Testing a self-determination theory intervention for motivating tobacco cessation: supporting autonomy and competence in a clinical trial.

A longitudinal randomized trial tested the self-determination theory (SDT) intervention and process model of health behavior change for tobacco cessation (N = 1006). Adult smokers were recruited for a study of smokers' health and were assigned to intensive treatment or community care. Participants were relatively poor and undereducated. Intervention patients perceived greater autonomy support and reported greater autonomous and competence motivations than did control patients. They also reported greater medication use and significantly greater abstinence. Structural equation modeling analyses confirmed the SDT process model in which perceived autonomy support led to increases in autonomous and competence motivations, which in turn led to greater cessation. The causal role of autonomy support in the internalization of autonomous motivation, perceived competence, and smoking cessation was supported.     

Synchrony effects in automatic and controlled retrieval

Using a speeded retrieval procedure, we investigated time-of-day effects in automatic and controlled retrieval. Morning-type adults were tested at either peak (early morning) or off-peak (late afternoon) times on a speeded implicit (Experiment 1) or explicit (Experiment 2) stem completion task. In Experiment 1, retrieval strategies were identified by changes in response speed between a practice phase with rapid retrieval and an implicit memory test phase. Performance based on controlled retrieval (shown by slowdown participants) showed more priming at peak than at off-peak times of day, a finding confirmed in Experiment 2, in which the participants were given intentional retrieval instructions when the materials switched. In contrast, performance based on automatic retrieval (shown by nonslowdown participants) did not differ across peak and off-peak times. The finding suggests a robust synchrony effect in controlled retrieval, but not in automatic retrieval, which does not appear to vary across the day.     

The Political Ecology of Dignity: Human Dignity and the Inevitable Returns of Animality

Human dignity names a two‐tier political ecology: one moral‐political community whose members bear a special status of inviolability, and another larger community where violence and degradation are routine. Because ecological relations are never uni‐directional, the routinized violence that “belongs” in interactions with nonhuman animals returns, normalizing violence across gendered, racialized, and politicized lines of human difference. An account of dignity that begins from creaturely vulnerability rather than anthropological exceptionalism not only better expresses key theological insights of the Christian tradition, it also resists the repressed and disavowed violence generated by prevalent accounts of dignity.     

Anger and psychopathology in prison inmates

The relationship between anger and psychopathology was examined in a sample of 137 inmates. The State-Trait Anger Scale and the Anger Expression Inventory were used to measure anger and the Basic Personality Inventory was used to measure psychopathology. State and trait anger correlated positively with 8 and 9, respectively, out of 12 scales of psychopathology. The factor scales for the State-Trait Anger Scale, anger/hostility, arousal and situational anger correlated positively with 8, 9 and 4, respectively, out of 12 measures of psychopathology. Anger-control had an inverse relationship with 8 out of 12 measures of psychopathology, anger-out was positively related to measures of interpersonal problems, alienation, impulse expression and deviation, and anger-in had positive correlations with 11 out of 12 indices of psychopathology. Alternative treatment approaches which are sensitive to individual differences in anger style were discussed.     

USE OF EXTINCTION AND REINFORCEMENT TO INCREASE FOOD CONSUMPTION AND REDUCE EXPULSION

Extinction and reinforcement contingencies were used to treat 2 children with feeding disorders. Positive reinforcement and avoidance extinction effectively increased food acceptance but also increased food expulsion. Reduced expulsion and increased swallowing were achieved by repeated presentation of expelled food, a second extinction component.     

The Effect of Rational-Emotive Parent Education on the Stress of Mothers of Young Children with Down Syndrome

Parents of children with disabilities are likely to experience more stress than parents of normal children. This study assessed the effectiveness of a Rational-Emotive Parent Education Program (REPE) in reducing parental stress. The REPE program focused only on core irrationalities to determine the efficacy of elegant disputation. Mothers of young children attending an early intervention centre for Down syndrome were randomly allocated to three groups, experimental, REPE, n = 21; a comparative-treatment control, Applied Behaviour Analysis, (ABA) n = 17; and a no-treatment control, n = 16. A pretest post-test design was used with there being eight seminars of both the REPE and ABA programs. On both the Profile of Mood States and the Parenting Stress Index (Parent Domain) totals the REPE group showed significant reductions in stress compared with both control groups. The results from some subscales and single items suggested that the early intervention centre program also reduced stress. The REPE program using elegant disputation reduced parental stress.     

Detectability as a function of spatial location: effects of selective attention

In a series of previous reports we have described differences in detectability of a target in a background of nontarget patterns as a function of its spatial location. These differences, referred to as a "detectability gradient," have been attributed to target detection accomplished by a serial processing mechanism--a scan. The mathematical model of such a mechanism, developed in the previous report, is equally applicable to a series of attentional shifts or to a perceptual, i.e., a preattentive, mechanism. The present experiments were designed to test the hypothesis that this scan is attentional in nature. The results provide additional evidence for the scanning hypothesis but do not support the view that this scan represents a series of attentional shifts.     

Central auditory processing : IV. Ear dominance—Spatial and temporal complexity

Ear dominance for dichotically presented tones was measured in 63 right-handed subjects when the frequency difference (Δf) was small compared to the center frequency (f_c) and again when it was large. Although two-thirds of the population exhibited a left-ear dominance in both conditions, a shift toward right-ear dominance occurred when the Δf was increased. An additional study, employing the alternating tone illusion described by Deutsch, revealed the same general effect, i.e., a shift toward right-ear dominance with increasing values of Δf/f_c. The results of these experiments, coupled with a review of previously published data of other dichotic experiments, indicate that as the ratio of Δf/f_c increases, the subjective complexity of the sound image increases, and there is a progressive emergence of a “right-ear advantage” (or ear dominance). A tentative explanation relates these results to the effects of anatomical asymmetries of primary and auditory association cortex and the efferent temporal lobe enhancement mechanism described by R. Efron, P. H. Crandall, B. Koss, P. L. Divenyi, and E. W. Yund (Brain and Language, 1983, 19, 254–263.     

Central auditory processing: I. Ear dominance—A perceptual or an attentional asymmetry?

The phenomenon of ear dominance for pitch described by Efron and Yund has been attributed by them to an asymmetry of sensory origin in the binaural integration of dichotic tone pairs. An explanation of this phenomenon in terms of an attentional bias is rejected on the basis of two experiments where the possibility of such bias was excluded. These and other experiments indicate that a simple explanation of this ear dominance in terms of a hemispheric specialization in the processing of tonal stimuli also must be rejected.     

Temporal ordering deficits following anterior temporal lobectomy

Subjects were required to report the pitch sequence of two 10-msec tones of different frequency presented monaurally while the stimulus onset asynchrony (SOA) between the two tones was varied. The value of the SOA at which the subjects achieved an 80% correct sequence report was determined by an adaptive procedure without feedback. This measure was compared in the right and left ears, on subjects with a right or left anterior temporal lobectomy and on a normal control group. The results reveal an elevated threshold for performing temporal order judgments in the ear contralateral to the surgical lesion.
