A controlled evaluation of the impact of a parent training programme on child behaviour and mothers' general well-being

This study was designed to assess the impact of a parent training programme run by the Eastern Health Board (EHB) on two factors, child behaviour and mothers' general well-being. Thirty-nine mothers (Experimental group), and forty mothers on a waiting list for the course (Control group), were assessed before the Experimental group commenced the course and again when the Experimental group had completed the course. The Experimental group was also assessed one year after completing the course. Although initially the Control group started from a slightly better position, statistically significant for one of the four measures, mothers in the Experimental group changed more during the course and rated their children as having fewer and less intense behavioural problems, and saw themselves as having fewer psychological symptoms and increased levels of self-esteem at post-course assessment. These beneficial effects were maintained at follow-up.     

Characteristics that help mothers maintain their infants'' focus of attention

Disadvantaged mothers' use of interactive strategies which maintained their infants' focus of attention were examined at 6, 12, and 24 months to evaluate for patterns in this interactive strategy and determine if patterns could be predicted from early infant and maternal characteristics. Four distinct clusters were identified with mothers in each cluster increasing in their use of maintaining over time but differing in the age at which the increase occurred. While infants' biologic risk was unrelated to cluster membership, more positive scores on mothers' perceptions of child rearing history, child rearing attitudes, self-esteem, and social support when the infants were 6 months old were reported by mothers who displayed a pattern of high levels and steady increase in maintaining. More negative scores on these characteristics were reported by mothers who displayed low levels of maintaining and delays in increasing this interactive strategy. Results are discussed in light of disadvantaged mothers' ability to adapt to their infants' changing needs and early identification of mothers' who may have greater difficulty in the adaptational process.     

The Relations of Regulation and Emotionality to Children's Situational Empathy-Related Responding

The relations of dispositional regulation (attentional control, ego control), ego resiliency, and emotionality (general emotional intensity and negative emotionality) to situational measures of sympathy and personal distress were examined. Situational sympathy and personal distress were assessed with facial, self-reported, and heart rate reactions to an empathy-inducing film. Teachers and parents completed measures of children's dispositional regulation and emotionality. In general, children who evidenced sympathy (e.g., facial sadness, mean heart rate decline, and self-reported sympathy) were rated higher in regulation and resiliency, although findings sometimes were obtained for only one sex. Children who evidenced personal distress (e.g., facial distress), as well as facial sadness, were rated relatively high in emotionality. Gaze aversion from the film was correlated with regulation and boys' resiliency, and was negatively related to negative emotionality.     

The Continuum of Deep/Surface Dyslexia

A right-handed male sustained traumatic brain injury which resulted in anomia, dyslexia, and agraphia. The most severe CT (computed tomography)-identified brain damage was located in the right parieto-temporal lobe. In the first months following the injury, the pattern of reading errors was similar to that associated with deep dyslexia. However, nonlexical derivation of phonology from print was not abolished. As the patient's ability to associate letter patterns with sounds improved, oral reading also improved. Although he no longer produced semantic errors in oral reading, he continued to produce oral reading errors that were visually and phonologically related to the targets. Four months after the injury, the error pattern observed in the patient's oral reading was consistent with very mild surface dyslexia. The significance of these observations to dual-deficit models of acquired dyslexia is discussed, as are their implications for rehabilitation.     

A Postmodern Analysis of a Course on Clinical Supervision

A qualitative study of a supervision course included pre-and post-interviews of the participants in addition to in-class participant observation. In an effort to be consistent with a postmodern perspective, the data were reviewed by the four members of the research team, each of whom shares his or her analysis, or story. Common themes which emerged in response to the focus on student change include greater awareness of isomorphic processes, ethical and legal issues, and evaluative processes.     

Neural Systems Mediating American Sign Language: Effects of Sensory Experience and Age of Acquisition

ERPs were recorded from deaf and hearing native signers and from hearing subjects who acquired ASL late or not at all as they viewed ASL signs that formed sentences. The results were compared across these groups and with those from hearing subjects reading English sentences. The results suggest that there are constraints on the organization of the neural systems that mediate formal languages and that these are independent of the modality through which language is acquired. These include different specializations of anterior and posterior cortical regions in aspects of grammatical and semantic processing and a bias for the left hemisphere to mediate aspects of mnemonic functions in language. Additionally, the results suggest that the nature and timing of sensory and language experience significantly impact the development of the language systems of the brain. Effects of the early acquisition of ASL include an increased role for the right hemisphere and for parietal cortex and this occurs in both hearing and deaf native signers. An increased role of posterior temporal and occipital areas occurs in deaf native signers only and thus may be attributable to auditory deprivation.     

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.
