Two experiments are reported in which recall of the same information is compared following different priming passages. In one case the subjects were primed by material that was consistent with the content of the main passage; in a second case, the priming introduced information in conflict with it. It was found that inconsistent priming led to…

A laboratory experiment compared the relative effects of observing and participating in a first Prisoner's Dilemma Game (PDG) on subsequent PDG encounters by the original observer and participant. Concludes that vicarious experience is superior to direct experience in producing responses that reduce interpersonal conflict. Available from: Sage…

Describes a method for using ferrofluids to study steady-state resonant vibrations at liquid-air interfaces. (SL)

Reviews Galileo's experiments with falling bodies conducted at the Tower of Pisa. Results indicate it is doubtful that he could have obtained the results claimed in the legend. (SL)

Describes a quantitative experiment of measuring the characteristics of a cylindrical Langmuir probe and the ion density in the flame plasma of a seeded propane flame. (SL)

Two independent studies were conducted to examine the expectancy behavior of unselected hypnotic, task-motivated, and control-imagination subjects on a slide task requiring response to ambiguous visual information. Results showed that hypnotic subjects consistently demonstrated expectancy behavior, whereas nonhypnotic subjects did not. (Editor/RK)

Three experiments are reported that were designed to delineate the properties of the stimulus encoding stage in reaction time tasks of varying stimulus-response compatibility. (Editor)

Help children identify and use two basic elements in the scientific process. (Editor)

It was hypothesized that thought would result in greater attitude polarization than distraction and that this effect would be more pronounced with better developed "schemas" (naive theories) for thinking about the attitude object. (Editor)

Attempts to replicate Gogel's (1972) observations with points of light and examines in addition whether the same results would be obtained if the binocularly nearer object was made visually more massive than the farther object and if the residual oculomotor cues were varied to produce different values of the reference distance. (Author/RK)

Tests three proposed attentional mechanisms as possible behavioral strategies by which schizophrenics could prevent relevant information from registering and considers whether stimulation coming through the visual or the auditory channels is differentially susceptible to motivated attempts to disattend to relevant information. (Author/RK)

Seven-digit strings were presented for immediate recall. Before recall, subjects either read or retrieved from memory a single item (response prefix). Results were seen in terms of the sharing of the limited capacity of an active memory system by the memory series, the response prefix, and the operations to retrieve and emit the items. (Editor/RK)

Describes an experiment in which students use ion exchange chromatography to separate a mixture of chloro complexes of transition metal ions and then use spectrophotometry to define qualitatively the efficiency of the ion exchange columns. Background information, materials needed, and procedures used are included. (JN)

Provides directions for basic science experiments which demonstrate the rain cycle, fundamentals of cloud formation, and testing for the presence of acidity in local rainwater. Describes materials required, step-by-step instructions, and discussion topics. (NEC)
