Background Mental health (MH) peer online forums offer robust support where internet access is common, but healthcare is not, e.g., in countries with under-resourced MH support, rural areas, and during pandemics. Despite their widespread use, little is known about who posts in such forums, and in what mood states. The discussion platform Reddit is...

Background Emotion dysregulation is a characteristic central to borderline personality disorder (BPD). Valuably, verbal behaviour can provide a unique perspective for studying emotion dysregulation in BPD, with recent research suggesting that the varieties of emotion words one actively uses (i.e., active emotion vocabularies [EVs]) reflect habitual...

During the Covid-19 pandemic, the global public has relied on their political leaders toguide them through the crisis. The current study investigated if and how political leader’srhetoric would be associated with collective emotional responses. We used text analyticalmethods to investigate association between political leader speech and daily aggre...

Borderline personality disorder (BPD) is characterized by severe interpersonal dysfunction, yet the underlying nature of such dysfunction remains poorly understood. The present study adopted a behavioral approach to more objectively describe the social-cognitive contributors to interpersonal dysfunction in BPD. Participants (N = 530) completed an o...

Background Despite its growing prevalence, BDSM practice (bondage, discipline, dominance, submission, and sadomasochism) is still stigmatized, and little is known about the physical marks and injuries that individuals sustain from consensual BDSM-related activities. Aim In this exploratory study, we examined BDSM sexual experiences and the physica...

The stereotypes and biases that people have about various religions may not be applied to just the individuals who belong to those religions, but to the belief systems themselves. We hypothesized that non-Muslim and Muslim Americans would demonstrate biased estimates about the language content of the Quran and New Testament holding positive views t...

Reddit discourse surrounding treatments for autistic individuals is easily accessible. Multiple Reddit threads discuss Applied Behavior Analysis (ABA) as one option. Such content impacts decision-making despite the absence of gatekeeping mechanisms to identify misinformation. Using a cross-sectional design, this study explores perceptions of ABA-ba...

Unlabelled: Emotional granularity is the ability to create differentiated and nuanced emotional experiences and is associated with positive health outcomes. Individual differences in granularity are hypothesized to reflect differences in emotion concepts, which are informed by prior experience and impact current and future experience. Greater vari...

While experiencing the unpredictable events of the COVID-19 pandemic, we are likely to turn to people in order to regulate our emotions. In this research, we investigate how this interpersonal emotion regulation is connected to affective symptoms, above and beyond intrapersonal emotion regulation. Furthermore, we explore whether perceived psychosoc...

Some scholars have presented models of the United States as a set of “nations” with distinct settlement histories and contemporary cultures. We examined personality differences in one such model, that of Colin Woodard, using data from over 75,000 respondents. Four nations were particularly distinct: The Deep South, Left Coast, New Netherland, and t...

Despite the established health and ecological benefits of a plant-based diet, the decision to eschew meat and other animal-derived food products remains controversial. So polarising is this topic that anti-vegan communities - groups of individuals who stand vehemently against veganism - have sprung up across the internet. Much scholarship on vegani...

Linguistic features of a message necessarily shape its persuasive appeal. However, studies have largely examined the effect of linguistic features on persuasion in isolation and do not incorporate properties of language that are often involved in real-world persuasion. As such, little is known about the key verbal dimensions of persuasion or the re...

This article examines how verbal authenticity influences person perception. Our work combines human judgments and natural language processing to suggest verbal authenticity is a positive predictor of interpersonal interest (Study 1: 294 dyadic conversations), engagement with speeches (Study 2: 2,655 TED talks), entrepreneurial success (Study 3: 478...

Recent years have seen an explosion of interest in the use of computerized text analysis methods to address basic psychological questions.

The words that people use in everyday life tell us about their psychological states: their beliefs, emotions, thinking habits, lived experiences, social relationships, and personalities. From the time of Freud’s writings about “slips of the tongue” to the early days of computer-based text analysis, researchers across the social sciences have amasse...

Emotional granularity is the ability to create differentiated and nuanced emotional experiences and is associated with positive health outcomes. Individual differences in granularity are hypothesized to reflect differences in emotion concepts, which are informed by prior experience and impact current and future experience. Greater variation in expe...

The mental health of college students is a growing concern, and gauging the mental health needs of college students is difficult to assess in real-time and in scale. To address this gap, researchers and practitioners have encouraged the use of passive technologies. Social media is one such "passive sensor" that has shown potential as a viable "pass...

Background: It is critical for professionals to understand the discourse landscape within various online and social media outlets in order to support families of children with autism in treatment decision-making. This need is heightened when considering treatments that have garnered excitement and controversy, such as applied behavioral analysis (A...

Today, the development of new technologies means that there are many advanced tools that can be used to improve our understanding of personality disorder, and, in turn, the treatment of personality disorder. One particularly promising tool — indeed, the focus of this chapter — is computerized language analysis. Through the exploration and analysis...

We compare the contents of Fox and MSNBC weekday evening telecasts using natural language analysis with the Linguistic Inventory Word Count (LIWC) and sociopolitical dictionaries tapping into moral foundations, values, grievances, and personality. Across time, the two networks differed substantially across many constructs, particularly those from t...

Objective The primary aim of the study was to examine the automated linguistic analysis of the open-ended problem (PQ) and life-effects (LEQ) questionnaires to understand the psychological effects of tinnitus.

While language style is considered to be automatic and relatively stable, its plasticity has not yet been studied in translations that require the translator to “step into the shoes of another person.” In the present study, we propose a psychological model of language adaptation in translations. Focusing on an established interindividual difference...

Computational methods for the representation and analysis of data have drastically increased the objectivity, reliability, and the practical implications of research conducted throughout most scientific pursuits. Our rapidly-emerging potential to transform digital data into objective measures of human behavior, thoughts, and feelings has perfectly...

Psychologists have long believed that we can discern what makes a person tick by analysing their language. The modern study of language has become a highly sophisticated area of research that leverages computational modelling, objective measures of language, and extensive empirical rigor. The links between a person’s mental processes and the words...

Throughout history, scholars and laypeople alike have believed that our words contain subtle clues about what we are like as people, psychologically speaking. However, the ways in which language has been used to infer psychological processes has seen dramatic shifts over time and, with modern computational technologies and digital data sources, we...

The huge power for social influence of digital media may come with the risk of intensifying common societal biases, such as gender and age stereotypes. Speaker’s gender and age also behaviorally manifest in language use, and language may be a powerful tool to shape impact. The present study took the example of TED, a highly successful knowledge dis...

The unique ways in which people use language can reveal a great deal about their personality. Research has found language to be a valid and reliable mode of measuring and understanding personality, and various methods of analysis allow researchers to explore how personality is encoded in the way that people use language.

To date we know little about natural emotion word repertoires, and whether or how they are associated with emotional functioning. Principles from linguistics suggest that the richness or diversity of individuals' actively used emotion vocabularies may correspond with their typical emotion experiences. The current investigation measures active emoti...

Estimating psychological constructs from natural language has the potential to expand the reach and applicability of personality science. Research on the Big Five has produced methods to reliably assess personality traits from text, but the development of comparable tools for personal values is still in the early stages. Based on the Schwartz theor...

Personality psychology has long been grounded in data typologies, particularly in the delineation of behavioural, life outcome, informant-report, and self-report sources of data from one another. Such data typologies are becoming obsolete in the face of new methods, technologies, and data philosophies. In this article, we discuss personality psycho...

It is often assumed that people who use rich emotional vocabularies are emotionally healthier than those who express themselves using a narrower range of emotion words. However, the relevant research relies on passive presentation of experimenter-generated emotion words. To date we know little about natural emotion word repertoires, and whether or...

Background: To help shed light on the peculiar circumstances surrounding the death of the famed macabre and mystery writer, poet, editor, and literary critic, we explored the potential role of depression in the life and death of Edgar Allan Poe via his written language. Method: Using computerized language analysis, we analyzed works from Poe’s co...

On 11 February 2015, a 20-year-old university student, Ozgecan Aslan, was violently murdered in an attempted rape in Mersin, southern Turkey. This event led to a mass Twitter protest in the country. Women across the country started sharing the hashtag #sendeanlat (“#tellyourstory” in English). In the current exploratory study, 164,279 original twee...

Do in-class discussion groups lead to improved learning for individual group members? Analyses of over 1600 students’ language samples from 4800+ online discussion groups revealed that markers of linguistic engagement were highly predictive of academic outcomes.

There are several domains that are ripe for scientists to begin comparing notes and piecing together a uniform, coherent perspective on how generalized motivational systems emerge, function, and are shaped by their inputs. Becker and Neuberg repeatedly raise language learning and acquisition as an important exemplar that is simultaneously reflectiv...

Low resting heart rate variability (HRV) has been associated with poor sexual arousal function in women. In a recent study, a single session of autogenic training increased HRV and facilitated improvements in both sexual arousal and perceived genital sensations among women experiencing decreased arousal. The current study expands upon these finding...

Converging investigations on the part of multiple agencies/agents have provided overwhelming evidence for Russian interference in the 2016 U.S. presidential election. As a part (and consequence) of recent reports, multiple datasets that capture actions taken by actors of the Internet Research Agency (IRA), have been released to the public. In the c...

Many individuals who experience nonconsensual sexual experiences (NSEs) do not identify their experiences with common sexual violence labels (e.g., sexual assault, rape, or abuse), and cognitive mechanisms of identification have yet to be examined. Identification may involve the integration of the experience into sexual self-schemas, which would ha...

Modern authorship attribution methods are often comprised of powerful yet opaque machine learning algorithms. While much of this work lends itself to concrete outcomes in the form of probability scores, advanced approaches typically preclude deeper insights in the form of psychological interpretation. Additionally, few attribution methods exist for...
