Today, the use of formal preference assessments, including paired-stimulus preference assessments, is widely utilized to help determine which items to use as reinforcers during intervention. A second way to determine potential reinforcers is to analyze multiple dimensions of a stimulus in the moment, a procedure known as in-the-moment reinforcer…

Bayesian orthodoxy posits a tight relationship between conditional probability and updating. Namely, the probability of an event "A" after learning "B" should equal the conditional probability of "A" given "B" prior to learning "B". We examine whether ordinary judgment conforms to the orthodox view. In three experiments we found substantial…

Field work and field courses within undergraduate biology degrees have been under threat in recent years for multiple reasons and while there has been widespread support from learned societies, academic staff and students for the retention of field study, there has been little research to support the perceived value of field teaching within this…

A comparison was made between students' overall performance, as measured by overall grade, in different teaching and learning protocols: (1) traditional textbook and lecture along with standard examinations; (2) lectures with online augmentation and PowerPoint lecture notes along with standard examinations; (3) similar to "(2)" but with…

A conservation problem of numerical equivalence which 80% of adults reliably fail and 40% of third graders pass was developed, and responses of 188 subjects (Grades 2, 3, 5, 7, 9, 11 and college) to it and related number conservation and probability problems indicated that the differences in nonconservation were rooted in subjects' different…

This comparative case study investigated instructional methods that effectively enhance the development of students' critical thinking. Four institutions were selected for study; two at which students reported experiencing high degrees of growth in the ability to think critically, and two at which students reported experiencing low degrees of…

Compares the cognitive development of four subcultural groups of boys (Black and White, and lower- and middle-class) in order to test Arthur Jensen's theory. Nine-hundred subjects were studied for four years, and memory, intelligence, learning and transfer measures were employed. (Author/RH)
