Battig (1965) published a correction adjusted-learning method for ensuring equal learning of all items in a paired-associate list. The present experiment tested the adequacy of his technique by using response latency as a measure of learning. The results showed that the Battig procedure was not entirely successful in equating the level of learning across items.  相似文献

If the discriminal distributions of signal-detectability theory evolve in time according to a normal Markov process, they can be characterized by Brownian motion generalized with a constant bias determined by signal strength. If the process is stopped at the first occurrence of a preset criterion displacement, the resulting latency distribution provides a model for the central component of simple reaction time. Discussed are properties of the distribution which should be useful in obtaining experimental predictions from neural-counting assumptions, and in relating reaction times to basic variables of the theory of signal-detectability.This paper was written while the author was on a post-doctoral fellowship at the Mental Health Research Institute, University of Michigan, supported by U.S.P.H.S.

During the past few years urban fire companies have responded to a vastly increased number of false alarms, especially from lower income areas. In a preliminary attempt to understand this phenomenon, two studies were conducted. In the first, several environmental variables, in addition to average neighborhood income, reported harrassments of firemen, and type of alarm box, were correlated with false alarm frequencies for randomly selected alarm boxes in lower income sections of Brooklyn. Results of a step-wise multiple regression analysis indicated that (a) a linear combination of six environmental variables accounts for 73% of the variance in false alarms, (b) this relationship is not due simply to differences in average neighborhood income, and (c) false alarms are associated geographically with harassments. The results suggested that false alarms should be interpreted as expressions of protest. The second study explored the beliefs and attitudes of ghetto residents and revealed that young nonwhites showed most hostility to the fire department. Although most respondents expressed positive attitudes toward firemen, many believed they do unnecessary damage; and some respondents linked this with racism. Other causes for anger not directly related to the fire department were also mentioned, including the environmental factors emphasized in the first study. The findings raise several questions amenable to social psychological investigation and suggest ways to reduce false alarms, but it seems unlikely that the problem can be solved until deeper racial and class antagonisms are reduced.  相似文献

Previous investigations of the social behavior of handicapped preschool children (Journal of Applied Behavior Analysis, 1974, 7 , 583–590; Journal of Applied Behavior Analysis, 1976, 9 , 31–40; Journal of Applied Behavior Analysis, 1977, 10 , 289–298) demonstrated that introduction of adult or peer confederate intervention agents produced substantial increases in levels of positive social behavior emitted by the subjects. In addition, it was observed that changes in rates of positive social behavior emitted by recipients of intervention tactics were accompanied by parallel changes in rates of positive social behavior emitted by interacting peers. However, with one limited exception, sudden removals of arranged intervention procedures were followed by immediate reductions in the levels of positive social behavior emitted by subjects and peers in each study. The current investigation was designed to examine the effects of response-dependent removal of intervention procedures on the positive behavior of three socially withdrawn preschool boys. Interactive effects on the social behavior of classroom peers who did not receive adult prompts and contingent attention events were also examined. A combination of withdrawal of treatment and multiple baseline procedures was employed. The three target subjects received fixed numbers of prompts and contingent attention events during Intervention I and Intervention II, Phase 1 conditions. During Intervention II, Phase 2 conditions, prompts and contingent attention events were reduced on a response-dependent basis for two subjects and on a response-independent basis for the third subject. The results suggest that: (a) the intervention procedures produced marked increases in positive social behavior emitted by each subject; (b) response-dependent fading and thinning, contrasted with response-independent tactics, maintained levels of positive social behavior equivalent to those observed during Intervention I and Intervention II, Phase 1 conditions; (c) changes in positive and negative behaviors emitted by peers paralleled changes in positive and negative behaviors emitted by each subject; and (d) no “spillover” of treatment effects was noted for subjects during periods in which they were not direct recipients of intervention procedures.  相似文献

According to the theory of objective self-awareness (Duval & Wicklund, 1972), the concept of generalized drive is unnecessary, its explanatory function having been replaced by the concepts of self-evaluation and desire to be “correct”. An experiment was designed to compare alternative predictions from the drive and self-awarencess theories. Subjects listened to music in the presence of a mirror and, at another time, not in the presence of a mirror. The effect of self-consciousness on several habitual behaviors related to smoking was assessed. It was known that the subjects believed the number of cigarettes one should smoke “ideally” was significantly less than the number they actually smoked. Hence, the theory of objective self-awarencess predicts decreased smoking in the presence of the mirror, while a drive theory interpretation of self-consciousness predicts the opposite. Results generally supported the drive theory.  相似文献

A simple EEG electrode for Intrauterine use In the human fetus is described. The stainless steel screw electrode possesses low noise characteristics, is constructed from commercially available material, and is easily attached to the fetal head during labor. Principles of optical signal analysis as an improved method of spectral analysis of the fetal EEG are also presented. The optical system provides visual display and hard copy output of the fetal EEG.  相似文献

Like orthogonal polynomials, the sine and cosine components used in Fourier analysis are orthogonal under summation over equally spaced points. Therefore, they can be used in the same way as orthogonal polynomials are used with analysis of variance. They are usually used on records consisting of sequences of observations taken equally spaced in time. Analysis of variance can be performed on replicated records. The most straightforward cases occur under the following conditions: (1) The phenomenon is periodic, (2) the phenomenon is coherent (synchronized) over the various replicates, (3) the record length is an integral multiple of the fundamental period, and (4) the phenomenon is not buried too deeply in noise. Two numerical examples are examined that satisfy these conditions. Planning is illustrated for a case that violates Conditions 3 and 4.  相似文献

Abusing and high-risk families have been seen over three years at a new treatment resource with a family therapy orientation. The families present with established resistance to any treatment intervention and many have defeated a succession of previous helping agencies. Initial typology and treatment strategies are described with the aim of more systematic selection of therapeutic techniques.  相似文献

The follow-up data reported represent a long-term (3 to 9 years out of treatment) evaluation of 40 children who were clients of the Regional Intervention Program (RIP) from 1969 to 1978. As 3-, 4-, and 5-year olds, these youngsters exhibited severe and prolonged tantrums, continual opposition to adults' requests and commands, and physical aggression toward parents. Each child and mother participated in a standardized intervention package modeled after Wahler's Opposition Child Treatment. Results from school and home-based follow-up showed that: (a) commands, demands, or requests made by parents were likely to be followed by former clients' compliance; (b) former clients' social interactions in the home were overwhelmingly positive and their nonsocial behavior was by and large appropriate; (c) parent behavior in the home was consistent with the child management skills taught many years ago; (d) there were no differences between the compliant, on-task, social interaction and appropriate/inappropriate nonsocial behaviors of former clients and randomly selected class peers; (e) there were no differences in teachers' commands, negative feedback, positive social reinforcement, and repeated commands that were directed toward either former clients or randomly selected class peers; (f) both teachers' and parents' rating of former clients on the modified Walker Problem Behavior Checklist were highly correlated; (g) there were no differences in teachers' rating of former clients and class peers; and (h) of all the studied demographic variables, only age that treatment began and family intactness were related to current levels of behavior.  相似文献

This study investigated the use of series of nocturnal dream reports to diagnose patterns of family functioning. Five families (twenty one subjects) collected a total of 126 dreams. A Treatment Group consisted of two families undergoing family therapy whilst a Non-Treatment Group, comprising three families, was drawn from a population ranging from severely disturbed to superior family functioning. The manifest content of the dreams was analysed, qualitatively and quantitatively. The presenting problem, case history, therapeutic processes and outcome were unknown to the dream researcher. The family therapist was blind to the dream content and dream analysis. Each family was independently rated by the therapist and the dream researcher. The agreement between the two assessments was highly significant. In addition, the problem areas, family transactions and treatment outcome were correctly identified by the dream researcher. It was concluded that analyses of dream series reflect the problem areas encountered by a family system. Implications for therapeutic strategies are discussed.  相似文献
