When addressing infants, many adults adopt a particular type of speech, known as infant-directed speech (IDS). IDS is characterized by exaggerated intonation, as well as reduced speech rate, shorter utterance duration, and grammatical simplification. It is commonly asserted that IDS serves in part to facilitate language learning. Although…

Meyer found subjects were faster to determine if a stimulus word was a member of either of two prespecified categories if the categories were close in meaning. A reanalysis of the data favors instead a model emphasizing the role of decision-making processes in categorization and flexibility of task strategies. (CHK)

Three experiments are reported regarding reaction time. Letter comparison time was found to increase when other irrelevant letters were present, regardless of whether or not the letters made up a word or a word-like configuration. Word comparison time was found to increase when distractors were similar to targets. (Author/RM)

Semantic theory, its relationship to comprehension, the nature and function of semantic memory, and results of some research on semantic memory and bilinguals are discussed through a review of recent literature. The findings discussed seem to confirm these general observations regarding semantic memory and bilinguals: (1) there is integration and…

Examines the performance of normal and disabled readers in recognizing whether orally presented letter strings represent real words. Finds that disabled readers have difficulty in making available the full range of semantic cues when processing stimuli in an acoustic form, supporting a verbal-processing deficit hypothesis of reading disability.…

To investigate decision level processes involved in bilingual word recognition tasks, Dutch-English participants had to name Dutch-English homographs in English. In a stimulus list containing items from both languages, interlingual homographs yielded longer naming latencies, more Dutch responses, and more other errors in both response languages if…

Thirty college undergraduates participated in a study of the effects of acoustic and visual interference on the recall of word and picture triads in both short-term and long-term memory. The subjects were presented 24 triads of monosyllabic nouns representing all of the possible combinations of presentation types: pictures, printed words, and…

Four experiments are reported in which relations of semantic distance to response latencies in similarity judgments, to reaction times in a same-different classification task, and to proximity of recall in a free recall task were investigated. (Author/RM)

Two experiments are described. One measured performance of subjects on pairs of concurrent verbal tasks, monitoring sentences for certain items while reading. Secondary task performance combined with a primary task is proportional to its performance in isolation. The second experiment checked certain results of the first. (CHK)

Discusses three experiments designed to examine the problem of the internal representation of meaning of a verbal stimulus. (Text is in Italian.) (CFM)

The encoding specificity principle predicts that a change in context between input and test will adversely affect recognition memory. Experiment I tested this with sentences from a prose passage and no context effects were obtained. Experiments II, III, and IV compared context effects for words in random sentences versus connected discourse. In…

Reports on research that (1) suggests that phonetically ambiguous pairs (ice cream/I scream) have been used inaccurately to illustrate contextual effects in word segmentation, (2) supports unitary rather than exhaustive processing, and (3) supports the use of the concepts of word frequency and listener expectations instead of top-down, multiple…

Predictions were derived from the assumption that the vocabulary store underlying the auditory analysis of verbal stimuli is organized as an acoustic space rather than as a lexicon (tree) or collection. The relationship between frequency of occurrence in the language and frequency of occurrence as an error is low. (Author/SW)

Four problems in children's paired-associate memory were addressed: (1) reappraisal of the presumed developmental trend in presentation mode effect during grade-school years, (2) identification of the locus of this developmental effect, (3) evaluation of the influence of combined presentation (verbal plus pictorial) relative to pictorial…

This paper reports on two aspects of dyadic communication skills: verbal imitation, and response to questions and commands, as they relate to the development of semantic functions in three English-speaking children. The children, aged 16, 21 and 22 months, were unobtrusively videotaped during weekly free play sessions with their mothers. The…
