摘要：This investigation was an attempt to evaluate the effectiveness of an electronic obstacle-detecting (O/D) device for the blind. Ss [subjects] were 26 totally blind individuals. Three series of training sessions on the O/D were conducted. Performance was assessed in 1 pretraining session with the customary mode of travel a*d 3 posttraining sessions with the O/D. Ss were also given several psychological tests and 2 interviews. Using the O/D on a standard obstacle course, Ss took longer to walk t...

摘要：Solutions of 1000 and 2000 ppm (mg. per liter) of Na2SO4, NaHCO3, CaSO4, MgSO4, NaCl, CaCl2, and Na2CO3 were rated on an acceptability scale in 3 separate studies. Results showed that the minerals ranked acceptability approximately as listed. Implications of the findings were discussed mainly in regard to detection thresholds for the 8 minerals and consumer-acceptance of naturally mineralized ground waters used for domestic supplies.

摘要：Using a compression chamber, Kiessling and Maag (1962) showed a decline in manual dexterity at a pressure simulating 100 ft. of water. Impairment was slight (7.9%) and was assumed to be of little practical importance. The present study examines this conclusion by testing divers in the water. The manual dexterity and tactile sensitivity of 12 free divers were tested above the surface, and at 10 and 100 ft. below the surface. The dexterity test took 28% longer at 10 ft. and 49% longer at 100 ft....
