We evaluated the effects of response repetition (RR) as an error‐correction procedure for increasing sight‐word reading for four individuals using a multiple baseline design. The results for each participant showed that correct responding increased following the introduction of the RR procedure. In addition, responding for three of four participants showed evidence of stimulus generalization, response generalization, or both. Likewise, we found that comparable behavior changes were produced when a participant's paraprofessional implemented RR in a typical classroom. These findings are briefly discussed in terms of procedures that promote behavior acquisition and generalization via negative reinforcement. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Infants suffer to a considerable degree from disturbances in nursing, sleep, mood, and attachment. Psychotherapeutic methods are increasingly used to help them. According to case reports, psychoanalytic work with infants and mothers has shown deep‐reaching and often surprisingly rapid results, both in symptom reduction and in improved relations between mother and child. The clinical urgency of the method makes it important to study its results and theoretical underpinnings. Among the theoretical issues often raised in discussions on this modifi ed form of psychoanalysis, those addressing the nature of communication between analyst, baby, and the mother are the most frequent. For example, how and what does an infant understand when the analyst interprets to her? What does the analyst understand of the infant's communication? These issues are addressed by investigating the infant's tools for understanding linguistic and emotional communication, and by providing a semiotic framework for describing the communication between the three participants in the analytic setting. The paper also investigates problems with the traditional ways of using the concept of symbolization within psychoanalytic theory. The theoretical investigation is illustrated by two brief vignettes from psychoanalytic work with an 8 month‐old girl and her mother. demand for the breast.

Male gerbils have larger ventral scent glands, and they mark more than females. In both sexes, scent gland activity is dependent on gonadal hormones. Observations on colonies of gerbils, living in enclosures or cages, showed that both scent gland size and marking behaviour were related to social status. In colonies founded by a single pair, breeding was confined to the original female. The infertility of the daughters was due to failure of sexual maturation. As this was always associated with a lack of development of the scent glands, the functional state of the latter could be used as an index of fecundity. A change in social organization (eg removal of the parents) caused previously infertile females to conceive and was accompanied by development of the scent glands If there was competition for dominance, the scent glands of the losers regressed; at autopsy, their ovaries and uteri appeared to be nonfunctional. The founding father usually had a larger scent gland than his sons, but the inhibition of sexual function was not as severe as in the females. However, the father characteristically showed much more marking behaviow in a neutral territory than his sons. None of the fem ales-except the mother-showed appreciable marking, and her scores were much lower than those of the dominant male. Asymptotic populations were reached at about the same level in enclosures and cages, implicating an intrinsic capacity for control independent of the number of animals per unit of space but probably related to the natural size of a social group. Stabilization of numbers was achieved not only by reproductive inhibition of young females, but also by cessation of breeding by the founding mother and death of litters. Littermates raised in enclosures without their parents showed delayed sexual maturation accompanied by fighting which resulted in the formation of a hierarchy headed by a breeding female and a dominant (marking) male. 相似文献
