Whether humans can accurately make decisions in line with Bayes' rule has been one of the most important yet contentious topics in cognitive psychology. Though a number of paradigms have been used for studying Bayesian updating, rarely have subjects been allowed to use their own preexisting beliefs about the prior and the likelihood. A study is reported in which physicians judged the posttest p...

The present study aimed at investigating the effect of using language games on elementary students’ vocabulary retention. Thirty two numbers of students were chosen. They were at the same level of proficiency and were assigned into two groups of 16. The control group received traditional method of teaching vocabulary such as: drills, definitions, etc. and the experimental group was exposed to l...

We conducted six experiments to examine how manipulating perception versus action affects perception-action recalibration in real and imagined blindfolded walking tasks. Participants first performed a distance estimation task (pretest) and then walked through an immersive virtual environment on a treadmill for 10 min. Participants then repeated the distance estimation task (posttest), the resul...

The purpose of this study is to integrate the idea of concept map into dynamic assessment model for accounting education in vocational high school. By using the expert concept map and the objectives as the main reference to generate assessment questions for diagnosis purposes, students should be informed the shortcoming of learning and receive proper guidance to improve learning. A quasi-experi...

Practice of complex tasks can be scheduled in several ways: as whole-task practice or as practice of the individual skills composing the task in either a blocked or a random order. The authors used those 3 schedules to study 18 participants' learning of an orthopedic surgical task. They assessed learning by obtaining expert evaluation of performance and objective kinematic measures before, imme...

A Monte Carlo study was used to evaluate the effects of reductions in posttest variance on several methods for detecting predictors of change in a two-wave design. When the predictor was dichotomous, the analysis of covariance approach was compared to the analysis of variance on difference scores. For a continuous predictor, partial correlations, difference score correlations with the predictor...

Inference on treatment effects in a pretest-posttest study is a routine objective in medicine, public health, and other fields. A number of approaches have been advocated. We take a semiparametric perspective, making no assumptions about the distributions of baseline and posttest responses. By representing the situation in terms of counterfactual random variables, we exploit recent developments...

Poor awareness among medical graduates about basic life support (BLS) is a matter of great concern. The presence of a trained rescuer is the key determinant of ultimate survival from life-threatening emergencies. To achieve this goal, early exposure to such life-saving skills is the right decision to foster these skills for medical students, which can be reenforced in succeeding years. Forty-tw...

Introduction: Very little prospective, randomized, experimental research exists on the use of simulation as a teaching method, and no studies have compared the effects of 2 strategies of using the Human Patient Simulator (HPS) and a CD-ROM on the management of patients exposed to chemical agents. Methods: A prospective, pretest-posttest experimental, mixed design (within and between) was used t...

Collaboration is generally an effective means of learning new information, but is collaboration productive in domains where collaborators may hold qualitatively different conceptions of the domain’s causal structure? We explored this question in the domain of evolutionary biology, where previous research has shown that most individuals construe evolution as the uniform transformation of an enti...
