Prompting procedures are effective for teaching skills, but limited comparative data exist to guide practitioners to select the best procedures for individuals. This study compared efficiency of two prompting procedures—constant time delay (CTD) and system of least prompts (SLP)—to teach expressive identification of 32 targets to 10 preschoolers with and without disabilities. To assess efficiency differences between conditions and analyze changes in learning over time, we used adapted alternating treatments designs in the measurement context of cumulative records. CTD was more efficient for five children, SLP was more efficient for three children, and results were inconclusive for two children. We measured children’s choices between procedures via simultaneous treatments designs, to assess child preference and whether preferences and efficiency aligned. Preference outcomes were mixed and did not consistently align with efficiency. We used exploratory analyses to assess whether child characteristics moderated outcomes. Children for whom CTD was more efficient had significantly fewer sessions to mastery, non-significantly fewer errors, and non-significantly higher developmental assessment scores, compared to children for whom SLP was more efficient.

The relationship between mother-infant interaction and interactive communication competence in high-risk and developmentally-delayed children is examined and an inter vention program that attempts to optimize mother-infant interaction is described. Interaction patterns in populations with atypical infants are consistently found to be different from those in families with normally developing infants. The risk and delayed infants show fewer, less intense, and developmentally-delayed social responses and their mothers compensate with more frequent and often intensive forms of social interaction. An intervention model is presented that (1) evaluates the mother on a hierarchy of interaction styles that range from low to high levels of sensitivity and (2) modifies interaction style through the use of easy-to-learn techniques with the goal of moving the mother to an optimal level in the defined hierarchy of social behavior. 相似文献
The editors of the JRE solicited short essays on the COVID-19 pandemic from a group of scholars of religious ethics that reflected on how the field might help them make sense of the complex religious, cultural, ethical, and political implications of the pandemic, and on how the pandemic might shape the future of religious ethics. 相似文献
Suffering is a ubiquitous yet elusive concept in health care. In a field devoted to the pursuit of objective data, suffering is a phenomenon with deep ties to subjective experience, moral values, and cultural norms. Suffering’s tie to subjective experience makes it challenging to discern and respond to the suffering of others. In particular, the question of whether a child with profound neurocognitive disabilities can suffer has generated a robust discourse, rooted in philosophical conceptualizations of personhood as well as the academic and experiential expertise of practiced health-care professionals. The issue remains unresolved because it is difficult, perhaps impossible, to ever truly know an infant’s lived experience. But what if this is not the best question? What if instead of asking “can this infant suffer?” the discourse is broadened to ask “is there suffering here?” This latter question demands attention to patients’ subjective experiences of suffering, but also to the web of relationships that envelop them. Without losing sight of the importance of patients’ experiences, consideration of their relationships may elucidate the presence of suffering when the patients themselves are unable to provide the same clarity. In this essay, care ethics frames an examination of how suffering manifests in the loving and caring relationships that surround an infant with profound neurocognitive disabilities, changing those relationships and affecting the individuals within them. Exploring suffering through these relationships may offer clarity on the presence and content of suffering for infants with profound cognitive disabilities, in turn offering moral guidance for responding to suffering and supporting flourishing in this context.
Summary In this study the role of perceptual and motor factors on the motor organization (integrated versus parallel) adopted by musically skilled and unskilled subjects in a polyrhythmic tapping task was investigated. Subjects tapped a 3:2 polyrhythm to match the timing of two isochronous tone trains, one tone train for each hand. Perceptual factors were examined by the manipulation of the frequency difference between the tone trains to produce either an integrated or a streamed percept. Motor factors were examined by comparison of performance on two versions of the 3:2 polyrhythm. In one (simultaneous) version, each cycle of the polyrhythm began with a simultaneous left- and right-hand tap. In the other (shifted) version a 100-ms interval was introduced between the initial left and right taps in each cycle. Examination of the pattern of variances and covariances among intertap intervals suggested that most of the subjects in this study adopted an integrated motor organization that involved interleaving the timing of the two hands. Further analysis revealed that a serial chained model described the pattern of covariances best for the simultaneous pattern, whereas a hierarchical organization described the pattern of covariances for the shifted pattern best. The finding that performance was more accurate with integrated tones than with streamed tones provides some support for a perceptual-motor facilitation hypothesis. 相似文献
Eudaimonism is often regarded as egoistic. If it recommends that agents pursue their own good because it is their own good, it is guilty as charged. But excellence‐prior eudaimonism offers a non‐egoistic alternative to this welfare‐prior eudaimonism. Excellence‐prior eudaimonism recommends that an agent live in a way that is in fact good for the agent, but it does not regard the agent’s own good as necessarily that for the sake of which the agent acts, nor does it regard living well as justified by the fact that it is good for the agent, but simply because it is good. The Christian eudaimonisms of Augustine and Aquinas are best understood as deepened forms of excellence‐prior eudaimonism. 相似文献
In experiment 1, pigeons were trained to match temporal (2, 8, and 10 s of houselight) and location (feeder light, left key,
center key illumination) samples to color comparison stimuli. Red choices were correct following the 2-s and feeder light,
orange choices were correct following the 8-s and center key, and green choices were correct following the 10-s and left key.
Samples that were harder to discriminate (8- vs 10-s, and left vs center key) were mapped onto comparisons that were easy
to discriminate (orange vs green), while samples that were easier to discriminate (2- vs 8-s, and feeder light vs left key)
were mapped onto comparisons that were hard to discriminate(red vs orange). The pattern of errors for temporal and location
samples indicated that these samples were not represented by a common code even though they were associated with the same
comparison stimuli. In experiment 2, the same pigeons were trained with visual samples in which samples that were hard to
discriminate (triangle vs circle) were mapped onto comparisons that were easy to discriminate (orange vs green), while samples
that were easy to discriminate(plus vs triangle) were mapped onto comparisons that were hard to discriminate (red vs orange).
Following acquisition of the visual discrimination, the temporal samples were re-introduced and many-to-one training was continued.
During delay testing, the pattern of errors for temporal and visual samples was equivalent and consistent with the hypothesis
that visual samples were being coded in terms of the duration appropriate for the temporal sample with which it shared a common
comparison response. Data from no-sample test sessions ruled out a simple response bias explanation of the data. The properties
of common codes for temporal and nontemporal events can be somewhat flexible and more complicated than previously envisaged.
