Contributions of linguistic,quantitative, and spatial attention skills to young children's math versus reading: Same,different, or both?

The study used Bayesian and Frequentist methods to investigate whether the roles of linguistic, quantitative, and spatial attention skills are distinct in children's acquisition of reading and math. A sample of 175 Chinese kindergarteners was tested with measures of linguistic skills (phonological awareness and phonological memory), quantitative knowledge (number line task, symbolic digit comparison, and non-symbolic number estimation), spatial attention skills (visual span, mental rotation, and visual search), word reading, and calculation. After statistically controlling for age and nonverbal intelligence, phonological awareness and digit comparison performance explained unique variance in both math and reading. Moreover, number line estimation was specifically important for math, while phonological memory was specifically essential for reading. These findings highlight the possibility of developing early screening tools with different cognitive measures for children at risk of learning disabilities in reading and/or math.     

Syntactic prediction during self-paced reading is age invariant

Controversy exists as to whether, compared to young adults, older adults are more, equally or less likely to make linguistic predictions while reading. While previous studies have examined age effects on the prediction of upcoming words, the prediction of upcoming syntactic structures has been largely unexplored. We compared the benefit that young and older readers gain when the syntactic structure is made predictable, as well as potential age differences in the costs involved in making predictions. In a self-paced reading study, 60 young and 60 older adults read sentences in which noun-phrase coordination (e.g. large pizza or tasty calzone) is made predictable through the inclusion of the word either earlier in the sentence. Results showed a benefit of the presence of either in the second half of the coordination phrase, and a cost of the presence of either in the first half. We observed no age differences in the benefit or costs of making these predictions; Bayes factor analyses offered strong evidence that these effects are age invariant. Together, these findings suggest that both older and younger adults make similar strength syntactic predictions with a similar level of difficulty. We relate this age invariance in syntactic prediction to specific aspects of the ageing process.     

Socio-cognitive,expertise-based and appearance-based accounts of the other-‘race’ effect in face perception: A label-based systematic review of neuroimaging results

Two competing theories explain the other-‘race’ effect (ORE) either by greater perceptual expertise to same-‘race’ (SR) faces or by social categorization of other-‘race’ (OR) faces at the expense of individuation. To assess expertise and categorization contributions to the ORE, a promising—yet overlooked—approach is comparing activations for different other-‘races’. We present a label-based systematic review of neuroimaging studies reporting increased activity in response to OR faces (African, Caucasian, or Asian) when compared with the SR of participants. Hypothetically, while common activations would reflect general aspects of OR perception, ‘race’-preferential ones would represent effects of ‘race’-specific visual appearance. We find that several studies report activation of occipito-temporal and midcingulate areas in response to faces across different other-‘races’, presumably due to high demand on the visual system and category processing. Another area reported in response to all OR faces, the caudate nucleus, suggests the involvement of socio-affective processes and behavioural regulation. Overall, our results support hybrid models—both expertise and social categorization contribute to the ORE, but they provide little evidence for reduced motivation to process OR faces. Additionally, we identify areas preferentially responding to specific OR faces, reflecting effects of visual appearance.     

Spatial attention based on 2D location and relative depth order modulates visual working memory in a 3D environment

The attentional effect on visual working memory (VWM) has been a heated research topic in the past two decades. Studies show that VWM performance for an attended memory item can be improved by cueing its two-dimensional (2D) spatial location during retention. However, few studies have investigated the effect of attentional selection on VWM in a three-dimensional setting, and it remains unknown whether depth information can produce beneficial attentional effects on 2D visual representations similar to 2D spatial information. Here we conducted four experiments, displaying memory items at various stereoscopic depth planes, and examined the retro-cue effects of four types of cues – a cue would either indicate the 2D or depth location of a memory item, and either in the form of physical (directly pointing to a location) or symbolic (numerically mapping onto a location) cues. We found that retro-cue benefits were only observed for cues directly pointing to a 2D location, whereas a null effect was observed for cues directly pointing to a depth location. However, there was a retro-cue effect when cueing the relative depth order, though the effect was weaker than that for cueing the 2D location. The selective effect on VWM based on 2D spatial attention is different from depth-based attention, and the divergence suggests that an object representation is primarily bound with its 2D spatial location, weakly bound with its depth order but not with its metric depth location. This indicates that attentional selection based on memory for depth, particularly metric depth, is ineffective.     

Effects of phonological awareness and morphological awareness on blind students' reading comprehension

The exploration of blind students' reading skills is needed not only for further understanding their reading development but also for providing targeted suggestions for practical education. This study aims to examine the relations among phonological awareness (PA), homograph awareness (HA), compounding awareness (CA) and reading comprehension (RC), and explore the mediating effect of listening comprehension (LC) in Chinese blind students from elementary school. A total of 148 blind and 302 sighted elementary school students completed assessments of PA, HA, CA, LC and RC. The results found that PA, HA and CA were important variables that predicted Chinese blind and sighted students' RC not only directly but also indirectly through LC, which varied across different grades. The findings suggest that there were many similarities that exist in the influencing mechanism of RC between Chinese blind and sighted students.     

Argumentation, the Visual, and the Possibility of Refutation: An Exploration

Taking the possibility of visual argumentation seriously, this essay explores how refutation might proceed. We posit three ways in which images can refute and be refuted in a mixed-media environment: (1) dissection, in which an image is broken down discursively; (2) substitution, in which one image is replaced within a larger visual frame by a different image; and (3) transformation, in which an image is recontextualized in a new visual frame. These strategies are illustrated in an analysis of three American documentary films on abortion.     

The Case for Early Intervention in Diagnosing Specific Reading Disability

In the present article, we argue against the use of psychometric assessment as the primary or sole vehicle for diagnosing specific reading disability. We suggest instead that the diagnostic enterprise should be initiated with early and labor intensive remedial intervention, and that the child’s ability to profit from such intervention should be the most important piece of information in making the diagnosis, notwithstanding the confirmatory value of psychometric assessment in given cases. We support our arguments with selected findings from an intervention study we have recently completed demonstrating that most children who perform poorly in reading can be readily brought to at least an average level of performance if their reading difficulties are addressed at the beginning stage of reading development.     

Using Brief Functional Analysis to Select Interventions for Oral Reading

Reading interventions were applied in a brief multielement format to examine their effectiveness at improving the oral reading fluency of three students referred for reading problems. Although each student had different profiles across experimental analyses, effective interventions were identified and a mini-replication confirmed the pattern of results in each case.
