Adults and children judged mirror and nonmirror pairs of stimuli. The findings in this research suggested a nonperceptual explanation of mirror-image confusions, one involving conceptual and linguistic considerations. (Editor/RK)

Examines the position that the presence of contexts facilitates paired-associate learning through mediation. (Editor/RK)

Recognition memory has previously been shown to be better for unusual words than for common ones. Here it is seen that this word-frequency effect is reversed for extremely rare words. (Editor)

Considers two successive stages of processing dichotic lists of items. (Author/RK)

Three experiments were performed using a recognition probe procedure to test the subject's recognition of the order of two items from a dichotically presented list. (Editor)

Measures the phenomenal and the functional durations of visual stimuli differing in informational value. (Author/RK)

Four models of coalition formation are tested in a computer-controlled experiment in which three players negotiated to form coalitions in order to gain rewards for themselves. Various measures of the progress of negotiations are introduced, examined, and discussed. (Editor/RK)

A method of analyzing reaction time data in recognition memory is presented. A wide range of phenomena that any theory of recognition memory must explain is discussed. (Editor/RK)

Discusses research strategies employed in studies of the importance of adult social cues in controlling children's behavior, illustrating some of the limitations of sole reliance on laboratory paradigms for achieving an understanding of both the contemporaneous operation and the development of social cue effectiveness. (JH)

Discusses a project in which college students equipped a house with three different types of solar energy collectors and two vertical axis windmills. (MLH)

Tests the hypothesis that the effectiveness of discriminative stimuli as reinforcers is a function of the magnitude of the difference between them. (Author/RK)

Attempts to assess the effects of the mode and patterning of rehearsal on the acquisition and retention of modeled behaviors varying in organizational properties. (Author/RK)

Describes an experiment that illustrates the following points concerning the experimental determination of trypsin activity: (1) there is a difference in basing enzyme concentration on weight, absorbance, or active sites; and (2) the method of expressing enzyme concentration determines the value of specific, molecular, and catalytic center…

Describes an experiment in which the technique of ph-controlled extractive separation is used to separate a mixture of drugs aspirin (acidic), caffeine (basic), and phenacetin (neutral). (MLH)

Describes three experiments illustrating some technological applications of liquid crystal substances, which are currently used to display numbers and letters by scattering of ambient light. (MLH)
