图形和汉字视觉认知任务中的部分线索效应

给被试呈现一幅图的不完整信息作为线索会干扰被试对图形的辨认,这是一种部分线索效应。实验一的任务是对模糊图形的辨认,在轮廓相似组图形中,部分线索的干扰作用随呈现模糊级次数的增加而更加显著,但在轮廓非相似组图形中,模糊级呈现次数为２次和３次的情况下,也表现出了显著的部分线索效应。实验二在不完整汉字识别任务中进一步考察了部分线索效应,在事先学习的条件下,形状相似字组汉字的辨认表现出了显著的部分线索效应,而意义相似字组和随机字组汉字的辨认表现出了部分线索的促进作用。在事先不学习的条件下,随机字组和形状相似字组汉字的辨认表现出了显著的部分线索效应,而意义相似字组汉字的辨认没有表现出显著的部分线索效应。本研究用激活的观点对这些结果做出了合理的解释。     

Social priming of hemispatial neglect affects spatial coding: Evidence from the Simon task

In the Simon effect (SE), choice reactions are fast if the location of the stimulus and the response correspond when stimulus location is task-irrelevant; therefore, the SE reflects the automatic processing of space. Priming of social concepts was found to affect automatic processing in the Stroop effect. We investigated whether spatial coding measured by the SE can be affected by the observer’s mental state. We used two social priming manipulations of impairments: one involving spatial processing - hemispatial neglect (HN) and another involving color perception - achromatopsia (ACHM). In two experiments the SE was reduced in the “neglected” visual field (VF) under the HN, but not under the ACHM manipulation. Our results show that spatial coding is sensitive to spatial representations that are not derived from task-relevant parameters, but from the observer’s cognitive state. These findings dispute stimulus-response interference models grounded on the idea of the automaticity of spatial processing.     

中文词汇加工中的饱和现象

长时间注视一个字或词语后,感觉这个字词变得奇怪且陌生,这种现象称为饱和现象。本研究采用快速类别/词汇匹配范式,考察中文词汇加工中的饱和现象。实验1-3发现单纯的语义或字形的重复均未能引发饱和,只有类别标签在字形和语义上的同时重复才引发饱和,表明与英文饱和相似,中文饱和发生在字形加工和语义加工的联结阶段。实验4结果表明,中文饱和还能够由表义部件的重复引发,体现了中文饱和的特殊性。

Rhythmic priming across effector systems: A randomized controlled trial with Parkinson’s disease patients

This study investigated the immediate effects of auditory-motor entrainment across effector systems by examining whether Rhythmic Auditory Stimulation training of arm or finger movements would modulate gait speed. Forty-one participants with idiopathic Parkinson’s Disease were randomly assigned to 3 groups. Participants in the finger-tapping group tapped in synchrony with a metronome set to 20% faster pace than the pre-training walking cadence, whereas participants in the other group were asked to swing both arms in an alternating motion in synchrony with the metronome. Participants in the control condition did not receive training. To assess gait parameters pre- and post-training, participants walked on a 14-meter flat walkway at his/her preferred walking cadence with no auditory cueing. Results indicated that there was a significant increase in gait velocity after the finger tapping training (p < .005), whereas no differences were observed in the arm swing (p = .802) and in the control conditions (p = .525). Similarly, there were significant changes in gait cadence post-training in the finger tapping group (p < .005), but not after arm swing training (p = .879) or control (p = .759). There were no significant changes in stride length post-training in none of the groups. These findings suggest that auditory-motor entrainment in one effector system may prime a second effector system. Interestingly, however, the priming effect on gait was only observed in the finger tapping condition and not with synchronized arm swing movements. These findings have significant implications for motor rehabilitation and open new avenues for further investigation of the mechanisms underlying cross-effector coupling.     

基于因果报应观念的认知调查与厚黑行为抑制效果分析

因果报应是中国传统文化的一个重要观念,至今仍然影响着当下社会大众。研究通过问卷调查来了解社会大众对因果报应的认知与理解,并进一步通过启动实验考察因果报应启动对厚黑行为的抑制效果,研究结果表明:(1)社会大众对因果报应的认知与接纳是一种客观存在,55.83%的被试知晓因果报应,33.81%的被试表示相信因果报应的存在,10.09%的被试表示因果报应很灵验,23.67%的被试表示因果报应影响自己的行为处世,22.96%的被试表示会用因果报应提示教育身边的亲友。(2)因果报应材料的启动能显著地抑制厚黑行为,中性材料的启动不能抑制厚黑行为,因果报应启动的内容与厚黑人格对厚黑行为具有交互效应,因果报应启动能更显著地抑制高厚黑人格被试的厚黑行为。基于社会治理的视角,社会公众对因果报应的接纳成就了其参与社会治理的可能性,因果报应内蕴的道德自律、匡扶正义、累德向善等价值内核成就了其参与社会治理的效用性,因果报应观念应建设性发掘和创造性地转化为当下的社会治理所用。     

Interactions of reading and semantics along the ventral visual processing stream

Converging evidence supports a distributed-plus-hub view of semantic processing, in which there are distributed modular semantic sub-systems (e.g., for shape, colour, and action) connected to an amodal semantic hub. Furthermore, object semantic processing of colour and shape, and lexical reading and identification, are processed mainly along the ventral stream, while action semantic processing occurs mainly along the dorsal stream. In Experiment 1, participants read a prime word that required imagining either the object or action referent, and then named a lexical word target. In Experiments 2 and 3, participants performed a lexical decision task (LDT) with the same targets as in Experiment 1, in the presence of foils that were legal nonwords (NW; Experiment 2) or pseudohomophones (PH; Experiment 3). Semantic priming was similar in effect size regardless of prime type for naming, but was greater for object primes than action primes for the LDT with PH foils, suggesting a shared-stream advantage when the task demands focus on orthographic lexical processing. These experiments extend the distributed-plus-hub model, and provide a novel paradigm for further research.     

Does religious priming increase the prosocial behaviour of a Japanese sample in an anonymous economic game?

We examined the effect of religious priming on a Japanese sample in an anonymous dictator game whereas previous studies on religious priming on prosociality had mainly been conducted within Western contexts. The current study attempted to examine whether religion increases prosocial behaviour in a Japanese sample through the replication of ‘God is Watching You’ (Shariff & Norenzayan, 2007) where it was found that participants primed with religion‐related words and secular justice‐related words behaved more prosocially than participants primed with neutral words in an anonymous dictator game. The current experiment was conducted with Japanese students (n = 106) to examine whether the results of the original study could be applied to Japanese people. The results showed that among the three priming conditions (control, religion, secular justice), there was no difference in the amount of money participants allocated to anonymous strangers, although in the secular justice priming condition, theists allocated more money than atheists. The results might be due to the fact that the religious priming words used in the original study did not precisely activate the propositional network of religion that Japanese participants have. More culture‐specific studies are necessary to examine how religious priming works for non‐Westerners.     

Does translation involve structural priming?

When asked to translate utterances, people might merely make sure that their translations have the same meaning as the source, but they might also maintain aspects of sentence form across languages. We report two experiments in which English–German and German–English bilinguals (without specialist translator training) repeated German ditransitive sentences whose meaning was compatible with more than one grammatical form or translated them into English. Participants almost invariably repeated the sentences accurately, thereby retaining the grammatical structure. Importantly, Experiment 1 found that they tended to repeat grammatical form across languages. Experiment 2 included a condition with sentences that had no grammatical equivalent form in English; here participants tended to persist in the order of thematic roles. We argue that cross-linguistic structural priming plays a major role in the act of translation.     

“Pushing the Button While Pushing the Argument”: Motor Priming of Abstract Action Language

In a behavioral study we analyzed the influence of visual action primes on abstract action sentence processing. We thereby aimed at investigating mental motor involvement during processes of meaning constitution of action verbs in abstract contexts. In the first experiment, participants executed either congruous or incongruous movements parallel to a video prime. In the second experiment, we added a no‐movement condition. After the execution of the movement, participants rendered a sensibility judgment on action sentence targets. It was expected that congruous movements would facilitate both concrete and abstract action sentence comprehension in comparison to the incongruous and the no‐movement condition. Results in Experiment 1 showed a concreteness effect but no effect of motor priming. Experiment 2 revealed a concreteness effect as well as an interaction effect of the sentence and the movement condition. The findings indicate an involvement of motor processes in abstract action language processing on a behavioral level.
