Speech clarity/intelligibility: test-retest reliability of magnitude-estimation scaling

The reliability of magnitude-estimation scaling as a measure of overall clarity of speech was investigated. 40 subjects (M age = 19 yr.) provided magnitude-estimation responses for nine audiotaped versions of a nonsense sentence varying systematically in number of correct consonant phonemes. There was no significant difference in the magnitude-estimation responses of the subjects during two test sessions separated by one week. Analysis suggested that magnitude-estimation scaling is a reliable measure of speech clarity/intelligibility. This finding is discussed in relation to speech samples varying in aspects other than number of consonant phonemes correct and possible further clinical research applications.     

Development of Component Skills in Reading Chinese

Development of three component skills in reading Chinese was examined in primary school children in Hong Kong. Feature analysis skills, syntax knowledge, and semantic analysis skills were found to differ in their contribution to reading proficiency at different grades. Visual processing skill was not at all a good predictor for reading proficiency, but the phonological access skill was important in predicting children's reading proficiency before grade three. It was an ineffective predictor beyond grade three. Skill in semantic analysis, on the other hand, was insignificant as a predictor at younger grades but it became an important predictor after grade two. Syntax knowledge was an important predictor of reading proficiency in the first grade and remained a significant predictor of reading proficiency right up to grade six. The present data support the idea that some preliminary component processes of reading may become automatic with increasing experience in reading and that this automatization of component processes will leave more resource capacity for higher-order analyses. Chinese reading shares much in common with English reading in terms of the component processes involved at different stages of reading proficiency.     

Sampling distributions of the entropy in visual scanning

Identifying true statistical dependencies in visual-scanning data involves showing that the observed scanning pattern is significantly more ordered than that which would be produced by a stratified random-sampling model. In the past, entropy has been used as the index to measure statistical order or dependency. Due to the unknown nature of the underlying sampling distributions of entropy, however, researchers have had to use relatively less powerful nonparametric statistical tests to determine significance. In this paper we present relevant portions of the family of sampling distributions of entropy and show that they are sufficiently normally distributed to allow the use of a more powerful parametric statistical test when attempting to distinguish among the different models of sampling.     

EVALUATION OF ATTITUDE SURVEY TRANSLATIONS: AN INVESTIGATION USING ITEM RESPONSE THEORY

The fidelity of a translated survey instrument used to measure attitudes toward mental health was evaluated using statistical methods based on item response theory. Data from French and German versions of the attitude survey were analyzed, and items that displayed differential item functioning (dif) were identified. Item characteristic curves (ICCs) were examined to determine whether the source of dif could be attributed to errors in translation or differences in cultural experiences or knowledge. The proposal by Humphreys and Hulin for using ICCs to determine the source of dif is evaluated.     

The voices in children's literature: The impact of gender on the moral decisions of storybook characters

The study examined the moral and self orientations of 212 male and female characters in 50 works of fiction for school-aged children. A modified version of Lyons' coding scheme was used for differentiating between Justice and Care moral orientations, and Separate/Objective and Connected self orientations. It was hypothesized that male characters would demonstrate Justice morality and a Separate/Objective self, whereas female characters would demonstrate Care morality and a Connected self, regardless of sex of author. The results confirmed the hypotheses. The importance of literature in providing symbolic models of moral decisioning and the need to expand children's moral orientations beyond gender-linked stereotypes was discussed.An earlier version of this paper was presented at the annual meeting of the American Educational Research Association, April 1988, New Orleans, Louisiana.     

The relationship between sex role identity and marital adjustment

One hundred forty-four maritally distressed clinic couples and 138 nonclinic couples participated in a study investigating the relationship between individual sex role identity and marital adjustment. Subjects completed Baucom's (1976) masculinity (MSC) and femininity (FMN) scales, and either the Dyadic Adjustment Scale (DAS; Spanier, 1976) or the Marital Adjustment Scale (MAS; Locke & Wallace, 1959). As predicted, femininity was related to positive marital adjustment; masculinity was related as well, but perhaps to a lesser degree. Androgyny within a relationship was found to be highly desirable, whereas marriages involving undifferentiated individuals were more likely to be distressed.     

New directions for family therapy: rubbish removal as a task of choice

Family therapy may be accompanied by laughter and wit as well as serious labour. Family life has a great deal to laugh about, and family therapists, if they take families seriously, need to be able to laugh and joke with them.
