简单暴露效应的理论模型

简单暴露效应（MereExposureEffect,MEE）的概念最初由Zajonc提出,指的是刺激的简单暴露能够成为提高个体态度的充分条件。文章在简要回顾简单暴露效应概念、影响因素以及表现类型的基础之上,重点介绍了解释简单暴露效应产生机制的理论模型,并探讨了理论构建中存在的一些问题     

Infants’ expressive behaviors to mothers and unfamiliar partners during face-to-face interactions from 4 to 10 months

Changes in the organization of infant looking, facial expressions, and vocalizations were examined over age (4, 7, and 10 months) and with different social partners. Although infants at all ages accompanied smiling with looking at both mothers and unfamiliar partners, 7- and 10-month infants accompanied vocalization with looking only when they were with mothers. Seven- and 10-month-olds vocalized with unfamiliar partners only when they were smiling at the same time. When mothers stopped talking, infants reduced smiling significantly at all ages, yet vocalized more at 10 months. In the second half of the first year, there are fundamental changes in the coordination of infant expressive behaviors that reveal a keen attunement to variations in maternal behavior and the familiarity of social partners.     

Young children's affective decision-making in a gambling task: Does difficulty in learning the gain/loss schedule matter?

This research investigated the development of affective decision-making (ADM) during early childhood, in particular role of difficulty in learning a gain/loss schedule. In Experiment 1, we administrated the Children's Gambling Task (CGT) to 60 Chinese children aged 3 and 4, replicating the results obtained by Kerr and Zelazo [Kerr, A., & Zelazo, P. D. (2004). Development of “hot” executive function: The Children's Gambling Task. Brain and Cognition, 55, 148–157]. In Experiment 2, the CGT was modified to make it easier for young children to learn the gain/loss schedule by increasing delayed loss frequency and magnitude in the disadvantageous deck, and a larger sample (181 children aged 3–5) was assessed. Age-differences between 3- and 4-year-olds, rather than 4- and 5-year-olds, showed that ADM develops rapidly between 3 and 4 years. The reduction of the difficulty in learning the gain/loss schedule provides the basis for an account of the development of young children's AMD.     

Vocal Features of Conversational Sarcasm: A Comparison of Methods

This study investigated vocal cues that differentiate sarcastic utterances from non-sarcastic utterances. Utterances were drawn from videotapes of participant interviews and arranged on a master tape for analysis. Utterances that were identified as sarcastic by speakers and recognized as sarcastic by listeners were randomly arranged with utterances identified and recognized as non-sarcastic by the same participants. Both sarcastic and non-sarcastic utterances were analyzed by two methods–acoustic analysis and perceptual coding. The acoustic analysis proved slightly more successful than the perceptual coding in discriminating between sarcastic and non-sarcastic utterances. The acoustic analysis indicated that fundamental frequency, frequency range, length of utterance, and total amount of sound significantly discriminated sarcastic from non-sarcastic utterances. The perceptual coding method revealed that pitch range, length of utterance, and total amount of sound significantly discriminated sarcastic from non-sarcastic utterances. Moderate correlations were found between the acoustic and perceptual variables.     

Own-other differences in the realism of some metacognitive judgments

The present study investigated differences in judgments of one's own and others' knowledge (the own-other difference). Consistent with the below-average effect (e.g., Kruger, 1999), our main results showed that the participants gave lower knowledge ratings of their own extent of knowledge than of another person's extent of knowledge (Experiment 1). Furthermore, lower and more realistic judgments were found when the participants judged their own as compared with when judging another person's overall accuracy (frequency judgments) of answering knowledge questions correctly (Experiment 1 and 2). On the basis of these results it is argued that judgmental anchoring may be important also in the context of indirect comparisons, and that previous conclusions of cross-cultural psychology regarding the above-average effect may be oversimplified.     

The molarity of molecular theory and the molecularity of molar theory.

Dinsmoor (2001) rejects shock-frequency reduction as a reinforcer for avoidance behavior, and considers this to be an invalidation of so-called molar avoidance theory. This is a narrow view of operant avoidance theory, for which shock-frequency reduction is by no means the only reinforcer.     

广告频率和品牌成熟度对信息加工模式的影响

广告可以通过受众的自动化加工和控制性加工两条途径为品牌价值的建立作出贡献。该研究运用加工分离程序,探讨了在不同的呈现频率下,受众对不同成熟度商品的广告的信息加工模式。结果发现：(1)在非注意条件下,与新品牌相比,成熟品牌会引起更多的自动化加工,控制性加工在各种成熟度的商品之间差异不显著;(2)在低卷入学习状态下,重复既提高了广告的自动影响,也提高了控制性加工的影响。因此,重复播放是提高广告有效性的一条途径。     

汉语音节累积词频对同音字听觉词汇表征的激活作用

汉语同音字音节的累积词频是同音单字词的具体词频之和, 即音节作为词被听到的频数, 也称为音节词频。它对词汇通达的作用还没获得一致看法。本文探讨听觉词汇通达中同音字表征的激活如何受累积词频的影响, 构成累积词频的具体词频和同音字数又会在其中起何作用。研究采用跨通道的音-字同音判断范式和配套的协方差分析分离出听觉的词汇表征激活作用。实验1固定同音字数, 同时变化累积词频和具体词频(其中具体高、低频同时也是同音字族内的高、低频), 结果发现具体词频的提高对表征激活有积极作用; 累积词频的提高仅在错误率上产生微弱的抑制作用, 而这个微弱作用可以归结为同音字族内高频字表征的激活对低频字表征的抑制。实验2固定具体词频, 同时变化累积词频和同音字数, 结果发现同音字数增加对表征激活产生抑制, 没有发现累积词频的作用。两个实验的结果说明, 音节累积词频对同音字的听觉词汇表征激活不起确定作用, 能够起作用的是同音字族内的具体词频和同音字数; 但同音字数变化的抑制作用仅在具体词频不变时才发生, 因此起决定作用的是同音字族内高频字表征激活和低频字表征抑制的机制。     

图片命名中词汇频率效应的眼动研究

在延时命名范式的基础上,通过控制熟悉性并运用连续图片命名的眼动记录技术,考察图片的注视时间,将词汇提取的过程单独地呈现出来。实验结果表明,在控制熟悉性及延时命名的条件下,图片名称的频率仍影响着图片的注视时间,表现出频率效应,但对出声输出的快慢没有影响,从而进一步证实了图片命名频率效应的“词汇通达假设”。     

The role of vowel formant frequencies and duration in the perception of foreign accent

ABSTRACT

This study used synthesis to manipulate vowel formant frequencies and durations to evaluate their role on foreign accent perception. Formant frequencies and durations for the vowels /æ/, /?/, and /a/ were manipulated with changes toward and away from the mean native English and Spanish-accented values from Sidaras, S. K., Alexander, J. E. D., & Nygaard, L. C. (2009. Perceptual learning of systematic variation in Spanish-accented speech. The Journal of the Acoustical Society of America, 125, 3306–3316). Native listeners rated these stimuli on degree of accentedness and comprehensibility. Gradual changes in formant frequencies from native to non-native values impacted /a/ negatively, /?/ positively, and /æ/ minimally. Effects of vowel duration on either type of ratings were small and restricted to vowel-specific interactions. The current findings suggest that vowel formant frequencies are primary cues to foreign accent. Their influence depends upon whether or not frequencies could reflect alternative vowel categories.
