Cornell College: Program in Science and Religion

Cornell College in Mount Vernon, Iowa, has established a new interdisciplinary program in science and religion. One of the features of this program is an undergraduate major in science and religion that requires substantial course work in at least one of the natural sciences as well as course work in philosophy, religion, and history. As a result of a grant from the John Templeton Foundation, Cornell College will offer a special course, God and Physics: From Aquinas to Quantum Mechanics (April 1998), and will sponsor an international symposium on creation and contemporary cosmology (April 1999). Opportunities exist for interested scholars to come to Cornell as Templeton Visiting Fellows in order to participate in these activities.     

When to Self-Correct?: A Comparison of Two Procedures on Spelling Performance

We compared the effects of two self-correction procedures on the spelling performance of 5 elementary school students with learning disabilities. Previous studies consistently have demonstrated self-correction to be more effective than traditional approaches to spelling instruction. However, we could find no single-subject design experiments analyzing the procedural details of how or when self-correction should be conducted to be most effective. For 4 days each week students practiced a list of 20 spelling words by listening to an audiotape on which the weekly list was dictated and writing the words. For half of each week's words, students checked and self-corrected after attempting each word; for the other half of the list, the students self-corrected after attempting all 10 words. An alternating treatments design showed self-correction after each word to be more effective for acquisition of new spelling words as measured by end-of-the-week tests for all 5 students, and maintenance of previously studied spelling words as measured by 1-week maintenance tests for 4 of the 5 students.     

Structural Stability within the Lateral Cerebellar Nucleus of the Rat Following Complex Motor Learning

Complex motor learning, but not mere motor activity, has been previously shown to induce structural modifications within the cerebellar cortex. The present experiment examined whether similar changes occur within one of the primary output targets of the region of the cerebellar cortex in which these structural changes were described, the lateral cerebellar nucleus (LCN; dentate nucleus). Adult female rats were randomly allocated to one of three training conditions. Acrobatic condition (AC) rats were trained to complete a complex motor learning task consisting of a series of elevated obstacles while motor control (MC) condition animals were forced to traverse a flat obstacle-free runway equal in length to the AC task. Inactive condition (IC) animals received no motor training. Unbiased stereological techniques and electron microscopy were used to obtain estimates of synapse number and postsynaptic density (PSD) length within the LCN. Results showed that neither synapse number nor PSD length was significantly altered as a function of training condition. These results indicate that complex motor skill learning is associated with structural plasticity within the cerebellar cortex and with structural stability within the lateral cerebellar nucleus.     

When worlds collide: Engineering students encounter social aspects of production

To design effective and socially sensitive systems, engineers must be able to integrate a technology-based approach to engineering problems with concerns for social impact and the context of use. The conventional approach to engineering education is largely technology-based, and even when additional courses with a social orientation are added, engineering graduates are often not well prepared to design user- and context-sensitive systems. Using data from interviews with three engineering students who had significant exposure to a socially-oriented perspective on production systems design, this paper argues that engineering students may have difficulty integrating in their own practice the technology-based and the socially-oriented perspectives on production. To enhance engineering students' ability to create systems that integrate both perspectives, and to relieve the intense cognitive and emotional pain that can be experienced by students exposed to both perspectives but unable to reconcile them, this paper reinforces the importance of teaching students the meta skill, design. A design perspective can help students integrate varied, sometimes conflicting, perspectives, and reach beyond customer-defined constraints to consider workplace and social impact.

Disinhibition of return: Unnecessary and unlikely

Recently, from data obtained with a temporal order judgment (TOJ) task, Gibson and Egeth (1994) concluded that inhibition of return (IOR; a response time effect that reveals slower responding to targets at previously cued versus uncued locations) reflects impaired perceptual processing. By replotting their data, we demonstrate that the perception of temporal order is influenced only by the facilitatory effect of a cue at short stimulus onset asynchronies (SOAs) and is unaffected by IOR at long SO As. The target paper proposed that, when extra stimuli are presented at task-relevant locations (i.e., in the TOJ task), IOR is prevented by a hypothetical process that is known as disinhibition of return (DOR). We argue that the assumptions that IOR affects perceptual processing and that DOR exists are unnecessary, as a more parsimonious response-based interpretation of IOR is consistent with their data. Further, we summarize recent results and present new data that demonstrate that DOR is unlikely.     

A Feminist Analysis of Seventeen Magazine: Content Analysis from 1945 to 1995

This study is an extension of the contentanalysis conducted by K. Peirce [(1990) AFeminist Theoretical Perspective on the Socialization ofTeenage Girls Through Seventeen Magazine, SexRoles, Vol. 23, pp. 491-500]. Her study examined thecontent of Seventeen magazine for the years 1961, 1972,and 1985, and the impact of the feminist movement fromthe 1960s through the 1980s. The present study explored the content of Seventeen magazine in the years1945, 1955, 1965, 1975, 1985, and 1995 to determine ifthe articles that are presented have changed in responseto the feminist movement from the 1940s to the present day. These results would supportthe contention that there is a relationship between thecontent of Seventeen magazine, in terms of traditionalvs. feminist messages, and the women's movement. However, these changes are slight and still donot reflect the various roles of teenage girls.Implications for further research arediscussed.
