Analyse der Intelligenzstruktur bei männlichen Gymnasiasten der Klassen 6–9 (Untersekunda—Oberprima)

Zusammenfassung Die vorliegende Arbeit untersuchte die Anwendbarkeit des Intelligenz-Struktur-Test (IST) von Amthauer auf die Diagnostik der Schulbegabung. Die in der Arbeit verwerteten Daten (IST, Four-Picture-Test von van Lennep und Schulnoten) wurden an 519 männlichen Gymnasiasten der Klassen 6–9 (Untersekunda bis Oberprima) erhoben. Zunächst wurde geprüft, ob sich die Hypothese Amthauers, die besagt, daß für die einzelnen Berufe optimale Intelligenzxtrukturen zu ermitteln sind, die sich in typischen IST-Profilverläufen zeigen, auch auf den Bereich der Schule und die dort angenommenen Spezialbegabungen für die einzelnen Fächer übertragen und dort verifizieren läßt. ES erwies sich (Extremgruppenvergleich und Faktorenanalyse), daß dies nicht mit der nötigen Sicherheit möglich ist. Die individuelle Vielfalt der Testergebnisse verwischt die Gruppenunterschiede. Es wurde der Versuch unternommen, eine theoretische Begründung dafür abzuleiten.Weiter wurde versucht, mittels zweckmäßiger Untertestauswahl undgewichtung eine Kurzform des IST zur treffsicheren und ökonomischeren Vorhersage des allgemeinen Schulerfolges zu entwickeln. Die Validitöt ließ sich nicht bedeutsam steigern, hingegen konnte die Testzeit auf die Hölfte reduziert werden. Die notwendigen Daten zur Anwendung Dieser Kurzbatterie Anwendung dieser Kurzbatterie wurden mitgeteilt.Es wurde gezeigt, daß sich größere Diskrepanzen zwischen realer und vorhergesagter Schulleistung (anhand der Kurzbatterie berechnet) in quantitativen Merkmalen des Four-Picture-Test von van Lennep widerspiegeln. Diese Differenzen sind nicht nur durch Unsicherheiten der Merkmalserfassung erklärbar.Schließlich wurde geprüft, ob sprachlich Begabte gegenüber mathemathisch-naturwissenschaftlich Begabten im IST-Gesamtergebnis benachteiligt sind. Es zeigte sich, daß dies nicht der Fall ist, daß hingegen der IST bezüglich seines Gesamtergebnisses eine engere Beziehung zu mathematisch-naturwissenschaftlichen Leistungen hat als zu sprachlichen.     

Spontaneous Imitation of Fundamental Frequency and Speech Rate by Nonstutterers and Stutterers

Speech can be described either in terms of acoustics, as a perceptual outcome, or as a motor event. Central to theories of speech perception and production is an attempt to describe how these aspects of speech are interrelated. The present experiment investigated how the nonstutterers' and stutterers' reproductions of acoustically presented interrogative sentences were influenced by experimental variations of intonation (sentence initial vs. sentence final) and speech rate (normal vs. time compressed). We studied the effects of these stimulus manipulations on the speech rate and fundamental frequency (F₀ ) of 10 adult German-speaking nonstutterers and seven stutterers. Experimental manipulations of intonation and speech rate significantly influenced the syllable duration and speech rate of both normal speakers and stutterers. The fundamental frequency of the subjects' responses were also significantly influenced by the intonation of the stimulus. But the stutterers' increase in F₀ for stressed syllables was generally less pronounced than that of nonstutterers. These results imply that (a) the subjects not only extract linguistic meaning from intonation but that they also store extragrammatical speech rate information, and (b) the speakers adopt these speech rate variations for their own productions. Generally, these results demonstrate that speech perception is not limited to extracting linguistically invariant information. The results show that speakers actively generate their own prosody and that this generative process is influenced by the prosodic structure of another speaker's antecedent speech. The implications of these results for theories of speech production are discussed.     

Distinctness of perceived three-dimensional form induced by modulated illumination: Effects of certain display and modulation conditions

The present study concerns the distinctness of the 3-D shape-induced on flat displays by spacemodulated illumination (“shape from shading”). The displays that we used varied in structure, hue contrast, lightness contrast, and in the number of reflectance edges present. The modulations of the illumination were a square-wave grating, a gradual modulation (a blurred grating), and an “O’Brien modulation,” which combines an edge and a gradient. The displays were compared, using the paired comparison method, as to the distinctness of the perceived 3-D form. The results showed that the structure and chromatic color of the display were important factors facilitating the distinctness of the induced 3-D shape under all the modulation conditions. The results are discussed in relation to the “vector model” for color constancy, proposed in earlier papers.     

Preattentive bias for emotional information in panic disorder with agoraphobia.

A combined emotional Stroop and implicit memory (tachistoscopic identification) task with 3 types of words (panic-related, interpersonal threat, and neutral words) and 2 exposure conditions (subliminal, supraliminal) was administered to 35 patients with panic disorder and 35 age- and sex-matched controls. The patients showed Stroop interference for panic-related words both sub- and supraliminally and a similar but not equally robust effect on interpersonal threat words. On the tachistoscopic identification task, the patients identified more panic-related words than the controls did but showed no implicit memory bias effect. The patients' subliminal Stroop interference for panic-related words was found to correlate with trait anxiety and depression, although not with anxiety sensitivity.     

Validation of a motivation-based typology of angry aggression among antisocial youths in Norway

This article describes the validation of the Angry Aggression Scales (AAS), the Behavior Inhibition System and the Behavior Activation System (BIS/BAS) scales, the reactive aggression and proactive power scales in relation to a Norwegian sample of 101 antisocial youths with conduct problems (64 boys, 37 girls, mean age 15 ± 1.3 years) and 101 prosocial controls matched on age, gender, education, ethnicity, and school district. Maximum likelihood exploratory factor analyses with oblique rotation were performed on AAS, BIS/BAS, reactive aggression and proactive power scales as well as computation of Cronbach's alpha and McDonald's omega. Tests for normality and homogeneity of variance were acceptable. Factor analyses of AAS and the proactive/reactive aggression scales suggested a hierarchical structure comprising a single higher-order angry aggression (AA) factor and four and two lower-order factors, respectively. Moreover, results suggested one BIS factor and a single higher-order BAS factor with three lower-order factors related to drive, fun-seeking and reward responsiveness. To compare scores of antisocial youths with controls, t-tests on the mean scale scores were computed. Results confirmed that antisocial youths were different from controls on the above-mentioned scales. Consistent with the idea that anger is associated with approach motivation, AAS scores correlated with behavioral activation, but only explosive/reactive and vengeful/ruminative AA correlated with behavioral inhibition. Results generally validated the quadruple typology of aggression and violence proposed by Howard (2009).     

Eating-related problems among 13-15 year old Swedish adolescents: Frequency and stability over a one-year period

Viborg, N., Wångby‐Lundh, M., Lundh, L.‐G. & Johnsson P. (2012). Eating‐related problems among 13‐15 year old Swedish adolescents: Frequency and stability over a one‐year period. Scandinavian Journal of Psychology 53, 401–406. The frequency of eating‐related problems in young adolescents, and their stability over a one‐year period, was studied by the RiBED‐8 (Risk Behaviours related to Eating Disorders, 8 items) in a community sample of 13–15 year old adolescents who took part in a prospective study with a 2‐wave longitudinal design. The RiBED‐8 was found to have good reliability and construct validity among the girls, although it did not show equally convincing psychometric properties among boys. With a cut‐off of at least three critical answers on the RiBED‐8, 28.5–31.0% of the girls were seen as risk cases for the development of eating disorder. Of those girls who were risk cases at Time 1, a majority (68.8%) remained so at Time 2; of those girls who were not risk cases at Time 1, 16.1% became risk cases at Time 2. It is suggested that the RiBED‐8 is a brief, easily administered instrument that may be potentially useful in screening for eating‐related problems among girls.     

In-group ratings are affected by who asks and how: interactive effects of experimenter group-membership and response format

In three experiments, participants rated how well a number of adjectives described their in-group (e.g. kind-hearted, helpful, intelligent, efficient, etc.). In Experiment 1, females were found to rate their ingroup (females) more favorably when reporting verbally to female (rather than male) experimenters. This finding was further explored in two subsequent experiments where response format (written vs. verbal) was also manipulated. Both experiments revealed an interaction such that ethnic Swedes rated their in-group (Swedes) the most favorably when reporting verbally to an in-group experimenter and the least favorably when reporting verbally to a Middle Eastern experimenter. Results are discussed in relation to correction and contextual activation of social norms.     

Effects of two-year treatment with the cholinesterase inhibitor rivastigmine on behavioural symptoms in Alzheimer's disease

Alzheimer's disease (AD) is accompanied by prominent behavioural disturbances. They cause significant distress for both caregivers and patients and can play a major role in the decision to institutionalise AD patients. Recent evidence suggests that cholinergic deficiencies not only contribute to the memory and cognitive abnormalities of AD but are also responsible for some behavioural abnormalities seen over the course of the disease. In this study we assessed the ability of rivastigmine, a pseudo-irreversible cholinesterase inhibitor, to improve behavioural and psychopathologic symptoms in AD. The analysis included 34 patients present in the Germanarm of the international study B303 who received and completed long-term treatment with rivastigmine in the open-label study B305. Assessments of behaviour and psychopathological symptoms were performed using the behavioural component of the Clinicians Interview Based Impression of Change Plus (CIBIC-Plus). Results show that long-term treatment with rivastigmine can slow the progression of behavioural and psychopathological symptoms of AD. Behavioural symptoms showing stabilisation included aggressiveness, activity disturbances, hallucinations and paranoid features. Results also suggest that patients treated earlier with rivastigmine may attain a greater benefit compared with patients whose treatment is delayed 6 months. Further studies examining the effects of rivastigmine on behavioural disturbances in AD are therefore warranted.     

The Grossarth-Maticek and Eysenck Personality Types,Health-related behaviour,and indicators of transitory ill-health

The aim of this study was to scrutinize the relationship between personality type as described by Grossarth-Maticek and Eysenck, health-related behaviours, and indicators of transitory ill health in a community sample. The sample consisted of all per sons aged 40 years (45 men and 35 women) in a Swedish municipality who agreed to take part in a health examination at the primary health care centre of the municipality. The Short Interpersonal Reactions Inventory (Grossarth-Maticek and Eysenck, 1990) was used to measure personality type. Self-report data were obtained regarding seven health-related behaviours. Health was assessed in three ways; self-report (paper and pencil), self-report (interview response to physician), and measures of 36 biological variables including immune system indicators. The allocation of persons to the different personality types proved problematic using the established methods. By combining the types, according to Eysenck's personality model, and performing a cluster analysis on this combination, a ‘healthy’ and a ‘stressed’ profile were identified within both the male and the female group of subjects. Persons in the healthy personality cluster showed more favourable scores on the health-related behaviour indices and on the self-report health scales than the persons in the stressed cluster. They also tended to score lower than those in the stressed cluster on most of the biological markers known to increase during acute stress. The possibility that this implies a higher level of strain for the persons in the stressed cluster on various bodily systems is discussed.
