An attempt to simulate letter-by-letter dyslexia in normal readers

We attempted to simulate the main features of letter-by-letter (LBL) dyslexia in normal readers through stimulus degradation (i.e. contrast reduction and removal of high spatial frequencies). The results showed the word length and the letter confusability effects characteristic of LBL dyslexia. However, the interaction of letter confusability and N size (i.e. a facilitatory effect only for low confusability targets) previously observed in LBL dyslexics [Arguin, M., Fiset, S., & Bub, D. (2002). Sequential and parallel letter processing in letter-by-letter reading. Cognitive Neuropsychology, 19, 535-555; Arguin, M., & Bub, D. (2006). Parallel processing blocked by letter similarity in letter dyslexia: a replication. Cognitive Neuropsychology, 22, 589-602; Fiset, D., Arguin, M. & McCabe, E. (2005a). The breakdown of parallel letter processing in letter-by-letter dyslexia. Cognitive Neuropsychology, 22, 1-22] was not found. Our results suggest that the type of visual degradation employed here may only partially correspond to the visual deficit present in LBL dyslexia and that this degradation may have prevented the normal readers from accessing visual information available to LBL dyslexics when they use the compensatory strategy of serial letter processing.     

Not all skilled readers have cracked the code: individual differences in masked form priming

This experiment investigated whether individual differences in written language proficiency among university students predict the early stages of lexical retrieval tapped by the masked form priming lexical decision task. To separate the contributions of sublexical facilitation and lexical competition to masked form priming, the effects of prime lexicality were directly compared for both transposed-letter (TL) primes (e.g., sung SNUG; salb SLAB) and neighbor primes (e.g., snag SNUG; sleb SLAB) in a sample of 100 university students assessed on measures of reading, spelling and vocabulary. The data for the whole sample showed facilitation from nonword primes, but inhibition from word primes. Linear mixed models including the individual difference measures showed that higher scores on a principal component that captured the shared variance among reading, spelling, and vocabulary were associated with both stronger inhibition from TL word primes and stronger facilitation from neighbor nonword primes. These findings are consistent with the lexical quality hypothesis of reading that predicts that skilled readers vary in the extent to which they have developed precisely specified orthographic representations.     

Self-care for academics: a poetic invitation to reflect and resist

In newspapers and blogs, on Twitter, and in academic papers, stories of struggling academics abound. Substance abuse, depression, failed relationships, and chronic illness are the casualties of a neoliberal university sector that values quantity over quality and demands ever more for ever less. Within the academic literature a growing counter-movement has called for resistance, collective action, and slow scholarship. Much of this work, however, has focused on strategies that can be applied within academia. Little has been written about the activities that academics do outside the university; activities that have no purpose other than enjoyment, rest, and renewal; activities that represent the valuing of the self as a human being, rather than a means of production; activities that could best be defined as self-care. Using reflective practice to construct a poem comprising three voices, this paper explores those activities. This poetic representation is an effort to create time and space for the authors, and a manifesto to encourage other academics to demand and protect the time, space, and reflective practice that are essential to both personal wellbeing and quality research and education.     

What readers bring to the processing of fictional texts

Research on text processing has generally focused on the types of inferences that all readers draw in common. Our research examines aspects of processing that depend on the particular relation of the reader to the text. Students read fictional stories that contained weak and unsupported assertions and that were set either at their own school or at another school. We expected that they would be prompted to process the story information thoroughly enough to reject the assertions only if they were familiar with the story setting. Consistent with this expectation, the results showed that the away-school story, but not the home-school story, had a significant impact on students’ beliefs. These results support the view that readers must actively construct disbelief when processing fictional information.     

Children prefer to learn from mind‐readers

Kim and Harris ( 2014 , J. Cogn. Dev.) showed that children selectively learned from an informant who produced apparently magical outcomes as compared to another informant who produced only ordinary outcomes in the domain of everyday physics. In the present study, we tested children's ability to differentiate between and selectively learn from informants who displayed either an extraordinary or an ordinary ability in the domain of everyday psychology. Prior studies have shown that children come to appreciate what is ordinarily involved in knowing the private mental states of other people. Drawing on this research, we asked whether 3‐ to 4‐ and 5‐ to 6‐year‐old children preferentially learned from an informant who knew another person's mind via either an ordinary or an extraordinary form of communication. As compared to younger children, older children were more likely to learn from the extraordinary informant. Moreover, children's ability to differentiate between the two informants was a better predictor of their learning from the extraordinary informant than age. We discuss the findings in the light of prior work on selective learning, children's ideas about prayer and their understanding of impossibility.     

Not all phonological awareness deficits are created equal: evidence from a comparison between children with Otitis Media and poor readers

Children with reading difficulties and children with a history of repeated ear infections (Otitis Media, OM) are both thought to have phonological impairments, but for quite different reasons. This paper examines the profile of phonological and morphological awareness in poor readers and children with OM. Thirty‐three poor readers were compared to individually matched chronological age and reading age controls. Their phonological awareness and morphological awareness skills were consistently at the level of reading age matched controls. Unexpectedly, a significant minority (25%) of the poor readers had some degree of undiagnosed mild or very mild hearing loss. Twenty‐nine children with a history of OM and their matched controls completed the same battery of tasks. They showed relatively small delays in their literacy and showed no impairment in morphological awareness but had phonological awareness scores below the level of reading age matched controls. Further analysis suggested that this weakness in phonological awareness was carried by a specific weakness in segmenting and blending phonemes, with relatively good performance on phoneme manipulation tasks. Results suggest that children with OM show a circumscribed deficit in phoneme segmentation and blending, while poor readers show a broader metalinguistic impairment which is more closely associated with reading difficulties.     

小学五年级语文学优生与学困生阅读知觉广度的眼动研究

本研究以眼动仪为工具,采用移动窗口范式来考察小学五年级语文学优生和学困生的阅读知觉广度。实验结果发现,小学五年级语文学优生的阅读知觉广度范围为注视字左侧一个汉字到注视字右侧三个汉字,小学五年级语文学困生的阅读知觉广度范围为注视字左侧一个汉字到注视字右侧两个汉字。小学五年级语文学优生的阅读知觉广度比学困生更大。
