Interventions With Juvenile Offenders: Strategies to Prevent Acting Out Behavior

In this article Moral Dilemma Discussion Groups, Just Communities, Positive Peer Culture and the EQUIP program are reviewed for their appropriateness for intervening with juvenile offenders in residential settings. The suitability of these interventions for diverse populations is also examined.     

Auditory generalization gradients for response latency in the monkey

Two monkeys were trained to press and hold a response key in the presence of a light and to release it at the onset of a pure tone. Initially, all responses with latencies shorter than 1 sec were reinforced without regard to the frequency of the pure tone, and the intensity of the pure tone that resulted in equal latencies at each frequency was determined. The second stage of the experiment consisted of discrimination training, during which releases to one pure-tone frequency (positive stimulus) were reinforced and releases to a second frequency (negative stimulus) were extinguished. Median latencies to the negative stimulus slowly increased as did the variability of the latency distribution for the negative stimulus. There was no evidence of a concurrent decrease in latencies to the positive stimulus indicative of behavioral contrast. The third part of the experiment consisted of determining maintained generalization gradients by increasing the number of nonreinforcement stimuli. The gradients that eventually resulted showed approximately equal latencies to all frequencies of the negative stimulus and shorter latencies to the positive stimulus frequency.     

Comparing the Defendant to Images of the Culprit: Interpreting Results of Mock Witness Filler‐Control Tests

Criminals are occasionally recorded on video committing a crime. At trial, jurors may be shown images of the culprit to determine if they match the defendant. However, several sources of bias may influence juror matching decisions. Also, even with clear video, the accuracy of defendant‐culprit matching can be relatively poor. To reduce these problems, we propose that defendant‐culprit matching be viewed as a type of forensic test. If conducted as a forensic test, defendant‐culprit matching can be improved by adding fillers and testing mock witnesses rather than the actual jurors. A Bayesian analysis of data from two experiments shows that a filler‐control test can be highly diagnostic, even when the decisions of mock witnesses are far from unanimous. However, when viewing conditions are poor, a filler‐control test may not provide much new information about whether the defendant matches the culprit. Copyright © 2017 John Wiley & Sons, Ltd.     

Rapid facial reactions to emotional facial expressions in typically developing children and children with autism spectrum disorder

Typical adults mimic facial expressions within 1000 ms, but adults with autism spectrum disorder (ASD) do not. These rapid facial reactions (RFRs) are associated with the development of social-emotional abilities. Such interpersonal matching may be caused by motor mirroring or emotional responses. Using facial electromyography (EMG), this study evaluated mechanisms underlying RFRs during childhood and examined possible impairment in children with ASD. Experiment 1 found RFRs to happy and angry faces (not fear faces) in 15 typically developing children from 7 to 12 years of age. RFRs of fear (not anger) in response to angry faces indicated an emotional mechanism. In 11 children (8-13 years of age) with ASD, Experiment 2 found undifferentiated RFRs to fear expressions and no consistent RFRs to happy or angry faces. However, as children with ASD aged, matching RFRs to happy faces increased significantly, suggesting the development of processes underlying matching RFRs during this period in ASD.     

A Debate on the Ethics of Aging: Does the Concept of Autonomy Provide a Sufficient Framework for Aging Policy?

This article presents a debate on the issue of autonomy in aging policy held at the 1994 annual meeting of the American Society on Aging held in San Francisco, California. Harry R. Moody, director of the Institute for Human Values in Aging at Hunter College, supports a reconceptualized notion of personal autonomy which focuses on issues of power, theory, and practice, and finds conflicts between autonomy and justice in the lived world of the elderly and disabled. In aging policy, he promotes an emphasis on social movements such as Hospice rather than on autonomy of individuals. He suggests alternatives to extreme paternalism or complete autonomy, such as a communicative ethics approach. Larry Polivka, director of the Florida Policy Exchange Center on Aging at the University of South Florida, affirms that policy for the aging and disabled should be based ona commitment to autonomy. He describes an integrated model for long-term care that places autonomy first and includes features of communicative ethics and the negotiated consent and virtues models of ethics.     

Racial bias in behavioral assessment of children's social skills

The social skills of 20 second- and sixth-grade students were assessed by 20 trained raters using the Social Skills Test for Children (SST-C). Rater and child characteristics were examined to determine whether differences in social skills ratings were due to the race of the rater or the race of the children being rated or due to the interactive effects of these characteristics, which would suggest racial bias in the ratings procedure. The results showed that the race of the rater did affect some behavioral observations. Black raters gave higher scores than white raters on four behavioral categories: response latency, appropriate assertion, effective assertion, and smiling. White raters gave higher scores for head position and gestures. The results of this study replicated earlier findings of significant differences in social skills ratings due to the race and age of the child being rated. The results also showed modest racial bias effects in that black and white raters scored black and white children differentially on two behavioral categories: overall skill ratings and smiling. These results suggested that most behavioral categories of the SST-C were not systematically affected by racial bias. However, the most subjective rating, overall skill, did evidence racial bias effects. This finding is consistent with previous data showing that subjective ratings may be most affected by racial bias.     

Factors affecting the social validity of a role-play test of children's social skills

The social validity of a role-play test of children's social skills, the Social Skills Test for Children (SST-C), was evaluated by 63 subjects (33 adults and 30 children) who subjectively judged the quality of three children's role-play performances. The three children were selected as having high, medium, or low social skill based upon their performance on the SST-C. Assessment of the effects of subject characteristics upon judgments of social skill suggested that similarities in age and race between the subjects and the three children tended to diminish perceived differences in social skill among the three children. It was concluded that the social validity of the role-play test was supported only if the persons evaluating social behavior were dissimilar in age and racial characteristics from the persons who were being evaluated.     

Factors influencing the salience of temporal cues in the discrimination of synthetic Japanese monkey (Macaca fuscata) coo calls

If temporal position of a frequency inflection is the most salient communication cue in Japanese macaque smooth early and smooth late high coos, then macaques should perceive coos differing only along the early-late dimension as belonging to different classes. The perceived similarity of synthetic coos and temporally reversed variants were evaluated, using multidimensional scaling of macaque discrimination latencies. Original calls and calls temporally reversed in the frequency domain could be discriminated if the peak was near a call endpoint but not if the frequency peak in the original call was near the coo midpoint. Perceived similarity of such calls was inversely related to the amount of frequency modulation. Temporal reversals of amplitude contours were also conducted. Although macaques are quite sensitive to amplitude increments, reversal of the relatively flat amplitude contours of these calls did not affect discrimination responses.
