高低行为激活系统个体在赌博任务下的决策模式

为考察不同行为激活系统/行为抑制系统下的个体在Iowa赌博任务反应模式下的决策行为,本研究采用人格问卷与行为实验相结合的方式,探讨了人格、冲动和行为决策间的关系。结果发现:(1)行为激活系统三个维度与行为决策存在显著负相关,行为激活系统低分组的IGT得分较高,行为激活系统高分组的IGT得分较低,而冲动特征与IGT得分相关不显著;(2)行为激活系统高、低分者在IGT任务上差异显著,且行为激活系统高分组者在收益-风险并存情境中表现出"即时收益优先"的决策模式。结果提示,在收益-风险并存情境中,高行为激活的人格特征者倾向风险决策模式。     

FULL AND ERRANT COACHING EFFECTS ON ASSIGNED ROLE LEADERLESS GROUP DISCUSSION PERFORMANCE

The effect of coaching on Leaderless Group Discussion Performance was examined. Thirty-six female undergraduate subjects participated in six-person assigned role leaderless group discussions. Trained observers evaluated performances in each discussion, which included two 5s from each of three coaching conditions. Ss in full coaching condition received extensive coaching on proper group discussion performance. 5s in the errant coaching condition received improper, but believable, coaching. 5s in the naive, or control, condition received no coaching. Results showed that 5s in the full coaching conditions were rated significantly higher than 5s in the errant or naive conditions. The results were discussed in the light of previous research.     

决策权力和社会角色对混合动机冲突决策的影响

以最后报价谈判问题为实验材料,考察了混合动机冲突情境中决策权力和社会角色的影响。结果表明:(1)决策权力对决策者的决定有显著影响。拥有分配权的决策者倾向于采取竞争策略,拥有要求权的决策者倾向于采取平均分配策略,拥有否决权的决策者倾向于采取合作策略。(2)社会角色对决策者的决定有显著影响。与陌生人角色相比,担任好朋友角色的决策者决定得到的点数明显地更低。     

OPERANT PROCEDURES AND THE COMATOSE PATIENT

Operant procedures were tested on three patients who had been in vegetative coma for 6 months, 10 months, and 38 months. A discrete trial procedure was used to test compliance to verbal requests for three behaviors for each patient, including lateral head movement or finger movement, eye focus or eye squeeze, and mouth movement. The design for each patient consisted of multiple baselines across three behaviors with a withdrawal phase and a reinstatement phase (ABAB) for one behavior. Baseline phases were followed by contingent music phases in which 15-second taped excerpts of patients' preferred music sounded immediately following the emission of targeted behaviors. The contingent music treatment affected all three behaviors for Patient 1, but was less effective for two out of three behaviors for the second and third patients who had been in coma for more extensive periods of time. Results are discussed in terms of the potential contributions of the use of operant assessment and treatment procedures in an area of medicine where they have not been used before.     

GROUP DECISION-MAKING AND THE RISKY SHIFT A TRANS-NATIONAL PERSPECTIVE

On admet généralement que le degré de risque pris au niveau de la décision est plus élevé lors d'une décision de groupe que lors d'un choix individuel antérieur. Un nouvel instrument (Exercise Kolomon) a été utilisé pour tester la valeur interculturelle de cette hypothèse dans cinq pays : Colombie, Curaçao, Angleterre, France et Japon. Les résultats révèlent bien certaines différences culturelles quant au degré de risque pris individuellement avant la discussion mais les décalages entre les stratégies individuelles et concertées ne reflètent aucun effet systématique attribuable à la culture. Ils ne montrent pas davantage de glissement méthodique dans le sens d'un accroissement du risque. Il semblerait donc que la simple information provenant de la connaissance du choix de ses partenaires soit insuffisante pour provoquer un décalage dans le sens d'une stratégie plus audacieuse. Il convient de prendre aussi en considération l'information émanant de la tâche elle-même.     

DISCUSSION: BEHAVIORAL PROCEDURES FOR TRAINING DIRECT CARE STAFF IN FACILITIES SERVING DEPENDENT POPULATIONS

Behavioral training techniques of direct care staff have helped institutions serving dependent populations to progress from custodial settings to therapeutic environments. Most of the recent literature on staff training has focused on contingency management procedures, especially feedback procedures. Long-term studies of these procedures suggest that individual verbal feedback on the performance of the staff member is the best assurance of maintenance of these procedures.     

CONTINGENT PAYMENT PROCEDURES FOR SMOKING REDUCTION AND CESSATION

We assessed the ability of a combined contingent reinforcement and intensive monitoring procedure to promote and sustain temporary smoking cessation among 34 hired research volunteers, and the ability of a smoking reduction test to predict the subsequent initiation of abstinence. During the 5-day cutdown test, subjects were paid from $0 to $6 per day depending on the extent of reduction from baseline CO levels. During the abstinence test, breath samples were obtained three times daily and subjects were paid $4 for each CO reading ≤11 ppm. Sixty-eight percent of subjects initiated abstinence. Of the breath samples collected during the abstinence test (91% of scheduled samples), 96.5% were ≤11 ppm and 80.5% were ≤8 ppm. Subjects who earned more money during the cutdown test were more likely to abstain (r = ?0.51, p < .001). Contingent reinforcement and intensive monitoring procedures appear to have usefulness for analog studies of smoking reduction and cessation.     

RECONCEPTUALIZING ISSUES THAT AFFECT WOMEN'S SEXUAL DECISION-MAKING AND SEXUAL FUNCTIONING

This paper addresses five existing societal myths and their underlying faulty assumptions about women's sexuality. The following myths are examined: (a) women possess adequate sexual knowledge to understand their sexual needs, (b) they know how to communicate about sex, (c) they engage in sex because they want to do so, (d) if they are sexually active, they enjoy sex, and (e) they use their knowledge of sex to protect themselves from sexually transmitted diseases and pregnancy. These myths need to be considered when conducting research and developing interventions designed to decrease women's sexual risk-taking. Research that assesses women's levels of factual sexual knowledge, comfort and skills discussing sexual information, and literacy is needed. The importance of examining ethnic, cultural, economic, religious, relationship factors, and psychological issues is discussed in order to encourage research relevant to women's sexual decision-making.     

COMPARISON OF ESTABLISHED AND INNOVATIVE WEIGHT-REDUCTION TREATMENT PROCEDURES1

A central component of a commonly used weight-loss procedure developed by Stuart (1967), which emphasizes situational engineering (SE), was compared to eating behavior control (EBC), a treatment employing reinforcement of changes in eating habits. A third treatment encouraged development of individuals' own applications of a model of self-control and attempted to provide effective feedback regarding progress toward weight-loss goals. This self-initiated treatment (SI) was designed to be less directive than many behavioral treatment packages and to be more realistic about the expectations of subjects and the actual eating habits of overweight and normalweight people. Following baseline, treatment lasted six weeks and followup lasted 16 weeks. While all treatments produced weight losses, EBC surpassed SE during treatment. SI losses during treatment did not differ from SE or EBC, but SI was the only group that lost weight throughout followup, indicating the possible utility of more subtle, less directive interventions than those that have often been associated with behavioral approaches. The results of SE question the applicability to clinical procedures of the external cue hypersensitivity theory of obesity (Schachter and Rodin, 1974), to which SE is closely related.     

SUPREME COURT DECIDES HIRING AND PLACEMENT PROCEDURES MUST BE VALID

The U.S. Supreme Court's decision in Griggs v. Duke Power Company (1971) will have important effects on industrial personnel practices that in time will be felt in government, schools, colleges, and other institutions and eventually will touch almost all Americans. In its decision the court admitted that tests are useful but stipulated that they must be valid or job related. The decision will do much to make qualification the all important factor in hiring and selection, and will tend to make race, religion, nationality, and sex irrelevant factors.     

PRODUCING GENERATIVE SENTENCE USAGE BY IMITATION AND REINFORCEMENT PROCEDURES1

Three retarded subjects and two developmentally normal toddlers were trained using imitation and reinforcement procedures to use correct sentences. The experimental task was to use sentences with correct subject-verb agreement to describe pictures that were presented to the subjects. Two classes of sentences were taught: those involving a plural subject that required the use of the verb “are” (for example, “the boys are running”) and those involving a singular subject that required the use of the verb “is” (for example, “the boy is running”). The basic design of the study involved multiple baselines for each class of sentences. Four of the subjects began to produce novel, untrained sentences of a particular type to generalization probe pictures when that particular class of sentence was currently being trained. Thus, the imitation and reinforcement procedures appeared to be functional in producing generative sentence usage for both types of sentences. One subject produced correct sentences to both singular and plural probe pictures when only “is” sentences had been taught. A reversal procedure and retraining phase indicated that for this subject, imitation and reinforcement procedures for training one class of sentence behavior seemed functional in producing generative responses of the other class of sentences.     

VALIDITY AND FAIRNESS OF SOME ALTERNATIVE EMPLOYEE SELECTION PROCEDURES1

Despite extensive evidence that tests are valid for employee selection, Federal Guidelines have urged employers to seek alternative selection procedures that are equally valid but have less adverse impact on minorities. Research on the validity, adverse impact and fairness of eight categories of alternatives was reviewed. Feasibility of operational use of each type of alternative in an employment setting was also discussed. Only biodata and peer evaluation were supported as having validities substantially equal to those for standardized tests. Previous reviews and more recent research indicated that interviews, self-assessments, reference checks, academic achievement, expert judgment and projective techniques had levels of validity generally below those reported for tests. Data, where available, offered no clear indication that any of the alternatives met the criterion of having equal validity with less adverse impact. Results are discussed and several additional promising alternatives are described.     

ORGANIZATIONAL PERFORMANCE AND ORGANIZATIONAL LEVEL TRAINING AND SUPPORT

The present study uses both objective and survey data to examine relations among retail sales training, organizational support, and store performance and to examine whether training interacts with organizational support to predict store performance. The study is unique in that it presents an example of the analysis of the relationship between organizational level measures of training and performance, as opposed to more traditional individual level measures. Archival data in a correlational design were analyzed for 62 stores belonging to the same international merchandising firm. Two measures of training and two measures of support were used to predict two measures of store performance. Results indicated that training and organizational support were significantly correlated with both measures of store performance, although the relationship between training and organizational performance was stronger. In contrast to predictions, there were no significant interactions between the training and support variables.     

ITEM GENERATION PROCEDURES AND BACKGROUND DATA SCALES: IMPLICATIONS FOR CONSTRUCT AND CRITERION-RELATED VALIDITY

Background data measures are one of the best predictors of job performance. Nonetheless, questions have been raised about their content and construct validity. The present effort describes a set of procedures for developing construct and content valid background data items. Data gathered in seven field studies and six laboratory studies are presented bearing on the reliability and validity of the measures constructed using these item generation procedures. Findings in these studies indicate that construct-based item generation procedures yield reliable scales evidencing both content and construct validity. Furthermore, these scales are capable of predicting performance in a variety of settings. Theoretical and practical implications of these findings for the development and validation of background data measures are discussed.
