The Word Superiority Effect in central and peripheral vision

The Word Superiority Effect (WSE) is a well-known phenomenon in reading research, where words are reported more accurately than single letters or non-words. We report two experiments that investigate the WSE in the central and peripheral visual field, as well as laterality differences in the perception of words and letters, using methods based on the Theory of Visual Attention. The results show a WSE in the central visual field, reflected in mean scores, perception thresholds, and processing speed, whereas the effect is eliminated or reversed in the periphery. This may be caused by crowding, which prevents lexical analysis of a word in the periphery. We conclude that perception of words and letters differs according to location in the visual field. Linking our results to previous studies of crowding effects in patients with reading impairments, we hypothesize that similar mechanisms may limit normal word peripheral processing.     

Selective scanpath repetition during memory-guided visual search

Visual search efficiency improves with repetition of a search display, yet the mechanisms behind these processing gains remain unclear. According to Scanpath Theory, memory retrieval is mediated by repetition of the pattern of eye movements or “scanpath” elicited during stimulus encoding. Using this framework, we tested the prediction that scanpath recapitulation reflects relational memory guidance during repeated search events. Younger and older subjects were instructed to find changing targets within flickering naturalistic scenes. Search efficiency (search time, number of fixations, fixation duration) and scanpath similarity (repetition) were compared across age groups for novel (V1) and repeated (V2) search events. Younger adults outperformed older adults on all efficiency measures at both V1 and V2, while the search time benefit for repeated viewing (V1–V2) did not differ by age. Fixation-binned scanpath similarity analyses revealed repetition of initial and final (but not middle) V1 fixations at V2, with older adults repeating more initial V1 fixations than young adults. In young adults only, early scanpath similarity correlated negatively with search time at test, indicating increased efficiency, whereas the similarity of V2 fixations to middle V1 fixations predicted poor search performance. We conclude that scanpath compression mediates increased search efficiency by selectively recapitulating encoding fixations that provide goal-relevant input. Extending Scanpath Theory, results suggest that scanpath repetition varies as a function of time and memory integrity.     

A stimulus set of words and pictures matched for visual and semantic similarity

Researchers in different fields of psychology have been interested in how vision and language interact, and what type of representations are involved in such interactions. We introduce a stimulus set that facilitates such research (available online). The set consists of 100 words each of which is paired with four pictures of objects: One semantically similar object (but visually dissimilar), one visually similar object (but semantically dissimilar), and two unrelated objects. Visual and semantic similarity ratings between corresponding items are provided for every picture for Dutch and for English. In addition, visual and linguistic parameters of each picture are reported. We thus present a stimulus set from which researchers can select, on the basis of various parameters, the items most optimal for their research question.     

Meaning above the head: combinatorial constraints on the visual vocabulary of comics

“Upfixes” are “visual morphemes” originating in comics where an element floats above a character’s head (ex. lightbulbs or gears). We posited that, similar to constructional lexical schemas in language, upfixes use an abstract schema stored in memory, which constrains upfixes to locations above the head and requires them to “agree” with their accompanying facial expressions. We asked participants to rate and interpret both conventional and unconventional upfixes that either matched or mismatched their facial expression (Experiment 1) and/or were placed either above or beside the head (Experiment 2). Interpretations and ratings of conventionality and face–upfix matching (Experiment 1) along with overall comprehensibility (Experiment 2) suggested that both constraints operated on upfix understanding. Because these constraints modulated both conventional and unconventional upfixes, these findings support that an abstract schema stored in long-term memory allows for generalisations beyond memorised individual items.     

Nuanced aesthetic emotions: emotion differentiation is related to knowledge of the arts and curiosity

The ability to distinguish between emotions is considered indicative of well-being, but does emotion differentiation (ED) in an aesthetic context also reflect deeper and more knowledgeable aesthetic experiences? Here we examine whether positive and negative ED in response to artistic stimuli reflects higher fluency in an aesthetic domain. Particularly, we test whether knowledge of the arts and curiosity are associated with more fine-grained positive and negative aesthetic experiences. A sample of 214 people rated their positive and negative feelings in response to various artworks including positive and negative themes. Positive ED was associated with the embracing sub-trait of curiosity that reflects engagement and enjoyment of novelty and complexity, but was unrelated to artistic knowledge and perceived comprehension. Negative ED was associated with higher curiosity and particularly more knowledge of the arts. This relationship was mediated by appraised comprehension suggesting that deeper engagement with art, by those with more art knowledge, is associated with more fine-grained emotional experiences. This finding extends ED beyond well-being research and suggests that more nuanced emotional experiences are more likely for those with expertise in the arts and motivation for exploration.     

情绪和时间辨别任务中视听整合与预先准备效应

本研究分别在时间和情绪认知维度上考察预先准备效应对情绪视听整合的影响。时间辨别任务(实验1)发现视觉引导显著慢于听觉引导,并且整合效应量为负值。情绪辨别任务(实验2)发现整合效应量为正值;在负性情绪整合中,听觉引导显著大于视觉引导;在正性情绪整合中,视觉引导显著大于听觉引导。研究表明,情绪视听整合基于情绪认知加工,而时间辨别会抑制整合;此外,跨通道预先准备效应和情绪预先准备效应都与引导通道有关。     

社会排斥对视觉工作记忆容量的影响

采用变化探测范式,考察社会排斥对非社会和社会性刺激视觉工作记忆容量的影响。发现社会排斥组的无意义图形视觉工作记忆容量显著小于社会接纳组,而对生物运动和面孔的记忆容量却显著大于社会接纳组。说明社会排斥对不同属性刺激的视觉工作记忆容量影响不同:社会排斥会损害与归属需要无关的非社会性刺激的记忆容量,而提高与归属需要有关的社会性刺激的记忆容量。

中国空间隐喻研究现状与发展趋势——基于CiteSpace的知识图谱分析

通过CiteSpace对空间隐喻研究文献进行可视化分析发现,中国对于空间隐喻的研究始于1999年,经历了起步探索期、爆发期,现进入平稳深化期; 学科分布以语言学为主,文学与心理学为辅; 多数研究者更倾向单次独立研究而缺少持续与合作研究,仅构成一个作者群,另外也有一些小合作团队,只局限于两人合作,合作力量较弱; 各机构之间合作缺乏; 研究热点集中于空间隐喻、隐喻、认知、意象图式、空间、映射汉语、隐喻拓展等,近年来转向了概念隐喻、道德、道德概念、垂直空间隐喻和具身认知,且具身认知持续至今; 空间隐喻研究主要围绕空间隐喻、认知语言学、意向图式、方位词、映射、隐喻、认知和具身认知这八个主题开展。由此可知,未来的研究中可扩展学科范围、加强各作者和各单位之间的合作、探索其他研究热点。     

Lexical orthographic knowledge acquisition in adults: The whole-word visual processing impact

IntroductionOne of the most persistent difficulties in French written language acquisition is lexical orthographic memorization. Both theoretical models and behavioral studies have suggested that simultaneous visual processing of all the letters of a word could be important for the acquisition of its orthographic form.Main goalTwo experiments are conducted to test this whole-word visual processing hypothesis.MethodThe paradigm used in both experiments is a self-teaching paradigm in which adult participants had to read orthographically complex bisyllabic pseudowords in isolation. In one reading condition, all the letters of the item are available at once, in the other the first and second syllables are seen successively. After reading, participants had to spell under dictation and to recognize the written items.ResultsGlobally, the results showed that participants better recall the orthographic form of a word after having read it in the whole-word reading condition. The result of the recognition task, in the second experiment, was in line with the result of the spelling under dictation task.ConclusionThese results, although they should be interpreted with caution, are in line with the whole-word visual processing hypothesis. Applied consequences for orthographic learning and teaching, as for remediation of specific orthographic disabilities, are discussed.
