From a group of 75 children, originally selected as dyslectic on the basis of their reading and/or spelling problems relative to a total group of 1000 4.th grade children in the city of Trondheim, blood tests were obtained on 35 children. A control group of 45 children was drawn among the 1000 children. Among the 12 different hormones measured, significant differences came out on cortisol, triiodothyronine (T. 3), prolactin, and human growth hormone (HGH, somatotrophin) in boys and girls separately. A follow-up study of 22 dyslectic children from the same cohort gave results consistent with those obtained in the original study. The higher values of the dyslectic group on cortisol and prolactin may suggest the dyslectics to be in a stressful situation, possibly due to their language problems in school. The most striking difference, however, was the very low levels of HGH in the dyslectic group—to the extent that there was little overlap in the two distributions. This result was totally unexpected and is, in fact, opposite of what to be expected on the basis of at least short — time stress events. The results holds up when age and pubery development are controlled for. 相似文献

Are sophisticated students always better? The role of topic-specific personal epistemology in the understanding of multiple expository texts 总被引:1,自引:0,他引:1

In a sample of 135 Norwegian education undergraduates, we examined the effects of topic-specific epistemic beliefs concerning the simplicity and source of knowledge on deep-level understanding of multiple expository texts about the same topic—climate change. The results showed that students holding sophisticated simplicity beliefs, viewing knowledge about climate change as complex, gained better multiple-text understanding than did students holding naïve simplicity beliefs, viewing knowledge about climate change as simple. However, students holding sophisticated source beliefs, viewing knowledge about climate change as personal construction, performed poorer than did students holding naïve source beliefs, viewing knowledge about climate change as transmitted from experts. Moreover, students believing knowledge to be complex and, simultaneously, relying on expert authors were at a particular advantage with respect to multiple-text understanding. Thus, in this complex reading-task context, source beliefs usually located at the sophisticated ends of epistemic belief continuums turned out to be maladaptive, presumably because they distracted from the building of a high-quality representation of author and text meaning. 相似文献

TJ, a 10‐years, 7‐months‐old spelling‐disabled boy suffering from aphasia, was exposed to a spelling remediation programme introduced in the autumn term of Grade 4 and concluded in the spring term of Grade 6. A systematic strategy instructional approach was used to teach the boy 65 phonetically irregular words. The remedial spelling programme was successful in developing appropriate spelling strategies which were applied to the processing of these words and maintained at follow‐up at 2 months. Generalisation of programme effects was shown on standardised spelling tests administered during training. However, the programme did not seem to be very successful in lessening the disparity between the boy's spelling performance and average spelling performance for his grade. It was concluded that spelling‐disabled students suffering from neurological impairment probably need more cumulative training than other spelling‐disabled students. The potential role of a verbally orientated strategy approach in spelling remediation was also discussed in relation to a visually orientated approach. 相似文献

Rats (n=6) visited four baited locations (randomly chosen on each trial; study phase), one of which was randomly selected to provide
chocolate. After short (1-h) or long (25-h) retention intervals (RIs), eight locations were available, and the four locations
not available in the study phase provided food (test phase); the chocolate location also provided food after long RIs. More
visits to the chocolate location occurred after long RIs than after short RIs. Next, chocolate was paired with LiCl during
the long RI (i.e., after encoding the chocolate location). Fewer revisits to the chocolate location occurred after LiCl than
in previous testing with the long RI. The rats demonstrated complete transfer when grape replaced chocolate after LiCl-chocolate
pairing. The discrimination of what, when, and where could not be based on adopting different revisit strategies at different
times of testing. 相似文献
