THE USE OF GOAL SETTING AND CONTINGENCY CONTRACTING FOR IMPROVING CHILDREN'S HOMEWORK PERFORMANCE

We examined the effects of goal setting and contingency contracting on children's homework performance. Subjects were 4 parent—child dyads in which the child exhibited substantial homework problems. Using a combination of multiple baseline and reversal (ABAB) designs, goal setting and contingency contracting produced significant improvements in children's homework accuracy. Two of the 4 subjects showed substantial improvements in on-task behavior. Consumer satisfaction with the procedures was supported by parent ratings conducted posttreatment.     

CONTINGENCY CONTRACTING WITH DELINQUENTS: EFFECTS OF A BRIEF TRAINING MANUAL ON STAFF CONTRACT NEGOTIATION AND WRITING SKILLS

A brief training manual was developed for the purpose of teaching child-care workers to contingency contract with delinquent youths living in residential care facilities. The manual was designed to require minimal supplementary training by a professional. In Experiment 1 a multiple baseline design was used to assess the effect of the manual on 4 child-care workers' contract negotiation and writing behaviors. Experiment 2 consisted of four A-B systematic replications. Behaviors were assessed within the context of analogue training simulations and generalization tests with delinquent youths. Results from the analogue simulations indicated that the manual was successful in increasing both types of behaviors to a level of proficiency that equaled or surpassed that of behaviorally trained graduate students, and results from the generalization tests indicated that the child-care workers were able to apply their newly acquired contracting skills with delinquent youths. Procedural reliability varied across child-care workers, but was usually high.     

TREATING OVERWEIGHT CHILDREN THROUGH PARENTAL TRAINING AND CONTINGENCY CONTRACTING1

Fifteen overweight girls aged 5 to 11 yr were randomly assigned to one of two weight-reduction treatments: response-cost plus reinforcement, response-cost only, or a no-treatment control group. In the response-cost plus reinforcement group, parents contracted to facilitate their child's weight loss by carrying out reinforcement and stimulus control techniques, completing weekly charts and graphs, and encouraging their child to exercise. The response-cost only group parents did not contract to reinforce their child's performance. The response-cost program applied to both experimental groups was conducted in weekly meetings in which parents lost previously deposited sums of money. Twenty-five per cent was deducted for missing the weekly meeting, 25% for failing to fill out charts and graphs, and 50% if their child failed to meet her specified weekly weight-loss goal. At the end of the 12-week treatment period, both experimental groups had lost significantly more weight than the control group. After an eight-week, no-contact follow-up, some of the lost weight was regained. The response-cost plus reinforcement group was still significantly below the controls. The response-cost group just missed significance. A 31-week, no-contact follow-up failed to show a treatment effect, but did show a trend towards slower weight gain by the response-cost plus reinforcement group.     

THE EFFECTS OF DIFFERENT REINFORCEMENT CONDITIONS ON THE TEST PERFORMANCE OF MULTIHANDICAPPED DEAF CHILDREN1

The present study explored the effects of different reinforcement conditions on the number of correct responses on the Raven Progressive Matrices. Four groups of 11- to 18-year-old multihandicapped deaf children matched on the basis of mean age and pretest scores were used. The groups were randomly assigned to any of four posttest conditions: end-of-session reinforcement, noncontingent reinforcement, delayed reinforcement, and immediate reinforcement. The mean posttest score of subjects tested under the immediate-reinforcement condition was significantly higher than that of any other group. No significant differences were observed between the mean posttest scores of the three other groups. The practical implications of using reinforcement procedures for testing purposes are discussed.     

SHORT- AND LONG-TERM EFFECTS OF CONTINGENCY MANAGED INSTRUCTION ON LOW,MEDIUM, AND HIGH GPA STUDENTS1

Undergraduate students had been assigned to a contingency managed course or a conventional lecture course (Du Nann and Fernald, Journal of Applied Behavior Analysis, 1976, 9 , 373–374). Two years later, some 35% (N = 86) of the original classes responded to a letter offering them $2.00 to participate in a study of their educational experiences. These students completed a multiple-choice test on material from the course, and answered questions about activities and attitudes that might have been affected by the experience in Introductory Psychology. In the contingency management course 2 yr past, students were tested each week on a chapter of textbook material with 10-item multiple-choice quizzes. The course employed a modified “Doomsday Contingency”, requiring each student to achieve 80% mastery on one of the four weekly quizzes or drop the course. Quizzes were given in small groups and scored individually, while the student stood near, by an undergraduate proctor assigned to that group. The proctor was asked to show interest in the students' quiz performances, help clear up difficult areas, and develop a friendly working relationship with each student. While many students passed the quiz on the first attempt, others were given individual tutoring, so that no one was in fact forced to drop the course. In addition to the weekly quiz assignment, students in the contingency managed group were asked to attend one lecture each week. While the contingency management course procedures had much in common with PSI (Keller, Journal of Applied Behavior Analysis, 1968, 1 , 79–89), several departures made them unique. First, self-pacing was curtailed because students were required to master one unit per week or drop the course. Second, proctors met with students in small groups, usually giving individual tutoring only to those students who did not pass the quiz on the first attempt. Finally, students were asked to attend one lecture per week. Students in the conventional lecture group were not asked to pass weekly quizzes, but instead attended three 50-min lectures each week. Two of these lectures followed the textbook material closely, while the third, which was also attended by students from the contingency management course, covered material only indirectly related to the text. This partition of lecture content allowed material to be similar across the two instructional groups. Although students in the lecture condition were told they could obtain copies of the quizzes, few of them did so. Course grades were determined by scores on two 45-item multiple-choice hourly exams, each covering half the semester material (each worth 25%), and by a 90-item final exam, which served as a measure of short-term retention. Before analyzing the follow-up data, several characteristics of the returning students were compared to determine the comparability of the sample from the two original classes. Most important, both attrition and the current mean GPAs of students from the two classes were very similar. These considerations, and others, suggested there was no systematic sampling bias to confound comparisons of student performance. A 2 (contingency management versus traditional lecture) by 3 (high, medium, and low GPA) analysis of variance was computed on the course final-exam scores and the follow-up measures. Instructional procedure and GPA interacted on the final exam such that low and medium GPA students performed significantly better under contingency management, but there was no significant effect of instructional procedure with high GPA students. On the 2-yr retention measures, students from the contingency management course performed significantly (p < 0.01) better on items drawn from quizzes used in their original course, and marginally better (p < 0.10) on items drawn from the final exams, but no interactions with GPA appeared. Furthermore, instructional method produced no significant main effects or interaction with how many students became majors or minors in psychology, how many psychology courses were later taken, how many books in psychology were reported to have been read, or on students' evaluation of the interest and importance of psychology.     

THE EFFECTS OF PARTICIPATION AND GOAL DIFFICULTY ON PERFORMANCE

Previous research comparing the effects of assigned versus participatively set goals on performance were essentially tests of the null hypothesis in that goal difficulty level was not systematically manipulated. The present laboratory study investigated the effects of assigned versus participatively set goals, and the effects of varying goal difficulty level on an arithmetic task. Eighty-six college students were assigned to either a participative goal condition or one of three assigned goal conditions. In two of the assigned goal conditions participants were assigned goals equal to those set in the participative condition, the difference being that individuals in one group were assigned goals at random and those in the other group were assigned goals on the basis of their premeasure scores. Participants in the third assigned goal condition were randomly assigned a goal in the top quartile of the goals set participatively. As hypothesized, individuals with hard assigned goals had higher performance than peers with lower goals set in a participative manner. Contrary to modern organizational theory, individuals with participatively set goals did not have higher performance than those with assigned goals of equal difficulty. Personality traits were not found to moderate the effects of goal setting on performance.     

目标取向和工作经验对绩效的效应

通过两个样本调查,对目标取向和工作经验量表进行了结构检验,并探讨了目标取向和工作经验对个体绩效的效应模式。结果表明：学习目标取向和工作经验定性成份与绩效间存在中等程度相关;在控制了人口统计学变量的效应后,学习目标取向对绩效具有显著的预测效应;工作经验定性成份与绩效间的关系受到学习目标取向缓冲,在学习目标取向低分组,工作经验定性成份对个体绩效更具预测力     

GENDER AND CULTURE INTERACTION EFFECTS ON SCHOLASTIC APTITUDE TEST PERFORMANCE: SOME ISRAELI FINDINGS

The major aim of this study was to assess the degree of interaction between gender and cultural group background in determining scholastic aptitude test attainment among college student candidates. The analyses were based on the college entrance aptitude test scores of 1778 Jewish and 1017 Arab student candidates applying for admission to a major Israeli university. A Manova of the subtest scores revealed significant main effects for both culture and gender and a significant gender × culture interaction effect. Separate Anovas for each of the individual subtests show significant gender × culture interaction effects for both the Mathematical and Figural Reasoning subtests, with a larger gender group differential - in favor of the males - among Jews than among Arabs. The interaction effect was attributed, in part, to two complementary culture-specific factors, namely: (a) the positive self-selection of Arab female college candidates of relatively high scholastic ability, thus serving to narrow the gender gap in the Arab group; (b) the varied opportunities for advanced technical training, enrichment and experience available mainly to Jewish males during their period of compulsorly military service, serving to enhance the gender gap in the Jewish group. In sum, the data suggest that culture may serve as an important moderator variable in determining the size of gender group differences in scholastic aptitude test attainment.     

EFFECTS OF ALTERNATIVE DELETION PATTERNS,BLANK CONDITIONS,AND SCORING SYSTEMS ON INTERMEDIATE LEVEL CLOZE TEST PERFORMANCE

The majority of cloze research has focused on a traditional test format whereby (1) deletions occur on an every‐nth word basis, (2) standard length blank spaces are provided, and (3) only exact word replacements of the original text receive credit. In this study, an analysis was made of the effects of selected deletion patterns (every‐nth versus total random), blank conditions (standard versus cued), and scoring modes (verbatim versus synonymic) on the cloze test performance of 64 sixth grade readers. Neither the deletion pattern nor blank condition main effects achieved significance; however, as expected, increased performance was observed for synonymic scoring. Most importantly, all first‐order interaction effects attained significance. In the total random/cued/ verbatim cloze format, context distances of less than four words generated correct responses as effectively as context distances of four, the equivalent of an every‐5th word deletion strategy. Further, this format exceeded all others in internal consistency and in its ranking of subjects' performance relative to their synonymic cloze test scores.     

照度和对比度对于视觉显示终端视觉功能的影响

本研究试图通过视觉显示终端的视觉功能研究,了解图象在荧光屏上的亮度对比度、荧光屏照度以及不同光源对于视觉功能的作用。图象在荧光屏上的亮度对比是影响阅读速度的重要因素,同时,荧光屏照度增加时,阅读速度降低。为了提高工作效率,可以提高图象在荧光屏上的亮度对比,也可以降低荧光屏照度。我们似乎可以推荐合适的荧光屏照度为50—200Lux。这时水平工作面照度是70—340Lux。     

工作记忆与领域知识在个体认知行为中的作用

新近研究表明,工作记忆和领域知识在个体认知行为上起了积极的作用,对二者关系的研究有三种观点：一是强调工作记忆或领域知识在认知行为中的单独作用;二是综合考察二者在个体认知行为中的不同作用;三是建立模型,阐述工作记忆和领域知识在认知行为中的作用。最后针对当前有关此方面的研究,探讨有关工作记忆和领域知识作用研究的发展趋势。

EFFECTS OF ACHIEVEMENT MOTIVES AND SEX ON WRESTLING ABILITY AND MOTOR PERFORMANCE

An earlier study of main effects of achievement motives on performance amongst boy wrestlers was repeated with girls. The 1970 Achievement Motives Scale of Gjesme and Nygård was administered to 29 girls, and subjects' scores were sampled for three different wrestling championships at a national level. Oxygen uptake, speed of movement, four muscular strength exercises, and serial performance of five wrestling holds were measured. As with males, success-oriented females performed better than indifferent-oriented subjects in wrestling championships. The former group performed also better than the latter in pull-ups, sit-ups, forward throw and 1/4 Nelson. In addition, success-oriented females performed better than those who were failure-oriented in pull-ups and sit-ups, although this was not the case in other tasks and championships. Indications of sex differences in the relationship between motivation and performance were found among subjects who aim for achievement and, at the same time, have a high motive for failure, i.e. those who were conflict-oriented. Motive patterns and sex influence some, but not all, of the responses measured in the different tasks. Suggestions for future systematic research on a task effect are discussed. In general, the data indicate that, among highly selected and high ability boys and girls who set a high value on goals of an activity, relationships between achievement motives and performance in that activity should emerge for both sexes. In addition, sex should modify motive-performance relationships.     

EFFECTS OF DELEGATED CHOICE ON PERFORMANCE

The delegation process has not been subjected to adequate scientific examination. This study examines the effects of delegated choice over scheduling of activities (ordering of events) and over selection of goals (degree of challenge). Subjects made financial predictions based upon accounting data as input. Prediction accuracy was the dependent measure. Interestingly, under some conditions, delegation of choice over scheduling activities backfired. There were initial positive effects, however, from delegating choice over the selection of goals. Clearly the aspect of the task being delegated appears important. One cannot assume allowing others choice over some aspects of the task will be associated with positive outcomes.     

不同干预方式、不同应激源对血压、心率的影响

探讨不同干预方式、不同应激源对血压、心率影响的差异。被试为本科生48人,采取干预方式、应激源、实验间期的三因素混合实验设计。干预方式为放松训练和预知,应激源为心算和恐怖影片。实验间期包括基线期、干预期、应激期、恢复期。实验的因变量为每个实验间期的血压和心率。结果显示,心算应激引起的血压和心率升高显著高于恐怖影片应激引起的血压和心率的升高;放松训练组和预知组其干预期的血压和心率值都低于基线期;干预方式和应激源在血压和心率两个指标上交互作用不显著。结果表明,与恐怖情绪引起的紧张相比较,智力操作紧张更容易影响血压和心率;放松训练和预知对于对抗应激时血压和心率升高都起到了一定的作用;不同干预方式对于不同性质的应激源作用没有差别。     

结构限制和信息干扰对双重作业绩效的影响

研究通过改变双重任务呈现的间隔时间来探讨结构限制与信息干扰对双重任务操作绩效的影响。实验结果表明：(1)两种作业呈现的间隔时间对双重任务操作绩效有明显的影响。间隔时间越大,双重任务的作业绩效越高。(2)信息干扰对双重任务的操作有明显的影响。信息干扰越大,双重任务的操作绩效越差。(3)两个作业呈现的间隔时间不同并不影响信息干扰对双重任务操作绩效的作用。根据实验结果,该研究提出了三因素假设：结构限制、信息干扰和资源竞争是影响双重任务操作绩效的三个主要因素。     

THE EFFECTS OF ON-SITE CHILD CARE ON EMPLOYEE ATTITUDES AND PERFORMANCE

Using a quasi-experimental posttest design, this study compared supervisor perceptions of performance and absenteeism and employee attitudes of 155 child care center users and waiting list employees. Although child care was not related to supervisor views of performance or absenteeism, employees were more likely to receive favorable appraisals if absenteeism was low. Child care had greatest impact on females and employees without a family buffer. Child care positively influenced users' attitudes toward managing work and child care responsibilities, and views on the attractiveness and administration of benefits. The greater the use of care across all dependents, the more favorable the attitudes. A "frustration effect" occurred involving the lowering of waiting list employees' perceptions of the attractiveness and fairness of child care. The study suggests that child care benefits are more likely to significantly effect employee attitudes and membership behaviors such as recruitment and retention than performance or absenteeism.     

SIDE EFFECTS OF THERAPEUTIC PUNISHMENT ON ACADEMIC PERFORMANCE AND EYE CONTACT

The effects of therapeutic punishment delivered following inappropriate behavior on the academic responding and eye-to-face contact of 2 persons with developmental handicaps was examined using a counterbalanced alternating treatment design. Each subject was sequentially taught by two therapists each day. While one of the therapists taught the subject, the second therapist stood in close proximity directly behind the subject. During baseline, neither therapist delivered punishment following inappropriate behavior. During the treatment condition, one of the therapists delivered all punishment regardless of whether she was teaching or standing behind the subject. The therapist who delivered all punishment for 1 subject did not deliver any punishment for the other subject. During the last condition, the therapist delivering all punishment was reversed for 1 of the subjects. The results indicated that the task being taught was mastered by each subject only when the therapist delivering punishment was teaching. Data collected also indicated that each subject made more eye-to-face contact when the therapist delivering all punishment was teaching. Although neither therapist had to deliver punishers often, punishment had to be administered less often when the therapist teaching the subject was also the therapist delivering punishment.     

EFFECTS OF INVENTED SPELLING AND DIRECT INSTRUCTION ON SPELLING PERFORMANCE OF SECOND-GRADE BOYS

Four second-grade boys, 2 rated by their classroom teacher as below average and 2 as above average in basic language skills, participated in a 16-week spelling investigation. The participants alternately received, in counterbalanced order, 5 weeks of an invented spelling approach that incorporated 15-min creative writing periods and 5 weeks of direct instruction that involved 15-min periods of guided practice on spelling word lists. At the end of 10 weeks, each condition was replicated for 3 additional weeks. Although direct instruction resulted in more targeted words spelled correctly, invented spelling resulted in more nontargeted words spelled correctly, higher preference ratings by children, and higher teacher ratings of the quality of 3 of the children's writing samples.
