Representation and retention of three-event sequences in pigeons

The present experiments studied a three-event delayed sequence-discrimination (DSD) task: one arrangement (order) of two stimuli (red and yellow overhead lights) taken three in succession (e.g., red, yellow, red) was the positive sequence and the remaining seven arrangements were the negative sequences for responding and reward during the subsequent test stimulus. In Experiment 1, the final stimulus (recency) and the order of stimuli in the positive sequence controlled acquisition of discrimination. In Experiment 2, increasing the duration of memory intervals between stimuli reduced the discriminability of those negative sequences identical to the positive sequence after the delay. Three-event DSD performance in Experiments 1 and 2 was similar to two-event DSD performance in comparable published experiments. Models developed to explain pigeon performance in two-event DSD were extended to the three-event task. Results from both two- and three-event versions of the DSD task falsified a noncumulative model and several cumulative integration models (i.e., adding, averging, and some multiplying models), but corroborated one cumulative, multiplying model.     

The Twofold Assumption: A Response to Cole-Turner,Moritz, Peters and Peterson

Abstract

The article discusses points and perspectives offered by the four respondents to the R.J. Russell Fellow Lectures for 2013/14. Joshua M. Moritz and Ron Cole-Turner bring in new material from biblical and patristic traditions relevant for the proposal of deep incarnation. How does the concept of deep incarnation fare in relation to tradition and science? Ted Peters and Daniel J. Peterson raise questions about the compatibility between a compatibilist view of divine action and creaturely freedom on the one hand, and ideas of kenosis on the other. Which models of kenosis models are workable, and which forms of compatibilism?     

Some implications for psychological research of early versus late term participation by college subjects

Several surveys of recent psychological literature have indicated that a large percentage of human subjects are introductory psychology students who are given the option of selecting when to participate in research which is either implicitly or explicitly required of them. The present study was conducted to investigate the possibility that those subjects who choose to participate early in the term differ in personality and in attitudes toward research from later term participants. Results indicated that early term males and females, as expected, were more academically oriented and more internally controlled than late term subjects; and early term males were more achievement oriented than their late term counterparts. Additionally, females were found to feel more positive toward research participation than males; while a large percentage of all subjects reported both suspiciousness of experimenter intent and a general and unexpected willingness to voluntarily participate as subjects. Possible effects of these findings on research results and conclusions were discussed, and suggestions for improvements aimed at reducing self-selection bias in college subject pools were made.     

Psychiatry and Psychology in the Writings of L. Ron Hubbard

Objectives: Celebrity followers of the Church of Scientology have recently used their public forum to attack the modern practice of mental health. The practice of Scientology is rooted in the religious writings of its founder, L. Ron Hubbard. This paper will review the religious writings of L Ron Hubbard to understand Scientology’s position on mental health. Method: This paper reviews four of the major religious books written by L Ron Hubbard, in addition to a comprehensive overview of Scientology compiled by Scientology staff. Results: Hubbard’s theory of mind borrowed heavily from the earlier writings of Freud, until Hubbard’s psychological theory extended to include a spiritual existence that goes beyond the material world. The goal of Hubbard’s psychology and religion were to optimize the freedom of the individual, and he viewed psychiatry and psychology as inherently anti-spiritual and opposed to personal freedom and self-realization. Ultimately Hubbard presents a world view of potential nuclear world cataclysm, fueled by the geopolitical climate and mental health theories that dominated the mid 20th century. Conclusions: Hubbard’s writings mirrored the times in which he lived. His views that mental health practices are inherently anti-religious, freedom-inhibiting, and brain damaging do not reflect the modern-day practices of mental health. Dr. McCall is presently Professor and Chairman of the Department of Psychiatry and Behavioral Medicine at the Wake Forest University School of Medicine. He completed his medical degree and post-graduate psychiatric training at Duke University. He completed a Masters degree in Epidemiology from Wake Forest University. He is board certified in general psychiatry, geriatric psychiatry, and sleep disorders medicine. His research interests include depression, electroconvulsive therapy, quality of life, and insomnia. His research has been continuously funded by the National Institute of Mental Health since 1995, and he is author of more than 100 peer-reviewed journal articles.

NEW RELIGIOUS MOVEMENTS,TECHNOLOGY, AND SCIENCE: THE CONCEPTUALIZATION OF THE E‐METER IN SCIENTOLOGY TEACHINGS

This article is aimed at contributing to the study of the relationship that new religious movements entertain with technology and science. It focuses on an object that is central in Scientology's teachings and practice: the Electropsychometer or E‐meter. In interaction with the general public, such as in a 2014 TV Super Bowl advertisement, Scientology seems to claim a unique relationship with science and technology in the form of a “combination” and a “connection” evoked while displaying this very E‐meter. Hence, exploring the teachings related to it is relevant in order to understand how such combination or connection is conceptualized.
