The main objective of this study was to compare the neurophenomenology of the Out-of-Body-Experience (OBE) state induced by hypnotic suggestion on a group of five selected participants with other states of consciousness, specifically the state of imagined OBE and hypnosis.

From a phenomenological point of view, a comparison of the OBE state with that of deep hypnosis, measured by using the Phenomenology of Consciousness Inventory, gave higher scores of Self-Awareness, Memory, Rationality, Voluntary Control and Imagery for the OBE.

From a neurophysiological perspective, the major difference – with respect to all other control conditions – was an increase in the power spectrum density and a decrease of coherence of the delta band when participants were required to answer questions posed by the hypnotist during their OBE state, suggesting that this could be the neurophysiological marker of this special state of consciousness.

We previously reported that contextual sensitivity correlates with the reproducibility of 100 psychology studies from the Reproducibility Project. This relationship remains after adjusting for several methodological factors believed to account for reproducibility. The current paper examines why the reproducibility rate of social psychology (28%) was lower than cognitive psychology (53%). The authors of the Reproducibility Project argued that the lower reproducibility rate of social psychology is due to weaker statistical power and effect sizes. The current paper finds no evidence for this hypothesis. Rather, new analyses suggest that different rates of reproducibility between social and cognitive psychology appear to stem from differences in contextual sensitivity rather than methodological factors (e.g., sample size, effect size). This will come as little surprise to social psychologists: The notion that human psychology is shaped by the social context has been the central premise of the field for nearly a century. We expect that same principle applies across the social sciences.

This paper developed an alternative statistical method for the analysis of time or space ordered data.The proposed method used the ranks of successive differences between the observations adjust for the order, direction and magnitudes of the successive differences. Chi-squared test statistic based on the ranks of the successively ordered data is developed to test for the possible existence of any statistical differences between the scores by subjects in the time or space ordered population. Some sample data were used to illustrate the proposed method. The result of the analysis shows that the present method is as powerful as some of the existing non-parametric methods that can be used for the same purpose at least for the present data but preferably for use if the available data set is ordered in time or space.
