Corpora of Vietnamese Texts: Lexical effects of intended audience and publication place

This article has two primary aims. The first is to introduce a new Vietnamese text-based corpus. The Corpora of Vietnamese Texts (CVT; Tang, 2006a) consists of approximately 1 million words drawn from newspapers and children's literature, and is available online at www.vnspeechtherapy.com/vi/CVT. The second aim is to investigate potential differences in lexical frequency and distributional characteristics in the CVT on the basis of place of publication (Vietnam or Western countries) and intended audience: adult-directed texts (newspapers) or child-directed texts (children's literature). We found clear differences between adult- and child-directed texts, particularly in the distributional frequencies of pronouns or kinship terms, which were more frequent in children's literature. Within child- and adult-directed texts, lexical characteristics did not differ on the basis of place of publication. Implications of these findings for future research are discussed.     

Data management and accountability in behavioral and biomedical research.

Regulations recently enacted by the Public Health Service and the National Science Foundation to address misconduct in scientific research were designed primarily to curtail deliberate forms of misconduct, such as fabrication or falsification of findings; however, researchers may also be held accountable for inadvertent deficiencies in data management. This article examines some of the problems in data quality control, documentation, and data retention that can occur when computers are used in scientific research. It focuses on deficiencies that could make it difficult to verify the integrity of research data or to reproduce statistical analyses. Strategies for prevention of data management problems are recommended.     

Controlling behavior experiments with BASIC on 6502-based microcomputers

A combination of high-level BASIC and transparent machine language routines forms an inexpensive (about $800), powerful, and easy-to-use microcomputer system for behavior research, based on the AIM-65. The interrupt-driven machine language routines keep track of real time, poll inputs, and are not typically modified for different experiments. Expandable machine language listings that support eight input lines and eight output lines on the AIM-65 are presented. The user-written BASIC program controls experiments and records data. BASIC programs for simple reinforcement schedules are used as examples. The software is readily transferred to other 6602-based microcomputers with BASIC.     

A comparison of EMG and SCL in normal and depressed subjects

Skin conductance level (SCL) and electromyograms (EMGs) recorded from three muscle sites were compared for 15 female hospitalized psychiatric patients meeting diagnostic criteria for primary affective disorder and 15 age- and race-matched controls. The depressed subjects had significantly lower SCL and significantly higher resting EMG levels recorded from one muscle site. Electromyogram and SCL were not found to be significantly correlated with each other or with measures of anxiety or depression for the patients with primary affective disorder. Normal controls, however, showed significant correlations between a measure of depression and both EMG and SCL. These results are discussed with suggestions for future research.     

Intellectual development and its relationship to maturation during the college years

This study examines whether differences in the development of critical reasoning abilities among undergraduates can be attributed to factors other than college attendance, and specifically to differences in chronological maturation. Eight males and eight females were randomly selected and matched on ACT composite scores from each of four groups: 18-year-old freshmen; 22-year-old freshmen; 22-year-old seniors; and 26-year-old seniors. Theses 64 subjects were arranged within a non-assignable three factor design by age (adult and traditional), class level (freshman and senior), and sex. Subjects were administered the Reflective Judgment Interview, a structured interview format designed to measure the way individuals reason about intellectual problems. Two significant main effects were observed, with seniors scoring higher than freshman (p < .001), and males scoring higher than females. The class level main effect, in the absence of any significant difference of reflective judgment level due to age, suggests that college attendance does contribute to the development of critical reasoning beyond the factor of chronological maturation. An explanation for significant sex differences found is not clearly discernible from these data.     

Effects of eye size on adults' aesthetic ratings of faces and 5-month-olds' looking times

In two experiments, we investigated the influence of eye size on adults' ratings of faces' attractiveness and 5-month-olds' looking times. Subjects viewed four pairs of female faces that were identical except for the size of the eyes. Whether they saw black-and-white drawings (experiment 1) or coloured photographs (experiment 2), adults rated the faces with larger eyes as more attractive than the faces with smaller eyes. Babies looked equally long at the drawn faces with larger and smaller eyes (experiment 1), but with the more realistic photographed faces, they looked slightly but significantly longer at the versions with larger eyes (experiment 2). Overall, our results suggest that a modest preference for larger eyes that has emerged by 5 months of age may contribute to the development of adult aesthetic preferences.     

The relationship between vocational information seeking and educational and vocational decidedness

This investigation explored the relationship between vocational information seeking behavior (VISB) and educational and vocational decidedness. Pre- and postmeasures of VISB and educational and vocational decidedness were given to two groups of “undecided” university freshmen. One group experienced a 3-hr long vocationally oriented life planning workshop and a career planning class module of 10 hr duration; the other experienced only the class module. Correlations between VISB and the two forms of decidedness were low but significant. Cross-lagged and dynamic correlations completed to determine causal effects only minimally supported the hypotheses that engaging in VISB produces an increase in educational and vocational committedness and vice versa. Some possible explanations for this finding are discussed.

Can we modify maladaptive attributions for fatigue?

Research has shown that those with insomnia focus primarily on their sleep as a cause of daytime fatigue rather than the multitude of other possible causes of fatigue. This can create sleep-related anxiety and further perpetuate the sleep disturbance. In order to lessen the increased focus on sleep, the present study investigated whether people could learn to consider other attributions for fatigue via an information-based manipulation. Undergraduate students (N = 88) were randomized to two information groups: They either received information about common factors that could explain daytime fatigue (the fatigue information condition) or received generic sleep-related information (the control condition). Each group was tested pre- and post-intervention. Fatigue information participants were significantly more likely to consider non-sleep-related attributions for fatigue at post-intervention, relative to control participants. These results demonstrate that attributions for fatigue may be amenable to change via an information-based intervention; thus, this research explores a preliminary step toward investigating refinements to insomnia treatments.
