非言语声音影响汉语听者言语声音的知觉

采用启动范式, 以汉语听者为被试, 考察了非言语声音是否影响言语声音的知觉。实验1考察了纯音对辅音范畴连续体知觉的影响, 结果发现纯音影响到辅音范畴连续体的知觉, 表现出频谱对比效应。实验2考察了纯音和复合音对元音知觉的影响, 结果发现与元音共振峰频率一致的纯音或复合音加快了元音的识别, 表现出启动效应。两个实验一致发现非言语声音能够影响言语声音的知觉, 表明言语声音知觉也需要一个前言语的频谱特征分析阶段, 这与言语知觉听觉理论的观点一致。     

教养方式、气质对青少年攻击的影响：独特、差别与中介效应检验

运用“多前因变量－多结果变量”框架, 探讨教养方式、气质对青少年直接和间接攻击有无独特效应与差别效应, 以及规范信念(认为攻击他人是正确和可接受的)在其中的中介作用。660名青少年(平均年龄14.14岁, 女生364人)报告了教养方式、气质特征、攻击信念和攻击行为的情况。多重和多元回归分析表明：(1)教养方式(权威、专制、纵容)对直接攻击独特效应不显著, 气质(意志控制、愤怒挫折、感觉寻求)对直接攻击有独特效应; 教养方式(权威、专制、纵容)和气质(意志控制、感觉寻求)对间接攻击有独特效应。(2)教养方式(权威、专制、纵容)与直接攻击的联系显著弱于其与间接攻击的联系, 而气质(愤怒挫折、感觉寻求)与直接攻击的联系则显著强于其与间接攻击的联系。(3)两类规范信念与两类攻击具有不完全的特异性联系, 而且直接规范在气质(意志控制、感觉寻求)与两类攻击之间具有中介作用, 间接规范在教养方式(权威)与间接攻击、气质(愤怒挫折)与两类攻击之间具有中介作用。因此, 教养方式和气质对不同形式攻击行为的影响不同, 且这种影响可以部分地由规范信念加以解释。     

基于数量感知的数量适应

数量适应是指观察者在知觉上适应刺激数量的过程, 这一过程可以通过考察适应后其数量感知的变化加以揭示。目前对这一现象的争论焦点在于它是对数量的单独适应还是对非数量表面信息的适应。本研究通过改变刺激点大小和刺激组块两种方式, 探讨非数量表面信息对数量感知和数量适应的影响。实验一证明刺激点大小不会对数量感知产生显著影响。实验二发现刺激组块会对数量感知产生显著影响。实验三在前两个实验基础上发现：刺激大小不对数量感知产生显著影响, 也不影响数量适应, 而刺激组块能显著改变数量感知, 并按照改变后的数量感进行适应。三个实验的结果说明：表面信息只有在影响到数量感知时才会影响适应, 数量适应是基于数量感知的加工而产生的适应现象。     

不良生活方式作用途径及其控制

不良生活方式影响健康的途径包括：病从口入;生活放纵造成机体的衰竭;享受型生活方式“废用”性的机体退化;生活中的失慎与失范导致直接的伤亡;生活压力导致的机体受损;挑战生理极限的心理、生理代价．改变不良生活方式应当遵从科学的原则和一定的标准。

Daily Behavior Report Cards and Systematic Direct Observation: An Investigation of the Acceptability,Reported Training and Use,and Decision Reliability Among School Psychologists

More than ever, educators require assessment procedures and instrumentation that are technically adequate as well as efficient to guide data-based decision making. Thus, there is a need to understand perceptions of available tools, and the decisions made when using collected data, by the primary users of those data. In this paper, two studies that surveyed members of the National Association of School Psychologists with regard to two procedures useful in formative assessment, (i.e., Daily Behavior Report Cards; Systematic Direct Observation), are presented. Participants reported greater overall levels of training and use of Systematic Direct Observation than Daily Behavior Report Cards, yet both techniques were rated as equally acceptable for use in formative assessment. Furthermore, findings supported that school psychologists tend to make similar intervention decisions when presented with both types of data. Implications, limitations, and future directions are discussed.     

Perceptual adaptation to non-native speech

This study investigated talker-dependent and talker-independent perceptual adaptation to foreign-accent English. Experiment 1 investigated talker-dependent adaptation by comparing native English listeners' recognition accuracy for Chinese-accented English across single and multiple talker presentation conditions. Results showed that the native listeners adapted to the foreign-accented speech over the course of the single talker presentation condition with some variation in the rate and extent of this adaptation depending on the baseline sentence intelligibility of the foreign-accented talker. Experiment 2 investigated talker-independent perceptual adaptation to Chinese-accented English by exposing native English listeners to Chinese-accented English and then testing their perception of English produced by a novel Chinese-accented talker. Results showed that, if exposed to multiple talkers of Chinese-accented English during training, native English listeners could achieve talker-independent adaptation to Chinese-accented English. Taken together, these findings provide evidence for highly flexible speech perception processes that can adapt to speech that deviates substantially from the pronunciation norms in the native talker community along multiple acoustic-phonetic dimensions.     

Accommodating variation: dialects, idiolects, and speech processing

Listeners are faced with enormous variation in pronunciation, yet they rarely have difficulty understanding speech. Although much research has been devoted to figuring out how listeners deal with variability, virtually none (outside of sociolinguistics) has focused on the source of the variation itself. The current experiments explore whether different kinds of variation lead to different cognitive and behavioral adjustments. Specifically, we compare adjustments to the same acoustic consequence when it is due to context-independent variation (resulting from articulatory properties unique to a speaker) versus context-conditioned variation (resulting from common articulatory properties of speakers who share a dialect). The contrasting results for these two cases show that the source of a particular acoustic-phonetic variation affects how that variation is handled by the perceptual system. We also show that changes in perceptual representations do not necessarily lead to changes in production.     

Independent, synchronous access to color and motion features

We investigated the role of attention in pairing superimposed visual features. When moving dots alternate in color and in motion direction, reports of the perceived color and motion reveal an asynchrony: the most accurate reports occur when the motion change precedes the associated color change by approximately 100ms [Moutoussis, K., & Zeki, S. (1997). A direct demonstration of perceptual asynchrony in vision. Proceedings of the Royal Society of London B, 264, 393-399]. This feature binding asynchrony was probed by manipulating endogenous and exogenous attention. First, endogenous attention was manipulated by changing which feature dimension observers were instructed to attend to first. This yielded little effect on the asynchrony. Second, exogenous attention was manipulated by briefly presenting a ring around the target, cueing the report of the color and motion seen within the ring. This reduced or eliminated the apparent latency difference between color and motion. Accuracy was best predicted by timing of each feature relative to the cue rather than the timing of the two features relative to each other, suggesting independent attentional access to the two features with an exogenous attention cue. The timing of attentional cueing affected feature pairing reports as much as the timing of the features themselves.
