阅读理解困难儿童的认知加工

阅读理解困难是阅读障碍的一个主要类型,近年来受到西方研究者的重视。阅读理解认知加工,核心是有层次的语义加工,理解困难儿童在词汇语义加工和篇章推理和整合上都存在落后。理解困难儿童的信息推理水平落后,可能原因来自两个方面：一方面是语音工作记忆缺陷导致推理加工能力缺陷,另一方面是阅读元认知缺陷导致阅读目的和理解监控发展不正常。这些缺陷之间复杂的关系,还需要进一步研究     

Transnational families,remittances, cieng and obligation for Dinka women in Australia

This paper explores the narratives of a group of Dinka women living in Australia with a focus on the emotional underpinnings of remittance sending to family in Africa. The sending of remittances is shaped by the Dinka relational ontology of cieng which obliges those who have migrated to Australia to financially support relatives left behind in Africa. Through exploring the ‘emotional content of obligation’ (Clark, 1990) this paper considers how cieng and remittance sending can result in feelings including shame and helplessness but also in reinforcing a sense belonging. In addition, this paper argues that while there is continuity in cieng despite the global dispersal of Dinka people, there has been a change in the degree and type of obligation placed on people through cieng.     

At the Nexus of cinema,city and memory: Resisting the demolition of Istanbul's historical Emek movie theatre

Emek was the oldest surviving movie theatre in Istanbul when it was demolished in 2013 so that a shopping mall could be built in its place, spawning a persistent civic resistance. Sitting at the juxtaposition of the vibrant literatures on urban studies, film studies, and memory studies, the article demonstrates that emotions, evoked by memories, have a part in triggering urban resistance, adding to the flourishing literature on how emotions inspire and sustain activism. Specifically, it provides ethnographic evidence for the presence of a positive link between place attachment and willingness to engage in place-protective behaviour, stressing the role played by memories in this regard. Focusing on a historical movie theatre, on the other hand, also reveals the complex spatiality of cinematic experience, stressing the importance of social relations and vicinity of the theatre (the street in particular) in this specific context. A final set of contributions derived from the case of Emek relates to the notions of “failure” and “sustainability of activism” given that the resistance to Emek's demolition is characterised by its resilience and persistence as well as a determination to “resist to forget”, despite the failure, practices of emotional reflexivity playing a key role in this respect.     

The mood-enhancement function of autobiographical memories: Comparisons with other functions in terms of emotional valence

In two studies, we examined the emotional valence of memories used for mood-enhancement in relation to memories serving self, social and directive functions. Our sample included a total of 263 participants aged between 45 and 82 years. In Study 1, participants recalled memories in response to 51 cue words. In Study 2, participants recalled 32 memories that served the four functions (eight memories per function). We used multilevel modeling to take into consideration the hierarchical nature of our datasets (memories nested within individuals). Study 1 showed that emotional valence was positively associated with mood-enhancement and social functions, whereas negatively related to self and directive functions. This relation was strongest for the mood-enhancement function. In Study 2, mood-enhancing memories were rated as more positive than self, social and directive memories. We discussed results in terms of the tripartite model of memory functions and proposed that mood-enhancement should represent a distinct function.     

Adaptive processing of fractions — Evidence from eye-tracking

Recent evidence indicated that fraction pair type determined whether a particular fraction is processed holistically, componentially or in a hybrid manner. Going beyond previous studies, we investigated how participants adapt their processing of fractions not only to fraction type, but also to experimental context. To examine adaptation in fraction processing, we recorded participants' eye-fixation behaviour in a fraction magnitude comparison task.     

Emotional modulation of attention affects time perception: Evidence from event-related potentials

Emotional effects on human time perception are generally attributed to arousal speeding up or slowing down the internal clock. The aim of the present study is to investigate the less frequently considered role of attention as an alternative mediator of these effects with the help of event-related potentials (ERPs). Participants produced short intervals (0.9, 1.5, 2.7, and 3.3 s) while viewing high arousal images with pleasant and unpleasant contents in comparison to neutral images. Behavioral results revealed that durations were overproduced for the 0.9 s interval whereas, for 2.7 and 3.3 s intervals, underproduction was observed. The effect of affective valence was present for the shorter durations and decreased as the target intervals became longer. More specifically, the durations for unpleasant images were less overproduced in the 0.9 s intervals, and for the 1.5 s trials, durations for unpleasant images were slightly underproduced, compared to pleasant images, which were overproduced. The analysis of different ERP components suggests possible attention processes related to the timing of affective images in addition to changes in pacemaker speed. Early Posterior Negativity (EPN) was larger for positive than for negative images, indicating valence-specific differences in activation of early attention mechanisms. Within the early P1 and the Late Positive Potential (LPP) components, both pleasant and unpleasant stimuli exhibited equal affective modulation. Contingent Negative Variation (CNV) remained independent of both timing performance and affective modulation. This pattern suggests that both pleasant and unpleasant stimuli enhanced arousal and captured attention, but the latter effect was more pronounced for pleasant stimuli. The valence-specificity of affective attention revealed by ERPs combined with behavioral timing results suggests that attention processes indeed contribute to emotion-induced temporal distortions, especially for longer target intervals.     

The association between children's numerical magnitude processing and mental multi-digit subtraction

Children apply various strategies to mentally solve multi-digit subtraction problems and the efficient use of some of them may depend more or less on numerical magnitude processing. For example, the indirect addition strategy (solving 72–67 as “how much do I have to add up to 67 to get 72?”), which is particularly efficient when the two given numbers are close to each other, requires to determine the proximity of these two numbers, a process that may depend on numerical magnitude processing. In the present study, children completed a numerical magnitude comparison task and a number line estimation task, both in a symbolic and nonsymbolic format, to measure their numerical magnitude processing. We administered a multi-digit subtraction task, in which half of the items were specifically designed to elicit indirect addition. Partial correlational analyses, controlling for intellectual ability and motor speed, revealed significant associations between numerical magnitude processing and mental multi-digit subtraction. Additional analyses indicated that numerical magnitude processing was particularly important for those items for which the use of indirect addition is expected to be most efficient. Although this association was observed for both symbolic and nonsymbolic tasks, the strongest associations were found for the symbolic format, and they seemed to be more prominent on numerical magnitude comparison than on number line estimation.     

Aging and individual differences in binding during sentence understanding: Evidence from temporary and global syntactic attachment ambiguities

We report an investigation of aging and individual differences in binding information during sentence understanding. An age-continuous sample of adults (N = 91), ranging from 18 to 81 years of age, read sentences in which a relative clause could be attached high to a head noun NP1, attached low to its modifying prepositional phrase NP2 (e.g., The son of the princess who scratched himself/herself in public was humiliated), or in which the attachment site of the relative clause was ultimately indeterminate (e.g., The maid of the princess who scratched herself in public was humiliated). Word-by-word reading times and comprehension (e.g., who scratched?) were measured. A series of mixed-effects models were fit to the data, revealing: (1) that, on average, NP1-attached sentences were harder to process and comprehend than NP2-attached sentences; (2) that these average effects were independently moderated by verbal working memory capacity and reading experience, with effects that were most pronounced in the oldest participants and; (3) that readers on average did not allocate extra time to resolve global ambiguities, though older adults with higher working memory span did. Findings are discussed in relation to current models of lifespan cognitive development, working memory, language experience, and the role of prosodic segmentation strategies in reading. Collectively, these data suggest that aging brings differences in sentence understanding, and these differences may depend on independent influences of verbal working memory capacity and reading experience.     

Auditory local bias and reduced global interference in autism

Processing local elements of hierarchical patterns at a superior level and independently from an intact global influence is a well-established characteristic of autistic visual perception. However, whether this confirmed finding has an equivalent in the auditory modality is still unknown. To fill this gap, 18 autistics and 18 typical participants completed a melodic decision task where global and local level information can be congruent or incongruent. While focusing either on the global (melody) or local level (group of notes) of hierarchical auditory stimuli, participants have to decide whether the focused level is rising or falling. Autistics showed intact global processing, a superior performance when processing local elements and a reduced global-to-local interference compared to typical participants. These results are the first to demonstrate that autistic processing of auditory hierarchical stimuli closely parallels processing of visual hierarchical stimuli. When analyzing complex auditory information, autistic participants present a local bias and a more autonomous local processing, but not to the detriment of global processing.     

Number processing of Arabic and Hebrew bilinguals: Evidence supporting the distance effect

In the current study, a direct assessment of the effect of language lexical‐syntactic structure and magnitude semantic access on numerical processing was made by contrasting the performance of Arabic/Hebrew bilinguals in a digital (Hindi‐digits/Arabic‐digits) and verbal numerical comparison task (Arabic, an inverted language: Units‐Decades, Hebrew, a non‐inverted language: Decades‐Units). Our data revealed in the digital presentation format (Experiment 1) a regular distance effect in Arabic language‐Hindi digits and Hebrew language‐Arabic digits, characterized by an inverse relation between reaction times and numerical distance with no difference in the mean reaction times of participants in Arabic‐L1 and Hebrew‐L2. This indicates that both lexical digits of two‐digit numbers in L1 and L2 are similarly processed and semantically accessed. However in the verbal presentation format (Experiment 2) a similar pattern of distance effect was found, but the mean reaction times in Arabic were lower than in Hebrew in each numerical distance. This indicates that the processing of two‐digit number words in L1 and L2 is semantically accessed and determined by the syntactic structure of each language.
