Havy, Mélanie; Zesiger, Pascal E. – Developmental Science, 2021
From the very first moments of their lives, infants selectively attend to the visible orofacial movements of their social partners and apply their exquisite speech perception skills to the service of lexical learning. Here we explore how early bilingual experience modulates children's ability to use visible speech as they form new lexical…

Erin M. Anderson; Susan J. Hespos; Lance J. Rips – Grantee Submission, 2018
Infants fail to represent quantities of non-cohesive substances in paradigms where they succeed with solid objects. Some investigators have interpreted these results as evidence that infants do not yet have representations for substances. More recent research, however, shows that 5-month-old infants expect objects and substances to behave and…

Olofson, Eric L.; Baldwin, Dare – Cognition, 2011
We investigated infants' ability to recognize the similarity between observed and implied goals when actions differed in surface-level motion details. In two experiments, 10- to 12-month-olds were habituated to an actor manipulating an object and then shown test actions in which the actor contacted the object with a novel hand configuration that…

Lewkowicz, David J. – Developmental Psychology, 2010
Three experiments investigated perception of audio-visual (A-V) speech synchrony in 4- to 10-month-old infants. Experiments 1 and 2 used a convergent-operations approach by habituating infants to an audiovisually synchronous syllable (Experiment 1) and then testing for detection of increasing degrees of A-V asynchrony (366, 500, and 666 ms) or by…

Smitsman, Ad W.; Dejonckheere, Peter J. N.; De Wit, Tessa C. J. – Developmental Psychology, 2009
Four experiments familiarized 6-, 9-, 12-, and 16-month-old infants to a solid block that was repeatedly lowered into a semitransparent container. In test trials the end state, containment, was either compatible or incompatible with the objects' size and position. In Experiment 1, infants saw the block and box successively before they observed the…

Iverson, Jana M.; Hall, Amanda J.; Nickel, Lindsay; Wozniak, Robert H. – Brain and Language, 2007
This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles…

Gregg, Melissa K.; Samuel, Arthur G. – Journal of Experimental Psychology: Human Perception and Performance, 2008
Change blindness, or the failure to detect (often large) changes to visual scenes, has been demonstrated in a variety of different situations. Failures to detect auditory changes are far less studied, and thus little is known about the nature of change deafness. Five experiments were conducted to explore the processes involved in change deafness…

Fontenelle, Sarah A.; Kahrs, Bjorn Alexander; Neal, S. Ashley; Newton, A. Taylor; Lockman, Jeffrey J. – Journal of Experimental Child Psychology, 2007
Everyday environments, even small regions within reach, vary dramatically in terms of material composition. Adapting one's manual behavior to such transitions can be considered to be an important element of skilled action. To investigate the origins of this ability, we presented 8-month-olds (n=24) and 10-month-olds (n=24) hard or soft objects on…

Yonas, Albert; And Others – Child Development, 1987
A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

Dodwell, P. C.; And Others – Science, 1976
Reports the results of studies of perception of very young infants. Sixty infants 6 to 23 days old were presented objects; looking-at and reaching-for the objects were measured. Results indicated active visual exploration of objects did occur; however, little motor activity was directed toward the objects. (SL)

Johnson, Scott P.; Mason, Uschi – Child Development, 2002
Examined 2-month-old infants' perception of sparse random-dot displays depicting an illusory shape against a background in three experiments in which background texture, luminance cues, and relative motion information were added or deleted. Found that infants preferred novel stimuli in each condition, revealing an early capacity to perceive shape…

Richards, John E.; Rader, Nancy – Journal of Experimental Psychology: Human Perception and Performance, 1981
Two experiments tested the effects of crawling-onset age, amount of crawling experience, and testing age on avoidance of the deep side of a visual cliff apparatus by human infants. Crawling-onset age disciminated between infants because crawling during the tactile phase interferes with later visual control of locomotion. (Author/RD)

Gibson, Eleanor; And Others – 1977
This experiment asked whether infants at 5 months perceived an invariant over four types of rigid motion (perspective transformations), and thereby differentiated rigid motion from deformation. Four perspective transformations of a sponge rubber object (rotation around the vertical axis, rotation around the horizontal axis, rotation in the frontal…

Bushnell, Emily W.; And Others – Child Development, 1995
Examined the ability of 1-year olds to remember the location of nonvisible targets. Found that infants were able to associate a nonvisible target with a direct landmark and to code its distance and direction with respect to themselves or the larger framework. Difficulty of coding with indirect landmarks was associated with cognitive complexity and…

Blanksby, D. C.; Langford, P. E. – Journal of Visual Impairment and Blindness, 1993
This article describes a visual assessment procedure (VAP) which evaluates capacity, attention, and processing (CAP) of infants and preschool children with visual impairments. The two-level battery considers, first, visual capacity and basic visual attention and, second, visual perceptual and cognitive abilities. A theoretical analysis of the…
