Interhemispheric communication involving multiple tasks: A study of children with dyslexia

The study investigated whether inefficient interhemispheric communication is involved in developmental dyslexia using multiple tasks. A finger localization task, rhyming judgment task, primed lexical decision task, and a visual half-field presentation paradigm were used. Nineteen dyslexic children (mean age = 13.1 years) were compared with 26 chronological age-matched normal children. Although the dyslexic group demonstrated significantly slower and less accurate performance in all three tasks, there was no significant group difference in term of interhemispheric communication. However, priming effects demonstrated by the dyslexic group (p < .05) further indicate that their reading problems may stem from the word retrieval process from the long term memory.     

Comparing judgments of stuttering made by students, clinicians, and highly experienced judges

Purpose: The purpose of this study was to compare judgments of stuttering made by students and clinicians with previously available judgments made by highly experienced judges in stuttering. Method: On two occasions, 41 university students and 31 speech-language pathologists judged the presence or absence of stuttering in each of 216 audiovisually recorded 5-s intervals of the speech of adults who stutter. Intrajudge and interjudge agreement were calculated, and comparisons were made to judgments previously made about the same recordings by 10 highly experienced judges of stuttering. Results: Students and clinicians showed similar and relatively high levels of intrajudge and interjudge agreement, but both students and clinicians identified less than half as much stuttering as the highly experienced judges had identified. Conclusions: These results replicate previous findings of high agreement coexisting with low accuracy in students’ judgments of stuttering, extending those findings to show that similar problems are evident in judgments made by practicing clinicians. Implications include the need for explicit stuttering judgment training programs for both students and practicing clinicians.

Educational objectives: After reading this article, the reader will be able to: (1) describe different methods for identifying stuttering and possible problems associated with each method; (2) describe two different methods for reporting interjudge reliability; (3) describe how the identification of stuttering differs for student, clinician, and highly experienced judges.     

Response of female cuttlefish Sepia officinalis (Cephalopoda) to mirrors and conspecifics: evidence for signaling in female cuttlefish

Cuttlefish have a large repertoire of body patterns that are used for camouflage and interspecific signaling. Intraspecific signaling by male cuttlefish has been well documented but studies on signaling by females are lacking. We found that females displayed a newly described body pattern termed Splotch toward their mirror image and female conspecifics, but not to males, prey or inanimate objects. Female cuttlefish may use the Splotch body pattern as an intraspecific signal, possibly to reduce agonistic interactions. The ability of females to produce a consistent body pattern in response to conspecifics and mirrors suggests that they can recognize same-sex conspecifics using visual cues, despite the lack of sexual dimorphism visible to human observers.

Perceived stress and physiological dysregulation in older adults

We use a population-based representative sample of older Taiwanese to investigate links between respondents' perceived levels of stress and a broad set of biological measures. These biomarkers were collected at a single time (2000) and reflect sympathetic nervous system (SNS)-activity, hypothalamo-pituitary-adrenal (HPA)-activity, immune function, cardiovascular function, and metabolic pathways. We model the relationship between perceived stress and (1) extreme values for each of 16 individual biological indicators; and (2) a measure of cumulative physiological dysregulation based on the full set of biomarkers. We consider two measures of perceived stress, one derived from the 2000 interview and the second based on data from three interviews (1996-2000). Age and sex-adjusted models reveal significant associations between measures of perceived stress and extreme values of cortisol, triglycerides, interleukin-6 (IL-6), dehydroepiandrosterone sulphate (DHEAS) and fasting glucose. Examined individually, numerous biomarkers, including those pertaining to blood pressure and obesity, are not significantly related to perceived stress. Jointly, however, the measure of cumulative physiological dysregulation is associated with both the level of perceived stress at a given time and to a longitudinal measure of perceived stress. Some results suggest that the relationship between level of perceived stress and physiological response is stronger for women than men.     

Cuttlefish (Sepia officinalis: Cephalopoda) hunting behavior and associative learning

Because most learning studies in cephalopods have been performed on octopods, it remains unclear whether such abilities are specific to octopus, or whether they correlate with having a larger and more centrally organized brain. To investigate associative learning in a different cephalopod, six sexually mature cuttlefish (Sepia officinalis) participated in a counterbalanced, within-subjects, appetitive, classical conditioning procedure. Two plastic spheres (conditioned stimuli, CSs), differing in brightness, were presented sequentially. Presentation of the CS+ was followed 5 s later by a live feeder fish (unconditioned stimulus, US). Cuttlefish began to attack the CS+ with the same type of food-acquisition seizures used to capture the feeder fish. After seven blocks of training (42 presentations of each CS) the difference in seizure probability between CS+ and CS– trials more than doubled; and was found to be significantly higher in late versus early blocks. These results indicate that cuttlefish exhibit autoshaping under some conditions. The possible ecological significance of this type of learning is briefly discussed.Electronic Supplementary Material Supplementary material is available for this article at     

Solidarity across group lines: Secondary transfer effect of intergroup contact,perceived moral distance,and collective action

We tested, in three studies, whether the generalization of contact effects from primary to secondary outgroups—the secondary transfer effect (STE)—occurs for collective action. The results supported a serial mediation model: contact with immigrants by advantaged group members (Italians: Study 1, N = 146, 121 females, M_age = 28.31 years; Study 3, N = 406, 239 females, M_age = 36.35; British people, Study 2, N = 160, 113 females, M_age = 32.31) was associated with lower perceived moral distance toward primary outgroups, which in turn was associated with more positive attitudes and greater collective action intentions toward primary outgroups, and lower perceived moral distance toward secondary outgroups. Lower perceived moral distance toward secondary outgroups and stronger collective action intentions toward the primary outgroup were associated with higher collective action intentions toward secondary outgroups (results were inconsistent for attitudes). We discuss the findings with a focus on how a consideration of perceived moral distance extends current theorizing, and the relevance of generalized prejudice for the STE.

Positive Illusions and Coping with Adversity

ABSTRACT We review the literature showing that positive illusions (i.e., self-aggrandizement, unrealistic optimism, and exaggerated perceptions of control) are common and associated with successful adjustment to stressful events, including conditions of extreme adversity. Using theory and recent data, we offer a basis for integrating positive illusions with the constraints of reality. We explicitly contrast the social psychological model of positive illusions with a personality viewpoint that addresses the question “Do higher levels of positive illusions predict higher levels of adjustment?” These issues are explored in the context of people coping with an array of normal stressful events, as well as those coping with more extreme stressful events, including cancer, heart disease, and HIV infection. Life is seldom as unendurable as, to judge by the facts, it ought to be. —Brooks Atkinson

Negative Threat Appeals and Earthquake Preparedness: A Person-Relative-to-Event (PrE) Model of Coping With Threat1

Individual preparation, or the lack thereof, for the occurrences of external events that threaten the well-being of individuals is an issue of worldwide concern. The present studies were designed to investigate the impact of a particular type of persuasive communication (i.e., fear-arousing or negative threat appeals) on preparedness behavior regarding the possible occurrence of a damaging earthquake. A general model of coping, the person-relative-to-event (PrE) model, emphasizing the relationship between level of appraised threat and person resources, was applied to this issue. It was predicted that negative threat appeals using combinations of levels of factors that cause a person to appraise their resources as sufficient in quantity and quality to obviate or minimize the negative consequences of a threatening earthquake would increase levels of earthquake preparedness to a greater extent than would communications that do not. Results of Study I were partially supportive of these predictions. In Study 2, patterns of changes in preparedness behavior fit predictions generated by the PrE model to a greater extent when felt responsibility for preparing for the occurrence of an earthquake was high than when it was low. Implications of the research and theory underlying this investigation are discussed.     

Counselling children and adults about AIDS/HIV: The ripple effect on haemophilia care settings

Haemophilia and HIV/AIDS are life-long, life-threatening conditions for which there is treatment but no cure. Both affect not only the patient but all members of the family. This paper focusses on how the counselling of those with AIDS/HIV has been affected by dilemmas such as treatment, infectious aspects, blood donation, sex, the media and having children. The impact of haemophilia and AIDS on the family and the ripple effect on health care staff is addressed.
