In this reply to Salverda (2016), we address a critique of the claims made in our recent study of real-time processing of American Sign Language (ASL) signs using a novel visual world eye-tracking paradigm (Lieberman, Borovsky, Hatrak, & Mayberry, 2015). Salverda asserts that our data do not support our conclusion that native signers and…

Our previous work interpreted single-lognormal fits to inter-gaze distance (i.e., "gaze steps") histograms as evidence of multiplicativity and hence interactions across scales in visual cognition. Bogartz and Staub (2012) proposed that gaze steps are additively decomposable into fixations and saccades, matching the histograms better and…

Dr. Temple Grandin is a professor of animal sciences at Colorado State University where she conducts research and teaches courses on livestock handling and facility design. She is also a past member of the board of directors of the Autism Society of America. She lectures to parents and teachers throughout the United States on her experiences with…

In "The Renaissance Rediscovery of Linear Perspective," one of Samuel Edgerton's claims is that Filippo Brunelleschi and his contemporaries did not develop a three-dimensional style of representing the world in painting as much as they reappropriated a way to depict the natural world in painting that most mirrored the human perception of it.…

The next several pages are intended as a "Commentary" on the six target articles bundled together as a Special Issue of the "Journal of Cognition and Development"--literature reviews and research reports all intended to "build bridges" between the study of cognitive development in typical and atypical populations.

Recent results from Vo and Wolfe (2012b) suggest that the application of memory to visual search may be task specific: Previous experience searching for an object facilitated later search for that object, but object information acquired during a different task did not appear to transfer to search. The latter inference depended on evidence that a…

This petition is about two of the traditional three R's - reading, writing, and arithmetic; it concerns learning letter formation and learning to read, both of which require continuous interplay between the different perceptual attunements of central and paracentral areas of the retina. This interplay, managing the field of view between zooming-in…

White (2012) proposed that kinematic features in a visual percept are matched to stored representations containing information regarding forces (based on prior haptic experience) and that information in the matched, stored representations regarding forces is then incorporated into visual perception. Although some elements of White's (2012) account…

Bhatt and Quinn (2011) provide a compelling and comprehensive review of empirical evidence that supports the operation of principles of perceptual organization in young infants. They also have provided a comprehensive list of experiences that could serve to trigger the learning of at least some of these principles of perceptual organization, and…

The ultimate aim of artistic exploration is to explore the claim that objects are different from experience and beauty is just a by-product of the exploration. In other words, the truth in the eyes of each person may quite literally not be the same. This indicates that differences in the visual apparatus influence the viewing body's mastery of the…

Eye-trackers suitable for use with infants are now marketed by several commercial vendors. As eye-trackers become more prevalent in infancy research, there is the potential for users to be unaware of dangers lurking "under the hood" if they assume the eye-tracker introduces no errors in measuring infants' gaze. Moreover, the influx of voluminous…

In a recent critique Boles and Barth (2011) argue that their prior study investigating asymmetry/performance relationships (Boles, Barth, & Merrill, 2008) uncovered the "true" association (i.e., negative correlation) between lateralization of visual lexical processes and word recognition performance. They contend that our study reporting positive…

Bhatt and Quinn (2011) review the substantial evidence that learning constrains perceptual organization in infants. With those findings as a foundation, they discuss five kinds of experiences that engender learning in infants and propose that attention and unitization mediate infant learning. Bhatt and Quinn's article is informative--the ideas…

Skottun and Skoyles (2009) recently presented a comment on Vernier acuity and magnocellular dysfunctions in fragile X premutation carriers (Keri & Benedek, 2009). The authors concluded that our finding that the magnocellular deficit, as revealed by luminance-contrast sensitivity measurements, is associated with impaired Vernier acuity for…

Cognitive science research shows that the brain has two systems for processing visual information, one specialized for spatial information such as position, orientation, and trajectory, and the other specialized for information used to identify objects, such as color, shape and texture. Some individuals seem to be more facile with the spatial…
