On the predictive validity of various corpus-based frequency norms in L2 English lexical processing

The predictive validity of various corpus-based frequency norms in first-language lexical processing has been intensively investigated in previous research, but less attention has been paid to this issue in second-language (L2) processing. To bridge the gap, in the present study we took English as a case in point and compared the predictive power of a large set of corpus-based frequency norms for the performance of an L2 English visual lexical decision task (LDT). Our results showed that, in general, the frequency norms from SUBTLEX-US and WorldLex–Blog tended to predict L2 performance better in reaction times, whereas the frequency norms from corpora with a mixture of written and spoken genres (CELEX, WorldLex–Blog, BNC, ANC, and COCA) tended to predict L2 accuracy better. Although replicated in both low- and high-proficiency L2 English learners, these patterns were not exactly the same as those found in LDT data from native English speakers. In addition, we only observed some limited advantages of the lemma frequency and contextual diversity measures over the wordform frequency measure in predicting L2 lexical processing. The results of the present study, especially the detailed comparisons among the different corpora, provide methodological implications for future L2 lexical research.     

How honest are the signals? A protocol for validating wearable sensors

There is growing interest among organizational researchers in tapping into alternative sources of data beyond self-reports to provide a new avenue for measuring behavioral constructs. Use of alternative data sources such as wearable sensors is necessary for developing theory and enhancing organizational practice. Although wearable sensors are now commercially available, the veracity of the data they capture is largely unknown and mostly based on manufacturers’ claims. The goal of this research is to test the validity and reliability of data captured by one such wearable badge (by Humanyze) in the context of structured meetings where all individuals wear a badge for the duration of the encounter. We developed a series of studies, each targeting a specific sensor of this badge that is relevant for structured meetings, and we make specific recommendations for badge data usage based on our validation results. We have incorporated the insights from our studies on a website that researchers can use to conduct validation tests for their badges, upload their data, and assess the validity of the data. We discuss this website in the corresponding studies.     

资源多寡对大学生择偶线索偏好的影响

本研究采用分配择偶币的范式考察资源多寡对大学生择偶线索偏好的影响。结果发现：1）择偶资源多寡影响大学生的择偶线索偏好,低资源条件下人们更看重忠贞、健康等“必需品”（necessities）,高资源条件下则会增加对创造力等“奢侈品”（luxuries）的考虑。2）择偶线索偏好存在性别差异,当自身资源较少时,女性比男性更看重长期伴侣的社会经济地位,而男性比女性更看重伴侣的忠贞;当自身具备高资源时,性别差异不显著。本研究发现择偶线索中的“奢侈品”和国外研究结果类似,而“必需品”和国外研究差异较大。研究结果表明,择偶线索偏好可能受到进化和社会文化因素的共同影响。     

Emotionally conditioning the target-speech voice enhances recognition of the target speech under “cocktail-party” listening conditions

Under a noisy “cocktail-party” listening condition with multiple people talking, listeners can use various perceptual/cognitive unmasking cues to improve recognition of the target speech against informational speech-on-speech masking. One potential unmasking cue is the emotion expressed in a speech voice, by means of certain acoustical features. However, it was unclear whether emotionally conditioning a target-speech voice that has none of the typical acoustical features of emotions (i.e., an emotionally neutral voice) can be used by listeners for enhancing target-speech recognition under speech-on-speech masking conditions. In this study we examined the recognition of target speech against a two-talker speech masker both before and after the emotionally neutral target voice was paired with a loud female screaming sound that has a marked negative emotional valence. The results showed that recognition of the target speech (especially the first keyword in a target sentence) was significantly improved by emotionally conditioning the target speaker’s voice. Moreover, the emotional unmasking effect was independent of the unmasking effect of the perceived spatial separation between the target speech and the masker. Also, (skin conductance) electrodermal responses became stronger after emotional learning when the target speech and masker were perceptually co-located, suggesting an increase of listening efforts when the target speech was informationally masked. These results indicate that emotionally conditioning the target speaker’s voice does not change the acoustical parameters of the target-speech stimuli, but the emotionally conditioned vocal features can be used as cues for unmasking target speech.     

“在场的”科学主体及其认知模式

传统上对科学的看法常常因为主体与客体绝对的二元对立而陷入困境,这个困境使得科学的真理观要么滑向客观主义的绝对主义,要么滑向主观主义的相对主义;这两种立场都没有恰当地反映出主体在科学实践中的恰当地位和作用。我们将以上述方式所看待的主体称为不在场的(non-present)     

政府审计维护国家经济安全的体制寻优与机制构建

政府审计维护国家经济安全理论和实践的探索已多年,但对其体制和机制的研究尚未有突破进展.本文对中国政府审计体制展开剖析,认为现行体制在维护国家经济安全方面颇具优势,更能彰显政府审计批判性、建设性、宏观性、服务性和开放性的特征,故应发展而不是舍弃现行体制.在此体制轮廓下,本文论述了政府审计维护国家经济安全的机制设计与构建,阐述了明确行为依据、认知活动领域、优化作用方式、厘清运行路线、强化素质与管理保障五方面的构建内容与实施路径.     

医患沟通的三层"修炼"

良好的医患沟通能力可以避免或大大减少医疗纠纷的发生.医患沟通能力的提高需要不断地思考与实践.医患沟通需要经历三个阶段:技术沟通是指基础性的沟通内容及方式方法,用"心"沟通是指带着热忱、设身处地与无微不至的关怀与患者沟通,"忘记"沟通是指发自内心的、自然而然的沟通,才能达到高水平的沟通.     

怀旧与怀古:从心理到文化

无论是怀旧还是怀古,我们都不陌生。即使一个人对之没有深刻的体会,也可能从古今众多的文学作品尤其是诗歌中,领略过相关的情怀。不过,人们熟悉的现象,只能说明它具有普遍性,并不意味着我们真正理解它。依哲学的观点,只有通过深入的反思,才能揭示这些意识活动的深层意义。本文的努力,是把怀旧与怀古当作一种心理-文化的关联现象来理解。依次论述     

学前儿童情绪理解的发展及其与父母元情绪理念的关系

通过对341名3～5岁儿童情绪理解的测查及问卷调查,考察儿童情绪理解的发展特点及其与父母元情绪理念的关系。结果表明:(1)女孩的情绪识别显著优于男孩;(2)学前儿童的情绪理解具有显著的年龄差异,年长儿童显著优于年幼儿童;(3)母亲情绪不干涉的元情绪理念对儿童情绪识别具有促进作用,而情绪紊乱的理念则对儿童情绪识别有阻碍作用;(4)与日常经验不同,父亲情绪紊乱的元情绪理念可能反而对儿童情绪识别、情景情绪理解具有正向作用。
