Visual scanpath recording was used to investigate the information processing strategies used by a prosopagnosic patient, SC, when viewing faces. Compared to controls, SC showed an aberrant pattern of scanning, directing attention away from the internal configuration of facial features (eyes, nose) towards peripheral regions (hair, forehead) of the…

Evidence from human cognitive neuroscience, animal neurophysiology, and behavioral research demonstrates that human adults, infants, and children share a common nonverbal quantity processing system with nonhuman animals. This system appears to represent both discrete and continuous quantity, but the proper characterization of the relationship…

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…

Thirty elementary school students were assigned to one of three experimental conditions, (labeling, imagery, or control) in a pattern reproduction task. (ST)

An experiment using a computer to assign content designators to unedited machine readable bibliographic data to create MARC records is described. (Author)

All mathematical feature selection techniques can be classified into one of two major categories--feature selection in the measurement space and feature selection in the transformed space. This article discusses the various feature selection techniques in the light of this two-category classification. (Author/HB)

A theoretica l approach to the problem of converting printed bibliographic records to machine readable form is developed based on principles of systems analysis. (Author)

Presented is experimental evidence that humans develop strong preferences for objects that become familiar through repeated exposure, even when the exposures are so degraded that they cannot be discriminated as stimuli previously seen. Implications are made regarding other studies where affective discriminations are made with very little stimulus…

Adults listened to a list containing 30 words that were repeated from zero to seven times each. Subjects were tested for sensitivity to differences in frequency of occurrence. All were equally sensitive to frequency information. Prior knowledge about the nature of the test did not affect performance. (Author)

This unclassified-unlimited bibliography contains 183 references, with abstracts, dealing specifically with optical or graphic information processing. Citations are grouped under three headings: display devices and theory, character recognition, and pattern recognition. Within each group, they are arranged in accession number (AD-number) sequence.…

Results were interpreted in terms of current conceptions of age differences in information-processing speed. (Author)

The abstracts obtained so far are of sufficiently good quality to indicate that large-scale testing of the methods of the automatic abstracting system is warranted. (Author/MM)

This study examines the integration of heterogeneous bibliographic information resources from geographically distributed locations in an automated, unified, and controlled way using abstract data types called "classes" through the Message-Object Model defined in Smalltalk-80 software. The concept of achieving data consistency by…

The similarity match took longer than the identity match, and the difference in latency increased as the number of lines in the pattern increased. (Author)
