Discrimination learning of delinquent boys as a function of reinforcement contingency and delinquent subtype

Previous research has demonstrated the effectiveness of contingency management as a means of behavioral resocialization with delinquent boys on an individual basis. The present study was designed to examine and clarify systematically the reinforcement parameters that underlie the male delinquent's response to verbal and token reward and/or punishment. The principal findings of the study were: (1) Neurotic subjects performed at the highest level for punishment, at the lowest level for reward, and at an intermediate level for a combination of reward and punishment, regardless of verbal or token contingency modality. (2) Psychopathic subjects performed best for the joint verbal reward and punishment contingency, but they did not learn over trials for the joint token reward and punishment contingency. Their performance was undifferentiated at asymptote under the separate verbal and token reward or punishment contingencies. (3) Neurotic subjects performed at a significantly higher level than did psychopathic subjects for verbal and token punishment, while psychopathic subjects performed at a significantly higher level than neutric subjects for verbal and token reward.The authors wish to thank the staff and students of the Lookout Mountain School for Boys and the Golden Gate Youth Camp at Golden, Colorado, for their cooperation in this study.

The influence of a model's reinforcement contingency and affective response on children's perceptions of the model

Following their observation of a videotaped model, boys and girls were asked to rate various characteristics of that model. In each of two experiments, the subjects were 90 primary grade children. The model's reinforcement (reward, punishment, or no consequences) and affective response (positive, neutral, or negative) constituted the independent variables. In both experiments, children who observed an affectively neutral model receive punishment, perceived his affective state as more negative than children who observed this model receive reward or no consequences. The converse attribution (i.e., inferring consequences based on depicted model affect) did not obtain. Also, data from both experiments supported the conclusions that (a) the punished model was less attractive than no-consequences and rewarded models, and (b) the model was perceived as less competent when he demonstrated negative affect or received punishment.     

Asymmetric attributions for compliance: Reward vs punishment

It was proposed that people attribute an individual's behavior more to internal factors when that individual's actions are influenced by reward than when those actions are influenced by punishment. Previous research has failed to control for the power of reward versus punishment which, in effect, creates a confounding of behavioral base rates (consensus) with the reward-punishment manipulation. The current research created reward and punishment contingencies that were equal in their base rates for producing a compliant response. In Experiment 1, subjects (n = 63) who produced the base-rate data also made attributions regarding a compliant target person. The results supported the reward-punishment attributional asymmetry hypothesis in that the target person was held more responsible for his actions in the reward than in the punishment conditions. A second experiment (n = 72) provided some attributors with information regarding base rates for compliance and measured perceived base rates for compliance. Knowledge of the base rates for compliance eliminated the reward-punishment attributional asymmetry phenomenon. Subjects not provided with such knowledge erroneously assumed different base rates for reward and punishment and maintained the perception of reward-punishment attributional asymmetry. Using subjects' estimates of base rate for compliance as a covariate eliminated the attributional asymmetry effect. It is suggested that erroneous base-rate assumptions mediate the attributional asymmetry phenomenon.     

Underlying processes in the poor response inhibition of children with Attention-Deficit/Hyperactivity Disorder

This study evaluated the effects of reward, punishment, and reward + punishment on the impulsive responses of ADHD children. The impulsive responses of ADHD and normal control boys (30 per group) were compared during performance of a go/no-go task, administered under reward-only, punishment-only, and reward + punishment conditions. When differences in aggression, anxiety, and IQ between these groups were controlled for, results indicated that the impulsivity levels of the ADHD group were higher than the control group in all three reinforcement conditions. Also, the ADHD group was more impulsive in the reward + punishment condition, compared to the reward-only and punishment-only conditions, and there was no difference between the reward-only and punishment-only conditions. The control groups showed no difference across the three reinforcement conditions. These findings raise the possibility that the poor response inhibition of ADHD children may be related to both a generalized inhibitory deficit and a response modulation deficit.     

The Ecological Veracity of the Self-Report

Sixty-five fourth- and fifth-grade boys were run in a two-choice discrimination learning task for punishment, high or low value reinforcement, or the combination of punishment with high or low value reinforcement. A significant main effect of reinforcement revealed that only Ss in the punishment group showed significant evidence of learning. The results were discussed as possibly being due to the distraction caused by tangible reinforcement; although, an alternative explanation was offered on the basis of previous findings that males perform better for punishment than for reward.     

How brain arousal systems determine different temperament types and the major dimensions of personality

Theory and research is described which led to the hypothesis that the choleric (E+N+) and melancholic (E−N+) temperaments are determined by differences in thalamocortical inhibition of brain-stem processes. An opportunity to test this hypothesis was provided by the recent discovery of 4, 7, and 10 Hz response waves confounded in EEG averaged evoked potentials [Robinson, D. L. (1999b). The technical, neurological, and psychological significance of ‘alpha’ ‘theta’ and ‘delta’ waves confounded in EEG evoked potentials: 1. A study of peak latencies. Electroencephalography and Clinical Neurophysiology, 110, 1427–1434; (2000). The technical neurological, and psychological significance of ‘alpha’, ‘delta’, and ‘theta’ waves confounded in EEG evoked potentials: A study of peak amplitudes. Personality and Individual Differences, 28, 673–693]. These responses are attributed to the brain-stem, limbic, and thalamocortical arousal systems, respectively, and in the cited reports principal components analysis of data obtained from 93 participants confirmed the existence of predicted excitatory and inhibitory relationships. ANOVA was used in the present study to test the further prediction that there should be strong inhibition of the 4 Hz system by the 10 Hz system in melancholics (E−N+) and weak inhibition of the 4 Hz system in cholerics (E+N+), with median inhibition predicted for the other temperament types. There was a large and statistically significant difference between the mean scores on the PCA inhibition factor obtained for the temperament groups, with temperament defined in terms of high and low EPQ extraversion (E) and neuroticism (N) scores. The significance of these results is discussed with reference to fundamental questions raised by Pavlov's pioneering research but left unanswered for the best part of a century. Implications for the future conduct of personality research are also considered.     

Sex differences in the neural underpinnings of social and monetary incentive processing during adolescence

The brain’s reward system undergoes major changes during adolescence, and an increased reactivity to social and nonsocial incentives has been described as a typical feature during this transitional period. Little is known whether there are sex differences in the brain’s responsiveness to social or monetary incentives during adolescence. The aim of this event-related potential (ERP) study was to compare the neurophysiological underpinnings of monetary and social incentive processing in adolescent boys versus girls. During ERP recording, 38 adolescents (21 females, 17 males; 13–18 years) completed an incentive delay task comprising (a) a reward versus punishment condition and (b) social versus monetary incentives. The stimulus-preceding negativity (SPN) was recorded during anticipation of reward and punishment, and the feedback P3 (fP3) along with the feedback-related negativity (FRN) after reward/punishment delivery. During anticipation of social punishment, adolescent boys compared with girls exhibited a reduced SPN. After delivery, male adolescents exhibited higher fP3 amplitudes to monetary compared with social incentives, whereas fP3 amplitudes in girls were comparable across incentive types. Moreover, whereas in boys fP3 responses were higher in rewards than in punishment trials, no such difference was evident in girls. The results indicate that adolescent boys show a reduced neural responsivity in the prospect of social punishment. Moreover, the findings imply that, once the incentive is obtained, adolescent boys attribute a relatively enhanced motivational significance to monetary incentives and show a relative hyposensitivity to punishment. The findings might contribute to our understanding of sex-specific vulnerabilities to problem behaviors related to incentive processing during adolescence.     

Reward sensitivity and substance abuse in middle school and high school students

In this study, the authors investigated the relation between reward and punishment sensitivity and adolescent substance use. The sample (N = 216; 130 girls, 85 boys) was drawn from high school and middle school students enrolled in a Midwestern suburban school district. Participants completed a substance use questionnaire and the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (R. Torrubia, C. Avila, J. Molto, & X. Caseras, 2001). For 13 of 15 types of substance abuse, students with high reward sensitivity and low punishment sensitivity showed the highest levels of use. This finding supports the hypothesis of an interaction effect between reward sensitivity and punishment sensitivity and suggests that individuals who are high in reward sensitivity but low in sensitivity to punishment may be at a higher risk for substance abuse.

Arithmetic achievement as a function of introversion-extraversion and teacher-presented reward and punishment

Following Eysenck (1967), Gray (1973) and Wakefield (1979), it was hypothesized that the arithmetic achievement of extraverts would be better than introverts in those classrooms in which teacher-presented rewards predominated, and the arithmetic achievement of introverts would be better than extraverts in those classrooms in which teacher-presented punishment predominated. Five classrooms were rank-ordered according to their ratios of teacher-presented reward to teacher-presented punishment. A total of 101 fourth and fifth grade students from the five classrooms were then administered the Junior Eysenck Personality Questionnaire (JEPQ) and an arithmetic pretest. Subsequent to 40 school days, the students were administered the arithmetic posttest. Partialling out arithmetic pretest scores, lie scale scores from the JEPQ, and total arithmetic raw scores from the Comprehensive Test of Basic Skills (CTBS), regression analysis of arithmetic posttest scores with the interaction of extraversion scores from the JEPQ and classroom rank-order of the ratio of teacher-presented reward to teacher-presented punishment yielded significant results supporting the hypothesis. Additional analysis indicated the presence of non-hypothesized interactions of the Psychoticism and Neuroticism scales of the JEPQ with reward-punishment and extraversion.     

Memory retrieval and discrimination learning

A better reinforcement schedule may be associated with one exteroceptive stimulus (S+) than with another exteroceptive stimulus (S−). While all theories agree that performance in such discrimination tasks is affected by the reinforcement schedules associated with the exteroceptive S+ and S− cues, some theories suggest that performance is also affected by the reinforcement schedule associated with interoceptive reward produced cues. The two experiments reported here were concerned with identifying the conditions under which the interoceptive cues produced by nonreward come to affect performance. According to one hypothesis, such cues will acquire control over approach responding if animals make an approach response in their presence, but not otherwise. According to the memory hypothesis, the memory of nonreinforcement will become a signal for reinforcement, thus invigorating performance, if it is retrieved on a rewarded trial. In two experiments, two groups made strong approach responses to the nonreinforced cues on S− trials, but the memory of nonreward was better retrieved on a subsequent rewarded trial in one group than in the other. Subsequently, both groups were extinguished. The extinction findings support the memory view.     

Relationships between leader reward and punishment behavior and subordinate attitudes,perceptions, and behaviors: A meta-analytic review of existing and new research

Despite decades of research on the relationships between leader reward and punishment behaviors and employee attitudes, perceptions, and performance, no comprehensive examination of these relationships has been reported in the literature. This paper reports the results of two studies that address this issue. In the first study, data from 20 new samples were gathered on the relationships between leader reward and punishment behaviors and some criterion variables that have not been examined extensively in previous research. In the second study, a meta-analytic review was conducted incorporating both the new and existing research in order to provide estimates of the bivariate relationships between these leader behaviors and a variety of employee criterion variables across 78 studies containing 118 independent samples. Results of regression analyses designed to control for the effects of the other leader behaviors showed that: (a) the relationships between leader reward and punishment behaviors and employee attitudes, perceptions, and behaviors were more functional when the rewards or punishments were administered contingently than when they were administered non-contingently, and (b) these leader reward and punishment behaviors were strongly related to two variables (employees’ perceptions of justice and role ambiguity) that were expected to be key mediators of the relationships between these leader behaviors and the employee criterion variables. In addition, meta-analytic evidence from longitudinal studies suggested that the same leader behavior can be a cause of some employee criterion variables, and a consequence of others. Implications of these findings for future research in the area are discussed.     

奖惩对行为抑制能力和自主生理活动影响的时效性

将45名被试随机分配为奖励组、惩罚组和对照组, 实验进程按时间发展过程被分为五阶段, 采用停止信号任务探讨奖惩刺激对行为抑制能力和自主生理活动影响的时效性。结果显示：奖惩刺激对行为反应时和抑制失败率影响仅在第二、三阶段差异显著, 对心率影响的显著差异在第三阶段结束、而对皮电和指温影响的显著差异仍持续到第五阶段。结果表明：奖惩刺激对行为的抑制作用具有时效性, 有效时间内表现为仅奖励能提高行为抑制能力; 奖惩刺激对心率的影响具有时效性, 但对其它生理指标的影响则未显示出时效性。     

Effects of Reward and Coercion for Transgression Compliance on Judgments of Responsibility and Recommended Punishment

Previous research ( Greitemeyer & Weiner, 2003 ) has demonstrated that compliance to commit a transgression for an anticipated reward as opposed to an anticipated punishment results in greater inferences of personal responsibility. The present studies extend these findings to a courtroom context in which punishment decisions are made. In Study 1, a nurse who administered a non-approved drug was perceived as more responsible; and more severe punishment decisions were recommended, given compliance for an offered reward relative to a threatened punishment. These findings subsequently were replicated while varying the consequences of the drug administration (Study 2) and employing an antisocial scenario (Study 3). Legal theory, field theory, and prospect theory are discussed as possible explanations for these phenomena.     

The contribution of “cool” and “hot” components of decision-making in adolescence: Implications for developmental psychopathology

Impairments in either “cool” or “hot” processes may represent two pathways to deficient decision-making. Whereas cool processes are associated with cognitive and rational decisions, hot processes are associated with emotional, affective, and visceral processes. In this study, 168 boys were administered a card-playing task at ages 13 and 14 years to assess response perseveration. This task was designed to initially reward playing and gradually associate playing with punishment. Measures of subjective ordering (cool processes) and neuroticism (hot processes) at age 13 years were used to examine how these individual characteristics relate to perseveration over time. A decrease in perseveration from age 13 to 14 was associated with cool processes whereas hot processes were associated with response perseveration only over time. A complementary but simultaneous assessment of cool and hot processes, such as neuropsychological and personality tests, could facilitate treatment planning of children with behavioral problems.     

Children’s implicit and explicit gender stereotypes about mathematics and reading ability

Study objectives were to clarify children’s gender-based implicit and explicit mathematics and reading stereotypes, and to determine if implicit and explicit measures were related or represented distinct constructs. One hundred and fifty-six boys and girls (mean age 11.3 years) from six elementary schools completed math or reading stereotype measures. Results for the implicit measures showed that children believed their own gender was superior in mathematics ability, and that girls but not boys believed that girls were better in reading. Explicit measures revealed that girls but not boys believed they were superior at math, and that girls and boys believed girls were better readers than boys. Implicit and explicit measures were not related. Results are discussed in relation to previous studies on children’s mathematics and reading gender stereotypes and large scale tests of mathematics and reading achievement. Educational and research implications are discussed.     

Sensitivity to reward and punishment in major depressive disorder: Effects of rumination and of single versus multiple experiences

In the current study, we examined the postulation that rumination makes it difficult for depressed individuals to learn the exact probability that different stimuli will be associated with punishment. To do so, we induced rumination or distraction in depressed and never-depressed participants and then measured punishment and reward sensitivity with a probabilistic selection task. In this task, participants first learn the probability that different stimuli will be associated with reward and punishment. During a subsequent test phase in which novel combinations of stimuli are presented, participants’ sensitivity to reward is tested by measuring their tendency to select the stimuli that were most highly rewarded during training, and their sensitivity to punishment is tested by measuring their tendency to not select the stimuli that were most highly punished during training. Compared with distraction, rumination led depressed participants to be less sensitive to the probability that stimuli will be associated with punishment and relatively less sensitive to punishment than reward. Never-depressed participants and depressed participants who were distracted from rumination were as sensitive to reward as they were to punishment. The effects of rumination on sensitivity to punishment may be a mechanism by which rumination can lead to maladaptive consequences.     

The effects of reward and punishment on reaction times and autonomic activity in hyperactive and normal children

The performance of hyperactive and control children was compared on a delayed reaction time task under three reinforcement conditions: reward, punishment, and reward plus punishment. Hyperactives had slower and more variable reaction times, suggesting an attentional deficit. Although each of the three reinforcement conditons was successful in improving reaction times for both subject groups, reward led to a significant increase in impulsive responses in the hyperactive children. Autonomic data revealed that reward also increased arousal to a greater extent than punishment or reward plus punishment. Although resting skin conductance was not different in the two groups of subjects, hyperactives produced fewer specific autonomic responses to signal stimuli.     

Sex stereotypes and responses to juvenile delinquency

On the basis of our current knowledge of sex stereotypes and their influence on judgments about women and men, two conflicting hypotheses about reactions to delinquent behavior by men and women, or by boys and girls, can be put forward. First, because crime is mainly masculine, responsibility for criminal behavior will be more strongly attributed to a boy's nature than to a girl's, thereby leading to more severe punishment for boys. Second, deviations from a stereotype lead to negative evaluations, and thus should lead to harsher punishment for girls. The first study described, based on a field experiment with 709 adolescent and 403 adult subjects, was conducted to determine whether different sanctions were applied to boys and girls who engaged in identical delinquent behavior. The results show that for boys, more severe punishment was preferred for aggressive behavior, and for girls, more punishment for noncriminal delinquent behavior. In a second study (N=43), it was hypothesized that these differences in sanctioning corresponded with the degree of perceived masculinity of the delinquent behavior. This hypothesis was confirmed. A model shows how sex stereotypes about delinquent behavior lead to sex-related difference in attributions, which in turn lead to differences in punishment.     

Mathematics Participation and Mathematics Achievement Across Secondary School: The Role of Gender

The present study investigated whether the relationship between mathematics participation and mathematics achievement is reciprocal for boys and girls. In Years 1, 2, 4 and 6 (US grades 7, 8, 10 and 12), we administered mathematics achievement tests to a cohort of 1,495 Flemish students and collected data on the number of classroom hours allocated to mathematics. A cross-lagged panel design was used to analyze the data. Evidence was found for a reciprocal relationship between mathematics participation and mathematics achievement, particularly in Years 4 and 6 (US grades 10 and 12). The results suggest that boys’ better performance in mathematics is related to their higher participation in math, whereas other factors—in addition to gender differences in math achievement—play a role in explaining why boys participate more in mathematics than girls.
