Spectral cues provided by the pinna for monaural localization in the horizontal plane

Six subjects located, monaurally, 1.0-kHz-wide noise bursts whose source originated on the side of the functioning ear and whose center frequency ranged from 4.0 through 9.0 kHz (Part 1). Irrespective of their actual locations, the stimuli appeared to migrate from the frontal sector of the arc toward the side as the center frequency was increased above 4.0 kHz. For some subjects, the sounds appeared again in front at the higher center frequencies. Comparable data were obtained with noise bursts 2.0 kHz in width. We referred to these constellations of location judgments, influenced by the frequency composition of the stimuli, as spatial referent maps. In Part 2, we measured, by means of a miniature microphone placed at the entrance of the external ear canal, the pinna amplification function for these same stimuli emanating from the same locations. The results showed a positive relation between the apparent location of noise bursts centered at 6.0 kHz and above and the relative amplification provided by the pinna. Localization performances by two subjects, chosen on the basis of their noncorresponding spatial referent maps, were examined for stimuli of wider bandwidths IPart 3). Their proficiency differed markedly from one another, which we accounted for in terms of different spatial referent maps that were associated with differences in the pinna amplification function.     

Analyzing mothers' speech to young autistic children: A methodological study

The development of a technique for analyzing mothers' speech to young children is described. The need for such a measure arose from two linked studies of autistic children, one comparing them with developmental dysphasic children and the other evaluating the results of a home-based approach to treatment. A 17-category system was developed which could encompass almost all the types of speech shown by mothers of young autistic and normal children and which differentiated between the speech used by different mothers in a way that was meaningfully related to the child's level of language development. The categories proved to be easily applicable and to show good inter-observer reliability. Tape-recordings made during home observations were found to be the best source of speech samples. The problems of time sampling, length and nature of speech sample, and observer effects are discussed.We are most grateful to our colleagues Dr. Lionel Hersov and Mr. William Yule for many helpful suggestions in developing the measures and for their comments on an earlier draft of the paper. The study is supported by a grant from the (British) Department of Health and Social Security.     

Semantic processing in dichotic listening? A replication

This experiment explores semantic processing of one message while another is attended to and shadowed. It was an attempt to replicate and clarify an earlier finding by Lewis (1970). Like Lewis, we found that mean shadowing latency was increased when a synonym of the shadowed word coincided with it on the unattended channel. However, this occurred only with synonyms in an early list position and appeared to affect only a small proportion of trials. The implications of this and other recent findings for theories of selective listening are discussed.     

Listening to speech at two levels at once

Monitoring performance was compared when subjects were asked to listen simultaneously for two different targets embedded in a sentence and when they listened only for one. The effects of different combinations of targets (phonemes, words, or meanings) were investigated and an attempt was made to separate the effects of particular combinations from the effects of difficulty of the two component targets. Performance was worse when either of two targets might occur than when subjects knew which single type to listen for. However there were no differences attributable to which particular types of targets were being combined. Listening for a phonemic target was as difficult to combine with listening for a semantic target as for another phonemic target. The result is consistent with a central speech analysing system whose limited processing capacity must be shared (at least in this monitoring task) both between and within all relevant levels of linguistic analysis, rather than with relatively independent subsystems for each type of listening.     

A relational recasting of the principles of emotional competence

ABSTRACT

Carolyn Saarni’s theory of emotional competence has made a central contribution by directing attention to some important functions of emotion in social interaction. Her work is permeated with examples of how emotions function within both successful and unsuccessful social interactions and relationships. An examination of her stated principles of emotional competence suggest in places a perspective that is primarily intrapsychic in nature, harking back to the early roots of emotion theory and research. In this piece, we note where Saarni has advanced implications of a relational theory of emotion for understanding emotional competence. In addition, we reframe some of Saarni’s principles to make them more consistent with current relational approaches to emotion. Finally, we offer additions and extensions that we believe are compatible with the general direction of her thinking before her untimely death.     

Defense mechanisms and self-reported violence toward partners and strangers

We examined the relationship between defense mechanisms and self-reported violence toward partners and toward strangers in a sample of college student men. Fifty men completed the Thematic Apperception Test (TAT; Murray, 1943) and the Conflict Tactics Scale (CTS; Straus, 1979), a self-report measure of strategies (including violence) for resolving conflicts with partners and strangers. The TAT responses were coded for defense mechanisms with the Defense Mechanisms Manual (Cramer, 1991b). The relative use of identification was negatively correlated (r = -.49, p <.001), and the relative use of projection was positively correlated (r =.49, p <.001) with the most extreme CTS report of violence toward partners. The relative use of identification was negatively correlated with the most extreme CTS report of violence toward strangers (r = -.34, p <.05). The relative use of denial was positively correlated with the most extreme CTS report of violence toward strangers (r =.32, p <.05).
