Videocassettes have become the dominant medium for pornography. One previous content analysis examined the prevalence of violence in such videos. The Attorney General's Commission on Pornography (1986) has asserted that nonviolent pornography depicting degradation produces harm similar to that from violent pornography. Content analysis of a 10% random sample (n = 50) of the videos displayed in the "adult" section of a video store showed that 13.6% of the scenes in the videos contained violent acts and 18.2% contained degrading acts. 相似文献

This study examined three factors affecting college students' attributions of blame for an AIDS patient's disease: sexual orientation of the patient, mode of HIV transmission, and the sex of the subject. 148 subjects read one of six vignettes describing an hypothetical AIDS patient who was described as either an heterosexual or an homosexual man who contracted HIV through one of three avenues: blood transfusion, sexual contact, or IV drug use. The homosexual AIDS patient was considered more to blame for his illness than the heterosexual AIDS patient, but only when mode of transmission was sexual contact. In addition, mode of HIV transmission was a significant factor in attributions of responsibility, as the patient who contracted HIV through a blood transfusion was rated as less responsible than the patient who contracted HIV through sexual behavior or IV drug use. Women consistently rated the AIDS patient as less responsible than did men. 相似文献

Carroll and Chang have claimed that CANDECOMP applied to symmetric matrices yields equivalent coordinate matrices, as needed for INDSCAL. Although this claim has appeared to be valid for all practical purposes, it has gone without a rigorous mathematical footing. The purpose of the present paper is to clarify CANDECOMP in this respect. It is shown that equivalent coordinate matrices are not granted at global minima when the symmetric matrices are not Gramian, or when these matrices are Gramian but the solution not globally optimal.Part of this research has been supported by The Netherlands Organization for Scientific Research (NWO), PSYCHON-grant (560-267-011). 相似文献

Recently, feminists like Jane Roland-Martin, Elizabeth Young-Bruehl, and others have advocated a conversational metaphor for thinking and rationality, and our image of the rational person. Elizabeth Young-Bruehl refers to thinking as a constant interconnecting of representations of experiences and an extension of how we hear ourselves and others. There are numerous disadvantages to thinking about thinking as a conversation.We think there are difficulties in accepting the current formulation of the conversational metaphor without question. First, there is danger that we will lose important dialectical connections like that between the self and society. Second, the conversational metaphor alone cannot fully express the way conversations are constructed. We will want to take up the notion of narrative as a metaphor for thinking advocated by Susan Bordo, Alasdair MacIntyre, Jerome Bruner, and others, including Mary Belenky and her colleagues.Eventually, we want to champion narrative and the dramatic narrative of culture as a metaphor for thinking that involves such expressions as sights, insights, silences, as well as sounds, moments of mood and poetic moments. The dramatic narrative provides the structural possibilities needed to criticize certain kinds of conversations, in order to talk about the relations of public and private, self and society and most importantly, about the drama of our lives within and without.The dramatic narrative for thinking helps dispel the dangerous dualisms of mind and body that not even conversation or narration alone can banish, and allows us to frame questions about education that do not require us to separate mind from body. The dramatic narrative metaphor for thinking lets us show who we are, act out what we think, and reconstruct rationality to reflect what many women, and some men, do. 相似文献

Treiman (1983) and others have argued that spoken syllables are best characterized not as linear strings of phonemes, but as hierarchically organized units consisting of an onset (initial consonant or consonant cluster) and a rime (the vowel and any following consonants) and that the rime is further divided into a peak or nucleus (the vowel) and a coda (the final consonants). It has also been argued that the sonority (or vowel-likeness) of the consonant closest to the peak, which is a function of its phonetic class, may have an effect on the strength of boundaries determined by the hierarchical division of the syllable (e.g., Treiman, 1984). We examined the evidence for syllable-internal structure and for sonority in two experiments that employed visually presented stimuli and lexical decision, naming, and reading tasks. Our results provide support for the breakdown of the rime into a peak and a coda and for an effect of the sonority of the postvocalic consonant on that break. This pattern occurred only in our lexical decision tasks, so the effect is assumed to be postlexical. We did not find an effect of the onset-rime boundary, perhaps because of an unanticipated effect of word frequency. Our results are discussed in terms of phonological coding in short-term memory. 相似文献

Conducted a community survey in the Fall of 1984 in a sample of high unemployment blue-collar census tracts in southeastern Michigan. Results of earlier analyses using these data showed that involuntarily unemployed workers had significantly elevated levels of depression, anxiety, somatization, and self-reported physical illness relative to a stably employed comparison group (Kessler, House, & Turner, 1987). Results presented in this paper document that this relationship is modified by social support (as measured by social integration and the availability of a confidant), self-concept, and various coping processes. Further analyses allowed us to determine the way in which these modifiers operate. The modifying effects of social support and coping operate primarily by buffering the impact of unemployment-related financial strain on the health outcomes. Self-concept operates primarily by attenuating vulnerability to other stressful life events. The implications of these results for the design and implementation of preventive interventions are discussed. 相似文献

The developmental course of rhythmic motor behavior was followed longitudinally for three groups of preambulatory children — normally developing, Down syndrome, and those with profound motor impairment. The groups differed in chronological age but were comparable with respect to motor age. The motor impaired subjects displayed significantly less rhythmic motor behavior than the nondisabled and Down syndrome groups. In comparing particular subtypes of rhythmic motor behavior, differences were found in both the average number of bouts and duration of subtypes among the groups. Longitudinal analyses of the data over the entire observation period revealed that the rhythmic motor behavior of the children with Down syndrome was more similar to that exhibited by the nondisabled children than was the rhythmic motor behavior of the children with motor impairment. However, there was considerable variability among the groups in several particular subtypes.This research was supported by grants from the National Institute of Child Health and Human Development (HD 17650 and HD 07226).The authors acknowledge the assistance of Robert E. Arendt, Grant Youngquist, Michael Hohn, and Charles Lowitzer in obtaining the observational data and thank the families of the subjects for their enthusiasm and dedication to the project.This study was presented at the 23rd Annual Gatlinburg Conference on Research and Theory in Mental Retardation and Developmental Disabilities, April 21, 1990. 相似文献

The semantic priming effect can be reduced or eliminated depending on how the prime word is processed. The experiments reported here investigate this prime task effect. Two experiments used identity and semantic priming tasks to determine whether the prime word is encoded at a lexical level under letter-search conditions. When the prime task was naming, both identity and semantic priming occurred; however, when a letter-search task was performed on the prime word, only identity priming occurred, thus supporting the argument that the search task affects activation of semantic associates rather than lexical access of the prime word. Another experiment demonstrated that this identity priming was the result of lexical processes rather than of letter-by-letter priming. A cross-modal priming technique demonstrated that the letter-search prime task does not actively suppress activation of semantic associates. The implications of these results for automaticity and for proposed mechanisms of priming are discussed. 相似文献

The purpose of this study was to isolate possible sources of learning ability differences in distinctive encoding of item-specific and relational information. Two mechanisms postulated as underlying ability group differences were attentional capacity (as inferred from the magnitude and direction of correlations between primary and secondary recall) and resource monitoring strategies (as reflected in measures of selective attention and laterality). In Experiment 1, learning disabled and nondisabled childrens' word recall was compared on dichotic listening recall tasks that included nonorienting instructions, and orienting instructions that directed children's attention toward semantic, phonemic, or structural word features. Disabled children showed lower recall and more diffuse selective attention to word features than nondisabled children. Reciprocity (negative correlations) between targeted and background words within and between ability groups was comparable, except when targeted word features were phonemically organized. Experiment 2 indicated that disabled childrens' cued recall was inferior to that of nondisabled children, even though both ability groups produced comparable symmetrical recall patterns related to ear presentations. Taken together, the results suggest that the locus of disabled childrens' distinctive encoding deficiencies is related to resource monitoring strategies during interhemispheric processing. 相似文献
