In two of the three experiments that are reported subjects were trained in either a blocked or a random practice schedule and allowed to self-select the amount of time they used to plan an upcoming movement. According to the reconstruction hypothesis (Lee & Magill, 1985) random practice participants engage greater movement planning processes (i.e. action plan re-construction) during acquisition than do their blocked practice counterparts. It was predicted that such reconstructive activity would be manifest as greater study time being used by random practice subjects as they readied themselves for an imminent response. Data from Experiments 1 and 2 supported this study time prediction while also revealing the typical retention benefit associated with random practice. Interestingly, the acquisition benefit often apparent with blocked practice was not evident when the random practice participants were given sufficient time to plan the upcoming response. These conclusions were supported by data from Experiment 3 that involved a direct manipulation of the amount of study time afforded random and blocked practice participants. Taken together, these data are consistent with the suggestion from the reconstruction hypothesis that more time is necessary for intratrial planning processes during random practice formats. Furthermore, acquisition differences that are commonly observed between high and low contextual interference practice conditions may, at least in part, be associated with the completion of the extra planning processes entertained by random practice participants as the movement is being executed. 相似文献

Group membership is analyzed from the perspective of developmental theory. Maladaptive or nontransitional uses of the groups of everyday life, such as work and social groups as well as therapy groups, are discussed and illustrated with clinical examples. It is recommended that therapists pay attention to the nature and meaning of their patients' involvements in these sorts of groups, keeping in mind that the meanings of such affiliations are particularly influenced by developmental factors. 相似文献

Two studies were conducted to develop a psychometrically sound scale to measure attitudes to ward censorship. In the first study, 37 initial items were administered to 109 college and high school students. Additional measures were also included for validation purposes. Factor analysis and item-total correlations were used to select items for the final scale. Results revealed two distinct factors alluding to the possibility of a multidimensional construct. Reliability coefficients indicated that both factors were internally consistent. Correlations with additional measures provided evidence for the criterion and convergent validity of the scale. The second study used a sample of 150 college students to replicate the initial findings and to establish testretest reliability. 相似文献

The redundant-signals effect is the observed RT advantage for trials presenting two or more targets, as compared with trials with only one target Two general classes of parallel-processing model have been proposed to explain this effect race models (e.g., Raab, 1962) and coactivation models (e.g., Miller, 1982). Various distributional analyses have been used in work aimed at discriminating between these two model classes. The present study reexamined one of these tests—the combination-rule regression analysis based on variable-criterion theory (Grice, Canham, & Boroughs, 1984)—by applying it to the data from two sets of simulated experiments. One set of simulations assumed coactivation; the other set assumed an independent race on redundant-target trials. Nearly identical combination-rule values were observed in the two sets of simulations. This finding shows that the combination rule of variable-criterion theory does not discriminate between models capable of explaining the redundant-signals effect The implications of this finding are briefly discussed 相似文献

A community intervention to mobilize positive reinforcement for not selling tobacco to young people was evaluated. The intervention
had five components: (a) mobilization of community support, (b) merchant education, (c) changing consequences to clerks for
selling or not selling to those under 18, (d) publicity about clerks’ refusals to sell, and (e) feedback to store owners or
managers about the extent of their sales to adolescents. A multiple baseline design experiment was conducted, in which two
small Oregon communities received the intervention, while two others continued in baseline. Outlets’ willingness to sell was
assessed repeatedly by teenage volunteers. The intervention significantly reduced the proportion of stores willing to sell.
Mobilizing socia and material reinforcement for stores not selling tobacco to young people is a viable means of reducing such
sales. It may be especially valuable in communities where laws against sales to minors go unenforced.

The conjunction fallacy, in which individuals report that the conjunction of two events is more rather than less likely to occur than one of the events alone, is a robust phenomenon. We assessed the possibility that an analysis in terms of functional measurement methodology might be consistent with occurrence of the fallacy. A 3 × 3 design in which we varied the judged likelihood of the two components constituting the conjunction permitted us to assess the possibility that subjects judge the likelihood of conjunctions by averaging the likelihood of their component parts. The results were consistent with this possibility, and this interpretation was supported by analysis of the results in terms of functional measurement methodology. 相似文献

Research indicates that graduate programs in counseling and clinical psychology are beginning to include more courses on multicultural issues. Little data is available, however, concerning the inclusion of training in multicultural issues in predoctoral psychology internship training programs. This study examined the amount and type of such training actually occurring at predoctoral psychology internship training programs in university counseling centers. 相似文献

Four experiments are reported examining the locus of structural similarity effects in picture recognition and naming with normal subjects. Subjects carried out superordinate categorization and naming tasks with picture and word forms of clothing, furniture, fruit, and vegetable exemplars. The main findings were as follows: (1) Responses to pictures of fruit and vegetables (\ldstructurally similar\rd objects) were slowed relative to pictures of clothing and furniture (\ldstructurally dissimilar\rd objects). This structural similarity difference was greater for picture naming than for superordinate categorization of pictures. (2) Structural similarity effects in picture naming were reduced by repetition priming. Repetition priming effects were equivalent from picture and word naming as prime tasks. (3) However, superordinate categorization of the prime did not produce the structural similarity effects on priming found for picture naming. Furthermore, such priming effects did not arise for picture or word categorization or for reading picture names as target tasks. It is proposed that structural similarity effects on priming object processing are located in processes mapping semantic representations of pictures to name representations required to select names for objects. Visually based competition between fruit and vegetables produces competition in name selection, which is reduced by priming the mappings between semantic and name representations. 相似文献

The utilization of the research process as an intervention has recently been described in the family therapy literature. However, it is important to draw a distinction between research as intervention and research as a unique family therapy intervention technique. From a family systems perspective, research as an intervention technique may make therapy more palatable for some families. A case study is presented in which this technique created the context for change for a family involved in a chronic illness research project.The author would like to thank Dr. Wendy L. Watson for her participation as a member of the clinical team and Drs. Fabie Duhamel and Wendy L. Watson for their helpful critiques on earlier drafts of this paper.Supported by a grant from the Albert Foundation for Nursing Research. 相似文献
