During feature-positive operant discriminations, a conditional cue, X, signals whether responses made during a second stimulus, A, are reinforced. Few studies have examined how landmarks, which can be trained to control the spatial distribution of responses during search tasks, might operate under conditional control. We trained college students to search for a target hidden on a computer monitor. Participants learned that responses to a hidden target location signaled by a landmark (e.g., A) would be reinforced only if the landmark was preceded by a colored background display (e.g., X). In Experiment 1, participants received feature-positive training (+←YB/ XA→+/A?/B?) with the hidden target to the right of A and to left of B. Responding during nonreinforced transfer test trials (XB?/YA?) indicated conditional control by the colored background, and spatial accuracy indicated a greater weighting of spatial information provided by the landmark than by the conditional cue. In Experiments 2a and 2b, the location of the target relative to landmark A was conditional on the colored background (+←YA/ XA→+/ ZB→+/ +←C /A?/B?). At test, conditional control and a greater weighting for the landmark’s spatial information were again found, but we also report evidence for spatial interference by the conditional stimulus. Overall, we found that hierarchical accounts best explain the observed differences in response magnitude, whereas spatial accuracy was best explained via spatial learning models that emphasize the reliability, stability, and proximity of landmarks to a target. 相似文献

This study examined the relative contributions of phonological awareness, orthographic pattern recognition, and rapid letter
naming to fluent word and connected-text reading within a dyslexic sample of 123 children in second and third grades. Participants
were assessed on a variety of fluency measures and reading subskills. Correlations and hierarchical multiple regression analyses
were carried out to explore these relationships. The results demonstrate that phonological awareness, rapid letter naming,
and orthographic pattern recognition contribute to word-reading skills. Furthermore, rapid naming, orthographic pattern recognition,
and word reading fluency moderately predict different dimensions of connected-text reading (i.e., rate, accuracy, and comprehension)
whereas phonological awareness contributes only to the comprehension dimension of connected-text reading. The findings support
the multidimensional nature of fluency in which the whole is more than its parts. 相似文献

There is a global trend towards including children with special needs in mainstream schools instead of placing them in special schools. However, the numbers of students in special schools varies greatly among regions due to variations in educational systems, funding arrangements – and the incentives that are associated with these arrangements – and demographic trends. In the Netherlands, a new policy aimed at inclusive education was introduced in 2014, together with financial measures to equalise funding for students with special needs across the country. The present study explored the effects of this equalisation policy, as well as the demographic trend of population decline, on dropout rates and participation rates in special education (namely, special schools for mainstream education and schools for special education). The data were retrieved from nation-wide registration systems. The results showed that population decline did not affect participation rates in special education, whereas decreases in funding did result in greater declines in participation rates in special education. Moreover, decreases in funding also resulted in higher dropout rates in areas with growing student populations. Although the reform of funding arrangements resulted in lower participation in special education, higher dropout rates might be a cost of this shift towards inclusive education. 相似文献
