This study investigated whether being charged with a child pornography offense is a valid diagnostic indicator of pedophilia, as represented by an index of phallometrically assessed sexual arousal to children. The sample of 685 male patients was referred between 1995 and 2004 for a sexological assessment of their sexual interests and behavior. As a group, child pornography offenders showed greater sexual arousal to children than to adults and differed from groups of sex offenders against children, sex offenders against adults, and general sexology patients. The results suggest child pornography offending is a stronger diagnostic indicator of pedophilia than is sexually offending against child victims. Theoretical and clinical implications are discussed. 相似文献

The Fear Survey Schedule-III (FSS-III) was administered to a total of 5491 students in Australia, East Germany, Great Britain, Greece, Guatemala, Hungary, Italy, Japan, Spain, Sweden, and Venezuela, and submitted to the multiple group method of confirmatory analysis (MGM) in order to determine the cross-national dimensional constancy of the five-factor model of self-assessed fears originally established in Dutch, British, and Canadian samples. The model comprises fears of bodily injury-illness-death, agoraphobic fears, social fears, fears of sexual and aggressive scenes, and harmless animals fears. Close correspondence between the factors was demonstrated across national samples. In each country, the corresponding scales were internally consistent, were intercorrelated at magnitudes comparable to those yielded in the original samples, and yielded (in 93% of the total number of 55 comparisons) sex differences in line with the usual finding (higher scores for females). In each country, the relatively largest sex differences were obtained on harmless animals fears. The organization of self-assessed fears is sufficiently similar across nations to warrant the use of the same weight matrix (scoring key) for the FSS-III in the different countries and to make cross-national comparisons feasible. This opens the way to further studies that attempt to predict (on an a priori basis) cross-national variations in fear levels with dimensions of national cultures. 相似文献

What roles do syntax and semantics have in the grammar of a language? What are the consequences of these roles for syntactic structure, and why does it matter? We sketch the Simpler Syntax Hypothesis, which holds that much of the explanatory role attributed to syntax in contemporary linguistics is properly the responsibility of semantics. This rebalancing permits broader coverage of empirical linguistic phenomena and promises a tighter integration of linguistic theory into the cognitive scientific enterprise. We suggest that the general perspective of the Simpler Syntax Hypothesis is well suited to approaching language processing and language evolution, and to computational applications that draw upon linguistic insights. 相似文献

The faculty of language: what's special about it? 总被引:15,自引:0,他引:15
We examine the question of which aspects of language are uniquely human and uniquely linguistic in light of recent suggestions by Hauser, Chomsky, and Fitch that the only such aspect is syntactic recursion, the rest of language being either specific to humans but not to language (e.g. words and concepts) or not specific to humans (e.g. speech perception). We find the hypothesis problematic. It ignores the many aspects of grammar that are not recursive, such as phonology, morphology, case, agreement, and many properties of words. It is inconsistent with the anatomy and neural control of the human vocal tract. And it is weakened by experiments suggesting that speech perception cannot be reduced to primate audition, that word learning cannot be reduced to fact learning, and that at least one gene involved in speech and language was evolutionarily selected in the human lineage but is not specific to recursion. The recursion-only claim, we suggest, is motivated by Chomsky's recent approach to syntax, the Minimalist Program, which de-emphasizes the same aspects of language. The approach, however, is sufficiently problematic that it cannot be used to support claims about evolution. We contest related arguments that language is not an adaptation, namely that it is "perfect," non-redundant, unusable in any partial form, and badly designed for communication. The hypothesis that language is a complex adaptation for communication which evolved piecemeal avoids all these problems. 相似文献

This study examined the convergent and discriminant validity of the Wechsler Abbreviated Scale of Intelligence and the Kaufman Brief Intelligence Test for 85 psychiatric inpatients. The correlation between the WASI Full Scale and K-BIT Composite IQ scores was significant (r = .89, p < .001). Multitrait-multimethod analysis of the subtest scores showed that the K-BIT had higher internal consistency for its two subtests but, therefore, less differentiation of cognitive functioning than the brief Wechsler scale, as would be expected due to the larger number and diversity of the latter subtests. Correlations among the Wechsler scale subtests were lower than among those for the K-BIT, so the former may tap different cognitive functions and yield more clinically useful information than the latter. This brief Wechsler scale appears to be a valid screening measure of verbal, performance. and general intellectual ability for use with an inpatient psychiatric population when considerations of the setting or patient preclude administration of a longer measure of intellectual ability. 相似文献

Eyewitness memory is vulnerable to information encountered prior to a lineup. Young (18-30 years) and older (60-80 years) witnesses viewed a crime video. Some witnesses were then exposed to mugshots of innocent suspects that included a critical foil. After a 48-h delay, all the witnesses took part in a target-absent lineup that included the critical foil and five new foils. Witnesses who picked one of the mugshots as the likely perpetrator showed inflated rates of choosing the critical foil from the lineup. Context reinstatement instructions did not reduce choices of innocent foils following mugshot exposure. Despite age-related increases in false choosing, age did not qualify other effects. The results are discussed in terms of commitment, source memory, and gist-based processing. 相似文献

Self-esteem scales tend to represent conditional perceptions of self-esteem. The Worth Index has been previously validated as an effective measure for identifying both conditional and unconditional perceptions of worth. We administered the Worth Index to 1,161 college-aged students at Brigham Young University to assess their current perceptions of unconditional and conditional worth. Both men and women agreed more strongly with items involving unconditional worth than conditional worth. A negative correlation was found between ratings of unconditional and conditional worth. Women had lower unconditional worth scores than men, which was related to being more likely to wish they were someone else, desire to have a better body, and to being concerned about weight. Agreement with two overview measures of self-esteem involving a "good" sense of self and stability of self-esteem was positively associated with agreement on statements about unconditional worth. This research shows the importance of incorporating unconditional worth into self-esteem measures. 相似文献

It has been argued that greater intra-category structural similarity for living things, and the subsequent "visual crowding," makes them more difficult to recognize and name for neurologically damaged individuals and normal subjects (Humphreys et al., 1988). Nevertheless, the precise meaning and quantification of structural similarity remains unclear, as does the rationale for why it necessarily should be greater for living things. We derived a new measure of visual overlap from the Snodgrass and Vanderwart corpus of line drawings: the degree of pixel overlap within subcategories (Euclidean distance: ED). Contrary to existing notions of visual crowding and extant measures of contour overlap, within-category ED indicated less within-category visual overlap for living things. Furthermore, musical instruments clustered with living things (having low overlap), while body parts clustered with nonliving things (having high overlap). These counter-intuitive findings accord with patient data and thus, provide evidence for the psychological reality and utility of ED. 相似文献

Two-action tests of imitation compare groups that observe topographically different responses to a common manipulandum. The
general aim of the two experiments reported here was to find a demonstrator-consistent responding effect in a procedure that
could be elaborated to investigate aspects of what was learned about the demonstrated lever response. Experiment 1 was a pilot
study with rats of a variant of the two-action method of investigating social learning about observed responses. Groups of
observer rats (Rattus norvegicus) saw a demonstrator push a lever up or down for a food reward. When these observers were subsequently given access to the
lever and rewarded for responses in both directions, their directional preferences were compared with two 'screen control'
groups that were unable to see their demonstrators' behaviour. Demonstrator-consistent responding was found to be restricted
to observers that were able to see demonstrator performance, suggesting that scent cues alone were insufficient to cue a preference
for the demonstrators' response direction and thereby that the rats learned by observation about body movements (imitation)
or lever movement (emulation). Experiment 2 assessed responding on two levers, one that had been manipulated by the demonstrator,
and a second, transposed lever positioned some distance away. Demonstrator-consistent responding was abolished when actions
were observed and performed in different parts of the apparatus, suggesting that observed movement was encoded allocentrically
with respect to the apparatus rather than egocentrically with respect to the actor's body. With particular reference to the
influence of scent cues, the results are discussed in relation to the strengths and weaknesses of this and other varieties
of the two-action procedure as tests of imitation in animals and human infants.
