Pigeons were exposed to two different reinforcement schedules under different stimulus conditions in each of two daily sessions separated by 6 hr (Experiments 1 and 2) or in a single session (Experiment 3). Following this, either a fixed-interval (Experiment 1) or a variable-interval schedule (Experiments 2 and 3) was effected in both stimulus conditions. In the first two experiments, exposure to fixed-ratio or differential-reinforcement-of-low-rate schedules led to response-rate, but not pattern, differences in subsequent performance on fixed- or variable-interval schedules that persisted for up to 60 sessions. The effects of reinforcement-schedule history on fixed-interval schedule performance generally were more persistent. In Experiment 3, a history of high and low response rates in different components of a multiple schedule resulted in subsequent response-rate differences under identical variable-interval schedules. Higher response rates initially occurred in the component previously correlated with high response rates. For 3 of 4 subjects, the differences persisted for 20 or more sessions. Previous demonstrations of behavioral history effects have been confined largely to between-subject comparisons. By contrast, the present results demonstrate strong behavioral effects of schedule histories under stimulus control within individual subjects. 相似文献

Debbie, a patient in ongoing therapy, volunteered to assist in a workshop by participating in an interview. The goals of the session were to identify some small, discrete problem that could be worked on in the limited time available, and to demonstrate how a short-term treatment can be used.The issues considered revolved around Debbie's schema. Her early abuse set several schemas that have directed Debbie's life. The goals of the therapy would be to help modify those rules. The single session was a microcosm of a longer-term therapy. Overall, from the reports of the patient and her therapist, on follow-up, she was able to do the homework with the the therapist's assistance and found that it was helpful in countering the negative thoughts. This led to a lifting of the concomitant depression and a diminution in the self-injurious behavior.Many sessions would be needed to reinforce and strengthen the exercise strated in this session. Overall, I would see this session as both a successful treatment session and a demonstration of how identifying discrete, proximal goals can benefit patients with long-standing Axis II problems. The hypotheses and questions led to data gathering and hypothesis testing. Throughout the session, it was essential to be aware of the likely schemas so that some could be used in the session, while others were clearly avoided. By developing a conceptualization or model of the problem(s), a set of interventions could be mobilized within the session and as homework between sessions. By working toward a coping model of treatment rather than attempting to cure long-standing problems, brief cognitive behavioral interventions can be successful. 相似文献

The Millon Clinical Multiaxial Inventory (MCMI) is a promising, yet somewhat unproven psychometric inventory developed to identify clinical syndromes and personality traits consonant with the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III]; American Psychiatric Association, 1980). The stability of its measures for both the theoretically more stable personality characteristics and the clinical syndromes was investigated in a group of depressed psychiatric outpatients. In this test-retest design with a 3-month interval between tests, clinical syndrome scales of relevance changed significantly as expected. However, many of the personality scales also changed significantly. Only four of the personality scales met a two-fold test of stability. Findings are discussed in terms of characteristics of self-report inventories such as the MCMI, the uniqueness of the depressed population, and characteristics of personality disorders. 相似文献

Two cases of onset of stuttering subsequent to laryngectomy are reported. These patients demonstrate that the existence of a larynx is not necessary for the generation of stuttering. The findings support the hypothesis that neuromotor control of sound source (laryngeal or alaryngeal) plays a critical role in the generation of stuttering-type dysfluencies and, perhaps, even in the onset of stuttering. They also suggest that dramatic alteration in sound source has the potential for dramatically altering fluency. 相似文献

Summary Linear retinal perspective as a cue for visual slant and shape is analyzed in terms of its geometrical and psychophysical properties. Geometrically, retinal perspective is defined as the visual-angle difference in the projective magnitudes of the near and far edges of slanted rectangles. The psychophysical effectiveness of retinal perspective is then determined in two experiments. In Experiment 1, the sensitivity of the eye to retinal perspective is shown to be inversely related to the visual-angle height of slanted rectangles which are rotated about a horizontal axis. In Experiment 2, the visual shape of monocularly observed slanted rectangles is shown to depend solely on a simple prediction derived from Weber's Law, in which it is assumed that perceived height is a linear function of visual-angle height.

Zusammenfassung Die geometrischen und psychophysischen Eigenschaften der linearen retinalen Perspektive wurden analysiert, um festzustellen, welchen Einfluß die Perspektive auf gesehene Schräge und Form hat. Geometrisch wird die retinale Perspektive als die Sehwinkeldifferenz in der projektiven Größe der näheren und ferneren Kante schräger Rechtecke definiert. Die psychophysische Wirksamkeit der retinalen Perspektive wurde an Hand zweier Experimente gemessen. Im ersten wurde gezeigt, daß die Sensitivität des Auges für die retinale Perspektive eine negative Funktion der Sehwinkelhöhe schräger Rechtecke ist, wenn diese um eine waagerechte Achse gedreht sind. Im zweiten Experiment wurde festgestellt, daß die Sehform einäugig betrachteter schräger Rechtecke von einer einfachen Ableitung des Weberschen Gesetzes abhängig ist, in der angenommen wird, daß die wahrgenommene Körperhöhe des Rechteckes eine lineare Funktion der Sehwinkelhöhe des Retinabildes ist.
