The seven articles of this special issue showcase the continuing intellectual legacy of Amos Tversky (1937-1996) in cognitive psychology. Tversky made fundamental contributions to many areas, including decision making, belief revision, and judgments of similarity. These papers are by some of his recent students. (SLD)

Using object pairs that varied orthogonally in alignability and thematic relatedness, 3 experiments involving 242 college students highlight the importance of compatibility between stimuli and processing in affecting task outcomes. Certain types of stimuli are more conducive to one type of processing than another. (SLD)

Four major types of interaction of stimulus dimensions based on perceptual research are described: integral, configural, separable, and asymmetric separable. Implications of these interactions for concept and choice processes are discussed. (Author/DEP)

Eight experiments involving 99 college students examined the role of edge-assignment in a contour matching task. Edge-matching performance was not based solely on a raw description of the edges themselves. Results suggest a pervasive tendency within the visual system to go beyond the edges toward figural shapes. (SLD)

Results of a study with 48 Israeli college students cast doubt on feature integration theory. Subjects searching for a probe in an array of three stimuli in two attention conditions, attention being manipulated by a dual-task requirement, made more conjunction errors than feature errors. (SLD)

It is proposed that there is a modular but interconnected system underlying the perceived hierarchical organization of objects. The discussion centers on neural and cognitive mechanisms of organizing objects within objects in at least four separate subsystems. (SLD)

Eliminative connectionism as a theory of how humans generalize universal relationships to unfamiliar instances cannot account for the way universals are extended to arbitrary items. The discussion shows that the class of eliminative connectionist models currently in vogue cannot extend universals outside the training space. (SLD)

Studied task switching in 4 experiments involving 111 Israeli undergraduates. Results show the preparation for a task switch is not a by-product of general preparation by phasic alertness or predicting target onset and establish reconfiguration as a separate preparatory process. Suggests that there are at least three components of task switching…

Used a dual-task method to study the processes that underlie the flexible conjunction of information. Results of four experiments, involving 16, 36, 12, and 16 college students and adults suggest that flexible spatial memory depends on the ability to combine diverse information sources rapidly into unitary representations. (SLD)

Although a verbal intelligence test is directly a measure of what people know, it is indirectly a way of identifying people who can code and manipulate verbal stimuli rapidly in situations in which knowledge per se is not a major factor. (Author/BJG)

A cued recall procedure was employed to assess the effectiveness of implicit and explicit word prompts for sentence memory in children. The implicit cues were much less effective than the explicit cues for 6-7 year olds while the cue types did not differ for 11-12 year olds. (Author/DEP)

Studied how nonnatural entities are represented by examining concepts of God of 145 college students in three experiments. In story processing tasks, students often used an anthropomorphic God concept that was inconsistent with their stated theological beliefs. The tendency to anthropomorphize may be generalizable to other agents. (SLD)

Experiments involving a total of 114 college students from Indiana and Israel demonstrate that the initial analysis of visual objects into features from different dimensions strongly constrains postperceptual processes of response selection. A model of response selection is proposed to account for the findings. (SLD)

A reminding-based generalization view of category learning was studied in 4 experiments involving a total of 247 college students. Experiments demonstrated that categorization by reminding can affect what is learned about the category and later categorization performance. Implications of the results for category learning are discussed. (SLD)
