Assessment and treatment of response to name for children with autism spectrum disorder: Toward an efficient intervention model

Response to name (RTN) is an early developmental milestone, deficits in which are associated with autism spectrum disorder (ASD). This study extends previous research by evaluating an assessment and treatment model for RTN with 13 children with ASD. For all participants, phase 1 was a naturalistic social baseline. The 9 children who did not meet mastery criteria in phase 1 underwent a series of treatment conditions in phase 2. In phase 3, treatment components were removed, and generalization was assessed. Results indicated that tangible reinforcement procedures can produce rapid increases in discriminated RTN, sometimes without prompts. The total number of trials to mastery were reduced in the current study relative to previous research. Results also provide preliminary evidence to suggest that the phase 1 baseline condition may produce distinct patterns of RTN that could be used to predict treatment effects and further reduce trials to mastery in future work.

Social discounting of pain

Impatience can be formalized as a delay discount rate, describing how the subjective value of reward decreases as it is delayed. By analogy, selfishness can be formalized as a social discount rate, representing how the subjective value of rewarding another person decreases with increasing social distance. Delay and social discount rates for reward are correlated across individuals. However no previous work has examined whether this relationship also holds for aversive outcomes. Neither has previous work described a functional form for social discounting of pain in humans. This is a pertinent question, since preferences over aversive outcomes formally diverge from those for reward. We addressed this issue in an experiment in which healthy adult participants (N = 67) chose the timing and intensity of hypothetical pain for themselves and others. In keeping with previous studies, participants showed a strong preference for immediate over delayed pain. Participants showed greater concern for pain in close others than for their own pain, though this hyperaltruism was steeply discounted with increasing social distance. Impatience for pain and social discounting of pain were weakly correlated across individuals. Our results extend a link between impatience and selfishness to the aversive domain.     

The effects of methylphenidate on levels of processing and laterality in children with attention deficit disorder

Effects of stimulant medication (methylphenidate) on levels (feature, name, semantic) of word processing by the left and right hemisphere were assessed in 31 attention- deficit- disordered children. In a double-blind procedure, same- different decisions were made to tachistoscopically presented word pairs under medication and placebo. Analysis of manual response times failed to show any negative effects of medication. Feature decisions were faster than name decisions, which were faster than semantic decisions. Methylphenidate induced a right visual field advantage (left hemisphere) for the name decision, which was interpreted as a normalization effect. The results suggest that (1) methylphenidate may selectively improve the phonological level of word processing and (2) methylphenidate's favorable therapeutic effect is produced through inhibition of excessive right hemisphere activity in response to task demands that engage the left hemisphere.This research is based in part upon a doctoral thesis completed by the first author in the Department of Education, University of Toronto.

Drawing on the experiences of alternative decision-makers: Can we preserve the jury in complex civil litigation?

Many have questioned the wisdom of using traditional juries to decide cases involving complex scientific and technical evidence. Alternative decision-makers that have been proposed include: judges; expert arbitrators; special juries composed of people who possess either a minimum level of higher education or knowledge especially relevant to the issues in the particular trial; and panels of experts in the particular field, acting as either a jury or a non-jury tribunal. These alternatives differ from the traditional jury not only in their composition but also, to varying degrees, in terms of the resources available to them and the procedures under which they operate. In this article, we explore the advantages that these alternative decision-makers have over juries and discuss how the same resources and procedures enjoyed by the alternatives could be made available to and enhance the abilities of the traditional jury in cases involving complex evidence.     

Memory phenomena in the law

Memory issues arise in the law in many different ways. At the most fundamental level, assumptions about memory are inherent in both substantive laws and procedural rules that govern the operation of the legal system. For example, the rules and procedures used to govern the conduct of jury trials reflect a great deal of faith in jurors' ability to understand and retain information over long periods of time, often with much intervening information. Memory issues also arise in the context of individual cases. For example, the ability of an attorney to satisfactorily prosecute or defend a case on behalf of a client often relies largely upon the completeness and accuracy of the memory of the client and other witnesses. This paper discusses examples of memory issues in the law and describes how applied research on these issues can be used to inform basic memory theory, particularly with respect to the relationship between emotion and memory.     

Exploring the utility of functional analysis methodology to assess and treat problematic verbal behavior in persons with acquired brain injury

Functional analyses were conducted on four adults with acquired brain injuries who regularly displayed instances of inappropriate verbal behavior including depressive, aggressive, suicidal, profane, and sexually inappropriate utterances. After the functional analysis yielded a maintaining variable for each participant, a function‐based intervention consisting of differential reinforcement of alternative verbal behavior was implemented. Results of the behavioral interventions show that instances of vocal behavior can be assessed and subsequently treated using the functional analysis methodology often reserved for nonverbal forms of behavior. The utility of functional analysis for assessing complex human behavior is discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

An Empirical Test of Target Congruence Theory on Intimate Partner Violence

The purpose of the current study was to test target congruence theory as an explanation of intimate partner violence. Specifically, the effects of target vulnerability, target gratifiability, and target antagonism were examined for their effects on intimate partner violence against women. To do this, data collected in 2009 from a sample of 1,452 respondents to the Canadian General Social Survey were analyzed using binary logistic regression. Overall, the results suggest support for the theory, particularly for the concept of target gratifiability, and for target vulnerability to a lesser degree. As the first study to apply the theory to intimate partner violence, findings suggest that target congruence may be a valuable theoretical perspective in understanding victimization risk.     

Situation selection across adulthood: the role of arousal

In this study, we investigated age differences in situation selection to understand the role stimulus arousal plays in motivating age differences in this type of emotion regulation. Participants freely selected from a set of affective videos using information about the valence and arousal of each stimulus. There were age differences both in the valence and arousal of selected stimuli. Older adults selected more neutral and low-arousal stimuli while younger adults selected more negative and high-arousal stimuli. We consider these results in light of recent theoretical models and conclude that studies of age differences in emotion regulation must consider both valence and arousal.
