Phonological fusion occurs when the phonemes of two different speech stimuli are combined into a new percept that is longer and linguistically more complex than either of the two inputs. The present article is an investigation of the conditions necessary and sufficient for fusion to occur. (Editor/RK)

Research is reported which examined the effect of various factors on the frequency of phonological responses. Phonemic order and location of clusters within a syllable affected fusion. Initial stop-liquid clusters fused readily; final liquid-stop clusters rarely fused. Some subjects fused on most or all trials; others fused less frequently.…

Definitions and specific breakdowns of four (auditory reception, visual sequential memory, verbal expression, and auditory closure) of the 12 language areas of the new Illinois Test of Psycholinguistic Abilities (ITPA) are presented. Auditory reception is defined as the ability to understand the meaning of materials or stimuli that are heard and…

Two experiments are reported in which cardiac habituation and dishabituation to pure tone stimuli were studied in well and malnourished Guatemalan infants. In both studies the magnitude of the orienting response was found to be attenuated or completely absent in infants suffering from nutritional insult. The findings were taken as evidence of a…

To measure the symmetry of adult categorical phoneme perception, 10 adult male undergraduate students enrolled in an introductory psychology class were the subjects for this study as part of their course requirements. The stimuli used in this study were prepared at Haskins Laboratories by means of a parallel resonance synthesizer and computer. The…

Designed to aid in developing auditory perception, this manual provides a program of remediation for children at the fourth through sixth-grade level. The book is divided into two sections. The first consists of seventy-five essays, each written at three levels of difficulty. The level most appropriate for the student is determined and is used for…

The items in this annotated bibliography include studies, journal literature, USOE-sponsored research, and the conference proceedings of the International Reading Association, covering the years 1950 to 1969. Part I is devoted to "Audition" which encompasses reports based on all aspects of listening and its relationship to reading, and "Auditory…

Retention of verbal material presented in a normal linear manner was compared to retention of the same material presented in simultaneous messages for this study. The subjects were 180 undergraduates, and each was randomly assigned to one of the nine experimental groups formed by combinations of presentation--linear, two simultaneous messages, or…

EFFECTS OF TONAL MEMORY OF TWO KINDS OF FACTORS WERE STUDIED. THE FACTORS WERE (1) THE CHARACTERISTICS OF STIMULI PRESENTED TO THE SUBJECT IN A PITCH IDENTIFICATION TASK, AND (2) THOSE EFFECTING THE RESPONSE THAT THE SUBJECT MAKES IN SUCH A TASK. FIVE HYPOTHESES WERE ADVANCED FOR STUDY. THE UNDERLYING ASSUMPTION WAS THAT THERE ARE IMPORTANT…

Describes two experiments which examined the relation between neonatal cry features and obstetric histories. Experiment 1 showed differences in pitch and durational features between the cries of high- and low-complication newborns. Experiment 2 showed differences in the cry ratings of the two groups on dimensions such as aversive, sick, urgent,…

Outlines two competing hypotheses concerning the nature of inter-modal sensory development. Research on auditory-visual coordination in young human infants is reviewed. It is concluded that the data support the notion of ontogenetic development being a process of intergration between sensory systems that are initially relatively independent.…

Attempts to account for many of the differences between vowels and consonants and between speech and nonspeech, in terms of the range of the contexts in which they are set. Explanations of the different overall levels of discriminability in vowels and consonants in various tasks in terms of their "encodedness" are replaced by a general model…

Examines the auditory evoked potentials (AEP) in the left and right hemispheres of the brain in response to variations in voice onset time (VOT) differences within and between phoneme categories. Subjects were 12 preschool children. (BD)
