In an exploration of the social impacts of treatments for hyperactivity, two age groups (kindergarteners and first-graders vs. fourth- and fifth-graders) heard about a hyperactive child whose problem was treated either by an internal and controllable means (effort) or by an external and uncontrollable means (medication) and whose behavior either did or did not improve. The attributions and affective responses of both age groups were influenced by both the nature and the effectiveness of treatment, and there was only weak support for the hypothesis that younger children are more influenced by treatment outcome than older children are. However, older children, conforming to attribution theory predictions, held target children more accountabe for the success or failure of their own efforts than for the outcomes of medication, particularly valuing the child whose own efforts succeeded. By contrast, young children judged the child whose efforts failed as more worthy of pride and more likable than the child whose medication failed. Implications for peer acceptance of hyperactive children over the childhood years are discussed.Portions of this paper were presented at the annual meeting of the Southeastern Psychological Association, Atlanta, March 1985. Thanks are extended to the staff and students of the Model Laboratory School. 相似文献

Though the term “new technology” is widely used and discussed, there has been very little systematic study of attitudes to
technology and their relation to other beliefs and group memberships. This article describes an initial investigation into
the nature of attitudes towards new technology (n=534 undergraduates) and demonstrates that, as yet, these attitudes are only weakly structured and are not fully integrated
with other social beliefs. General evaluations of the benefits of technological advance appear to be almost unrelated to beliefs
about the inevitability of these advances or the desire to acquire training to deal with them. Contrary to popular expectations,
evaluations of video games are unrelated to other beliefs about technology while other social beliefs are, as yet, only weakly
integrated with these attitudes. This study also identifies gender differences in the assessment of potential benefits and
highlights other differences attributable to academic group memberships. These finding are discussed with reference to the
literature on sex-role stereotyping and group socialization processes. 相似文献

Factors affecting spontaneous alternation behavior (SAB) in animals, for example, age, gender and species studied; type of
apparatus and cues employed; and neuro-anatomical, neuro-chemical and motivational status of the organism, were reviewed.
Despite a myriad of experiments showing interesting main effects of such variables, little research has been performed assessing
the interactive affects of these factors on alternation behavior. For example, psychologists test rats in central nervous
system (CNS) lesion studies, whereas psychopharmacologists tend to assess SAB in mice. Most importantly, studies have not
been reported investigating the possible interactions among species, brain lesions and drugs. This is an unfortunate omission
since several important alternation models include propositions relating to cholinergic and/or serotonergic coding in the
hippocampus. Examination of behavioral studies revealed the primary cue for alternation among invertebrates to be body turn,
whereas vertebrates rely primarily on directional and odor cues. Reference to the seeking of stimulus change remains the most
compelling motivational account of why animals manifest this ubiquitious and reliable behavior pattern.

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

This article is based on a review of recent literature on “computing stress”; that is, on the psychological stress effects
of working with computer systems. Current research into the sources of computer-related stress has tended to concentrate on
those employees who operate Visual Display Units (VDUs), either on a full-time professional basis as word-processor (WP) operators,
data-entry clerks, secretaries, or those dealing with enquiries from the public; or employees who use the VDU irregularly
as part of their other duties. A few studies have looked at specific occupation groups, such as printers (Kalimo & Lepp?nen,
1985), information technology professionals (programers and analysts), process workers, and college students (Sproull, Kiesler,
& Zubrow, 1984). Generally, however, research has been carried out on office workers, more often women, carrying out administrative
tasks. An attempt is made to identify those potential work-related stressors that have been isolated by these studies, and
also included are criticisms of the general methodologies used in many of them.
The terms “visual display unit,” “visual display terminal,” VDU, VDT, and “terminal” are used interchangeably. 相似文献

Brief presentations of letter arrays were probed by bar markers within or outside the fovea after various time delays. Figural
information presented to the foveal region was retained better under a photopic condition than information in the parafoveal
region, but under a scotopic condition parafoveal information demonstrated superior retention. However, decay rates over time
of all functions were similar, demonstrating that figural information in the rods and cones decays at similar rates. 相似文献

Newcombe, Bandura, and Taylor developed a questionnaire measuring participation in space-related activities. The activities were classified as masculine, feminine, or neutral in gender stereotyping. A short version of this questionnaire was developed based on an item analysis of the responses by 485 introductory psychology students (236 women and 249 men). The 10 masculine, 10 feminine, and 10 neutral items chosen for the short form were given to 60 subjects (28 women and 32 men), along with a measure of spatial performance (Piaget's water-level task). Reliabilities (by coefficient alpha) were .79, .77, and .75, for the masculine, feminine, and neutral activity subscales, respectively. As with the original scale, women had a greater preference than men for feminine activities, men had a greater preference than women for masculine activities, and women and men had an equal preference for neutral activities. Masculine activity preference was associated with better water-level performance, with the relationship significantly stronger for women (r=.50) than for men (r=.10). Uses for the questionnaire in research on sex-related differences in spatial performance are suggested. 相似文献

In order to examine the possibility that the attribution of more aggression to boys may be in part a function of observer bias, 40 adults were asked in Study 1 to record the degree of aggression in a series of line drawings that showed children interacting. It was found that a significant subset of both males and females recorded more aggression for boys than for girls when they scanned scenes that showed numerous children interacting. When they rated a series of drawings of two children interacting, males rated boys as significantly more aggressive than girls. Study 2 examined 48 adults' responses under one of three instruction conditions. The findings of Study 1 were replicated. Additionally, it was found that some forms of instruction eliminate sex-typed biases while others yield significant biases among both male and female untrained observers. These results are interpreted in light of the literature on schematic processing. Implications pertaining to the socialization of aggression and to research on sex differences in aggression are discussed. 相似文献
