Recognition memory for faces is hampered much more by inverted presentation than is memory for any other material so far examined. The present study demonstrates that faces are not unique with regard to this vulnerability to inversion. The experiments also attempt to isolate the source of the inversion effect. In one experiment, use of stimuli (landscapes)(More)
Adult face recognition is severely hampered by stimulus inversion. Several investigators have attributed this vulnerability to the effect of orientation on encoding relational aspects of faces. Previous work has also demonstrated that children are less sensitive to orientation of faces than are adults. This has been interpreted as reflecting an increasing(More)
The existence of a right hemisphere capacity, specific to upright faces was investigated. Upright and inverted faces, equally complex as patterns, were presented under lateralized tachistoscopic conditions to two groups of normal adult subjects. A significant orientation by visual field advantage was found. While there was a highly significant left visual(More)
Asymptomatic persons at risk for Huntington's disease (HD) (N = 28) were assessed with neuropsychological, psychiatric, and neurologic tests while undergoing genetic linkage studies to determine their probability of carrying the HD gene. Those participants who were subsequently identified as probable gene carriers did not differ on neurologic or psychiatric(More)
Performance on the Neurobehavioral Evaluation System (NES) has been demonstrated to be affected by exposure to a variety of neurotoxicants. However, the relation of NES subtests to CNS function has not yet been documented in patients diagnosed with neurologic disorders known to implicate specific brain substrates. A validation study of the NES2 was carried(More)
Visually naïve kittens turn their eyes toward visual targets but lack other visual-motor coordinations. Light-reared animals were able to mediate guided behaviors with an immobilized eye, but animals with the eye immobilized before initial exposure to a lighted environment were not. Eye movement is implied to play an essential role in visual-motor(More)
