Basic Psychological Needs Are Associated With Engagement and Hate Term Use in Extremist Chatrooms
Extremist groups frequently leverage online spaces in recruitment and organization efforts. This research assessed how basic psychological need expression among users of extremist chatrooms was related to forum engagement and hate term use. ∼20,000,000 posts from ∼90,000 users on 233 Discord chatrooms were scraped from a publicly available database. Using a natural language processing approach, users received scores on three needs based on semant…
The Role of Basic Psychological Needs in Right-Wing Extremism Risk Among American Conservatives
Modern psychological theories of violent extremism stress the roles of social connections and personal meaning as motivators for individuals to participate in extremist groups. Personal meaning and social connections are both important aspects of Basic Psychological Needs Theory, a motivation framework commonly used in workplace and educational psychology. This study sought to assess the relationship between Basic Psychological Needs and extremis…
Sex robots and personality
A Scoring Procedure for Malignant Narcissism Based on Personality Inventory for DSM-5 Facets
The current study focuses on the development and validation of a scoring procedure for malignant narcissism using the Personality Inventory for DSM-5, a self-report measure of Criterion B from the Alternative Model for Personality Disorders. In Study 1, a prototype matching approach was used to aggregate ratings from 15 clinicians specializing in personality disorder treatment and/or assessment. Indices of inter-rater agreement and inter-rater re…
Perceived stigma and erotic technology
The intersection of technology and sexuality in sex toys and erobots – artificial erotic agents (e.g. sex robots) – may generate stigma with their use. However, despite the growing prevalence of technology in human sexuality, researchers have yet to examine this stigma. Hence, this study provides the first quantitative evidence of perceived stigma related to erotic technology use (PSETU) and its association with people’s willingness to engage wit…
Hot for Robots! Sexual Arousal Increases Willingness to Have Sex with Robots
Robots designed to elicit sexual arousal are coming. Sexual arousal can increase our willingness to engage in risky or unconventional sexual behaviors. However, researchers have yet to examine whether this effect extends to robots. Hence, this study provides the first empirical evidence that state sexual arousal can increase our willingness to engage erotically with robots. Based on previous research, we hypothesized that levels of sexual arousal…
A Comparison of Limited-Information Test Statistics for a Response Style Mirt Model
An increased use of models for measuring response styles is apparent in recent years with the multidimensional nominal response model (MNRM) as one prominent example. Inclusion of latent constructs representing extreme (ERS) or midpoint response style (MRS) often improves model fit according to information criteria. However, a test of absolute model fit is often not reported even though it could comprise an important piece of validity evidence. L…
Assessment of the Harmful Psychiatric and Behavioral Effects of Different Forms of Child Maltreatment
Our findings challenge widely held beliefs about how child abuse should be recognized and treated-a responsibility that often lies with the physician. Because different types of child abuse have equivalent, broad, and universal effects, effective treatments for maltreatment of any sort are likely to have comprehensive psychological benefits. Population-level prevention and intervention strategies should emphasize emotional abuse, which occurs wit…
The effects of racial heterogeneity on mental health
A majority of detained adolescents experience mental health and substance use problems. Limited research has examined the interaction between the race/ethnicity of an individual youth and county-level racial heterogeneity on adolescent mental health outcomes. Participants were identified through a statewide mental health screening project that took place in detention centers across 11 different counties in a Midwestern state during January 1, 200…
The (non)relation between empathy and aggression
Assumptions regarding the importance of empathy are pervasive. Given the impact these assumptions have on research, assessment, and treatment, it is imperative to know whether they are valid. Of particular interest is a basic question: Are deficits in empathy associated with aggressive behavior? Previous attempts to review the relation between empathy and aggression yielded inconsistent results and generally included a small number of studies. To…
