Effects of Deviant Child Behavior on Parental Distress and Alcohol Consumption in Laboratory Interactions

Levels of adult distress and ad lib alcohol consumption following interactions with child confederates were investigated in parents of children with no diagnosable psychiatric disorders. Sixty parents (20 married couples and 20 single mothers) interacted with boys trained to enact behaviors characteristic of either normal children or deviant children with externalizing behavior disorders — attention-deficit hyperactivity disorder (ADHD), conduct disorder (CD), and oppositional defiant disorder (ODD). Relative to the normal child role, interactions with deviant confederates were rated as significantly more unpleasant, resulted in feelings of role inadequacy, and produced significantly more anxiety, depression, and hostility. After the interactions, parents were given the opportunity to drink as much of their preferred alcoholic beverage as they desired while anticipating a second interaction with the same child. The participants consumed more alcohol following exposure to deviant as opposed to normal confederates.     

A method for the delivery of reinforcement during exercise

The purpose of this study was to develop an automated system for positively or negatively reinforcing subjects while they exercised on an electronically braked bicycle ergometer. The circuitry used to interface the subject’s pedal speed responses with the delivery of auditory reinforcement is presented, as well as a study designed to test the utility of the system. Twenty 18- to 25-year-old male subjects exercised on an electronically braked ergometer at a constant workload of 50 W for three 5-min blocks. During the first 5 min, subjects pedaled at their preferred rate, and during the next two 5-min blocks, they pedaled faster or slower than their baseline pedal speed to turn on a comedy tape for positive reinforcement, or turn off 90 dB of white noise for negative reinforcement. Circuits that interfaced the subject’s pedal response with the delivery of reinforcement are discussed in detail. Both positive and negative reinforcement increased the targeted pedaling rates, with no differences as a function of targeting increased or decreased pedal speed. This system could be used with various reinforcers, such as video and other audio equipment to increase exercise behavior.     

MULTIPLE PEER USE OF PIVOTAL RESPONSE TRAINING TO INCREASE SOCIAL BEHAVIORS OF CLASSMATES WITH AUTISM: RESULTS FROM TRAINED AND UNTRAINED PEERS

Two children with autism and 8 typical peers participated in a study designed to replicate an earlier finding of successful social-skills intervention for children with autism using peer-implemented pivotal response training (PRT) and to assess the effects of using multiple peer trainers on generalization of treatment effects. During training, peers were taught PRT strategies using didactic instruction, modeling, role playing, and feedback. After treatment, children with autism engaged in increased levels of social behavior.     

Fear of success: The influence of sex,sex-role identity,and components of masculinity

Phase I of this experiment was conducted to determine the nature of the relationship between fear of success and sex-role identity. Eighty female and 124 male subjects completed a measure of fear of success (the Sadd Fear of Success Scale, SFOS) and two sex-role scales (the Bem Sex Role Inventory, BSRI; and the Personal Attributes Questionnaire, PAQ). Subjects were subsequently classified by their responses to the BSRI and PAQ as either androgynous, masculine, feminine, or undifferentiated. The results indicated that androgynous and masculine individuals reported less fear of success than feminine or undifferentiated individuals, regardless of their sex. Subsequent analyses revealed that fear of success was more related to the absence of masculine traits than to the presence of feminine traits. Phase II of this investigation was conducted to determine whether a specific component of masculinity was related to the fear of success. The masculinity scales were factor analyzed and factor scores were regressed on the fear-of-success scores. Factor scores reflecting high self-confidence, decisiveness, analyticalness, and independence were related to low levels of fear of success; factor scores reflecting assertiveness, competitiveness, and opinionatedness were not related to the fear of success.     

The effect of transgressor's and victim's sex on children's punish-help judgments

The present investigation, expanding upon a study by Miller and McCann, sought to determine whether children's reactions to the perpetrators and victims of antisocial behavior are influenced by the sex of the individuals involved. Third- and fifth-grade children were asked their opinions of a series of stories in which one child (boy or girl) was described as having intentionally harmed another child (boy or girl). The results indicate that the relative importance that children attribute to punishing transgressors and helping victims is mediated by the sex composition of the transgressor-victim dyad.     

The biological function of Pavlovian conditioning: Learned inhibition of aggressive behavior in territorial fish

Following Pavlovian discrimination training, stimuli predicting the appearance of a territory intruder (an excitatory conditional stimulus, CS+) or the absence of that event (an inhibitory conditional stimulus, CS−) were presented to pairs of territorial male fish immediately before their first aggressive interaction. Pairmates that both received excitatory stimuli prior to the confrontation were significantly more aggressive than a control group which received the same training but which received neither a CS+ nor a CS− in the test. Pairmates in which both received a CS− were significantly less aggressive than the control group. In these three groups, no differences in aggression were observed between the individual members of a single pair. Two additional groups were composed of pairs whose members received different stimuli prior to the test. Although no differences were found between pairmates in the group in which one member received a pretest CS− while the other member received no stimulus presentation, large differences in aggressive behavior were obtained when one fish received a CS+ and its pairmate received a CS−. We discuss the behavioral ecology of terriorial behavior in fish and attempt to show the potential importance of these results in this naturalistic context. In addition, we discuss the implications of an ecological approach for causal analyses of inhibitory learning.     

The relationship of role-play assessment of children's social skills to multiple measures of social competence

The present investigation evaluated the relationship of role-play performance of children's social skills with multiple measures of social competence. Thirty-eight psychiatric inpatient children (ages 7–13 yrs) completed measures to assess role-play performance, knowledge of social skills, self-efficacy and self-reported social behavior in diverse situations. Overt social interaction was directly but unobtrusively assessed in the hospital as well. Multiple measures of social skills were also completed by hospital staff, parents and teachers. The results indicated that role-play performance correlated significantly with child knowledge and self-efficacy but not with overt social behavior or self-reported social behavior in diverse situations. Role-play performance generally did not correlate with measures completed by staff, parents and teachers. Yet measures completed by these informants did converge and also were useful in delineating diagnostic groups of children whose social behavior would be expected to be problematic. The implications of the results for the use of role-play tests to evaluate social skills and to discriminate clinical populations are discussed.     

Unilateral versus bilateral presentation methods in the reaction time paradigm

The use of bilateral presentation in lateralized tachistoscopic reaction time (RT) tasks has been precluded by problems of how to instruct the subject to respond to the left visual field (LVF) or right visual field (RVF) stimulus and by the necessity of fixation control with bilateral presentation. Schmuller and Goodman, 1979 and Schmuller and Goodman, 1980, Brain and Language, 11, 12–18) offered a method, applied to date only in recognition accuracy studies, which can overcome these problems. They used an “arrowhead pointer” at fixation. This instructs the subject as to which stimulus to report first and also controls fixation. We adapted the method to the RT paradigm by having subjects report only the stimulus indicated and applied it in a bilateral presentation version of the Object Naming Latency Task (W. F. McKeever & T. L. Jackson, 1979, Brain and Language, 7, 175–190). Fifty subjects received the unilateral task and 50 received the bilateral task. The bilateral task yielded right visual field superiority in 98% of the subjects and the magnitude of the superiority was over three times as large as in the unilateral task. Different sex × familial sinistrality × VHF interactions obtained on the tasks. Combining the advantages of reaction time and bilateral presentation methods may substantially increase the resolving power of lateralized tachistoscopic tasks.     

Alcohol,head injury,and neuropsychological function

Evidence is reviewed indicating that the extent of alcohol abuse alone cannot account for the neuropsychological deficits observed in alcoholics, and that alcohol abuse and head injury may interact in some patients to influence neuropsychological status. Alcohol abuse both increases the risk for head trauma and potentiates the resulting brain injury, which can lead to negative neuropsychological consequences. Clinicians involved in the treatment of addiction should assess patients for history of head injury, and neuropsychological deficits consequent to both head injury and ethanol. These deficits may limit patient ability to comply with addiction rehabilitation programs. Conversely, clinicians in acute care and rehabilitation of the sequelae of head trauma should routinely assess their patients for substance abuse, because such abuse can have a significant impact on recovery from brain injury.     

Properties of the recombination of one-dimensional motion signals into a pattern motion signal

We have examined the human ability to determine the direction of movement of a variety of plaid patterns. The plaids were composed of two orthogonal sine-wave gratings. When the plaid components are of unequal spatial frequency or sometimes of unequal contrast, observers judge the direction of movement incorrectly. In terms of the two-stage model of Adelson and Movshon (1982), these errors may result from either a misjudgment in the perceived speeds of each of the components or a failure in the combination of one-dimensional-component movements into a coherent direction of motion of the two-dimensional plaid pattern, or both. A comparison of the perceived direction of motion of plaids with the relative perceived-speeds of the plaid component gratings suggests that both failures occur, but in different circumstances The relative perceived speed of the plaid components was measured with a spatial and a temporal forced-choice technique, the former leading to larger differences. Our results support the notion that the visual system decomposes a moving plaid into oriented components and subsequently recombines the component motions.
