Methodological problems encountered in implementing conjoint analysis include (1) the impractically large set of multiattribute choice alternatives created by the factorial combination of more than a few attributes, (2) the hypothetical nature of the alternatives in the choice set, and (3) the assumption that each individual’s preferences can be described by the same composition rule. The techniques of tailoring, belief matching, and axiom testing are suggested as solutions to these problems, and their use is demonstrated in a conjoint analysis study of individuals’ contraceptive preferences. It is noted that tailoring and belief matching can also be used as methodological enhancements in functional measurement studies. 相似文献

This study examined the effects of instructional match and content overlap on students' ability to generalize from passage reading instruction. Four students with mild disabilities served as participants. Using a multielement design, students were instructed with passages at two levels of text difficulty (instructionally matched vs. instructionally mismatched), and generalization was assessed with passages at two levels of similarity to those instructed (low vs. high content overlap). Results indicated that students' oral reading accuracy and fluency showed the greatest degree of generalization when instructional materials were matched to the students' skill level and assessment materials were similar to those used during instruction. Moreover, these results were maintained at 1-month follow-up. The implications of these findings for classroom reading instruction and the assessment of students' reading skills are discussed. 相似文献

A 52-year-old right-handed woman who became deaf before the development of speech, suffered an occlusion of the right middle cerebral and a marked stenosis of the right anterior cerebral arteries. She showed no disturbance in the manual sign language or in finger-spelling, in contrast to previous reports of cases with left-sided damage. 相似文献

McCarthy (1990) contends that a cultural ideal of thinness (the thin ideal) causes depression and eating disorders to occur more frequently in women than men. She believes eating disorders are a way of coping with depression and hypothesizes that the thin ideal has its greatest impact during puberty when sexual attractiveness becomes important and changes in physical appearance increase the discrepancy between the adolescent girl's actual and ideal body image. The present study used a cross-sectional design of 5th, 8th, and 12th grade males and females (N = 599) to test several predictions from McCarthy's model. As expected, 8th and 12th grade females preferred a thinner than average body shape. They were more dissatisfied with their bodies than males and scored higher on measures of disordered eating. In contrast, before puberty (5th grade) boys were more depressed than their female peers but this pattern was reversed in 8th grade boys and girls. Paralleling changes in depression, disordered eating scores were highest in 8th and 12th grade girls. Both of these findings underscore the role of maturational factors in the onset of eating disorders. Although the sample was ethnically diverse and mainly from middle and low socioeconomic groups, there was a surprisingly high incidence of body dissatisfaction and symptoms of disordered eating. This illustrates the pervasiveness of thinness as a standard of feminine beauty in our society and the damaging effects it can have. 相似文献

The relationship between recruitment advertisement variables and applicant response rate was investigated. Three hundred and fifty companies were surveyed about applicant responses to their classified advertisements. One hundred and thirty-three surveys were completed and sent back for a return rate of 38%. The results of this study indicate that advertisements which include variables to enhance the physical features of the advertisement: such as white space, size, border, and graphics—are positively related to the quantity of an applicant pool. 相似文献

It has been suggested that the analgesic effect of morphine becomes attenuated over the course of successive administrations by a conditional, compensatory, hyperalgesic response elicited by the administration procedure, thus accounting (in part) for analgesic tolerance. On the basis of this associative model of tolerance, it would be predicted that established tolerance would be extinguished by placebo sessions. In experiments of apparently similar design (but conducted by different experimenters in different laboratories), data both confirming and refuting this prediction have previously been published. The present experiment, conducted jointly by the experimenters who reported the divergent findings, was designed to determine the reasons for the different results. It was found that placebo sessions do consistently attenuate morphine analgesic tolerance. Such extinction is not limited to the experimenter, drug preparation, rat strain, or apparatus used in the original, successful demonstration of the phenomenon, but rather is also demonstrable under conditions similar to those used in subsequent experiments which failed to demonstrate extinction of tolerance. Results of the present experiment suggest that the failures to demonstrate extinction of tolerance were attributable to insufficient extinction training. 相似文献

The effects of supervision support and supervisor race were examined in a 2 × 2 factorial design (high vs. low support × African American vs. Caucasian supervisor), with the inclusion of a no-supervision control condition. Sixty Caucasian women served as counselors in two counseling sessions with a confederate client. They were supervised by 1 of 6 experienced supervisors—3 African American and 3 Caucasian. Dependent variables included measures of counselor anxiety, perceived performance, satisfaction, and perceptions of the supervisory relationship. Results revealed a significant main effect for supervisor level of support but no significant effects for supervisor race. Implications of the findings and directions for future research are discussed. 相似文献

Although it is common in community psychology research to have data at both the community, or cluster, and individual level,
the analysis of such clustered data often presents difficulties for many researchers. Since the individuals within the cluster
cannot be assumed to be independent, the use of many traditional statistical techniques that assumes independence of observations
is problematic. Further, there is often interest in assessing the degree of dependence in the data resulting from the clustering
of individuals within communities. In this paper, a random-effects regression model is described for analysis of clustered
data. Unlike ordinary regression analysis of clustered data, random-effects regression models do not assume that each observation
is independent, but do assume data within clusters are dependent to some degree. The degree of this dependency is estimated
along with estimates of the usual model parameters, thus adjusting these effects for the dependency resulting from the clustering
of the data. Models are described for both continuous and dichotomous outcome variables, and available statistical software
for these models is discussed. An analysis of a data set where individuals are clustered within firms is used to illustrate
fetatures of random-effects regression analysis, relative to both individual-level analysis which ignores the clustering of
the data, and cluster-level analysis which aggregates the individual data.

Cummings and Carr (2009) compared two methods of data collection in a behavioral intervention program for children with pervasive developmental disorders: collecting data on all trials versus only the first trial in a session. Results showed that basing a child's progress on first‐trial data resulted in identifying mastery‐level responding slightly sooner, whereas determining mastery based on all trials resulted in slightly better skill maintenance. In the current replication, no such differences in indication of mastery or maintenance were observed when data were collected on all trials or the first trial. 相似文献
