Reviews sixty-eight experiments published in various journals in 1973 and 1974 and concludes that communication experimentation may be severely limited by the nature of the subjects studied and the inappropriate handling of experimental reactivity. (MH)

Derives the magnetic field as a function of position between two capacitor plates during discharge with the use of the integral form of Ampere's law and real currents only. The displacement current must be included to obtain the same result for arbitrary choices of contours. (Author/GA)

This study evaluated the applicability of the averaging model of the information integration theory to attitude formation in a classroom situation and compared the results of an in-classroom and an in-laboratory application of equivalent stimuli (verbal vs printed). Results confirmed both the information integration theory and the averaging model.…

Three classic visual toys are discussed and instructions are given for their construction. These are moire patterns, kaleidoscope, and stereoscope. (MP)

Reports a series of experiments that give evidence for retention of information about color in very short-term visual memory, commonly termed "iconic memory". (Author)

Male students worked under a supervisor who was male or female, autocratic or democratic, and possessed a sex-role congruent or incongruent job title. For female supervision only, the more traditionally incongruent the situation, the more unfavorable were the verbal reactions elicited. Task performance and written evaluation of the supervisor were…

Investigates the effect of specificity on retention following nonsemantic processing. Five experiments are reported in which structural specificity was manipulated along with either phonemic or orthographic dimensions, and process specificity was manipulated by variations in the nonsemantic orienting tasks. Data are interpreted in terms of a…

With the use of graphs, the phenomenon of deep ocean water mixing is discussed. Research methodologies and findings are detailed. (CP)

Analyzes the distributions of particles and particle flux in the Atlantic Ocean. (CP)

Explains the importance of sulphur dioxide and tannin to wines. Describes analytical procedure to determine their amounts in Australian wines. (GA)

Examines the effects of consensus information on the prediction of behavior as a function of social desirability of consensus information and the presence or absence of vignette information about target persons. Discusses the different manners in which consensus information can be used. (Author/RK)

Cognitive psychology lacks explicit theories that encompass more than a single experimental paradigm. This research presents a theory of memory retrieval that not only applies over a range of paradigms but also deals with experimental data in greater depth and more detail than competing models. The theory provides a rationale for relating…

While there has been considerable success in isolating the dimensions of acoustic information that are important in perceiving and identifying speech sounds, very little is known about how the information from the various acoustic dimensions is put together in order to actually accomplish identification. Proposes and tests a model of these…

Compares the rates of forgetting of five-item sequences of acoustically similar and dissimilar consonants and words in the absence of proactive and retroactive interference in order to test whether within sequence similarity rather than stimulus length would have a greater influence on retention. (Author/RK)

Previous research has suggested that children are aware of changes in "orientation" prior to changes in "position" of objects as a function of an observer's viewpoint. Two question-asking studies investigated this finding relative to (a) changes in type of stimuli and (b) changes in response mode. (Editor/RK)
