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.     

A comparison of same- and cross-age interactions in mixed-age groups

This study investigated the types of interactions occurring within and between age groups in mixed-age preschool classes. Using point-time sampling procedures, the peer interactions of 30 3- to 5-year-old preschool children enrolled in two preschool classes were recorded. Interactions were coded according to six categories and according to the role of the target child in the interaction. Contrary to popular assumptions about interactions in mixed-age groups, results indicated that for both the older and younger children the types of interactions occurring across age groups did not differ significantly from interactions within same-age groups. Symmetrical rather than asymmetrical relationships across age groups were found in the exchange of nurturance, direction and information.     

Personality and spirituality: comparative TATs of high-achieving Rajneeshees

The Thematic Apperception Test (TAT) was administered to followers of Bhagwan Shree Rajneesh in their commune in central Oregon. The Rajneeshee subjects had been high achievers (with advanced degrees and/or previous incomes greater than 30,000 dollars in 1984 dollars). Later, TATs were administered to persons matched for gender, age, education, and occupation but not involved in new religions. The final matched sample included 24 men and 20 women, half of whom were Rajneeshees. TATs were coded for a variety of formal variables as well as personality ratings. Though the analysis showed no between-group differences on most variables, significant mean differences occurred on ratings of unusual conditions, quest, and narcissism, with Rajneeshees higher than comparison subjects. Gender differences in personality variables were not conspicuous. Factor analysis established a strong productivity element. Card 16 (the blank card) provided the greatest number of differences.     

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.     

Cortical alpha rhythm, biofeedback, and the determinants of subjective state

A critical assumption in the rationale for the clinical application of voluntary control over central nervous system (CNS) activity is that there exists a direct relationship between specific CNS activities and specific subjective mood states. The experiment reported here was based on the idea that a joint manipulation of both cognitive and physiological (i.e., alpha electroencephalographic [EEG]) variables would provide information required for an explication of the processes involved in subjective mood change. Three main variables were considered in the present experiment. First, the instructions were designed to induce a "set" or expectations for either positive or negative changes in subjective mood. Second, the type of feedback (alpha or not alpha) was varied. Those in the not-alpha feedback condition received feedback contingent on the absence of alpha activity, whereas those in the alpha feedback condition received feedback contingent on the presence of alpha activity. Third, an estimate of each individual's baseline alpha density was obtained, and on this basis subjects were classified as high-baseline or low-baseline subjects. Baseline alpha density, alpha density during training, and subjective mood were all considered as continuous variables. The results of the present study indicate that biofeedback of the cortical alpha rhythm is neither a sufficient nor a necessary condition for changes in subjective mood. In addition, the type of instructions designed to set subjects for positive or negative alterations in subjective states is predictive of changes in subjective state reported during alpha biofeedback training as well as of success at controlling and changing EEG during feedback training. The data presented here permit a direct examination of the actual relationship of EEG changes to changes in subjective mood state. Similar shifts in subjective mood state can be obtained with either increases or decreases in alpha activity. Further, both positive and negative subjective experiences can be associated with increases in alpha activity.

Discourse functions of thematization and topicalization

Thematization, the relative frequency of a discourse referent, and topicalization are conceptualized as related discourse functions. In a probe recall experiment, a word with a thematized referent was a better recall probe than a word with a nonthematized referent. Also, an agent noun was a better prompt than a recipient, and this semantic variable interacted with topicalization such that a semantic recipient was a better prompt when it was topic than when it was comment. In a second experiment, subjects' choice between semantically equivalent active and passive sentences was influenced by thematization. Thematized nouns were chosen as topics more often than nonthematized nouns, and nouns used as paragraph titles were chosen as topics slightly more than nontitle nouns. It is suggested that twin discourse functions are served by thematization and topicalization, the former providing stable referential focus and the latter providing momentary referential focus.     

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.
