On the electrophysiology of effective visual memory as measured by QEEG

An investigation into the QEEG parameters of effective cognitive functioning of visual memory for six Korean figures was conducted employing 69 normal subjects. Subjects studied the figures for 1 minute, engaged in an immediate 30-second quiet recall period, which was then followed by the subjects drawing the figures. A delayed recall of 45 minutes later followed the same methodology. The recall performances were correlated with the QEEG variables. For the input stage, total memory was determined predominantly by specific patterns of left frontal (F7, F3, Fpl) projections (phase and coherence activity) and left central/posterior (T3, C3, P3) phase (Alpha and Betal( 13–32 Hz)) projections. Success during immediate silent recall was determined by left frontal (F7, Fpl, F3) projections and left central/posterior (T3, T5, Ol, P3) projections in the Beta frequencies. Long term-delayed recall was determined by Ol coherence Alpha projection activity and Symmetry of Beta2 (32–64 Hz) at F8. Degree of activation variables (from visual attention and eyes closed) showed different patterns of successful activations.     

Faking and selection: considering the use of personality from select-in and select-out perspectives

The effects of faking on criterion-related validity and the quality of selection decisions are examined in the present study by combining the control of an experiment with the realism of an applicant setting. Participants completed an achievement motivation measure in either a control group or an incentive group and then completed a performance task. With respect to validity, greater prediction error was found in the incentive condition among those with scores at the high end of the predictor distribution. When selection ratios were small, those in the incentive condition were more likely to be selected and had lower mean performance than those in the control group. Implications for using personality assessments from select-in and select-out strategies are discussed.     

Intrinsic-Extrinsic Religiosity and University Students' Willingness to Donate Organs Posthumously

This research focuses on the links between intrinsic and extrinsic religious orientations as they relate to willingness to donate organs posthumously. Participants responded to a factual test of their knowledge about organ donation, indicated their degree of willingness to donate organs, and filled out personality inventories measuring their intrinsic and extrinsic orientations. The data indicated a high level of factual knowledge about organ donation. Also, contrary to Allport's (1966) arguments, people with an intrinsic religious orientation were not more likely to donate their organs, nor were people with an extrinsic religious orientation less likely to do so. Instead, it was found that intrinsic religiosity was unrelated to willingness to donate organs and that extrinsics with strong social orientations were more willing to donate their organs. Discussion centers on the need to develop more psy-chometrically sound measures of mature religiosity as a means of conducting a fairer test of Allport's original theorizing about intrinsic religiosity.     

Anticipating action in complex scenes

In four experiments we explored the accuracy of memory for human action using displays with continuous motion. In Experiment 1, a desktop virtual environment was used to visually simulate ego‐motion in depth, as would be experienced by a passenger in a car. Using a task very similar to that employed in typical studies of representational momentum we probed the accuracy of memory for an instantaneous point in space/time, finding a consistent bias for future locations. In Experiment 2, we used the same virtual environment to introduce a new “interruption” paradigm in which the sensitivity to displacements during a continuous event could be assessed. Thresholds for detecting displacements in ego‐position in the direction of motion were significantly higher than those opposite the direction of motion. In Experiments 3 and 4 we extended previous work that has shown anticipation effects for frozen action photographs or isolated human figures by presenting observers with short video sequences of complex crowd scenes. In both experiments, memory for the stopping position of the video was shifted forward, consistent with representational momentum. Interestingly, when the video sequences were played in reverse, the magnitude of this forward bias was larger. Taken together, the results of all four experiments suggest that even when presented with complex, continuous motion, the visual system may sometimes try to anticipate the outcome of our own and others' actions.     

Decisions About Testing and Termination of Pregnancy for Different Fetal Conditions: A Qualitative Study of European White and Pakistani Mothers of Affected Children

The aim of this study is to explore reasons for and against prenatal testing and termination for a range of conditions in women from two different ethnic backgrounds. A total of 19 Pakistani and European women in West Yorkshire, UK, who either had a child with a genetic condition or had terminated a pregnancy for one, completed a questionnaire about their attitudes regarding prenatal testing and termination for 30 different fetal conditions and were interviewed about their reasons for their responses. There were more similarities than differences between the Pakistani and European white women. The most important factor in most women’s decisions about termination of pregnancy was their perception of the quality of the life of a child with the genetic condition, in particular, whether the child would be “suffering.” This was described as either physical suffering, as a result of medical treatment, or as emotional suffering, as a result of psychological and/or social factors. These findings highlight the need for detailed information about the potential quality of life for the child and the child’s family to enable parents to make informed choices, particularly the extent to which the child is likely to suffer, the nature of such potential “suffering” and the extent to which the child could lead a “normal” life. The findings also challenge stereotypes about cultural differences in attitudes about termination of pregnancy.
