Small systems of neurons are discussed as they relate to studies of simple animals and the generating of behavior from interacting systems. (SA)

The chemical dimension of the function of the brain is discussed in this article. The chemical transmitters or substances are related to the excitatory or inhibitory influence on neurons. (Author/SA)

Describes the Lock Box, a large rectangular container with ten latched doors each housing a different toy, which is designed to assess the spontaneous approaches of retarded children mental ages 2 1/2 to 5 1/2 to a problematic situation in which the subject is given abundant choice and scant structure. (CM)

A teacher describes the experiences of her fourth-grade students when using calculators during mathematics class. (MK)

Examined relationships among sex roles, sex, and learned helplessness. Students were given unsolvable concept-formation problems or solvable concept-formation problems. Feminine-sex-typed and masculine-sex-typed students showed cognitive and motivational deficits as well as dysphoric mood in helpless conditions. Helpless androgynous students…

Measured problem-solving abilities of narcotics abusers using the modified means-ends problem-solving procedure. Good subjects had more total relevent means (RMs) for solving problems, used more introspective and emotional RMs, and were better at RM recognition, but did not have more sufficient narratives than poor subjects. (Author/BEF)

Describes how an elementary teacher can incorporate science into the classroom even if he/she feels unsure in the realm of science. Emphasis is on using processes of science. (SA)

The possibility of improving problem-solving performance and increasing interest in mathematics by incorporating calculators in the mathematics curriculum was investigated. Results indicate that teachers can experiment with calculators in the classroom without fear of endangering computational skills and a thoughtful program integrating…

Describes a study which asked 1,000 American high school seniors to explain what they understood by the term "democracy." Findings showed large proportions of the students had some idea of what it meant, but they had difficulty in applying democratic principles to the solution of political conflict situations. (Author/CK)

Examines the premise that increased research provides important contributions to decision making. The study counterplan assumes that information can be developed in a way manageable to the policymaker, that study can assist in choosing from a variety of competing values, and that thoroughly researched decisions will be procedurally superior. (JMF)

Using as a case study an early nineteenth century philosopher and social anarchist named Josiah Warren, the article describes methods used to investigate a historical personage about whom little is written and much of what is written is contradictory. (Author/DB)

Although cognitive developmentalists explain moral stage progression in part by experiences of disequilibrium (cognitive disorganization, confusion, an anxious search for order), relevant data collected from 75 college students indicate that there is no difference in reported disequilibrium between those in moral transition and those not in moral…

A review of the representative research and theoretical literature on right hemisphere processes and psychophysiological models regarding the functional organization of the brain is presented. (Author)

Various classroom uses of simulation of random phenomena with a table of random digits are described. Examples are given to illustrate the mathematics of simulation. (MP)

Describes demonstrations of the risky shift phenomenon in eight social psychology classes of undergraduate and adult education students. Results showed that the phenomenon can be successfully and reliably demonstrated in a classroom. (CK)
