Using a crossover recognition memory testing paradigm, we tested whether the effects on face recognition of the memorability component of face typicality (Vokey & Read, 1992, 1995) are due primarily to the encoding process occurring during study or to the retrieval process occurring at test. At study, faces were either veridical in form or at moderate (Experiment 1) or extreme (Experiment 2) levels of caricature. The variable of degree of facial caricature at study was crossed with the degree of caricature at test. The primary contribution of increased memorability to increased hit rate was through increased distinctiveness at study. Increased distinctiveness at test contributed to substantial reductions in the false alarm rate, too. Signal detection analyses confirmed that the mirror effects obtained were primarily stimulus/memory-based, rather than decision-based. Contrary to the conclusion of Vokey and Read (1992), we found that increments in face memorability produced increments in face recognition that were due at least as much to enhanced encoding of studied faces as they were to increased rejection of distractor faces. 相似文献

Sensory adaptation and visual aftereffects have long given insight into the neural codes underlying basic dimensions of visual perception. Recently discovered perceptual adaptation effects for complex shapes like faces can offer similar insight into high-level visual representations. In the experiments reported here, we demonstrated first that face adaptation transfers across a substantial change in viewpoint and that this transfer occurs via processes unlikely to be specific to faces. Next, we probed the visual codes underlying face recognition using face morphs that varied selectively in reflectance or shape. Adaptation to these morphs affected the perception of "opposite" faces both from the same viewpoint and from a different viewpoint. These results are consistent with high-level face representations that pool local shape and reflectance patterns into configurations that specify facial appearance over a range of three-dimensional viewpoints. These findings have implications for computational models of face recognition and for competing neural theories of face and object recognition. 相似文献

In 3 experiments, participants, on signal, moved a cursor from a central position to 1 of 8 numerically labeled locations on the circumference of a clock face. Movements were controlled by a mouse in 1 of 4 conditions: vertical reversal, horizontal reversal, combined reversals, or normal (i.e., no reversals). Participants were trained in 1, 2, or 3 of these conditions and were tested 1 week later with either the same or a different condition. There were improvements across training and perfect retention across the delay. There was little or no transfer, however, even when training involved combined reversals or multiple conditions. These results illustrate severe specificity of training and are interpreted in terms of acquired inhibition of normal responses. 相似文献

Students entering (N = 1,134) the U.S. Naval Academy class of 2000 were administered the Kirton Adaption-Innovation Inventory on the first day of Plebe Summer, a 7-wk. nonacademic training program completed by all entering students in the summer prior to the freshman year. The mean score on Innovation cognitive style for this sample of plebes was approximately a standard deviation lower than those of five other undergraduate student samples from nonmilitary universities. Furthermore, the 98 plebes who voluntarily withdrew before completing the program scored higher on the average on Innovation than those who remained. Findings suggest that, in terms of Person-Organization fit, plebes with a more innovative cognitive style may, perhaps, be less compatible with the regimentation-style climate of the Academy than those with an Adaptive cognitive style. Further research, however, is needed to specify the relationship between Academy students' cognitive style and other important organizational outcomes. 相似文献

English contains many nominals that would be absent in Chinese because Chinese makes greater use of zero anaphora, which is an empty grammatical slot in a sentence standing for a previously mentioned referent. Native Chinese and native English speakers were compared in comprehending modified English passages from a standardized reading test with nominals deleted that would be absent in Chinese. In three experiments, Chinese speakers showed superior comprehension as measured by objective multiple-choice questions in this case, but not when no words were deleted or when nominals were deleted that would not be absent in Chinese. These results imply that native Chinese speakers develop reference tracking strategies that they transfer to comprehending English.This research was supported in part by United States Army Research Institute Contracts MDA903-93-K-0010, DASW01-96-K-0010, DASW01-99-K-0002, and DASW01-03-K-0002 to the University of Colorado (Alice Healy, Principal Investigator).We thank Lyle Bourne and Barbara Fox for stimulating discussions about this research.

This study provides evidence of stereotype threat in men on a test of a feminine ability called social sensitivity, that is, the ability to decode nonverbal cues. Men who were told that the test assessed social sensitivity and produced better scores for women than men performed worse on the test than did men who were told that the test assessed information processing. Because social sensitivity can be an automatic skill and stereotype threat uses mental capacity, this effect was moderated by self-reported strategy usage. Mens performance worsened in the threat condition only when they reported more deliberative and less intuitive strategies for decoding nonverbal cues. 相似文献
