Further Evidence Concerning Scanning and Sampling Assumptions
Following extended training in a visual detection task, functions were determined for individual sUbjects relating latency of detection responses to number of redundant signal elements embedded in tachistoscopic displays of letters and to distance between signal elements. Latency proved invariant with respect to number of redundant signals and varied nonmonotonically with distance. Of the sever...
متن کاملSpasmodic Dysphonia: Evidence concerning a Neurological Cause
The term spasmodic dysphonia is a recent one, suggested by Aronson et al. (1968b), as a replacement for the term spastic dysphonia. The new term was advocated because "the term spastic is commonly used to imply disease of ... pyramidal pathways", while the neurological evidence in the Aronson research concerned the extrapyramidal system.

متن کاملEvidence concerning the medical management of caries.
Caries is an infectious, chronic and cumulative disease. It seriously affects quality of life and creates considerable expense for individuals and communities. The disease can be managed by acting on biofilm formation and maturation, by modifying the kinetics of apatite solution or with a combination of the two processes.

متن کاملGenetic evidence concerning the origins of South and North Ossetians.
Ossetians are a unique group in the Caucasus, in that they are the only ethnic group found on both the north and south slopes of the Caucasus, and moreover they speak an Indo-European language in contrast to their Caucasian-speaking neighbours. We analyzed mtDNA HV1 sequences, Y chromosome binary genetic markers, and Y chromosome short tandem repeat (Y-STR) variability in three North Ossetian g...
متن کاملThe Search for Evidence Concerning the Origin of Fish
A review of the fossil and taxonomic evidence for fish evolution is undertaken. No empirical evidence exists for their evolution from non-fish, even though 80% of all known fossils are marine animals, mostly various types of fish. Fully formed fish appeared very “early” in the fossil record, although numerous forms have become extinct. Many fish that are claimed to be multimillions of years old...
