This article shows how to apply generalized additive models and generalized additive mixed models to single-case design data. These models excel at detecting the functional form between two variables (often called trend), that is, whether trend exists, and if it does, what its shape is (e.g., linear and nonlinear). In many respects, however, these models are also an ideal vehicle for analyzing single-case designs because they can consider level, trend, variability, overlap, immediacy of effect, and phase consistency that single-case design researchers examine when interpreting a functional relation. We show how these models can be implemented in a wide variety of ways to test whether treatment is effective, whether cases differ from each other, whether treatment effects vary over cases, and whether trend varies over cases. We illustrate diagnostic statistics and graphs, and we discuss overdispersion of data in detail, with examples of quasibinomial models for overdispersed data, including how to compute dispersion and quasi-AIC fit indices in generalized additive models. We show how generalized additive mixed models can be used to estimate autoregressive models and random effects and discuss the limitations of the mixed models compared to generalized additive models. We provide extensive annotated syntax for doing all these analyses in the free computer program R. 相似文献

Two important and related developments in children between 18 and 24 months of age are the rapid expansion of object name vocabularies and the emergence of an ability to recognize objects from sparse representations of their geometric shapes. In the same period, children also begin to show a preference for planar views (i.e., views of objects held perpendicular to the line of sight) of objects they manually explore. Are children's emerging view preferences somehow related to contemporary changes in object name vocabulary and object perception? Children aged 18 to 24 months old explored richly detailed toy objects while wearing a head camera that recorded their object views. Both children's vocabulary size and their success in recognizing sparse three-dimensional representations of the geometric shapes of objects were significantly related to their spontaneous choice of planar views of those objects during exploration. The results suggest important interdependencies among developmental changes in perception, action, word learning, and categorization in very young children. 相似文献

This essay introduces a new type of measure of social welfare, where populations are evaluated by their resemblance to an optimum population, which is an (in principle) possible population with the highest degree of social welfare, relative to some circumstances. Here, it is argued to be the largest possible population where everyone fares maximally well. The new measure is responsive to quality of welfare, equality of welfare and the number of people. It satisfies dominance and negative monotonicity, and it avoids both the repugnant conclusion and a reverse repugnant conclusion for comparisons relative to our future on earth. 相似文献

Attachment theory, developed by child psychiatrist John Bowlby, is considered a major theory in developmental psychology. Attachment theory can be seen as resulting from Bowlby's personal experiences, his psychoanalytic education, his subsequent study of ethology, and societal developments during the 1930s and 1940s. One of those developments was the outbreak of World War II and its effects on children's psychological wellbeing. In 1950, Bowlby was appointed WHO consultant to study the needs of children who were orphaned or separated from their families for other reasons and needed care in foster homes or institutions. The resulting report is generally considered a landmark publication in psychology, although it subsequently met with methodological criticism. In this paper, by reconstructing Bowlby's visit to several European countries, on the basis of notebooks and letters, the authors shed light on the background of this report and the way Bowlby used or neglected the findings he gathered. 相似文献

Gesture for generalization: gesture facilitates flexible learning of words for actions on objects 下载免费PDF全文

Verb learning is difficult for children (Gentner, 1982 ), partially because children have a bias to associate a novel verb not only with the action it represents, but also with the object on which it is learned (Kersten & Smith, 2002 ). Here we investigate how well 4‐ and 5‐year‐old children (N = 48) generalize novel verbs for actions on objects after doing or seeing the action (e.g., twisting a knob on an object) or after doing or seeing a gesture for the action (e.g., twisting in the air near an object). We find not only that children generalize more effectively through gesture experience, but also that this ability to generalize persists after a 24‐hour delay. 相似文献

This article focuses on the training of hermeneutic constructivist psychotherapists and aims to point out those aspects that make the group such a privileged place for the construction of the professional role. It hypothesized that the group, as a closed and transitory context, can promote an openness to the exploration of different alternatives and the experimentation of the professional role. The article concentrates especially on applying the psychotherapy group theory of G. A. Kelly to the group training of hermeneutic constructivist psychotherapists, describing this process through the experience cycle (Kelly, 1995) in the perspective of a transformative experience. Starting from the basic theories behind the therapeutic process, illustration will follow of the training procedure formulated to allow working with the group within a context of relationships that favor learning and experimentation of new roles. The various phases of group therapeutic training will then be illustrated. These have been formulated to enable working within the group in a relational context that favors the role of therapist construction, coming from the elaboration of certain areas of the personal system and from experimentation and the elaboration of this new role itself. 相似文献

Psychologists in academic health centers (AHC) face important ethical issues including confidentiality when working with a multidisciplinary team, sharing of information through the electronic health record, obtaining informed consent in a fast-paced healthcare environment, cultural competency in the medical setting, and issues related to supervision and training. The goal of this paper is to describe ethical issues for psychologists in AHCs in the context of case examples, and to consider ethical decision-making tools to enhance clinical care. Considerations for best practices in integrated care settings will be discussed, and the APA Ethical Standards will be referenced throughout. 相似文献
