汉语隐喻理解时程的ERPs研究

摘 要 本研究使用ERPs技术考察隐喻句与本义句理解时程的异同,以研究汉语隐喻的理解机制。以句尾范式向被试随机呈现本义句、熟悉隐喻句、新奇隐喻句及错误义句各50句,被试的任务为判断每句话是否有意义。结果显示：两种隐喻句诱发的N400波形与头皮分布情况和本义句无明显差异,且两种隐喻句诱发的N400波幅高于本义句。本研究结果证明汉语隐喻义和本义理解的认知机制类似,支持隐喻理解的平行加工假说,且加工隐喻义需要耗费更多的认知资源。     

Developmental trends in auditory processing can provide early predictions of language acquisition in young infants

Auditory processing capabilities at the subcortical level have been hypothesized to impact an individual's development of both language and reading abilities. The present study examined whether auditory processing capabilities relate to language development in healthy 9‐month‐old infants. Participants were 71 infants (31 boys and 40 girls) with both Auditory Brainstem Response (ABR) and language assessments. At 6 weeks and/or 9 months of age, the infants underwent ABR testing using both a standard hearing screening protocol with 30 dB clicks and a second protocol using click pairs separated by 8, 16, and 64‐ms intervals presented at 80 dB. We evaluated the effects of interval duration on ABR latency and amplitude elicited by the second click. At 9 months, language development was assessed via parent report on the Chinese Communicative Development Inventory ‐ Putonghua version (CCDI‐P). Wave V latency z‐scores of the 64‐ms condition at 6 weeks showed strong direct relationships with Wave V latency in the same condition at 9 months. More importantly, shorter Wave V latencies at 9 months showed strong relationships with the CCDI‐P composite consisting of phrases understood, gestures, and words produced. Likewise, infants who had greater decreases in Wave V latencies from 6 weeks to 9 months had higher CCDI‐P composite scores. Females had higher language development scores and shorter Wave V latencies at both ages than males. Interestingly, when the ABR Wave V latencies at both ages were taken into account, the direct effects of gender on language disappeared. In conclusion, these results support the importance of low‐level auditory processing capabilities for early language acquisition in a population of typically developing young infants. Moreover, the auditory brainstem response in this paradigm shows promise as an electrophysiological marker to predict individual differences in language development in young children.     

Genetic and Environmental Influences on Adolescent Rumination and its Association with Depressive Symptoms

Rumination is an important cognitive vulnerability for adolescent and adult depression. However, little is known about the aetiological origins of rumination, as well as its association with depression. Adolescent rumination (self-report) and depressive symptoms (self- and parent-report) were assessed in 674 pairs of same-gender Chinese adolescent twins (11–17 years of age). Females accounted for 53.7 % of the sample. There were significant correlations between self-reported rumination and self-reported depression (r?=?0.41), as well as parent-reported adolescent depression (r?=?0.22). Genetic influences were significant and modest on all three measures, ranging from 24 % to 42 %. The three measures were also significantly influenced by shared environment, ranging from 20 % to 28 %, and non-shared environmental factors, ranging from 30 % to 56 %. Moreover, the genetic correlations between rumination and depression were significant (within-rater: r _g?=?0.99; cross-rater: r _g?=?0.59) and largely accounted for the phenotypic correlations (within-rater: 68 %; cross-rater: 77 %), while non-shared environmental correlations were also significant (within-rater: r _e?=?0.26; cross-rater: r _e?=?0.12) and accounted for the remainder of the phenotypic correlations (within-rater: 32 %; cross-rater: 23 %). The shared environmental correlations were non-significant. No significant gender and age differences were found in aetiological models. These findings suggest that rumination may be an endophenotype reflecting genetic risk for depression.     

新生代员工自杀意念的产生机理

新生代员工的自杀意念正在引起研究者的关注.本研究立足于职业健康心理学和积极心理学视野,汲取自我决定理论和生命意义理论的思想精髓以构建“动机-生命意义”模型,系统考察社会、组织和个体因素对自杀意念的综合影响,对揭示无精神疾患员工自杀意念产生的影响机制和心理动力机制、促进研究范式从病理取向转向积极取向具有重要的理论价值;此外,还有望开发出一套“社会-组织情境→动机→生命意义”干预方案,引导企业与政府反思其现有管理体系,帮助管理者审视其管理哲学并改善其管理行为,针对尚无自杀意念或意念处于萌芽期的员工,多层次、多途径构建员工自杀的一级防控体系和心理援助机制,促进员工与企业、社会的整体和谐发展.     

控制还是适应:次级控制研究的两种取向

次级控制是人在控制动机受威胁时的一种应对策略,它最初被定义为个体试图适应世界,顺应形势的过程.该概念在发展中被赋予了不同的解释,产生了所谓控制取向与适应取向的分歧.这两种取向在次级控制与首要控制的关系,次级控制与控制感的关系,以及次级控制的跨文化一致性问题上存在着分歧.近年来补偿性控制模型与健康领域的次级控制研究分别在概念上和功能上提供了整合两取向的可能性.未来研究应致力于进一步整合两取向的定义,扩展其研究的视野,并通过更多地使用实验法,来加强对其影响因素的研究.     

大学生压力事件与网络游戏成瘾:逃避动机的中介效应*

以472名男大学生网络游戏玩家为被试,考察了压力事件、网络游戏逃避动机和网络游戏成瘾的关系。结果发现:(1)大学生压力事件、网络游戏逃避动机和成瘾之间存在显著正相关。(2)压力事件除了对网络游戏成瘾有直接影响,还通过网络游戏逃避动机的中介作用对网络游戏成瘾产生间接影响。     

音乐训练对执行功能的影响

尽管音乐训练影响许多认知加工,但这种广泛性影响背后的机制迄今仍不清楚。近年来,研究者认为音乐训练的迁移效应可能是通过执行功能起作用。本文将执行功能细分为抑制控制、工作记忆、认知灵活性三个核心成分,考察音乐训练对这三个成分的影响以及执行功能在音乐训练迁移效应中的中介作用。研究结果表明,音乐训练对执行功能不同成分的影响有不同特点。同时,前额叶结构与功能的变化在音乐训练影响执行功能的过程中发挥着重要作用。此外,关于执行功能在音乐训练迁移效应中的中介作用,目前研究还存在不一致的结果,未来研究应采用多种技术手段深入探讨这一问题。     

The impact of smoking cues in antismoking messages among intermittent and light smokers

Objective: Based on the Limited Capacity Model of Motivated Mediated Message Processing, this study explored the effects of smoking cues in antismoking Public Service Announcements (PSAs) on message processing among intermittent/light smokers and nonsmokers.

Method: A 2 (smoking cues: present vs. absent) × 2 (smoking status: smokers vs. nonsmokers) mixed experimental design was conducted. Self-report measures and two physiological measures including skin conductance and heart rate were examined.

Results: Messages with smoking cues generated higher levels of arousal (F = 4.57, p = .04), attention (F = 2.51, p = .04), positive message evaluation (F = 28.70, p < .001) and less intent to smoke (F = 26.60, p < .001). Intermittent and light smokers had much stronger reactions to messages containing tobacco-related visuals, including arousal (F = 4.10, p = .04), perceived ad effectiveness (F = 9.24, p = .03) and intent to smoke (F = 22.98, p < .001).

Implication: The antismoking arguments may have suppressed cue-induced smoking urges, which dampened negative persuasion outcomes. Limitations included the restricted generalisability and the focus on short-term effect. Future research may use a random sample of PSAs with a general population.     

视觉长时记忆激活度对促进视觉短时记忆的影响

短时记忆与长时记忆的关系是记忆领域研究的重要内容。基于此, 研究者们就视觉长时记忆是否能促进视觉短时记忆的问题展开了大量研究, 但所得出的结论并不一致。通过不同程度的学习形成不同激活度的视觉长时记忆, 考察对几何图形的视觉长时记忆是否能对变化检测中的短时记忆起到促进作用。结果发现, 低激活水平的视觉长时记忆不能促进视觉短时记忆, 而事先存在且高度激活的视觉长时记忆对视觉短时记忆却具有促进作用; 同时, 随着视觉长时记忆激活水平的提高, 刺激间间隔的效应值也逐渐减小。本研究说明, 视觉长时记忆能否促进视觉短时记忆取决于视觉长时记忆的激活水平, 高激活的视觉长时记忆对阻止视觉短时记忆痕迹的迅速消退具有重要意义。     

Psychometric properties of the Padua Inventory in Chinese college samples

The aim of the present study was to investigate the psychometric properties of the Padua Inventory in Chinese college samples. Three different samples (N1 = 1,939, N2 = 1,341, and N3 = 298) of Chinese college students were recruited. Exploratory factor analyses yielded a four-factor structure which was similar to that found in previous studies. Further, present results showed good internal consistency as well as convergent and divergent validity with the subscales of the Symptom Checklist-90 and the Penn State Worry Questionnaire. Although no sex difference was found on total score, women had significantly higher scores on Factor 2 (Urges and worries of losing control over motor behaviors) and Factor 4 (Checking), while men had significantly higher scores on Factor 3 (Contamination). Implications of ter the results and directions for research are discussed.
