The integration of visual and functional classifications in concept formation

Summary Simple motor responses of different similarity were assigned to geometric figures of different similarity. Subsequently, subjects had to learn hierarchical classifications of visually similar or dissimilar figures which were associated with either similar or dissimilar responses. In this way, the visual and the functional similarity of the conceptually united figures were orthogonally varied. It was found that visually similar figures are conceptually classified fastest regardless of their functional similarity. In contrast, functional similarity has a considerable impact on the hierarchical classification of visually dissimilar figures. Functionally similar figures are conceptually faster classified than dissimilar ones. From the results we conclude that concepts are autonomously formed as mediating representations in stimulus-response coordinations. The hierarchical organization of concepts is thereby based on the sequential organization of both the visual input and the behavioral output. Further consequences of this approach are discussed.Portions of this research were presented at the International Symposium on Structure and Function of Human Memory, in Memoriam Hermann Ebbinghaus, Berlin, July 1985     

Die Bindungstheorie und ihre Relevanz für die Psychotherapie

Zusammenfassung Die ursprünglich von John Bowlby entwickelte Bindungstheorie gewinnt zunehmend an Relevanz im Bereich der Psychotherapie(forschung). Diese übersicht beginnt mit einer Kl?rung der zentralen Begriffe und Annahmen dieser Theorie und fa?t einige Befunde zur Entwicklung und den Korrelaten von Bindung zusammen, die vornehmlich aus entwicklungspsychologischen Untersuchungen stammen. übertragen auf Erwachsene, bedürfen die Konzepte der Bindungstheorie einer Revision, die in dieser Arbeit skizziert wird. Schlie?lich werden auf dieser Basis einige heute übliche Methoden zur Erfassung von Bindungsstilen und Bindungsverhalten im Erwachsenenalter dargestellt, die bei Untersuchungen im klinischen Feld (Inhalt des 2. Teils der übersichtsarbeit) eine wichtige Rolle spielen.      

An unobtrusive measurement method of the horizontal gaze angle

A horizontal gaze angle measurement device is introduced. By combining a photoelectric viewing device to measure the horizontal eye angle with a similar head angle measurement device, it is possible to measure the horizontal gaze angle without using a headrest. After discussion of circuit diagrams and measurement principles, it is shown that the measurements made with the device yield a reasonable precision. The mean absolute measurement error is below 1°. This inexpensive and unobtrusive device covers a visual field of about 20° and can be used in parallel with many tasks. Further, data on the successful application of the device in a driving simulation setting are discussed.     

Coping among children and adolescents with chronic illness

The present study was aimed to investigate age and gender effects on coping with everyday stressors among children and adolescents with chronic illness and healthy controls. Patients (8–13 years of age) with asthma (n=47), atopic dermatitis (n=52), and cancer (n=57) were compared to healthy controls (n=158) matched by age, gender, and grade. Self-report data on coping with academic and interpersonal stressors were collected. The primary results indicated that coping with everyday stressors was improved in children and adolescents with chronic illness compared to healthy controls. Thus, patients reported less passive avoidance on cross-situational coping and tended to show more situation-specific coping with social and school-related stressors than healthy controls. Additionally, among the clinical groups, patients with atopic dermatitis and cancer scored higher on positive self-instructions than patients with asthma. Conclusively, the results suggest that coping with a chronic illness may lead to more effective coping with everyday stressors. Implications for evaluating coping styles in patients with chronic illness are discussed.

Processing reduced word forms: the suffix restoration effect

Listeners cannot recognize highly reduced word forms in isolation, but they can do so when these forms are presented in context (Ernestus, Baayen, & Schreuder, 2002). This suggests that not all possible surface forms of words have equal status in the mental lexicon. The present study shows that the reduced forms are linked to the canonical representations in the mental lexicon, and that these latter representations induce reconstruction processes. Listeners restore suffixes that are partly or completely missing in reduced word forms. A series of phoneme-monitoring experiments reveals the nature of this restoration: the basis for suffix restoration is mainly phonological in nature, but orthography has an influence as well.     

Introducing LexTALE: A quick and valid Lexical Test for Advanced Learners of English

The increasing number of experimental studies on second language (L2) processing, frequently with English as the L2, calls for a practical and valid measure of English vocabulary knowledge and proficiency. In a large-scale study with Dutch and Korean speakers of L2 English, we tested whether LexTALE, a 5-min vocabulary test, is a valid predictor of English vocabulary knowledge and, possibly, even of general English proficiency. Furthermore, the validity of LexTALE was compared with that of self-ratings of proficiency, a measure frequently used by L2 researchers. The results showed the following in both speaker groups: (1) LexTALE was a good predictor of English vocabulary knowledge; 2) it also correlated substantially with a measure of general English proficiency; and 3) LexTALE was generally superior to self-ratings in its predictions. LexTALE, but not self-ratings, also correlated highly with previous experimental data on two word recognition paradigms. The test can be carried out on or downloaded from www.lextale.com .
