In most cases, there is no direct correspondence between the objectives that users of an interactive device may be led to formulate and the commands that enable them to attain those objectives. In order to set up what Young (1981) calls a “mapping” between the “task and action arenas”, users must (1) reorganize their objectives in order to adapt them to the capabilities of the device and (2) if necessary, combine several commands to reach a given objective. In doing so, they are assumed to rely on a “conceptual model” of the device, a notion whose cognitive status remains to be clarified. In this article, the editing keys of the MS/DOS operating system are taken as an example and described according to two different conceptual models. The links between the task and action arenas, in these two conceptual models and in a third one called the “mixed model”, are analysed in detail. Finally, the performance of three groups of subjects, while editing a line of text, are compared. All three of the dependent variables analysed are shown to vary according to how the objective is assumed to be formulated in the three conceptual models. Some hypotheses are presented concerning the cognitive mechanisms involved in such a situation. 相似文献

The authors examined whether variations in day-to-day estimates of personality characteristics, which are often treated as error, are instead predictable and meaningful. Using event-sampling and spectral analysis, they found that variations in interpersonal behavior over weekly periods were cyclic and normative. Dominant, submissive, agreeable, and quarrelsome behaviors rose during the week and fell on the weekend. The more general dimensions of agency and communion exhibited opposite patterns of cyclicity, with agency rising and communion falling during the week. Interpersonal traits were not useful in predicting behavior cyclicity. Extraverts exhibited a daily cycle, partially mediated by more varied partners and social behaviors during evenings. Findings are discussed with reference to conceptions of personality expression as dynamic yet stable processes. 相似文献

In recent years, choice making has been evaluated as an intervention for people with disabilities. This review examines applied research during the past two decades using choice as a distinct intervention or as part of an intervention package. Fourteen studies published between 1975 and 1996 were identified that implemented choice as an intervention to increase or decrease a target behavior. These studies applied choice-making in the following three broad areas: (a) vocational or domestic activities; (b) academic activities; and (c) leisure, recreational, or social activities. All of the studies indicated that choice-making procedures resulted in behavioral improvements with some, if not all of the participants. 相似文献

The Effect of Genetic Counseling on Knowledge and Perceptions Regarding Risks for Breast Cancer 总被引:1,自引:0,他引:1

In 1994, a clinic for cancer risk counseling was opened at Hadassah University Hospital in Jerusalem. Most of the counselees have been women who had breast cancer and/or a relative with breast cancer. In order to evaluate the effect of this counseling on women's knowledge and perceptions regarding the risks for breast cancer, a questionnaire was given before and after the counseling session to 60 healthy women who came to the clinic because they have relatives with breast cancer. According to the genetic counselors' estimations, most of these women had a significantly increased risk (compared to the general population) of developing cancer. Before counseling, the women overestimated the population risk for breast cancer, the contribution of heredity to morbidity of cancer, and their own risks to get cancer. After counseling session, they gave reduced estimates, closer to the real ones. The subjective perceptions regarding these risks were reduced after counseling, except for the perceptions regarding their relativerisks which have not changed after the counseling. About 90% of the women who came to the clinic wanted to be tested for genetic predisposition to cancer. For most of these women, the expectations that the test can rule out a genetic predisposition to cancer became more realistic after the counseling. The option to first test an affected relative was offered to all families, and a test was actually conducted in 75% of the families. 相似文献

Client-centered consultation was effective in helping a teacher to decrease one child's disruptive classroom behavior, and consultee-centered consultation helped the teacher improve her control of the class as a whole. Initially, a client-centered reinforcement program effectively decreased the disruptive behavior of one target child. Later, attention to the teacher's feelings about being the authority figure in the classroom was used in an attempt to modify the behavior of the entire class. The data describing the behavior of a second child in the classroom suggested that this consultee-centered consultation was followed by less classroom disruption. In addition, anecdotal observations indicated that consultee-centered consultation was effective in modifying the behavior of both the teacher and the rest of the class. 相似文献

In an experiment examining retroactive interference effects in a frequency-judging task, all Ss were presented with a list of words occurring varying numbers of times according to either a massed- or distributed-practive (MP or DP) schedule. They were then asked to judge how often each word had occurred. Following this, Ss were given one of four types of second tasks a second list with different items followed by a frequency-judging task for that list (Condition New): a second list with items repeated from the first list but with different frequencies for each item, while either maintaining items as either MP or DP items (Condition Same) or switching MP items to DP, and vice versa (Condition Reverse): followed by a frequency-judging task for the second-list frequencies only: or a puzzle task for the amount of time required for second-list presentation and judgment in the other conditions (Condition None). Finally, all Ss were asked to recall List 1 frequencies, List 2 frequencies were less discriminable in Conditions Same and Reverse than in Condition New. Recall of List 1 frequencies, however, was not different for these three groups, but was poorer than in List 2 frequency judgments were not independent of List 1 frequencies. 相似文献
