PLATE A–PLATE B: USE OF SEQUENTIAL PRESENTATION IN THE TREATMENT OF FOOD SELECTIVITY

This study examined the effects of sequential presentation of foods on increasing acceptance of novel foods in a 16‐year‐old boy with autism spectrum disorder residing in a short‐term behavioral stabilization unit. The participant ate only 10 foods and one beverage prior to treatment. The intervention involved presenting a plate containing pea‐sized bites of novel foods (Plate A) and a plate containing spoonful‐sized bites of highly preferred foods (Plate B). After the participant consumed a bite from Plate A, he chose a bite from Plate B and was given a preferred beverage. The intervention, involving sequential presentation and establishing operations without the use of escape extinction, was successful in increasing the number of foods eaten from 10 to 24 while not increasing his maladaptive behaviors.

The Doctor-Patient Relationship in the Post-Managed Care Era

The growth of managed care was accompanied by concern about the impact that changes in health care organization would have on the doctor-patient relationship (DPR). We now are in a “post-managed care era,” where some of these changes in health care delivery have come to pass while others have not. A re-examination of the DPR in this setting suggests some surprising results. Rather than posing a new and unprecedented threat, managed care was simply the most recent of numerous strains on the DPR that have occurred throughout the century. These strains are a constant, inevitable consequence of the varying needs and concerns of patient and physicians as they seek to balance their desires for a certain type of DPR with their simultaneous desire for other aspects of care such as lower costs, greater technological sophistication, and improved outcomes.     

Insomniacs' perceived lack of control over sleep

Abstract

It is widely assumed that insomniacs have poor self-efficacy for sleep and it is known that successful treatment is usually accompanied by improved self-efficacy. However, there has been little detailed investigation of insomniacs perceived lack of control over sleep. Insomniacs' perceived control over sleep itself is affected more than their perceived control over pre-sleep mental activity or physical tension. It was hypothesised that insomniacs would diverge from controls more in their sense that sleep was out of their control than that sleep was under their control, though this was not supported by the data. Also, there was no clear support for the idea that insomniacs' dissatisfaction with their control over sleep was the product of excessive aspirations for control. One factor that seems likely to contribute to insomniacs' lack of perceived control over sleep is that they do not have as lawful a pattern of expectations of sleep, based on their recent pattern of sleep, as normal sleepers do. Insomniacs, like non-insomniacs, were most likely to attribute poor sleep to external stresses and an over-active mind. Insomniacs showed a wide range of heightened emotional reactions to poor sleep. The implications of the results for self-regulation approaches to the treatment of insomnia are discussed.     

Effects of processing speed on intelligence may be underestimated: Comment on Demetriou et al. (2013)

This commentary suggests ways to extend research by Demetriou et al. (2013), who may have underestimated the effects of processing speed on the development of intelligence. It argues that future research should consider variability in processing speed, complexity in speed tasks, and reaction times excluded from speed estimates.
