Increased attention has been directed recently to assisting persons with severe handicaps to express preferences concerning events in their lives. We evaluated a program for assessing choice-making skills to provide opportunities for persons with profound mental retardation to express food and drink preferences. In Experiment 1, the assessment procedure involving repeated, paired-item presentations resulted in active choice making and the identification of preferences for all 5 participants. Results also indicated that caregiver opinion was not predictive of participant food and drink preferences. A survey of service providers supported the importance of meal-related choices in this population. In Experiment 2, the practicality of the assessment procedure was supported by demonstrating that (a) routine caregivers could apply the procedure with appropriate supervision to provide choice opportunities, and (b) results of the procedure were predictive of participant choices when a less structured and more normal opportunity to express a preference was provided during regular mealtimes. Results are discussed in terms of extending the developing technology of preference and reinforcer identification to other important areas for persons with severe disabilities. 相似文献

We evaluated the effects of several choice-related variables on the work performance of adults with severe handicaps. After assessing client work preferences, three choice-related situations were presented: (a) providing clients with the opportunity to choose a work task, (b) assigning a preferred task, and (c) assigning a nonpreferred task. Results indicated that clients attended to work tasks almost twice as much when they chose their tasks and when assigned to work on preferred tasks versus when assigned to work on nonpreferred tasks. Results are discussed regarding the need to assess systematically the effects of choice-related variables. 相似文献

Despite increased recognition of the importance of providing routine choice opportunities for persons with severe handicaps, this population continues to experience a typical lack of such opportunities. We evaluated a program for increasing the amount of choices made during routine mealtimes by persons with profound mental retardation and minimal communication skills. The choice provision program, involving systematic presentation of alternative food and drink items in a step-wise fashion during the course of the meal, was implemented with three persons in a residential facility. Results indicated that after implementation of the choice program, all three participants made consistently more choices concerning the foods and beverages they consumed relative to baseline. The choice provision program was conducted without extending the amount of time typically allotted to mealtime within the residential setting. Results are discussed in regard to additional research needed to continue developing means of assisting persons with profound mental retardation to exert control over meaningful events in their lives. 相似文献

We reconcile competing theories of the role of phonological memory in reading development, by uncovering their dynamic relationship during the first 5 years of school. Phonological memory, reading and phoneme awareness were assessed in 780 phonics‐educated children at age 4, 5, 6 and 9. Confirmatory factor analyses demonstrated that phonological memory loaded onto two factors: verbal short‐term memory (verbal STM; phonological tasks that loaded primarily on serial order memory) and nonword repetition. Using longitudinal structural equation models, we found that verbal STM directly predicted early word‐level reading from age 4 to 6, reflecting the importance of serial‐order memory for letter‐by‐letter decoding. In contrast, reading had no reciprocal influence on the development of verbal STM. The relationship between nonword repetition and reading was bidirectional across the 5 years of study: nonword repetition and reading predicted each other both directly and indirectly (via phoneme awareness). Indirect effects from nonword repetition (and verbal STM) to reading support the view that phonological memory stimulates phonemically detailed representations through repeated encoding of complex verbal stimuli. Similarly, the indirect influence of reading on nonword repetition suggests that improved reading ability promotes the phoneme‐level specificity of phonological representations. Finally, the direct influence from reading to nonword repetition suggests that better readers use orthographic cues to help them remember and repeat new words accurately.

In a follow-up study of over 17,000 individuals born 12 years apart (in 1958 and 1970) this article investigates the formation and realization of teenage career aspirations in a changing sociohistorical context. Two types of analytical models, a mediating model and a contextual systems model, were used to analyze the processes by which the effects of social structure influence teenage aspirations and subsequent occupational attainment. Both models suggest that teenage aspirations in combination with educational attainments are a major driving force in the occupational development of young people and that they mediate the effects of socioeconomic background factors. The contextual system model is an elaboration of the mediating model, providing additional insights into the effects of distal and proximal contexts. Differences in the experiences of young people growing up 12 years apart indicate that the sociohistorical context plays a key role in shaping occupational progression. For the later born cohort the importance of educational credentials has increased, both in influencing teenage aspirations and predicting adult occupational outcomes. 相似文献
