Native Hawaiian high school students, N = 1779, were surveyed for symptoms of psycho-pathology and suicide attempts in the previous 6 months. Seventy-seven (4.3%) of the students reported making a suicide attempt. There were no significant differences in prevalence rates for males and females. Depression, anxiety, aggression, substance abuse symptoms, and low family support, but not peer support, were significantly correlated with suicide attempts. On logistic regression, depression, substance abuse, and family support independently predicted attempts. The lack of gender difference may indicate a cultural characteristic of the Hawaiian population that differentiates it from mainstream American populations but likens it to the Native American population. 相似文献

Visual cognitive differences between hearing (N = 16) and deaf (N = 32) high-school and middle-school students were studied. Visual tasks were presented on a microcomputer and response latencies were collected. Significant differences were noted between the deaf and normal groups but not between total communication deaf and oral deaf students. These differences support the hypothesis that deaf students prefer a visual cognitive strategy. Implications for educating the deaf are discussed. 相似文献

Understanding the analyst's work and its vicissitudes has been a major focus of recent psychoanalytic writing. This study on slips of the analyst represents an attempt to advance our understanding of analytic work. The slips described support the view that slips reflect not simply contributions from instinctual life, but active work-related goals of the analyst in carrying out the analytic tasks. Countertransference is discussed as reflected in the disturbance of intentionality betrayed by the occurrence of a slip. The essential role of the analyst's understanding his or her own reactions is emphasized. 相似文献

Three untested assumptions of the impulse-variability model were examined in two experiments utilizing rapid, uni-planar limb movements. Experiment 1 varied movement distance (A) and movement time (MT) in a rapid-timing paradigm where the subject moved a lever through a certain distance in a certain time. Experiment 2 varied A in a reversal response where the S made a rapid elbow flexion and extension in a given MT. Displacement recordings were made on every trial. KR (knowledge of results) about MT was given after every trial. The results can be summarized as follows: (a) As predicted by the model, variations in impulse size and velocity were directly related to the impulses size; (b) There was no correlation between the accelerative and decelerative impulse durations recorded during the reversal response supporting the notion that the impulses might be independent; (c) Negative correlations (-.20 to -.50) were demonstrated between peak acceleration and impulse duration for both experiments, counter to the predictions of the model; and (d) Counter to the predictions of the model, timing error (VEt) increased as A decreased for rapid-timing responses. When the correlational results are taken into account, the model has the capacity to account for curvilinear relationships between relative timing error and movement speed. Overall, the results suggest that the impulse variability model requires some restructuring before it can be considered a viable model for the control of rapid limb movements. 相似文献

A total of 189 male Vietnam veterans who were admitted to a specialized inpatient treatment program were evaluated using the Millon Clinical Multiphasic Personality Inventory to assess character styles. The veterans were assessed for Posttraumatic Stress Disorder by using a subscale of the Minnesota Multiphasic Personality Inventory (MMPI) and 72% of the patients were classified as having Posttraumatic Stress Disorder. The character styles of passive-aggressive, schizoid, avoidant, and borderline were significantly associated with these patients. The most common 2-point profile was passive-aggressive and avoidant (8-2 or 2-8) and was significantly related to the diagnosis. While drug and alcohol abuse were common problem areas for the entire sample, the profile of patients with Posttraumatic Stress was different from those of substance abusers. These results indicate that treating Vietnam veterans with this disorder requires adopting strategies which include a character style focus as well as a symptom focus. 相似文献

Although the effects of attention on movement execution are well documented behaviorally, much less research has been done on the neurophysiological changes that underlie attentional focus effects. This study presents two experiments exploring effects of attention during an isometric plantar-flexion task using surface electromyography (sEMG). Participants' attention was directed either externally (towards the force plate they were pushing against) or internally (towards their own leg, specifically the agonist muscle). Experiment 1 tested the effects of attention on accuracy and efficiency of force produced at three target forces (30, 60, and 100% of the maximum voluntary contraction; MVC). An internal focus of attention reduced the accuracy of force being produced and increased cocontraction of the antagonist muscle. Error on a given trial was positively correlated with the magnitude of cocontraction on that trial. Experiment 2 tested the effects of attention on muscular fatigue at 30, 60 and 100%MVC. An internal focus of attention led to less efficient intermuscular coordination, especially early in the contraction. These results suggest that an internal focus of attention disrupts efficient motor control in force production resulting in increased cocontraction, which potentially explains other neuromechanical findings (e.g. reduced functional variability with an internal focus). 相似文献
