Demonstrating the Effects of Presentation Rate on Aging Memory Using the California Verbal Learning Test (CVLT)

Previous research has repeatedly found that the elderly demonstrate significant declines in direct measures of memory. This study examined verbal learning and memory in the young and old participants using the California Verbal Learning Test (CVLT). We hypothesized that slowing down the presentation rate of a list of words, therefore giving the participants more time to rehearse while learning new information, would decrease the normal differences found between the young and old adults on memory recall. However, at a faster presentation rate, the usual differences would be found. Participants took the CVLT, and correct recall responses were measured as a function of age and presentation rate. It was found, as expected, that at the faster presentation rate, the young did significantly better than the old on recall, but at the slower presentation rate, the differences between age groups diminished. It was concluded that by giving the elderly more time to rehearse information, age-related differences in memory recall could be greatly diminished.     

Inhibitory processes and the control of memory retrieval

People are often confronted with reminders of things they would prefer not to think about. When this happens, they often attempt to put the unwanted memories out of awareness. Recent research shows that the capacity to suppress distracting traces is mediated by executive-control processes that are analogous to those involved in overriding prepotent motor responses, and it is these processes that cause persisting memory failures for the suppressed items. There is evidence that memory retrieval and motor tasks that are likely to demand executive control recruit overlapping neural mechanisms, suggesting that a common process mediates control in these domains. Together, these findings indicate that memory failures often arise from the mechanisms that lie at the heart of our capacity to influence the focus of thought.     

The topography of high-order human object areas

Cortical topography is one of the most fundamental organizing principles of cortical areas. One such topography - eccentricity mapping - is present even in high-order, ventral stream visual areas. Within these areas, different object categories have specific eccentricity biases. In particular, faces, letters and words appear to be associated with central visual-field bias, whereas buildings are associated with a peripheral one. We propose that resolution needs are an important factor in organizing object representations: objects whose recognition depends on analysis of fine detail will be associated with central-biased representations, whereas objects whose recognition entails large-scale integration will be more peripherally biased.     

Perception of correlated attributes involving African–American and white females' faces by 10‐month‐old infants

Thirty‐two 10‐month‐olds were habituated to stimuli containing an African–American female face or a white female face paired with a specific object. Test stimuli maintained or violated habituation stimuli pairings (i.e. categories). Results add to an emerging literature showing that 10‐month‐olds perceive categories of social information based on detection of correlated attributes. Copyright © 2003 John Wiley & Sons, Ltd.     

Tomboyism,Sexual Orientation,and Adult Gender Roles Among Israeli Women

The purpose of this study was to examine self-reported connections between sexual orientation (SO) and tomboyism in an Israeli sample. This study also focused on the connection between tomboyism and adult gender roles, and between gender roles and SO. A sample of 127 participants was solicited from lesbian organizations and from workplaces. Participants' SO was self-defined twice, using a forced choice and a Kinsey-type scale. Results revealed a connection between tomboyism and lesbianism. The overall level of tomboyism was lower then reported elsewhere. A relationship between tomboyism and gender roles emerged only for adolescence, and SO was only marginal related to gender roles. The definitions of tomboyism, cultural effects, Israeli society, adolescence gender roles, and bisexualism are discussed.     

A Foucauldian Foray into the New Genetics

A Foucauldian assessment of the common presumption that genetic information is potent and thus oppressive demonstrates that the concern may be misplaced. Foucault's concept of “technologies of self” reveals that genetic power originates not only from the potency of genetic information but from the penchant of individuals to victimize themselves in the name of optimal health, enhanced intelligence, perfect babies, or would-be immortality. Rather than seeking liberation from the power of the new genetics, Foucault's reinterpretation of the ancient understanding of concern for the self offers the possibility to avoid control by the scientific discourse. His ethical response calls for resistance rather than opposition and places responsibility for resistance in the hands of the subject. Characteristically, he avoids a generalizable form of morality but clarifies that resistance includes acknowledging the human appetite for perfection and subordinating science to ethical and aesthetic matters.
