The proper placement of uniform connectedness

In this journal, Palmer and Rock (1994) articulated a principle of perceptual organization calleduniform connectedness (UC); and they contended that previous investigators of perception had failed to realize the need for this organizing principle. The authors outlined a theory of perceptual organization that “places the principle of UC at center stage” (p. 38) in that UC was assigned the two privileged roles of (1) forming the fundamental units for later perceptual processes, and (2) yielding the postconstancy regions that correspond to environmental surfaces. In this commentary, I argue that the proposed theory entails a serial ordering of perceptual processes that is inconsistent with current evidence regarding figure-ground organization, stereo fusion, and object recogntion. In addition, I point out that Kurt Koffka (1935) recognized the need for a principle of unit formation similar to the one proposed by Palmer and Rock.

Gestural impairment and gestural ability in aphasia: A review

Studies of gestural ability in aphasic subjects have found impairment of gestural expression and comprehension, with a close relationship between severity of aphasia and degree of gestural impairment. A few investigators have correlated gestural ability with specific language functions or subcategories of aphasia. Reading appears to correlate better with gestural recognition than does auditory comprehension. Despite the general findings of gestural impairment in aphasia, successes have been reported with gestural training including artificial language techniques, pantomime, Amerind, and American Sign Language. Future studies of gestural therapy in aphasia should examine specific language deficits in order to identify those aphasic individuals who can benefit from gestural training.     

EMPIRICALLY DERIVED INJURY PREVENTION RULES

This study describes a set of empirically derived safety rules that if followed, would have prevented the occurrence of minor injuries. Epidemiologists have criticized behavioral interventions as increasing “safe” behavior but failing to demonstrate a decrease in injury. The present study documents retrospectively the link between safe behavior and injury. It demonstrates that these empirically derived rules are very similar to rules for the prevention of serious injury. The study also shows that these rules are not widely accepted and implemented by parents. Suggestions for future research in this area are advanced.     

Complexly fractionated syllogistic quantifiers

Consider syllogisms in which fraction (percentage) quantifiers are permitted in addition to universal and particular quantifiers, and then include further quantifiers which are modifications of such fractions (such as “almost 1/2 the S are P” and “Much more than 1/2 the S are P”). Could a syllogistic system containing such additional categorical forms be coherent? Thompson's attempt (1986) to give rules for determining validity of such syllogisms has failed; cf. Carnes &; Peterson (forthcoming) for proofs of the unsoundness and incompleteness of Thompson's rules. Building on Peterson (1985), the coherence of such a syllogistic can, however, be demonstrated with an algebra which provides its semantics; e.g., “almost 1/2 the S are P” is represented as “?(3(SP)?SP)”.     

Threat and authoritarianism in the United States, 1978-1987

Studies at both the individual and collective levels have implicated threat as an important factor in authoritarianism. As a follow-up to Sales's (1973) study relating behavioral indicators of authoritarianism to levels of social threat, the present research analyzed archival data from the United States for high-threat (1978-1982) and low-threat (1983-1987) periods. Societal measures of most attitude and behavioral components of the authoritarian syndrome significantly decreased between the high-threat and the low-threat periods. These results support the threat-authoritarianism relationship but also suggest a more complicated theoretical model that links perceived social conditions, arousal of authoritarian sentiments, dispositional authoritarianism, and the nature of political appeals--particularly those that engage authoritarian aggression.
