Although the parietal lobe is not traditionally thought to support declarative memory, recent event-related fMRI studies of episodic retrieval have consistently revealed a range of memory-related influences on activation in lateral posterior parietal cortex (PPC) and precuneus extending into posterior cingulate and retrosplenial cortex. This article surveys the fMRI literature on PPC activation during remembering, a literature that complements earlier electroencephalography data. We consider these recent memory-related fMRI responses within the context of classical ideas about parietal function that emphasize space-based attention and motor intention. We conclude by proposing three hypotheses concerning how parietal cortex might contribute to memory. 相似文献

This is the first reported research that explores the feeling of knowing (FOK) for musical stimuli. Subjects attempted to recall melodies and titles of musical pieces, made FOK ratings when recall failed, and then had a recognition test. With instrumental music (Experiment 1), more titles were recalled when melodies were given as cues than vice versa. With songs whose lyrics were not presented (Experiment 2), however, more melodies were recalled than were titles. For nonrecalled items, although the overall levels of recognition did not differ, FOK ratings were higher for titles than for melodies in Experiment 1, and the opposite pattern occurred in Experiment 2. In both experiments, the FOK ratings predicted melody recognition more accurately than they did title recognition. 相似文献

This paper describes a transducer that allows for the concurrent recording of outer eyelid closure on both the left and the right eyes of a rabbit. The device makes use of voltage induced across a current-carrying conductor when the conductor is exposed to a magnetic field perpendicular to its axis (the Hall effect). The transducer is relatively compact, inexpensive, and allows the animal to be loosely restrained. 相似文献

This paper explores the utility of relapse prevention therapy (RPT) for transplant candidates with substance use disorders. Similarities and differences between this population and the general substance abuse patient population are discussed and suggestions are made for modifying the RPT treatment protocol. Major issues include the source and intensity of motivation for treatment, the nature of the therapeutic relationship, the type and severity of psychosocial consequences that may have been experienced as a result of substance use, and the patient's perception of the problem (addiction versus liver disease). Recommendations are made to provide empathy and support around medical concerns, motivate them for sobriety, and work to build collaborative relationships between team members and patients. Patients need to see the RP therapists as working to help them maintain sobriety and obtain a transplant, not as policing their drug use. 相似文献

We analyzed a sample of 356 forms containing information that Colorado law legally requires both licensed and unlicensed therapists to disclose to clients. The majority of forms contained the legally mandated information; fewer forms contained ethically desirable information. The average readability grade level was 15.74, corresponding to upper-level college, and 63.9% of the forms reached the highest (most difficult) readability grade of 17+. Therapists are obeying the law, but do not appear to be taking advantage of the opportunity to provide their clients useful information in an accessible way. 相似文献

Examined the roles of gender, instrumentality, and expressivity as moderator of the relations between stressful events and psychological symptoms in samples of junior high (n = 93), senior high (n = 140), and college students (n = 145). Female adolescents in all three samples reported more overall negative events than did males. Females in the junior and senior high samples reported more negative interpersonal stresses than did males. However, there were no indications in any of the samples of a stronger relation between negative events and psychological symptoms for adolescent females than males. Further, there was little evidence that instrumentality or expressivity moderated the relations between negative events and psychological symptoms. In each sample, certain stresses were most strongly related to psychological symptoms: family stresses in the junior high, peer stresses in the senior high, and academic stresses in the college sample. Implications of the findings for developmental changes in stress during adolescence are discussed. 相似文献

To examine the ability of the expectancy-based personality dimensions dispositional optimism and perceived control over stress to predict the ways in which people characteristically attempt to cope with stress, 420 undergraduate students completed the Life Orientation Test (LOT; Scheier and Carver, 1985), a measure of perceived control over stress, and the dispositional version of the COPE Inventory (Carver, Scheier and Weintraub, 1989). The results revealed a modest but reliable positive correlation between optimism and the perceived control measure. Principal-components analysis of the COPE revealed a factor structure which was generally in accord with prior research. Optimism was positively correlated with active coping and positive reinterpretation, and negatively correlated with focusing on and venting of emotion. Perceived control over stress was negatively correlated with behavioural disengagement. Implications and directions for future research are discussed. 相似文献

The purpose of the present study was to determine if lingual vibrotactile threshold shifts occurred during magnitude-estimation scaling of suprathreshold stimuli presented to the dorsal surface of the tongue. Possible relationships of the lingual vibrotactile threshold shifts to suprathreshold stimulus intensity, magnitude-estimation responses, and overall scaling behavior were explored. A single group of 24 subjects with an age range of 18 to 22 years participated in this study. Each subject performed two magnitude-estimation tasks. In one of the tasks, threshold of sensitivity was determined after every suprathreshold numerical response of the subject. If a threshold shift was recorded, threshold was allowed to return to the pretest baseline level before continuing to the next suprathreshold stimulus presentation. The results showed that threshold shift did occur during lingual vibrotactile magnitude-estimation scaling, and that it was related to suprathreshold stimulus intensity. The results also showed that the numerical magnitude-estimation responses of the subjects were different for the two scaling tasks. Overall scaling behavior of the subjects in the form of power-function exponents was not different for the two tasks. 相似文献

The purpose of this investigation was to determine the effectiveness of the Hand Test (Wagner, 1962/1983) in differentiating among mentally retarded adults placed in community housing versus those discharged from an institution due to violent and destructive behavior. Hand Test protocols of 24 mentally retarded adults who were discharged from an institution for violent and destructive behavior were compared with those of 12 mentally retarded adults who were placed in community housing, with regard to the presence of two indices of aggressive behavior (the acting-out score, AOS, and the movement response, ACT-MOV). Results indicated that 20 of the 24 residents discharged for aggressive behavior manifested one or more of the signs, whereas only 3 of the 12 residents discharged to a less restrictive environment exhibited one or more of the signs. The findings further demonstrate the usefulness of the Hand Test in predicting violent and destructive behavior in an institutional setting. 相似文献
