How does the concurrent use of language affect perception and memory for exemplars? Labels cue more general category information than a specific exemplar. Applying labels can affect the resulting memory for an exemplar. Here 3 alternative hypotheses are proposed for the role of labeling an exemplar at encoding: (a) labels distort memory toward the…

Many species, including humans, display group behavior. Thus, perceiving crowds may be important for social interaction and survival. Here, we provide the first evidence that humans use ensemble-coding mechanisms to perceive the behavior of a crowd of people with surprisingly high sensitivity. Observers estimated the headings of briefly presented…

Does a visual mask need to be perceptually present to disrupt processing? In the present research, we proposed to explore the link between perceptual and memory mechanisms by demonstrating that a typical sensory phenomenon (visual masking) can be replicated at a memory level. Experiment 1 highlighted an interference effect of a visual mask on the…

Perceptual simulations are unconscious and automatic, whereas perceptual imagery is conscious and deliberate, but it is unclear how easily one can transfer perceptual information from unconscious to conscious awareness. We investigated whether it is possible to be aware of what one is mentally representing; that is, whether it is possible to…

Caparos and Linnell (2009, 2010) used a variable-separation flanker paradigm to show that (a) when cognitive load is low, increasing perceptual load causes spatial attention to focus and (b) when perceptual load is high, decreasing cognitive load causes spatial attention to focus. Here, we tested whether the effects of perceptual and cognitive…

The substantial distractor interference obtained for small displays when the target appears alone is reduced in large displays when the target is embedded among neutral letters. This finding has been interpreted as reflecting low-load and high-load processing, respectively, thereby supporting the theory of perceptual load (Lavie & Tsal, 1994).…

M. Singh and B. L. Anderson proposed a perceptual theory of achromatic transparency in which the perceived transmittance of a perceived transparent filter is determined by the ratio of the Michelson contrast seen in the region of transparency to that of the background seen directly. Subsequently, B. L. Anderson, M. Singh, and J. Meng proposed that…

By age 2, children attribute referential mental states such as perceptions and emotions to themselves and others, yet it is not until age 4 that they attribute representational mental states such as beliefs. This raises an interesting question: is attribution of beliefs different from attribution of perceptions and emotions in terms of its neural…

Tested whether a verbal description given before or after presentation of a picture effected visual processing and/or memory. (SB)

Describes subjective-contour illusions and gives explanations for perception of shape and brightness in these figures. Supports cognitive mechanisms rather than psychological mechanisms. Gives examples of subjective-contour illusions and summarizes explanations of other psychologists with regard to this topic. (CW)

A model of mental representations is developed and shown to provide a framework for interpreting research. The content of awareness is characterized as a model of the world capable of simulating future events, anticipating present events, and thereby formulating appropriate actions. Properties of awareness and of underlying processes are…

Reviews the literature dealing with the loci and parameters of visual selective attention. It is maintained that input selection can be found at several points in the course of processing. Specifically, a case is made for very early perceptual selection, called perceptual tuning, which can be based on higher-order conceptual or structural stimulus…

THE PROBLEM OF THE RESEARCH WAS TO STUDY THE RELATIONSHIP BETWEEN PERCEPTION AND COGNITION FACTORS IN THE GROWING CHILD. A CENTRAL TASK WAS TO DEVELOP AN INSTRUMENT FOR ASSESSING THE DEVELOPMENT OF SIZE CONSTANCY IN A PROCEDURE IN WHICH THE EFFECTS OF COGNITIVE ACTIVITY COULD BE EITHER CONTROLLED OR EVALUATED. USING A NUMBER OF CONSIDERATIONS, THE…

Reports the findings of experiments that suggest that much of perception, even to high interpretive levels, is automatic and independent of intention or consciousness, and that the production of words in reading may involve problems that have nothing to do with articulation, even if the words have been identified.

The results suggested that profoundly retarded children do show habituation and dishabituation to visual stimuli and are actively storing and processing information about their perceptual world. (Author/DLS)
