This study aimed to evaluate a peripheral serotonergic marker, 3H-imipramine (3H-IMI) binding to platelet membranes, in a group of severely aggressive subjects (A), institutionalized since childhood for mental retardation, as compared with suicide attempters (S) and healthy controls (H). The maximum binding capacity of 3H-IMI to platelet membranes was statistically lower in (A) and (S) than in (H). In addition, a statistically significant difference was observed between the Bmax values of aggressive subjects and those of suicide attempters. No changes in the dissociation constant (Kd) of IMI binding were observed. These data provide further supporting evidence for the hypothesis of an abnormality of the 5HT system in aggressive behaviour and suggest that such an abnormality, as reflected by platelet markers, is more severe in suicide attempters. © 1993 Wiley-Liss, Inc. 相似文献

Destination memory, a memory component allowing the attribution of information to its appropriate receiver (e.g., to whom did I lend my pen?), is compromised in normal aging. The present paper investigated whether older adults might show better memory for older destinations than for younger destinations. This hypothesis is based on empirical research showing better memory for older faces than for younger faces in older adults. Forty-one older adults and 44 younger adults were asked to tell proverbs to older and younger destinations (i.e., coloured faces). On a later recognition test, participants had to decide whether they had previously told some proverb to an older/younger destination or not. Prior to this task, participants reported their frequency of contact with other-age groups. The results showed lower destination memory in older adults than in younger adults. Interestingly, older adults displayed better memory for older than for younger destinations. The opposite pattern was seen in younger adults. The low memory for younger destinations, as observed in older adults, was significantly correlated with limited exposure to younger individuals. These findings suggest that for older adults, the social experience can play a crucial role in the destination memory, at least as far as exposure to other-age groups is concerned. 相似文献

The influence of dopaminergic replacement (DR) on gait in people with Parkinson's disease (PD) is well documented. However, little is known about the acute effects of dopamine on more complex locomotor tasks that require visual guidance to avoid obstacles during gait. The authors investigated the influence of DR on locomotor behavior in a task where movement planning and control might be challenged by the height of the obstacle. The PD group included patients diagnosed with idiopathic PD (n = 12), as well as healthy controls (n = 12). Patients walked and stepped over obstacles of different heights before (OFF) and after (ON) levodopa intake. Spatial adjustments were not modulated by DR, but the step time to perform these anticipatory gait adjustments was longer only in PD-OFF (compared with healthy controls) when approaching the highest obstacle, but not PD-ON. During the crossing phase, trail limb toe clearance of PD patients was shorter than healthy controls only during the OFF state. ON-OFF comparisons were significantly different only for the time to reach the lead foot clearance over the highest obstacle. In summary, DR partially improved movement slowness but did not directly affect movement amplitude of lower limb regulation in this gait task. 相似文献

Abstract The field of paradoxical therapy has mushroomed in a variety of conceptual and methodological ways. One of the latest methods is the use of paradoxically worded letters that will be given to couples and families, usually at the outset of therapy. To check on the validity of this approach, 56 couples were evaluated before and after a course of six sessions of marital enrichment. One group received no enrichment. A second group received enrichment. A third group received linearly worded messages at the end of the fourth session of enrichment, while a fourth group received paradoxically worded messages. The effect of these messages on the outcome is analyzed and discussed. 相似文献

The purpose of this study is to validate a relational, contextual selfhood model of psychopathology with the MMPI-2. Positive and negative attributions of importance to self and intimate others were hypothesized as producing four personality propensities: a functional one, self-fullness, and three dysfunctional ones or extreme deviations, selfishness or externalization, selflessness or internalization, and no-self and psychopathology. These propensities have meaning specifically in intimate (committed, prolonged, and close) relationships and may not generalize to public, short-lived, or superficial, ones. Four algorithms, composed from validity and clinical scales of the MMPI-2, evaluated whether the four personality propensities of the model can be validated with the MMPI-2. An early study using undergraduates gave some support for the reliability of classifications obtained from the four algorithms. However, the use of nonclinical cases and the lack of an external criterion to evaluate level and type of psychopathology required a larger sample of clinical cases and the use of an external criterion. Both criteria were met with a much larger clinical sample with one external criterion about type and extent of psychopathology, the Multiaxial Diagnostic Inventories (MDI) using ratings by respondents themselves and diagnoses by psychologists evaluating them. The results of the MDI tended to support possible links between the relational model and an empirical test like the MMPI-2. 相似文献

Abstract Family psychology differs from family therapy on a variety of dimensions. Philosophically, family psychology emphasizes the relationship of the individual to the family rather than considering the family as a system, deemphasizing the individual, as in systems family therapy. In addition, family psychology is interested in the whole spectrum of functionality-dysfunctionality, while family therapy is interested mainly in dysfunctional families. Substantively, in terms of differences in training, family psychology stresses the importance of theory testing, evaluation of process and outcome of interventions, and prevention with functional or at-risk families. An academic curriculum in family psychology, which has been operational at Georgia State University for the last 10 years, is presented. Clinical training follows a gradual approach, starting with relatively simple Structured Enrichment, progressing to more complex training in Covenant Contracting and Systematic Homework Assignments, and finally family therapy. 相似文献

This paper is an attempt at introducing a formal framework for societal, participative, anticipatory, inner‐change oriented and open‐ended ‘’ learning for evolution.” The key point of our approach is that it considers the evolution of a social system not exclusively as an appropriate result of the given system structure, operating and behaving under external constraints; but mainly as an outer (or observable) consequence of some inner changes brought about from within the system of heterogenous actors‐designers in their effort to cope with complexities generated equally by external constraints and by the network of mutual relationships between them. The actors‐designers are thus trying to assess critically the courses the system could possibly take in the future and also to isolate —through a dialogue between them—the so‐called “evolutionary” ones. Consequently, a policy‐oriented approach to “social homcorhesis” is obtained. It opens the way to a participative planning outlook on societal learning. 相似文献

Emotional and affective processing imposes itself over cognitive processes and modulates our perception of the surrounding environment. In two experiments, we addressed the issue of whether nonconscious processing of affect can take place even under deep states of unawareness, such as those induced by interocular suppression techniques, and can elicit an affective response that can influence our understanding of the surrounding environment. In Experiment 1, participants judged the likeability of an unfamiliar item—a Chinese character—that was preceded by a face expressing a particular emotion (either happy or angry). The face was rendered invisible through an interocular suppression technique (continuous flash suppression; CFS). In Experiment 2, backward masking (BM), a less robust masking technique, was used to render the facial expressions invisible. We found that despite equivalent phenomenological suppression of the visual primes under CFS and BM, different patterns of affective processing were obtained with the two masking techniques. Under BM, nonconscious affective priming was obtained for both happy and angry invisible facial expressions. However, under CFS, nonconscious affective priming was obtained only for angry facial expressions. We discuss an interpretation of this dissociation between affective processing and visual masking techniques in terms of distinct routes from the retina to the amygdala. 相似文献
