Using a multi-trial, free-recall paradigm (Rey Auditory-Verbal Learning Test; Lezak, 1983), the acquisition and retention by learning disabled (LD) young adults with a Halstead Impairment Index less than or equal to 0.3 (low LD) or greater than or equal to 0.4 (high LD) was compared with that of nondisabled and head-injured (HI) young adults. Significant group differences, particularly during the last three acquisition trials, confirmed the effectiveness of this method in revealing subtle learning and retention deficits. Analyses of Trial 1 recall showed group differences in the prerecency but not the recency portion of the serial position curve, thus implicating long-term but not short-term memory differences between the groups. Analyses of pair frequency (Sternberg & Tulving, 1977) data showed that the three clinical groups had difficulty organizing the to-be-learned material for effective retrieval. Following an interpolated task, retention was poorer for the clinical groups than for the nondisabled and varied inversely with the degree of neuropsychological impairment. Finally, during retention, the nondisabled and low LD groups retained and used the list organization established during acquisition whereas the high LD and HI groups did not. 相似文献

Head-related transfer functions for differently centered narrow noise bands were obtained on 6 subjects. Derived from these measurements were covert peak areas (CPAs), defined as the spatial constellation of loudspeakers that generates maximal sound pressure at the entrance of the ear canal for specific bands of frequency. On the basis of previous data, we proposed that different frequency bands served as important spectral cues for monaural localization of sounds from different loci and that location judgments were directed toward the CPAs associated with the different bands. In the first study, the stimuli were bandpass filtered so that they contained only those frequencies whose associated CPAs occupied either the monaural listener’s “upper” or “lower” spatial regions. Loudspeakers, separated by 15°, were stationed in the left hemifield, ranging from 0° to 180° azimuth and ?45° to 60° elevation. Subjects reported the loudspeaker from which the sound appeared to originate. Judgments of the sound’s elevation were in general accord with the CPAs associated with the different frequency segments. In the second study, monaural localization tests were administered in which different 2.0-kHz-wide frequency bands linked with specific CPAs were notch filtered from a 3.5-kHz highpass noise band. For the control condition, the highpass noise was unfiltered. The data demonstrated that filtering a frequency segment linked with specific CPAs resulted in significantly fewer location responses directed toward that particular spatial region. These results demonstrate in greater detail the relation between the directional filtering properties of the pinna and monaural localization of sound. 相似文献

Co-occurrent use of cigarettes, alcohol, and coffee in healthy, community-living men and women 总被引:5,自引:0,他引:5

Previous studies have examined intra-individual aggregation in the use of cigarettes, alcohol, and coffee by examining the co-occurrent use of any pair of these three substances. A recent literature review failed to find a single investigation that studied use of all three in the same sample. In the present study, co-occurrent use of all three of these substances was examined in crossvalidated subsamples of 226 male and 245 female healthy, community-living, middle-class Americans. A log-linear analysis was used to compare the proportion of smokers, ex-smokers, and nonsmokers categorized as users of more or less amounts of coffee and alcohol. Although most of the intercorrelations were not strong, the results indicate that for both sexes, smokers and ex-smokers were more likely than nonsmokers to drink greater amounts of alcohol and coffee. Furthermore, for smokers, ex-smokers, and nonsmokers, a majority of individuals who reported drinking more alcohol also reported drinking more coffee. Interestingly, the coffee and alcohol consumption levels of ex-smokers resembled those of smokers more than those of nonsmokers. Also, ex-smokers reported drinking more wine and decaffeinated coffee than either smokers or nonsmokers. Finally, the number of cigarettes smoked per day (daily quantity) was positively related to total alcohol and coffee consumption in men, but not in women. Further studies are recommended to examine the role of individual differences in the development, maintenance, and modification of these three appetitive habits and their co-occurrence. 相似文献

In our commentary, we propose that the ORE can be viewed as a form of perceptual expertise. Like experts, we recognize own-race faces at the subordinate level as individuals and novices when recognize other-race faces at the basic level of race. Applying a perceptual expertise account, we explain the ORE in terms of its cognitive, neural, and motivational factors. We suggest that by creating a culture of “other-race” expertise, improvements in other-race face recognition can be achieved. 相似文献

Probing against the vaginal cervix (CP) suppresses responses to noxious stimulation in rats. The first experiment rules out the possibility that this effect is due to CP-induced immobilization. All rats first learned to press a panel, thus terminating noxious skin shock. Then they either received CP (experimentals) or did not (controls) when they pressed the panel during skin shock that was inescapable. The controls soon showed extinction of the panel-press response, whereas the experimentals continued pressing the panel and obtaining CP, for significantly more trials. The rats thus performed an operant response for CP at a time before CP could have blocked their movement. The second experiment argues against the possiblity that CP exerts its effect by "distracting" the rats from the skin shock. The rats received inescapable skin shock which continued for 7 sec after each panel-press response. During this shock one group received CP, and another received perineal probing ("distraction" control). The panel-press latency was significantly shorter in the CP group than in the perineal group. Latency in a control group, in which shock was terminated as soon as the rats pressed the panel, did not differ significantly from the CP group. Latency in another control group, in which the shock persisted for 7 sec after the rats pressed the panel with no probing being applied, was not significantly different from that of the perineal-probing group but was significantly longer than latency in the CP group. Thus the present studies suggest that CP is indeed analgesic and that this effect of CP is mediated by neither movement inhibition nor distraction. 相似文献

ABSTRACT This article uses discourse analysis to explore the intersection of spiritual warfare demonology and Christian nationalism among Trump-supporting neo-charismatic evangelicals. Analysing public materials produced during and after the 2016 US presidential campaign, it demonstrates how demonologies operate discursively to categorise, comprehend, and contest understandings of American identity and destiny. Situating spiritual warfare demonology in relation to narratives of ‘post-truth politics’ as the destabilisation of neoliberal consensus reality, the article explores how charismatic evangelicals position Trump’s election as a divine assault on a demoniac status quo, epitomised in the conspiratorial figure of the ‘Deep State.’ Examining demonologies of the ‘state’ and ‘border’ as joint arenas of epistemic and societal contestation, the article shows how spiritual warfare discourses seek to (re)define sociocultural notions of truth and falsity and thereby (de)legitimise specific gendered, sexualised, and racialised forms of being and belonging. 相似文献
