The reminiscence circumplex and autobiographical memory functions

This study investigated the potential of a circumplex model to represent the functions of both reminiscence and autobiographical memory. Participants from four pre-existing data bases (i.e., Culley, LaVoie, & Gfeller, 2001; Webster, 1997, 2002; Webster & McCall, 1999) were combined, resulting in a total of 985 participants ranging in age from 17 to 96 (M age = 36.63 years). A total of 392 men (39.8%) and 591 women (60.1%), with two persons not reporting their gender, completed the Reminiscence Functions Scale (RFS) as part of the original four studies. The eight RFS factors were submitted to second-order factor analysis resulting in two orthogonal dimensions (self versus social and reactive/loss-oriented versus proactive/growth-oriented) accounting for 79.57% of the variance. Further, multidimensional scaling indicated that the original eight factors could be arranged in a circular fashion such that more closely related (i.e., more highly correlated) factors were placed closer together while factors less highly related were placed further apart. Advantages of a circumplex perspective for future theory and model development are illustrated.     

Color-luminance relationships and the McCollough effect

The McCollough effect is an orientation-specific color aftereffect induced by adapting to colored gratings. We examined how the McCollough effect depends on the relationships between color and luminance within the inducing and test gratings and compared the aftereffects to the color changes predicted from selective adaptation to different color-luminance combinations. Our results suggest that the important contingency underlying the McCollough effect is between orientation and color-luminance direction and are consistent with sensitivity changes within mechanisms tuned to specific color-luminance directions. Aftereffects are similar in magnitude for adapting color pairs that differ only in S cone excitation or L and M cone excitation, and they have a similar dependence on spatial frequency. In particular, orientation-specific aftereffects are induced for S cone colors even when the grating frequencies are above the S cone resolution limit. Thus, the McCollough effect persists even when different cone classes encode the orientation and color of the gratings.

Neonatal treatment with monosodium glutamate does not alter grooming behavior induced by novelty or adrenocorticotropic hormone

The increased grooming behavior observed in a novel environment has been attributed to release of peptides derived from proopiomelanocortin (POMC), such as ACTH, alpha-melanocyte-stimulating hormone (alpha-MSH), or beta-endorphin, which themselves can elicit grooming. This is because novelty-induced grooming is attenuated both by hypophysectomy and by antiserum to ACTH injected into the cerebral ventricles. Administration of monosodium glutamate (MSG) to neonatal rats destroys neurons in the arcuate nucleus of the hypothalamus, depleting the brain of POMC peptides, and also hypothalamic dopamine and choline acetyl-transferase activity. Neonatal MSG treatment did not significantly alter the grooming scores of adult rats in either home or novel environments compared to saline-treated animals. There were also no differences between MSG-and saline-treated rats in the grooming scores observed following graded doses of ACTH1-24 (0.2-1.0 micrograms) administered intracerebroventricularly. Thus if increased grooming in the novel environment is due to release into the ventricles of ACTH, alpha-MSH, beta-endorphin, these peptides more likely derive from the pituitary rather than from brain cells, although the failure of the MSG treatment to produce quantitative depletions of cerebral POMC peptides, especially in the brain stem, leaves open the latter possibility.     

The effects of a videotape feedback system on classroom teacher behavior

Teachers in eight matched schools, four experimental and four control, were videotaped to examine the effects of a staff development program utilizing knowledge of objectives and immediate videotape feedback to modify the behavior of classroom teachers. Playback teachers improved cognitive behaviors but not affective behaviors more than controls. Concomitants of teacher success in the program were also investigated. Characteristics contributing to positive behavioral changes were dissatisfaction with perceived effectiveness, teaching experience, recency of latest degree, teacher attitude toward students, and student achievement.     

Spatial-frequency-contingent color aftereffects: Adaptation with two-dimensional stimulus patterns

The spatial-frequency theory of vision has been supported by adaptation studies using checkerboards in which contingent color aftereffects (CAEs) were produced at fundamental frequencies oriented at 45\dg to the edges. A replication of this study failed to produce CAEs at the orientation of either the edges or the fundamentals. Using a computer-generated display, no CAEs were produced by adaptation of a square or an oblique checkerboard. But when one type of checkerboard (4 cpd) was adapted alone, CAEs were produced on the adapted checkerboard and on sine-wave gratings aligned with the fundamental and third harmonics of the checkerboard spectrum. Adaptation of a coarser checkerboard (0.80 cpd) produced CAEs aligned with both the edges and the harmonic frequencies. With checkerboards of both frequencies, CAEs were also found on the other type of checkerboard that had not been adapted. This observation raises problems for any edge-detector theory of vision, because there was no adaptation to edges. It was concluded that spatial-frequency mechanisms are operating at both low- and high-spatial frequencies and that an edge mechanism is operative at lower frequencies. The implications of these results are assessed for other theories of spatial vision.     

Characteristics of the System of Production of History-of-Psychology Literature, 1975–1986

We used Psychological Abstracts to identify a large international sample of history-of-psychology literature that was published from 1975 through 1986. Information was obtained on such producer characteristics as: The language in which each publication was written; the country (or American state) from which it originated; and authorship gender and number. Differences in productivity were examined as a function of these variables and their combinations; comparisons were made with a random sample of psychological literature and with previously published findings regarding publication in psychology. Conclusions were drawn regarding the history of psychology considered as a literature-producing enterprise.
