Detection and identification thresholds for consonant-vowel syllables

Detection and identification thresholds were obtained for 6- and 10-year-old normal children and normal adults using five-formant synthesized consonant-vowel ([baHdflrfea]) stimuli. Sixyear-old children were found to have poorer detection than adults, just as they do for pure tones. For the identification task, the slopes of the performance-intensity functions were more shallow for 6-year-old children than for 10-year-olds and adults. Consequently, compared with 10-yearolds and adults, 6-year-old listeners require a greater increase in stimulus intensity above detection threshold to identify these stimuli at a high performance level. The influence of acoustic characteristics of the stimuli on all listeners is also discussed.     

Kommunikationsstruktur und Gruppenleistung

Zusammenfassung Vierergruppen von Vpn arbeiteten in Kommunikationsnetzen, in denen es infolge des Fehlens einer (direkten oder indirekten) Wechselseitigkeit gewisser Verbindungen einigen Vpn — nämlich denjenigen, die ganz bestimmte (ungünstige) Positionen innerhalb des Netzes einnahmen — verwehrt war, die Lösung eines Problems durch Austausch von Informationen zu finden. Den Vpn-Gruppen wurde diese Eigenschaft der Kommunikationssysteme bei Beginn der Versuche nicht mitgeteilt. In einer derartigen Lage suchen jene Vpn den Grund für den unbefriedigenden Informationsaustausch (zumindest zunächst) nicht in der Struktur des Kommunikationsnetzes, sondern unterstellen den anderen Gruppenmitgliedern mangelnde Loyalität oder/und mangelndes Verständnis. Die Folge sind starke affektive Spannungen, die zur Verschlechterung der Kooperation und zur Verringerung der Gruppenleistung führen. Die kognitive Seite des Erlebens der Vpn wurde u. a. mit Hilfe der Begriffe phänomenale Variabilität und phänomenale Konstanz näher analysiert.

Employee Cynicism and Resistance to Organizational Change

We offer a reconceptualization of employee cynicism and present the results of two studies to test the hypotheses that (a) cynicism about an organizational change is distinguishable from skepticism about the change, more general forms of cynicism (disposition and management), and trust in management, (b) change-specific cynicism and skepticism relate differently to personal and situational antecedent variables, and (c) change-specific cynicism accounts for variance in employees intention to resist change not explained by skepticism, trust, and more general forms of cynicism. Study 1 was conducted with employees (N=65) from several organizations undergoing various changes, and Study 2 with employees (N=701) from a single organization undergoing restructuring and culture change. Results were generally consistent with prediction. Implications for future research and for the management of change are discussed.     

Well-being in major depression and social phobia with and without comorbidity

Background/Objective: Lower levels in well-being have been observed in individuals with Major Depression (MDD) and Social Phobia (SP), but well-planned direct comparisons with control individuals, not suffering from a mental disorder, are lacking. Furthermore, MDD is highly comorbid with anxiety disorders, and SP with depressive disorders. This study is among the first to examine differences in well-being in individuals with a clinical diagnosis of MDD or SP compared to individuals with no such diagnosis and to test differences in well-being within the combined diagnostic categories respective with and without anxiety-depressive comorbidity. Method: Participants were 119 individuals with a diagnosis of MDD, 47 SP and 118 controls. Results: Results revealed that overall well-being as well as emotional, psychological, and social well-being were lower in the MDD and SP group compared to the control group. Individuals with comorbidity reported lower well-being than individuals without comorbidity. Conclusions: These findings have clinical implications as presence of comorbidity may require a different therapeutic approach than with no comorbidity.
