A formal set of axioms is presented for the method of successive intervals, and directly testable consequences of the scaling assumptions are derived. Then by a systematic modification of basic axioms the scaling model is generalized to non-normal stimulus distributions of both specified and unspecified form. 相似文献

The present study was undertaken to determine whether pacing and masking would facilitate improved speech initiation times (SITs) both for stutterers and for nonstutterers. All subjects were tested in control, pacing, and masking conditions. The results showed that both stutterers and nonstutterers (1) improved their SITs during the pacing condition as compared with the control condition (p = 0.01), (2) had slower SITs in the masking condition as compared with the control condition (p = 0.05), and (3) had faster SITs during the pacing as compared with the masking condition (p = 0.01). The SIT between-group findings demonstrated that stutterers were slower than nonstutterers across all SIT conditions (p = 0.08). The discussion of these results centers on the facilatory nature of novel stimulation in modifying speech-system functioning. 相似文献

Five adult humans palpated silicone breast models in a lump-detection task. The effects on detection of several lump and model characteristics were studied in three phases, using both discrete trial (restricted search procedure) and “free response” (free search procedure) psychophysical methods. Size and depth of fixed steel lumps were varied in Phase 1. Depth and hardness of uniformly sized, fixed lumps were varied in Phase 2. The presence and depth of simulated breast nodularity were also studied in Phases 1 and 2. In Phase 3, all breast models were uniformly nodular and lumps varied along dimensions of size, depth, hardness, and fixation. In Phase 1, lump detection was greatest with maximum lump size and minimum depth within the model. Neither lump hardness nor depth differentially influenced detection of the fixed lumps in Phase 2. When breast lumps were mobile, in Phase 3, size and hardness were major stimulus dimensions determining detection. These results suggest physical parameters for realistic breast models and lumps to be used in training effective breast self-examination and breast lump detection. 相似文献

An evaluation was made of reality orientation therapy utilizing 14 male patients with dementias of various types. The therapy is designed to improve memory and reduce confusion in elderly and demented individuals. Utilizing a group comparison with crossover design, it was found that the patients improved significantly over sessions on orientation items actually taught during those sessions. However, no significant improvement was found on a series of generalization items consisting of orientation-related questions that were not asked during sessions. Furthermore, there was no generalization to ward activities. It was noted that individual responses to the treatment were quite varied, and so three cases reflecting highly different responses are presented.Indebtedness is expressed to the Veterans Administration for support of this research. 相似文献

Information relevant to a decision is often available from several sources, such as different sensory modalities or different spatial locations. Processing or utilization of such information is often selective in that some sources seem to have more influence on a decision or response than others. Many different theoretical mechanisms have been proposed to account for such selective (i.e., attentional) aspects of human information processing. This paper considers theoretical mechanisms which operate to integrate separate sources of information in order to make a binary decision. In particular, these mechanisms are studied in simple visual and auditory detection tasks as well as a Bayesian decision problem. Data from these experiments reject the idea that one integrates the relevant information from several sources prior to making a decision. Rather, one seems to form separate decisions about the information from each source and then integrate these decisions in order to select a response. 相似文献

Past research on adolescent attainment has virtually ignored the interactional aspects through which children learn attainment values. Using a simulated career game, parent-child interaction (father, mother, and adolescent son or daughter) was coded to assess its impact on the child's attainment value. Encouragement patterns, parental opportunity awareness, and family affect were examined. Results revealed differences in these family interaction variables as sources and determinants of adolescent attainment value, depending upon sex of child. The variables were able to account for considerably more of the variation in sons' attainment value than daughters'.This study was made possible by grants from the National Institute of Mental Health (#15521-04), the Midwest Universities Consortium for International Activities (MUCIA) (*G-75), and the Minnesota Center for Comparative Studies in Technological Development and Social Change (funds provided by the Ford Foundation) (#26301), principal investigator, Irving Tallman. The author would like to acknowledge the helpful comments made by Viktor Gecas, Jeylan Mortimer, Irving Tallman, and especially Milton Rokeach on an earlier draft of this article. 相似文献

Speech rate can be reduced by prolonging the duration of phonetic units, by pausing between words, or through a combination of these approaches. Child and adult normally fluent speakers and stutterers were tested in basal and modified speaking rate conditions. Subjects' utterances in both conditions were converted to spectrographic displays so that measures of phonetic and pause durations could be made. Comparisons of these measures across conditions revealed that all four groups of subjects spontaneously extended pause and phonetic durations, the former more than the latter, when instructed to voluntarily reduce speech rate. 相似文献

This study was designed to explore the speech timing skills of normally fluent and stuttering children and adults producing two sentences, ten consecutive times at basal and modified speaking rates. Spectrographic displays of subjects' utterances in both conditions were made in order to obtain consonant, vowel, pause, and utterance duration measures. Results showed that (1) the two groups of children produced speech durational values similar to those of the two adult groups and (3) there were no consistent between- and within-group differences in the basal and modified rate conditions. Findings are discussed in terms of methodological and sampling differences that exist between the present study and past research on stutterers' speech production abilities. 相似文献

Thispaper is an attempt to describe and examine the role of the counsellor in relation to anorexia nervosa. The condition is analysed in terms of its social and psychological factors. The need for control and self-mastery is put forward as a dominating characteristic. The role of refeeding in anorexia is discussed, with the suggestion that the attitudes of anorexies and their doctors need to be understood as a whole. Finally, the counselling possibilities are suggested, and the position of the counsellor vis-à-vis the refeeders is discussed. 相似文献

The hypothesis was tested that pre-menstrual and post-menstrua I increases in sexual activity are due to anticipation of deprivation and rebound following deprivation (Ford & Beach, 1951). Thirty-five married women completed daily questionnaires about their sexual activity for at least two menstrual cycles. Evidence supported the hypothesis that the post-menstrual peak in intercourse is a rebound phenomenon. There was less evidence to support the hypothesis that a pre-menstrual rise represents anticipation of deprivation. In addition, there was a tendency to increase autosexual activity during periods of sexual abstention, which may represent a compensation phenomenon. 相似文献
