AbstractTo evaluate whether frequent interactive tablet-use at preschool age is associated with improved fine motor skills and to describe tablet-use in young children. Cross-sectional study with 78 children, aged 24–42?months: group 1 with previous frequent tablet-use exposure (n?=?26), group 2 without previous tablet-use exposure (n?=?52). Fine motor skills were evaluated with the Bayley-III. Socioeconomic data and home environment quality were similar in both groups. Fine motor skills of group 1 were better than those of group 2 (p?=?0.013). Most participating children carried out passive and active tablet activities, usually accompanied by parents, not exceeding time recommendations for young age. We observed a difference in fine motor skills in young children slightly favoring those with tablet-use experience. 相似文献

In congenitally or prelingually deaf childrencochlear implantation is open to seriousethical challenge. The ethical dimension ofthis technology is closely related to both asocial standard of quality of life and to theuncertainty of the overall results of cochlearimplantation. Uncertainty with regards theacquisition of oral communicative skills.However, in the western world, available datasuggest that deafness is associated with thelowest educational level and the lowest familyincome. Notwithstanding the existence of aDeaf-World, deafness should be considered as ahandicap. Therefore, society should provide themeans for the fulfilment of a deaf child'sspecific needs.For the time being there is no definitiveanswer with regard the best way to rehabilitatea particular deaf child. Therefore,communitarian values may be acceptable. If thedeaf child parents' decide not to implant,their decision should be respected. Guardiansare entitled to determine which standard ofbest interest to use in a specificcircumstance. They are the proper judges ofwhat (re)habilitation process is best for theirdeaf child. However, most deaf children areborn to two hearing parents. Probably, theywill not be acculturated in the Deaf-World. Itfollows that cochlear implantation is awelcomed (re)habilitation technology.If auditory (re)habilitation will in the futureprovide the necessary communicative skills, inparticular oral language acquisition, customs,values and attitudes of the hearing worldshould be regarded as necessary to accomplish adeaf child's right to an open future. Ifcochlear implantation technology will provideall deaf children with the capacity to developacceptable oral communicative skills –whatever the hearing status of the family andthe cultural environment – then auditory(re)habilitation will be an ethical imperative. 相似文献

Most studies of operant conditioning of infant vocalization do not fully use the experimental-analysis-of-behavior methodology that behavioral researchers have developed to study operant phenomena. This could be a contributing factor in their failure to correctly operationalize the definition of reinforcement, severely limiting the amount of information they can provide about operant learning in infants. Furthermore, single-subject-design studies may be added to supplement or replace group experimental designs in the study of infant vocal conditioning if we are to recognize the different learning processes that affect infant learning. Finally, single-subject experimental designs may be crucial to the development of an effective technology of early language intervention. 相似文献

A change in the size of a fixed-ratio schedule involves a simultaneous change in number of responses, in time to complete the ratio (work time), and in the interval between successive reinforcements (interreinforcement interval). Previous studies have suggested the importance of work time and the interreinforcement interval in controlling the length of the post-reinforcement pause. The present study sought to determine whether number of responses is also a significant factor. Pigeons were trained on a multiple fixed-ratio x fixed-ratio 2 plus timeout schedule in which the size of the fixed-ratio x was manipulated. When the work times (Experiment I) or interreinforcement intervals (Experiment II) were equated for the two components, the pause before the fixed-ratio x was longer than the pause before the fixed-ratio 2 plus timeout. As fixed-ratio x size increased, the relative difference in the lengths of the two types of pauses also increased. Because the fixed-ratio x component contained a larger number of responses than the fixed-ratio 2 plus timeout component, the relatively longer pause preceding the fixed-ratio x indicates that number of responses played a significant role in determining the length of the post-reinforcement pause. 相似文献

Recent research indicates the presence of an age-related visual processing deficit, for which the elderly may attempt to compensate
through the use of relational information. This hypothesis was tested, using the category superiority effect as a model system.
In studies of young adults, the category superiority effect has been shown to be confined to relatively abstract stimulus
materials, such as verbal items, and to be absent for pictures. However, it was predicted that a category superiority effect
would be present in elderly adults both for verbal and for pictorial stimuli, since the elderly would be expected to utilize
category information to compensate for imagerie deficits. This prediction was confirmed, consistent with the hypothesis advanced
above. It was further suggested that the establishment of a prior framework for recall, based on relational information, would
reduce this effect significantly. This prediction was also confirmed.
