The false memory effect produced by the Deese/Roediger & McDermott (DRM) paradigm is reportedly impervious to warnings to avoid false alarming to the critical lures (D. A. Gallo, H. L. Roediger III, & K. B. McDermott, 2001). This finding has been used as strong evidence against models that attribute the false alarms to a decision…

The theme of this year's conference is "Sin Fronteras: Questioning Borders with(in) Mathematics Education." This theme is intended to encourage research presentations, discussion, and reflection on the variety of borders within mathematics education, as well as those that might be probed, challenged, explained, enhanced and/or…

Using 3 experiments, I examined false memory for encoding context by presenting Deese-Roediger-McDermott themes (Deese, 1959; Roediger & McDermott, 1995) in usual-looking fonts and by testing related, but unstudied, lure items in a font that was shown during encoding. In 2 of the experiments, testing lure items in the font used to study their…

In this experiment, syntactic constraints on the retrieval of orthography were investigated using homophones embedded in sentence contexts. Participants typed auditorily presented sentences that included a contextually appropriate homophone that either shared part of speech with its homophone competitor (i.e., was syntactically unambiguous) or had…

A set of design patterns for digital item types has been developed in response to challenges identified in various projects by teachers in higher education. The goal of the projects in question was to design and develop formative and summative tests, and to develop interactive learning material in the form of quizzes. The subject domains involved…

Subjects who named details in pictures performed better on subsequent recognition tests than their counterparts. Data support a model which assumes: (1) a constant probability of encoding a detail and (2) a detail is named either if it was encoded at study or with some bias probability. (Author/CP)

Two studies investigated the possibility that assessment of confidence is biased by attempts to justify chosen answers. These attempts include selectively focusing on evidence supporting the chosen answer and disregarding contradictory evidence. Results suggest that confidence depends on the amount and strength of evidence supporting the answer…

The influence of frequency of occurrence of a visual stimulus on encoding processes is investigated, to discover what mechanisms allow cognitive processes to modify perceptual processes. Six experiments are described and the results are discussed. (MH)

Four experiments investigated college students' judgments of inter-event contingency. Subjects were asked to judge the effect of a discrete response (tapping a wire) on the occurrence of a brief outcome (a radio's buzzing). Pairings of the possible event-state combinations were presented in a summary table, an unbroken time line, or a broken time…

A theoretical model is proposed for confidence in knowledge based on the assumption that people are good judges of the reliability of their knowledge, provided that the knowledge is representatively sampled from a specified reference class as defined by E. Brunswik (1943). Experiments with 177 college students support the theory. (SLD)

Five experiments involving a total of 268 college students indicate that people are especially likely to overinfer quantity or probability from numerosity when they are asked to make inherently difficult judgments, when they are asked to render judgments while performing a concurrent task, and when they are forced to make rapid judgments. (SLD)

Until recently, norms of experimental reasoning have lacked systematic theoretical development. Thus, it has been easy for psychologists like Tversky and Kahneman to misclassify certain human reasoning processes as being Pascalian and invalid, rather than as being Baconian and valid. (CP)

Past research indicates poor agreement about strategies people use to assess covariation between events. This research investigates method of assessment as one possible source of this low consensus. A set of problems was developed in such a way that different judgment rules would produce different decisions about the relationships between events.…

In multiple-choice items the response probability on an item may be viewed as the result of two distinct latent processes--a cognitive process to solve the problem, and another random process that leads to the choice of a certain alternative (the process of giving the actual response). An incomplete latent class model is formulated that describes…

The concept of probability is not an easy concept for high school and college students to understand. This paper identifies and analyzes the students' alternative frameworks from the viewpoint of constructivism. There are various interpretations of probability through mathematical history: classical, frequentist, and subjectivist interpretation.…
