In two experiments, recognition accuracy was compared between subjects who made frequency judgments and subjects who made recognition judgments. Results indicate that at least partially different information in memory is evaluated when judging frequency than when making recognition judgments and that this information facilitates recognition…

The paradigm producing recognition failure of recallable words was investigated in a series of three experiments. Results indicate that retrieval asymmetry: (a) exists in the recognition failure paradigm directly following list study, (b) increases significantly following a free-association task aimed at generation of the target words from the…

Research by Posner and Mitchell (1967) was used to investigate levels of noise processing in testing subjects' ability to "gate out" the processing of irrelevant and unwanted material. Three experiments are reported in which subjects had to judge whether two letters were the "same" or "different". Noise elements were included to test attention…

Three postulates are proposed concerning the manner in which persons infer the validity of propositions that do not necessarily follow logically from the information available. Implications of the proposed postulates for existing formulations of social inference and cognitive organization are discussed. (Editor/RK)

Discusses how the fast Fourier transform can be used as a teaching tool to introduce spectral analysis of sampled data by interactive minicomputer experiments. (MLH)

The experiment described was developed for the third-year course in inorganic and analytical pharmaceutical chemistry to provide students with "hands-on" experience with high pressure liquid chromatography. Assay procedures are given along with experimental parameters and student results. (LBH)

The salience of encoding attributes in instances of differing levels of category membership was examined using the release from proactive interference (PI) task with college students. Results are discussed in terms of providing converging evidence for Rosch's (1973,1975) theory of semantic category structure. (Editor/RK)

Gives a history of traditional and audiolingual methods of language teaching. Reports on one Swedish and two U.S. long-term experiments. The two methods are found to be of about equal value. The most recent publications reveal a tendency to synthesize the two. (Text is in German.) (IFS/WGA)

Describes an experiment on Doppler effects using air cars on a linear air track and a homodyne Doppler radar system. (SL)

Describes an experiment for second year students designed to illustrate lectures devoted to electrochemistry and thermodynamics. (SL)

Describes a method for demonstrating harmonic motion which utilizes a low frequency oscillator and three oscilloscopes. (SL)

Hypothesis refining is the combining of two separate rules (conjunctive concept), the combination of which is more accurate than either rule alone. Each of 70 subjects was reinforced independently for either rule alone or their combination under one and only one of seven reinforcement conditions. Tests Verplanck's paradigm, a model for studying…

The mini-course offers unusual opportunities for teachers and schools that wish to experiment with new forms. Certain very significant characteristics have to be present in order for the mini-course to be productive and eight important ingredients are listed here. (Author/RK)

Two experiments with college males examined the relationship between moral judgment and compliance in a modified Asch paradigm. Moral judgment was assessed using Kohlberg's dilemmas in one experiment and with Rest's Defining Issues in the second experiment. (Editor/RK)
