This article reports the results of a content analysis of sexual rhetoric in editorial photographs (N=994) in 2001 issues of Maxim and Stuff magazines. Goffman’s (1979) classifications of gender in advertisements were used to examine how this new generation of “lad” magazines uses images to provide readers with cues about sexuality and sexual practice. The findings reveal that both magazines construct sexuality in similar ways. However, as expected, the overall message about sexuality in the photos is different for men than for women. Women are more likely than men to be portrayed as sex objects, such as the common practice of photographing them in contorting or demeaning positions. Both magazines also depict white people as sexier than other races and assume heterosexuality.  相似文献

We tested 186 children ranging in age from 6 years, 10 months to 13 years, 7 months; 174 suffered either physical and/or sexual abuse, and 12 were nonabused children. Abused subjects were grouped in four different ways. The primary grouping was based on whether subjects satisfied the DSM III-R criteria for posttraumatic stress disorder (PTSD). Secondary groupings were based upon the three symptom clusters used to make the PTSD diagnosis (arousal, avaidance, and reexperiencing). In each of these groupings three separate subgroups were formed with approximately 25 percent in the high and low symptom count subgroups and the remaining 50 percent in the middle symptom count subgroup. Subjects listened to four different intensity levels (65, 80, 95, and 102 dB) of a 1 KHz tone, pseudo-randomly ordered, while event-related brain potentials (ERPs) were recorded. Two separate blocks were used, one with short intervals (4±1 sec) between tones and the other with longer intervals (17±2 sec). PTSD subjects presented a greater P2-N2 ERP intensity gradient (i.e., a larger increase in the P2-N2 ERP component as tone intensity increased) than did abused subjects without PTSD. Abused subjects with the highest number of reexperiencing symptoms showed a similar P2-N2 augmenting effect when compared to those with the lowest number of reexperiencing symptoms. Subjects with the highest number of arousal symptoms showed a shallower intensity gradient for the N1-P2 ERP component than did those with fewer arousal symptoms. The results are discussed in relation to previous results reported on adults with PTSD and in terms of CNS processing of stimulus intensity information.  相似文献

The mental health histories of the 448 children 15 and 16 years of age who were admitted to state-operated children's psychiatric inpatient services in New York during 1982 were reviewed for the 11 year period through April 1993, Thirty-three percent were served as adults (after age 18) in the state-operated adult civil mental health system; 42% of these individuals were still receiving services at the end of the period. 113 of the 146 individuals served as adults were served only in the civil system. Thirteen percent of the cohort received some of their mental health services as adults in the state-operated adult forensic mental health system due to criminal law involvement. This includes nine percent who received mental health services while they were inmates in state prisons. Twenty four of the 57 forensic clients received services as adults only in the forensic system. Diagnostic, demographic, and service history characteristics of the groups were compared to foster an early understanding of policy and programmatic issues related to movement from the child mental health system to the adult system. Baseline (1982) information was used to identify predictors of later service utilization.  相似文献

Two studies are reported in which the effects of supervisor observations of teachers' performance rate and accuracy on both teachers' and severely handicapped students' behaviors were compared with baseline supervisor observations that did not specify rate and accuracy feedback. The latter observation procedure (nonspecific feedback) was more typical of the existing practices of school supervisors. The dependent variables for the teachers were rate and accuracy of teacher behaviors to student responses in individualized instructional settings involving discrete trials or task-analysis steps. The dependent variables for students were the rates of correct and incorrect responding to teacher presentations during the supervisor observation periods. Both studies used a multiple baseline design. The results of Study 1 showed that there were educationally significant changes in teacher and, in turn, student performance as a result of the use of the rate and accuracy procedure. The results of Study 2 replicated those of Study 1 while correcting limitations of Study 1. This latter study also demonstrated that the observation effects of the procedure generalized to teacher performance throughout the day. The results are discussed in terms of the efficiency and cost effectiveness of the procedure to train, monitor, and reinforce teacher effectiveness.  相似文献

Clinically referred children, diagnosed as having learning or attention disorders, with or without hyperactivity, were found to vary widely on a measure of nervous system sensitivity recommended by the Pavlovian investigator Vasilev. That is, the children were contrasted on their mean press and release reaction times (RTs) to four tones, ranging from soft (55 db) to very loud (100 db), with the expectation that some would be able to maintain a parallel separation of press and release RT gradients across all intensity levels (strength), whereas others would show convergence or overlap of the gradients at higher intensities (weakness). Contrary to expectation, girls did not have weaker or more sensitive nervous systems than boys, although the girls rated themselves as less tolerant of intense stimuli. Significantly more of the children diagnosed as hyperactive had weaker nervous systems. The boys also participated in a blind crossover study contrasting placebo and methylphenidate effects; the prescribing physician, who was not informed of the child’s nervous system classification, adjusted the dosage levels so that subjects with weaker nervous systems were titrated at higher dosage levels than those with stronger nervous systems. Gray (1964) suggested an explanation of this paradox, i.e., that the weak nervous system requires a more intense stimulus than the strong to reach the threshold of concentration (or focused attention), whereas for other thresholds the strong requires a more intense stimulus than the weak. Gray’s theory was further supported by the finding that children typed as weak (unmedicated) did not show as great facilitation in RT with reward (moderate stimulus) as did those typed as strong.  相似文献

Heart rate and skin conductance measures, recorded during a visual search task, were compared for hyperactive, reading-disabled, hyperactive reading-disabled, and control elementary school boys. As shown in past work, basal autonomic levels did not statistically differentiate groups. In all groups, heart rate levels increased with task complexity, but more so on reward than on nonreward trials. In the intertriai interval, heart rate decelerated consistently when subjects were anticipating stimuli associated with reward, but when reward was uncertain, heart rate accelerated slightly or stayed the same. Control subjects exhibited anticipatory heart rate deceleration more consistently than did clinical subjects, especially the solely hyperactive ones. Skin conductance levels first decreased, then rose as task complexity increased, but the groups did not differ on this measure. A conditioning model is outlined to explain directional changes in heart rate.  相似文献
