The impact of HIV infection on society's perception of clinical trials

All international codes of research ethics and virtually all national legislation and regulation in the field of research involving human subjects project an attitude of protectionism. Written with the aim of avoiding a repetition of atrocities like those committed by the Nazi physician-researchers, calamities like the thalidomide experience, or ethical violations like those of the Tuskegee syphilis study, their dominant concerns are the protection of individuals from injury and from exploitation. In recent years, however, society's perception of clinical research has shifted dramatically. Now, largely as a consequence of the efforts of the AIDS activists, clinical research is widely perceived as benign and beneficial. Although this shift in attitude has resulted in some important improvements in research policies and practices, this new perception is just as wrong-headed as was the earlier excessive protectionism. It is necessary to maintain a balanced perspective; our policies should encourage the conduct of ethical research while maintaining the vigilance necessary to safeguard the rights and welfare of the subjects.     

Modifying law enforcement training simulators for use in basic research

Several approaches to using simulation as a method for teaching good judgment in the use of firearms by law enforcement officers and military personnel were investigated for their potential applications to research: the GAMMA Live Fire Video Training System, the FireArms Training Systems Simulator (FATS), and the Judgment Under Stress Training (JUST) simulator. Each instrument uses real-time, computer-controlled, life-sized projected video images of scenarios that may or may not present a threat, and handguns that fire real or simulated ammunition. The subjects respond to a sequence of “shoot/no-shoot” judgment scenarios resulting in data on judgment, reaction time, and accuracy. The JUST simulator was found to be more easily modifiable in capturing data on performance at microanalytic levels. Although true interactive simulations are not feasible with this system, this was not seen as a hindrance to its usefulness for research.

Development of calculation abilities in young children.

This study investigates the development of skills for solving verbally and nonverbally presented calculation problems in children between 4 and 6 years of age. Identical addition and subtraction calculations were presented in three problem-type formats: nonverbal problems, story problems, and number-fact problems. The nonverbal problems involved presenting sets of physical referents that were then transformed either by adding or removing elements. The child saw the initial set and the number of elements that were added or removed, but not the final set. The task was to construct an array that contained the number of elements in the final set. The story problems and number-fact problems were presented orally, without props. Results indicate that children as young as 4 years of age have some success on the nonverbal problems, showing that they can transform sets by adding or subtracting elements. In contrast, children do not achieve comparable levels of success on the story problems or number-fact problems until 5 1/2 to 6 1/2 years of age. Moreover, throughout the age range tested, children performed better on nonverbal problems than on either story problems or number-fact problems. These results suggest that children's earliest ability to add and subtract is based on experiences combining and separating sets of objects in the world and that this ability precedes the development of conventional verbal methods of calculating.     

Spatial problem solving: The integration of independently learned cognitive maps

The process of mentally integrating separate regions of a layout into a unified representation is a critical component in generating inferred spatial information. Blindfolded subjects learned two different paths by tactual exploration. The subjects were then given information that permitted them to integrate the two cognitive maps of the paths into one map. In Experiment I, the speed and accuracy of originally learned and inferred movements within a path were equivalent, whereas inferred movements between the two paths were significantly slower and less accurate. In Experiment 2, the subjects could request additional training on the paths before they were given the integration information, and they also rated how well they knew the path on which they were tested. When the subjects judged that they remembered all or most of the path information, movements between two paths and within one path were performed with the same accuracy. The equivalent accuracy of all the movements suggests that cognitive integration can generate an accurate representation of an integrated layout when the path information is recalled.     

Autobiographical remembering and hypermnesia: a comparison of older and younger adults

This study examined age differences in autobiographical memory and extended findings concerning hypermnesia in laboratory tasks to a real world event, the announcement of the verdict in the O. J. Simpson murder trial. Older and younger adults repeatedly recalled the event in a single session. Interviews were coded for amount and type of accurate information and for errors. The age groups did not differ in ability to recall the gist of the event or in the number of errors made. Younger adults were better at remembering when the event had occurred. Both age groups showed hypermnesia. The results are discussed in terms of the importance of autobiographical memory across the life span and the phenomenon of hypermnesia in everyday memory.     

Remembering children's emotions: sources of concordant and discordant accounts between parents and children.

Parents were asked to recall recent events that had evoked happiness, sadness, anger, and fear in their children. Children (N = 77, 2.3-6.6 years) indicated whether they remembered each event, and if so, they described the event and how it had made them feel. Agreement between parent and child concerning how the child felt varied as a function of emotion. Children agreed with their parents' emotion attributions most often for events that parents recalled as having evoked happiness and sadness, less often for fear, and least often for anger. Children disagreed with parents' attributions of happiness and sadness most often when parents and children differed concerning the attribution of children's goals. Discordant reports about children's anger were most frequent when parents and children reported conflicting goals. Discordant reports about fear were most frequent when parents and children focused on different parts of the temporal sequence surrounding the event.     

Fear of failure in males: A more salient factor than fear of success in females?

Sex differences in self-attributions following winning or losing in a highly competitive achievement-type situation were investigated. Subjects competed in same- or mixed-sex pairs on an anagram task which was prearranged in difficulty so that one subject would clearly defeat his/her partner. A significant sex of subject × outcome interaction emerged. Males were more likely to attribute their successes to skill and failures to luck. Females attributed both their successes and failures to a relatively equal amount of skill. This self-defensive bias in males was interpreted as indicating a greater fear of failure in males. The relatively rational and objective attributions of females did not support a female fear of success hypothesis. No significant interactions with sex of partner on this variable were found. Finally, subjects were asked to rate their opponents on a series of personality, attractiveness, and happiness dimensions. Neither males nor females were differentially evaluated as a function of winning or losing.The research reported here was partially supported by a grant to the first author from the California State University, Fresno Foundation.
