In this study, the authors used a dual-task flanker paradigm to investigate the degree to which flankers are coprocessed with the target as a function of whether flankers have to be used as stimuli for a second task. A series of experiments, in which performance in dual tasks was compared with that in single tasks, revealed that participants had a…

Purpose: To describe cochlear implant users' phoneme labeling, discrimination, and prototypes for a vowel and a sibilant contrast, and to assess the effects of 1 year's experience with prosthetic hearing. Method: Based on naturally produced clear examples of "boot," "beet," "said," and "shed" by 1 male and 1 female speaker, continua with 13…

Olfactory memory is especially persistent. The current study explored whether this applies to a form of perceptual learning, in which experience of an odor mixture results in greater judged similarity between its elements. Experiment 1A contrasted 2 forms of interference procedure, "compound" (mixture AW, followed by presentation of new mixtures…

An exercise based on images that might shift the balance in favor of students who have superior visual perception and possibly those with language problems and specific learning disabilities, was reviewed. The pictorial format of learning exercise not only increased the students' performance, but also helped students with specific learning…

We explore in this study how infants may derive phonetic categories from adult input that are highly variable. Neural networks in the form of self-organizing maps (SOMs; Kohonen, 1989, 1995) were used to simulate unsupervised learning of Mandarin tones. In Simulation 1, we trained the SOMs with syllable-sized continuous F[subscript 0] contours,…

A LITERATURE REVIEW OF SIX KEY CONCEPTS OF PSYCHOLINGUISTIC PROCESSES IS PRESENTED. THE SIX CONCEPTS ARE (1) COGNITIVE GROWTH, (2) PSYCHOLINGUISTIC MODELS SUCH AS THE ILLINOIS TEST OF PSYCHOLINGUISTIC ABILITIES (ITPA), (3) INTERSENSORY INTEGRATION, (4) REMEDIAL TEACHING TECHNIQUES, (5) VISUALIZATION IN INTEGRATIVE TASKS, AND (6) CONCEPTUAL SCHEMA.…

This study examines the educational persistence of women of African descent (WOAD) in pursuit of a doctorate degree at universities in the southeastern United States. WOAD are women of African ancestry born outside the African continent. These women are heirs to an inner dogged determination and spirit to survive despite all odds (Pulliam, 2003,…

This dissertation compares the phonetic and phonological features of adult non-speakers' productions of words in an endangered Native American language, Oregon Northern Paiute (also known, and hereafter referred to, as Numu), to productions by fluent speakers. The purpose of this comparison is two-fold. The first purpose is to examine the…

This study endeavored to determine (1) the reliability with which selected individual tests of language, visual and auditory perception, and auditory-visual perceptual integration can be administered through group testing; (2) the decrease in administration and scoring time by using these instruments in a group manner, and (3) the relationships…

An effective way to teach the concept of image is to give students a model of human vision which incorporates a simple mechanism of depth perception. In this study two almost identical versions of a curriculum in geometrical optics were created. One used a mechanistic, interpretive eye model, and in the other the eye was modeled as a passive,…

Instructional design is a process that is creative, active, iterative and complex; however, many diagrams of instructional design are interpreted as stifling, passive, lock-step and simple because of the visual elements used to model the process. The purpose of this study was to determine the expressed perceptions of the types of flow diagrams…

To test the stability of role perception, multidimensional scaling analyses were applied to family role constructs (Mother, Father, etc.) based on data from two methods which differed significantly in terms of the types of judgements of stimulus dissimilarity which were required. (Author)

An experimental test battery designed to measure several perceptual abilities was administered to 1,368 (51.8% male) paying clients of the Johnson O'Connor Research Foundation (JOCRF) in an effort to identify and measure three perceptual abilities: (1) flexibility of closure; (2) speed of closure; and (3) spatial scanning. Subjects, who ranged in…

Behaviorism cannot adequately explain language processing. A synthesis of the psycholinguistic and information processing approaches of cognitive psychology, however, can provide the basis for a speculative analysis of reading, if this synthesis is tempered by a perceptual learning theory of uncertainty reduction. Theorists of information…

The sentence processing abilities of a conduction aphasic adult woman with a documented phonological coding deficit were investigated in tests of auditory and visual sentence comprehension of reversible active and passive sentences and spatial prepositions, sentence production through story completion and picture description, and repetition of…
