How (Fast) Can I Help You? Tone of Voice and Telephone Operator Efficiency in Interactions1

This study examined how tone of voice related to directory assistance operators' s]peed at handling customer calls. Brief (5-s) audio exerpts of telephone operator conversation were presented to judges who rated these on 5 personality dimensions and 5 vocal qualities. When these measures were correlated with a key measure of job performance, namely call duration, results showed that operators who were faster at handling calls were rated as significantly more enthusiastic, sympathetic, confident, professional, and friendly (average r= -.56). The voices of faster operators were also rated as significantly more changing (vs. monotonous) and as containing clearer (vs. slurred) pronunciation. Results are discussed in terms of the role that tone of voice plays in telephone operator-customer interaction, and telephone interactions more generally.     

Perceptual averaging by eye and ear: Computing summary statistics from multimodal stimuli

Beyond perceiving the features of individual objects, we also have the intriguing ability to efficiently perceive average values of collections of objects across various dimensions. Over what features can perceptual averaging occur? Work to date has been limited to visual properties, but perceptual experience is intrinsically multimodal. In an initial exploration of how this process operates in multimodal environments, we explored statistical summarizing in audition (averaging pitch from a sequence of tones) and vision (averaging size from a sequence of discs), and their interaction. We observed two primary results. First, not only was auditory averaging robust, but if anything, it was more accurate than visual averaging in the present study. Second, when uncorrelated visual and auditory information were simultaneously present, observers showed little cost for averaging in either modality when they did not know until the end of each trial which average they had to report. These results illustrate that perceptual averaging can span different sensory modalities, and they also illustrate how vision and audition can both cooperate and compete for resources.

Asymmetrical effects of Pavlovian excitatory and inhibitory aversive transfer on Pavlovian appetitive responding and acquisition

Predictions of a theory of Pavlovian motivational transfer, which incorporates principles of both the theory of reciprocal inhibition and the Rescorla-Wagner model, were tested in several Pavlovian aversive to Pavlovian appetitive transfer tasks. As predicted, the presence of a signal for an aversive event, conditioned stimulus (AV CS+), reliably suppressed performance of appetitive conditioned responses (CRs) whether imposed during acquisition or on independently established responding. Acquisition of appetitive responding to a novel CS reinforced in compound with an AV CS+, however, was enhanced (“superconditioning”). This observation suggests that the effects of a discrepancy between expectation and actual outcome on a conditioning trial are influenced by the affective value of both the expectation and the reinforcer. These transfer effects were not symmetrical for an inhibitory aversive stimulus (AV CS?). An AV CS? did not enhance appetitive responding compared to a random control condition, nor did the AV CS? reduce (i.e., block) appetitive conditioning to a novel CS when appetitive reinforcement occurred in the presence of the AV CS?. Comparison of the two shock-exposed conditions with a naive control condition suggests that previous results that were apparently consistent with inhibitory aversive enhancement and blocking of appetitive conditioning may have been due to aversive context conditioning.     

WIEMAN'S MISUNDERSTANDING OF DEWEY: THE CHRISTIAN CENTURY DISCUSSION

Abstract. An important issue in the development of the American school of philosophy known as critical naturalism was whether the naturalistic vision implied a humanistic or a theistic interpretation of religion. Is the divine a creativity within nature but more than human effort, or is it the human vision of ideal possibilities and the effort to realize them? This issue is clarified through a study of the concept of the divine developed by the leading naturalist John Dewey in A Common Faith, the misunderstanding of this book by Henry Nelson Wieman, and the discussion of this misunderstanding in the pages of Christian Century. The essay concludes that Wieman's misunderstanding of Dewey is instructive in that it reveals unintended possibilities in Dewey's thought.     

Experience and desire: A new format for Sensation Seeking Scales

A new form (VI) of the Sensation Seeking Scale (SSS) was developed which separates reports of past experiences from desired or intended future experiences on both Disinhibition (Dis) and Thrill and Adventure Seeking (TAS) factors. Factor analyses were used to select items for the scales. High internal reliabilities were found for the Experience-Dis, Intention-TAS, and Intention-Dis scales, but only moderate reliability was found for the Experience-TAS scale. Retest reliabilities were high for all scales. The Experience-TAS and -Dis scales were highly correlated for males but not for females. The Experience- and Intention-TAS scales were moderately correlated, and the Experience- and Intention-Dis scales were highly correlated for both sexes. Both the TAS and the Dis scales on form V were highly correlated with the corresponding Intention scales on form VI. Uses for the new SS scales in individual assessment are suggested.A copy of SSS form VI may be obtained from the author.
