Assessing the social validity of telehealth-based applied behavior analysis services for autism spectrum disorder

During the COVID-19 pandemic, applied behavior analysis services for many autistic individuals were transitioned to telehealth. The current study assessed caregiver-reported quality of life (QoL) and social validity for families of autistic children receiving only telehealth services (n = 96) or a combination of telehealth and in-person services (n = 173). Barriers to the telehealth experience were analyzed via an ANOVA, and the impact of funding source was analyzed using an independent samples t-test. Caregivers reported benefit across QoL and social validity items, with scores ranging from 3.31 to 4.44 (1 = least benefit, 5 = most benefit). While many caregivers reported no barriers regarding technology (44.61%), childcare (69.52%), and employment (64.68%), the presence of those barriers significantly impacted QoL and social validity scores. Funding source was not found to have a significant impact. Overall, caregivers found value in their child's telehealth services. Clinicians have an obligation to mitigate barriers to ensure the success of the intervention.     

Teaching self-control to small groups of dually diagnosed adults

The present study examined the use of a progressive delay procedure to teach self-control to two groups of dually diagnosed adults. When given a choice between an immediate smaller reinforcer and a larger delayed reinforcer, both groups chose the smaller reinforcer during baseline. During treatment, progressive increases in work requirements for gaining access to a larger reinforcer resulted in both groups selecting larger delayed reinforcers. The results are discussed with respect to increasing cooperative work behavior and self-control.     

Tactile gap detection and language lateralization

Recent work suggests that hemispheric language lateralization might be related to the fine-grained temporal discriminations that are required for linguistic processing (Nicholls, 1996). Studies concerning tactile processing have also shown a significant left-hemisphere (L-H) advantage for tactile gap detection (Nicholls & Whelan, 1997). We hypothesized that language and tactile processing are both preferentially processed by the left hemisphere because it is specialized for tasks requiring fine-grained temporal resolution. Thirty-two participants (16 right and 16 left handers) were tested for both linguistic processing (using the Fused Dichotic Words Test (FDWT)) and tactile gap detection. Both right and left handers showed a significant L-H advantage for both language processing and tactile gap detection. The present study supports recent claims that language lateralization is attributable to the left hemisphere's better suitability to process tasks that require fine-grained temporal resolution.     

Contrived motivating operations alter delay‐discounting values of disordered gamblers

The present study required 9 disordered gamblers to make hypothetical selections between smaller and larger amounts of money at varying delays. Participants were also required to respond to the task given the contrived hypothetical conditions of earning twice or half as much as they did at their current jobs. The results demonstrated how participants’ delay discounting was altered via contrived motivating operations, strengthening the argument that discounting may be a state variable.

Complex Concepts

For some time cognitive anthropology, and indeed cognitive science generally, have been concerned with issues of conceptual representation. Inadequacies in classical and more recent approaches, in particular, prototype theories, have motivated a search for alternative accounts. We propose an approach to conceptual representation that requires the specification of domain theories, from which conceptual definitions are generated, and within which the relations among concepts can be formalized. We demonstrate the utility of a formal characterization of this view of domains and concepts in the analysis of an aspect of the basic metaphysics constructed by the people of West Futuna, Vanuatu. In the process, we expand the set of formal devices traditionally relied upon by anthropologists and others involved in cognitive studies, and thereby gain insight into the complexity of the metaphysical beliefs of an Oceanic people.
