Typical faces are more poorly discriminated on tests of recognition than are atypical faces, an effect suggested to mediate similar findings for attractive or likable faces. We tested the hypothesis that the effect of typicality on recognition is a function of context-free familiarity and memorability, which function in opposition. Two orthogonal principal(More)
Evidence for unconscious learning has typically been based on dissociations between direct and indirect tests of learning. Because of some inherent problems with dissociation logic, we applied the logic of opposition to 2 artificial grammar learning experiments. In Experiment 1, participants were exposed to 2 different sets of letter strings, generated from(More)
Higham and Vokey (2000, Exps.1 & 3)demonstrated that a slight increase in the display duration of a briefly presented word prior to displaying it in the clear for a recognition response increased the bias to respond "old". In the current research, three experiments investigated the phenomenology associated with this illusion of memory using the standard(More)
The consistent, but often wrong, impressions people form of the size of unseen speakers are not random but rather point to a consistent misattribution bias, one that the advertising, broadcasting, and entertainment industries also routinely exploit. The authors report 3 experiments examining the perceptual basis of this bias. The results indicate that,(More)
In three experiments, the effect of identification of a briefly presented word (prime) on a subsequent recognition response to that word (target) was investigated. Theories of current processing fluency (e.g., Jacoby & Whitehouse, 1989) suggest that prime identification should reduce P(old) relative to prime misidentification because awareness of the prime(More)
Perruchet (1994) suggested that "neither a specific-item retrieval process nor abstractive capacity" is required to explain Vokey and Brooks (1992) results, which instead can be accounted for in terms of knowledge of item fragments. The literature contains 2 definitions of abstractive. Rejecting abstractive in the sense of nonliteral units requires(More)
The deliberate application of a strategy can have unintended discriminative effects. It is argued that these effects or influences on discriminative responding are the source of automatic influences and can be dissociated from controlled influences under appropriate circumstances. Such automatic influences are often latent in the interaction between the(More)
For a century, the matching of images of fingerprints has been used for forensic identification. Despite that history, there have been no published, peer-reviewed studies directly examining the extent to which people can correctly match fingerprints to one another. The results of three experiments using naïve undergraduates to match images of fingerprints(More)
The male-offspring biased visual kin recognition in chimpanzees (Pan troglodytes) reported by L. A. Parr and F. B. M. de Waal (1999) was replicated with human (Homo sapiens) participants and a principal components analysis (PCA) of pixel maps of the chimpanzee face photos. With the same original materials and methods, both humans and the PCA produced the(More)
