The embodiment of beauty: Evidence from viewing Chinese concrete words and pictographs

How is beauty embodied? According to the viewpoint of embodied cognition, the aesthetic processing of words or pictographs has roots in their referential archetypes. Four experiments tested whether the beauty of referential archetypes was routinely activated during the explicit and implicit aesthetic evaluations of the font structures of concrete Chinese words and pictographs in congruent or incongruent font colour. Results showed font structures of simplified Chinese words and pictographs were judged to be more beautiful when they referred to beautiful archetypes; and this pattern was reversed when they referred to ugly archetypes. Moreover, judgement was facilitated when font colour was congruent for Chinese words and pictographs referred to beautiful archetypes. For those referred to ugly archetypes, judgement was inhibited in congruent font colour but facilitated in incongruent font colour, suggesting aesthetic perceptions of the font structures of Chinese words and pictographs were derived from their referential natural objects. The spontaneous generation hypothesis of beauty is proposed to account for these findings.     

The differentiation of response numerosities in the pigeon

Two experiments examined how pigeons differentiate response patterns along the dimension of number. In Experiment 1, 5 pigeons received food after pecking the left key at least N times and then switching to the right key (Mechner's Fixed Consecutive Number schedule). Parameter N varied across conditions from 4 to 32. Results showed that run length on the left key followed a normal distribution whose mean and standard deviation increased linearly with N; the coefficient of variation approached a constant value (the scalar property). In Experiment 2, 4 pigeons received food with probability p for pecking the left key exactly four times and then switching. If that did not happen, the pigeons still could receive food by returning to the left key and pecking it for a total of at least 16 times and then switching. Parameter p varied across conditions from 1.0 to .25. Results showed that when p= 1.0 or p=.5, pigeons learned two response numerosities within the same condition. When p=.25, each pigeon adapted to the schedule differently. Two of them emitted first runs well described by a mixture of two normal distributions, one with mean close to 4 and the other with mean close to 16 pecks. A mathematical model for the differentiation of response numerosity in Fixed Consecutive Number schedules is proposed.     

语言理解的体验观

随着体验哲学和体验认知的蓬勃发展,在语言理解中出现了强调经验作用的新观点,这就是语言理解的体验观。其基本观点是语言根植于知觉和运动,语言理解就是对语言所描述的情境建构心理模拟。这种模拟是以理解者的身体的、情绪的和社会的经验为基础的,因此语言理解实质上是对语言所指代的情境的心理上的经验重演。在语言理解的体验观中,索引假设、浸入式经历者框架和语言的神经理论具有一定的代表性     

具身认知:认知心理学的新取向

具身认知强调身体在认知的实现中发挥着关键作用。其中心含义包括:(1)认知过程的进行方式和步骤实际上是被身体的物理属性所决定的;(2)认知的内容是身体提供的;(3)认知、身体、环境是一体的,认知存在于大脑,大脑存在于身体,身体存在于环境。具身认知最初仅仅是一种哲学思考,有深刻的哲学思想渊源,但是现在这种哲学思考已经开始走向实证领域,实验的认知心理学家开始从具身的角度看待认知,形成了具身认知研究思潮。但是具身认知研究也面临着许多亟待解决的问题。     

Tactile Enumeration and Embodied Numerosity Among the Deaf

Representations of the fingers are embodied in our cognition and influence performance in enumeration tasks. Among deaf signers, the fingers also serve as a tool for communication in sign language. Previous studies in normal hearing (NH) participants showed effects of embodiment (i.e., embodied numerosity) on tactile enumeration using the fingers of one hand. In this research, we examined the influence of extensive visuo-manual use on tactile enumeration among the deaf. We carried out four enumeration task experiments, using 1–5 stimuli, on a profoundly deaf group (n = 16) and a matching NH group (n = 15): (a) tactile enumeration using one hand, (b) tactile enumeration using two hands, (c) visual enumeration of finger signs, and (d) visual enumeration of dots. In the tactile tasks, we found salient embodied effects in the deaf group compared to the NH group. In the visual enumeration of finger signs task, we controlled the meanings of the stimuli presentation type (e.g., finger-counting habit, fingerspelled letters, both or neither). Interestingly, when comparing fingerspelled letters to neutrals (i.e., not letters or numerical finger-counting signs), an inhibition pattern was observed among the deaf. The findings uncover the influence of rich visuo-manual experiences and language on embodied representations. In addition, we propose that these influences can partially account for the lag in mathematical competencies in the deaf compared to NH peers. Lastly, we further discuss how our findings support a contemporary model for mental numerical representations and finger-counting habits.

从知觉符号理论出发对情绪启动效应进行解读,启动刺激与目标刺激涉及的知觉符号相似性、框架相似性及模态激活延续性是情绪启动效应产生的可能机制和影响因素。在此基础上总结归纳出情绪启动的知觉符号匹配假说,并建构情绪启动效应认知加工模型,对现有情绪启动理论进行整合和拓展,以促进情绪启动刺激材料的拓展、提高研究生态效度; 促进情绪启动效应操作的有效性,进而提高其应用价值。情绪启动研究亦能反哺于知觉符号理论,促进其发展。     

Numerosity discrimination in deep neural networks: Initial competence,developmental refinement and experience statistics

Both humans and non‐human animals exhibit sensitivity to the approximate number of items in a visual array, as indexed by their performance in numerosity discrimination tasks, and even neonates can detect changes in numerosity. These findings are often interpreted as evidence for an innate ‘number sense’. However, recent simulation work has challenged this view by showing that human‐like sensitivity to numerosity can emerge in deep neural networks that build an internal model of the sensory data. This emergentist perspective posits a central role for experience in shaping our number sense and might explain why numerical acuity progressively increases over the course of development. Here we substantiate this hypothesis by introducing a progressive unsupervised deep learning algorithm, which allows us to model the development of numerical acuity through experience. We also investigate how the statistical distribution of numerical and non‐numerical features in natural environments affects the emergence of numerosity representations in the computational model. Our simulations show that deep networks can exhibit numerosity sensitivity prior to any training, as well as a progressive developmental refinement that is modulated by the statistical structure of the learning environment. To validate our simulations, we offer a refinement to the quantitative characterization of the developmental patterns observed in human children. Overall, our findings suggest that it may not be necessary to assume that animals are endowed with a dedicated system for processing numerosity, since domain‐general learning mechanisms can capture key characteristics others have attributed to an evolutionarily specialized number system.     

具身认知视角下语义理解中的身体角色:以研究方法为线索

具身认知认为,概念形成和语言理解等高级心理过程本质上是以感知觉和运动经验为基础的。神经影像学研究发现,理解身体动作词激活了支配该部分肢体的感觉运动脑区。理解手部、脚部和面部动作词能够相应激活支配手部、脚部和面部的感觉运动脑区,体现出一种身体动作词语义理解激活的脑区与真实身体动作激活脑区的耦合效应。临床和经颅磁刺激研究结果表明,感觉运动皮层的激活与身体动作词语义处理具有因果性作用。未来研究应关注身体动作词语义理解的具身程度以及相关语言疗法在临床患者机能恢复中所起的作用。     

具身记忆及其内在机制

具身记忆研究主要探讨身体及其感觉运动过程在记忆中的作用。操纵或限制身体的物理状态、具身特征或可用性,可以影响记忆的效率、效价和内容。其内在机制可以通过编码特异性原理、启动效应、隐喻表征理论和再激活假说进行解释,但尚未形成统一的模型。基于现有研究与理论的共性,提出具身记忆的感觉运动模拟模型,强调重新激活在具身记忆中的作用,以期在同一框架下说明身体作用于记忆的过程,并进一步指出重新激活的条件。未来亟需在具身记忆的稳定性以及深层机制等方面进行多维度的基础和应用研究。     

货币幻觉的心理机制与影响因素

货币幻觉是指经济交易活动中,人们因倾向于以货币的名义价值而非实际价值思考而对其消费和投资行为造成影响的一种认知偏差。大量研究表明,货币幻觉普遍存在于房地产投资、股票投资、组织管理以及捐赠等领域中。目前,研究者主要从决策框架、锚定与调整启发式、数目启发式以及神经心理机制这四个方面解释货币幻觉的形成机制。研究发现,货币幻觉的影响因素有心境、货币兑换率、通货膨胀率、情感依恋和先前经验。未来的研究可以从深入探讨货币幻觉的心理机制、影响因素和探索货币幻觉的应对策略这三个方面展开。
