Greater eyes-focused eye movement pattern during face recognition is associated with better performance in adults but not in children. We test the hypothesis that higher eye movement consistency across trials, instead of a greater eyes-focused pattern, predicts better performance in children since it reflects capacity in developing visual…

We assessed the association between dynamic changes in pupil response in the context of visual perception and quantitative measures of the autism phenotype in healthy adults. Using Navon stimuli in a task-switching paradigm, participants were instructed to identify global or local information based on a cue. Multiple pupil response trajectories…

Although statistical learning (SL) has been studied extensively in developmental dyslexia (DD), less attention has been paid to other fundamental challenges in language acquisition, such as cross-situational word learning. Such investigation is important for determining whether and how SL processes are affected in DD at the word level. In this…

When too much visual stimuli is present, the phenomenon of clutter is known to degrade an individual's perception across a variety of domains, ranging from completing search tasks incorrectly, to decreasing reading speed when letters are too close together. However, research is lacking as to whether the negative effects of clutter impact learning…

This study explored performance on expressive and receptive graphic symbol tasks and spoken comprehension by individuals who use augmentative and alternative communication (AAC) as well as the relationship of performance with participants' skills and characteristics. Participants were 19 children and youth (aged 5- to 18-years-old) who used aided…

By approximately 6 years of age, children can use time-based visual selection to ignore stationary stimuli, already in the visual field and prioritize the selection of newly arriving stimuli. This ability can be studied using preview search, a version of the visual search paradigm with an added temporal component, in which one set of distractors…

It has been suggested that attenuated adaptation to visual stimuli in autism is the result of atypical perceptual priors (e.g., Pellicano and Burr in "Trends Cogn Sci" 16(10):504-510, 2012. doi:10.1016/j.tics.2012.08.009). This study investigated adaptation to color in autistic adults, measuring both strength of afterimage and the…

To facilitate multisensory processing, the brain binds multisensory information when presented within a certain maximum time lag (temporal binding window). In addition, and in audiovisual perception specifically, the brain adapts rapidly to asynchronies within a single trial and shifts the point of subjective simultaneity. Both processes, temporal…

Visuospatial processing speed underlies several cognitive functions critical for successful completion of everyday tasks, including driving and walking. While it is widely accepted that visuospatial processing speed peaks in early adulthood, performance across the lifespan remains incompletely characterized. Additionally, there remains a lack of…

Are oral sentences accompanied by pictures easier to understand than written sentences accompanied by the same pictures? This question--intensely discussed for more than two decades in educational, psychological, and psycholinguistic research in terms of "modality effect in multimedia learning," "split-attention effect," or…

Selective attention is fundamental for learning across many situations, yet it exhibits protracted development, with young children often failing to filter out distractors. In this research, we examine links between selective attention and working memory (WM) capacity across development. One possibility is that WM is resource-limited, with…

This research examined how 5-, 8-, and 11-month-olds with female primary caregivers mentally represented faces using a familiarization procedure similar to real-world experience in which infants have greater exposure to female faces aged 21-39 years than other face types. We predicted infants would form weighted representations of faces (i.e.,…

Categories are fundamental to everyday life and the ability to learn new categories is relevant across the lifespan. Categories are ubiquitous across modalities, supporting complex processes such as object recognition and speech perception. Prior work has proposed that different categories may engage learning systems with unique developmental…

Purpose: We review and interpret our recent series of studies investigating motor-to-auditory influences during speech movement planning in fluent speakers and speakers who stutter. In those studies, we recorded auditory evoked potentials in response to probe tones presented immediately prior to speaking or at the equivalent time in no-speaking…

Social abilities relate to performance on visual-spatial perspective-taking (VSPT) tasks for hearing nonsigners but may relate differently to VSPT abilities for deaf signers because of their distinct linguistic and social experiences. This research investigated whether deaf adults approach VSPT tasks nonsocially (as previously suggested for deaf…
