Judgments of communicative intent in conversation

In conversation people make specific statements that are intended to accomplish some particular social action (e.g., to praise, criticize or sympathize). To communicate effectively, people must consensually perceive the intentions of each other’s messages. In this research we examined the degree of consensus in judgments of communicative intent. Participants engaged in separate, brief conversations with three friends, watched videotapes of their interactions, and judged the communicative intent of 6 randomly selected statements. Observers also judged these statements under one of three conditions: audio-visual, audio, or text. Analyses showed that participants agreed strongly in their judgments of intent and that observers also agreed in their judgments, but not as much as participants.

A Case that the Field of Psychotherapy Is Closed-Minded to Revolutionary New Ideas

The case is that, with regard to revolutionary new ideas, the field of psychotherapy (a) has a glaring absence of indicators of open-mindedness; (b) is distinctly and conspicuously closed-minded; (c) this closed-mindedness is extreme, and differentiates the field from many other fields; and (d) the field is essentially barricaded against knowing that it is so conspicuously closed-minded. The fanciful and unrealistic revolution would be for the field to become open-minded. Invitations are extended to any psychotherapists with a spark of open-minded possibilities.     

What Revolution Would You Like to See In the Field of Psychotherapy? Introduction

Contributors to a theme issue were invited to address two questions: (a) What revolution would you like to see in the field of psychotherapy? (b) What makes it revolutionary? That is, how and why is it revolutionary? In a spirit of helping contributors do their job, an attempt is made to clarify the meaning of a revolutionary new idea in the field of psychotherapy by identifying components that do not especially belong, and by proposing components that can be thought of as defining the proposed meaning.

ON THE IMMEDIACY OF PHONETIC PERCEPTION

Abstract— If, as we believe, language is a specialization alt the way down to its roots, then perception of its consonantal elements should be immediately phonetic, not as in the conventional view, a secondary translation from percepts of an auditory sort. Supporting observations come from an experiment in which formant transitions that distinguish [da] and [gal were presented as sinusoids and combined with a synthetic syllable made of resonances, thus causing the auditory system to treat these acoustically incoherent parts as different sources Evidence for the source difference was varied by changing the intensity of the sinusoids relative to the remainder of the syllable. Over the greater part of a 60-dB range, listeners accurately identified the consonants, indicating that they had integrated the stimuli according to a coherence that existed only in the phonetic domain. At the lowest intensities, indeed, the consonants were accurately identified, even though the whistles—the normal responses to the sinusoids—were not. There followed then a range over which perception was duplex. Both consonants and whistles were accurately identified At the highest intensities, phonetic integration failed, but accurate perception of the whistles was maintained. That the phonetic percept was present when as auditory counterpart was absent, and vice versa, is evidence that the phonetic percept is independent of its auditory counterpart and not a translation from it, as is the fact that the two percepts followed very different courses in response to the experimental variable.     

Luria-nebraska neuropsychological battery: High rates of false positives for geriatirc subjects

This study examined false positive rates obtained for two normal adult age groups, using three different methods for interpreting performances on the Luria-Nebraska Neuropsychological Battery (LNNB). Among normal subjects ages 18 to 30 and ages 65 to 85, false positive rates were found to range from 3.9% to 7.7% for younger subjects and 13.5% to 32.7% for older subjects. Significant differences were found between the proportion of false positives in each age group on each method of interpretation. A lack of agreement was found between the three different methods of interpretation concerningwhich subjects should be classified as impaired. Further analysis was performed by dividing older subjects into two groups, ages 65 to 70 and over 70. False positive rates for subjects over age 70 were found to range from 20.7% to 41.4%. Significant differences were also found between the proportion of false positives in each of these two groups.

An effect of linguistic experience: The discrimination of [r] and [l] by native speakers of Japanese and English

To test the effect of linguistic experience on the perception of a cue that is known to be effective in distinguishing between [r] and [l] in English, 21 Japanese and 39 American adults were tested on discrimination of a set of synthetic speech-like stimuli. The 13 “speech” stimuli in this set varied in the initial stationary frequency of the third formant (F3) and its subsequent transition into the vowel over a range sufficient to produce the perception of [r a] and [l a] for American subjects and to produce [r a] (which is not in phonemic contrast to [l a ]) for Japanese subjects. Discrimination tests of a comparable set of stimuli consisting of the isolated F3 components provided a “nonspeech” control. For Americans, the discrimination of the speech stimuli was nearly categorical, i.e., comparison pairs which were identified as different phonemes were discriminated with high accuracy, while pairs which were identified as the same phoneme were discriminated relatively poorly. In comparison, discrimination of speech stimuli by Japanese subjects was only slightly better than chance for all comparison pairs. Performance on nonspeech stimuli, however, was virtually identical for Japanese and American subjects; both groups showed highly accurate discrimination of all comparison pairs. These results suggest that the effect of linguistic experience is specific to perception in the “speech mode.”     

Bargaining ability,the utility of playing a game,and models of coalition formation

A utility function for playing a given position in a game is developed as a natural extension of the utility function which defines the rewards available in the game. This function is determined by a player's opinion of his bargaining ability. A characterization of such utilities is obtained which generalizes previous results that the Shapley value and Banzhaf-Coleman index are both cardinal utility functions which reflect different bargaining abilities. The approach taken here is related to models of coalition formation.
