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.     

Perception onset time during fixations in free viewing

In this study, we investigated when visual perception begins in fixations. During picture viewing, the picture was degraded at the beginning of selected saccades and changed back to the original after varying intervals. Participants manually responded whenever they detected changes. The change-backs were undetected when they occurred <6 msec after the end of the saccade, marked by the peak of the overshoot in dual Purkinje image eyetracker data, and detection reached asymptote 32 msec after that marker. Eye velocity at the change-backtime also affected detection likelihood. Apparently, perception begins around the time at which the eyes stop rotating at the end of a saccade, giving a psychological justification for measuring fixation durations from then. This also specifies the deadline for gaze-contingent display changes to occur without detectable image motion. Investigators using the dual PurMnje image eyetracker should consider the peak of the overshoot as the fixation onset time and measure intrafixational presentation times from then.     

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.
