At the segmental level, the rate of speaking affects the degree of physical undershoot of articulatory targets and the resulting perception. Little is known regarding evidence of these effects at the suprasegmental level, particularly in intonation. In this study, the effect of rate of speaking on fundamental frequency and on perceptual judgments of peak pitch in a rise-fall intonation pattern was investigated. First, speakers produced rise-fall intonations in sentence contexts at slow, normal, and fast speaking rates. Peak fundamental frequencies (F0) of the slow productions were significantly lower than those of the normal or fast productions. The mean normal rate production of the word Miami was used as a model for the target word in a series of subsequent perceptual experiments. Altering the duration of the target word to represent slow, normal, and fast rates of speaking did not affect listener judgment of peak pitch. Finally, the pitch of the target word was measured in a sentence context. No differences between peak pitch in isolation or in sentence context were found. It was concluded that the production and perception of this form of intonation was not subject to the effects of rate that are seen at the segmental level. 相似文献

Response time studies of acquired language disorders are plagued by tremendous variability in patients' response times. In this brief report we demonstrate how variability itself may provide informative data. Lexical decision response times, generated by nine patients, illustrate how within-patient variability may estimate stability in cognitive dynamics. 相似文献

Gender is a dimension of face recognition 总被引:1,自引:0,他引:1

In an experiment, the authors investigated the impact of gender categorization on face recognition. Participants were familiarized with composite androgynous faces labeled with either a woman's first name (Mary) or a man's first name (John). The results indicated that participants more quickly eliminated faces of the opposite gender than faces of the same gender than the face they were looking for. This gender effect did not result from greater similarity between faces of the same gender. Rather, early gender categorization of a face during face recognition appears to speed up the comparison process between the perceptual input and the facial representation. Implications for face recognition models are discussed. 相似文献

Ubiquitous 1/f scaling in human cognition and physiology suggests a mind-body interaction that contradicts commonly held assumptions. The intrinsic dynamics of psychological phenomena are interaction dominant (rather than component dominant), and the origin of purposive behavior lies with a general principle of self-organization (rather than a special neurocognitive mechanism). E.-J. Wagenmakers, S. Farrell, and R. Ratcliff (2005) raised concerns about the kinds of data and analyses that support generic 1/f scaling. This reply is a defense that furthermore questions the model that Wagenmakers and colleagues endorse and their strategy for addressing complexity. 相似文献

Despite widespread use of mental health testimony in cases where violence risk is at issue, relatively little is known about the impact of such information on juror decision-making. This study addressed the effects of testimony based on three types of risk assessment instrument or method (clinical opinion, actuarial assessment, and ratings of psychopathy) to examine whether they would have differential impact on jurors' perceptions of the defendant. In a mock sexually violent predator civil commitment trial, 172 undergraduates were presented a case summary that included prosecution and defense expert testimony related to violence risk based on one of the three methods noted above. Consistent with earlier research, the hypothesis that a defendant described as a "high risk psychopath" by the prosecution would be judged more severely than a defendant judged as "high risk" based on other evaluation procedures was supported, but only among female jurors. Unlike prior studies, little support was found for the hypothesis that clinical opinion testimony would be more influential than actuarially based testimony for either gender. Mechanisms that may underlie the observed gender differences are discussed, as are the potential implications of these findings for civil commitment proceedings. 相似文献

Relatively little is known about the processes in which "successful" malingerers engage to avoid detection. This study summarizes the response strategies used by participants (N = 540) instructed to feign a specific mental disorder while completing various self-report instruments designed to detect faking. Postexperiment questionnaires indicated that those who were able to appear symptomatic while avoiding being detected as feigning (n = 60) were more likely to endorse a lower rate of legitimate symptoms, to avoid overly unusual or bizarre items, and to base their responses on their own personal experiences. 相似文献

The incarceration of mentally ill youth is a serious problem not receiving the same attention as in adults. In this study, we examine the prevalence of psychopathology and level of behavioral symptomatology in incarcerated youth versus youth receiving community mental health services or hospitalization. We randomly recruited youth from middle South Carolina served by a local CMHC (n = 60), youth served by the state adolescent inpatient program (n = 50), and youth in the S.C. Dept. of Juvenile Justice facilities from the same region (n = 75). We used the DISC-PC 2.3 to evaluate DSM-III-R diagnoses and the CBCL and YSR to evaluate behavioral symptomatology. On the DISC, incarcerated youth had significantly higher mean number of diagnoses and symptoms than CMHC youth, but lower numbers than hospitalized youth. Level of caseness (at least one diagnosis) was 86% in hospital youth, 72% in incarcerated youth, and 60% in CMHC youth. The groups differed in CBCL mean total T, internalizing T, and externalizing T scores as well as mean YSR internalizing T scores. Our results indicate the comparability in level of psychopathology in incarcerated and community-treated populations of youth, and the need to develop diversionary programs to prevent the entry of such youth into the juvenile justice system. 相似文献

This study provides a cross-sectional analysis of the relations between group self-identification and adolescent drug use in 3 samples of youth: comprehensive high-school, continuation high-school, and runaway/street youth. Youth identified with discrete groups in all 3 samples, and similar general groups were formed. In most comparisons, a high-risk group showed greater levels of drug use than did other groups. This is the first study to demonstrate that group self-identification (a) is a generalizable construct across different types of adolescent samples, (b) is related to use of drugs other than tobacco, and (c) remains a significant correlate of drug use controlling for its relations with demographic variables and several other psychosocial variables. 相似文献
