The role of second formant transitions in the stop-semivowel distinction

An experiment was conducted which assessed the relative contributions of three acoustic cues to the distinction between stop consonant and semivowel in syllable initial position. Subjects identified three series of syllables which varied perceptually from [ba] to [wa]. The stimuli differed only in the extent, duration, and rate of the second formant transition. In each series, one of the variables remained constant while the other two changed. Obtained identification ratings were plotted as a function of each variable. The results indicated that second formant transition duration and extent contribute significantly to perception. Short second formant transition extents and durations signal stops, while long second formant transition extents and durations signal semivowels. It was found that second formant transition rate did not contribute significantly to this distinction. Any particular rate could signal either a stop or semivowel. These results are interpreted as arguing against models that incorporate transition rate as a cue to phonetic distinctions. In addition, these results are related to a previous selective adaptation experiment. It is shown that the “phonetic” interpretation of the obtained adaptation results was not justified.     

Personality characteristics of androgynous and sex-typed females

Personality characteristics of androgynous and sex-typed females identified by the gem Sex-Role Inventory were studied using the California Psychological Inventory. The results indicated that sex-typed females showed personality characteristics associated with traditional sex-role stereotypes while androgynous females showed both masculine nd feminine characteristics. There was an indication that androgynous and masculine females were better adjusted socially than feminine or undifferentiated females.     

Does Infant-Directed Speech Help Phonetic Learning? A Machine Learning Investigation

A prominent hypothesis holds that by speaking to infants in infant-directed speech (IDS) as opposed to adult-directed speech (ADS), parents help them learn phonetic categories. Specifically, two characteristics of IDS have been claimed to facilitate learning: hyperarticulation, which makes the categories more separable, and variability, which makes the generalization more robust. Here, we test the separability and robustness of vowel category learning on acoustic representations of speech uttered by Japanese adults in ADS, IDS (addressed to 18- to 24-month olds), or read speech (RS). Separability is determined by means of a distance measure computed between the five short vowel categories of Japanese, while robustness is assessed by testing the ability of six different machine learning algorithms trained to classify vowels to generalize on stimuli spoken by a novel speaker in ADS. Using two different speech representations, we find that hyperarticulated speech, in the case of RS, can yield better separability, and that increased between-speaker variability in ADS can yield, for some algorithms, more robust categories. However, these conclusions do not apply to IDS, which turned out to yield neither more separable nor more robust categories compared to ADS inputs. We discuss the usefulness of machine learning algorithms run on real data to test hypotheses about the functional role of IDS.     

Psychotherapie von Anpassungsstörungen

In this study we examined the effectiveness of an outpatient client-centered psychotherapy of patients with adjustment disorders (ICD-10 F43.2) limited to twelve sessions in comparison to an untreated control group. The patients of each group (n_treatment= 31 and n_control= 19) had been diagnosed with an adjustment disorder in response to one of the following stressful events: either the loss of an important person or performance deficits at work or university. Compared with the untreated control group the immediate therapy group improved significantly on rating scales and questionnaires. These positive treatment effects proved stable at a 3 months follow-up. Individual treatment gains were also analyzed for clinical and statistical significance. The improvements of the treatment group were significantly greater in all used measures than those of the control group. These improvements were interpreted as an effect of the client-centered treatment which resulted in high individual overall treatment gains and in high effectsizes.     

What Is Important on the Job? Differences Across Gender,Perspective, and Job Level1

The importance ratings of job competency dimensions on a 360‐degree feedback instrument were examined. We hypothesized that men (incumbents and bosses) would rate agentic behaviors higher in importance than would women, and that women (incumbents and bosses) would rate communal behaviors higher in importance than would men. Differences were found for men and women across rating sources and across job level (organizational position). The present findings suggest that men and women incumbents view different factors as important for their jobs and that people in higher level jobs place more importance on agentic behaviors than do those in lower level positions, and people in lower level jobs place more importance on communal behaviors than do those in higher level positions.     

Working together or separately? The role of identity and cultural self‐construal in well‐being among Japanese youth

Young people develop a sense of personal identity during the transition to adulthood, a time when individuals choose and adhere to a specific set of goals, values, and beliefs. In addition, in many contemporary Asian societies, youth are expected to acquire and balance traditional and Western cultural views of the self — that is, independent and interdependent self‐construal. To understand the relationships between the personal and cultural facets of the transition to adulthood, this study examined (a) associations between personal identity and well‐being and (b) the possible moderating role of cultural self‐construal (independence and interdependence) in this link. These hypotheses were tested in a sample of 520 Japanese university students (52.6% female). The results indicated that personal identity predicted each dimension of well‐being, suggesting that the importance of personal identity in promoting youth's well‐being can be understood as a universal phenomenon. Moreover, because the moderating role of self‐construal in the links between identity and well‐being was found to be limited, personal identity can be viewed as operating separately from self‐construal in well‐being to a large extent. Implications and suggestions for future research are discussed.     

Working mothers versus homemakers: Do dreams reflect the changing roles of women?

In order to examine potential psychological changes arising from women's new social roles, 15 working and 15 nonworking mothers were asked to report dreams collected within a period of three weeks. In addition, they were administered the Jackson Research Personality Form. Two dreams from each subject were analyzed with selected scales which previous studies had shown to be sensitive to sex differences. On the personality inventory, working mothers were found to have higher social recognition and achievement motives. On the dream content measures, discriminant analyses showed that the two groups could be statistically differentiated on the basis of several scales. In accordance with the notion of continuity between waking and dreaming, working mothers experienced more unpleasant emotions, more male characters, and less residential dreams settings than homemakers. The latter group, surprisingly, had more overt hostility in its dreams. These results suggest that as the trend toward carrying the dual role of wage earner and homemaker is expanding, the gender differences typically observed in dreams content may decrease. They also suggest that the analysis of dream content may prove useful to study the strategies of women adapting to role changes.     

Increasing husbands' involvement in domestic labor: Issues for therapists

As a result of the dramatic increase in women's participation in the work force, more relationship therapists are seeing couples who are dissatisfied with how domestic labor is divided in their homes. Although, this issue may seem therapeutically straightforward, there are many aspects which make its renegotiation surprisingly problematic and complex. This article is an effort to delineate some of these issues such as engaging men in therapy, exploring emotional issues connected with housework, and the mechanism of gatekeeping. Also included is a therapeutic framework for addressing client concerns about domestic responsibilities.     

The actions of others as determinants of behavior in social trap situations

Three studies were conducted to determine the effects of observing the behaviors of others upon an individual's actions in a simulated social trap situation. In Experiment 1, it was found that merely having the opportunity to make comparative appraisals of the actions of others led to greater competition for a finite common resource than when subjects were physically isolated from one another. In Experiment 2, false feedback was given to subjects to determine if the actions of others alone were responsible for the deleterious effects of having the opportunity for comparative appraisal; it was found that subjects quickly conformed to the behavior pattern of the interacting others, regardless of whether the false feedback indicated that the other subjects were consuming more or less than no-treatment control subjects. Experiment 3 was conducted to determine the motivation of subjects reacting to the actions of others; differential predictions based upon a competition/relative outcome explanation and upon an information search explanation were made. The data were consistent with the information search explanation.
