Recently, misinformation has increasingly impacted public discourse and public safety. From the COVID-19 pandemic to national elections, society is increasingly examining the negative impact of misinformation. Exposure to misinformation has been linked to conflicting perceptions of social, economic, and political issues, which leads to polarization, radicalization, and even acts of violence. While research has examined the development and spreading of misinformation, little has been done to examine the processes of being exposed to, and influenced by, misinformation. This paper uses Reinforcement Sensitivity Theory to examine the effect of individual differences in personality traits related to the behavioral inhibition system on the behavioral and cognitive response to exposure to misinformation online. Trait BIS was related to how much individuals positively engaged with misinformation, as well as intentions for activism and radicalism. These findings suggest that high uncertainty/anxiety may increase engagement with and influence by misinformation.

Bridging Classical and Revised Reinforcement Sensitivity Theory Research: A Longitudinal Analysis of a Large Population Study

The reinforcement sensitivity theory (RST) proposes that neurobiological systems mediate protective and appetitive behaviours and the functioning of these systems is associated to personality traits. In this manner, the RST is a link between neuroscience, behaviour, and personality. The theory evolved to the present revised version describing three systems: fight-flight-freezing, behavioural approach/activation (BAS), and behavioural inhibition (BIS). However, the most widely available measure of the theory, the BIS/BAS scales, only investigates two systems. Using a large longitudinal community survey, we found that the BIS/BAS scales can be re-structured to investigate the three systems of the theory with a BIS scale, three BAS scales, and a separate fight-flight-freezing system (FFFS) scale. The re-structured scales were age, sex, and longitudinally invariant, and associations with personality and mental health measures followed theoretical expectations and previously published associations. The proposed framework can be used to investigate behavioural choices influencing physical and mental health and bridge historical with contemporary research.

Pengembangan Model Perilaku Mengebut di Indonesia serta Rekomendasi Pencegahannya

Menurut data dari Kepolisian Republik Indonesia, 61% kasus terjadinya kecelakaan adalah karena faktor manusia. Kementerian Perhubungan (Kemenhub) juga mencatat bahwa sedikitnya 2-3 orang meninggal dunia per harinya akibat kecelakaan lalu lintas dimana pada posisi pertama kecelakaan disebabkan oleh pengendara sepeda motor. Land Transport Safety Authority (LTSA) pada tahun 2001 juga menemukan bahwa mengebut (speeding) menjadi faktor utama dalam kematian pengendara kendaraan bermotor. Oleh karena itu, perlu dilakukannya penelitian yang dapat mengungkapkan faktor-faktor yang mempengaruhi perilaku mengebut sehingga mekanisme pencegahan perilaku tersebut dapat dibuat. Sebuah kuesioner dikembangkan sebagai instrumen penelitian berdasarkan Theory of Planned Behaviour (TPB), Drivers Behaviour Questionnaire (DBQ), Classical Deterrence Theory (CDT) dan Revised Reinforcement Sensitivity Theory (r-RST). Terdapat 317 responden yang mengisi kuesioner tersebut. Metode analisis yang digunakan untuk mengolah data tersebut adalah dengan menggunakan Partial Least Square Structural Equation Modelling (PLS-SEM). Hasil dari 317 pengendara di Indonesia menunjukkan bahwa Perceived Behavioural Control (PBC) merupakan variabel yang paling mempengaruhi niat seseorang untuk melakukan perilaku mengebut. Sehingga, salah satu rekomendasi pencegahan berdasarkan hasil tersebut adalah dengan memberikan hambatan agar pengendara tidak merasa termotivasi untuk melakukan perilaku mengebut.

Are reinforcement sensitivity personality constructs and attentional control important predictors of restrictive disordered eating?

The revised Reinforcement Sensitivity Theory (rRST) perspective on personality suggests that a neuropsychological behavioural inhibition system (BIS), behavioural approach system (BAS), and a fight-flight-freeze system (FFFS) produce the key personality traits involved in approach and avoidance behaviours. This perspective on personality can be used as a framework for understanding psychopathology. Self-report research on rRST suggests that restrictive disordered eating relates to elevated BIS sensitivity, elevated FFFS sensitivity, and possibly dysfunctional BAS sensitivity. Disordered eating can also relate to reduced trait mindfulness, which is a broadly defined construct. Trait mindfulness is positively correlated with attentional control (AC) which is a more specific component of our cognitive architecture that incorporates attentional focusing and attentional shifting processes. It is unknown how BIS and AC interact to predict restrictive disordered eating. We tested how self-reported BIS, BAS, and FFFS sensitivity, AC, and trait mindfulness relate to restrictive disordered eating in 464 healthy participants, and 177 participants with a history of psychiatric disorder. We provide new evidence that elevated restrictive disordered eating relates to reduced self-reported AC abilities (in addition to elevated BIS, and elevated FFFS sensitivity). We illustrate that the combination of high BIS and low AC predicts high levels of restrictive disordered eating (but not in all participants), whereas low BIS and high AC predicts lower levels of restrictive disordered eating (but not in all participants). We discuss how understanding the relationship between personality and attentional control can inform the design of future intervention studies.

Emotional and Behavioral Responses to COVID-19

This review appraises evidence for the role of personality in COVID-19 related emotions and behaviors. Three key models of personality are considered: the Five-factor Model, HEXACO model, and Reinforcement Sensitivity Theory (RST). In line with personality research, more generally, most studies focus on the Five-Factor model. Key findings are that neuroticism is most associated with poor mental health, and extraversion is associated with a reluctance to socially isolate. Conscientiousness predicts compliance with safety guidelines but also with fewer prosocial behaviors, particularly stockpiling. Research within the HEXACO framework largely confirms these findings, especially for emotionality and mental health. The additional HEXACO Honesty-Humility factor is found to be associated with prosocial views and abstention from panic buying. Studies based on the Reinforcement Sensitivity Theory of personality indicate emotional conflict as people wish to stay safe while maintaining a sense of normality. Behavioral compliance is driven by activation in the Fight-Flight-Freeze System (FFFS; fear-related) and the Behavioral Inhibition System (BIS; anxiety-related). The Behavioral Approach System (BAS) is implicated in approach-driven behaviors such as avoiding infection. These findings have implications for health communications and post-pandemic support.

ERP Indicators of Self-Pain and Other Pain Reductions due to Placebo Analgesia Responding: The Moderating Role of the Fight-Flight-Freeze System

This study evaluates the modulation of phasic pain and empathy for pain induced by placebo analgesia during pain and empathy for pain tasks. Because pain can be conceptualized as a dangerous stimulus that generates avoidance, we evaluated how approach and avoidance personality traits modulate pain and empathy for pain responses. We induced placebo analgesia to test whether this also reduces self-pain and other pain. Amplitude measures of the N1, P2, and P3 ERPs components, elicited by electric stimulations, were obtained during a painful control, as well as during a placebo treatment expected to induce placebo analgesia. The placebo treatment produced a reduction in pain and unpleasantness perceived, whereas we observed a decrease in the empathy unpleasantness alone during the empathy pain condition. The moderator effects of the fight-flight-freeze system (FFFS) in the relationships linking P2 and P3 amplitude changes with pain reduction were both significant among low to moderate FFFS values. These observations are consistent with the idea that lower FFFS (active avoidance) scores can predict placebo-induced pain reduction. Finally, in line with the revised Reinforcement Sensitivity Theory (r-RST), we can assume that phasic pain is an aversive stimulus activating the active-avoidance behavior to bring the system back to homeostasis.
