Information theory was used to qualify the difficulty of verbal discrimination (VD) learning tasks and to measure VD performance. Words for VD items were selected with high background frequency and equal a priori probabilities of being selected as a first response. Three VD lists containing only 2-, 3-, or 4-word items were created and equated for…

Experiment was designed to isolate the incentive properties of uncertainty reduction (information) from those of material reward value and vaiety in a binary, competitive reward situation. (Author)

Results indicated that subjects in each source of blame group responded with significantly less amplitude and speed following interruption than noninterruption. (Authors)

The finding that the impulsivity-reflectivity dimension was not related to risk-taking behavior was clearly unexpected. (Author)

This study indicates that a period of positive prior contact between a child subject and an adult experimenter may result in a relative decrease in performance for material reward dispensed by that adult experimenter. (Authors)

Subjects learning high-frequency names had significantly better recall, confirming that color memory is a function of linguistic codability, not perceptual experience. (Author)

Study investigated the nature of the information that is available to Ss when they have comprehended linguistic materials. (Authors)

Results of experiment clearly indicate the superiority of forward associations. (Author)

In the present study the relationships between the amount of freedom given the learner in choosing a learning task and his subsequent performance and persistence on that task were investigated. (Author)

Reflective subjects generated characteristically different and more efficient hypothesis-testing strategies than impulsive subjects. (Author)

These results stand in sharp contrast to those previously reported which concluded that most college students will abandon conservation; the present finding is of strong (though less than perfect) resistance. (Authors/CB)

Study considered whether distinctive orthography would lead to differential recognition performance when high- and low-distinctiveness words served as both study and distracter items. (Author)
