In this study we explore listeners' sensitivity to vowel to vowel (VV) coarticulation, using both event-related potential (ERP) and behavioral methodologies. The stimuli used were vowels "colored" by the coarticulatory influence of other vowels across one, three or five intervening segments. The paradigm used in the ERP portion of the study was…

A proportion of children with visual impairments have specific reading difficulties that cannot be easily explained. This article reviews the data on problems with braille reading and interprets them from the framework of the temporal-processing deficit theory of developmental dyslexia.

Discusses communicational aspects of Rorschach data. (RS)

The four papers in this collection discuss language perception and comprehension and report on experiments in those areas. The first paper, "The Influence of Non-Linguistic Knowledge on Perceiving and Verifying Sentences," discusses the reliance of language perception and comprehension on the interaction of linguistic and world…

Examines the perception of components of written and spoken codes of human communication from a broad perspective in an attempt to identify possible similarities. (GT)

Morse code signals were presented dichotically to Morse code operators and to naive subjects with no knowledge of Morse code. The operators showed right ear superiority, indicating left hemisphere dominance for the perception of dichotically presented Morse code letters. Naive subjects showed the same right ear superiority when presented with a…

The experiment described in this report investigates the effects of various cognitive cues in questions asked regarding the relationship of elements in pictorial depth perception. The subjects of this study are 40 third grade Black and Puerto Rican children. They are confronted with four pictures from the Hudson Depth Perception Tests and asked to…

Cognitive mechanisms underlying repetition priming in picture naming were decomposed in several experiments. Sets of encoding manipulations meant to selectively prime or reduce priming in object identification or word production components of picture naming were combined factorially to dissociate processes underlying priming in picture naming.…

The purpose of this research project is to specify critical events within a person during linguistic processing. The experiments reported here cover such topics as the effects of increased reading rate on covert processes, covert behavior as a direct electro-myographic measure of mediating responses, enhancement of speech perception by…

Research reports on the nature of speech, instrumentation for the investigation of speech, and practical applications of speech research are presented in this status report. The 18 reports deal with a variety of topics, including the following: (1) cyclic production of vowels in sequences of monosyllabic stress feet; (2) differences between…

Research into the psychology of perception can uncover important discoveries for more efficient learning. There must be increased understanding of the processing of input and the pre-processing of output for improved language instruction. Educators must at the present time be extremely wary of basing what they do in the foreign-language classroom…

Individual differences in dichotic fusion experiments could be based on a number of different principles. The current working hypothesis suggests that the phenomenon reflects a language-binding effect; language-bound (LB) individuals perceive and remember events in language terms while language-optional (LO) individuals can use language structures…

Discusses connectionist techniques that can be used for modeling perception, memory, and language processing, concentrating on a class of network with dual-weight connections in which each connection has both short- and long-term weight and describes a novel architecture in which the short- and long-term weights are independent. (45 references)…

Reviews how second-language acquisition (SLA) research appeals to ideas of attention and distinguishes among attention, awareness, and consciousness. Suggests how problems in SLA might be investigated through an alliance of SLA insights with those of the cognitive literature on attention. (Contains 90 references.) (JP)
