Tell me where it is: Selective difficulties in spatial language on the autism spectrum

Proficient use of spatial terms such as under, to the left of or in front of is a central component of daily communication and is important in the development of language and spatial cognition. Here we examine spatial language abilities in intellectually high-functioning individuals with autism spectrum disorder, an area previously overlooked in autism research. Twenty-five high-functioning individuals with ASD and 25 typically developing controls, matched for chronological age and cognitive abilities, completed a novel battery tapping a broad range of spatial language abilities. We report selective difficulties in the production of spatial terms and spatial description recall in high-functioning ASD. Overall verbal abilities did not account for the observed group differences. Crucially, however, the intensity of autism spectrum traits predicted individual performance in both spatial language production and spatial description recall. We discuss the theoretical implications of these findings and explore their significance for both clinical practice and intervention. Lay abstract: How we think and talk about space is an essential ability, necessary for understanding the world around us. We recruit spatial thinking every day when finding our way or using tools but also in more advanced tasks, such as reading complex graphs or maps. We do so also in daily communication when we use spatial language, terms such as under, over, to the left of or in front of, and when we give instructions. Spatial terms appear in children’s early vocabularies and continue to develop until late childhood or even early adolescence. Because spatial language develops over many years, some spatial terms are mastered very early, whereas others take longer to acquire. In the current set of studies, we tested how intellectually high-functioning children and adults on the autism spectrum use and understand these early- and late-acquired spatial terms in comparison to typically developing age-matched individuals. We found that children and adults on the autism spectrum experience difficulties with the use of some spatial terms (e.g. near and far or out of and down off) but not with others, which are acquired early (e.g. in and on or over and under). We also found that remembering spatial terms from short stories was more difficult for the individuals on the autism spectrum compared with typically developing individuals. These results reveal difficulties that can profoundly affect everyday communication of children and adults on the autism spectrum but also open new directions of research on language development in autism spectrum disorders

Teaching open and reproducible scholarship: a critical review of the evidence base for current pedagogical methods and their outcomes

In recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergraduate and postgraduate research training. Specifically, a critical overview of the literature which investigates how integrating open and reproducible science may influence student outcomes is needed. In this paper, we provide the first critical review of literature surrounding the integration of open and reproducible scholarship into teaching and learning and its associated outcomes in students. Our review highlighted how embedding open and reproducible scholarship appears to be associated with (i) students' scientific literacies (i.e. students’ understanding of open research, consumption of science and the development of transferable skills); (ii) student engagement (i.e. motivation and engagement with learning, collaboration and engagement in open research) and (iii) students' attitudes towards science (i.e. trust in science and confidence in research findings). However, our review also identified a need for more robust and rigorous methods within pedagogical research, including more interventional and experimental evaluations of teaching practice. We discuss implications for teaching and learning scholarship

The functional role of gaze scanpaths in long-term visual memory

Eye movements occur spontaneously during recall from the visual memory despite neither the object nor context remembered may be visible at the time of recall. Recent research provides support for the hypothesis that these eye movements could play a functional role in the retrieval of stored information by matching the original eye fixations from the time of encoding. However, studies have provided conflicting results in this field. To investigate this, we designed a novel experimental procedure where the eye scanpaths from encoding were forced to be either enacted or not during recognition of the image. Simple geometrical patterns resembling checkerboards were used as stimuli in the current experiment. We hypothesized that enactment of the original scanpath would facilitate memory retrieval. Observed results supported the predictions, which is in accordance with theories pointing to a functional role of eye movements in long-term memory

Young children’s drawings and descriptions of layouts and objects

Young children tend to prioritize objects over layouts in their drawings, often juxtaposing “floating” objects in the picture plane instead of grounding those objects in drawn representations of the extended layout. In the present study, we explore whether implicitly directing children’s attention to elements of the extended layout through a drawing’s communicative goal—to indicate the location of a hidden target to someone else—might lead children to draw more layout information. By comparing children’s drawings to a different group of children’s verbal descriptions, moreover, we explore how communicative medium affects children’s inclusion of layout and object information. If attention modulates children’s symbolic communication about layouts and objects, then children should both draw and talk about layouts and objects when they are relevant to the communicative task. If there are challenges or advantages specific to either medium, then children might treat layouts and objects differently when drawing versus describing them. We find evidence for both of these possibilities: Attention affects what children include in symbolic communication, like drawings and language, but children are more concise in their inclusion of relevant layout or object information in language versus drawings

Classifiers in non-European languages and semantic impairments in western neurological patients have a common cognitive structure

We compared two non-overlapping data sets: (a) the semantic categories in representative samples of nominal classification languages (N = 334); and in a non-overlapping population (b) semantic category-specific impairments of European neurological patients (N = 121). Each of these appears to organize world objects in natural kinds (e.g., animal, body part, plant, fruit and vegetable, liquid) or manmade kinds (e.g., food, clothing, tool, vehicle, furniture). We show that whenever a specific semantic category is found as a cognitive impairment, this category also exists in some language as a semantic classifier. Since all of the existing semantic impairments reports are with speakers whose languages lack semantic nominal classification systems, the present regularities between grammar and cognitive deficit suggests the idea that cognitive universals may constrain how the neural substrate of knowledge is organized and can break apart but also how they can become expressed in different grammars

More mental rotation time does not imply more mental effort: Pupillary diameters do not change with angular distance

The ability to mentally rotate objects in space is a fundamental cognitive capacity. Previous studies showed that the time to rotate the image of a figure to match another increases progressively with angular disparity. It remains unclear whether this increase in response time with angular disparity could reflect increased processing operations or more cognitive effort instead of a sustained use of a ‘rotate’ mechanism without a change in workload. We collected response times as well as pupillary responses that index cognitive workload and activity in the brainstem's locus coeruleus, from a sample of 38 young adults performing a chronometric mental rotations task. The results showed the expected increase in response times but no increase in pupil diameters between 60, 120, and 180 degrees of rotation, suggesting no significant changes in arousal levels when rotating figures near and far. This indicates that during mental rotation the load on cognitive resources remains constant irrespective of angular distance
