• How the Fan Effect has its Impact in SAC

  The result that there can be interference among competing associations to a concept has been known for many years, but its applicability in various contexts is not well understood. A number of theorists were puzzled by what was called the "Paradox of the Expert" - the implication that experts should be slower to answer questions about their specialty if knowing more slows one down - Certainly that is not true; however, the phenomenon of the slowing of verification to questions whose concepts are associated with more facts, even highly organized sets of facts, can be demonstrated. The research described here attempted to resolve this paradox, explaining when interference would occur, when it would not and why experts appear not to suffer from such interference. This work also has connections to other work on strategy selection. We have begun exploring how the fan effect can explain the word frequency mirror effect (Reder et al., 2000, 2002; Cary & Reder, 2003) and contextual effects in memory such as matching font of the word from study to test (Reder, Donavos, & Erickson, 2002). The font fan effect also produces a mirror effect (Diana, Peterson, & Reder, 2004). We have also begun extending this effect of contextual fan to face recognition (Diana & Reder, 2002).

Midazolam is a benzodiazepine that is used routinely as a sedative during surgery. It causes temporary anterograde amnesia and when subjects are under the effects of the drug (at a modest dose of .03mg/kg of body weight), they typically forget much of the information that is presented to them. The effects of midazolam are short lived in comparison to other benzodiazepines, with amnestic effects having dissipated substantially at one hour after IV administration. We are currently using midazolam to examine implicit, explicit, and working memory, explore the mechanisms of interference, and understand the relationship between structure and function in the brain.

Another project in the lab integrates my interests in skill learning and strategy choice. This work has led us to try to understand performance in an artificial air traffic controller task (funded by Office of Naval Research). The goals are to determine:

• the strategies used initially and with more expert performance

• how and when subjects shift their use of one strategy to another

• whether there are individual differences in performance under cognitive load and in sensitivity to the shifting characteristics of the task

• whether people vary in their sensitivity to shifting base rates in terms of the speed with which they alter their strategies

In the 1980s, I discovered that subjects could quickly adapt the strategy that they were using to answer questions based on a shift in the base rate of the likelihood that a particular strategy would be useful, specifically a retrieval strategy or an inference/reasoning strategy. What I found more surprising is that although subjects were strongly affected by the shifting base rates, they were unaware of these base rates or the strategies that they were employing (they assumed that they always tried to search for the answer first). Since that time, we have found this same result, that subjects can quickly shift strategies to changing base rates in many other domains. We have also found that subjects are oblivious to the strategies they are using or these base rates.

From this pattern of results, I have concluded that much of our strategy selection (or what is sometimes called our metacognition) occurs implicitly or without awareness.

Whether a person searches memory for the answer to a question, decides to deduce or induce the answer, or just responds "I don't know" without resorting to any other question answering strategy depends in part on whether the question and topic seems familiar. Some of my research has indicated that a very rapid feeling of knowing judgment influences an early evaluation of a question that gates the strategy selection to either attempt retrieval, try an alternative strategy, or give up. This view was considered implausible when first proposed. The dominant view at the time was that feeling of knowing the answer was determined by partial products from an early effort at retrieval of the answer. That is, the conventional wisdom, until recently, postulated that a person always tries to search for the answer before trying any other question-answering strategy.

• Role of Elaboration in retention of information

  This line of research provides support for the position that elaborations, when generated by the learner, facilitate learning and retention; however, author provided elaborations, unless very well crafted, actually are detrimental to the retention/retrieval of the main points of the document or the information to be learned.

• Strategy Choice

  My earlier work in this area examined group differences (young vs. old adults) in terms of tendency to adopt a particular strategy. The notion is that the cognitive resources that are required for more demanding memory retrievals are less available as one ages. The later papers explore this idea in more detail, examining individual differences in working memory resources. This work is the first attempt to fit individual performance at a fine grain, using only a single, pre-specified parameter to account for differences. In addition, the work describes our attempts to account for individual performance across tasks, using the same individual difference parameter. In other words, this work attempts to create zero parameter model fits of individual performance. Another project involves trying to predict individual differences in performing cognitive tasks by attempting to model individual subject performance in one task, using an estimate of that subject's working memory capacity, derived from a different experiment. That is, a single, individual difference parameter is estimated in one task and is used to fit an individual's performance across several tasks that vary in cognitive load. Almost all previous cognitive modeling efforts have been on aggregate data (averaged across subjects). Past efforts to model individual differences have aggregated subjects into two, or at most three, groups, e.g., low vs. high spatial, or low vs. high verbal. Schunn, C.D. & Reder, L.M. (2001).

• Factors affecting learning

  The general position espoused in these papers is that (a) practice in performing the tasks one wishes to learn is critical; learning by passively absorbing directions is not effective, but that (b) instruction that only focuses on practice in the anticipated situations without any generalized instruction or abstractions of principles is also likely to produce weak performance.

• Factors affecting comprehension and parsing

  Converging activation resulting from "top-down" processing affects comprehension. The paper by Anderson and Reder (1974) listed here shows that priming of an alternative meaning does not slow comprehension but may cause the wrong meaning to be selected altogether. The other papers demonstrate a failure to notice a mis-match in memory retrieval during parsing due to the heavy priming/activation of the schematic structure from the other elements in the question.

• Fan Effects: When do they help and when do they hurt memory retrieval and why?

  The result that there can be interference among competing associations to a concept has been known for many years, but its applicability in various contexts is not well understood.

We have begun exploring how the fan effect can explain the word frequency mirror effect (Reder et al., 2000, 2002; Cary & Reder, 2003) and contextual effects in memory such as matching font of the word from study to test (Reder, Donavos, & Erickson, 2002). The font fan effect also produces a mirror effect (Diana, Peterson, & Reder, 2004). We have also begun extending this effect of contextual fan to face recognition (Diana & Reder, 2002).

• Factors that affect strategy selection in question answering

  The work described below was among the first to present evidence that people (a) are variable in their strategy use, and (b) do not always attempt to search memory for a close match to the probe before electing to use some other type of question-answering strategy. Before this work was published, the accepted view was that memory would be searched for an answer before executing a "back-up" strategy such as computation or inference. Lemaire, P. & Reder, L.M.
