Family reunions: Visionary encounters with the departed in a modern-day psychomanteum

A poignant feature of many near-death experiences is a visionary encounter with deceased loved ones. Over the centuries, researchers have sought safe ways to replicate near-death and related experiences, hoping to induce the powerful aftereffects of these events. The ancient Greeks contructed psychomanteums, or oracles of the dead, where seekers could consult spirits of the deceased. I describe a modern attempt to recreate the psychomanteum. Like near-death experiences, visionary encounters in this modern psychomanteum are experienced as real and not as hallucinatory, and have profound personal aftereffects. This novel experimental technique may permit the scientific study of phenomena that previously occurred only spontaneously and under uncontrolled circumstances.     

Lever attacking by rats during free-operant avoidance

Rats pressed a lever to avoid shock on a free-operant avoidance schedule. Some subjects were also exposed to extinction in which the response-shock contingency was eliminated while the shock-shock contingency remained in effect. A specially constructed lever was used that registered not only presses, but also biting attacks on the lever. Throughout various phases of the study, shocks often elicited lever biting as well as post-shock responding. The results suggested that shock-elicited attacks that are forceful enough to activate the operandum might account for some of the responding that occurs in experiments on free-operant avoidance behavior. In particular, shock-elicited operandum attacking might account for post-shock response bursting during free-operant avoidance and the extreme persistence of responding sometimes noted when shocks are delivered during the extinction of avoidance behavior. To the extent that this is true, these phenomena should not be characterized as operant behavior in interpreting the results of experiments on free operant avoidance.     

A primate restraint and handling system for auditory research

A set of devices is described that enables daily handling and restraint of large primates. The animals live in cages and wear a special collar that fits into a modified primate restraining chair. A chain and pole arrangement simplifies the daily chairing procedure. A method of head restraint and earphone mounting is also described.     

Concurrent validity of the motor domain of the Vineland Adaptive Behavior Scales

The concurrent validity of the motor domain from the Vineland Adaptive Behavior Scales was estimated using scores from the Peabody Developmental Motor Scales as criteria. A moderately high correlation between the measures was obtained. Implications, particularly for preschool children, were discussed.

Reconsolidation Reconsidered

Some of the considerations that led to a consolidation interpretation of retrograde amnesia (RA), which states that RA results from the disruption of memory processing and storage when neural activity is interrupted by a brain insult, are reviewed here. The time-dependent gradient of memory loss (i.e., new memories are more vulnerable to amnesia than old memories) that characterizes RA seemed to fit nicely with the notion of a cascade of cellular events occurring during the immediate post-acquisition period that would transform a labile representation into a more stable form (i.e., consolidate the memory). However, a variety of observations came to challenge the storage-disruption model, and among these was the finding of amnesia for old but reactivated memories. A recent study by Nader, Schafe, and LeDoux (2000) provides an important analytic extension of the work on "reconsolidation" by showing that inhibition of protein synthesis in the lateral and basal nuclei of the amygdala immediately following the reactivation of old memory will induce retrograde amnesia. We offer a retrieval-oriented conceptualization to account for the temporal gradient and the "reconsolidation" phenomena.     

Effects of ontogeny on performance of rats in a novel object-recognition task

The current experiment investigated ontogenetic forgetting on a novel object-recognition task similar to that of Besheer and Bevins. 18-day-old pups (n = 49) and adult (n = 29) rats were tested at two retention intervals (1 min. or 120 min.). By employing exclusion criteria which demanded minimum amounts of object exploration at training and test, the performance of 18-day-old pups but not that of adults was significantly impaired at 120 min. relative to 1 min. Analysis indicated that the ontogeny of the learning and memory measured in novel object recognition follows a developmental trend similar to that of other forms of learning, with older animals remembering more and thus performing better than younger animals. Unfortunately, given the extreme variability inherent to the task and large N necessary to achieve significance, the use of this task in studies of learning, memory, and development is discouraged.     

Vicarious Experiences of Major Discrimination and the Life Satisfaction of Black and White Adults from a Community Sample

The racism-related stress framework argues that racism can influence the well-being of individuals through personal and vicarious experiences of discrimination, but studies on racism and health have primarily focused on understanding how personally experienced discrimination shapes these outcomes. Using data from the Nashville Stress and Health Study (N?=?1,252) the present study examines the racial differences in vicarious experiences of major discrimination among Black and non-Hispanic White adults from a community sample. Additionally, given longstanding evidence of racial disparities in life satisfaction, this study assesses whether the effects of vicarious experiences of discrimination influence overall life satisfaction of both Black and White adults. Results reveal significant racial differences in the types of vicarious discrimination that both groups are exposed to, and that Black adults are more exposed to vicarious experiences of major discrimination relative to White adults. Furthermore, findings indicate that vicarious experiences of discrimination, in addition to personal experiences of discrimination, are associated with lower levels of overall life satisfaction among Black adults, but not for White adults. This study extends the broader literature on racism-related stress and offers new insights for understanding racial differences in overall life satisfaction and well-being.
