This study presents an empirical investigation of basic processes in the perception of speech sounds. The experimental methods applied have their roots in two different psycholinguistic research paradigms; i.e., "categorical perception" and "dichotic listening." In the categorical perception paradigm, listeners' categorization…

Two studies investigated how components of speaking rate, articulation rate and pause rate, combine to influence processing of the silence-duration cue for the voicing distinction in medial stop consonants. Listeners adjust for both articulation rate and pause rate changes in articulation rate had more effect on phonetic judgments. (Author/RD)

A study employed computational and experimental methods to address a number of issues related to the representation and structural organization of spoken words in the mental lexicon. Using a computerized lexicon consisting of phonetic transcriptions of 20,000 words, "similarity neighborhoods" for each of the transcriptions were computed.…

It is proposed in this paper that a developmental continuum functions between metaphors and the perception of metaphoric referents in both ordinary and aesthetic language use, and three levels of the metaphoring act are isolated: perceptual, analogical, and evaluative. These levels appear justified in terms of their functional association with…

Two experiments tested the limiting case of a multiple resources approach to resource allocation in information processing. Results contradict a single-capacity model, supporting the idea that the hemispheres' resource supplies are independent and have implications for both cerebral specialization and divided attention issues.

A study investigated at what point during eye fixations visual information is used in furthering the reading process. The study identified two aspects of information processing: registration, in which a light pattern on the retina triggers a pattern of neural activity in the visula cortex; and utilization, in which the registered pattern has an…

Summarizing research activities from October 1978 to August 1979, this is the fifth annual report of research on speech processing conducted in the Department of Psychology at Indiana University. The report includes extended manuscripts, short reports, progress reports, and information on instrumentation developments and software support. The…

Suggests that thematic roles might best be viewed as verb-specific concepts and that this conceptual/world knowledge is computed and used immediately in online language processing. Discusses results in relation to other recent treatments of thematic roles as well as constraint-based and garden path models. (68 references) (Author/CK)

Thirty-six college students read a portion of a contemporary novel presented on a cathode ray tube while their eye movements were being monitored and recorded in an effort to determine how soon after the onset of a fixation during reading the mind begins to deal with characteristics of the language being perceived. The passage contained a total of…

A study explored whether cues given in advance of messages presented through noise were effective for increasing comprehension. Specifically, the study examined whether (1) relevant cues increased overall listening accuracy and (2) irrelevant cues impaired listening by introducing distortions into the processing of messages or simply decreased the…

A study investigated the process of information extraction in reading in order to determine whether language constraints in texts reduced the amount of visual detail noticed by the reader during the reading of specific words. A detailed examination was made of 20 college students' eye movement patterns as they read a group of selected passages.…

Hypothesizes that the human brain localizes mental operations which are integrated in the performance of cognitive tasks such as reading. Provides support of this hypothesis from studies in neural imaging, mental imagery, timing, and memory. (RT)

Twenty reading-disabled, 10 math-disabled, and 25 control-group college students were assessed on a battery of psychophysical tasks that included 5 tests of temporal processing. Findings suggest that poor temporal processing is neither a necessary nor a sufficient cause of reading disability but that there is a modest association between the two…

Illustrates how one can discover structure in mental abilities where none was obvious. Reports that two classes of processes are used to form images. Indicates that imagery is carried out by multiple processes, not all of which are implemented equally effectively in the same part of the brain. (RT)

A multiple choice Metaphor Preferences Test was administered to 138 preschool through college subjects to determine the role of a metaphor's ground in determining a metaphor's appeal, and to document the evolution of preferences for different types of grounds. Ground is the common property that links the two terms of a metaphor (topic and…
