Cerebral blood flow in 5‐ to 8‐month‐olds: Regional tissue maturity is associated with infant affect
M. Catalina Camacho Lucy S. King Amar Ojha Cheyenne M. Garcia Lucinda M. Sisk Anna C. Cichocki Kathryn L. Humphreys Ian H. Gotlib 《Developmental science》2020,23(5)
Infancy is marked by rapid neural and emotional development. The relation between brain function and emotion in infancy, however, is not well understood. Methods for measuring brain function predominantly rely on the BOLD signal; however, interpretation of the BOLD signal in infancy is challenging because the neuronal‐hemodynamic relation is immature. Regional cerebral blood flow (rCBF) provides a context for the infant BOLD signal and can yield insight into the developmental maturity of brain regions that may support affective behaviors. This study aims to elucidate the relations among rCBF, age, and emotion in infancy. One hundred and seven mothers reported their infants' (infant age M ± SD = 6.14 ± 0.51 months) temperament. A subsample of infants completed MRI scans, 38 of whom produced usable perfusion MRI during natural sleep to quantify rCBF. Mother‐infant dyads completed the repeated Still‐Face Paradigm, from which infant affect reactivity and recovery to stress were quantified. We tested associations of infant age at scan, temperament factor scores, and observed affect reactivity and recovery with voxel‐wise rCBF. Infant age was positively associated with CBF in nearly all voxels, with peaks located in sensory cortices and the ventral prefrontal cortex, supporting the formulation that rCBF is an indicator of tissue maturity. Temperamental Negative Affect and recovery of positive affect following a stressor were positively associated with rCBF in several cortical and subcortical limbic regions, including the orbitofrontal cortex and inferior frontal gyrus. This finding yields insight into the nature of affective neurodevelopment during infancy. Specifically, infants with relatively increased prefrontal cortex maturity may evidence a disposition toward greater negative affect and negative reactivity in their daily lives yet show better recovery of positive affect following a social stressor. 相似文献

面孔认知研究表明, 人们识别和再认自己所属群体(如种族、性别、年龄)面孔的成绩显著好于识别其他群体面孔的成绩。近年来围绕面孔识别的这种自我群体偏向进行了实验研究, 研究者提出了知觉经验说和社会认知论两种理论来解释其认知加工机制, 而类别化-个性化模型和双路径模型则是将两种理论分别加以整合提出的新解释。研究者还对面孔识别自我群体偏向的神经机制进行了研究, 探讨了评价者、评价对象和评价任务等因素对自我群体偏向的影响。提升面孔识别自我群体偏向研究的生态效度, 构建整合性理论模型以及加强跨文化和本土研究是未来研究的重要方向。 相似文献

包装上的元素信息是消费者感知环境刺激的重要来源, 能对消费者决策产生重要影响。包装元素可分为非语言型包装元素和语言型包装元素两类, 它们对消费者有不同的影响。总体而言, 非语言型包装元素主要影响消费者的感知和情感偏好, 而语言型包装元素更多影响消费者的行为倾向和行为结果。同时, 两类包装元素对消费者产生影响的内在机制可从神经生理机制、认知加工机制、自我控制的转移和多感官交互几方面进行讨论。此外, 两类包装元素对消费者的影响还会受到环境特征、产品特征以及消费者个体特征的调节。未来研究可进一步探讨两类包装元素对消费者尴尬情绪、透明包装的选择以及产品评价等结果的影响。 相似文献

采用跨通道启动范式,探讨言语与面孔情绪加工的相互影响效应,以及语言差异(母语:汉语;非母语:英语)在其中的影响作用。实验1以言语情绪词为启动刺激,面孔情绪为目标刺激,结果发现,相比于英语启动刺激条件,在汉语启动刺激条件下的面孔情绪判断具有更好的表现;在积极情绪启动条件下,言语情绪刺激能够启动面孔情绪刺激。实验2以面孔情绪为启动刺激,言语情绪词为目标刺激,结果发现,相比于英语目标刺激条件,在汉语目标刺激条件下的言语情绪判断具有更好的表现;在积极情绪启动条件下,面孔情绪刺激能够启动言语情绪刺激。研究结果表明,言语情绪与面孔情绪的加工能够相互影响,但这种相互关系仅表现在积极情绪启动条件下。此外,母语和非母语在情绪功能上具有差异性。 相似文献

The automatic evaluation of novel stimuli 总被引:6,自引:0,他引:6
From classic theory and research in psychology, we distill a broad theoretical statement that evaluative responding can be immediate, unintentional, implicit, stimulus based, and linked directly to approach and avoidance motives. This statement suggests that evaluative responses should be elicited by novel, nonrepresentational stimuli (e.g., abstract art, "foreign" words). We tested this hypothesis through combining the best features of relevant automatic–affect research paradigms. We first obtained explicit evaluative ratings of novel stimuli. From these, we selected normatively positive and negative stimuli to use as primes in a sequential priming paradigm. Two experiments using this paradigm demonstrated that briefly presented novel prime stimuli were evaluated automatically, as they facilitated responses to subsequently presented target stimuli of the same valence just as much as did pictures or names of real objects. A final experiment revealed that exposure to novel stimuli produces muscular predispositions to approach or avoid them. 相似文献

The authors extend recent research concerning the social costs of claiming discrimination by examining men's and women's responses to in-group and out-group targets who either blamed a failing grade on discrimination or answer quality. Although participants generally responded more negatively to targets who blamed discrimination, rather than answer quality, dislike was greatest and gender group identification was lowest when participants evaluated an in-group target. Moreover, an in-group target who claimed discrimination was perceived as avoiding personal responsibility for outcomes to a greater extent than was a similar out-group target. Perceptions that the target avoided outcome responsibility by claiming discrimination were shown to mediate the relationship between attribution type and dislike of the in-group target. The authors discuss their results in terms of intragroup processes and suggest that social costs may especially accrue for in-group members when claiming discrimination has implications for the in-group's social identity. 相似文献

通过对8名11~14岁初中生的深入访谈,初步探讨了处于初中阶段的青少年认同的亲社会行为。发现:(1)初中生最认同的亲社会行为是帮助行为,其次是交往行为。此外,安慰行为、公益行为、礼貌行为和遵规行为也被他们认同;(2)初中生对不同行为主体间发生的亲社会行为的认同有明显差异,他们更关心发生在他们之间的亲社会行为;(3)普通学校、打工子弟学校的初中生对帮助行为和交往行为认同的比率差异明显;(4)初中生认同的亲社会行为的种类不存在明显的性别差异。 相似文献
