Suffixes have been shown to be recognized as units of processing in visual word recognition and their identification has been argued to be position-specific in skilled adult readers: in lexical decision tasks suffixes are automatically identified at word endings, but not at word beginnings. The present study set out to investigate whether position-specific coding can be detected with a letter search task and whether children already code suffixes as position-specific units. A preregistered experiment was conducted in Italian in which 3rd-graders, 5th-graders, and adults had to detect a target letter that was either contained in the suffix of a pseudoword (e.g., S in flagish vs. flagosh) or in a non-suffix control (e.g., S in flagish vs. flagosh). To investigate sensitivity to position, letters also had to be detected in suffixes and non-suffixes placed in reversed position, that is in the beginning of pseudowords (e.g., S in ishflag vs. oshflag). Results suggested position-specific processing differences between suffixes and non-suffixes that develop throughout reading development. However, some effects were weak and only partially compatible with the hypotheses. Therefore, a second experiment was conducted. The effects of position-specific suffix identification could not be replicated. A combined analysis additionally using a Bayesian approach indicated no processing differences between suffixes and non-suffixes in our task. We discuss potential interpretations and the possibility of letter search being unsuited to investigate small processing differences. We connect our example of failed self-replication to the current discussion about the replication crisis in psychology and the lesson psycholinguistics can learn.

Crisis In Psychology

This article outlines what we call the “narrative of psychology exceptionalism” in commentaries on the replication crisis: many thoughtful commentaries link the current crisis to the specificity of psychology’s history, methods, and subject matter, but explorations of the similarities between psychology and other fields are comparatively thin. Historical analyses of the replication crisis in psychology further contribute to this exceptionalism by creating a genealogy of events and personalities that shares little in common with other fields. We aim to rebalance this narrative by examining the emergence and evolution of replication discussions in psychology alongside their emergence and evolution in biomedicine. Through a mixed-methods analysis of commentaries on replication in psychology and the biomedical sciences, we find that these conversations have, from the early years of the crisis, shared a common core that centers on concerns about the effectiveness of traditional peer review, the need for greater transparency in methods and data, and the perverse incentive structure of academia. Drawing on Robert Merton’s framework for analyzing multiple discovery in science, we argue that the nearly simultaneous emergence of this narrative across fields suggests that there are shared historical, cultural, or institutional factors driving disillusionment with established scientific practices.

Crisis In Psychology

The recent ‘replication crisis’ in psychology has focused attention on ways of increasing methodological rigor within the behavioral sciences. Part of this work has involved promoting ‘Registered Reports’, wherein journals peer review papers prior to data collection and publication. Although this approach is usually seen as a relatively recent development, we note that a prototype of this publishing model was initiated in the mid-1970s by parapsychologist Martin Johnson in the European Journal of Parapsychology (EJP). A retrospective and observational comparison of Registered and non-Registered Reports published in the EJP during a seventeen-year period provides circumstantial evidence to suggest that the approach helped to reduce questionable research practices. This paper aims both to bring Johnson’s pioneering work to a wider audience, and to investigate the positive role that Registered Reports may play in helping to promote higher methodological and statistical standards.

Type Ii Errors

The present work aims to analyze the replicability crisis in psychology with a focus on statistical inference. The main objective is to highlight the risks to beware when performing hypotheses tests in a Frequentist framework. In addition to the classic Type I and Type II errors, two other errors that are not commonly considered are Type M error (magnitude) and Type S error (sign), concerning the size and direction of the effects. The first chapter introduces Null Hypothesis Significance Testing (NHST), the prevalent approach to statistical inference in the social sciences, following a historical perspective and presenting also the approaches of the statisticians Ronald Fisher, Jerzy Neyman and Egon Pearson. The second chapter discusses the replicability crisis in psychology with an analysis of the origins, the factors that contributed to the crisis and solutions proposed for a change of direction. The third chapter analyzes the role of Type M and Type S errors in the replicability crisis. Studies with a high probability of committing these two types of errors could provide estimates of effects that are exaggerated and/or in the wrong direction. Two types of analysis are presented to examine these errors before conducting a study (prospective design analysis) or once the study has already been conducted (retrospective design analysis). The fourth chapter aims to link Type M and Type S errors with the decline effect, which is the observation that the magnitude of effects decreases with repeated replications. Although there may be multiple reasons behind the decline effect, a possible explanation is that the original study overestimated the effect. A case study illustrates how a retrospective design analysis of the original study can provide information on the probability of Type M and Type S errors and give support to the hypothesis of overestimation. The final chapter summarizes the contributions of Type M and Type S errors to the replication crisis and the role of a design analysis in planning studies and analyzing results.

Hypnotic Suggestions

Hypnosis and hypnotic suggestions are gradually gaining popularity within the consciousness community as established tools for the experimental manipulation of illusions of involuntariness, hallucinations and delusions. However, hypnosis is still far from being a widespread instrument; a crucial hindrance to taking it up is the amount of time needed to invest in identifying people high and low in responsiveness to suggestion. In this study, we introduced an online assessment of hypnotic response and estimated the extent to which the scores and psychometric properties of an online screening differ from an offline one. We propose that the online screening of hypnotic response is viable as it reduces the level of responsiveness only by a slight extent. The application of online screening may prompt researchers to run large-scale studies with more heterogeneous samples, which would help researchers to overcome some of the issues underlying the current replication crisis in psychology.
