Major legal and ethical issues in behavioral treatment: Focus on institutionalized mental patients

Proponents of behavior therapies advocate expanded use of this approach based on its pragmatics and clinical successes. Critics, however, point not only to abuses in implementation, but charge that the behavioral approach is inherently unethical, especially when used with institutionalized mental patients. This article will review these arguments as well as provide an updated exploration of relevant court decisions impacting behavioral treatment in mental institutions. Suggested courses of action are then provided.     

Paranormal beliefs: their dimensionality and correlates

Lack of conceptual clarity and multivariate empirical studies has troubled research on superstitious, magical and paranormal beliefs. We defined paranormal beliefs as beliefs in physical, biological or psychological phenomena that feature core ontological properties of another ontological category. The aim was to bring together a range of beliefs and their potential correlates, to analyse whether the beliefs form independent subsets, and to test a structural model of the beliefs and their potential correlates. The results (N = 3261) showed that the beliefs could be best described by one higher‐order factor. There were also four lower‐order factors of paranormal beliefs but their explanatory power was low. Magico‐religious beliefs were best explained by high intuitive thinking, a humanistic world view and low analytical thinking. Copyright © 2006 John Wiley & Sons, Ltd.     

Effects of perceptual and conceptual similarity in lexical priming of young children who stutter: preliminary findings

The purpose of this study was to investigate the influence of conceptual and perceptual properties of words on the speed and accuracy of lexical retrieval of children who do (CWS) and do not stutter (CWNS) during a picture-naming task. Participants consisted of 13 3–5-year-old CWS and the same number of CWNS. All participants had speech, language, and hearing development within normal limits, with the exception of stuttering for CWS. Both talker groups participated in a picture-naming task where they named, one at a time, computer-presented, black-on-white drawings of common age-appropriate objects. These pictures were named during four auditory priming conditions: (a) a neutral prime consisting of a tone, (b) a word prime physically related to the target word, (c) a word prime functionally related to the target word, and (d) a word prime categorically related to the target word. Speech reaction time (SRT) was measured from the offset of presentation of the picture target to the onset of participant's verbal speech response. Results indicated that CWS were slower than CWNS across priming conditions (i.e., neutral, physical, function, category) and that the speed of lexical retrieval of CWS was more influenced by functional than perceptual aspects of target pictures named. Findings were taken to suggest that CWS tend to organize lexical information functionally more so than physically and that this tendency may relate to difficulties establishing normally fluent speech and language.

Educational objectives: The reader will learn about and be able to (1) communicate the relevance of examining lexical retrieval in relation to childhood stuttering and (2) describe the method of measuring speech reaction times of accurate and fluent responses during a picture-naming task as a means of assessing lexical retrieval skills.
