This paper discusses variation in reasoning strategies among expert mathematicians, with a particular focus on the degree to which they use examples to reason about general conjectures. We first discuss literature on the use of examples in understanding and reasoning about abstract mathematics, relating this to a conceptualisation of syntactic and…

The Internet and growth of computer networks have eliminated geographic barriers, creating an environment where education can be brought to a student no matter where that student may be. The success of distance learning programs and the availability of many Web-supported applications and multimedia resources have increased the effectiveness of…

A study of 21 patients with Alzheimer's Disease and 25 with vascular dementia, the two most common forms of dementia, investigated language impairments in the dementia syndrome to see if analysis of language disturbances is helpful in differential diagnosis. Diagnostic assessment included a neurological examination, detailed medical history,…

Findings suggest that semantic knowledge for concrete objects is represented and organized in similar ways in autistic, retarded, and normal children. Previous findings on cognitive deficits in autistic children are more likely related to their inability to use cognitive representations in an appropriate and flexible manner. (Author/RH)

Alcoholism is an almost universal problem which varies in nature and extent from culture to culture. To discriminate between French and American students on the basis of measured attitudes toward alcohol, American college students (N=291) and French college students (N=308) completed attitude measures for alcohol derived from a 14 scale semantic…

This paper examines the tacit assumptions behind different theories about the nature of language and aphasia, and it discusses critically the use of structural and generative linguistic theories to explain the behavior of aphasics, especially with regard to the difference between spoken and written discourse. It is proposed that, rather than try…

Investigates the extent to which learning disabled readers' atypical encoding relates to their deficiencies in semantic memory by comparing learning disabled and nondisabled readers in two age groups on dichotic listening tasks that included orienting and nonorienting instructions. (HOD)

This article on sampling early semantic productions reports a study of 6 children (ages 31-35 months) with specific language impairments. Subjects produced a greater frequency and diversity of multiword utterances in a free-play sampling situation than in a joint action routine sampling situation. (JDD)

An analysis of Korean language textbooks currently used by Korean children and of nationally-administered reading comprehension test items for high school graduates reveals a text-oriented reading comprehension approach in South Korea. Text orientation--seeing individual words, phrases, and sentences as semantically unified into a meaningful…
