Concurrent Verbal and Emotion Laterality Effects Exhibited by Normally Achieving and Learning Disabled Children

This study assessed both left- and right-hemisphere functions simultaneously when two-syllable words differing only in the initial stop consonant and spoken in different emotional tones were paired dichotically. Seventy-two right-handed normally achieving children, 12 boys and 12 girls at each of grades 1, 3, and 5, were instructed to detect either the presence of a specific word or of a specific emotion. In addition, 30 right-handed learning disabled (LD) children (age-matched to the normal controls) were assessed to determine whether LD children distribute verbal and nonverbal functions to different hemispheres. Results indicated that although both control and LD children demonstrated an overall REA for word stimuli and an LEA for emotional stimuli, and that emotional stimuli were easier to process than word stimuli, LD children were less accurate in processing both types of stimuli than their control counterparts. ‘Complementary specialization,’ as assessed through distribution of laterality effects, was found to be greater for control children than for LD children. However, the lack of consistency in complementary specialization found among the three developmental grade levels may be indicative that independent brain mechanisms underlying verbal and emotional processing have yet to be fully established in children. Further, in contrast to adult findings, a larger LEA was obtained for the emotion ‘happy’ than for the emotion ‘sad.’ It was concluded that whereas independent hemisphere processing for words and emotions is somewhat prevalent for control children, LD children might not be as strongly lateralized for opposite hemisphere processing of these functions.     

Patterns of Memory Performance in Children with Controlled Epilepsy on the CVLT-C

Decreased memory skills have been reported in children with epilepsy. However, standardized instruments to evaluate learning and memory in children have been unavailable until recently. The present study was designed to assess memory patterns in children with epilepsy based on the California Verbal Learning Test-Children's Version (CVLT-C). The test was administered to 44 children with complex partial seizures and 21 children with generalized seizures between 8 and 13 years of age. Children in the study had been treated for epilepsy for at least 6 months, had well-controlled seizures on monotherapy, and had no evidence of anticonvulsant toxicity. Children with head injuries, learning disabilities, or hyperactivity were excluded. Test results did not reflect differences in memory performance based on seizure type. Scores for the entire sample indicated intact new learning, decreased intrusions and perseverative responses, and better short-term than long-term delayed recall. Recognition skills were stronger than long-term delayed recall skills and suggested that memory performance may be improved for these children when a multiple-choice format is available in academic settings.     

The role of perfectionism in cognitive behaviour therapy outcomes for clinically anxious children

The main aim of this study was to determine whether pre-treatment levels of child perfectionism impacted on anxiety treatment outcomes for school-aged children. In addition, it was investigated whether child perfectionism decreased following treatment for anxiety. Participants were sixty-seven clinically anxious children aged 6–13 years (female = 34; majority Caucasian) who were enrolled in a group-based cognitive behaviour therapy program, and their parents. They completed self-report questionnaires on anxiety and depressive symptoms and were administered a diagnostic interview to determine the type and clinician rated severity of anxiety and related disorders pre- and post-treatment and at 6-month follow-up. Self- and parent-rated perfectionism were also measured pre-treatment, while a subset of children completed perfectionism measures post-treatment as well. Self-Oriented Perfectionism, but not Socially Prescribed Perfectionism, predicted poorer self-reported treatment outcome (higher levels of anxiety symptoms) immediately following treatment and at 6-month follow-up when using a multi-informant approach. Additionally, both Self-Oriented and Socially Prescribed child perfectionism significantly reduced immediately following treatment. Despite reductions in child perfectionism following anxiety treatment, higher Self-Oriented Perfectionism may impact negatively on child anxiety treatment outcome.     

French Philosophy Over the Last Decade

The controversy between Popper and Adorno at the conference held by the German Sociological Association at Tübingen in 1961, brought into focus issues that had been simmering for some years, and which were to go far beyond methodological dispute, into the foundational question of the relation between theory and society. The concept of totality and its concomitant totalitarian moral implications provide the initial focus, and it is argued that the apparent incommensurability of the two attitudes towards this concept derives not merely from substantive theoretical differences, but from distinct modes of theorizing through language. This in turn, has implications for the understanding of their respective constructions of, and relations to, reality. A comparative analysis of statements made by both men reveals the essentially monologic nature of one orientation.     

Two-and-a-Half-Year-Olds’ Memory for Sources of Actions: Contextual Support Facilitates Recall

This research examines the early emergence of source-monitoring abilities. Previous research has consistently demonstrated that children as young as 3 to 4 years of age do well on simple versions of action-based source-monitoring tasks. Research on even younger children, however, remains lacking. In this study we examined whether 2½-year-olds could accurately recall source on a simplified task. For the procedure, we used an action-based task in which children collaborate with an experimenter to build a model farm. During construction, the child and the experimenter took turns placing items on the farm. After construction, children were administered a source memory test in which they were asked to recall who had placed each item. To more closely examine factors that influence source accuracy in this young population, we included two conditions that varied in terms of contextual support. In the no-context-cues condition, in line with typical source-monitoring tasks, children were asked the source test question while items were presented individually and the farm was not in view. In the context-cues condition, the original spatial array of farm items was left intact to provide additional cues for children's source decisions. The main finding was that children in both conditions showed high levels of source accuracy at test indicating a surprisingly early age of emergence for this ability. Also, as predicted, children in the context-cues condition were the most accurate in attributing source.     

Sources of politico-economic attitudes: students’ introspections

Our aim is to shed more light on university students’ sources of attitudes towards the market economy, social inequality, and the responsibilities of the state. Analyzing survey data of almost 500 students at a German university, we identify those sources the subjects report to be important in the process of forming their politico-economic attitudes. We explore the differences between our sample of local students and the German General Social Survey, as well as the characteristics of subjects expressing no opinion. We also examine whether the sources which were reported to be important significantly contribute to the prediction of conservative political attitudes, concentrating specifically on the attitude effects of economic education.     

Positive and negative affect,depression, and cognitive processes in the Cognition in the Study of Tamoxifen and Raloxifene (Co-STAR) Trial

ABSTRACT

Objectives: This study examined the relationship between positive and negative affect, depressive symptoms, and cognitive performance. Methods: The sample consisted of 1479 non-demented, postmenopausal women (mean age = 67 years) at increased risk of breast cancer enrolled in the National Surgical Adjuvant Breast and Bowel Project’s Study of Tamoxifen and Raloxifene. At each annual visit, women completed a standardized neuropsychological battery and self-report measures of affect and depression. Data from three visits were used in linear mixed models for repeated measures using likelihood ratio tests. Separate analyses were performed to relate positive/negative affect and depression to each cognitive measure. Results: Higher positive affect was associated with better letter fluency (p = .006) and category fluency (p < .0001). Higher negative affect was associated with worse global cognitive function (p < .0001), verbal memory (CVLT List B; p = .002), and spatial ability (p < .0001). Depressive symptoms were negatively associated with verbal knowledge (p = .004), figural memory (p < .0001), and verbal memory (p’s ≤ .0001). Discussion: Findings are consistent with some prior research demonstrating a link between positive affect and increased verbal fluency and between depressive symptoms and decreased memory. The most novel finding shows that negative affect is related to decreased global cognition and visuospatial ability. Overall, this research in a large, longitudinal sample supports the notion that positive affect is related to increases and negative affect to decreases in performance on distinct cognitive measures.     

The place of words and numbers in psychiatric research

In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics. Relationships between these objects of study can in turn be explored in three different ways: 1/ by a hermeneutic process, 2/ using statistics, the most frequent method in psychiatric research today, 3/ using equations, i.e. using mathematical relationships that are formal and deterministic. The 3 ways of representing entities (with language, locally with mathematics or globally with mathematics) and the 3 ways of expressing the relationships between entities (using hermeneutics, statistics or equations) can be combined in a cross-tabulation, and nearly all nine combinations can be described using examples. A typology of this nature may be useful in assessing which epistemological perspectives are currently dominant in a constantly evolving field such as psychiatry, and which other perspectives still need to be developed. It also contributes to undermining the overly simplistic and counterproductive beliefs that accompany the assumption of a Manichean “quantitative/qualitative” dichotomy. Systematic examination of this set of typologies could be useful in indicating new directions for future research beyond the quantitative/qualitative divide.     

Perceived rationality,morality, and power of social choice as a function of interdependence structure and social value orientation

The present study examines how individuals with different social value orientations (i.e. prosocial, individualistic, and competitive) construe the rationality, morality, and power of choices in four distinct interdependence structures which systematically differ in the motives that could underlie the most prosocial or least aggressive choice: (a) altruism only, (b) altruism and cooperation, (c) altruism, cooperation, and individualism, and (d) altruism, cooperation, individualism, and competition. Results revealed that rationality ratings, and to a lesser degree morality and power ratings, increased most when the motives that could underlie a choice were part of the perceiver's social value orientation. Overall, the pattern of rationality ratings provided reasonable support for the Goal Prescribes Rationality Principle. Ratings of morality and power suggested a corresponding Goal Prescribes Morality/Power Principle (for prosocials and individualists), but revealed only mixed support for the Might Over Morality Hypothesis.
