The problem of parental nonadherence in clinical behavior analysis: effective treatment is not enough

Applied behavior analysts have developed many effective interventions for common childhood problems and have repeatedly demonstrated that childhood behavior responds to properly managed contingencies. The success of these interventions is dependent upon their basic effectiveness, as demonstrated in the literature, their precise delivery by the clinician to the parent, and adherence to or consistent implementation of the intervention. Unfortunately, arranging the consistent implementation of effective parenting strategies is a significant challenge for behavior analysts who work in homes, schools, and outpatient or primary care clinics. Much has been done to address issues of adherence or implementation in the clinic, but relatively little has been done to increase our understanding of the contingencies that affect parental adherence beyond the supervised clinic environment. An analysis of the contingencies that strengthen or weaken adherence might suggest strategies to improve implementation outside the clinic setting. What follows is an analysis of the variables associated with adherence by parents to recommendations designed to solve common childhood problems.     

Values and beliefs of vegetarians and omnivores

Following the claim by some anthropologists and sociologists that 1 symbolic meaning of meat is a preference for hierarchical domination (C. J. Adams, 1990; N. Fiddes, 1989; D. D. Heisley, 1990; J. Twigg, 1983), the authors compared the values and beliefs of vegetarians and omnivores in 2 studies conducted in New Zealand. They compared the full range of vegetarians and omnivores on right-wing authoritarianism, social dominance orientation, human values, and consumption values. The participants tending toward omnivorism differed from those leaning toward veganism and vegetarianism in 2 principal ways: The omnivores (a) were more likely to endorse hierarchical domination and (b) placed less importance on emotional states. Accordingly, the acceptance or rejection of meat co-varied with the acceptance or rejection of the values associated with meat; that finding suggests that individuals consume meat and embrace its symbolism in ways consistent with their self-definitions.     

Neural representation of consciously imperceptible speech sound differences

The concept of subliminal perception has been a subject of interest and controversy for decades. Of interest in the present investigation was whether a neurophysiologic index of stimulus change could be elicited to speech sound contrasts that were consciously indiscriminable. The stimuli were chosen on the basis of each individual subject's discrimination threshold. The speech stimuli (which varied along an F3 onset frequency continuum from /da/ to /ga/) were synthesized so that the acoustical properties of the stimuli could be tightly controlled. Subthreshold and suprathreshold stimuli were chosen on the basis of behavioral ability demonstrated during psychophysical testing. A significant neural representation of stimulus change, reflected by the mismatch negativity response, was obtained in all but 1 subject in response to subthreshold stimuli. Grand average responses differed significantly from responses obtained in a control condition consisting of physiologic responses elicited by physically identical stimuli. Furthermore, responses to suprathreshold stimuli (close to threshold) did not differ significantly from subthreshold responses with respect to latency, amplitude, or area. These results suggest that neural representation of consciously imperceptible stimulus differences occurs and that this representation occurs at a preattentive level.     

Trust in managed care organizations

Two basic criticisms of managed care are that it erodes patient trust in physicians and subjects physicians to incentives and pressures that compromise the physician's fiduciary obligation to the patient. In this article, I first distinguish between status trust and merit trust, and then argue (1) that the value of status trust in physicians is probably over-rated and certainly underdocumented; (2) that erosion of status trust may not be detrimental if accompanied by an increase in well-founded merit trust; and (3) that under conditions of managed care the physician's commitment to traditional medical ethics cannot serve as an adequate basis for merit trust. Next, drawing on an analogy between managed care organzations and politics, I argue that (4) the most appropriate basis for merit trust in managed care is a conception of organizational legitimacy that includes procedural justice, empowerment of constructive criticism within the organization, and organizational accommodation of the noninstrumental commitment to patient well-being that is distinctive of medical professionalism. I then explore the conditions necessary for robust competition for merit trust among managed care organizations and indicate the kinds of public policies needed to facilitate such competition. Finally, I show how the account of organization-based merit trust can accommodate the special fiduciary obligation of medical professionals, without indulging in the delusion that it is the physician's fiduciary obligation always to provide all care that is expected to be of any net benefit to the patient.     

Pigeon reaction time, Hick’s law, and intelligence

Pigeons' choice reaction times (RTs) increased as a linear function of log2 number of potential target stimuli (Experiments 1-3), as would be predicted by Hick's law. The values of intercepts and slopes decreased with training (Experiments 2 and 3) and with differential reinforcement of short RTs under percentile reinforcement contingencies (Experiment 3). RT functions obtained from human subjects were also consistent with Hick's law, but slopes for pigeons were significantly lower than those for humans (Experiments 4 and 5). These results extend the generality of Hick's law to pigeons but are inconsistent with Jensen's claim that the parameters of the Hick function are related to intelligence.
