Reduced social attention is characteristic of Autism Spectrum Disorder (ASD). It has been suggested to result from an early onset and excessive influence of circumscribed interests (CIs) on gaze behaviour, compared to typically developing (TYP) individuals. To date, these findings have been mixed. The current eye-tracking study utilised a visual…

The development of the ability to anticipate--as manifested by preparatory actions and neural activation related to the expectation of an upcoming stimulus--may play a key role in the ontogeny of cognitive skills more broadly. This preregistered study examined anticipatory brain potentials and behavioral responses (reaction time; RT) to…

The social communicative deficits and repetitive behaviours seen in Autism Spectrum Disorder (ASD) may be affected by altered stimulus salience and reward attribution. The present study used eye tracking and a behavioural measure to index effort expenditure, arousal, and attention, during viewing of images depicting social scenes and…

Nonverbal and other visual cues are well established as a critical component of human communication. Under most circumstances, visual information is available to aid in the comprehension and interpretation of spoken language. Citing these facts, many L2 assessment researchers have studied video-mediated listening tests through score comparisons…

The study of visual attention in infants has used presentation of single simple stimuli, multi-dimensional stimuli, and complex dynamic video presentations. There are both continuities and discontinuities in the findings on attention and attentiveness to stimulus complexity. A continuity is a pattern of looking that is found in the early part of…

This study is the third of three investigating attentional preference in infants. In the second study (PS 003 071), infants gave initial attentional preference to familiar patterns of visual stimuli, and later switched their preference to the unfamiliar, novel stimuli. The purpose of the present study was to duplicate these results with improved…

The human infant is now considered capable of active informational interaction with the environment. This study tested certain hypotheses concerning the nature of that interaction. These hypotheses, developed partly from Piaget's work, are (1) that repeated visual encounters with a stimulus pattern leads first to attentional preference for that…

A total of 48 8- to 14-week-old infants were presented with a non-contingently moving visual stimulus and the infants' visual attention was measured. Infants who exhibited decrements in attention to the non-contingent stimulus showed recovery in attention when the same stimulus was made to move contingent upon a motor response. Moreover, wisual…

Two studies investigated whether 10- to 11-month-olds possess skills for parsing ongoing behavior along boundaries correlated with initiation and completion of intentions. Found that infants showed renewed interest in test videos in which motion paused in the midst of an actor's pursuit of intentions; suspended motion at intentional boundary…
