Predicting implicit attitudes with natural language data.

Large-scale language datasets and advances in natural language processing offer opportunities for studying people's cognitions and behaviors. We show how representations derived from language can be combined with laboratory-based word norms to predict implicit attitudes for diverse concepts. Our approach achieves substantially higher correlations than existing methods. We also show that our approach is more predictive of implicit attitudes than are explicit attitudes, and that it captures variance in implicit attitudes that is largely unexplained by explicit attitudes. Overall, our results shed light on how implicit attitudes can be measured by combining standard psychological data with large-scale language data. In doing so, we pave the way for highly accurate computational modeling of what people think and feel about the world around them.

The contributions of positive outgroup and negative ingroup evaluation to implicit bias favoring outgroups.

People sometimes prefer groups to which they do not belong (outgroups) over their own groups (ingroups). Many long-standing theoretical perspectives assume that this outgroup favorability bias primarily reflects negative ingroup evaluations rather than positive outgroup evaluations. To examine the contributions of negative ingroup versus positive outgroup evaluations to outgroup bias, we examined participants' data (total n > 879,000) from Implicit Association Tests [A. G. Greenwald, D. E. McGhee, J. L. K. Schwartz, J. Pers. Soc. Psychol. 74, 1464-1480 (1998)] measuring intergroup attitudes across four social domains in exploratory and preregistered confirmatory analyses. Process modeling [F. R. Conrey, J. W. Sherman, B. Gawronski, K. Hugenberg, C. J. Groom, J. Pers. Soc. Psychol. 89, 469-487 (2005)] was applied to the responses of participants who demonstrated implicit outgroup bias to separately estimate the contributions of negative ingroup and positive outgroup evaluations. The outgroup biases of lower-status group members (i.e., Asian, Black, gay and lesbian, and older people) consistently reflected greater contributions of positive outgroup evaluations than negative ingroup evaluations. In contrast, the outgroup biases of higher-status group members (i.e., White, straight, and younger people) reflected a more varied pattern of evaluations. We replicated this pattern of results using explicitly measured intergroup evaluations. Taking these data together, the present research demonstrates a positive-negative asymmetry effect of outgroup bias, primarily among members of lower-status groups.

Using reaction time procedures to assess implicit attitudes toward violence in a nonconvicted male sample.

In this study, we sought to capture implicit attitudes toward violence by administering response latency measures. We then examined their associations with explicit (e.g., assessed with self-report) attitudes toward violence and self-reported violent behavior in a combined sample of males from a Canadian university and males from the general community (N = 251; 156 students and 95 community members). To date, there have been mixed findings regarding these associations; some of this inconsistency may be due to the difficulty in accurately conceptualizing and assessing implicit attitudes toward violence. Therefore, we administered three response latency measures to assess this construct: a violence evaluation implicit association test (VE-IAT), a personalized VE-IAT (P-VE-IAT), and a violence evaluation relational responding task, along with three self-report measures of explicit attitudes toward violence and three self-report measures of violent behavior. More positive implicit attitudes toward violence were related to more positive explicit attitudes toward violence (for VE-IAT and P-VE-IAT; r = 0.18 to 0.22), greater likelihood of violence (for VE-IAT; r = 0.18 and for P-VE-IAT; r = 0.16), and greater propensity for violence (for the VE-IAT; r = 0.16). All measures of explicit attitudes toward violence and violent behavior were moderately to strongly associated with one another (r = 0.42 to 0.81). Furthermore, implicit attitudes toward violence explained additional variance in some violent outcomes above explicit attitudes alone. Our findings suggest that scores on certain reaction time measures are important for understanding likelihood and propensity for violence, especially when combined with explicit attitude measures.

Perceptions of older and younger adults who wear hearing aids.

OBJECTIVE: To investigate older and younger adults' perceptions of older and younger adults who wear hearing aids. DESIGN: Participants completed two Implicit Association Tests: One with images of older adults (OA-IAT) and one with images of younger adults (YA-IAT), either wearing or not wearing hearing aids. Participants also rated age, attractiveness, and intelligence of younger and older adults pictured with or without a hearing aid. STUDY SAMPLE: Thirty older adults (M age = 70 years, SD = 4.38) and 30 younger adults (M age = 23 years, SD = 3.01) who reported not having hearing aids or a diagnosed hearing impairment. RESULTS: For both IATs, older and younger participants responded faster and more accurately when images of individuals wearing hearing aids were paired with negative words in comparison to positive words. Photo ratings did not vary in relation to the presence or absence of hearing aids for either age group. CONCLUSION: Although the photo rating tasks indicate neutral explicit attitudes towards individuals who wear hearing aids, our interpretation of the IAT results indicates that younger and older adults may hold negative implicit attitudes towards both older and younger hearing aid users.

Improving the reliability and validity of the IAT with a dynamic model driven by similarity.

The Implicit Association Test (IAT), like many behavioral measures, seeks to quantify meaningful individual differences in cognitive processes that are difficult to assess with approaches like self-reports. However, much like other behavioral measures, many IATs appear to show low test-retest reliability and typical scoring methods fail to quantify all of the decision-making processes that generate the overt task performance. Here, we develop a new modeling approach for IATs based on the geometric similarity representation (GSR) model. This model leverages both response times and accuracy on IATs to make inferences about representational similarity between the stimuli and categories. The model disentangles processes related to response caution, stimulus encoding, similarities between concepts and categories, and response processes unrelated to the choice itself. This approach to analyzing IAT data illustrates that the unreliability in IATs is almost entirely attributable to the methods used to analyze data from the task: GSR model parameters show test-retest reliability around .80-.90, on par with reliable self-report measures. Furthermore, we demonstrate how model parameters result in greater validity compared to the IAT D-score, Quad model, and simple diffusion model contrasts, predicting outcomes related to intergroup contact and motivation. Finally, we present a simple point-and-click software tool for fitting the model, which uses a pre-trained neural network to estimate best-fit parameters of the GSR model. This approach allows easy and instantaneous fitting of IAT data with minimal demands on coding or technical expertise on the part of the user, making the new model accessible and effective.

Explicit and implicit attitudes of occupational therapy workshops' staff towards people with intellectual disabilities.

The aim of this article is to present explicit and implicit attitudes of occupational therapy (OT) staff towards people with intellectual disabilities. The study was conducted on a group of 77 OT employees. To explore the explicit attitude, the Conditional Respect for Persons with Disabilities Questionnaire (Kurtek, Roczniki Psychologiczne, 2018, 4, 327-344) was used, while to estimate the implicit attitude, the Intellectual Disability Attitudes Implicit Association Test was applied (Kurtek, Roczniki Psychologiczne, 2021, 1, 43-64). At the explicit level, OT staff tended to tolerate negative and overrate positive behaviours of people with intellectual disabilities, which indicates a tendency to favour the individuals. However, the opposite devalorizing tendency was observed at the implicit dimension, which indicates aversive ableism. Although the study confirmed the independence of the two dimensions of the personnel's attitude, relationships were observed between the disclosure of negativity towards antagonistic behaviours of the people with intellectual disabilities and a decrease in the level of their implicit devaluation.

The Effect of Alcohol and Sexual Arousal on Explicit and Implicit Condom Attitudes and Intentions to Use a Condom.

Alcohol and sexual arousal are contextual determinants of condomless sex. Dual-process theory postulates that two types of cognitive processing contribute to the regulation of behavior: one that is fast, intuitive and automatic, and another that is slower and deliberative. This study applied a dual-process model to investigate condomless sexual behavior, highlighting the potential importance of implicit attitudes in condomless sex. We investigated whether the impact of alcohol and sexual arousal on condom use-related attitudes and intentions was explained by diminished working memory capacity, as dual-process models suggest. We also investigated whether this effect could be explained by implicit and explicit attitudes toward condom use. Male participants (N = 30) were randomized using a 2 × 2 within-subjects design that manipulated alcohol intoxication (placebo vs. alcohol beverages) and sexual arousal (neutral vs. erotic movie clips). We measured participants' working memory capacity, intentions to use a condom, and explicit and implicit attitudes toward condom use. Significant main effects of alcohol intoxication and sexual arousal on working memory capacity were found. No significant interaction was found for the combined effect of alcohol intoxication and sexual arousal on intentions to use a condom. There was no significant effect of implicit attitudes on intentions to use a condom, although a trend toward significance (p = 0.06) was found for the effect of implicit attitudes on intentions to use a condom when participants were in a state of alcohol intoxication. Theoretical and practical implications of this study are discussed.

Social Movements as Parsimonious Explanations for Implicit and Explicit Attitude Change.

Recently, interest in aggregate and population-level implicit and explicit attitudes has opened inquiry into how attitudes relate to sociopolitical phenomenon. This creates an opportunity to examine social movements as dynamic forces with the potential to generate widespread, lasting attitude change. Although collective action remains underexplored as a means of reducing bias, we advance historical and theoretical justifications for doing so. We review recent studies of aggregate attitudes through the lens of social movement theory, proposing movements as a parsimonious explanation for observed patterns. We outline a model for conceptualizing causal pathways between social movements and implicit and explicit attitudes among participants, supporters, bystanders, and opponents. We identify six categories of mechanisms through which movements may transform attitudes: changing society; media representations; intergroup contact and affiliation; empathy, perspective-taking, and reduced intergroup anxiety; social recategorization; and social identification and self-efficacy processes. Generative questions, testable hypotheses, and promising methods for future work are discussed.

Enjoy exercise more: The effects of dual-channel evaluative conditioning on implicit attitudes toward exercise.

Researchers have been looking for effective interventions to promote physical activity due to its great impact on both physical and mental health. In two studies, the current research investigated (1) whether evaluative conditioning could increase implicit attitudes toward exercise; (2) whether dual-channel evaluative conditioning had a greater influence compared to single-channel evaluative conditioning. In Study 1, results from 32 participants (7 males, 25 females; Mage = 19.470, SDage = 1.174) were used to compare the audiovisual dual-channel with the visual single-channel evaluative conditioning. In Study 2, we analyzed data from 100 participants (35 males, 65 females; Mage = 20.990, SDage = 3.141) and compared the visual-kinesthetic dual-channel with the visual single-channel evaluative conditioning. The results showed that individuals' implicit attitudes toward exercise were more positively affected by dual-channel than single-channel evaluative conditioning.

The project implicit international dataset: Measuring implicit and explicit social group attitudes and stereotypes across 34 countries (2009-2019).

For decades, researchers across the social sciences have sought to document and explain the worldwide variation in social group attitudes (evaluative representations, e.g., young-good/old-bad) and stereotypes (attribute representations, e.g., male-science/female-arts). Indeed, uncovering such country-level variation can provide key insights into questions ranging from how attitudes and stereotypes are clustered across places to why places vary in attitudes and stereotypes (including ecological and social correlates). Here, we introduce the Project Implicit:International (PI:International) dataset that has the potential to propel such research by offering the first cross-country dataset of both implicit (indirectly measured) and explicit (directly measured) attitudes and stereotypes across multiple topics and years. PI:International comprises 2.3 million tests for seven topics (race, sexual orientation, age, body weight, nationality, and skin-tone attitudes, as well as men/women-science/arts stereotypes) using both indirect (Implicit Association Test; IAT) and direct (self-report) measures collected continuously from 2009 to 2019 from 34 countries in each country's native language(s). We show that the IAT data from PI:International have adequate internal consistency (split-half reliability), convergent validity (implicit-explicit correlations), and known groups validity. Given such reliability and validity, we summarize basic descriptive statistics on the overall strength and variability of implicit and explicit attitudes and stereotypes around the world. The PI:International dataset, including both summary data and trial-level data from the IAT, is provided openly to facilitate wide access and novel discoveries on the global nature of implicit and explicit attitudes and stereotypes.

Assessing sleep-related attitudes with the implicit association test: A prospective study in young adults.

The measurement of automatic attitudes towards sleep, in addition to reflective self-reports, might improve our ability to predict and explain sleep-hindering practices. Two types of implicit association tests (IATs), a sleep-related evaluations IAT and a sleep-related self-identity IAT, were developed to evaluate their efficacy for assessing automatic sleep-related attitudes. In addition, a speeded self-report measure of sleep evaluations was explored as a means to assess automatic sleep-related attitudes. The study included 136 young adults (age = 21.70 ± 2.22, 43% female). At baseline, the two IATs, the speeded self-report, and standard self-reports of sleep determinants (reflective attitudes, self-efficacy, intention and action planning for sleep-promoting behaviour), sleep hygiene practices, sleep quality, and sleep duration were assessed. All variables except for the sleep determinants were assessed again at 2-week follow-up. The results demonstrated good reliability of the two IAT versions, but both IATs were unrelated to the speeded self-report, the sleep determinants, sleep practices, sleep quality or sleep duration. The speeded self-report correlated significantly with the standard self-reports of sleep determinants. Baseline scores on the IATs or speeded self-report did not predict sleep hygiene practices, sleep duration or sleep quality at follow-up. The findings indicate that sleep-related IATs might not be suited to assess automatic sleep-related attitudes. Further investigation is needed to determine whether speeded self-reports are valid measures of automatic attitudes. Moreover, more empirical research is required to clarify the role of automatic processes for sleep hygiene behaviours.

Reciprocal associations between implicit attitudes and drinking in emerging adulthood.

BACKGROUND: Implicit alcohol attitudes are considered important in the etiology of drinking, and theory posits reciprocal associations between them. Research testing reciprocal associations between implicit attitudes (using the Implicit Association Task, IAT) and drinking is limited by a failure to consider multiple processes influencing performance on the IAT and to disaggregate within- and between-person effects. The current study addressed these limitations by using a diffusion model to analyze IAT data and Latent Curve Models with Structured Residuals to test reciprocal associations. METHODS: The sample included 314 emerging adults from the community (52% female; predominantly non-Hispanic Caucasian (76%) or African American (15%)) assessed annually for three years. Differences between IAT conditions in the drift rate parameter of the EZ-diffusion model (vΔ) were used as an alternative to traditional response-time-based indices from the IAT (d-scores). Differences in drift rate have been found to index implicit attitudes effectively. RESULTS: Within-person reciprocal associations were supported, but between-person associations were not. Positive implicit alcohol attitudes (vΔ) were prospectively associated with heavy drinking, which was positively associated with subsequent positive implicit alcohol attitudes. CONCLUSIONS: We found that positive implicit alcohol attitudes and heavy drinking reinforce each other in a negative cascade within individuals. The results highlight the importance of disaggregating within- and between-person prospective effects when testing dual process models and suggest that the diffusion model may be a fruitful approach to enhance the construct validity of IAT assessed implicit attitudes.

Assessment of medical student burnout: toward an implicit measure to address current issues.

The feasibility of implicitly assessing medical student burnout was explored, using the Implicit Relational Assessment Procedure (IRAP), to measure longitudinal student burnout over the first two years of medical school and directly comparing it with an existing explicit measure of burnout (Maslach Burnout Inventory; MBI). Three successive cohorts of medical students completed both implicit and explicit measures of burnout at several time points during their first two years of medical school. Both assessments were conducted via the internet within a one-week period during the first week of medical school, the end of the first year of medical school, and the end of the second year, though not all cohorts were able to complete the assessments at all time points. Mixed linear models were used to compare the two measures directly, as well as to evaluate changes over time in each measure separately. Minimal correspondence was observed between the implicit and explicit measures of burnout on a within-subject basis. However, when analyzed separately, all subscales of both measures detected significant change over time in the direction of greater levels of burnout, particularly during the first year of medical school. These results provide preliminary evidence the IRAP is able to assess implicit attitudes related to burnout among medical students, though additional research is needed. The IRAP detected consistent improvements in positive implicit attitudes toward medical training during students' second year of medical school, which was not detected by the MBI. Possible implications of these findings are discussed.

Evidence That Habit Moderates the Implicit Belief-Behavior Relationship in Health Behaviors.

BACKGROUND: Theory suggests that implicit beliefs are more likely to be associated with spontaneous, impulsive health behaviors (e.g., smoking, snacking), while controlled, consciously accessible beliefs are more likely to be associated with behaviors that require deliberation and reasoned decision-making (e.g., physical activity, healthy food selection). Consistent with these predictions, we proposed that as behaviors become habitual, they require less deliberation to enact and are thus more likely to be controlled by non-conscious processes, as indicated by stronger associations with implicit beliefs. The present study tested the moderating effect of habit on the effects of implicit beliefs on two health behaviors. METHOD: Two samples of university students completed measures of attitude, habit, and implicit beliefs for free-sugar intake (sample 1) and heavy episodic drinking (sample 2) at an initial time point, with follow-up behavioral measures taken at 2 and 4 weeks later, respectively. RESULTS: Path analyses indicated that attitude and habit predicted behavior in both samples, and habit moderated the implicit belief-behavior relationship in both samples. The effect of implicit beliefs on behavior was larger among participants reporting strong habits. Implicit beliefs did not moderate the effect of explicit attitudes on behavior. CONCLUSION: Findings provide preliminary evidence that experiencing health behaviors as habitual is associated with a stronger implicit beliefs-health behavior relationship.

Interindividual differences in energy intake after sleep restriction: The role of personality and implicit attitudes toward food.

Sleep restriction (SR) often leads to an increase in energy intake (EI). However, large variability in EI after SR is often observed, which suggests that individual characteristics may affect food intake. The objective of this study was to explore the influence of characteristics generally associated with risk-taking (sensitivity to reward and personality traits: impulsiveness, sensation seeking) and implicit attitudes toward food on EI after sleep loss. 17 subjects completed the NEO-PI-3, an Implicit Association Test measuring implicit attitudes towards healthy and unhealthy foods, and the Sensitivity to Punishment and Sensitivity to Reward Questionnaire. 24h Ad libitum EI was assessed following a habitual sleep night, a 50% SR with an advanced wake time, and a 50% SR with a delayed bedtime. Changes in EI between each SR condition and the control condition (ΔEI) were calculated for each subject. Despite no changes in overall EI between sleep conditions, results showed large interindividual variations (-669 to +899 kcal) across SR conditions. Regression modeling showed that a lower sensation seeking and higher favorable implicit attitudes towards unhealthy food were significantly associated with increased ΔEI in the advanced wake time condition. For the delayed bedtime, lower sensation seeking was associated with increased ΔEI while controlling for age, sex, REM sleep, and implicit attitudes. These results suggest that certain personality traits and implicit attitudes toward food are associated with changes in EI after sleep loss.

Development of children's implicit and explicit attitudes toward healthy food: Personal and environmental factors.

This cross-sectional study investigates the implicit and explicit food attitudes of 1,412 Croatian children (5-9 years old) and extends our knowledge regarding how those attitudes relate to food behavior, while accounting for the potential influence of age and environmental variables such as watching television and poverty. While our findings corroborate previous work to show that children's explicit attitudes tend to be more positive toward unhealthy than healthy foods, we also find that implicit attitudes are actually more positive toward healthy than unhealthy foods. Both implicit and explicit attitudes toward healthy foods were more positive at older ages. More positive attitudes were associated with (a) a stronger belief that healthy foods "make me strong" and (b) greater consumption of healthy foods. Watching television was associated with more favorable attitudes toward unhealthy foods. Our study demonstrates how accounting for both implicit and explicit attitudes across different age groups aids understanding of children's food-related beliefs and behaviors. These insights can help health policy makers and parents instill positive attitudes toward healthy food among children early on and increase their consumption of healthy foods during childhood.

A cross-lagged model of habits, implicit attitudes, autonomous motivation, and physical activity during COVID-19.

Although the relationship between autonomous motivation and impulsive processes has been acknowledged in the context of physical activity, the directionality of this relationship is not clearly understood. The COVID-19 pandemic provides a unique opportunity to investigate such relationships due to the fact that contextual changes brought about by government restrictions (e.g., stay at home orders, indoor gymnasium closures) may have influenced people's physical activity habits and motivation. The purpose of this study was to therefore investigate the bi-directional relationships between physical activity and previously established correlates: autonomous motivation, implicit attitudes, and habit. A sample of university students completed measures that assessed autonomous motivation, implicit attitude, habit and behaviors towards meeting physical activity guidelines each week during the coronavirus period at two time points, two weeks apart in a cross-lagged panel design. Path analysis found a significant reciprocal relationship between habits and autonomous motivation. There were no significant reciprocal relationships between autonomous motivation and implicit attitude, or with any study constructs and behavior. Current findings provide important preliminary formative evidence of associations between autonomous motivation and impulsive behavioral correlates, indicating a bi-directional relationship between autonomous motivation and physical activity habits.

The best game in town: The reemergence of the language-of-thought hypothesis across the cognitive sciences.

Mental representations remain the central posits of psychology after many decades of scrutiny. However, there is no consensus about the representational format(s) of biological cognition. This paper provides a survey of evidence from computational cognitive psychology, perceptual psychology, developmental psychology, comparative psychology, and social psychology, and concludes that one type of format that routinely crops up is the language-of-thought (LoT). We outline six core properties of LoTs: (i) discrete constituents; (ii) role-filler independence; (iii) predicate-argument structure; (iv) logical operators; (v) inferential promiscuity; and (vi) abstract content. These properties cluster together throughout cognitive science. Bayesian computational modeling, compositional features of object perception, complex infant and animal reasoning, and automatic, intuitive cognition in adults all implicate LoT-like structures. Instead of regarding LoT as a relic of the previous century, researchers in cognitive science and philosophy-of-mind must take seriously the explanatory breadth of LoT-based architectures. We grant that the mind may harbor many formats and architectures, including iconic and associative structures as well as deep-neural-network-like architectures. However, as computational/representational approaches to the mind continue to advance, classical compositional symbolic structures - that is, LoTs - only prove more flexible and well-supported over time.

Police as threat: The influence of race and the summer of Black Lives Matter on implicit and explicit attitudes towards the police.

Police officers partially rely on implicit and explicit stereotypes in their interactions with the public. We investigated if these attitudes are reciprocated, specifically, if people of color implicitly fear police, and whether the events of the summer of 2020 changed the public's attitudes about police. Seven hundred and fifty-nine college students (235 BIPOC) participated, 373 in 2019, 386 in fall 2020. BIPOC participants more readily implicitly associated police officers with threat; implicit police-as-threat scores increased after the summer of 2020 regardless of race. Explicit attitudes showed the same pattern: BIPOC participants had less favorable attitudes of police; participants in Fall 2020 had less favorable attitudes of police. Implicit attitudes were predicted by race, time, the experience of being treated with (dis)respect, and an emphasis on the binding aspect of morality. Explicit attitudes were predicted by the same variables, as well as specific community variables, the moral foundation of individualizing, and implicit attitudes.

Effects of pairing health warning labels with energy-dense snack foods on food choice and attitudes: Online experimental study.

BACKGROUND: There is limited evidence concerning the potential effectiveness of health warning labels (HWLs) using images and text to depict possible negative health consequences of consumption, for reducing selection of energy-dense snack foods. Furthermore, the underlying mechanisms have received little attention; particularly effects on implicit attitudes, which previous work has shown may mediate the effect of aversive images on food choice. AIM: To assess the impact of pairing image- and text-based HWLs with energy-dense snack foods on a) the selection of, and b) implicit and explicit attitudes towards, those foods. METHODS: Online experimental study with a representative UK sample (n = 1185), using a 2(Image/No Image) x 2(Text/No Text) factorial between-subjects design. Participants were randomised to one of four study arms, viewing snack food images paired with either: image-only HWLs, text-only HWLs, image-and-text HWLs, or no HWLs (control). HWLs concerned various negative health consequences of excess energy intake, such as heart disease and type 2 diabetes. The primary outcome was hypothetical food choice (energy-dense snack foods versus fruit), assessed post-intervention. Secondary outcomes were implicit and explicit attitudes. RESULTS: Neither food choice nor explicit attitudes were changed significantly by any type of HWL. Implicit attitudes towards energy-dense snack foods were more negative after exposure to text-only or image-and-text HWLs. Both implicit and explicit attitudes predicted unique variance in food choice. CONCLUSIONS: This study suggests that short-term repeated exposure to HWLs paired with energy-dense snack foods may not consistently alter food choices, but can change implicit attitudes associated with food choices. Further laboratory and field studies are needed to more definitively assess the impact of HWLs on food selection and consumption in applied contexts and over time, as well as delineate underlying mechanisms.
