across the menstrual cycle may contribute to symptom instability is key for accurate assessment of BPD symptoms and effective interventions. Reactive and proactive aggression, as well as anger-in and anger-out, were assessed daily in 15 physically healthy, unmedicated naturally cycling female individuals meeting criteria for BPD across 35 days. Urine luteinizing hormone surge and salivary progesterone were used to confirm ovulation and verify the cycle phase. Multilevel models evaluated cyclical differences of symptoms between cycle phases. Both forms of aggressive behavior demonstrated marked cycle effects, with reactive aggression highest during the midluteal cycle phase, co-occurring with initial increases in anger and irritability and followed by perimenstrual peaks in anger and anger-in. In contrast, highest levels of proactive aggression were observed during the follicular and ovulatory phases, when emotional symptoms and anger were otherwise at lowest levels. These findings highlight the importance of identifying the function of aggression when considering potential psychological and biological influences. Naturally cycling individuals with BPD may be at elevated risk for luteal worsening of a range of interpersonally reactive symptoms, including reactive aggression, whereas proactive aggression may occur more in phases characterized by less emotional and cognitive vulnerability and greater reward sensitivity. Research on aggression in this population should consider cycle effects. Cycling individuals with BPD attempting to reduce aggressive behavior may benefit from cycle-tracking to increase awareness of these effects and to develop appropriate strategies.     

Evaluating the independence of sex and expression in judgments of faces

Face recognition models suggest independent processing for functionally different types of information, such as identity, expression, sex, and facial speech. Interference between sex and expression information was tested using both a rating study and Garner's selective attention paradigm using speeded sex and expression decisions. When participants were asked to assess the masculinity of male and female angry and surprised faces, they found surprised faces to be more feminine than angry ones (Experiment 1). However, in a speeded-classification situation in the laboratory in which the sex decision was either "easy" relative to the expression decision (Experiment 2) or of more equivalent difficulty (Experiment 3), it was possible for participants to attend selectively to either dimension without interference from the other. Qualified support is offered for independent processing routes.
