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.…

A sound presented in close temporal proximity to a visual stimulus can alter the perceived temporal dimensions of the visual stimulus (temporal ventriloquism). In this article, the authors demonstrate temporal ventriloquism in the flash-lag effect (FLE), a visual illusion in which a flash appears to lag relative to a moving object. In Experiment…

The relationship between luminance (i.e., the photometric intensity of light) and its perception (i.e., sensations of lightness or brightness) has long been a puzzle. In addition to the mystery of why these perceptual qualities do not scale with luminance in any simple way, "illusions" such as simultaneous brightness contrast, Mach bands,…

Participants judged whether two sequential visual events were presented for the "same" length of time or for "different" lengths of time, while ignoring two irrelevant sequential sounds. Sounds could be either the same or different in terms of their duration or their pitch. When the visual stimuli were in conflict with the sound stimuli (e.g.,…

We present a technique called Random Image Structure Evolution (RISE) for use in experimental investigations of high-level visual perception. Potential applications of RISE include the quantitative measurement of perceptual hysteresis and priming, the study of the neural substrates of object perception, and the assessment and detection of subtle…
