The first part of the paper reports an investigation of the effects of the concreteness-imagery (C-I) value of stimuli and responses on the long-term retention of paired-associate lists. With degree of learning equated, the measures of retention after a 1-week interval showed a significant interaction of Stimulus by Response C-I: When the responses had a high value, recall was substantially better with low than with high stimuli; when the responses were low, there was no reliable difference as a function of stimulus value. Recall was best when abstract stimuli were paired with concrete responses. The second part of the paper is addressed to some current issues in the analysis of coding processes. Major emphasis is placed on the experimental and theoretical differentiation of encoding and decoding processes. 相似文献

The present paper describes a simple and accurate technique for the artificial respiration of curarized rats that avoids the trauma involved in a tracheotomy. Success of the technique depends on the proper positioning of a special face mask on the rat. The results of an experiment on arterial blood gases in 48 curarized rats are presented to illustrate the accuracy and effectiveness of the techniques described. 相似文献

The relationship between apparent size and apparent depth in certain forms of the Müller-Lyer illusion is explored both Experimentally and theoretically. The Experimental results show that the apparent Sizes and apparent distances of the Müller-Lyer shafts in the normal and in the “reverse” illusions are related to each other. They also contradict specific predictions About the apparent depth location of Müller-Lyer shafts derived from the Misapplied size-constancy theory and Emmert’s Law. These results are interpreted In terms of the operation of the size-distance Principle, and this interpretation is supported by observations of other illusions. 相似文献

An experimental study of short-term memory for lists of familiar English words is reported. Lists of 10, 20, and 30 unrelated words were presented at a 1-sec. rate. Retention was measured by free recall after intervals of 0, 15 and 30 sec. A counting task was used to prevent rehearsal during the retention interval. The absolute level of recall increased with length of list whereas the percentages retained showed the reverse trend. The recall scores decreased steadily as a function of retention interval, with the rates of forgetting comparable for the three lengths of list. The decline in the amount recalled was due in large measure to the loss of the terminal items in the list. Consequently, the pronounced recency effect present on the immediate test of recall was progressively reduced as a function of time. By contrast retention of the initial part of the list was relatively stable. These variations in rate of forgetting are attributed to differences among serial positions in susceptibility to proactive inhibition. 相似文献

To explain changes in the sociometric configuration of a group through time, a problem arises of the extent to which such changes may be viewed as the aggregation of part-processes occurring at the level of two-person choice structures. A possible model is a Markov chain in which three possible states are mutual choice, one-way choice, and indifference, one realization for each pair of choosing individuals in the group. Choice data for an eighth-grade classroom are fitted to this model and are used to answer questions of constancy of transition probabilities, order of the chain, and sex differences. 相似文献

The purpose of the study was to find the relationships between SVIB patterning and psychological adjustment, maturity, and intelligence. Male SVIB profiles were categorized as Primaries, Secondaries, or No Patterns. The three groups were compared on MMPI scales, using a two-factor ANOVA; no differences between the groups were obtained at the .05 level of confidence. The groups were compared on age and aptitude scores, using in each case a simple ANOVA; no mean differences were obtained at the .05 level of confidence. Related research was reviewed and this study was found to be confirmed by several others. There is little support in the literature for the widely held belief that something is “wrong” with the client who has an unpatterned SVIB profile. 相似文献

Considering an interactive computer as a social stimulus suggests that contemporary social psychological theories can contribute to the prediction of user attitude and performance. In order to assist in the systematic exploration of this possibility, we developed DIALOGUE, an on-line system to investigate the effects of varying the computer’s responses to the user. This system involves a presentation program that displays the computer’s responses, performs the pacing of video information, and collects a variety of measurements, including the user’s response time and the number of correct/incorrect user responses. DIALOGUE also includes a data manager that allows the experimenter to examine or modify the information collected by the presentation program. Utilizing DIALOGUE, we conducted a preliminary investigation of one aspect of human-computer interaction, the effects of varying the degree of human-like responses exhibited by the computer. Results suggest that (1) there are underlying dimensions of judgment involving perception of interactive computers, (2) a manipulation of human-like computer responses is reflected primarily in certain of these dimensions, and (3) such a manipulation influences user performance and feelings of responsibility. Factors related to the implementation of DIALOGUE are considered, and its potential for investigations of a variety of human-computer interactions is discussed. 相似文献

Sinusoidal gratings of various spatial frequencies were used as masking stimuli in a detection task and a vernier acuity task. The test stimuli were 1 cycle/deg square-wave gratings. The spatial frequency of the most effective mask was 1 cycle/deg for the detection task but 3 cycles/deg for the vernier acuity task. The different masking functions for the two tasks show that the visual system analyzes the square-wave stimulus into its various spatial-frequency components. Since the test stimulus was the same for both tasks, the different masking functions may be the result of an attentional mechanism that weighs the importance of the output from various spatial-frequency analyzers. Whether the information from a particular spatial-frequency analyzer is attended or not depends upon the task the visual system must perform. 相似文献
