A word-finding computer program with a dynamic lexical-semantic memory for patients with anomia using an intelligent speech prosthesis

A computer program for a portable microprocessor has been developed which aids anomic patients in finding words given clues about the target word. Over time the lexical-semantic memory is reorganized automatically depending on the frequency of word usage by an individual patient. Words can be added or deleted to fit the patient's idiosyncratic lexicon. A clinical example is given. The program is being tested with a variety of aphasic-anomic patients with major word-finding difficulties.     

Phonological encoding and ideographic reading by the disconnected right hemisphere: Two case studies

The mute disconnected right hemispheres (RHs) of two commissurotomy patients are able to understand spoken words and read printed words by matching them with pictures of the objects named. In this paper we report the results of five experiments. The RH of one patient could “evoke the sound image” of a word to the extent of matching two pictures with homonymous names (experiment 1) or with rhyming names (experiment 2) without being able to name either one. This transformation of picture to covert sound does not depend on orthographic similarity of word ends as a clue to homonymy or rhyme, nor does it improve with short-term learning. Yet neither RH can translate print into sound by matching a spelled word with a picture that has a rhyming name (experiment 3) or by matching two orthographically dissimilar rhymes, be they meaningful (experiment 4) or nonsense words (experiment 5). We suggest that these RHs read “ideographically,” recognizing words directly as visual gestalts without intermediate phonetic recoding or grapheme-to-phoneme translation.     

Sex differences in attribution for occupational success

A study was conducted to both test and extend Deaux's (Sex: A perspective on the attribution process. In J. H. Harvey, W. J. Ickes, & R. F. Kidd, (Eds.), New directions in attribution research, Volume 1. Hillsdale, N.J.: Erlbaum, 1976) expectancy model of sex-linked differences in attribution for success. Specifically, it was hypothesized that female occupational subjects would attribute success more to the unstable causes of effort and luck, as well as the stable internal cause of interpersonal skill, while male occupational subjects would make higher attributions to the stable causes of ability and task ease. This hypothesis was supported for the causes of effort, luck, and task ease. Additionally, a comparison between sex differences in attribution occurring within a nonpersonal vs. personal frame of reference showed three of the expected sex differences in attribution to be stronger in the latter condition. Moreover, it was shown that this difference was largely accounted for by changes in females' rather than males' attributions. A final hypothesis, namely, that males would perceive themselves as more successful in their occupations than females, was not confirmed.     

Social motives among Anglo American and Mexican American children: Experimental and projective measures

The measurement approaches to social motives, cooperation-competition games and projective tests, have revealed apparently similar findings: Anglo American children are more competitive and higher in n Achievement compared to Mexican American children, who are more cooperative and higher in n Affiliation. The present experiment tested the extent to which (1) competitiveness is related to n Achievement, (2) cooperativeness is related to n Affiliation, and (3) the cultural differences in cooperation-competition are related to those in n Affiliation and n Achievement. Results indicate that social motives inferred from a cooperation-competition game have a meaningful relation to those inferred from a projective test, but that the cultural differences in cooperation-competition are larger and are not explained by cultural differences in n Affiliation and n Achievement. Social motives inferred from each measurement methodology, while somewhat related, are distinct.     

Desiring and expecting to work among high school girls: Some determinants and consequences

The effects of mother's and father's work status and of social-psychological intervening variables on high school girls' orientation to the labor force are examined. The dependent variables are separate indicators of whether the girls want and whether they expect to have an occupation. In these data from 1965, a log linear analysis shows that whether the mother worked was the major background influence on the dependent variables; father's occupation had no significant independent effect. In addition, two “ideological” variables, the girl's identification with the mother and beliefs in individual achievement, strongly influenced the dependent variables, in a way that did not merely mediate the background effects. Finally, some consequences of wanting and/or expecting to work are examined, and it is argued that the choice of career pattern (housewife versus paid employment) was a central one in girls' attitudinal structures.     

Male alcoholics,secondary psychopathy and Eysenck's theory of personality

The scores of several samples of male alcoholics and others on the MAC Scale (an MMPI-derived scale for the differentiation of male alcohol abusers from non-substance-abusing male psychiatric outpatients) are summarized, and the responses of the false negatives and false positives from the scale's standardization samples are analyzed. The following 7conclusions were reached: (1) There are two broad classes of male alcoholics—those who fall into the E + N + quadrant of secondary psychopathy and those who fall into the E - N + quadrant of neurotic introversion; (2) Unselected runs of male alcoholics populate these two quadrants in a quite stable ratio of 17 to 3, respectively; (3) Pari passu, Eysenck's placement of alcoholics in the E + N + quadrant will be upheld in approximately 85% of the cases while those who hold that alcoholics are ‘dysthymics who also drink too much’ will find themselves in error in approximately similar degree.     

Interpreting social-sexual behavior in a work setting

The influx of women into the work force, especially into nontraditional jobs, has facilitated interest in the topic of sexual harassment and, more generally, sexuality at work. Survey research data show disagreement about the interpretation of interactions between the sexes at work. This study was designed to learn more about the way people interpret ambiguous, but potentially sexual, interactions between the sexes in a work setting. Respondents were asked to evaluate a vignette depicting such an interaction. The vignettes were composed so that three dimensions were manipulated: the sex of the initiator of the behavior, the status of the initiator relative to the target, and the type of behavior. These manipulated dimensions, along with the sex of the respondent, were used as variables to examine the respondent's interpretation of the vignettes. Four-way ANOVAs showed that the independent variables were related to the evaluation of the relationship between the initiator and the target, the evaluation of the behavior, the appropriateness of the behavior, and the likelihood of the behavior. Men interpreted the vignettes more positively than did women. Incidents initiated by women were viewed more positively. Those initiated by persons with higher status than the target were seen less positively. Respondents, especially women, considered incidents that included touching to be negative. This was especially so when the touching was combined with a comment on work, and this effect was exacerbated when the behavior was initiated by a male and/or higher status person.

The voice problems of stutterers: A practical approach from clinical experience

Voice disorders, which may be caused by the stuttering problem, have been noted in at least one-third of stutterers seen. Basically, stutterers have false speech images that normal speech is perfect and without natural dysfluencies (repetitions, pauses, etc.). Many stutterers also have erroneous vocal images of how they should or should not sound. Both images control speech and voice. Clinical experience indicates that vocal rehabilitation should be used in conjunction with speech therapy for many stutterers.     

Cerebral asymmetry for American Sign Language: The effects of moving stimuli

Previous studies of cerebral asymmetry for the perception of American Sign Language (ASL) have used only static representations of signs; in this study we present moving signs. Congenitally deaf, native ASL signers identified moving signs, static representations of signs, and English words. The stimuli were presented rapidly by motion picture to each visual hemifield. Normally hearing English speakers also identified the English words. Consistent with previous findings, both the deaf and the hearing subjects showed a left-hemisphere advantage to the English words; likewise, the deaf subjects showed a right hemisphere advantage to the statically presented signs. With the moving signs, the deaf showed no lateral asymmetry. The shift from right dominance to a more balanced hemispheric involvement with the change from static to moving signs is consistent with Kimura's position that the left hemisphere predominates in the analysis of skilled motor sequencing (Kimura 1976). The results also indicate that ASL may be more bilaterally represented than is English and that the spatial component of language stimuli can greatly influence lateral asymmetries.
