重金属镍胁迫对向日葵幼苗生理生化特性的影响 作者： 曾小飚 1 唐健民 2 朱成豪 2,3 邹蓉 2 史艳财 2 韦霄 2 蔡丽华 1 作者单位： 1. 百色学院，农业与食品工程学院，广西 百色 533000；广西壮族自治区中国科学院广西植物研究所，广西 桂林 541006；桂林医学院，广西 桂林 541004 提交时间： 2019-03-14 摘要: 试验以向日葵幼苗为试材，采用营养液培养法探索重金属镍胁迫对其生理生化指标的影响，揭示向日葵对镍胁迫的响应机制和幼苗生长发育的影响研究，为镍污染环境修复提供一定的科学依据。结果显示：低浓度的镍胁迫（≤10 mg•L-1）有利于幼苗的生长，高浓度的镍胁迫（≥50 mg•L-1）对幼苗具有明显的抑制作用。随着镍胁迫浓度逐渐增加，向日葵幼苗各项生理生化指标的变化较大，其中叶绿素、可溶性糖（SS）、可溶性蛋白（SP）、过氧化物酶（POD）活性、游离脯氨酸（Pro）的含量均在1~10 mg•L-1呈先上升趋势，50~100 mg•L-1呈下降的趋势；丙二醛（MDA）含量则呈现持续上升趋势。研究表明：向日葵幼苗对低浓度（1~10 mg•L-1）镍胁迫能通过自身调节，增加POD、Pro和MDA等物质的含量来提高对生态环境的抗逆能力，说明向日葵幼苗对重金属镍具有一定抗性，而高浓度（50~100 mg•L-1）镍胁迫会破坏其自身防御系统，影响幼苗的生长发育。 向日葵幼苗 镍胁迫 生长 生理生化特性 响应机制 分类： 生物学 >> 植物学 >> 应用植物学 引用： ChinaXiv:201903.00215 (或此版本 ChinaXiv:201903.00215V1 ) doi:10.12074/201903.00215 CSTR:32003.36.ChinaXiv.201903.00215.V1 推荐引用方式： 曾小飚,唐健民,朱成豪,邹蓉,史艳财,韦霄,蔡丽华.(2019).重金属镍胁迫对向日葵幼苗生理生化特性的影响.广西植物.[ChinaXiv:201903.00215] 版本历史 [V1] 2019-03-14 20:03:55 ChinaXiv:201903.00215V1 下载全文

歌词对音乐情绪加工的影响：行为与ERP研究 作者： 张伟霞 1 王莞琪 2 周临舒 3 蒋存梅 3 作者单位： 1. 上海师范大学教育学院 2. 上海师范大学商学院 3. 上海师范大学音乐学院, 上海 200234 提交时间： 2023-03-27 摘要: 本研究探讨了歌词对音乐情绪加工的影响。实验1使用情感启动范式, 带有歌词与无歌词音乐片段为启动刺激, 与音乐情绪一致或不一致的面孔图片为目标刺激, 被试任务是既快又准确地判断目标面孔的情绪。结果显示, 无论音乐是否带有歌词, 听者在一致条件下的反应都比不一致条件更快更准确, 这表明听者能加工音乐传达的情绪信息。实验2进一步通过电生理手段探讨歌词影响音乐情绪加工的神经机制。研究结果显示, 尽管听者对带有歌词和无歌词音乐情绪的加工都产生了启动效应, 但是无歌词音乐条件在250~450 ms时间窗口产生了N400效应, 而带有歌词音乐条件在500~700 ms时间窗口诱发了LPC效应, 该结果表明, 歌词影响了大脑加工音乐情绪的时间进程。本研究结果将在一定程度上为音乐与语言关系的探究提供依据。 Abstract: Music and language are unique to the human beings. It has been suggested that music and language have a common origin as an emotional protolanguage. The development of socialisation has resulted in the development of language into a symbolic communication system with explicit semantics. By contrast, music has become an important means of emotional expression. However, whether language with explicit semantics affects the emotional processing of music remains uncertain. Given that songs contain melody and lyrics, previous behavioural studies have focused on songs to analyse the influence of lyrics on the processing of musical emotion. However, several studies have also shown the influence of lyrics, although such findings are relatively contradictory.Thus, the current study used behavioural and electrophysiological measurements to investigate the impact of lyrics on the processing of musical emotion. Experiment 1 analysed whether the emotional connotations in music with and without lyrics could be perceived by listeners at the behavioural level. Experiment 2 further investigated whether there are different neural responses to emotions conveyed by melodies with and without lyrics.A cross-modal affective priming paradigm was used in Experiments 1 and 2, in which musical excerpts served as the prime and emotional faces as target. To avoid the impact of familiarity, 120 musical stimuli were selected from European opera. Each was sung by a vocalist with and without lyrics, thereby resulting in 240 musical stimuli in two versions as potential prime stimuli. A total of 160 facial expressions affectively congruent or incongruent with the preceding musical stimuli were selected as potential target stimuli. Three pre-tests were conducted to ensure the validity of the stimuli. Eventually, 60 musical stimuli for each music version were selected as the prime stimuli, whilst 120 images were used as the target stimuli, thereby resulting in 240 music-image pairs. To ensure that each stimulus appears only once for each participant, two lists were prepared using a Latin square design. Each prime and target was presented in either the congruent or incongruent condition within each list. Thus, each list comprised 120 trials, with 30 trials in each condition. During the experiment, the two lists were equally distributed across the participants. A total of 40 healthy adults participated in Experiment 1. They were asked to judge as quickly and accurately as possible whether the emotion of the target was happy or sad. The accuracy and reaction time were collected. Meanwhile, 20 healthy adults participated in Experiment 2. They were required to judge whether the emotion between music and image was congruent or incongruent whilst their EEG waveforms were recorded. ERPs were analysed and compared between conditions at the time windows of 250~450 ms and 500~700 ms after the onset of the target.The Experiment 1 results showed that when faces were primed by music either with or without lyrics, the participants responded faster and more accurately under affectively congruent condition compared with affectively incongruent condition. This finding indicated that the emotional connotations in music with and without lyrics could both be perceived. The ERP results in Experiment 2 showed that distinct neural mechanisms were activated by music with and without lyrics. Specifically, when faces were primed by music without lyrics, a larger N400 was elicited in response to affectively incongruent pairs than to affectively congruent pairs at the time window of 250~450 ms. However, when faces were primed by music with lyrics, a more positive LPC was observed in response to the affectively incongruent pairs than to the affectively congruent pairs at 500~700 ms. This finding confirms the results of Experiment 1, thereby suggesting that the emotion conveyed by music with and without lyrics could be perceived by the listeners. Moreover, the emotional processing between music with and without lyrics differs in the time course of neural processing. That is, the emotional processing of music with lyrics lagged behind that of music without lyrics.In conclusion, the present results suggest that the neural processing of emotional connotations in music without lyrics preceded that of music with lyrics, although the emotional connotations conveyed by music with and without lyrics could both be perceived. These findings also supported theory of musical philosophy, which suggests that music without lyrics can express emotion more immediately and more directly than music with lyrics owing to the lack of “translation” from the propositional system. On the other hand, considering that lyrics influenced the time course of emotional processing in music with lyrics, our results also provide evidence that the emotional processing of music and language may share neural resources to some extent. 音乐情绪 语言 歌词 N400 LPC 期刊： 心理学报 分类： 心理学 >> 社会心理学 引用： ChinaXiv:202303.08577 (或此版本 ChinaXiv:202303.08577V1 ) DOI:10.3724/SP.J.1041.2018.01346 CSTR:32003.36.ChinaXiv.202303.08577.V1 推荐引用方式： 张伟霞,王莞琪,周临舒,蒋存梅.(2023).歌词对音乐情绪加工的影响：行为与ERP研究.心理学报.doi:10.3724/SP.J.1041.2018.01346 版本历史 [V1] 2023-03-27 16:00:26 ChinaXiv:202303.08577V1 下载全文
