The fidelity of visual and auditory memory

Psychonomic Bulletin & Review - Recent studies show that recognition memory for pictures is consistently better than recognition memory for sounds. The purpose of this experiment was to compare...     

Category-specific naming impairments? Yes

Recently, Stewart, Parkin, and Hunkin (1992) have questioned previously reported cases of selective damage in processing items from categories of animate objects, arguing that there has been a lack of adequate control for visual familiarity, visual complexity, and name frequency of the stimuli employed. When re-testing Michelangelo (see Sartori & Job, 1988), one of the patients cited by Stewart et al. (1992), with a set of materials matched on all three factors, the asymmetry in naming animal and artefact items still remains. An analogous pattern is obtained when--in addition to such factors--the visual similarity within the sub-sets of animals and artefacts is taken into account. These results constitute empirical evidence for category-specific impairments and cannot be interpreted as being due to isolated or conjoint effects of visual familiarity, visual complexity, or name frequency.     

Idea‐Generation in Naturally Occurring Contexts

This study examined naturally occurring idea‐generation in organizational groups completing an extended problem‐solving task. Meetings held by 11 groups engaged in a quality improvement process in a governmental agency were analyzed to identify 37 idea‐generation episodes. All groups had available a group decision support system (GDSS), although some opted not to use it. Across all groups, idea productivity was low though fairly efficient, but GDSS‐supported idea‐generation produced significantly fewer ideas. In general, idea‐generation as a process appears to be more complex than has been thought; observed deviations from idealized idea‐generation norms were not necessarily dysfunctional. The findings encourage reassessment of the assumptions underlying existing normative models of idea‐generation.     

Sex Bias in Educational-Vocational Counseling

Literature pertinent to sex discrimination in educational and vocational counseling is reviewed. Among the many factors that contribute to inequitable counseling are the sex role socialization that clients bring to the counseling interaction, the sex role attitudes and biases of counselors, deficiencies in counselor training, and shortcomings of tests and other source materials used in counseling practice. Recommendations are made toward more comprehensive counseling services for women and men.     

Emergence and structural properties

Synthese - I present in this article a new theory of structural properties or, more precisely, of structural kinds, such as being methane. According to this theory, structural kinds are kinds that...
