This paper identifies issues and techniques useful to psychologists interested in applied research for computer applications. Applied research includes guideline research, product development evaluation, and field trial evaluation. Suggestions for improved guideline research involve screening the problem to determine its potential usefulness and screening the design to make sure it involves sufficiently representative tasks, subjects, and materials for the desired generality. Product development evaluation requires techniques for testing users that are fast, flexible, and inexpensive, such as “user trials” of products in ergonomics and “user edits” for testing documentation. Field trials of office automation or videotex systems lead to decisions about further introduction of those systems. A methodology for planning the research component of field trials, “evaluation assessment,” provides a set of steps to use in deciding which design and measures should be collected. 相似文献

As powerful socializing agents, schools can be important facilitators in changing social norms of gender-role expectations. This research study was designed to determine the impact of an interdisciplinary course in the effects of sex-role stereotyping on awareness and attitudes of the participants. The high school students in the experimental program increased their awareness of the stereotyping process and the effects of narrowly defined sex roles. These students perceived the roles of males and females in a more socially androgynous context than did students who did not take the course. 相似文献

Three different stimulus modalities (line length, number, and sound pressure) were judged by magnitude scaling techniques and by 7-, 15-, 31-, and 75-point category scales. All of the 40 subjects were given the same number stimuli, but two different sound-pressure ranges were presented (each to 20 subjects) and four different line-length ranges were presented (each to 10 subjects). Analyses of lack of fit for various simple functions were performed to determine bestfitting functions. The simple power function was often found to be an adequate fit to the data for all the response modalities used, although all of the response modalities were sensitive to changes in stimulus range. For simple power functions, the category-scale exponent was a function of both the range of stimuli and the number of categories provided. Category scales did not always produce exponents smaller than those obtained with magnitude estimation, which calls into question the concept of a virtual exponent for category scales. 相似文献

Children's perceptions of parental behaviors 总被引:2,自引:1,他引:1

Children's perceptions of positive and negative parental behaviors were assessed using a newly-developed scale, the Parent Perception Inventory (PPI). Reliability and validity were examined across a sample of 75 children aged 5 to 13 using additional measures administered to the children and measures completed by their parents. The scale showed acceptable levels of internal consistency. No effects of children's age were apparent, but effects of the child's and parent's gender were found. Boys reported more positive parental behaviors, particularly for fathers, and children reported more negative (disciplinary) behaviors by mothers. PPI scores were predictably related to child's self-concept and behavior problems (convergent validity) and generally unrelated to measures of child's achievement (discriminant validity). As predicted by family systems theory, children from nondistressed families viewed their parents as behaving more similarly on the PPI than did children from distressed families. 相似文献

A KIM-1 single board microcomputer implementation of a cardiotachometer that provides a low-cost versatile heart-rate data acquisition system is described. Unique features include telemetry, a composite video output signal of a video frame displaying elapsed time and heart-rate, and a TV camera signal of the behavior. Data is videotape- and/or audiotape-recorded for further analysis with a larger computer. 相似文献

L.B. Brown's model of religious faith posits two bipolar religious orientations (intrinsic-extrinsic and autonomy-observance) that represent a two-dimensional space in which a religious believer can be located. This paper proposes a developmental sequence within Brown's model. The psychometric tradition of religious orientations is combined with a developmental tradition. The developmental process is consistent with models by A. Maslow, L. Kohlberg, J. Fowler, and J. Loevinger. Religious faith typically springs from extrinsic motivations. Most religious adherents achieve the next level, observance, or identification with a religious community and its creeds. Some progress to intrinsic religiousness, and fewer attain religious autonomy. 相似文献

Mothers of premature and full-term infants viewed and heard videotapes of premature and full-term infants. The onset of crying by both infants elicited physiological arousal (evident in blood pressure, skin conductance, and heart rate increases) in the adults. The mothers of premature infants responded with especially marked arousal to the infants' cries. These mothers also reported that they were more attentive and alert while the infant was crying. The subjects responded similarly to the cries of full-term and premature infants. Mothers who described their own baby as easy exhibited a lower increase in diastolic blood pressure and heart rate, and reported being more alert, attentive, and willing to interact with the stimulus babies than those whose own baby appeared “difficult.” 相似文献

Two main questions were asked regarding young children's beliefs about causal mediation: What sorts of beliefs about causal mediation are reflected by children's incomplete explanations of causal situations? In particular, do children hold a false belief in action at a distance or do they realize that something must mediate between cause and effect? When presented with a non-visible connection between cause and effect (Experiment I), the children's incomplete (Piagetion Stage 1) explanations either reflected the correct expectation of a mediating connection or else merely reflected identification of the causal agent and no concern one way or another with the issue of causal mediation. This was also the case when the mediating connection was visible and present at the outset (Experiment II). In neither experiment (both of which involved mechanical causation) was there evidence of a false belief in action at a distance. A third experiment involved instances of electrical causation in order to maximize the chances of tapping a false belief. The rationale was that, in their everyday lives, although children do have first-hand experience with the mediating connection in instances of mechanical causation, they do not have such experience with instances of electrical causation. The results from the third experiment were analogous to the results in the other two. It was concluded that, with respect to instances of physical causality, young children do not hold a false belief (in action at a distance) that is later relinquished. Rather, their concerns are, at first, restricted to identifying the causal agent and do not include any beliefs, true or false, about the issue of causal mediation. When they eventually do deal with the question of causal mediation, children hold approximately correct beliefs. In terms of school situations, these findings suggest a shift from providing the child with disconfirming data that will aid him in relinquishing his false beliefs to providing him, instead, with additional data that will supplement his existing, approximately correct beliefs. 相似文献
