Using a Behavioral Treatment Package for Sleep Problems in Children With Autism Spectrum Disorders

This study investigated the effectiveness of a behavioral treatment package for sleep problems in children diagnosed with Autism Spectrum Disorders. Treatment consisted of four behaviorally based components: circadian rhythm management, positive bedtime routines, white noise, and graduated extinction. A multiple-baseline design across three participants was used. Families completed a baseline of various lengths followed by 1 month of intervention. Results indicated the treatment package was effective in decreasing sleep onset latency and the frequency of night awakenings. A week of follow-up data showed continued improvement. Parents reported their children slept better and satisfaction with the four intervention components.     

Changes in Sensation Seeking and Need for Structure Before and After a Combat Deployment

In this study, soldiers' adaptation with the situational demands on combat deployment is explored. Certain changes on the level of two needs-based personality characteristics, Sensation Seeking (SS) and Need for Structure (NS) take place across deployment: soldiers who are lower in SS were more inclined to seek for sensations after deployment, and soldiers at the extremes of the NS dimension, modified their behavioral tendencies after deployment towards a moderate level. According to our findings, these changes suggest at least temporal characteristic adaptations with certain environmental demands. We discuss the implications of these findings for research and practice.     

Stem Tones Pre-activate Suffixes in the Brain

Results from the present event-related potentials (ERP) study show that tones on Swedish word stems can rapidly pre-activate upcoming suffixes, even when the word stem does not carry any lexical meaning. Results also show that listeners are able to rapidly restore suffixes which are replaced with a cough. Accuracy in restoring suffixes correlated positively with the amplitude of an anterior negative ERP elicited by stem tones. This effect is proposed to reflect suffix pre-activation. Suffixes that were cued by an incorrect tone elicited a left-anterior negativity and a P600, suggesting that the correct processing of the suffix is crucially tied to the activation of the preceding validly associated tone.     

Amelioration of infant sleep disturbances: II. Effects of scheduled awakenings by compliant parents

Twelve infants and toddlers who exhibited spontaneous awakening and crying episodes during the night were subjected to scheduled awakenings by their parents. Scheduled awakenings were determined from individual baseline data, and these consisted of awakening, feeding, and consoling the child about 15 to 30 minutes before typical spontaneous awakening times. Once spontaneous awakenings were precluded, scheduled awakenings by the parents were faded out and posttreatment data were collected. The technique appeared effective for most children when the parents complied with the procedure.     

The Portrayal of Aggression on North American Television1

The past decade has seen an accumulation of evidence that TV viewing influences beliefs about social reality, particularly in areas related to violence. Detailed content analyses of the portrayal of aggression on North American television were conducted in an attempt to document some of the symbolic messages in television content and the extent to which those messages vary according to program category. The TV sample analyzed consisted of 109 programs (81 hours) chosen on the basis of audience viewing figures; 76% were produced in the U.S.A. and 22% in Canada. An average of 9 acts of physical aggression and 7.8 acts of verbal aggression per program hour were observed, but both type and rate of aggression varied by program category. Other methods of conflict resolution occurred rarely, and few witnesses sought alternatives to aggression. Less than 2% of the aggression observed was accidental, and most (69%) was incidental to the plot. Aggression, especially verbal abuse, was often portrayed as humorous, and there was little evidence of consequences. Some differences between Canadian and U.S. programming were noted. The possibility of using schema theory to understand the role of television in the development of beliefs about social reality is explored.     

A Practical Account of Autonomy: Why Genetic Counseling is Especially Well Suited to the Facilitation of Informed Autonomous Decision Making

In genetic counseling, facilitation of autonomous decision-making is seen as a primary aim and respect for autonomy is used to justify a nondirective counseling approach whereby clients are free to make their own choices after being given all necessary information. However in the genetic counseling literature, autonomy as a concept appears to be interpreted variably and often narrowly. We offer a practical account of autonomy that is coherent, consistent and philosophically defensible for the genetic counseling setting. At the same time we demonstrate how nondirective counseling may serve to frustrate rather than facilitate client autonomy. We suggest that promoting purposeful dialogue rather than counseling that is nondirective is more conducive to client autonomy.     

A new technique for measuring thermoregulatory behavior in the rat

A tracking procedure was used to investigate the ability of rats to regulate their ambient temperature. Rats were placed in a chamber with two levers; depressions of one lever controlled a cold-water flow (11 degrees C) and the other controlled the flow of hot water (57 +/- 1 degrees C). If it alternated responses, the rat could regulate temperature within these two extremes. With training, this regulatory behavior resulted in a narrow environmental temperature range that approximated normal body temperature.     

Uncertainty and values: The case of environmental impact assessment

The increasing complexity of policy issues, as well as the centering of environmental issues in the policy arena, has led to an increased dependence on science in public policy. This has, in turn, led to increased attention to, among other things, the science-policy relationship and the way in which scientific uncertainty is treated in the public sphere. This article examines both problems in the field of environmental impact assessment (EIA). Our study reveals that, apart from the epistemic uncertainty concerned with the predictive capability of scientific theories, EIA brings additional components of uncertainty and challenges for the policymaker. We further confirm recent findings with respect to the inadequacy of the traditional rational model to account for extant science-policy relationships. The article also posits an alternative model that allows one to unpack the processual components of the science-policy relationship.
