Selection Bias in Psychedelic Research: Comparing Self-Reported Quality-Of-Life Impact Between Enthusiasts and a General Population Sample
Psychedelic experiences have been associated with improved quality of life, but many studies rely on samples of enthusiasts, raising concerns about selection bias. This study examined whether self-reported quality-of-life impact differed between a convenience sample of psychedelic enthusiasts and a general population sample recruited through Prolific, and whether sample differences persisted after controlling for mindset, setting, motivation, and…
How bad is bad? Perceptual differences in the communication of severity in intimate partner violence
Accurate communication of the severity of violence in intimate relations is essential for the appropriate evaluation of offenders and victims in contexts such as court trials, custody cases, and the continuation of relationships. Using a new paradigm, this study quantifies discrepancies in how the severity of violence is communicated in texts written by offenders, victims, and bystanders who witness violence. The study was conducted in two phases…
Women Are Perceived to Have More Power Than Men in Domains That Are Viewed As Important in U.S. Tweets
Previous research of gender differences in power has largely focused on the public domain (e.g., leadership positions), and to a lesser extent power on the private domain (e.g., power in private relationships), where people may perceive these domains to be more or less important in their lives. We studied gender differences in preference weighted power (PWP) in different domains by weighting the perceived power by the perceived importance in life…
Psychometric properties of persian version of escapism scale among Iranian adolescents
The aim of this study was to assess the psychometric properties of the Persian version of the Escapism Scale among Iranian adolescents aged 14-18. Between January 2021 and August 2021, cross-sectional study was conducted using a convenience sampling method to select 566 participants (340 girls and 226 boys) to investigate the relationship between physical activity and mental health in adolescents. The participants completed several questionnaires…
Voters’ view of leaders during the Covid‐19 crisis: Quantitative analysis of keyword descriptions provides strength and direction of evaluations
Objectives: Previous research suggests that governments usually gain support during crises such as the Covid-19. However, these findings are based on rating scales that only allow us to measure the strength of this support. This article proposes a new measure of how voters evaluate Prime Ministers (PM) by asking for descriptive keywords that are analyzed by natural language processing. Methods: By collecting a representative sample of citizens' o…
Self-perception and interpersonal peacefulness: The mediating role of theory of mind and harmony
Purpose A wide range of variables, including cognitive, emotional and relational factors, could affect the level of peacefulness. The purpose of this paper is to examine key variables (theory of mind (ToM) and harmony) that mediate the personality trait of peacefulness. Design/methodology/approach The participants were 182 university students recruited from three universities in Isfahan, Iran. Some different scales were applied in order to measur…
Latent Semantic Analysis Discriminates Children with Developmental Language Disorder (DLD) from Children with Typical Language Development
Computer based analyses offer a possibility for objective methods to assess semantic-linguistic quality of narratives at the text level. The aim of the present study is to investigate whether a semantic language impairment index (SELIMI) based on latent semantic analysis (LSA) can discriminate between children with developmental language disorder (DLD) and children with typical language development. Spoken narratives from 54 children with DLD and…
The big two dictionaries: Capturing agency and communion in natural language
Four studies developed and validated two dictionaries to capture agentic and communal expressions in natural language. Their development followed the Linguistic Inquiry and Word Count ( LIWC ) approach (Study 1) and we tested their validity with frequency‐based analyses and semantic similarity measures. The newly developed Agency and Communion dictionaries were aligned with LIWC categories related to agency and communion (Study 2), and correspond…
From I to We: Group formation and linguistic adaption in an online xenophobic forum
Much of identity formation processes nowadays takes place online, indicating that intergroup differentiation may be found in online communities. This paper focuses on identity formation processes in an open online xenophobic, anti-immigrant, discussion forum. Open discussion forums provide an excellent opportunity to investigate open interactions that may reveal how identity is formed and how individual users are influenced by other users. Using …
The A(ffective) B(ehavioral) C(ognitive) of Taboo Words in Natural Language: The Relationship Between Taboo Words' Intensity and Frequency
We investigated the relationship between the affective component (A: the level of offensiveness/intensity) and the behavioral component (B: the frequency of usage) of taboo words that are part of an individual's natural language (C: the cognitive component). In Study 1, 900 U.S. residents generated the 10 most common taboo words they use in their daily lives (C). In Study 2, 1,000 U.S. residents were presented with the 30 most common taboo words …

She” and “He” in News Media Messages: Pronoun Use Reflects Gender Biases in Semantic Contexts
Biases in News Media as Reflected by Personal Pronouns in Evaluative Contexts
This paper examines whether pronouns in news media occurred in evaluative contexts reflecting psychological biases. Contexts of pronouns were measured by computerized semantic analysis. Results showed that self-inclusive personal pronouns (We, I) occurred in more positive contexts than self-exclusive pronouns (He/She, They), reflecting self- and group-serving biases. Contexts of collective versus individual pronouns varied; We occurred in more po…
Selection Bias in Choice of Words: Evaluations of “I” and “We” Differ Between Contexts, but “They” Are Always Worse
In everyday life, people use language to communicate evaluative messages about social categories. A selection bias in language across two social dimensions not previously integrated was examined: a self-inclusive/self-exclusive dimension and an individual/collective dimension. Pronouns as markers for social categories were adopted ( I, We, He/She, and They), and a new measure was developed (the Evaluative Sentence Generating task) to investigate …
Choice Blindness and Preference Change: You Will Like This Paper Better If You (Believe You) Chose to Read It
Choice blindness is the finding that participants both often fail to notice mismatches between their decisions and the outcome of their choice and, in addition, endorse the opposite of their chosen alternative. But do these preference reversals also carry over to future choices and ratings? To investigate this question, we gave participants the task of choosing which of a pair of faces they found most attractive. Unknown to them, we sometimes use…

Failure to Detect Mismatches Between Intention and Outcome in a Simple Decision Task
A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly manipulated the relationship between choice and ou…
