The bias and variability of staircase estimators were studied by means of repeated computer simulations of staircase runs. Both forced-choice and yes-no staircases were simulated. The influence of the shape of the psychometric function, the location and spacing of the stimuli, the number of trials in a run, and the method of deriving the estimate from the data are discussed. The forced-choice staircase is compared to the yes-no staircase, and the limitations of the simulation procedure are outlined. 相似文献

Differential sensitivity was measured before and after smoking a cigarette by 10 smokers, using 10 nonsmokers as controls. Stimuli consisted of reagent grade ethanol in eight concentrations ranging from 4% to 12%. No significant differences were observed between smokers and nonsmokers or before vs after smoking, although slightly higher overall correct responses and correspondingly smaller jnds were obtained for the nonsmokers. No practice affects were noted among the control group between the first and second set of samples. The findings confirm previous results which had been recently questioned. 相似文献

Zusammenfassung Mit Hilfe eines 2×2×2-Designs wurde die Wirkung der Anzahl der Signalflächen, Anzahl der irrelevanten Reize und Art der Motivation auf die Vigilanzleistung untersucht. Dabei zeigte sich, daß die Wahrscheinlichkeiten von verpaßten Signalen und falschen Alarmen mit der Anzahl der Signalquellen zunehmen. Die Menge der Nicht-Signale gleicher Modalität wie die Signalreize beeinflußt weder die Signalentdeckungen noch die falschen Alarme.Weiterhin wurde versucht, eine Systematisierung von Motivationswirkungen in Vigilanzaufgaben im Rahmen des detection-Modells vorzunehmen. Bei großen Gewinnen für richtige Signalentdeckungen und geringen Verlusten für falsche Alarme (Risiko-Motivation) ergab sich eine wesentlich höhere Entdeckungswahrscheinlichkeit und eine geringfügig höhere Rate von falschen Alarmen als bei geringen Gewinnen für richtige Signalentdeckungen und hohen Kosten für falsche Alarme (Vorsichts-Motivation). Weiterhin zeigte sich unter Risiko-Motivation ein Abfall der Entdeckungswahrscheinlichkeit und bei Vorsichts-Motivation ein Anstieg, während sich die entsprechenden Raten der falschen Alarme im Verlauf der Aufgabe nicht signifikant veränderten.

Experimental application of detection theory to vigilance behaviour
Summary In a 2×2×2-design the effects of number of dials, number of irrelevant stimuli and kind of motivation were combined. It was found out, that probabilities of missed signals and false alarms increased with spatial uncertainty. The number of irrelevant stimuli, which were of equal sensory modality as the relevant stimuli, had no influence either on detection probability or on false alarms rate.Further attempt was made to systematize effects of motivation on vigilance performance in the detection model. With great values for hits and small costs for false alarms (risky motivation) there was an essentially higher detection pobability and a slightly higher false alarms rate than with small values for hits and high costs for false detections (cautious motivation). The probabilities of detections decreased under risky motivation and increased under cautious motivation as the watch prolonged, whereas the corresponding probabilities of false alarms showed no significant changes.

Shared genes, shared experiences, and similarity of personality: data from 14,288 adult Finnish co-twins 总被引:2,自引:0,他引:2

Similarities for Extraversion (E) and Neuroticism (N) scale scores from the Eysenck Personality Inventory were evaluated in 7,144 adult twin pairs, drawn from the population-based Finnish Twin Cohort, as a function of the co-twins' genetic resemblance, gender, age, and the frequency of their social interaction with each other. To separate effects of shared genes from those of shared experience, we performed hierarchical multiple regressions of double-entry data matrices. Results establish the predictive significance of both genetic and experiential influences: Genetic effects remained significant when tested after the effects of social contact were first removed; conversely, for N scores, the effects of social contact remained significant when assessed after genetic influences were first removed. These findings establish genetic variance in major dimensions of adult personality but assign a significant role to common experience as well. The first finding constructively replicates reports by others; the second challenges the widespread assumption that shared experiences have a negligible impact on sibling similarity in adult personality. 相似文献

Intuition is an important part of a mature clinician's work. Yet, it is a component of clinical work which is looked upon with suspicion, due in part to the Middle-Age's association between intuition and the work of witches. This paper describes a tenuous link between intuition, witches, and Carl Whitaker. Patterns for including intuition in family therapy are discussed. 相似文献

Though similar to traditional group psychotherapy in many respects, a coping skill training approach differs principally in several areas and technically in many more. Coping skill training group therapy tends to employ many concrete intervention strategies to enhance various aspects of process, drawing on ongoing data to evaluate group interaction and individual responses. The approach draws more heavily on cognitive, modeling, reinforcement, and problem-solving procedures to achieve specifically determined goals, and it depends less on interpretive and confrontative methods. The author discusses a wide range of techniques to show the benefits of this approach. 相似文献
