Title:
The role of experimenter and participant mindset in the replication of psi experiments: Phase II of a global initiative
Publication year: 2017
Abstract/Results:
ABSTRACT:
The proposed study seeks to expand a global initiative to examine the replication problem in psi research through the manipulation of experimenter and subject mindset for the presence or absence of a psi effect. The meta-study builds upon an international collaboration of teachers, student experimenters, and experimental volunteers, who will make use of a standardized psi protocol developed by Daryl Bem that has been the focus of recent replication attempts and that allows for a systematic collection of data under well-controlled conditions. In particular, Bem’s studies were designed to be simple and transparent, requiring no instrumentation beyond a desktop computer, taking less than thirty minutes per session, and requiring simple statistical analyses.
Our previous BIAL project attempted to replicate Bem’s results and to factor in prior beliefs about psi held by experimenters and participants, in which we have found significant effect. In the current proposal we assess further the influence of experimenters’ and participants’ mindset by manipulating their expectancy through either a pro-psi or anti-psi video induction before the experiment. A cross-over design was used to balance experimenter and participant mindset manipulation. Experimenters was kept blind as to the condition of the Participants.
Experimenters received a prerecorded, web-based experimenter orientation training, a 5 item belief scale that was used in our first study, and a mindset manipulation (pro or anti-psi), the focus of the proposed work. Experimental participants were recruited and tested on the retrocausal priming experiment by the experimenter.
After the introduction and psi mindset manipulation phase, each experimental session consisted of 40 trials. In each trial an image will be randomly selected and displayed, followed by a randomly selected incongruent (one is pleasant, the other unpleasant) or congruent (both target picture and prime are pleasant or both are unpleasant) priming word. Experimental participants were instructed to identify images as “pleasant” or “unpleasant” as quickly as they can; after participants respond the priming word flashes briefly (at which point they do nothing until the next image shows). A total of 20 “unpleasant” and 20 “pleasant” images followed by a priming word (20 congruent and 20 incongruent) will be shown. The results of the psi task – an analysis of the “congruent” vs. “incongruent” selection response times– will be the dependent measure for both the psi replication attempts and for the experimenter and participant mindset manipulations.
We pre-registered the study with the Koestler Parapsychology Unit. One out of 32 experimenters had significant results in the direction of the hypothesis, although this may be expected by chance. We failed to observe an effect in our primary hypothesis about the presence of psi in this task, although significance reached between p=0.11 and p=0.15 (depending on the test being used) two tailed (0.055 to 0.075 one tailed). We failed to observe an effect of the priming procedure. While not confirming the presence of psi in this task, this data (comprising more than 600 usable individual sessions) will help increase statistical power when combined with data previously collected under our previous BIAL project and the data currently being acquired.

Experimenter effect and replication in psi research
Publication year: 2016
Abstract/Results:
ABSTRACT:
This study addressed the replication problem in parapsychology through the examination of experimenter and participant belief in psi and their impact on the outcome of a psi task. The meta-study involved an international collaboration of teachers, student experimenters, and experimental volunteers, who made use of a standardized psi protocol that has been the focus of a number of replication attempts and that allows for a systematic collection of data under well-controlled conditions (Bem, 2011). It included 12 different laboratories across 32 experimenters and 512 participants. While the preregistered hypothesis that was assessed on a participant basis did not show a significant psi effect, when the statistical power was increased by using a single
trial analysis, the primary hypothesis was highly significant. The results did not support a correlation between study outcome and experimenter expectancy. Overall, these results support the feasibility of a multi-laboratory collaboration and show that single trial analysis might be more appropriate and powerful to process these types of data.

Abstract/Results:
ABSTRACT:
BACKGROUND
This study addressed the replication problem in parapsychology through the examination of experimenter and participant belief in psi and their impact on the outcome of a psi task.
AIMS
This experiment involves a modified version of the previous attempt where we are influencing expectancies of experimenters and subjects. In this experiment, after showing either randomized pro or anti-psi statements (for participants) and videos (for experimenters), we are assessing the experimenters’ and/or participants’ expectation using questionnaires.
METHOD
This study made use of a standardized psi protocol developed by Daryl Bem that has been the focus of several recent replication attempts and that allows for a systematic collection of data under well-controlled conditions. The study required no instrumentation beyond a desktop computer, thirty minutes per session, and requiring statistical analyses no more complex than a t-test across sessions or participants. Specifically, the replication protocol tested the retroactive priming aspect of experiment 4 of Bem, 2011) by examining reaction time for congruent or incongruent pairing of words and pictures.
RESULTS AND CONCLUSIONS
The results of the psi task are the dependent measure for both the psi replication attempts and for the experimenters’ and subjects’ expectancy effects. The pre-registered hypothesis did show a trend in the expected direction for the psi replication (p=0.055, one tailed) but not for the experimenter effect. These results will be published at the PA conference 2018, and will be compiled with results from experiment 233/12 and 189/16 in a peer reviewed and indexed journal article.

Abstract/Results:
ABSTRACT
This replication issue in parapsychology was studied through the examination of experimenter and participant belief in psi and their impact on the outcome of a psi task. This series of three formal experiments employed a standardized psi protocol developed by Daryl Bem that has been the focus of several recent replication attempts and that allows for a systematic collection of data under wellcontrolled conditions. A session lasted no more than 30 minutes per subject. Specifically, the replication protocol tested the retroactive priming aspect of experiment 4 of Bem (2011) by examining reaction time for congruent or incongruent pairing of words and pictures. Study 1 examined expectancies of 32 experimenters and 512 subjects. Study 2 manipulated priming for expectancies by showing either randomized pro or anti-psi statements (for participants) and videos (for 32 experimenters), to assess the experimenters’ and/or expectation using questionnaires in 640 participants. In this article, we are reporting the results of Study 2. The results of the psi task are the dependent measure for both the psi replication attempts and for the experimenters’ and subjects’ expectancy effects. All analyses were run according to the document pre-registered prior to the start of the experiment. Although a trend in the expected direction was observed when comparing congruent image-word pairs versus incongruent ones for all subject combined, it fails to reach the 0.05 (two-tailed) significant threshold. No effect of subjects’ expectancy was observed. Study 3, which is now in process, uses implicit measures to examine expectancies of 32 experimenters and 512 participants.
