Excuses: their effective role in the negotiation of reality 总被引:4,自引:0,他引:4

A single-subject design often used to compare the effectiveness of two or more independent variables (like treatment programs) is the multielement (alternating treatments or simultaneous treatments) design. Variants of this design approximate the concurrent comparison of the effects of two or more variables (or levels of variables) by programming the variables (or levels) in rapid alternation, typically across or within daily sessions. Properly combined with conventional reversal designs, these designs can also display a variety of interaction effects, some of them worrisome, others highly desirable for the future development of the field. A worrisome model is the possibility that when Treatment B alternates rapidly with Treatment C, the effects of each will not be the same as when each is the only treatment used. A desirable model is the use of the multielement design as a fast-paced component of an otherwise conventional reversal design examining contextual control of some relationship: the possibility that some behavior responds differently to Controlling Variables A and B in Context X than in Context Y. This second possibility opens single-subject designs to the more efficient examination of all interactive effects and is highly desirable, considering the prevalence and importance of interactions in determining the limits and the generality of currently understood behavioral phenomena. 相似文献

The present study assessed a 24-hr time course for the acute effects of intramuscular injections of atropine sulfate (0, 1.5, 3.0, and 6.0 mg/70 kg) in healthy adult humans responding under a two-component multiple schedule of repeated acquisition and performance of response sequences. Subjects resided in an inpatient research ward for the duration of the study. In each component of the multiple schedule, subjects completed a different sequence of 10 responses in a predetermined order using three keys of a numeric keypad. In the acquisition component, the subjects' task was to acquire a new sequence each session. Eight sessions were conducted daily: one immediately before administration of the drug and then 0.5, 1.5, 3.0, 5.0, 7.0, 9.0, and 24.0 hr after administration. In the performance component, the response sequence always remained the same. Overall percentage of errors increased and overall response rates decreased in the acquisition and performance components as an orderly function of drug dose. However, these effects were selective in that behavior in the acquisition component generally was affected at lower doses than in the performance component. When behavior was affected in both the acquisition and performance components, the time courses of effects were similar. Drug effects began at 0.5 or 1.5 hr, reached peak effects between 3.0 and 5.0 hr, and returned to placebo levels between 7.0 and 9.0 hr postdrug in both schedule components. None of the drug doses produced reliable effects the day after drug administration (24-hr postdrug) in either schedule component. The present study provides the first within-subject assessment of the magnitude and duration of the effects of an anticholinergic on repeated acquisition and performance baselines and extends to atropine the selective effects on these two baselines demonstrated previously with other compounds in humans and nonhumans. 相似文献

This study investigated the subordinate liking and the leadership style of male and female managers in a simulated business activity. Sixty-seven female and 290 male undergraduate and graduate business students participated in this study. Female managers, on average, were not less well liked, nor were they more accommodative than male managers. Among managers classified as distinctly accommodative, females were not better liked than males; among managers classified as distinctly directive, females were significantly better liked than males. Under pressure to act in a directive manner, males tended to make use of their secondary leadership style as defined by F. E. Fiedler (1972), while females did not. 相似文献

The contributions of J. R. Kantor and his system of interbehavioral psychology to the field of behavior analysis are examined. Two sources of information served to organize this investigation: (1) the historical record as described in the literature and (2) the results of a questionnaire survey sent to past and present editorial board members of the Journal for the Experimental Analysis of Behavior, the Journal of Applied Behavior Analysis, and Behaviorism. The outcome of this investigation showed that Kantor has had a broader influence than might heretofore have been recognized. More importantly, contemporary behavior analytic research and theory are evolving in directions either influenced by, or consonant with, his approach. We conclude that Kantor's interbehavioral psychology and his writings offer an important and valuable source of ideas and concepts for the future of behavior analysis. 相似文献

Explored the distribution and temporal patterning of daily pain reported by 47 patients with rheumatoid arthritis (RA) for 75 consecutive days. Approximately half the pain series were significantly positively skewed, trended significantly across the recording period, or both. One fourth of the sample had relatively painful "outlier" days that clustered together. Most series displayed a significant autocorrelation in pain intensity across successive days even when the series were detrended. Patients with more active disease had pain that was more intense but more predictable from day to day and reported fewer painful outlying days and briefer episodes of atypically severe pain. Patients describing themselves as more depressed on the Center for Epidemiological Stress Depression Scale also reported more intense pain across the recording period, independent of their level of disease activity and disability. Implications for daily process studies of RA pain are discussed. 相似文献

In the last three decades, some Thomists have argued that receiving is a pure perfection, others that it is a transcendental, and others that it is neither. All agree, however, that Aquinas himself holds that it is neither a pure perfection nor a transcendental. I argue here that, while Aquinas does not number receiving among the pure perfections or the transcendentals, he comes closer to doing so than has been acknowledged, and – at least in one respect – he even associates reception more radically with perfection than do any of the more recent champions of receptivity. 相似文献

Variety-seeking research has examined antecedents in terms of contextual factors and individual differences. However, it does not consider the interaction of individual difference factors such as regulatory focus (promotion vs. prevention) and regulatory mode (locomotion vs. assessment) to predict variety-seeking. Drawing on regulatory fit theory, this study introduces a new kind of regulatory fit based on the interaction between regulatory focus and mode (i.e., regulatory focus–mode fit), thereby extending previous work examining fit based on either regulatory focus or regulatory mode in isolation. Results from five studies, including field data from 10,547 music app consumers (text analysis), two preregistered studies, and two online experiments, show that regulatory focus–mode fit (vs. non-fit) decreases variety-seeking. Engagement and attitude certainty serially mediate regulatory focus–mode fit effects. Findings provide implications for consumer segmentation and message framing. 相似文献

To investigate the impact of the microdeletion on morphology of the prefrontal cortex in 22q11.2 Deletion Syndrome (22q11.2 DS), high-resolution, anatomic magnetic resonance imaging was performed on 19 children and adolescents with 22q11.2 DS (11 females, 8 males) and 18 unaffected controls (10 females, 8 males). Tissue volumes of the dorsolateral, dorsomedial, orbitolateral, and orbitomedial prefrontal cortex were measured. Tasks of executive function and working memory were administered to investigate the association between anatomy and function. Whole brain volume and frontal lobe tissue volume were preserved in girls but reduced in boys with 22q11.2 DS relative to age-matched controls. Dorsolateral prefrontal cortex (DLPFC) volumes were reduced in participants with 22q11.2 DS, although the gender-by-diagnosis effect found for frontal lobe was not as robust for DLPFC. DLPFC volumes were associated with performance on tasks of planning and emotional facial recognition. Longitudinal studies are needed to clarify whether gender differences in frontal lobe and DLPFC persist with development, and whether the volumes of the DLPFC are associated with eventual deterioration in adaptive/psychosocial function that may presage the onset of schizophrenia, for which individuals with 22q11.2 DS are at a disproportionately high risk. 相似文献
