中文阅读过程中的副中央凹预视效应

副中央凹预视效应指当读者正注视某个词(即位于中央凹的词n)时, 可以获得词n右侧词(即位于副中央凹词n+1或词n+2)的部分信息。在阅读过程中读者能否从副中央凹预视到信息, 会直接影响他们的阅读效率。因此, 探讨阅读过程中的副中央凹预视效应产生的条件、影响因素及机制, 成为阅读心理学需要解决的基本问题之一。本文系统总结了中外文阅读过程中副中央凹预视效应的研究进展, 包括副中央凹预视效应的研究范式, 中外文阅读过程中副中央凹预视的信息类型、不同类型信息预视加工的时间进程, 以及空间上获得预视信息的范围。最后提出中文阅读过程中副中央凹预视研究需要解决的几个关键问题。     

Broadcasting of violence on Spanish television: a quantitative panorama

A quantitative analysis of broadcasted violence by the main television (TV) channels transmitting for Madrid (Spain) was carried out using a novel method that randomly selects fragments of delimited duration from TV broadcasts. The device selects acts of aggression shown in those TV extracts, and classifies them according to their type. There was a high incidence of aggressive acts, especially physical (particularly leading to death), in TV fiction: films, serials and promos. The device also allowed examination of the prominence of aggression in children's programs, as well as showing minimal variation in the number of aggressive acts over screened time intervals. The pattern of the collected data suggests that the broadcasting of violence on TV emphasizes the conflicting elements of social reality, reproducing it in fiction, news reports and children's shows.

On the Metaphysics of Linguistics

Mind–body dualism has rarely been an issue in the generative study of mind; Chomsky himself has long claimed it to be incoherent and unformulable. We first present and defend this negative argument but then suggest that the generative enterprise may license a rather novel and internalist view of the mind and its place in nature, different from all of, (i) the commonly assumed functionalist metaphysics of generative linguistics, (ii) physicalism, and (iii) Chomsky’s negative stance. Our argument departs from the empirical observation that the linguistic mind gives rise to hierarchies of semantic complexity that we argue (only) follow from constraints of an essentially mathematical kind. We assume that the faculty of language tightly correlates with the mathematical capacity both formally and in evolution, the latter plausibly arising as an abstraction from the former, as a kind of specialized output. On this basis, and since the semantic hierarchies in question are mirrored in the syntactic complexity of the expression involved, we posit the existence of a higher-dimensional syntax structured on the model of the hierarchy of numbers, in order to explain the semantic facts in question. If so, syntax does not have a physicalist interpretation any more than the hierarchy of number-theoretic spaces does.     

Repetition costs in word identification: evaluating a stimulus–response integration account

Stimulus repetition facilitates performance in many experimental contexts. However, an episodic approach to interpreting repetition effects suggests that repetition effects should depend on how stimuli are encoded. In Experiments 1-3, stimulus repetition in a word identification task led to a cost rather than a benefit in performance, but only when the prime was presented for a relatively long duration. One account of these results is that long prime durations allow integration between stimulus and response codes to occur, which in turn can interfere with responding to a following identical target. In Experiment 4, a stimulus intensity based episodic specificity effect that was insensitive to the proportion of repeated trials supported this stimulus-response integration account.     

Semantic priming effects from single words in a lexical decision task

The present research examines the semantic priming effects of a centrally presented single prime word to which participants were instructed to either "attend and remember" or "ignore". The prime word was followed by a central probe target on which the participants made a lexical decision task. The main variables manipulated across experiments were prime duration (50 or 100 ms), the presence or absence of a mask following the prime, and the presence (or absence) and type of distractor stimulus (random set of consonants or pseudowords) on the probe display. There was a consistent interaction between the instructions and the semantic priming effects. Relative to the "attend and remember" instruction, an "ignore" instruction produced reduced positive priming from single primes presented for 100 ms, irrespective of the presence or absence of a prime mask, and regardless of whether the probe target was presented with or without distractors. Additionally, reliable negative priming was found from ignored primes presented for briefer durations (50 ms) and immediately followed by a mask. Methodological and theoretical implications of the present findings for the extant negative priming literature are discussed.     

Telepsychology and Self-help: The Treatment of Fear of Public Speaking

This work presents a self-help, Internet-based telepsychology program for the treatment of public speaking fears. The system is comprised of 3 parts: The assessment protocol gives the patient information about his or her problem (i.e., amount of interference it creates in his or her life, severity, degree of fear and avoidance). The system also includes a structured treatment protocol, organized into separate blocks, reflecting the patient’s progress. This ensures that the patient does not skip any steps in the treatment (something quite common in traditional self-help manuals), which provides more control over the process. The treatment protocol is a cognitive-behavioral program that provides exposure to the feared situation using videos of real audiences. Finally, the control protocol assesses treatment efficacy, not only at closure, but also at every intermediate step. Efficacy data from 12 social phobia patients are presented from pretreatment to posttreatment and at 1-month follow-up. These preliminary data support the efficacy of our telepsychology program for the treatment of fear of public speaking. This is a preliminary work in a promising research path that examines the possibility of using the Internet for the treatment of psychological disorders.     

Computer speech-based remediation for reading disabilities: the size of spelling-to-sound unit in a transparent orthography

This study was designed to assess the effects of four reading-training procedures for children with reading disabilities (RD) in a transparent orthography, with the aim of examining the effects of different spelling-to-sound units in computer speech-based reading. We selected a sample of 83 Spanish children aged between 7 years 1 month and 10 years 6 months (M = 105.2, SD = 7.8) whose pseudoword reading performance was below the 25th percentile and IQ > 90. The participants were randomly assigned to five groups: (a) the whole-word training group (WW) (n = 17), (b) the syllable training group (S)(n = 16), (c) the onset-rime training group (OR) (n = 17), (d) the phoneme training group (P) (n = 15), and (e) the untrained control group (n = 18). Children were pre- and post-tested in word recognition, reading comprehension, phonological awareness, and orthographic and phonological tasks. The results indicate that experimental groups who participated in the phoneme and syllable conditions improved their word recognition in comparison with the control group. In addition, dyslexics who participated in the phoneme, syllable, and onset-rime conditions made a greater number of requests during computer-based word reading under conditions that required extensive phonological computation (low frequency words and long words). Reading time, however, was greater for long words in the phoneme group during computer-based reading. These results suggest the importance of training phonological processes in improving word decoding in children with dyslexia who learn in a consistent orthography.

轻度认知损伤（Mild cognitive impairment,MCI）是介于正常老化与痴呆之间的过渡阶段,表现为与年龄和教育程度不相称的认知功能减退。本文回顾了近期有关MCI语义记忆的研究,分析比较了各研究的实验任务及结果,得出MCI患者存在一定程度的由多种原因造成的语义记忆损伤,语义记忆测验对MCI的早期筛查和转归预测有重要作用。最后指出将来的研究需要将包括语义记忆成分在内的多种认知测验相结合,以便及早发现有可能发展为痴呆的危险个体并开展相应干预。
