Shuwairi, Sarah M.; Johnson, Scott P. – Infancy, 2013
Previous studies have revealed that young infants can distinguish between displays of possible or impossible figures, which may require detection of inconsistent depth relations among local line junctions that disrupt global object configurations. Here, we used an eye-tracking paradigm to record eye movements in young infants during an object…

Gliga, Teodora; Elsabbagh, Mayada; Andravizou, Athina; Johnson, Mark – Infancy, 2009
Infant's face preferences have previously been assessed in displays containing 1 or 2 faces. Here we present 6-month-old infants with a complex visual array containing faces among multiple visual objects. Despite the competing objects, infants direct their first saccade toward faces more frequently than expected by chance (Experiment 1). The…

Amso, Dima; Johnson, Scott P. – Infancy, 2008
We examined changes in the efficiency of visual selection over the first postnatal year with an adapted version of a "spatial negative priming" paradigm. In this task, when a previously ignored location becomes the target to be selected, responses to it are impaired, providing a measure of visual selection. Oculomotor latencies to target selection…

Jeon, Hana; Moulson, Margaret C.; Fox, Nathan; Zeanah, Charles; Nelson, Charles A., III – Infancy, 2010
The current study examined the effects of institutionalization on the discrimination of facial expressions of emotion in three groups of 42-month-old children. One group consisted of children abandoned at birth who were randomly assigned to Care-as-Usual (institutional care) following a baseline assessment. Another group consisted of children…

Farroni, Teresa; Massaccesi, Stefano; Pividori, Donatella; Johnson, Mark H. – Infancy, 2004
Eye gaze has been shown to be an effective cue for directing attention in adults. Whether this ability operates from birth is unknown. Three experiments were carried out with 2- to 5-day-old newborns. The first experiment replicated the previous finding that newborns are able to discriminate between direct and averted gaze, and extended this…

Shaddy, D. Jill; Colombo, John – Infancy, 2004
This study examined 4- and 6-month-olds' responses to static or dynamic stimuli using behavioral and heart-rate-defined measures of attention. Infants looked longest to dynamic stimuli with an audio track and least to a static stimulus that was mute. Overall, look duration declined with age to the different stimuli. The amount of time spent in…
