Automatic Priming Effects for New Associations in Lexical Decision and Perceptual Identification
Information storage in semantic memory was investigated by looking at
automatic priming effects for new associations in two experiments. In
the study phase word pairs were presented in a paired-associate learning
task. Lexical decision and perceptual identification were used t
Evaluating the evidence for nonconscious processes in producing false memories:Reply to Gallo and Seamon
In response to the failure of Zeelenberg, Plomp, and Raaijmakers (2003) to replicate the results of Seamon, Luo, and Gallo (1998) regarding their purported finding of a reliable false memory effect in the absence of memory for the list items, Gallo and Seamon (2004) report a new experiment that they claim shows that conscious activation of a related lure during study is not necessary for its subsequent recognition. We critically evaluate their conclusion and argue that the evidence clearly shows that false recognition is critically dependent on the conscious recollection of one or more of the list items. Thus, this as well as the previous experiments show no evidence for nonconscious processes in producing false memories
Can false memories be created through nonconscious processes?
Presentation times of study words presented in the Deese/Roediger and McDermott (DRM) paradigm varied from 20 ms to 2000 ms per word in an attempt to replicate the false memory effect following extremely short presentations reported by J.G. Seamon, C.R. Luo and D.A. Gallo (1998). Both in a within-subjects design (Experiment 1) and in a between-subjects design (Experiment 2) subjects showed memory for studied words as well as a false memory effect for related critical lures in the 2000-ms condition. However, in the
Does pizza prime coin? Perceptual priming in lexical decision and pronunciation.
In 6 experiments the authors investigated priming for perceptually
related word pairs (i.e., words that refer to objects with the same
shape such as pizza-coin), trying to replicate earlier findings by R.
Schreuder et al (see record 1985-06198-001) while avoiding some of the
methodological problems that were present in that study. University
students participated in the experiments. Under standard conditions no
perceptual priming was obtained. However, in all experiments priming for
associated pairs was found. Only after activation tasks that focused on
perceptual features was priming for perceptually related word pairs
found in pronunciation. Perceptual priming was also obtained in lexical
decision after activation tasks, but only when strong associates were
not presented in the experiment. The results show that priming for
perceptually related word pairs is not a general finding
REMI and ROUSE: Quantitative Models for Long-Term and Short-Term Priming in Perceptual Identification
The REM model originally developed for recognition memory (Shiffrin & Steyvers, 1997) has recently been extended to implicit memory phenomena observed during threshold identification of words. We discuss two REM models based on Bayesian principles: a model for long-term priming (REMI; Schooler, Shiffrin, & Raaijmakers, 1999), and a model for short-term priming (ROUSE; Huber, Shiffrin, Lyle, & Ruys, in press). Although the identification tasks are the same, the basis for priming differs in the two models. In both paradigms we ask whether prior study merely reflects a bias to interpret ambiguous information in a certain manner, or instead leads to more efficient encoding. The observation of a ‘both-primed benefit’ in two-alternative forced-choice paradigms appears to show that both processes are present. However, the REMI model illustrates that the both-primed benefit
is not necessarily indicative of an increase in perceptual sensitivity but might be generated by a criterion bias. The ROUSE model demonstrates how the amount of attention paid to the prime, and the consequent effect upon decision making, may lead to the reversal of the normal short-term priming effect that is observed in certain conditions
