Restricting one's access to temptations (precommitment) facilitates the achievement of long-term goals. The sophisticated impulsiveness model of precommitment posits that impulsive agents who are aware that they are impulsive should show the strongest preference for precommitment. Empirically however, two central predictions of this theoretical…

Many models of recognition are derived from models originally applied to perception tasks, which assume that decisions from trial to trial are independent. While the independence assumption is violated for many perception tasks, we present the results of several experiments intended to relate memory and perception by exploring sequential…

In answering general-information questions, a within-person confidence-accuracy (C-A) correlation is typically observed, suggesting that people can monitor the correctness of their knowledge. However, because the correct answer is generally the consensual answer--the one endorsed by most participants--confidence judgment may actually monitor the…

Examines five to seven year olds' assumptions about the experiential connotation of "I know that's X." Two experiments compare two groups of children (five and six year olds, six and seven year olds) who were asked to choose between items and asked whether they were sure or whether they knew they had made the right choice.

Discusses and applies to data models of juror decision making that make explicit what has been implicit in most previous theorizing about jury behavior--namely, a decision criterion and a distribution of apparent weight of evidence. (Author/RK)

Decision-theoretic testing is used to explore whether students can improve their realism, i.e. congruence between reported and true probabilities. Randomized sets of math problems were presented at computer terminals to 49 seventh graders from two classes (high/low achievers) over a period of three weeks. The subject assigned values to each of…

Describes a computer-based method of confidence-testing, available in batch processing and interactive form, which improves a student's ability to assess probabilities during clinical diagnosis. The methods and results of three experiments are presented. (EAO)

Effects of reviewing items and altering responses on examinee ability estimates, test precision, test information, decision confidence, and pass/fail status were studied for 376 examinees taking 2 certification tests. Test precision is only slightly affected by review, and average information loss can be recovered by addition of one item. (SLD)

This paper examines confidence testing, and reasons for using confidence tests. Different scoring systems are studied in order to clarify the meaning of significance of the weights which subjects assign to confidence scored tests. (DLG)

The level of confidence in pass/fail decisions obtained with computerized adaptive tests and paper-and-pencil tests was greater for 645 medical technology students when the computer adaptive test implemented a 90 percent confidence stopping rule than for paper-and-pencil tests of comparable length.

Studies in psychology and clinical decision making have shown that research subjects and physicians are often overconfident in the accuracy of their judgments. In these studies, groups of 20 first-year and 27 third-year osteopathic medical students at the Ohio University College of Osteopathic Medicine (Athens) were slightly underconfident in…

A study was conducted to improve confidence judgment (CJ) accuracy of college students through training in discriminating known from unknown information. Both low- and high-achieving college students were given CJ tasks, consisting of general information questions, before and after a brief training session. In addition, as part of the initial CJ…

This study investigates whether the practice of answer changing on multiple-choice questions (MCQs) is beneficial to Gulf Arab students' overall test performance. The proficiency exam used in this study is the Michigan English Language Institute College English Test - Grammar, Cloze, Vocabulary, Reading (MELICET-GCVR), which was developed using…

Individual and group assessments of quiz accuracy and students' discrimination of what they know and what they do not know regarding course material were examined using confidence ratings from 22 graduate students, 47 undergraduates, and their 23 heterogeneous learning groups over 6 quizzes. Students first took each multiple choice quiz as…

A student's choice of an answer to a test question is a coarse measure of his knowledge about the subject matter of the question. Much finer measurement might be achieved if the student were asked to estimate, for each possible answer, the probability that it is the correct one. Such a procedure could yield two classes of benefits: (a) students…
