In this study, we attempted to determine whether phonetic disintegration of speech in Broca's aphasia affects the spectral characteristics of speech sounds as has been shown for the temporal characteristics of speech. To this end, we investigated the production of place of articulation in Broca's aphasics. Acoustic analysis of the spectral characteristics for stop consonants were conducted. Results indicated that the static aspects of speech production were preserved, as Broca's aphasics seemed to be able to reach the articulatory configuration for the appropriate place of articulation. However, the dynamic aspects of speech production seemed to be impaired, as their productions reflected problems with the source characteristics of speech sounds and with the integration of articulatory movements in the vocal tract. Listener perceptions of the aphasics' productions were compared with acoustic analyses for these same productions. The two measures were related; that is, the spectral characteristics of the utterances provided salient cues for place of articulation perception. An analysis of the occurrences of errors along the dimensions of voicing and place showed that aphasics rarely produce utterances containing both voice and place substitutions. 相似文献

Two experiments examined the influence of postconditioning treatments of contextual cues on instrumental responding acquired with a signaled delay of reinforcement schedule. In Experiment 1, mere exposure to the conditioning context after instrumental training resulted in an attenuated response rate during an extinction test. In the second experiment, responding was decreased by exposure to the contextual cues or sessions in which signaled noncontingent reinforcements occurred. The greatest response decrement, however, occurred following unsignaled noncontingent food presentations. The results are discussed with respect to the different roles of contextual cues on operant responding. 相似文献

This experiment examined changes in anxiety and differences in aggression for high and low assertive women when different degrees of conflict were encountered. As predicted, low assertive women were intially more uneasy or anxious than high assertive women when they were placed in a conflictual situation. When the level of actual conflict was low, the level of anxiety of low assertive women decreased. However, when the actual level of conflict was high the anxiety level of low assertive women remained unchanged. These results were taken as support for the fear of conflict hypothesis which predicted that the reduction in anxiety for low assertive persons is contingent upon whether or not the anticipated conflict is actually encountered. The results also indicated that high assertive women were not significantly more aggressive than low assertive women. This finding provided support for Galassi's position that assertiveness and aggression are distinct concepts. 相似文献

Over the last few years, there has been increased interest in the addictive potential of the Internet. The current study was an attempt to replicate common findings in the literature and provide more evidence for the existence of Internet addiction among students--a population considered to be especially vulnerable. A total of 371 British students responded to the questionnaire, which included the Pathological Internet Use (PIU) scale, the General Health Questionnaire (GHQ-12), a self-esteem scale, and two measures of disinhibition. Results showed that 18.3% of the sample were considered to be pathological Internet users, whose excessive use of the Internet was causing academic, social, and interpersonal problems. Other results showed that pathological Internet users had lower self-esteem and were more socially disinhibited. However, there was no significant difference in GHQ scores. These results are discussed in relation to the methodological shortcomings of research in the area as a whole. 相似文献

Liberal theories of social justicefocus predominantly on the national, ratherthan international, level, and where they doaddress
international concerns they insist thatprinciples of justice at the national levelhave priority over principles at theinternational
level. We question the coherenceof this arrangement, given liberal theory'scommitment to moral equality of persons as suchrather
than to that of particular sets of persons. What isat issue is whether liberal theory can providea coherent basis for international
justice atall. If it is to do so, we suggest that it mustbe prepared to theorise beyond the nationstate, and to take a historical
perspectivewhich takes into account the ways in whichcolonial power and exploitation have given riseto the problems of international
justice weface today.

The current study examined the effects of a brief mindfulness induction on overselectivity. Participants were randomly assigned to a mindfulness, unfocused attention (relaxation), or no‐intervention group. Participants experienced their designated intervention for 10 min, and they underwent simultaneous discrimination training (AB+ CD?) followed by an extinction test (AvC, AvD, BvC, and BvD). Levels of mindfulness were measured by the Toronto Mindfulness Scale, and participants were asked about their previous experience with mediation and mindfulness practice. Mindfulness reduced overselectivity, and previous levels of mindfulness experience identified by a single question moderated this effect, with mindful‐experienced participants showing less overselectivity. Both findings have some practical utility in the ongoing investigation of the possible use of mindfulness in medical settings. 相似文献

Deviations from otherwise reliable patterns of responding in human performance on schedules of reinforcement could be associated with personality characteristics, such as psychometrically-measured schizotypy. The present study examined differences between high and low scorers on four schizotypy subscales (unusual experiences, cognitive disorganisation, introvertive anhedonia and impulsive non-conformity) on a random-ratio (RR) and random-interval (RI) schedule of reinforcement. Results showed a higher rate of responding on the RR than RI schedule, consistent with the differences in performance normally observed between these schedules. However, these differences were dependant on whether or not participants scored high or low on the schizotypy subscales, as well as the specific schedule parameters between the schedules. Specifically, high scorers on the unusual experiences (UE) subscale of the O-LIFE(B) were the only group in Experiment 1 not to show a difference in schedule performance, suggesting high scores on this subscale are linked to altered RR and RI performance. Experiment 2 explored this finding further using different schedule parameters, and confirmed that high scorers in UE did not differ in response rates between the two schedules. 相似文献
