Functional analyses sometimes do not identify momentary fluctuations in the function of destructive behavior (Bowman, Fisher, Thompson, & Piazza, 1997). In such cases, individuals may mand for the reinforcer that is currently most preferred and display destructive behavior if that mand goes unreinforced. In this study, we conducted a mand analysis to test whether destructive behavior functioned as a precurrent response that increased reinforcement for the participant's mands. We then evaluated a treatment that matched this function of destructive behavior by providing differential or time-based reinforcement of participant mands in accordance with multiple or chained schedules with reinforcement-schedule thinning. Decreases in destructive behavior averaged 97.4% across cases. We discuss these results relative to the importance of matching treatments for destructive behavior to operant functions for both traditional and idiosyncratic functions of destructive behavior. 相似文献

Head orientation was investigated in a longitudinal study of 37 infants, who were observed at ages 2, 4, 8, and 12 weeks, during a 60-second period that followed each of four (60 second) midline or lateral holds. When newborn, the infants tended to lie with their heads to the right, but this bias weakened over the first 3 postnatal months. This rightward motor bias was constrained further by such factors as sex and holding position; both factors had their strongest effect at 8 weeks. Finally, evidence was found for behavioral reorganization of postural orientation such that head orientation was less influenced by prior head positioning after than prior to 8 weeks. 相似文献

Recent studies have found significant but relatively modest associations in parenting across generations, suggesting additional influences on parenting beyond experiences in the family of origin. The present prospective, cross-generational study of at-risk men (Oregon Youth Study) focuses on fathers' negative discipline practices with their 2- to 3-year-old children. The theoretical model is based on a dynamic developmental systems approach to problematic family functioning, which points to the importance of developmental systems, including family risk context and key influential social interactional systems, and emphasizes influence that is directly pertinent to the outcome of interest. Path modeling indicated that the men's poor and harsh discipline practices were predicted by partners' problem behavior (substance use and antisocial behavior) and negative discipline practices, as well as by poor discipline experienced in the family of origin; men's own problem behavior, ages at which they became fathers, and family socioeconomic status were controlled. Findings indicate the importance of focusing on influence dynamics across parents. 相似文献

Ocular pursuit movements allow moving objects to be tracked with a combination of smooth movements and saccades. The principal objective is to maintain smooth eye velocity close to object velocity, thus minimising retinal image motion and maintaining acuity. Saccadic movements serve to realign the image if it falls outside the fovea, the area of highest acuity. Pursuit movements are often portrayed as voluntary but their basis lies in processes that sense retinal motion and can induce eye movements without active participation. The factor distinguishing pursuit from such reflexive movements is the ability to select and track a single object when presented with multiple stimuli. The selective process requires attention, which appears to raise the gain for the selected object and/or suppress that associated with other stimuli, the resulting competition often reducing pursuit velocity. Although pursuit is essentially a feedback process, delays in motion processing create problems of stability and speed of response. This is countered by predictive processes, probably operating through internal efference copy (extra-retinal) mechanisms using short-term memory to store velocity and timing information from prior stimulation. In response to constant velocity motion, the initial response is visually driven, but extra-retinal mechanisms rapidly take over and sustain pursuit. The same extra-retinal mechanisms may also be responsible for generating anticipatory smooth pursuit movements when past experience creates expectancy of impending object motion. Similar, but more complex, processes appear to operate during periodic pursuit, where partial trajectory information is stored and released in anticipation of expected future motion, thus minimising phase errors associated with motion processing delays. 相似文献

Occurrence and recurrences of suicidal ideation (SI) were modeled among boys/men assessed annually from ages 12 to 29 years. Multiple-spell discrete-time event-history analyses permitted (a) determination of whether risk for SI escalates with prior experiences of SI (spell effects), while (b) accounting for changes in risk with time (period effects) and (c) controlling for vulnerability factors. Self-reported SI (presence/absence in past week), depressive symptoms, alcohol/substance use, antisocial behavior, and official arrest records were collected annually from 205 boys recruited on the basis of community risk for delinquency. Parents' self-reported psychopathology and SES were collected in childhood. Period effects supported decreasing risk for SI over time. Spell and time-varying 1-year lagged substance use and depressive symptoms independently predicted increased risk for SI. Models involving SI with intent were explored. Consistent with interpersonal psychological theory, risk for young men's SI increases with past experience of SI, even with key propensities controlled. However, risk also decays over time. Targeting conditions that confer risk for SI is essential. Preventing and delaying SI occurrence and recurrence may represent independent mechanisms by which prevention efforts operate. 相似文献

Increased hypothalamic-pituitary-adrenal (HPA) activation, culminating in elevated circulating cortisol levels is a fundamental response to stressors. In animals, this neuroendocrine change is highly reliable and marked (approximately 5-10-fold elevations), whereas in humans, the increase of cortisol release is less pronounced, and even some potent life-threatening events (anticipation of surgery) only elicit modest cortisol increases. Meta-analysis of factors that influenced the increase of cortisol release in a laboratory context pointed to the importance of social evaluative threats and stressor controllability in accounting for the cortisol rise. The present meta-analysis, covering the period from 1978 through March 2007, was undertaken to identify the factors most closely aligned with cortisol increases in natural settings. It appeared that stressor chronicity was fundamental in predicting cortisol changes; however, this variable is often confounded by the stressor type, the stressor's controllability, as well as contextual factors, making it difficult to disentangle their relative contributions to the cortisol response. Moreover, several experiential factors (e.g. previous stressor experiences) may influence the cortisol response to ongoing stressors, but these are not readily deduced through a meta-analysis. Nevertheless, there are ample data suggesting that stressful events, through their actions on cortisol levels and reactivity, may influence psychological and physical pathology. 相似文献

The aim of this paper is to articulate a new ‘post‐liberal’ paradigm for religious education in Britain. As criticisms of British religious education have mounted over the last few decades, it is becoming increasingly obvious that familiar inherited ways of conceptualising the nature and practice of religious education in schools are inappropriate to contemporary educational needs. A new model is required to structure, justify and direct learning and teaching in religious education. This paper reviews the commitments, assumptions and beliefs that together constitute the current ruling ‘liberal’ paradigm, identifies and exposes its weakness and concludes by providing a tentative first draft of a new ‘post‐liberal’ paradigm for religious education, which holds more promise of realising socially positive educational aims than the current paradigm. 相似文献

This essay argues that without allowing for a legitimate extra‐biblical reasoning for the appropriateness of God's “simplicity,” Christians will be compelled biblically to affirm that God, as such, has a body — or at least Christians will have to accept this as a theologically possible reading of Scripture that cannot be ruled out. Barnes first cites ancient philosophical sources that argue that God has no parts but is utterly simple. In Barnes's quick sketch, the main role is given to Plotinus and especially to the summation found in Alcuinus's Didaskalon X.7 (Alcuinus is known also as Albinus). Barnes then examines readings of Israel's Scriptures that indicate the bodiliness of God (YHWH). Most importantly, divine bodiliness comports with the “plain sense” of Scripture. Here he draws upon such works as Benjamin Sommer's The Bodies of God, Stephen Moore's “Gigantic God,” and Tryggve Mettinger's The Dethronement of Sabaoth; and he also makes reference to the work of the Jewish kabbalist scholar Gershom Scholem. Barnes carefully investigates such passages as Exodus 33, in which God is clearly presented as having bodily parts, including a “face.” As Barnes notes, the Fathers’ arguments for why God does not have a body are tied completely to their arguments for why God exists simply. 相似文献
