Two studies provide evidence that, in friendships, people offer support to partners more often than they request identical support for themselves. In one study, people reported being more likely to offer different types of support (e.g., a ride to a train station) than to request identical support. This effect was more pronounced for casual than established friendships. In a second study, people assigned randomly to be in a position to give support or to seek identical support from a friend gave more support than they sought. The observed asymmetry is attributed to people balancing desires to establish and strengthen communal relationships against desires to protect the self from rejection, not to people being inherently more unselfish than selfish.  相似文献

Social disorganization theory suggests that certain school-level indictors of disorder may be important predictors of bullying-related attitudes and behaviors. Multilevel analyses were conducted on bullying-related attitudes and experiences among 22,178 students in 95 elementary and middle schools. The intraclass correlation coefficients indicated that 0.6–2% of the variance in victimization, 5–10% of the variance in retaliatory attitudes, 5–6% of the variance in perceptions of safety, and 0.9% of the variance in perpetration of bullying was associated with the clustering of students within schools. Although the specific associations varied somewhat for elementary schools as compared to middle schools, the hierarchical linear modeling analyses generally suggested that school-level indicators of disorder (e.g., student–teacher ratio, concentration of student poverty, suspension rate, and student mobility) were significant predictors of bullying-related attitudes and experiences. Student-level characteristics (i.e., sex, ethnicity, status in school) were also relevant to students’ retaliatory attitudes, perceptions of safety, and involvement in bullying. Implications for school-based research and violence prevention are provided.  相似文献

D Lindsey 《Adolescence》1975,10(39):337-352
In this section we have assembled a small collection of data concerned with the issue of whether or not adolescents would profit from reflective inquiry into the closed area of mental health care. We have analyzed, arranged and interpreted the data from our study and conclude it demonstrates that adolescent inpatients did profit substantially from a reflective inquiry into mental health care. The number of subjects involved in this experimental program was small. The subjects of the experimental program were not selected randomly. Moreover, the researcher could not control for a number of intervening variables. For this particular group the intervening variables were many: changes in the subjects' individual treatment program, level of tranquilizing medication, attitude of other staff toward the experimental program, relations with parents or relatives, et cetera. This list covers some of the more important weaknesses of the experimental design. In the account of the experiment we reported the influence of other significant intervening variables as they emerged during the course of the study. Even with these important limitations the total push of the results in the direction of our argument compels us to conclude that it is clearly profitable for adolescent inpatients to reflectively inquire into the closed area of mental health care. Although the data reported here are not of predictive value, we believe they indicate the importance of having adolescent inpatients reflectively examine their social situation.  相似文献

In samples of 30 Canadian and 117 American undergraduates, academic performance was more strongly correlated with perfectionism scores (Revised Almost Perfect Scale) (r = .20 and -.17) than with those on self-reported depression (CES-Depression) (r = -.09).  相似文献

Distraction for Pediatric Immunization Pain: A Critical Review   总被引:2,自引:0,他引:2  
The paper provides a critical review of distraction for pediatric immunizations in order to determine clinical practicality and efficacy of this commonly employed intervention. The MEDLINE and PsycINFO databases were searched to identify papers that included an evaluation of a distraction intervention as a method of pediatric immunization pain management. Fifteen papers were included in this review. Effect sizes were calculated to estimate the clinical significance of findings. In order to examine possible differences in effect sizes related to distraction characteristics, chi square analyses were conducted. Results indicate that distraction is clinically effective in the reduction of pain during pediatric immunizations. Support is found for behavioral and cognitive explanations of distraction mechanisms. Further, various distraction stimulus characteristics were found to be associated with the clinical significance of findings. This article is based on the preliminary examination paper of the first author under the direction of the second, at West Virginia University.  相似文献

The application of the power-spectrum model of masking to the detectability of a signal masked by dichotic noise was investigated in three experiments. In each experiment, the signal was a 2-kHz sinusoid of 400-msec duration, masked by either one or two 800-Hz wide bands of noise presented singly or in pairs. In Experiment 1, we compared the detectability of a diotic signal masked by dichotic noise with the detectability of a monaural signal masked by each of the noises separately. The spectrum level of the noise was 35 dB SPL. For dichotic presentations, the signal was sent to both ears while pairs of noise bands, one below and one above the signal frequency, were presented together, one band to each ear. Threshold levels with the dichotic stimuli were lower than or equal to the thresholds with either ear's stimulus on its own. Similar dichotic stimuli were used in Experiment 2, except that the signal frequency was nearer to one or the other of the bands of masking noise, and the noise had a spectrum level of 50 dB SPL. In Experiment 3, thresholds were obtained with two sets of symmetrically and asymmetrically placed notched-noise maskers. For one of these sets, the spectrum level of both noise bands was 35 dB SPL; for the other set, interaural intensity differences were introduced in the form of an inequality in the levels of the noise bands on either side of the signal. In one ear, the spectrum level of the lower frequency noise band was 35 dB SPL and the spectrum level of the higher frequency noise band was 25 dB SPL, whereas in the other ear, the allocation of noise level to noise band was reversed. The dichotic thresholds obtained with the unequal noise maskers could be predicted from the shapes of the auditory filters derived with equal noise maskers. The data from all three experiments suggest that threshold signal levels in the presence of interaural differences in masker intensity depend principally on the ear with the higher signal-to-masker ratio at the output of its auditory filter, a finding consistent with the power-spectrum model of masking.  相似文献

The effect of stimulus range and stimulus spacing was examinedwhen subjects registered the perceived intensity of sweet liquids using either a matching procedure (Experiment 1) or category rating (Experiment 2). The matching procedure is conceptually similar to absolute magnitude estimation, whereby subjects match their impression of number size to their impression of the subjective magnitude of a stimulus. In Experiment 1, subjects matched their impression of the stimulus to their impression of the magnitude of the length of a continuously variable line under their control. In Experiment 2, subjects rated perceived sweetness on a vertical 13-point scale with five equally spaced verbal labels. In both experiments, three sets of four sucrose concentrations were employed. In two of these sets, a set of weaker solutions and a set of stronger solutions, concentrations were separated by 0.25 log units. In a third set, which spanned the range of concentrations used in the other two sets (0.87 to 27.36% w/v), solutions were separated by 0.5 log units. An examination ofboth individual and group data showed the matching procedure to be less susceptible to a range bias than the rating procedure. In particular, a single intensity function accommodated data from individual ranges better when the matching procedure was used than when the rating procedure was used. No effect of stimulus spacing was evident in the data from either procedure.  相似文献

This article contributes to the debate in the mental health and legal systems concerning involuntary commitments to mental hospitals. The focus is on issues involving the overrepresentation of Black people among adults committed to U.S. public mental institutions and issues involving the assessment of relevant behavioral functioning in particular. Empirical findings, legal principles and procedures, and methodological limitations are reviewed to identify problems in current practice and relevant evidence bearing on those problems. Special emphasis is placed on the possible explanations for the overrepresentation of Blacks and on dependable assessments of relevant functioning that are needed to justify the state's coercive power to involuntarily confine people, regardless of race. The article concludes with a summary and recommendations for research and practice.  相似文献

This study drew upon the physiological model of stress and desensitization processes to deduce hypotheses linking the intensity of conflict communication and exposure to familial verbal aggression in childhood to experiences of conflict within romantic relationships. One hundred college‐aged students (50 dating couples) participated in a dyadic interaction in which partners discussed a source of conflict in their romantic relationship. Participants reported childhood exposure to familial verbal aggression, third‐party observers rated the intensity of conflict communication, and salivary cortisol indexed physiological stress responses to the conflict interactions. As predicted, results showed a positive association between conflict intensity and cortisol reactivity, and this association was attenuated for individuals who reported higher, rather than lower, levels of childhood exposure to familial verbal aggression.  相似文献
