In a sample of 100 four-letter words, there was more information about the identity of the words in the first letter than in the last letter. However, information asymmetry did not correlate with visual field differences in a lexical decision study. It therefore may be possible to use horizontally displayed short words in visual field studies without being concerned about peripheral factors. Different factors affect the recognition of vertical and horizontal displays, and the use of vertical displays is not advised. 相似文献

Type A and Type B male college students were given the opportunity to display hostile aggression against an insulting confederate on a bogus ESP task, using either aversive noise or a monetary penalty. Preliminary correlational analyses confirmed that Ss' aggressive responding covaried directly with their reported desire to hurt the confederate but was, in contrast, unrelated to their reported desire to help the confederate. Thus, Ss' aggressive behavior was motivated by hostile intentions. Subsequent analyses revealed that Type As were more aggressive and reported a greater desire to hurt the confederate than Type Bs, regardless of the mode of aggression. These data support the results of a recent study which questioned the intuitively appealing assumption that Type As should only display aggressive behavior when motivated by some external achievement goal. 相似文献

The social adjustment of the adolescent offspring of parents with bipolar affective disorder (n=41) was compared to that of the offspring of parents with nonaffective psychiatric disorders (n=22) and the offspring of normal controls (n=26). In addition, the relationship between social adjustment and cyclothymia in offspring was determined. Social adjustment was assessed using the Life Activities Inventory, a new measure developed to assess social functioning in adolescents and young adults. Cyclothymia was assessed with the General Behavior Inventory. As a group, the offspring of bipolar parents did not differ significantly from either control group on social adjustment. However, the cyclothymic offspring of bipolar parents exhibited significantly poorer social adjustment than the noncyclothymic offspring of bipolars and the offspring of psychiatric and normal controls. These findings suggest that poor social functioning in the adolescent offspring of parents with bipolar illness may be associated with the early manifestations of affective disorder. In addition, these data indicate that despite its subsyndromal intensity, cyclothymia can result in significant social impairment.This study was supported in part by National Institute of Mental Health (NIMH) Research Grant MH-39782 to Daniel N.

Inpatient Multimodal Therapy (imt) is a residential treatment program, lasting a maximum of 36 weeks, for patients with severe neurotic symptoms. A group of
44 chronic obsessive-compulsive patients and a group of 40 chronic phobic patients were treated in order to assess the outcome
and the process of treatment and to identify prognostic factors associated with the effect. At follow-up—on average, eight
months after discharge—it was found that 60% had improved, 32% had remained the same, and 8% had deteriorated, indicating
that, in general, the treatment was beneficial. That these effects were long-lasting is supported by the fact that, at follow-up,
78% of all patients were no longer receiving treatment, 18% were receiving outpatient or day treatment, and 4% were receiving
inpatient treatment. Phobic patients appear to have gained more from the multimodal approach than did obsessive-compulsive
patients, as indicated by the fact that the severity of symptoms decreased as they improved in rational thinking, assertiveness,
and arousal. By contrast, obsessive-compulsive patients relapsed more than phobic patients did. This was attributed to the
fact that the former gained less from the rational-emotive training, denied problems with assertiveness, and did not practice
the acquired relaxation skills. It further appeared that a favorable outcome could be induced in patients who (1) expressed
relatively mild symptoms in this otherwise severe group, (2) reported relatively few additional complaints, (3) could clearly
indicate interpersonal problems, and (4) did not use psychotropic drugs. These prognostic factors are so widespread that not
much weight can be ascribed to them. Yet they are useful for indication ofimt until better predictors are found. 相似文献
