Introduction: A correspondence has been seen between the level at which one can read scientific texts and his/her performance in writing this type of texts. Besides being able to read at the most complex levels, formulating research problems requires explicit training in writing. The objective of the present study was to evaluate whether…

Experiments to probe the nature of one mode of thinking, imagined spatial operations, have been devised. Results confirm that the mind can model physical processes, subjecting them to the geometric constraints that hold in the external world. The experimental work and implications are discussed in detail. (MNS)

Describes two new exercises in classical conditioning that use earthworms and houseflies. The animals are available year-round and pose no risk to the students or instructor. The conditioned stimuli are odorants. These elicit a conditioned response of contraction in worms or proboscis extension in flies. (MJP)

Provides a brief overview of single-subject research designs. This method exercises its power by examining changes in single subjects' responses over time across experimental conditions. Describes a classroom project in which students collect repeated measures of their own behavior and graph the data. (MJP)

Discusses the career and contributions of Russian educator and psychologist G. I. Chelpanov. Chelpanov founded Russia's first Psychology Institute and actively promoted psychological research and education. His resistance to Soviet efforts to introduce Marxist dogma into psychological research ended his career. (MJP)

Subjects for research in graduate psychology departments are frequently drawn from subject pools of undergraduates in introductory courses. Participation is often included among course requirements. A survey found some deviance from American Psychological Association (APA) ethical guidelines or federal law. Exemplary subject pool procedures and…

Maintains that time constraints and lack of supervisory support often result in truncated and derivative research projects in experimental psychology. Focusing on a research proposal can provide insight into the research process and require relevant data collection while avoiding the pitfalls of longer projects. (MJP)

Describes a study using self-report measures of students' responses to auditory and visual stimuli to measure distractibility in task performance among 224 Canadian undergraduates. Findings show the absence of any link between self-reported distractibility and actual performance. Study shows correlations between personality type and…
