Perceptual learning in maze discriminations

In Experiment 1, rats were trained on a discrimination between rubber- and sandpaper-covered arms of a maze after one group had been pre-exposed to these intra-maze cues. Pre-exposure facilitated subsequent discrimination learning, unless the discrimination was made easier by adding further discriminative stimuli, when it now significantly retarded learning. In Experiment 2, rats were trained on an extra-maze spatial discrimination, again after one group, but not another, had been pre-exposed to the extra-maze landmarks. Here too, pre-exposure facilitated subsequent discrimination learning, unless the discrimination was made substantially easier by arranging that the two arms between which rats had to choose were always separated by 135°. The results of both experiments can be explained by supposing that perceptual learning depends on the presence of features common to S+ and S-.     

International Applications of Computer-based Testing and Interpretation

The computer has been used to administer, score and interpret psychological tests in a number of countries throughout the world. This paper traces early work in the United States, Great Britain and continental Europe and reviews the current international status of computer-assisted psychological testing. Several problems with transporting existing computer-based psychological testing technology across languages and cultures are discussed.
Les ordinateurs sont utilisés pour administrer, noter et interpréter les tests psychologiques dans un certain nombre de pays du monde entier. Cet article évoque les travaux réalisés aux Etats-Unis, en Grande Bretagne et en Europe Occidentale, et passe en revue les données du courant international en la matière. Plusieurs problèmes technologiques sont soulevés par la diffusion de ces tests, notamment sur les plans du langage et de la culture.     

How a maximizing orientation affects trade-offs between desirability and feasibility: The role of outcome- versus process-focused decision making

This research examines how maximizers make decisions when they must trade-off between desirability and feasibility attributes. Across four studies, we demonstrate that maximizers tend to prefer choices offering more desirability to those offering more feasibility and respond more favorably to a product's advertising when it highlights desirability more than feasibility attributes. Furthermore, we show that maximizers' focus on outcomes rather than processes drives their preference for desirability, such that changing from an outcome to a process focus can redirect their interest from desirability to feasibility. By contrast, satisficers do not prefer products higher in desirability to those higher in feasibility and are not more receptive to ads highlighting desirability attributes. Furthermore, because satisficers may focus on both the outcome and the process, priming either one is redundant and does not alter their preference for desirability or feasibility.
