People with autism perceive drastic illusory changes for repeated verbal stimuli

Do Fish Perceive Illusory Motion?

Motion illusion refers to a perception of motion that is absent or different in the physical stimulus. These illusions are a powerful non-invasive tool for understanding the neurobiology of vision because they tell us, indirectly, how we process motion. There is general agreement in ascribing motion illusion to higher-level processing in the visual cortex, but debate remains about the exact rol...

Can adolescents with autism perceive emotional prosody?

Past findings on the perception of emotional prosody by individuals with Autism Spectrum Disorder (ASD) have been incongruent, and a main reason is the lack of clarity about the contributions of specific acoustic features to emotion perception. In this study we test the perception of emotional prosody by adolescents with ASD using a recently developed prosody control method based on a bio-infor...

Differential processing of immediately repeated verbal and non-verbal stimuli: an evoked-potential study.

Stimuli are better retained in memory if they are repeated after a delay than if they are immediately repeated. This effect is called the spacing effect (SE). Recent electroencephalographic (EEG) studies showed that delayed repetition of meaningful designs in a continuous recognition task induces an evoked response very similar to new presentations. In contrast, immediately repeated designs ind...

Tidy or Tangled: How People Perceive Landscapes

Conducting research with minimally verbal participants with autism spectrum disorder.

A growing number of research groups are now including older minimally verbal individuals with autism spectrum disorder in their studies to encompass the full range of heterogeneity in the population. There are numerous barriers that prevent researchers from collecting high-quality data from these individuals, in part because of the challenging behaviors with which they present alongside their v...
