小学二年级学生汉语阅读知觉广度的眼动研究

小学生阅读知觉广度是阅读发展心理学中的一个基本问题。本研究以Eyelink 1000 plus眼动仪为工具,采用2（年龄）×5（窗口）的两因素混合实验设计,考察小学二年级学生汉语阅读的知觉广度。结果显示,二年级学生的知觉广度为右侧1-2个汉字。二年级小学生快慢读者在眼动指标上存在差异,但未发现在知觉广度上存在差异。阅读能力测验与眼动指标存在显著的相关,此外小学二年级学生的阅读速度可以预测学业成绩。     

A theoretical analysis of the perceptual span based on SWIFT simulations of the n + 2 boundary paradigm

Eye-movement experiments suggest that the perceptual span during reading is larger than the fixated word, asymmetric around the fixation position, and shrinks in size contingent on the foveal processing load. We used the SWIFT model of eye-movement control during reading to test these hypotheses and their implications under the assumption of graded parallel processing of all words inside the perceptual span. Specifically, we simulated reading in the boundary paradigm and analysed the effects of denying the model to have valid preview of a parafoveal word n + 2 two words to the right of fixation. Optimizing the model parameters for the valid preview condition only, we obtained span parameters with remarkably realistic estimates conforming to the empirical findings on the size of the perceptual span. More importantly, the SWIFT model generated parafoveal processing up to word n + 2 without fitting the model to such preview effects. Our results suggest that asymmetry and dynamic modulation are plausible properties of the perceptual span in a parallel word-processing model such as SWIFT. Moreover, they seem to guide the flexible distribution of processing resources during reading between foveal and parafoveal words.     

Psychosocial Predictors of Wellness in College Students

The authors examined how the first 6 stages of psychosocial development predict wellness in undergraduate college students using the Measures of Psychosocial Development (Hawley, 1988 ) and the Perceived Wellness Survey (Adams, Bezner, & Steinhardt, 1997 ). Results indicated that 4 of the 6 stages predict wellness in college students. Clinical implications for counselors of this population are provided.     

Testing the redintegration hypothesis by a single probe recognition paradigm

The lexicality effect in verbal short-term memory (STM), in which word lists are better recalled than nonwords lists, is considered to reflect the influence of linguistic long-term memory (LTM) knowledge on verbal STM performance. The locus of this effect remains, however, a matter of debate. The redintegrative account considers that degrading phonological traces of memoranda are reconstructed at recall by selecting lexical LTM representations that match the phonological traces. According to a strong version of this account, redintegrative processes should be strongly reduced in recognition paradigms, leading to reduced LTM effects. We tested this prediction by contrasting word and nonword memoranda in a fast encoding probe recognition paradigm. We observed a very strong lexicality effect, with better and faster recognition performance for words as compared to nonwords. These results do not support a strong version of the redintegrative account of LTM effects in STM which considers that these LTM effects would be the exclusive product of reconstruction mechanisms. If redintegration processes intervene in STM recognition tasks, they must be very fast, which at the same time provides support for models considering direct activation of lexico-semantic knowledge during verbal STM tasks.     

Locke's theory of reflection

This paper examines the nature of ‘reasonable’ (eulogos) argumentation in Generation of Animals III.10. Its aim is to develop an alternative to the dialectical construal of reasonable argumentation in Aristotle recently favoured by Robert Bolton. On the basis of a close textual analysis I show that the reasonable arguments deployed in Generation of Animals III.10 do not appeal to endoxa or reputable beliefs per se. Instead, they rely upon general facts (sumbainonta) about animals established by empirical induction. This implies that, contra Bolton, not all reasonable arguments in Aristotle are dialectical; some, in fact, are thoroughly empirical and scientific. I conclude by suggesting that such empirical reasonable arguments even have a place in the De Caelo, the treatise that Bolton primarily focused upon when developing his interpretation.     

Distortions in reports of health behaviors: The time span effect and illusory supefuority

Abstract

The occurreace of a time span effect and illusory superiority in self reports of health behaviors was tested. It was found that people report proportionally lower frequencies of both healthy and unhealthy behaviors if they give frequency estimations over a longer as compared to a shorter time span (time span effect). In addition, they report lower frequencies of unhealthy behaviors, and higher frequencies of healthy behaviors for themselves than for the average other (illusory superiority). For healthy but not for unhealthy behaviors a stronger illusory superiority effect was obtained in frequency reports for behavioral expectations as compared to past behaviors. Potential explanations and implications for subjective measurements of health behavior are discussed.     

Developmental differences in working memory: Where do they come from?

Several models assume that working memory development depends on age-related increases in efficiency and speed of processing. However, age-related increases in the efficiency of the mechanisms that counteract forgetting and restore memory traces may also be important. This hypothesis was tested in three experiments by manipulating both the processing duration within a working memory task and the time available to restore memory traces. Third- and sixth-grade children performed a complex span task in which they maintained series of letters while adding numbers to series of digits. When we equated processing and restoration times between ages, the developmental difference in working memory span was reduced but remained significant. However, this residual difference was eliminated when the time available to reactivate memory traces was tailored to the processing speed of each age group. This indicates that children employ active mechanisms for maintenance and restoration of memory traces that develop with age.     

From Ages 27 to 72: Career and Personal Development of a Productive Counselor Over the Life Span

Interviews of productive counselors usually do not capture their adult life span in depth. This article examines the life of a prolific counselor over 5 decades in context and through the theories of personal and career development formulated by Erikson ( 1994 ) and Super ( 1980 ). It looks biographically at his life and its challenges as well as resolutions to difficulties he faced in the process. Lessons that have universal application are highlighted.
