The relation between belief in a just world and early processing of deserved and undeserved outcomes: An ERP study

ABSTRACT We used event-related potentials (ERPs) to examine how quickly people in general, and certain people in particular, process deservingness-relevant information. Female university students completed individual difference measures, including individual differences in the belief in a just world (BJW), a belief that people get what they deserve. They then read stories in which an outcome was deserved, undeserved, or neither deserved nor undeserved (i.e., “neutral”) while their ERPs were recorded with scalp electrodes. We found no overall differentiation between early ERP responses (<300 ms post-stimulus onset) to deserved, undeserved, and neutral outcomes. However, BJW correlated with the difference between early ERP responses to these forms of information (rs from |.44| to |.61|; ps from .018 to < .001). The early nature of our effects (e.g., 96 ms after stimulus onset) suggests individual differences in socially-relevant information processing that begins before conscious evaluation of the stimuli. Potential underlying processes include automatic attention to schema-relevant information and to unexpected (and therefore salient) information and automatic processing of belief-consistent information. Our research underscores the importance of the concept of deservingness in human information processing as well as the utility of ERP technology and robust statistical analyses in investigations of complex social stimuli.

The Interpersonal Dimension of Pandemic Fear and the Dual-Factor Model of Mental Health: The Role of Coping Strategies.

(1) Background: Current COVID-19 research has mainly focused on negative outcomes associated with fear of the pandemic with the examination of potentially positive outcomes remaining underexplored. Based on the dual-factor model of mental health, which postulates positive and negative dimensions, we assessed the influence of COVID-19 fear on both negative and positive mental health outcomes and examined the mediational role of coping strategies. (2) Methods: A convenience sample of 231 respondents participated in an online survey reporting on measures of pandemic fear (SFS), distress (HADS), post-traumatic growth (PTGI) and individual differences in terms of coping strategies (CSI-SF). (3) Results: Respondents’ main concerns related with the pandemic highlighted the interpersonal and social dimensions implicated in fear of COVID-19. As expected, fear of the pandemic was associated not just with negative but also positive outcomes, while different coping strategies played a role in determining such effects. More specifically, disengagement coping mediated the effects of fear on anxiety and depression, whereas engagement coping was the only mediator of the relationship between COVID-19 fear and post-traumatic growth. (4) Conclusions: Approaches to promote psychological wellbeing in the context of the COVID-19 pandemic should on the one hand be sensitive to the needs of the more vulnerable population groups, while on the other leverage existing resources to harness the potential for growth. Strengthening engagement coping in the context of fears triggered by the pandemic may constitute a valuable target to protect against negative and optimize positive mental health outcomes in the general population.

Self-reflection, insight, and mood disorder symptoms: Evaluating the short form of the self-reflection and insight scale with clinical interviews and self-reports

The 20-item Self-reflection and Insight Scale (SRIS) is a widely used measure of individual differences in self-focused attention and private self-consciousness. In the present research, we examined the validity of a 12-item short form of the SRIS, which was recently developed based on item response theory models. Measures related to mental health and well-being were used as criteria for evaluating the relative effect sizes for the long and short SRIS. In Study 1 (n = 278 adults), the short and long SRIS scores had highly similar correlations with dimensional measures of depression, anxiety, and stress symptoms as well as with neuroticism. In Study 2 (n = 78 adults), participants were classified into major depression and healthy control groups based on structured clinical interviews. The short and long SRIS had similar profiles of differences between the two groups. Taken together, the studies suggest that the short forms effectively recover the effect sizes of the long forms, so the briefer SRIS would be a good option when time and survey space are tight.

Disproven but still believed: The role of information and individual differences in the prediction of topic‐related pseudoscience acceptance

AbstractThe spread of pseudoscience (PS) is a worrying problem worldwide. The study of pseudoscience beliefs and their associated predictors have been conducted in the context of isolated pseudoscience topics (e.g., complementary and alternative medicine). Here, we combined individual differences (IIDD) measures (e.g., personality traits, thinking styles) with measures related with the information received about PS: familiarity and disproving information (DI) in order to explore potential differences among pseudoscience topics in terms of their associated variables. These topics differed in their familiarity, their belief rating, and their associated predictors. Critically, our results not only show that DI is negatively associated with pseudoscience beliefs but that the effect of various IIDD predictors (e.g., analytic thinking) depends on whether DI had been received. This study highlights the need to control for variables related to information received about pseudoscientific claims to better understand the effect of other predictors on different pseudoscience beliefs topics.

Measuring Spatial Perspective Taking: Analysis of Four Measures Using Item Response Theory.

Research on spatial thinking requires reliable and valid measures of individual differences in various component skills. Spatial perspective taking (PT)-the ability to represent viewpoints different from one's own-is one kind of spatial skill that is especially relevant to navigation. This study had two goals. First, the psychometric properties of four PT tests were examined: Four Mountains Task (FMT), Spatial Orientation Task (SOT), Perspective-Taking Task for Adults (PTT-A), and Photographic Perspective-Taking Task (PPTT). Using item response theory (IRT), item difficulty, discriminability, and efficiency of item information functions were evaluated. Second, the relation of PT scores to general intelligence, working memory, and mental rotation (MR) was assessed. All tasks showed good construct validity except for FMT. PPTT tapped a wide range of PT ability, with maximum measurement precision at average ability. PTT-A captured a lower range of ability. Although SOT contributed less measurement information than other tasks, it did well across a wide range of PT ability. After controlling for general intelligence and working memory, original and IRT-refined versions of PT tasks were each related to MR. PTT-A and PPTT showed relatively more divergent validity from MR than SOT. Tests of dimensionality indicated that PT tasks share one common PT dimension, with secondary task-specific factors also impacting the measurement of individual differences in performance. Advantages and disadvantages of a hybrid PT test that includes a combination of items across tasks are discussed.

Examining Effort in 1D Uncertainty Communication Using Individual Differences in Working Memory and NASA-TLX

As uncertainty visualizations for general audiences become increasingly common, designers must understand the full impact of uncertainty communication techniques on viewers' decision processes. Prior work demonstrates mixed performance outcomes with respect to how individuals make decisions using various visual and textual depictions of uncertainty. Part of the inconsistency across findings may be due to an over-reliance on task accuracy, which cannot, on its own, provide a comprehensive understanding of how uncertainty visualization techniques support reasoning processes. In this work, we advance the debate surrounding the efficacy of modern 1D uncertainty visualizations by conducting converging quantitative and qualitative analyses of both the effort and strategies used by individuals when provided with quantile dotplots, density plots, interval plots, mean plots, and textual descriptions of uncertainty. We utilize two approaches for examining effort across uncertainty communication techniques: a measure of individual differences in working-memory capacity known as an operation span (OSPAN) task and self-reports of perceived workload via the NASA-TLX. The results reveal that both visualization methods and working-memory capacity impact participants' decisions. Specifically, quantile dotplots and density plots (i.e., distributional annotations) result in more accurate judgments than interval plots, textual descriptions of uncertainty, and mean plots (i.e., summary annotations). Additionally, participants' open-ended responses suggest that individuals viewing distributional annotations are more likely to employ a strategy that explicitly incorporates uncertainty into their judgments than those viewing summary annotations. When comparing quantile dotplots to density plots, this work finds that both methods are equally effective for low-working-memory individuals. However, for individuals with high-working-memory capacity, quantile dotplots evoke more accurate responses with less perceived effort. Given these results, we advocate for the inclusion of converging behavioral and subjective workload metrics in addition to accuracy performance to further disambiguate meaningful differences among visualization techniques.

Emotional Sensitivity to Probability as a Predictor of COVID-19 Vaccine Hesitancy and Prevention Behaviors

Any path out of the COVID-19 crisis will depend heavily on widespread vaccination, but substantial vaccine hesitancy and refusal stand in the way of reaching that goal. The pre-COVID literature on vaccine hesitancy points to several important factors, but important features of this pandemic may be uniquely contributing to hesitancy specifically for this vaccine. This pandemic has been characterized by unprecedented access to real-time risk statistics, such as positivity rates and case counts, and interpretations of those numbers may help account for individual differences in how people respond to the virus. In a survey of college students, we measured participants’ intention to pursue the vaccine, their adherence to guidelines like masking and social distancing, and their worry about both the virus and the vaccine. We modeled these responses using a measure of emotional sensitivity to probability (ESP; the extent to which individuals calibrate their emotional responses to changes in risk probability) as well as 3 other individual difference measures for emotional reactivity to possibility (ERP), aversion to ambiguity in medicine (AAMed), and medical maximizing-minimizing (MMM). We found that ESP significantly predicted greater vaccine intention, β = .29, p = .003, and AAMed predicted less, β = –.25, p = .008. MMM predicted more frequent masking, β = .21, p = .02, social distancing, β = .22, p = .01, and avoidance of public places, β = .25, p = .006. ERP predicted worry about long-tern illness, β = .29, p &lt; .001, hospitalization, β = .25, p = .001, and death, β = .27, p &lt; .001, from COVID-19 but also predicted worry about side effects from the vaccine, β = .22, p = .006.

Creativity and Executive Function in School-Age Children: Effects of Creative Coloring and Individual Creativity on an Executive Function Sorting Task

We examined the relationship between executive function (EF) and creativity and whether a creative manipulation related to free coloring or coloring task-relevant materials would impact EF performance in the Dimensional Change Card Sort (DCCS). Participants also completed individual difference measures of creativity with an Alternative Uses Task and EF with a Backward Digit Span Working Memory Task and Delay of Gratification Inhibition Task. Although we failed to find a relationship between creativity in the Alternative Uses Task and our EF measures (rs &lt; .25, ps &gt; .10), we found evidence to suggest the effects of a creative color manipulation differed by individual differences in creativity. Those who were low in certain creative components like the ability to switch between categories (p = .03 and p = .08), generate a number of unique ideas (p = .03 and p = .04), and originality (p = .01) seemed to perform better when allowed to freely color before the DCCS compared to other conditions. Those who performed higher in creative measures generally did not benefit from a creative manipulation before the task. This suggests that a more nuanced examination of the relationship between creativity and EF considering possible experimental manipulations, multiple components, and individual differences may be useful in understanding the relationship between these 2 constructs.

Experimental evidence for expectation-driven linguistic convergence

This article examines the role of sociolinguistic expectations in linguistic convergence, using glide-weakened /aɪ/—a salient feature of Southern US English—as a test case. I present the results of two experiments utilizing a novel experimental paradigm for eliciting convergence—the wordnaming game task—in which participants read aloud (baseline) or hear (exposure) clues describing particular words and then give their guesses out loud. Participants converged toward a Southern-shifted model talker by producing more glide-weakened tokens of /aɪ/, without ever hearing the model talker produce this vowel. Participants in the control (Midland talker) condition exhibited no such response. Convergence was facilitated by both living in the South and producing less-weakened baseline /aɪ/ glides, but attitudinal and domain-general individual-differences measures did not reliably predict convergence behaviors. Results are discussed in terms of implications for the cognitive mechanisms underlying convergence behaviors and the mental representations of sociolinguistic knowledge.

The Effect of Perceived Uncertainty on Competitive Behavior

How do people behave in the face of uncertainty? Some studies suggest that even when they are unaware of how others will behave, people default to cooperative behavior; however, other research suggests that uncertainty leads to more competitive behavior. Little research has examined how individual differences moderate such behavioral decisions. This study proposes that a stable (dispositional) sense of justice may, ironically, lead to more competitive behavior. Specifically, people who score highly in belief in a just world, system justification, and religiosity, and low in ambiguity tolerance may be more inclined to compete rather than cooperate because they believe people who experience positive outcomes deserve those outcomes regardless of the means taken to achieve them. Across two studies, participants (N = 288) engaged in a prisoner’s dilemma game — a task where they must choose to compete or cooperate — and completed the aforementioned individual difference measures. Results show that people tended to cooperate, but those high in system justification and belief in a just world were more likely to compete. In other words, people with a strong sense of cosmic justice were likely to exhibit competitive behavior under uncertain conditions. KEYWORDS: Ambiguity Tolerance; Competition; Cooperation; Just World Beliefs; Prisoner’s Dilemma; Prosocial Behavior; Religiosity; System Justification; Uncertainty

National nostalgia and prostalgia predict support toward the Black Lives Matter movement and creating a new normal following the pandemic

AbstractThe Black Lives Matter (BLM) protests and the COVID‐19 pandemic are two distinct forces that have introduced cultural change around the world by respectively challenging or amplifying the status quo. Past research demonstrates that cultural change can be perceived as threatening. Thus, the change brought upon by the BLM movement and the pandemic may be reducing support toward the BLM movement and reducing support for creating a new normal following the pandemic (i.e., creating new social norms). Based on the Cultural Inertia Model, we predicted that highlighting the BLM protests and the COVID‐19 pandemic as agents of change would hinder support toward each agent of change. In essence, two agents of change might be too much change. We also hypothesized that national nostalgia and prostalgia would serve as psychological anchors or propellers that hinder or facilitate support toward each agent of change. Our findings demonstrated that highlighting the BLM protests and the pandemic as agents of change did not cause differences in support toward the BLM movement or creating a new normal. However, national nostalgia and prostalgia served as individual difference measures that respectively reduced and facilitated support toward the BLM movement and the creation of new social norms.

Susceptibility to COVID-19 Scams: The Roles of Age, Individual Difference Measures, and Scam-Related Perceptions.

As the COVID-19 pandemic was unfolding, a surge in scams was registered across the globe. While COVID-19 poses higher health risks for older adults, it is unknown whether older adults are also facing higher financial risks as a result of COVID-19 scams. Here, we examined age differences in vulnerability to COVID-19 scams and individual difference measures (such as impulsivity, ad skepticism, and past experiences with fraud) that might help explain them. A lifespan sample (M = 48.03, SD = 18.56) of sixty-eight younger (18–40 years, M = 25.67, SD = 5.93), 79 middle-aged (41–64 years, M = 49.86, SD = 7.20), and 63 older adults (65–84 years, M = 69.87, SD = 4.50) recruited through Prolific completed questions and questionnaires online. In a within-subjects design, each participant responded to five COVID-19 solicitations, psychological measures, and demographic questions. Age group comparisons revealed that older adults were marginally less likely to perceive COVID-19 solicitations as genuine than middle-aged adults were. In addition, older adults perceived significantly fewer benefits than both younger and middle-aged adults did and perceived marginally higher risks than younger adults did. Hence, older adults did not exhibit greater vulnerability to COVID-19 scams. Regardless of age, intentions to respond to COVID-19 solicitations were positively predicted by higher levels of educational attainment, being married, past fraud victimization, and higher levels of positive urgency. As expected, stronger genuineness and benefit perceptions positively predicted action intentions, whereas stronger risk perceptions negatively predicted action intentions As such, COVID-19 scam susceptibility appears to be the result of a impulse control issue that is not easily inhibited, not even by past experiences of scam victimization.

Individual Differences in Belief in Fake News about Election Fraud after the 2020 U.S. Election.

Fake news is a serious problem because it misinforms people about important issues. The present study examined belief in false headlines about election fraud after the 2020 U.S. presidential election. Belief in election fraud had dangerous consequences, including the deadly insurrection at the U.S. Capitol in January 2021. In the present study, participants rated the truthfulness of true and false headlines about the election, and then completed individual difference measures eight days after the election. Participants with more conservative ideology, greater presidential approval of the outgoing president, greater endorsement of general conspiracy narratives and poorer cognitive reflection demonstrated greater belief in false headlines about election fraud. Additionally, consuming more politically conservative election news was associated with greater belief in false headlines. Identifying the factors related to susceptibility to false claims of election fraud offers a path toward countering the influence of these claims by tailoring interventions aimed at decreasing belief in misinformation and decreasing conspiracy beliefs to those most susceptible.

Linking metaphor comprehension with analogical reasoning: Evidence from typical development and autism spectrum disorder.

We examined the relationship between metaphor comprehension and verbal analogical reasoning in young adults who were either typically developing (TD) or diagnosed with Autism Spectrum Disorder (ASD). The ASD sample was highly educated and high in verbal ability, and closely matched to a subset of TD participants on age, gender, educational background, and verbal ability. Additional TD participants with a broader range of abilities were also tested. Each participant solved sets of verbal analogies and metaphors in verification formats, allowing measurement of both accuracy and reaction times. Measures of individual differences in vocabulary, verbal working memory, and autistic traits were also obtained. Accuracy for both the verbal analogy and the metaphor task was very similar across the ASD and matched TD groups. However, reaction times on both tasks were longer for the ASD group. Additionally, stronger correlations between verbal analogical reasoning and working memory capacity in the ASD group indicated that processing verbal analogies was more effortful for them. In the case of both groups, accuracy on the metaphor and analogy tasks was correlated. A mediation analysis revealed that after controlling for working memory capacity, the inter-task correlation could be accounted for by the mediating variable of vocabulary knowledge, suggesting that the primary common mechanisms linking the two tasks involve language skills.

The reward positivity shows increased amplitude and decreased latency with increasing age in early childhood.

The reward positivity (RewP) is a widely studied measure of neural response to rewards, yet little is known about normative developmental characteristics of the RewP during early childhood. The present study utilized a pooled community sample of 309 4- to 6-year-old children who participated in the Doors guessing game to examine the latency and amplitude of the RewP. Peak detection of the gain-loss difference waveform was conducted for electrodes Fz, Cz, Pz, Oz and the mean activity in a 100ms window centered around this peak was analyzed. There was a significant decrease in RewP latency (RewP was earlier) and increase in RewP amplitude (RewP magnitude was larger) with advancing age in this cross-sectional analysis. Further, these were independent effects, as both RewP latency and RewP amplitude were uniquely associated with children's age. Moreover, our results indicate that the RewP latency in 4- to 6-year-olds falls outside the 250-350ms window typically used to quantify the RewP (RewP latency in our sample=381ms; SD=60.15). The internal consistency for latency (.64) and amplitude (.27) of the RewP were characterized by moderate to low reliability, consistent with previous work on the reliability of difference scores. Overall, results demonstrate RewP differences in both timing and amplitude across age in early childhood, and suggest that both amplitude and latency of the RewP might function as individual difference measures of reward processing. These findings are discussed in the context of methodological considerations and the development of reward processing across early childhood.

Internal consistency reliability of the P300 to novelty in infants: The influence of trial number and data loss due to artifacts

The P300 is an event-related potential component that reflects attention to motivationally salient stimuli and may be a promising tool to examine individual differences in cognitive-affective processing very early in development. However, the psychometric properties of the P300 in infancy are unknown, a fact that limits the component's utility as an individual difference measure in developmental research. To address this gap, 38 infants completed an auditory three-stimulus oddball task that included frequent standard, infrequent deviant, and novel stimuli. We quantified the P300 at a single electrode site and at region of interest (ROI) and examined the internal consistency reliability of the component, both via split-half reliability and as a function of trial number. Results indicated that the P300 to standard, deviant, and novel stimuli fell within moderate to high internal consistency reliability thresholds, and that scoring the component at an ROI led to slightly higher estimates of reliability. However, the percentage of data loss due to artifacts increased across the course of the task, suggesting that including more trials will not necessarily improve the reliability of the P300. Together, these results suggest that robust and reliable measurement of the P300 will require designing tasks that minimize trial number and maximize infant tolerability.

The virtual COVID-19 classroom: surveying outcomes, individual differences, and technology use in college students

The COVID-19 pandemic caused many colleges to quickly shift to virtual learning, leading students to rely on technology to complete coursework while also experiencing new situations and stressors. The present study explored students’ technology use in their online course in conjunction with several student outcomes and individual difference measures. Ninety-six undergraduate students were surveyed about devices used and their perceptions of those devices. In addition, the survey measured students’ engagement, motivation, procrastination, perceived stress, and self-efficacy. It also asked students to report their current grade as well as how satisfied and isolated they felt in their course. Relationships emerged in predictable ways between course outcomes and individual difference measures. And though laptops were most used for coursework, more smartphone use related to lower feelings of isolation. Lower feelings of isolation then related to higher grades and less stress. Regression analyses confirmed that smartphone use explained unique variance in feelings of isolation, and further revealed that perceived stress consistently predicted all outcomes. From these results and complementary qualitative survey data, it seems that both laptops and smartphones hold importance for academics in the current context. Educators should further explore the role of device in students’ experience as well as consider this information when designing online courses.

How many factors in factor analysis? New insights about parallel analysis with confidence intervals

Factor analysis is an extremely popular model for scale development prior to other modeling in much research in business and the social sciences. A central question in factor analysis remains the determination of the number of factors to extract and retain to explain as much of the data as possible, and do so parsimoniously. Parallel analysis can be helpful, but there is some confusion surrounding this technique, which may lead to incorrect conclusions. This research seeks first to clarify and correct these confusions. Second, we offer R, SAS, and SPSS programs to conduct parallel analysis in factor analysis. Third, we incorporate inferential statistics, enabling hypothesis testing and confidence intervals. Finally, we discuss how parallel analysis can help scholars in ongoing debates about individual differences scales, construct and measure dimensionality, and the utility of multi-item scales. Hopefully, the recurrent question, “How many factors?” can be answered more definitively.

Individual Differences in Structure Building: Impacts on Comprehension and Learning, Theoretical Underpinnings, and Support for Less Able Structure Builders

In this article, we highlight an underappreciated individual difference: structure building. Structure building is integral to many everyday activities and involves creating coherent mental representations of conversations, texts, pictorial stories, and other events. People vary in this ability in a way not generally captured by other better known concepts and individual difference measures. Individuals with lower structure-building ability consistently perform worse on a range of comprehension and learning measures than do individuals with higher structure-building ability, both in the laboratory and in the classroom. Problems include a range of comprehension processes, including encoding factual content, inhibiting irrelevant information, and constructing a cohesive situation model of a text or conversation. Despite these problems, recent research is encouraging in that techniques to improve the learning outcomes for low-ability structure builders have been identified. We argue that the accumulated research warrants the recognition of structure building as an important individual difference in cognitive functioning and that additional theoretical work is needed to understand the underpinnings of structure-building deficits.
