Examined acuity thresholds for 1- and 2-month-old infants by presenting square wave gratings in a preference paradigm at four viewing distances. (Author/JMB)

Image size, viewing angle, and contrast affect performance of a visual discrimination task. Further, the three factors interaction in their effect on performance. (Author)

Assessed 14-week-olds' attention to green or red target objects moving in a field of distracting objects that varied in color. Found that infants' detection of green moving targets was masked in the presence of mixed red and green objects. Masking was not observed for red targets or for green targets in a field of green objects. (BC)

Extends the discussion of mimetic documents from labeled pictures and picture lists to labeled diagrams and diagram lists. Highlights how different mimetic documents provide qualitatively different levels of understanding. (RS)

Infants were habituated to reversible and nonreversible pictures of faces. The reversible picture depicted a different face when inverted 180 degrees. For the reversible picture, the infants devoted more visual attention to the inverted picture than to the original picture. (BC)

Shows how visual images and text differ from one another in the extent to which they resemble their referents; kinds of concepts they evoke; precision with which they evoke them; kinds of structures they impose on the information they convey; and degree to which that information can be interpreted by perceptual as opposed to higher level cognitive…

Presents examples of logotypes of the word "Mexico" by second-semester typography students from the Universidad de las Americas in Puebla, Mexico. Analyzes each according to its unity, coherence, and emphasis. Discusses the context, syntactic and semantic rhetorical figures, metaphor, and the denotation and connotation of each. (CR)

We present three experiments in which subjects were asked to make speeded sex judgements (Experiment 1) or semantic judgements (Sections 3 and 4) to face targets and nonface items, while ignoring a solitary flanking distractor face or a nonface stimulus. Distractors could be either congruent (same response category) or incongruent (different…

Four experiments evaluated the role of encoding-based and retrieval-based factors in the production of false recognition. The association of unusual fonts with study items, the match between study and test font, and the duration of retrieval time allotted to subjects to make recognition memory decisions were varied in order to examine the role…

Marx's call for a materialism capable of engaging reality as "sensuous human activity" opens a question about the role of representation in relation to data. Images have increasingly been seen as significant forms of data in the history of education. Derrida's theory of the spectre -- a variation on the positions established in his earlier works…

Despite a large body of research demonstrating the kinds of categories to which infants respond, few studies have directly assessed how infants' categorization unfolds over time. Four experiments used a visual familiarization task to evaluate 10-month-old infants' (N=98) learning of exemplars characterized by commonalities in appearance or…

We report the case of a 25-year-old healthy, blind male, MT, who experiences normal patterns of deja vu. The optical pathway delay theory of deja vu formation assumes that neuronal input from the optical pathways is necessary for the formation of the experience. Surprisingly, although the sensation of deja vu is known to be experienced by blind…

To the extent that all types of visual stimuli can be verbalized to some degree, verbal mediation is intrinsic in so-called ''visual'' memory processing. This impurity complicates the interpretation of visual memory performance, particularly in certain neurologically impaired populations (e.g., aphasia). The purpose of this study was to…

The relative efficacy with which appearance of a new object orients visual attention was investigated. At issue is whether the visual system treats onset as being of particular importance or only 1 of a number of stimulus events equally likely to summon attention. Using the 1-shot change detection paradigm, the authors compared detectability of…

A flashed stimulus is perceived as spatially lagging behind a moving stimulus when they are spatially aligned. When several elements are perceptually grouped into a unitary moving object, a flash presented at the leading edge of the moving stimulus suffers a larger spatial lag than a flash presented at the trailing edge (K. Watanabe. R. Nijhawan.…
