Bogus physiological feedback and response thresholds of Repressers and Sensitizers

Repressers and Sensitizers viewed tachistoscopically presented TAT transparencies under conditions of high and low bogus physiological feedback. As predicted, during high bogus physiological feedback, Repressers showed a significant increase and Sensitizers showed a significant decrease in response thresholds. These results serve to extend the validity of bogus physiological feedback procedures in the analog investigation of emotion and offer theoretical implications relevant to the areas of personality, emotion, psychophysiology, and psychopathology.     

Spelling dyslexia: A form of cross-cuing

A patient with spelling dyslexia maintained the ability to write, spell, and pronounce spelled nonsense words and words that require knowledge of orthographic rules of language. He was unable to perform grapheme-phoneme conversions except after naming the letter involved. We propose that he uses a letter-naming strategy to circumvent the disconnection of visual areas from the area of visual word images and that his letter-naming strategy represents a compensatory cross-cuing strategy.     

Event-related potential studies of cerebral specialization during reading: I. Studies of normal adults

A number of methodological features were incorporated in a paradigm designed to maximize the likelihood of finding reliable event-related potential (ERP) signs of functional specializations between and within the cerebral hemispheres. Every subject was more accurate in identifying words presented to the right than to the left visual field. The morphology of the ERPs elicited by these words varied considerably as a function of electrode position both within and between the hemispheres. Amplitude asymmetries of ERP components recorded from occipital regions of the two hemispheres varied systematically with the position of the word in the visual field. On the other hand, ERPs from more anterior (temporal and frontal) regions displayed large asymmetries which were in the same direction regardless of the visual field of word presentation. The most prominent such asymmetry was in the negativity in the region 300–500 msec (N410) which was larger in the left than the right hemisphere in every subject. These results demonstrate that in this paradigm which demands specialized language processing ERPs are sensitive to aspects of cerebral organization both within and between the two hemispheres.     

Memory scanning of shapes,colors, and compounds: A comparison of retarded and nonretarded adults

Three experiments were performed to assess memory scanning of shapes, colors, and shape-color compounds by retarded and nonretarded people. Attributes comprising compounds provided either redundant or nonredundant information. Large retarded-nonretarded differences in reaction time were obtained. In contrast to previous reports of slow scanning of digits and nonsense shapes by retarded people, scan rates for shapes and colors did not differ between groups. Retarded subjects were not characterized by a deficient scan rate. Although compound stimuli required twice as many attributes in their repersentation as did simple stimuli, they were not scanned more slowly, indicating that per item scan rate is not determined by the number of attributes required to define each item. Both groups were able to exploit redundant relevant information to achieve faster processing than in simple conditions. Decision rules for rejecting compound stimuli comprised one, two, or more binary tests. Groups did not differ in speed of performing elementary binary test(s).     

The role of distinctive features in the dichotic perception of vowels

A dichotic listening experiment was conducted to determine if vowel perception is based on phonetic feature extraction as is consonant perception. Twenty normal right-handed subjects were given dichotic CV syllables contrasting in final vowels. It was found that, unlike consonants, the perception of dichotic vowels was not significantly lateralized, that the dichotic perception of vowels was not significantly enhanced by the number of phonetic features shared, and that the occurrence of double-blend errors was not greater than chance. However, there was strong evidence for the use of phonetic features at the level of response organization. It is suggested that the differences between vowel and consonant perception reflect the differential availability of the underlying acoustic information from auditory store, rather than differences in processing mechanisms.     

A theory of careers encounters sex: Reply to Holland (1976)

This paper is the third in a series beginning with a report (by the authors) of research on the application of Holland's theory of careers to women and men. Holland's response, “The Virtues of the SDS …” is considered, in particular, research he cites on the effect of the Self-Directed Search (SDS) on counselees and his advocacy of raw score reports of personality patterns. The widely divergent career options suggested to men and women by SDS raw scores are noted and misunderstandings concerning the implications of Holland's assessment procedures for his theory are discussed. Holland's defense of raw score reports of personality characteristics is found wanting, especially in light of the support provided for his theory by normed scores.     

Validity of sex-balanced interest inventory scales

The purpose of this study was to examine the relative effectiveness of sex-balanced and sex-restrictive raw score interest scales in discriminating among vocational preference groups. Analyses were conducted separately for 502 males in six vocational preference groups and 878 females in five vocational preference groups. The degree and nature of the discrimination among groups were highly similar for the two types of scales for both males and females. Centour scores derived from sex-balanced and sex-restrictive raw scores resulted in essentially the same percentages of correct classifications of group membership. The results of this study suggest that the large sex differences traditionally found in interest inventory items may not be a necessary concomitant of validity. Hence, interest inventory reports that reflect these differences may unnecessarily restrict the career suggestions they provide to women and men.     

Clinician attitudes toward stuttering in the United States and Great Britain: A cross-cultural study

The attitudes toward stutterers and stuttering of 702 speech-language clinicians in the United States and Great Britain were studied. Three hundred seventy-one clinicians from six states in the U.S. and 331 clinicians from England and Wales completed the Clinician Attitudes Toward Stuttering (CATS) Inventory. Results of the study were analyzed in terms of differences and similarities in attitudes between the two groups with respect to the etiology of stuttering, early intervention, the effectiveness of stuttering therapies, various therapy techniques, stutterers and their personality, parents of stutterers, clinicians, and reactions of others to stutterers.     

Forgetting in retarded and nonretarded persons under conditions of minimal strategy use

Short-term memory processes of mentally retarded (mild, moderate, and severe) and nonretarded persons were compared in a delayed matching-to-sample task that minimized the use of verbal rehearsal. In addition to trials with delays up to 20 s, the inclusion of trials on which the sample and comparison stimuli occurred simultaneously made it possible to isolate memory and discriminability. Forgetting was most pronounced between the simultaneous and 0-s conditions, and nonretarded subjects forgot less than retarded subjects between these conditions. There were no group differences beyond the 0-s delay. Ease of strategy use failed to account for individual differences, and reported strategy use was not related systematically to performance. These findings are incompatible with the hypothesis that normal-retarded differences occur only on tasks involving effortful cognitive strategies. Differences between nonretarded and retarded groups in this study may be due to a failure in automatic encoding processes in retarded persons.     

The miscommunication of deception: An adaptive perspective

Undergraduates were videotaped as they told lies and truths about their last job. Later, these undergraduates viewed the videotape and tried to guess which of their fellow subject were lying. Monetary incentives had been offered for successful lying and lie detection. Our subjects showed a “demeanor bias”—some looked honest even when they were lying; others looked dishonest even when they were telling the truth. These differences in apparent honesty were the primary determinant of deception judgments; perceivers' detection skills played a lesser role. Honest-looking subjects were predisposed to perceive others as dishonest. In general, our liars used hand gestures, maintained eye contact, and refrained from smiling. Perceivers misconstrued these behaviors as signs of honesty and could not often detect deceit—unless the lie was being told by a subject who had earlier told the truth. We draw on sociobiological concepts and offer an adaptive perspective on human deceit.
