Three experiments were conducted in which expectations of learning and transfer based on associative theory or frequency theory differed from those based on a theory of mental imagery. (Editor)

We test 3 theories of global and local scene information acquisition, defining global and local in terms of spatial frequencies. By independence theories, high- and low-spatial-frequency information are acquired over the same time course and combine additively. By global-precedence theories, global information acquisition precedes local…

Food words were considered as conditioned stimuli that elicit an appetitive emotional response. (Editor)

In two experiments adult subjects were given a redundant relevant cues concept identification problem. (Editor)

To show how a subject's memory of previous responses and their outcomes affects responding, as in Buchwald's cognitive model, the subject in the present study had to recall his previous response and its outcome before choosing the correct response. (Editor/RK)

This study is concerned with the transfer of learned helplessness from one aversive motivator, shock, to another, frustration. (Author)

Four free-recall experiments are reported that investigate the relationship between the organization of rehearsal and the organization of recall. (Editor)

This study highlights some theoretical ideas which should be considered in attempting to assess the degree of abstraction underlying conceptual learning. (Author/RK)

This article describes an experiment designed to define the difficulties perceived by learners in verbal learning tasks. (Text is in Spanish.) (CLK)

The purpose of this study was to extend the functional learning paradigm to the case where the relation to be learned is not stationary. (Author)

This study is designed to investigate the effects of cue discriminability on discriminative performance. (Author)

Three reaction time (RT) experiments using a modified Strenberg procedure were conducted to determine the number of memory representations maintained for perceptual (dot-pattern) concepts. (Editor)

A list discrimination paradigm was used to examine the effects of orienting tasks upon the later temporal discrimination of words. The orienting task involved judgments about the relatedness of the words in a list to some concept. (Editor)

If animals receive inescapable electric shocks, their subsequent avoidance-escape learning is poor. This phenomenon, which can be called "the interference effect", was studied in four experiments. (Editor)
