Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

The authors of this current study compared the memory performance of adolescent students with specific reading disabilities (RD) with that of typical adolescent readers on a newly developed verbal learning test, the "Bergen-Tucson Verbal Learning Test" (BTVLT). This multiple trial test was designed to measure memory acquisition,…

Investigated was the development of the process whereby 63 deaf children (9-14 years old) attended to the orthographic structure of tachistoscopically presented verbal materials. (Author/DB)

Studies the effect of phonetic compatibility upon verbal learning and concludes that it is a task variable of considerable magnitude. (WY)

The verbal encoding ability of 24 students (ages 14-20) with learning disabilities (LD) was compared to that of 24 non-learning-disabled subjects. LD subjects did not show a release from proactive interference, suggesting that such students are less likely to encode the phonetic features of words or use a phonetic code in short-term memory.…

Phonetic symbolism implies that there are intrinsic relationships between sounds employed in words and the meanings of the words. Research in phonetic symbolism and how it operates has implications for foreign language learning. Such research seeks to determine whether one's capacity for correctly guessing the meanings of words in another language…

Infants parse speech into word-sized units according to biases that develop in the first year. One bias, present before the age of 7 months, is to cluster syllables that tend to co-occur. The present computational research demonstrates that this statistical clustering bias could lead to the extraction of speech sequences that are actual words,…

This document is the seventh report in the Language Research in Progress (LRIP) series, and lists a wide variety of language-related research projects current between April 1968 and November 1968. Research projects terminated in the six months prior to publication are included as well. Approximately 250 projects in the U.S. and abroad are…
