After administering interviews covering health conditions, physical limitations, optimism, and affect to 851 older adults, interviewers rated the health and sickness of the interviewees. Observers' ratings of health and sickness were more highly correlated with the severity of participants' self-reported health conditions than were participants' self-ratings of health. This finding is likely attributable to participants' self-ratings of health being more highly correlated with their optimism and positive affect than the observers' ratings. Participants rated as sicker and less healthy at baseline were at a 3 times greater risk for mortality over 114 months. This association was independent of participants' self-rated health as well as demographics, self-reported health conditions, years of smoking, physical limitations, body mass index, optimism, and affect.  相似文献

A grade-four class teacher was trained in the use of token and verbal reinforcement by an experienced "token helper", who demonstrated the procedures in the classroom. The introduction of a simple token system resulted in significant decreases in the disruptive behavior of 10 pupils in two morning periods. When the token helper withdrew from the classroom, the teacher managed the token system and maintained disruptive behavior at lower than baseline levels.  相似文献

Six elementary school children served as subjects in an experiment comparing the relative effectiveness of (1) token reinforcement, in which children received tokens for attending and for correct arithmetic performance; (2) response cost, in which children received “free” tokens at the start of a period but lost them for inattention and for arithmetic performance below a specified level; and (3) a combination of both token reinforcement and response cost. During training, the six subjects received all three procedures in counterbalanced sequence. The effects of the three procedures were assessed by a within-subject comparison divided into three phases: (i) baseline, (ii) training, (iii) withdrawal of tokens. Introduction of the three token procedures markedly increased the two dependent measures. However, there were no differences across the procedures in the amount of change produced in either attending behavior or arithmetic performance. During baseline, the subjects averaged 29% attending behavior and 6.4 correct problems. These levels increased to 85% for attending behavior and 11.4 correct problems for arithmetic performance during training. Removal of all token procedures significantly decreased attending behavior (to an average of 65%), but produced a nonsignificant reduction in arithmetic performance (to an average of 7.6 correct problems). There was evidence that this lack of differential effects of the three token procedures was not due to an inability to discriminate among them. Furthermore, the subjects were evenly divided in their preference for the three procedures.  相似文献

The effects of reward and cost token procedures on the social and academic behavior of two groups of elementary special-education students were assessed using a reversal design. Behavioral observations of three target subjects in each group revealed that both procedures were about equally effective in reducing rule violations and off-task behavior. Records kept on the daily arithmetic performance of all subjects showed that output doubled in both groups during the token phases, although accuracy remained unchanged. When students were allowed to choose either contingency, no pattern of preference was established. Small differences were found in teacher behavior: the reward procedure led to an increase in approval comments but cost procedures produced no changes in teacher behavior.  相似文献

Agreement between adolescents, mothers, fathers, and teachers on adolescents' personality traits was investigated in a longitudinal study. The targets for personality ratings were the adolescents who participated in the European Youth Heart Study in Estonia. There were 593 participants in the first wave and 480 participants in the follow-up study 3 years later. Adolescents' self-reports as well as father, mother, and teacher ratings were collected using questionnaires to measure the five-factor model of personality. In both waves, inter-rater agreement was highest between mothers and fathers, was low to moderate for parent-self ratings, and was lowest for ratings between self and teacher, mother and teacher, and father and teacher. Test-retest correlations were moderate for parent and self-ratings but failed to reach statistical significance for three of the five teacher-rated traits, suggesting lower reliability of teacher ratings. Possible explanations for the low agreement between teachers and other judges are discussed.  相似文献

Systematic reinforcement: academic performance of underachieving students   总被引:1,自引:0,他引:1  
The effect of contingent tangible and social reinforcement on academic performance was investigated in an experimental classroom of 25 selected underachieving students. Measures were taken of both teacher and child behavior during a baseline and two experimental treatment periods. During Treatment I, a point system with tangible backup reinforcers was combined with contingent social reinforcers dispensed by the teaching staff to assess the effects on three measures of academic performance (i.e., per cent of time at work, work output per minute, and accuracy). During Treatment II, the contingencies for the tangible reinforcers were terminated while social reinforcement was continued to see if the positive effects of Treatment I on academic performance would persist. The results show that with combined tangible and social reinforcers, students' work time, rate of output per hour, and accuracy in all activities substantially increased. After termination of the tangible reinforcers, the students maintained their high rates of output per hour and accuracy for the remaining period of the study while the total amount of time at work returned to the baseline level.  相似文献

Nine adolescent boys with a history of high rates of disruptive classroom behavior were selected from a psychiatric hospital school and placed in a remedial reading class after school in which various factors in a token reinforcement program involving self-evaluation were investigated. The effects of self-evaluation, in the form of a rating the students gave themselves about the appropriateness of their classroom behavior, were first assessed. While the students' ratings of their own behavior correlated highly with the teacher's ratings and evaluations made by independent observers, the self-evaluations did not lead to a reduction in disruptive behavior. A token reinforcement program, in which the teacher rated the students' level of appropriate behavior and in which the students traded earned rating points for prizes, clearly led to a reduction of disruptive behavior. When the students were given the opportunity to evaluate their own behavior and to receive rewards in exchange for the evaluation, they returned to their former rates of disruptive behavior.  相似文献

Abstract

The influence of five background variables (age-group. sex. work status. smoking status. household income) on four health ratings (current self-rating. estimated age/sex average rating, best possible self-rating. health satisfaction self-rating) was investigated in the context of a local survey with 377 respondents. Main effects of age-group. smoking status and work status on current health self-ratings were obtained as predicted. Age-group was also found to affect age/sex average ratings. health satisfaction and best possible health self-ratings, with smoking status also influencing the last of these. Mediation of the obtained effects was also examined by controlling for three independent self-report measures of health status in the analyses. Two relevant theoretical notions were examined in analysing the data. The health satisfaction findings as a function of age-group proved consistent with Multiple Discrepancies Theory. Strong support was obtained for a social representations approach. particularly through the direct effects (unmediated by the independent health status measures) of age-group on age/sex average health ratings and best possible health self-ratings. This suggests the contribution of a social consensus about age as having a negative influence on health status. Directions for further research are briefly outlined.  相似文献

The effects of token reinforcement and response cost on the accuracy of spelling performance with three adolescent special education students were examined. A multiple-baseline design across students was used to evaluate the effects of token reinforcement and response cost intervention. A greater percent of accuracy on daily spelling exams was obtained during the token reinforcement plus response cost condition than during the baseline condition. This was replicated for each student. Follow-up data collection indicated maintenance of behavior change over time. The benefits of implementing a token economy with a response cost component with middle-school students with behavior disorders were discussed. © 1998 John Wiley & Sons, Ltd.  相似文献

The effectiveness of a token economy system in producing improvement in the academic performance of children with Down's syndrome was tested. One group of seven children received token reinforcement for correct responses and showed significant improvement both in arithmetic and language. A second matched group of six children received only verbal praise for correct responses to the same instructional materials and failed to improve in arithmetic but showed significant gains in language. Re-test scores one year later revealed that the Token Group maintained its gains in both subjects whereas the language performance of the No-Token Group showed a significant decline.  相似文献

An alternating treatments design was used to compare the effects of baseline, interspersed brief problems, and interspersed brief problems plus token reinforcement on students' endurance while completing math worksheets. By pairing the completion of brief problems with token reinforcement, the role of problem completion as a conditioned reinforcer was examined consistent with the discrete task completion hypothesis. Four 5th grade students who were low achieving in math participated. Each day the students completed a stack of math worksheets containing 3-digit by 3-digit addition problems with or without interspersed single-digit problems for 10 min. Dependent measures included total digits correct per session and during each min of the 10 min work period (i.e., a measure of endurance). Results indicated that total digits correct per session was highest during the interspersal plus reinforcement condition followed by interspersal and then baseline for three of the four students. In addition, both interspersal conditions resulted in greater endurance than baseline. Limitations of the current study and implications for increasing students' persistence on classroom tasks are discussed.  相似文献

This study examines the effects of contingent reinforcement under conditions of pupil-selected and teacher-selected performance standards upon pupils' academic response rates. The academic response rate was measured by the number of correct responses emitted per session. Thirty pupils (15 second-graders and 15 third-graders) were randomly assigned to one of three experimental groups, based on matched triplets. One group worked under pupil-selected standards; the second group worked under standards selected by the experimenter with each pupil yoked to a member of the pupil-selected standards groups. Both groups participated in the calculation of their daily earnings. The third group served as a no-contingency control group. Baseline academic response rates on writing and math tasks were determined. During the experimental sessions reinforcement was provided in the form of points which were later traded for tangible rewards. The pupil-selected standards group showed a significantly greater number of correct responses in the writing and math tasks than the externally selected standards group.  相似文献

Behavioral procedures aimed at decreasing disruptiveness through increasing self-evaluative skills and programming generalization in a class of disruptive retarded children were examined. Phases of the study included: (a) baseline; (b) systematic feedback; (c) a token economy; (d) matching of teacher's ratings by students; (e) four fading phases during which progressively fewer students were required to match the teacher; (f) self-evaluation during which each student received the amount of points self-allotted regardless of teacher's ratings; (g) doubling of point costs of back-up reinforcers ("Inflation"); (h) complete removal of back-up reinforcers ("Points Only"); and (i) return to baseline conditions. The class was observed 5 days per week dueing a morning experimental period and several times per week in the afternoon as a measure of generalization. Additional measures of generalization included days when the token program was not in effect ("Off Days") and when the class was taught by a substitute teacher. Behavior was recorded according to an interval sampling observational code. The results showed that systematic feedback was effective in significantly reducing disruptiveness with even greater reductions resulting from the token program and the subsequent matching and fading phases. Decreased levels of disruptiveness were maintained throughout self-evaluation and the phases which followed. Decreased levels of disruption also generalized to afternoon sessions, to days when the experimental procedures were not in effect, and to self-evaluate, the class initially matched the teacher's ratings with about 50% accuracy. This gradually increased to consistently above 90% during the latter phases. The study demonstrated that retarded children can learn to accurately observe and veridically evaluate their own behavior, and that this has beneficial effects in terms of decreased disruptiveness.  相似文献

Behavior modification procedures have typically been used to eliminate discipline problems in the classroom through reinforcement of nondisruptive behavior. This report demonstrates an alternative approach whereby discipline problems are eliminated by reinforcing relevant academic skills. Five fifth-grade boys, identified by their teacher as discipline problems, were observed. The teacher conducted 15-min performance sessions in her reading class during which written academic performance and disruptive behavior were recorded. These measures indicated that the boys' average level of disruption was 34%, while their reading performance was below 50%. When systematic token reinforcement was applied to reading performance only, the rate of disruption fell drastically, and reading performance increased. When the reinforcement procedure was withdrawn, disruption again rose, and reading performance declined. The reinstatement of reinforcement doubled reading performance and eliminated disruption.  相似文献

Six nonstressful personality instruments were concurrently validated using respondent and close friend ratings on specific scale dimensions. Tests were administered to 203 predominantly Caucasian college students. Prior to testing, the individual and a close friend through self-ratings and ratings of the respondents had estimated the strengths of the tested personality Variables on a seven-point scale. The definitions of the various personality dimensions were taken from publisher's manuals. An estimated whole test validity was obtained by an average of the individual scale validities using a conversion of Pearson's r to z'. Significant differences among and between subtest validities were found by ANOVA. All "self-rating" validities were significant (.001), with two of these self-rating validities significantly different (.01) than the other four tests. Only two "other-rating" validities were significant. All six tests appeared to be valid for college population use From preliminary analysis, counselees could rate themselves accurately on most test measures. In some cases self-ratings might be used in lieu of giving the test.  相似文献

Although much is known about techniques for teaching elementary pupils in the classroom, no procedures have been consistently effective in training teachers to use these techniques. In the present study, six teacher trainees were observed individually and trained sequentially to use a variety of teaching skills: praise for academic responses, praise for appropriate classroom behavior, correction procedures for incorrect academic responses, and token fines. These skills were examined under four conditions: (1) baseline sessions were taught by the trainees before any instructions on the use of the teaching skills. (2) Instruction sessions were taught by the trainees after they were given instructions describing the use of several teaching skills. (3) During each Imposed-Package session, the trainees received modelling, verbal feedback, graphic feedback, and grade and quiz contingencies on their use of a particular teaching skill. (4) During each Self-Selected Package session, a grade contingency was in effect with the trainees choosing the components (modelling, verbal feedback, graphic feedback, quiz contingency) they wanted included in their training package for a particular skill. The effects of instructions were quite varied. Large increases on three of the four skills occurred with one trainee; almost no changes occurred with another trainee; and changes with the remaining four trainees fell within these extremes. The Imposed and Self-Selected Packages reliably increased the use of teaching skills, including those skills for which instructions had not been effective. The Self-Selected Package was considered to be as effective as the Imposed Package, since the time required for training a teaching skill varied from two to nine sessions with both packages. Under the Self-Selected Package, the trainees chose from modelling, verbal feedback, and graphic feedback, but none chose the quiz contingency. Questionnaire data collected after training showed that all six trainees preferred the Self-Selected Package to the Imposed Package. The effectiveness of the Self-Selected Package, together with the trainees' preference for it, suggests that it may be desirable for teacher training programs to specify the teaching skills, arrange a contingency for performance, and allow trainees to choose which additional components are to be used in each training session.  相似文献

An inexpensive, easily managed token economy was used in a normal classroom for one academic year, and data were collected for the entire academic performance in spelling, language, handwriting, and math for that year. During a baseline period, assignment completion was variable. The introduction of a token economy with a point exchange every five days increased assignment completion and decreased variability of performance. An application of a token economy that had a point exchange averaging four days was accompanied by an assignment completion rate that approximated 100%. A reinforcement contingency for which quiet behavior rather than for assignment completion was eased quiet behavior was accompanied by a marked diminution of assignment completion. A reintroduction of the token reinforcement for assignment completion system increased assignment completion again.  相似文献

An observational technique for reliably estimating the per cent of time a student engages in appropriate and inappropriate classroom behavior is described. The regular classroom teacher can utilize the procedure without deviating from regular routine, and the obtained data can serve as a basis for dispensing token reinforcement.  相似文献

This study focused on the assessment of impulsivity in nonreferred school-aged children. Children had been participants since infancy in the Bloomington Longitudinal Study. Individual differences in impulsivity were assessed in the laboratory when children were 6 (44 boys, 36 girls) and 8 (50 boys, 39 girls) years of age. Impulsivity constructs derived from these assessments were related to parent and teacher ratings of externalizing problems across the school-age period (ages 7–10) and to parent and self-ratings of these outcomes across adolescence (ages 14–17). Consistent with prior research, individual measures of impulsivity factor-analyzed into subdimensions reflecting children's executive control capabilities, delay of gratification, and ability or willingness to sustain attention and compliance during work tasks. Children's performance on the main interactive task index, inhibitory control, showed a signficant level of stability between ages 6 and 8. During the school-age years, children who performed impulsively on the laboratory measures were perceived by mothers and by teachers as more impulsive, inattentive, and overactive than others, affirming the external validity of the impulsivity constructs. Finally, impulsive behavior in the laboratory at ages 6 and 8 predicted maternal and self-ratings of externalizing problem behavior across adolescence, supporting the longterm predictive value of the laboratory-derived impulsivity measures.  相似文献
