Ear of input as a determinant of pitch-memory interference 总被引:3,自引:0,他引:3
Howard J. Kallman Patricia A. Cameron Jason W. Beckstead Eileen Joyce 《Memory & cognition》1987,15(5):454-460
Six experiments to evaluate the effect of presentation ear on pitch-memory interference were conducted using undergraduates as listeners. The task was to compare the pitch of two tones that were separated by an interval that included eight interpolated tones; the interpolated tones were presented either ipsilaterally or contralaterally to the presentation ear of the comparison tones. When the ear of interpolated-tone presentations was blocked, and therefore predictable, ipsilateral interference was greater than contralateral. In contrast, when the interpolated-tone presentation ear was varied randomly from trial to trial, ipsilateral and contralateral interferences were equivalent. These results are analogous to results found in previously reported auditory backward recognition masking (ABRM) experiments and suggest that the ABRM effect may be due, in part, to pitch-memory interference. Implications for theories of auditory processing and memory are discussed. 相似文献

Four experiments investigated interference in 5-year-olds' learning sets. Experiment 1 manipulated intertrial and interproblem intervals, showing that increased intertrial intervals retarded performance. Long interproblem intervals interacted with short intertrial intervals to produce performance facilitation. Experiment 2 investigated interpolations within problems with either similar or dissimilar stimulus presentations. Similar stimuli caused greater performance decrements than dissimilar. Experiment 3 hypothesized that the within-subjects design of Experiment 1 masked interproblem interval effects. Testing between-subjects established that increased interproblem delays facilitate performance. In Experiment 4 interproblem delays were further tested in a series of shifts within and between dimensions. Increased delays more greatly benefited shifts within dimensions. It is concluded that intertrial and interproblem intervals affect learning set performance differentially. Intertrial delays result in performance deterioration due in part to interference. Interproblem delays facilitate performance at least in part by providing the opportunity for suppression of proactive interference, and perhaps in part by providing the opportunity for constructive cognitive processing. 相似文献

Seventy-five children of five different age groups (ranging from 13–18 to 37–42 months of age) were tested using various nonverbal indices for (a) their ability to respond to shadowed information about objects other than themselves, (b) their ability to manipulate their own shadow, and (c) their ability to recognize their own shadow as evidenced by the explicit use of shadowed information about themselves to respond to themselves. The results show that although infants are aware of shadows and show signs of having mastered the concept of shadow permanence at a fairly early age, compelling evidence of shadow self-recognition is developmentally delayed relative to what has been reported for the onset of mirror self-recognition, with most infants failing to show positive evidence prior to 3 years of age. The results are discussed in light of psychological differences that may exist between shadows and mirrors. Prior involvement and/or tutoring by parents about shadows had no effect on the emergence of shadow recognition. 相似文献

In order to test the hypothesis that the fear of flying is associated with irrational evaluative beliefs, as postulated by Rational Emotive Behavior Therapy for anxiety disorders, 15 fearful flyers and 7 non-fearful flyers participated in the Articulated Thoughts during Simulated Situations procedure. Six experimental scenes depicting some basic fears associated with the fear of flying and six supposedly non-anxiety provoking flight-related control scenes were used. The fear of flying group displayed significantly more irrational thoughts and significantly higher subjective ratings of anxiety on all experimental and five control scenes compared to the non-fearful flyers. Their negative cognitions were predominantly characterized by awfulizing and low frustration tolerance. The results are interpreted as offering support for the cognitive view that anxiety, and the fear of flying, are associated with negative cognitions characterized by a preoccupation with danger and with an overestimation of the seriousness of the perceived threat (awfulizing) and an underestimation of coping abilities (low frustration tolerance). 相似文献

A cognitive training program that taught both self-instructional and self-management skills was used with three 7-to 8-year-old hyperactive children. A multiple baseline across individuals design was used to evaluate the effects of training on on- task behavior and math accuracy. There were significant changes in math accuracy for all subjects, and two subjects showed significant improvements in on- task behavior. Evidence suggesting generalization to untrained behaviors was shown by an increase in self-correction of oral reading for all subjects. The results suggest that cognitive training specifically designed to promote generalization to classroom tasks can improve the classroom behavior and academic achievement of hyperactive children.The study was supported by a scholarship to the first author from the Specific Learning Difficulties Association (SPELD, Auckland). The authors would like to thank Mr. T. F. Walbran, deputy district senior inspector of primary schools, and Mrs. S. Gribben and the staff of Dominion Road Primary School; Mrs. F. Donovan helped with the collection of reading data and Dr. G. Arvidson gave assistance with data analysis. Special thanks also go to the graduate students who served as trainers or observers. 相似文献

A plural referring expression ('the F s' or 'Tom, Dick and Harriet') may be used to refer either distributively, saying something which applies to each of the F s individually, or collectively, to the F s taken as a single totality. Predicate Logic has to analyse both uses in terms of singular reference, treating them quite differently in so doing; but we think of such an expression as functioning in basically the same way in both kinds of use. This understanding can be vindicated if we recognise that what a plural referring expression picks out is not either an aggregate simpliciter or a set, but a plurality – an aggregate taken relative to a principle for individuating its constituents; this admits of being seen either as many things or as one. In any given case, it is the nature of what is being said about the plurality which tells us whether the reference to it is to be taken as distributive, collective, or a combination of the two. Talk about pluralities is extensional. Augmenting Predicate Logic to accommodate the distinctive inference-pattern associated with distributive plural reference is simple – and arguably necessary, to cope with cases in which distributive and collective reference are essentially combined (e.g., attributions of concerted action). 相似文献
