Factor structure of the Center for Epidemiological Studies Depression Scale in Hong Kong adolescents

We present data from the Center for Epidemiological Studies-Depression Scale (CES-D; Radloff, 1977) for 2 samples of Hong Kong community adolescents (combined N = 1,385). The 4 positive affect items related poorly to the remainder of the scale. Using 16 items, the data were consistent with 2 models with highly correlated factors: (a) a 2-factor model, 1 of which merged somatic and affective items, and (b) a 3-factor model separating somatic, depressed, and interpersonal items. Correlations with related constructs provide preliminary support of validity. Hong Kong adolescents are influenced both by traditional concepts of mind-body holism and Western psychological models separating psychological and somatic symptoms.     

Esteem maintenance among groups: Laboratory and field studies of group performance cognitions

Across 48 experimental groups, those that scored higher on group self-esteem attributed perceived positive outcomes to internal factors and negative outcomes to external factors. Groups provided more elaborate rationalizations about perceived negative outcomes and less elaborate rationalizations about perceived positive outcomes. They also espoused greater confidence in improved performance after negative outcomes and less confidence following positive outcomes. Similar findings were observed among 252 intact work groups in an employment setting. We discuss the implications of these findings for understanding how group self-esteem influences how groups evaluate and respond to performance feedback.     

Classroom discourse analysis and educational outcomes in the era of education reform

Background In the era of education reform when new teaching approaches are being advocated, it is important to investigate how different classroom discourse patterns are related to different educational outcomes. Aim The purpose of the study was to analyse the whole classroom discourse of two teacher interns' writing classes. It was conducted against a background of education reform in which teachers were being encouraged to make major changes in their teaching approaches. We investigated what approaches were adopted and what discourse patterns were related to better educational outcomes. Sample The participants were two teacher interns and their 61 students in Hong Kong. The students (35 boys, 26 girls) were seventh graders from two classes in the same secondary school. Method An instruction unit of each teacher intern on expository writing (120 min) was video‐recorded and analysed. Discourse analysis of the whole classroom interaction was supplemented by the students' perceptions and independent observers' evaluations of the instruction. Results The results indicated that both teacher interns adopted a traditional direct instruction although student‐centred approaches were being recommended in the education reform. The effectiveness of the instruction was associated with certain features of the classroom discourse patterns. Better educational outcomes were associated positively with utterances of high cognitive demand but negatively with utterances related to discipline. Students tended to have better performances in writing when they and the independent observers perceived that the teachers used more motivating strategies. Conclusions The effectiveness of instruction is a complicated phenomenon that involves a myriad of interrelated factors. Teacher‐ or student‐centred approaches are only part of these diverse factors.     

Cultural differences in gender role attitudes between Chinese and American students

A total of 665 Chinese college students in Taiwan and Caucasian college students in eastern North Carolina were administered several sex role attitude scales developed by Spence et al. (1978, 1980). The scales were translated into Chinese for Chinese subjects. Results indicated cultural differences in attitudes toward Marital Roles, Expressivity, Social Interaction, and Preference for males. In both cultures, females were found to be significantly more liberal, as shown in Attitudes Toward Women, Marital Roles, and Social Interaction. These results are consistent with previous research. Cultural differences were also as expected, with Chinese holding more conservative views.An earlier version of this paper was presented in part at the 63rd Annual Convention of the Eastern Psychological Association, Boston, Massachusetts, April 3, 1992.     

Kanizsa's shrinkage illusion produced by a misapplied 3-D corrective mechanism

In order to include the monocular areas from the left and the right eye in the cyclopean view, the visual system displaces the occluded elements which would result in a horizontal elongation of the shape but does not occur thanks to a correction mechanism which preserves the shape. We hypothesised that this mechanism causes Kanizsa's amodal shrinkage illusion (the apparent elongation of a partially occluded square) when it is incorrectly applied by the visual system to a two-dimensional stimulus. Four experiments tested this hypothesis: (i) one-eyed observers were less susceptible to the illusion than people with normal binocular vision because, for them, the correction for shape is unnecessary; (ii) the illusion was stronger with binocular than with monocular vision since binocularity induces the visual system to correct for the shape distortion; (iii) the illusion diminished when the stimulus was rotated 90 degrees given that displacement and compression are not required for vertical occlusion; (iv) the magnitude of the illusion was a function of the width of the occluder because, as previous research has shown, the edges of a partially occluded square are less displaced the farther they are from the edges of the occluder. The data from the four experiments support our hypothesis even though no condition was able to eliminate the illusion; other possible causes are discussed.     

Mommy, speak clearly: induced hearing loss shapes vowel hyperarticulation

Talkers hyperarticulate vowels when communicating with listeners that require increased speech intelligibility. Vowel hyperarticulation is said to be motivated by knowledge of the listener's linguistic needs because it typically occurs in speech to infants, foreigners and hearing-impaired listeners, but not to non-verbal pets. However, the degree to which vowel hyperarticulation is determined by feedback from the listener is surprisingly less well understood. This study examines whether mothers' speech input is driven by knowledge of the infant's linguistic competence, or by the infant's feedback cues. Specifically, we manipulated (i) mothers' knowledge of whether they believed their infants could hear them or not, and (ii) the audibility of the speech signal available to the infant (full or partial audibility, or inaudible). Remarkably, vowel hyperarticulation was completely unaffected by mothers' knowledge; instead, there was a reduction in the degree of hyperarticulation such that vowels were hyperarticulated to the greatest extent in the full audibility condition, there was reduced hyperarticulation in the partially audible condition, and no hyperarticulation in the inaudible condition. Thus, while it might be considered adaptive to hyperarticulate speech to the hearing-impaired adult or infant, when these two factors (infant and hearing difficulty) are coupled, vowel hyperarticulation is sacrificed. Our results imply that infant feedback drives talker behavior and raise implications for intervention strategies used with carers of hearing-impaired infants.     

The Structural Metaphysics of Quantum Theory and General Relativity

The paper compares ontic structural realism in quantum physics with ontic structural realism about space–time. We contend that both quantum theory and general relativity theory support a common, contentful metaphysics of ontic structural realism. After recalling the main claim of ontic structural realism and its physical support, we point out that both in the domain of quantum theory and in the domain of general relativity theory, there are objects whose essential ways of being are certain relations so that these objects do not possess an intrinsic identity. Nonetheless, the qualitative, physical nature of these relations is in the quantum case (entanglement) fundamentally different from the classical, metrical relations treated in general relativity theory.
