A probed memory task was used to investigate children's short-term visual memory for an object's spatial location or colour. In Experiment 1, 5-yearolds recognised the location of one of three coloured shapes that had appeared in a random spatio-temporal order. Two aspects of the children's performance confirmed their reliance on visual memory. First, performance was impaired when the shapes were visually similar. Secondly, the serial position curve was characteristic of visual memory, with a final-item recency effect and no primacy effect. Experiment 2 assessed 5and 7-year-old children's memory for a shape's colour or its spatial location. Although there was developmental improvement in memory for spatial location, that was confined to pre-recency items, there was no effect of age with regard to the recall of colour. The results go against Hasher and Zacks' (1979) proposal that, in contrast to colour, spatial location would not show developmental improvement because it is remembered automatically. The concept of an object file, that was devised specifically to explain how different visual features of an object are represented (Kahneman & Treisman, 1984), is considered as a potential explanation of both the serial position curve and the distinctive behaviour of different visual features. It is suggested that although 5-year-olds are as adept as 7-year-olds at creating and immediately accessing an object file, they are less able to access information about the visual features of objects whose files are no longer current.
Students with Special Educational Needs and Disabilities encounter complex and circuitous transitions from post‐primary settings to Higher Education. In Ireland, inequitable access to Individual Education Plans, and a lack of policy infrastructure to provide formal transition planning, means that these journeys are varied and uncertain. This study presents findings from surveys completed by parents supporting students with disabilities in their final 3 years of mainstream secondary school (n = 69), and in‐depth interviews with a self‐selected subset of parents (n = 8). Results point to: (i) disparate levels and quality of support and guidance, (ii) fissures in communication channels between parents and schools, (iii) insufficient awareness and understanding of the interplay between disability and successful post‐school outcomes, and (iv) high levels of stress, anxiety and frustration experienced by students, parents and carers.
Pathological demand avoidance (PDA) is contended to be a distinct presentation within autism characterised by extreme levels of anxiety in response to the demands of everyday life, manifested in excessive levels of demand avoidance. This results in complex interactions with service providers in education and health settings, impacting on outcomes for individuals and their families. This national study sought to gather the viewpoints of individuals who experience PDA, families, and practitioners, with the intention of determining levels of knowledge, recognition and understanding of PDA; exploring current pathways to assessment and diagnosis; capturing experiences of access to education and healthcare services; identifying effective intervention and support strategies; and illuminating education and health outcomes for individuals and families. This mixedmethod study collates survey responses from N = 264 parents, N = 9 life partners, N = 6 individuals experiencing PDA and N = 54 practitioners, and in-depth individual and focus group interviews from these cohorts. Findings suggest that a flexible, informed and individualised approach to assessment and service provision for individuals presenting with a PDA profile is essential. Practitioners universally referred to the necessity for a streamlined, integrated and multi-disciplinary approach. The reported disconnect between education and health systems indicates a need for access to services on an equitable basis.
Many theories of semantic representation propose that simulations of sensorimotor experience contribute to language processing. This can be seen in the body-object interaction effect (BOI; how easily the human body can interact with a word’s referent). Words with high BOI ratings (e.g., ball) are processed more quickly than words with low BOI ratings (e.g., cloud) in various language tasks. This effect can be modulated by task demands. Previous research established that when asked to decide if a word is an object (entity condition), a BOI effect is observed, but when asked to decide if a word is an action (action condition), there is no BOI effect. It is unclear whether the null behavioral effect in the action condition reflects top-down modulation of task-relevant sensorimotor information or the absence of bottom-up activation of sensorimotor simulations. We investigated this question using EEG. In Experiment 1 we replicated the previous behavioral findings. In Experiment 2, 50 participants were assigned to either the entity or action conditions and responded to the same word stimuli. In both conditions we observed differences in ERP components related to the BOI effect. In the entity condition the P2 mean amplitude was significantly more positive for high compared to low BOI words. In the action condition the N400 peak latency was significantly later for high compared to low BOI words. Our findings suggest that BOI information is generated bottom-up regardless of task demands and modulated by top-down processes that recruit sensorimotor information relevant to the task decision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
