Behavioral contrast and generalization across settings in the treatment of autistic children

Previous research on the generalization of treatment gains across settings has typically focused on the question of whether generalization occurs or does not occur. However, the experimental literature suggests another possibility: that behavioral contrast may occur in extra-therapy settings if the reinforcement procedures in the therapy setting are highly discriminable from those in other settings. Therefore, this investigation was designed to systematically assess whether: (1) a highly discriminable treatment procedure in one setting would produce a behavioral contrast effect in other unmanipulated settings; and (2) such contrast-like trends could be eliminated if initially different reinforcement procedures in two settings were subsequently made similar. The results for the eight autistic children who participated in this investigation showed that: (1) When very different reinforcement procedures (primary rewards or punishment in therapy settings, and no rewards or punishment in extra-therapy settings) were in effect, the children showed contrast-like behavior changes in the untreated extra-therapy settings; and (2) such trends in responding could be eliminated, resulting in generalization of treatment gains, if the reinforcement procedures were subsequently made relatively similar in the two settings, even if the procedures consisted essentially of noncontingent reinforcement.     

The influence of task variation and maintenance tasks on the learning and affect of autistic children

Analyses of autistic children's learning and affect have begun to consider the role of antecedent variables, including the manner with which tasks are sequenced within instructional sessions. Within the context of a simultaneous-treatments design, this experiment evaluated autistic children's affect and rate of task acquisition under three experimental conditions. The conditions were (1) a constant task condition in which only one acquisition task was presented per session; (2) a varied-acquisition-task condition, in which 10 acquisition tasks were randomly interspersed throughout each session; and (3) a varied-with-maintenance-task condition, which randomly interspersed 5 acquisition tasks and 5 which had been previously acquired. The results showed significantly more efficient learning under the varied-maintenance condition, with no consistent differences separating the other two conditions. In addition, observers' ratings of the children's affect showed that the most positive judgments were produced by the varied-maintenance condition. The varied-acquisition condition was next while the constant task condition always produced the least favorable ratings. These findings are discussed in relation to the literature on massed versus distributed practice, stimulus variation, and success-induced motivation. The implications for upgrading the treatment and education of handicapped children are also reviewed.     

Teaching autistic children to respond to simultaneous multiple cues

A number of studies have shown that autistic children tend to learn new discriminations by responding to only a restricted number of available cues and that this may be responsible for some of their abnormal behavior. Therefore, this investigation assessed the feasibility of teaching autistic children to respond to multiple cues. The results showed that four autistic children could learn a conditional discrimination requiring them to discriminate a multiple-cue complex from each of its two component cues. However, the autistic children did not learn this discrimination in the same manner as normal children. In the early trials, the autistics responded at a higher level to one of the two component cues. Only after many trials did the autistics respond equally on the basis of both component cues. The results of an initial attempt to teach a general set to respond to multiple cues showed that, when an autistic child was taught a series of successive conditional discriminations, the child eventually learned a set to approach new discriminations by responding equally on the basis of both component cues. The results are discussed in terms of understanding and treating autistic children's abnormal development.     

Coach identity leadership behaviours are positively associated with athlete resource appraisals: The mediating roles of relational and group identification

BackgroundThere is growing evidence identifying the positive effects of sport and exercise leaders engaging in identity leadership. Yet we have limited knowledge of how identity leadership is associated with athletes’ resource appraisals (e.g., self-efficacy) and performance, the underpinning mechanisms that explain such relationships, and changes in relationships across a sporting season.MethodsIn Study 1, 412 amateur and professional athletes completed seven questionnaires directly prior to athletic competition in a cross-sectional design. In Study 2, 136 athletes completed seven questionnaires directly before competition, and one questionnaire directly after competition both at the start and the end of the athletic season.ResultsIn Study 1, relational identification and group identification mediated the positive relationship between identity leadership and self-efficacy, control, approach goals and social support. In Study 2, identity leadership at the start of the season predicted self-efficacy at the end of the season through relational identification. Group identification did not significantly mediate the identity leadership-resource appraisal relationship. Perceived social support at the start of the season predicted greater performance satisfaction at the end of the competitive season.ConclusionsFindings provide evidence that sport coaches’ engagement in identity leadership is key to forming a shared social identity, which in turn, is broadly adaptive for stress appraisals and performance satisfaction both cross sectionally and longitudinally.     

Meeting the challenges in the delivery of child and adolescent mental health services in the next millennium: The continuous quality improvement approach

Managed care and concerns about the effectiveness of services are major pressures on mental health services. An approach to dealing with the challenges of providing high-quality, cost-effective services is continuous quality improvement or CQI. This article describes four major themes that motivate the CQI approach. However, we also describe the major obstacles in using an approach originally designed for manufacturing for human services. The need to accurately measure both treatment processes and outcomes is emphasized.     

Habituation of the orienting reflex and the development of Preliminary Process Theory

The orienting reflex (OR), elicited by an innocuous stimulus, can be regarded as a model of the organism’s interaction with its environment, and has been described as the unit of attentional processing. A major determinant of the OR is the novelty of the eliciting stimulus, generally operationalised in terms of its reduction with stimulus repetition, the effects of which are commonly described in habituation terms. This paper provides an overview of a research programme, spanning more than 30 years, investigating psychophysiological aspects of the OR in humans. The major complication in this research is that the numerous physiological measures used as dependent variables in the OR context fail to jointly covary with stimulus parameters. This has led to the development of the Preliminary Process Theory (PPT) of the OR to accommodate the complexity of the observed stimulus–response patterns. PPT is largely grounded in autonomic measures, and current work is attempting to integrate electroencephalographic measures, particularly components in the event-related brain potentials reflecting aspects of stimulus processing. The emphasis in the current presentation is on the use of the defining criteria of the habituation phenomenon, and Groves and Thompson’s Dual-process Theory, in the development of PPT.     

A strange hand: On self-recognition and recognition of another

This article provides a phenomenological analysis of the difference between self-recognition and recognition of another, while referring to some contemporary neuroscientific studies on the rubber hand illusion. It examines the difference between these two forms of recognition on the basis of Husserl’s and Merleau-Ponty’s work. It argues that both phenomenologies, despite their different views on inter-subjectivity, allow for the specificity of recognition of another. In explaining self-recognition, however, Husserl’s account seems less convincing. Research concerning the rubber hand illusion has confirmed that self-recognition involves more than an immediate experience of oneself. Merleau-Ponty’s later work, describing self-recognition as the result of assimilative identification, will be used to explain the possibility of illusion between one’s “hereness” and “thereness”. The possibility of this illusion is inherent to self-recognition, while it is lacking in recognition of another.

The Mother-child Relationship as an Archetype for the Relationship between the Virgin Mary and Humanity in the Gospels and the Book of Revelation

Following the work of Stevens Rogers (2002), this article starts with the premise that humanity can be seen as a child growing in changing relationship with his or her mother. With Jesus representing humanity, the relationship between a mother and a child can be an archetype for understanding the changing relationship between the Virgin Mary and humanity as narrated in the Gospels and the Book of Revelation. With the Annunciation by the Angel, the Boy Jesus in the Temple, the wedding at Cana, and Mary at the foot of the cross as developmental stages, this article shows the changing relationship between humanity and the Virgin Mary.

Influence du contexte sémantique sur la performance d'identification d'odeurs

Our olfactory knowledge is mainly implicit and the last step for cognitive processing of odors — naming — is not always performed. To facilitate naming, odor identification by forced choice between alternatives is used. However, presenting names induces semantic priming. To assess which level of spontaneous odor processing is influenced by semantic context, we compared three priming conditions. Our results indicate that the identification process is based mainly on the rejection of semantic categories that are most remote from the target, and firstly of those with a different hedonic valence. The analysis of identification errors supports the hypothesis that odor naming rests more on global semantic discriminations than on what is called lexical access in other sensory modes.
