Six Studies of Out-of-Body Experiences

Because of confusion between science and scientism, many people react negatively to the idea of scientific investigation of near-death experiences (NDEs), but genuine science can contribute a great deal to understanding NDEs and helping experiencers integrate their experiences with everyday life. After noting how scientific investigation of certain parapsychological phenomena has established a wider world view that must take NDEs seriously, I review six studies of a basic component of the NDE, the out-of-body experience (OBE). Three of these studies found distinctive physiological correlates of OBEs in the two talented persons investigated, and one found strong evidence for veridical, paranormal perception of the OBE location. The studies using hypnosis to try to produce OBEs demonstrated the complexity of a simple model that a person's mind is actually at an out-of-body location versus merely hallucinating being out, and require us to look at how even our perception of being in our bodies is actually a complex simulation, a biopsychological virtual reality.     

Response times and eye movements in feature and conjunction search as a function of target eccentricity

In four experiments, saccadic eye movements, reaction times (RTs), and accuracy were measured as observers searched for feature or conjunction targets presented at several eccentricities. A conjunction search deficit, evidenced by a large eccentricity effect on RTs, accuracy, and number of saccades, was seen in Experiments 1A and 1B. Experiment 2 indicated that, when saccades were precluded, there was an even larger eccentricity effect for conjunction search targets. In Experiment 3, practice in a conjunction search task allowed both RT and number of saccades to become independent of eccentricity. Additionally, there was evidence of feature-based selectivity in that observers were more likely to fixate distractors that had the same contrast as the target. Results are consistent with the view that the oculomotor and attentional systems are functionally linked and provide constraints for models of visual attention and search.     

Quantifying over the reals

Peter Geach proposed a substitutional construal of quantification over thirty years ago. It is not standardly substitutional since it is not tied to those substitution instances currently available to us; rather, it is pegged to possible substitution instances. We argue that (i) quantification over the real numbers can be construed substitutionally following Geach's idea; (ii) a price to be paid, if it is that, is intuitionism; (iii) quantification, thus conceived, does not in itself relieve us of ontological commitment to real numbers.     

Effects of self-monitoring and subsequent fading of external prompts on the on-task behavior and task productivity of elementary students with moderate mental retardation

This study investigated the effectiveness of self-monitoring on the on-task behavior and vocational production rates of 5 elementary students with moderate mental retardation during biweekly pre-vocational workshop sessions. They were taught to use a recording form to monitor their behavior and were cued to monitor by audiotaped tones. A multiple-baseline design across tasks was used to demonstrate a functional relationship between self-monitoring and both on-task behavior and task productivity. Once this relationship was demonstrated, the monitoring form and audiotape were withdrawn through fading procedures. Results indicated that (a) self-monitoring increased both on-task behavior and vocational task production rates, (b) performance gains maintained while cues and monitoring forms were withdrawn, and (c) gains maintained over several weeks in the absence of prompts (i.e., forms and tones).     

Analysis of systems influencing renal hemodynamics and sodium excretion. I. Biochemical systems theory

In this article we present a new methodology—Biochemical Systems Theory and Analysis—as an alternative to traditional parametric statistical procedures for investigating differences between risk groups in a population. We review the systems theory and how it can be used to represent a model of processes influencing renal hemodynamics and sodium (Na⁺) excretion. We also discuss the potential for new measures of the biology of common diseases that can emerge from a synergism between systems theory and population-based statistical approaches.

SELECTING A COST-EFFECTIVE SCREENING MEASURE FOR THE ASSESSMENT OF PRESCHOOL SOCIAL WITHDRAWAL

The utility of teacher judgment (rankings, ratings) and peer judgment (sociometric ratings) were studied as screening variables for preschool social withdrawal/responsiveness. Observational measures of preschoolers' interaction were used as the validation criterion based upon theoretical, empirical, and practical considerations related to development of a multipurpose behavioral assessment system. Results indicated that teacher rankings of students' verbal interaction frequencies (1) were most highly correlated to interaction rate in two preschool settings, (2) had test-retest reliability consistently above Rho = .80, and (3) were useful in that 77% of teachers using this procedure could identify their least socially responsive student within five rankings. The peer nomination sociometric rating was the least reliable measure at retest (Rho = .35) and showed consistently the lowest correlation with observational indices of interaction partner preferences, e.g., reciprocal rate (Rho = .29 to .39). The tendency for relationships among screening measures and the criterion to increase at retest suggested a training effect on screening accuracy. The use of teacher rankings in combination with observational measures to confirm selection accuracy and for monitoring treatment progress is discussed as a cost-effective behavioral assessment procedure for preschool social withdrawal/responsiveness.     

FROM YANG AND YIN TO AND OR BUT IN CROSS CULTURAL PERSPECTIVE*

Ancient Chinese metaphysics, as recorded some 4000 years ago in I Ching, the Book of Changes, expresses three fundamental characteristics of human thinking: (1) bipolar organization of the dimensions of cognitions; (2) attributions of positive polarity to the Yang pole and negative to the Yin; (3) parallelism in the orientation of the dimensions in terms of underlying Positiveness/Negativeness. In this paper, eight postulates governing the dynamics of interactions among cognitions are presented, utilizing both linguistic and psychological evidence. These postulates are used to predict the performance of native speakers of 12 languages – American English, Belgian Flemish, Swedish, Finnish, Hungarian, Serbo-Croatian, Turkish, Iranian Farsi, Hindi, Malaysian, Thai and Japanese - on a simple cognitive task: the insertion of their equivalents of and vs. but in the conjunction of pairs of familiar adjectives, X is ADJ₁ — ADJ₂ (e.g., X is tail BUT weak). The comparably measured affective meanings of the pairs of adjectives were found to predict the differential usage of and vs. but equivalents with high precision - in a frame which, linguistically speaking, will accept either conjunction - and these results displayed very high consistency across all 12 languages sampled. Yang and Yin appear to be universals of human cognizing and sentencing.     

Racial Differences in Children's Responses to Inequity1

Racial differences were examined in the responses of grammar school boys to an unfair distribution of rewards. Our primary interests were equity-restoration and inequity distress. Race of the three participants, allocator of rewards, beneficiary, and victim were varied in a factorial design. Generally, children who profited from the unfair distribution made no attempt to restore equity regardless of race. Black children who were victims did try to restore equity when the allocator was also black. All victims experienced emotional distress that was more extreme when the allocator's race was different from their own. Victims also justified their mistreatment by blaming themselves. There was no evidence of guilt on the part of the beneficiaries who disavowed the inequity. Thus equity-restoration through denial of responsibility by the advantaged and justification of inequity by the disadvantaged resulted in acceptance of a fundamentally unfair situation by beneficiary and victim alike.
