“ACCENTUATION EFFECTS” OF DISSIMILAR ACADEMIC DEPARTMENTS: An Application and Exploration of Holland's Theory

This longitudinal study of college students found accentuation of initial group differences among academic subenvironments for Artistic abilities of both male and female students and for Enterprising abilities of male students. It also showed that male and female students in Artistic subenvironments-for whom Artistic abilities and interests were each of the two gender groups' initially prominent characteristic-increased still further in score on the Artistic abilities and interest scale over four years of college; and parallel results were found for male students in Enterprising subenvironments in terms of Enterprising abilities and interests. Moreover, both male and female students initially high on Artistic and Enterprising abilities and interests gained more on these attributes if they entered congruent academic subenvironments (Artistic and Enterprising subenvironments, respectively) than if they entered any of the other subenvironments. Whereas these findings support Holland's theory, other data (primarily for Investigative and Social abilities and interests of students) were either less supportive or unsupportive of Holland's theory. Some implications of these results are discussed.     

Processing procedural documents: A cognitive model for following written directions

This paper reviews empirical literature on how people use documents to perform tasks. We examine studies that have been published under the topics of: following written directions, reading maps, following instructions, using job performance aids, and processing procedural texts. Documents that contain a procedure, such as a set of directions, require transformation of information. Such transformation frequently requires converting a procedure represented verbally in a text into a procedure represented behaviorally in a performance. To accomplish this transformation, we propose that students must: (a) form a conceptual model of the performance; (b) encode procedures from the document; (c) engage in self-testing; and (d) conduct self-corrections to repair mistakes. We further propose that these operations are performed most efficiently with distinctive information resources. An overview of the task is likely to be most effective in facilitating conceptual model formation. Procedural information that emphasizes temporal characteristics of the performance will facilitate the encoding of procedures. A representation of the outcome (usually graphic) improves self-testing, and the comparison of the outcome with progress in the workspace leads to most effective self-correction. This process-resource interaction minimizes the number and complexity of transformations required to process procedural documents.     

Information processing in seven-month-old infants as a function of risk status

7-month-old full-terms and high-risk preterms (less than 1,500 grams at birth) were compared on problems of visual recognition memory and tactual-to-visual cross-modal transfer. On the visual problems, preterm infants showed significantly less differential attentiveness to novelty than full-terms. They also required longer exposure times during visual familiarization, primarily because of longer pauses between fixations. Preterms and full-terms exhibited different patterns of looking, as indicated by the duration of fixation and the frequency in shifts of gaze. On the cross-modal problems, preterms and full-terms both exhibited similar and significant preferences for familiar rather than novel stimuli, a direction of preference which suggests that these problems were relatively difficult for both groups. For the preterms, novelty and exposure-time scores were found to be related to several medical risk factors. Novelty preferences were compromised in preterms who had suffered RDS postnatally, particularly those who had required prolonged mechanical ventilation. In general, high-risk preterms exhibited deficits in visual recognition memory and in the ability to recruit, sustain, and shift attention.     

The effects of preexposure to a warning or a safety signal on the acquisition of a two-way avoidance response in rats

Rats that were given nonreinforced preexposure to either a warning signal or a safety signal were significantly retarded in the subsequent learning of a two-way shock-avoidance response compared to rats that were not preexposed. These results are consistent with Mackintosh’s “learned-irrelevance” formulation of latent inhibition. They do not support a prediction derived from an extension of Kalat and Rozin’s “learned-safety” hypothesis. These findings suggest that preexposures in the total absence of aversive events do not endow a stimulus with safety properties.

Letter names, letter sounds and phonological awareness: an examination of kindergarten children across letters and of letters across children

In this study 149 kindergarten children were assessed for knowledge of letter names and letter sounds, phonological awareness, and cognitive abilities. Through this it examined child and letter characteristics influencing the acquisition of alphabetic knowledge in a naturalistic context, the relationship between letter-sound knowledge and letter-name knowledge, and the prediction of Grade 1 phonological awareness and word identification from these variables. Knowledge of letter sounds was better for vowels and for letters with consonant–vowel names than for those with vowel–consonant names or names bearing little relationship to their sounds. However, there were anomalies within each category reflecting characteristics of the individual letters. Structural equation modelling showed that cognitive ability, comprising receptive vocabulary, non-verbal reasoning, rapid automatized naming of colours, and phonological memory significantly contributed to alphabetic knowledge and phonological awareness. In turn, letter-name knowledge but not phonological awareness predicted letter-sound knowledge and subsequent reading skill.This research was supported by a grant from the Social Sciences and Humanities Research Council of Canada to the first author. Thank you is extended to the participating schools and children and to Ian Newby-Clark for his orientation to AMOS.

人类极限

去年12月一位64岁的德鲁斯老妇摔倒在冰上,由于关节炎而无法站立。她在雪中躺了好几个小时,体温降至70华氏度（约21摄氏度）,心跳一度停止,生命垂危。但在医生的抢救下恢复了过来。现代医学仍在研究人类身体承受的极限,但杜克大学的医师德劳德·皮恩塔多斯称过了某个临界点,医生也无力回天。以下就是关于人类承受极限的一些数值。     

Helpful components involved in the cognitive-experiential model of dream work

The purpose of the study was to examine the helpful components involved in the Hill’s cognitive-experiential dream work model. Participants were 27 volunteer clients from colleges and universities in northern and central parts of Taiwan. Each of the clients received 1–2 sessions of dream interpretations. The cognitive-experiential dream work model was applied to these clients by three therapists. The processes of the dream work were audio-taped and transcribed verbatim. The transcribed data, which included a total of 38 sessions for the 27 clients, were analyzed by the Consensus Qualitative Research (CQR) approach to examine the helpful components of the dream work. The results indicated that the general and typical helpful components involved in the process of dream interpretation included four domains: waking-life association, parts of self exploration, gaining insight, and action ideas.
