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)
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)
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)
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)
We describe our entanglement in the controversial public issue of subliminal messages in advertising and popular music in order to provide a report of our research unencumbered by the misrepresentations in the various media reports of this work. A distinction is drawn between the allegedpresence of these messages in the media concerned and the impact they(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)
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)
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)
Following neural network simulations of the two experiments of, argued that the opposition logic advocated by was incapable of distinguishing between single and multiple influences on performance of artificial grammar learning and more generally. We show that their simulations do not support their conclusions. We also provide different neural network(More)
Following Brooks and Vokey (1991), we show that positive transfer to new items generated from an artificial grammar in which the vocabulary has been changed from training to test can be based on "abstract analogy" to specific training items (specific similarity) rather than abstraction of a grammar and symbol remapping rules, even with remapping unique to(More)
