Shuwairi, Sarah M. – Journal of Experimental Child Psychology, 2009
Can infants use interposition and line junction cues to infer three-dimensional (3D) structure? Previous work has shown that in a task that required 4-month-olds to discriminate between static two-dimensional (2D) pictures of possible and impossible cubes, infants exhibited a spontaneous preference for displays of the impossible cube but left open…

Kravitz, Dwight Jacob; Behrmann, Marlene – Journal of Experimental Psychology: Human Perception and Performance, 2008
Although object-based attention enhances perceptual processing of information appearing within the boundaries of a selected object, little is known about the consequences for information in the object's surround. The authors show that distance from an attended object's center of mass determines reaction time (RT) to targets in the surround. Of 2…

Ganon, Ellen C.; Swartz, Karyl B. – Journal of Experimental Child Psychology, 1980
Results suggest that when the internal element of a compound stimulus is a highly preferred or salient stimulus, young infants will process information about its characteristics. (Author/DB)

Gellatly, Angus; Pilling, Michael; Cole, Geoff; Skarratt, Paul – Journal of Experimental Psychology: Human Perception and Performance, 2006
Object substitution masking (OSM) is said to occur when a perceptual object is hypothesized that is mismatched by subsequent sensory evidence, leading to a new hypothesized object being substituted for the first. For example, when a brief target is accompanied by a longer lasting display of nonoverlapping mask elements, reporting of target…

Strother, Lars; Kubovy, Michael – Journal of Experimental Psychology: Human Perception and Performance, 2006
The authors conducted 3 experiments to explore the roles of curvature, density, and relative proximity in the perceptual organization of ambiguous dot patterns. To this end, they developed a new family of regular dot patterns that tend to be perceptually grouped into parallel contours, dot-sampled structured grids (DSGs). DSGs are similar to the…

Maurer, Daphne; and Adams, Russell J. – Journal of Experimental Child Psychology, 1987
Two different methods which minimize achromatic cues were used to test the ability of one-month-olds to discriminate gray from broadband blue. Test data imply an improvement between birth and one month of age in the discrimination of gray from broadband blue. Possible physiological changes underlying this improvement are discussed.

Chapman, Michael – Journal of Experimental Child Psychology, 1981
The hypothesis that perceptual development proceeds from less to greater dimensional separability was tested by giving a speeded classification task to first and fourth graders. Results supported the hypothesis that development proceeds toward greater flexibility of attention rather than simply toward increasing separability. (Author/DB)

Bornstein, Marc H.; Krinsky, Sharon J. – Journal of Experimental Child Psychology, 1985
Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Slater, Alan; And Others – Journal of Experimental Child Psychology, 1985
Three experiments are described which relate to models of infant visual preferences and to the ways in which preferences can be modified or created by habituation. Results suggest that the Banks and Salapatek's contrast sensitivity model can be a powerful predictor of preferential looking in newborns and that preferences based on experience can be…

Smothergill, Daniel W.; Kraut, Alan G. – Merrill-Palmer Quarterly, 1980
The purpose of this paper is to set out a descriptive model in which the relative dominance of a stimulus dimension is related to the form of attention it receives. (Author/DB)

Coldren, Jeffrey T.; Colombo, John – Monographs of the Society for Research in Child Development, 1994
In three experiments, nine-month-old infants were trained to fixate on a particular feature in a pair of stimuli that varied along three dimensions. In a fourth experiment, infants were trained to fixate on a stimulus compound until reaching a learning criterion. Infants' discrimination learning under these conditions implied an ability to attend…

Slater, Alan; And Others – Journal of Experimental Child Psychology, 1991
Tested infants' remembrance of the orientations and angular relations of line segments. In one experiment, infants "dishabituated" to a change in orientation but not a change in angle. In two further experiments, infants familiar with either an acute or obtuse angle gave strong novelty preferences to a different angle. (BC)

Vogel, Edward K.; Woodman, Geoffrey F.; Luck, Steven J. – Journal of Experimental Psychology: Human Perception and Performance, 2006
How long does it take to form a durable representation in visual working memory? Several theorists have proposed that this consolidation process is very slow. Here, we measured the time course of consolidation. Observers performed a change-detection task for colored squares, and shortly after the presentation of the first array, pattern masks were…

Walker, Jearl – Scientific American, 1986
Describes experiments which focus on the perception of three dimensions. Discusses the cues about distance and depth and the role they have in perceptions of three dimensions. Evaluates the effect of color on the illusion on depth. (ML)

Colombo, John; And Others – Cognitive Development, 1995
Investigates the dominance of global versus local visual properties in four-month-old infants as a function of individual differences in fixation duration. Suggests that long-looking infants process visual information more slowly than short-looking infants, and there may be qualitative differences in the manner in which the two groups of infants…
