The Influence of Expertise and Language Proficiency on Lie Truth Detection and Truth Bias in the Legal System
The present study examined how professional expertise and language proficiency affect lie‐truth detection accuracy and truth bias in a legal context by comparing experts (court judges, prosecutors, lawyers; n = 97) with laypersons ( n = 95). To this end, a preregistered mixed‐design online study was conducted in which participants judged the credibility of 16 video messages delivered by native and non‐native German speakers in an interrogation si…
How multiple motives facilitate decisions to exercise in contexts with tempting alternatives
OBJECTIVE: Both affectively-charged and reflective motivation may be necessary to sustain recommended physical activity (PA) guidelines, especially in contexts with tempting alternatives. However, our understanding of how different sources of motivation facilitate PA across contexts is limited. This paper presents a novel value-based model that specifies how affectively-charged and reflective motivation interact to support PA decisions based on a…
A new measure of regulatory focus
OBJECTIVE AND BACKGROUND: The goals of this project were to improve our understanding of chronic regulatory focus constructs and to provide researchers with a measure that adequately assesses the constructs, can distinguish individual differences effectively across the range of the constructs, and is appropriate for use in diverse populations. METHOD: Employing best practices in construct validation, we developed the International Personality Ite…
Psychological network analysis of the relations between beliefs about smoking for smokers with and without a recent quit attempt
OBJECTIVE: Psychological network analysis was used to evaluate the relations between beliefs about cigarette smoking in current smokers with and without a recent quit attempt and determine if these networks differed in global strength (how strongly beliefs are related) or global structure (which beliefs are related). DESIGN: = 7855), we evaluated differences in global strength and global structure of the beliefs held by current smokers with and w…
Is It the Judge, the Sender, or Just the Individual Message? Disentangling Person and Message Effects on Variation in Lie-Detection Judgments
Research suggests that people differ more in their ability to lie than in their ability to detect lies. However, because studies have not treated senders and messages as separate entities, it is unclear whether some senders are generally more transparent than others or whether individual messages differ in their transparency of veracity regardless of senders. Variance attributable to judges, senders, and messages was estimated simultaneously usin…
Contextual disruption and exercise
OBJECTIVE: This study examines the impact of COVID-19 restrictions on exercise routines and engagement in moderate-vigorous physical activity (MVPA). DESIGN: = 397) who reported meeting recommended guidelines for MVPA prior to COVID-19 completed an online questionnaire during the United States' COVID-19 lockdowns in April/May 2020. MAIN OUTCOME MEASURES: Participants reported their MVPA currently and before COVID-19, and answered questions about …
Is the uncertain self good at detecting lies? The influence of personal uncertainty on deception detection
Five experiments (total number of judging participants = 1309, four different kinds of stimulus materials with a total of 464 messages, total number of judgements = 19,634) investigated the influence of personal uncertainty on the process of lie detection in social relationships. Building on and extending basic assumptions of uncertainty management models, we reasoned that uncertainty about themselves motivates people to evaluate the quality of t…
Psychological Science in the Wake of Covid-19
The COVID-19 pandemic has extensively changed the state of psychological science from what research questions psychologists can ask to which methodologies psychologists can use to investigate them. In this article, we offer a perspective on how to optimize new research in the pandemic’s wake. Because this pandemic is inherently a social phenomenon—an event that hinges on human-to-human contact—we focus on socially relevant subfields of psychology…
Psychological Correlates of Perceived Physical Activity Engagement During the Covid-19 Pandemic Among Previously Active Individuals
The COVID-19 pandemic altered daily life in the United States and disrupted how people engage in routine health behaviors, such as physical activity (PA). This study investigates factors that may have helped people sustain recommended levels of moderate to vigorous PA (MVPA) during this time. Using a cross-sectional design, we recruited from Amazon's Mechanical Turk in April/May 2020 a sample of individuals who reported that they had met recommen…
