RESUMO

Open research practices seek to enhance the transparency and reproducibility of research. While there is evidence of increased uptake in these practices, such as study preregistration and open data, facilitated by new infrastructure and policies, little research has assessed general uptake of such practices across psychology university researchers. The current study estimates psychologists' level of engagement in open research practices across universities in the United Kingdom and Ireland, while also assessing possible explanatory factors that may impact their engagement. Data were collected from 602 psychology researchers in the United Kingdom and Ireland on the extent to which they have implemented various practices (e.g., use of preprints, preregistration, open data, open materials). Here we present the summarized descriptive results, as well as considering differences between various categories of researcher (e.g., career stage, subdiscipline, methodology), and examining the relationship between researcher's practices and their self-reported capability, opportunity, and motivation (COM-B) to engage in open research practices. Results show that while there is considerable variability in engagement of open research practices, differences across career stage and subdiscipline of psychology are small by comparison. We observed consistent differences according to respondent's research methodology and based on the presence of institutional support for open research. COM-B dimensions were collectively significant predictors of engagement in open research, with automatic motivation emerging as a consistently strong predictor. We discuss these findings, outline some of the challenges experienced in this study, and offer suggestions and recommendations for future research. Estimating the prevalence of responsible research practices is important to assess sustained behaviour change in research reform, tailor educational training initiatives, and to understand potential factors that might impact engagement.

RESUMO

Journal editors have a large amount of power to advance open science in their respective fields by incentivising and mandating open policies and practices at their journals. The Data PASS Journal Editors Discussion Interface (JEDI, an online community for social science journal editors: www.dpjedi.org ) has collated several resources on embedding open science in journal editing ( www.dpjedi.org/resources ). However, it can be overwhelming as an editor new to open science practices to know where to start. For this reason, we created a guide for journal editors on how to get started with open science. The guide outlines steps that editors can take to implement open policies and practices within their journal, and goes through the what, why, how, and worries of each policy and practice. This manuscript introduces and summarizes the guide (full guide: https://doi.org/10.31219/osf.io/hstcx ).

RESUMO

OBJECTIVE: The prevalence of research conducted online in the addiction field has increased rapidly over the past decade. However, little focus has been given to careless responding in these online studies, despite the issues it may cause for statistical inference and generalizability. Our aim was to examine whether alcohol use is associated with careless responses. METHOD: Raw data were requested from online studies examining alcohol use and related problems which also addressed careless responding. We obtained 13 data sets of 12,237 participants (Mage = 42.16, SD = 15.65, 50.5% female). The sample had an average Alcohol Use Disorders Identification Test (AUDIT) score of 10.88 (SD = 7.77). Predictors included demographic information (age, gender) and AUDIT total scores. The primary outcome was whether an individual was classed as a careless responder, for example, by failing an explicit attention check question. RESULTS: AUDIT total scores were associated with careless responding (OR = 1.07, 95% CI [1.06, 1.08], p < .001). Hazardous drinking or worse was associated with 2.21 greater odds (OR = 2.21, 95% CI [1.81, 2.71] of careless responding, whereas harmful drinking or worse was associated with 3.43 greater odds (OR = 3.43, 95% CI [2.83, 4.17]) and probable dependence was associated with 3.63 greater odds (OR = 3.63, 95% CI [2.95, 4.48]). CONCLUSIONS: Alcohol use and related problems are positively associated with careless responding in online research. Removal of individuals identified as careless responders may lead to issues of generalizability, and more care should be taken to identify and handle careless responder data.

RESUMO

OBJECTIVE: Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system, resulting in a range of potential motor and cognitive impairments. The latter can affect both executive functions that orchestrate general goal-directed behavior and social cognitive processes that support our ability to interact with others and maintain healthy interpersonal relationships. Despite a long history of research into the cognitive symptoms of MS, it remains uncertain if social cognitive disruptions occur independently of, or reflect underlying disturbances to, more foundational executive functions. The present preregistered study investigated this directly. METHOD: Employing an experimental design, we administered a battery of computerized tasks online to a large sample comprising 134 individuals with MS and 134 age- and sex-matched healthy controls (HCs). Three tasks measured elements of executive function (working memory, response inhibition, and switching) and two assessed components of social cognition disrupted most commonly in MS (emotion perception and theory of mind). RESULTS: Individuals with MS exhibited poorer working memory (d = .31), response inhibition (d = -.26), emotion perception (d = .32), and theory of mind (d = .35) compared with matched HCs. Furthermore, exploratory mediation analyses revealed that working memory performance accounted for approximately 20% of the group differences in both measures of social cognition. CONCLUSIONS: Disruptions to working memory appear to serve as one of the mechanisms underpinning disturbances to social cognition in MS. Future research should examine if the benefits of cognitive rehabilitation programs that incorporate working memory training transfer to these social cognitive processes.

RESUMO

Background: The race-based Implicit Association Test (IAT) was proposed to measure individual differences in implicit racial bias subsumed within social cognition. In recent years, researchers have debated the theoretical tenets underpinning the IAT, questioning whether performance on this task: (1) measures implicit attitudes that operate automatically outside of conscious awareness; (2) reflects individual differences in social cognition; and (3) can predict social behavior. One way to better address these research questions is to assess whether the race-IAT correlates with other implicit processes that are subsumed within social cognition. Aims: The current study assessed whether the race-IAT was related to other commonly used individual difference measures of implicit (and explicit) social cognition. Experiment 1 assessed whether dissociable patterns of performance on the race-IAT were related to measures of implicit imitative tendencies, emotion recognition and perspective taking toward White task actors, as well as explicit measures of trait and state affective empathy and racial bias. Overcoming limitations of task conceptual correspondence, Experiment 2 assessed whether these latter tasks were sensitive in detecting racial biases by using both White and Black task actors and again examined their relationships with the race-IAT. Method: In two lab-based experiments, 226 and 237 participants completed the race-IAT followed by an extensive battery of social cognition measures. Results: Across both experiments, pro-White/anti-Black bias on the race-IAT was positively related to a pro-White bias on explicit measures of positive affective empathy. However, relationships between the race-IAT and implicit imitative tendencies, perspective taking, emotion recognition, and explicit trait and negative state affective empathy were statistically equivalent. Conclusion: The race-IAT was consistently related to explicit measures of positive state affective empathy but not to other individual difference measures of implicit social cognition. These findings are discussed with regards to the theoretical underpinnings of the race-IAT as an individual difference measure of implicit social cognition, as well as alternative explanations relating to the reliability of social cognition measures and the various combinations of general-purpose (social and non-social) executive processes that underpin performance on these tasks.

RESUMO

PURPOSE: In March 2020, the U.K. government announced that people should isolate to reduce the spread of the virus that causes COVID-19. Outside a pandemic, psychosocial factors, such as socialization and mental health, may impact the relationship between hearing loss and increased dementia risk. We aim to report the impact of psychosocial factors, including social isolation, depression, and engagement in activities, on hearing and cognitive function in younger and older adults during the COVID-19 pandemic. METHOD: An online survey and experiment assessed self-reported psychosocial factors, self-reported hearing ability and speech-in-noise perception, and cognition. Data were collected between June 2020 and February 2021. Older (n = 112, Mage = 70.08) and younger (n = 121, Mage = 20.52) monolingual speakers of English, without any language or neurological disorders participated. Multiple linear regression models were employed to investigate hypothesized associations between psychosocial factors, and hearing and cognition, in older and younger adults. RESULTS: Multiple regression analyses indicated that older adults displayed poorer speech-in-noise perception and poorer performance on one of four cognitive tasks, compared with younger adults; increased depression was associated with poorer subjective hearing. Other psychosocial factors did not significantly predict hearing or cognitive function. CONCLUSIONS: Data suggest that self-reported hearing and depression are related. This conclusion is important for understanding the associations between hearing loss and cognitive decline in the long term, as both hearing loss and depression are risk factors for dementia.

RESUMO

OBJECTIVES: Problematic substance use is one of the most stigmatized health conditions leading research to examine how the labels and models used to describe it influence public stigma. Two recent studies examine whether beliefs in a disease model of addiction influence public stigma but result in equivocal findings-in line with the mixed-blessings model, Kelly et al. (2021) found that while the label "chronically relapsing brain disease" reduced blame attribution, it decreased prognostic optimism and increased perceived danger and need for continued care; however, Rundle et al. (2021) conclude absence of evidence. This study isolates the different factors used in these two studies to assess whether health condition (drug use vs. health concern), etiological label (brain disease vs. problem), and attributional judgment (low vs. high treatment stability) influence public stigma toward problematic substance use. METHOD: Overall, 1,613 participants were assigned randomly to one of the eight vignette conditions that manipulated these factors. They completed self-report measures of discrete and general public stigma and an indirect measure of discrimination. RESULTS: Greater social distance, danger, and public stigma but lower blame were ascribed to drug use relative to a health concern. Greater (genetic) blame was reported when drug use was labeled as a "chronically relapsing brain disease" relative to a "problem." Findings for attributional judgment were either inconclusive or statistically equivalent. DISCUSSION: The labels used to describe problematic substance use appear to impact discrete elements of stigma. We suggest that addiction is a functional attribution, which may explain the mixed literature on the impact of etiological labels on stigma to date.

RESUMO

In recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergraduate and postgraduate research training. Specifically, a critical overview of the literature which investigates how integrating open and reproducible science may influence student outcomes is needed. In this paper, we provide the first critical review of literature surrounding the integration of open and reproducible scholarship into teaching and learning and its associated outcomes in students. Our review highlighted how embedding open and reproducible scholarship appears to be associated with (i) students' scientific literacies (i.e. students' understanding of open research, consumption of science and the development of transferable skills); (ii) student engagement (i.e. motivation and engagement with learning, collaboration and engagement in open research) and (iii) students' attitudes towards science (i.e. trust in science and confidence in research findings). However, our review also identified a need for more robust and rigorous methods within pedagogical research, including more interventional and experimental evaluations of teaching practice. We discuss implications for teaching and learning scholarship.

RESUMO

OBJECTIVE: The degree awarding gap indicates that racially minoritised higher education students receive lower degree classifications relative to their white peers. While the reasons for this are complex, research suggests that educator and practitioner attitudes and behaviour towards racially minoritised students are a significant contributing factor. This preregistered study evaluates the effectiveness of unconscious racial bias training (URBT) to enhance National Health Service senior practitioner's recognition of how racial inequalities negatively impact racially minoritised students. DESIGN: A mixed-methods study with a pretest and post-test design was conducted in the higher education and healthcare practice environment. METHODS: Forty-nine NHS senior practitioners completed a 4-hour URBT workshop with activities focusing on activating stereotypes, exploring differences between unconscious and implicit bias, discussing the development of bias, and reflecting on student experiences of prejudice, harassment and discrimination. They completed pre- and post- quantitative measures that assessed the effectiveness of URBT and changes in racial competency, awareness and perceptions of unconscious racial bias. Qualitative measures explored the usefulness and perceived applications of URBT, and a 1-month follow-up assessed further how it had been applied within practice. RESULTS: Participants reported positive evaluations of URBT, higher perceived racial competency, awareness and perceptions of racial bias (ps<0.001, dz>0.35). After 1 month, key themes from qualitative responses suggested that participants had increased self-awareness and were exploring how to set up mentoring and working groups, change recruitment and progression processes, and diversify the taught curriculum. CONCLUSIONS: URBT may be one effective strategy to enhance awareness and encourage reflections of racial bias. We discuss how reducing racial inequalities requires a multifaceted approach that affords upfront conversations about systemic racism, implements effective initiatives, policies and procedures, and engages in continuous evaluation.

RESUMO

In the January 2022 issue of Perspectives, Götz et al. argued that small effects are "the indispensable foundation for a cumulative psychological science." They supported their argument by claiming that (a) psychology, like genetics, consists of complex phenomena explained by additive small effects; (b) psychological-research culture rewards large effects, which means small effects are being ignored; and (c) small effects become meaningful at scale and over time. We rebut these claims with three objections: First, the analogy between genetics and psychology is misleading; second, p values are the main currency for publication in psychology, meaning that any biases in the literature are (currently) caused by pressure to publish statistically significant results and not large effects; and third, claims regarding small effects as important and consequential must be supported by empirical evidence or, at least, a falsifiable line of reasoning. If accepted uncritically, we believe the arguments of Götz et al. could be used as a blanket justification for the importance of any and all "small" effects, thereby undermining best practices in effect-size interpretation. We end with guidance on evaluating effect sizes in relative, not absolute, terms.

RESUMO

To help move researchers away from heuristically dismissing "small" effects as unimportant, recent articles have revisited arguments to defend why seemingly small effect sizes in psychological science matter. One argument is based on the idea that an observed effect size may increase in impact when generalized to a new context because of processes of accumulation over time or application to large populations. However, the field is now in danger of heuristically accepting all effects as potentially important. We aim to encourage researchers to think thoroughly about the various mechanisms that may both amplify and counteract the importance of an observed effect size. Researchers should draw on the multiple amplifying and counteracting mechanisms that are likely to simultaneously apply to the effect when that effect is being generalized to a new and likely more dynamic context. In this way, researchers should aim to transparently provide verifiable lines of reasoning to justify their claims about an effect's importance or unimportance. This transparency can help move psychological science toward a more rigorous assessment of when psychological findings matter for the contexts that researchers want to generalize to.

RESUMO

AIMS: Substance use disorders (SUD) are associated with cognitive deficits that are not always addressed in current treatments, and this hampers recovery. Cognitive training and remediation interventions are well suited to fill the gap for managing cognitive deficits in SUD. We aimed to reach consensus on recommendations for developing and applying these interventions. DESIGN, SETTING AND PARTICIPANTS: We used a Delphi approach with two sequential phases: survey development and iterative surveying of experts. This was an on-line study. During survey development, we engaged a group of 15 experts from a working group of the International Society of Addiction Medicine (Steering Committee). During the surveying process, we engaged a larger pool of experts (n = 54) identified via recommendations from the Steering Committee and a systematic review. MEASUREMENTS: Survey with 67 items covering four key areas of intervention development: targets, intervention approaches, active ingredients and modes of delivery. FINDINGS: Across two iterative rounds (98% retention rate), the experts reached a consensus on 50 items including: (i) implicit biases, positive affect, arousal, executive functions and social processing as key targets of interventions; (ii) cognitive bias modification, contingency management, emotion regulation training and cognitive remediation as preferred approaches; (iii) practice, feedback, difficulty-titration, bias modification, goal-setting, strategy learning and meta-awareness as active ingredients; and (iv) both addiction treatment work-force and specialized neuropsychologists facilitating delivery, together with novel digital-based delivery modalities. CONCLUSIONS: Expert recommendations on cognitive training and remediation for substance use disorders highlight the relevance of targeting implicit biases, reward, emotion regulation and higher-order cognitive skills via well-validated intervention approaches qualified with mechanistic techniques and flexible delivery options.

RESUMO

AIM: This study explored the lived experiences of racial bias for Black, Asian and Minority Ethnic students undertaking an undergraduate or post-graduate degree in nursing, midwifery and allied health courses in the United Kingdom. BACKGROUND: Previous research indicates that students from Black, Asian and Minority Ethnic groups have fewer opportunities to succeed at university and this has brought about a race awarding gap in their degree attainment. The reasons for this awarding gap are complex and multi-factorial and it is crucial that the lived experiences of racial bias are explored from the student perspective. DESIGN: A hermeneutic phenomenological approach was adopted to elicit individual and collective experiences in the practice environment, a mandatory component of the student's degree. METHODS: A focus group and individual semi-structured interviews were conducted to collect data from sixteen participants and analysed using thematic analysis RESULTS: Three encompassing themes were identified which included a sense of not belonging, trauma impact on mental health and understanding covert and overt racism. Participants reported incidences of racism and appeared to be traumatised by their experiences within practice and the university. They also reported poor mental health and well-being as shared experiences and a lack of confidence in the university and practice to mitigate racial issues. CONCLUSIONS: Meaningful action must be taken by universities and practice partners to advance racial inequality initiatives by having robust anti-racism action plans and processes. These should be co-created with students and staff to reduce the race awarding gap.

RESUMO

Studies have produced vastly disparate findings when exploring relationships between social networking site (SNS) usage and psychosocial well-being. These inconsistencies might reflect a lack of consideration for how people use SNS; specifically, while meaningful interactions are suggested to foster positive feelings, the passive consumption of others' feeds is proposed to have negative effects on users' well-being. To facilitate the empirical evaluation of these claims, the present study developed a computerised task to measure styles of usage on a mock SNS platform. Administering this Social Network Site Behaviour Task (SNSBT) online to 526 individuals, we identified three dissociable usage styles that extend the active-passive dichotomy employed frequently in the literature: passive use (consuming content posted by others), reactive use (reacting to others' content), and interactive use (interacting with others through content sharing). Furthermore, our data reveal that these usage styles differ on several measures of psychosocial variables employed frequently in the disparate literature: more interactive users reported greater feelings of social connectedness and social capital than passive or reactive users. Importantly, however, our results also reveal the multi-dimensional nature of usage styles, with online network size and time spent on SNS platforms serving as potentially confounding influences on some psychosocial measures. These findings not only advance our understanding of SNS behaviour by providing empirical support for theoretic propositions, but also demonstrate the utility of the SNSBT for experimental investigations into the psychosocial outcomes of different SNS usage styles.

RESUMO

OBJECTIVE: Public health policies aim to reduce alcohol consumption and related harms by controlling the cost and availability of alcohol, yet industry actors seek to position branded beverages appealingly vis-à-vis other products. To inform the development of regulatory strategies, it is important to understand how alcohol branding interacts with seductive pricing strategies to influence purchasing decisions. Toward this aim, the current study examines how the "decoy effect" may operate to modify purchasing decisions for branded alcoholic beverages. METHOD: Social drinkers (n = 98, 66.6% female; M AUDIT = 5.00, SD = 4.42) completed an online Decoy Assessment, choosing from a range of (non)branded, (non)alcoholic beverage offers based on price and quantity. These initial purchasing decisions were then re-assessed when a decoy product--offering a quantity in between the two original offers but at a significantly higher price--was introduced into the choice array. RESULTS: The decoy modified initial purchasing decisions for alcoholic compared with nonalcoholic beverages, and this effect was exacerbated by alcohol branding. Increases in self-reported alcohol consumption were associated with a greater change from choices for branded alcoholic beverages. CONCLUSIONS: When faced with a choice conflict, individuals who consume alcohol may be nudged into selecting more expensive branded alcoholic beverages. These findings may inform the development of alcohol control policies relating to branding and relative pricing/product placement.

RESUMO

Research in perception and attention has typically sought to evaluate cognitive mechanisms according to the average response to a manipulation. Recently, there has been a shift toward appreciating the value of individual differences and the insight gained by exploring the impacts of between-participant variation on human cognition. However, a recent study suggests that many robust, well-established cognitive control tasks suffer from surprisingly low levels of test-retest reliability (Hedge, Powell, & Sumner, 2018b). We tested a large sample of undergraduate students (n = 160) in two sessions (separated by 1-3 weeks) on four commonly used tasks in vision science. We implemented measures that spanned a range of perceptual and attentional processes, including motion coherence (MoCo), useful field of view (UFOV), multiple-object tracking (MOT), and visual working memory (VWM). Intraclass correlations ranged from good to poor, suggesting that some task measures are more suitable for assessing individual differences than others. VWM capacity (intraclass correlation coefficient [ICC] = 0.77), MoCo threshold (ICC = 0.60), UFOV middle accuracy (ICC = 0.60), and UFOV outer accuracy (ICC = 0.74) showed good-to-excellent reliability. Other measures, namely the maximum number of items tracked in MOT (ICC = 0.41) and UFOV number accuracy (ICC = 0.48), showed moderate reliability; the MOT threshold (ICC = 0.36) and UFOV inner accuracy (ICC = 0.30) showed poor reliability. In this paper, we present these results alongside a summary of reliabilities estimated previously for other vision science tasks. We then offer useful recommendations for evaluating test-retest reliability when considering a task for use in evaluating individual differences.

RESUMO

BACKGROUND/OBJECTIVES: Cross-sectional research has demonstrated weight-related stigma and discrimination, however experimental research providing causal evidence of financial-based weight discrimination is lacking. The aim of these preregistered experiments was to examine whether a novel paradigm in which participants attributed financial rewards and punishments could be used to detect weight bias. SUBJECTS/METHODS: One-hundred and twenty-one individuals participated in experiment 1 and one-hundred and sixty-six individuals participated in experiment 2. Both studies were conducted online, and participants were provided with biographies of hypothetical individuals in which weight-status was manipulated (normal weight vs. overweight/obesity) before being asked to provide rewards and punishments on their cognitive performance. In experiment 1 (within-participants design) participants observed one individual they believed to be normal weight and one individual they believed to be overweight/have obesity. In experiment 2 (between-participants design) participants observed one individual whilst also being provided with information about food addiction (Food addiction is real + individual with overweight/obesity vs. food addiction is a myth + individual with overweight/obesity vs control + individual with normal weight). RESULTS: In experiment 1, participants punished individuals who were described as having overweight/obesity to a greater extent to individuals who were normal weight (Hedge's g = -0.21 [95% CI: -0.02 to -0.41], p = 0.026), but there was no effect on rewards. They were also less likely to recommend individuals with overweight/obesity to pass the tasks (X2(1) = 10.05, p = 0.002). In experiment 2, participants rewarded individuals whom they believed were overweight/obese to a lesser extent than normal-weight individuals (g = 0.49 [95% CI: 0.16 to 0.83]. There was no effect on punishment, nor any impact of information regarding food addiction as real vs a myth. CONCLUSION: Using a novel discrimination task, these two experiments demonstrate causal evidence of weight-based discrimination in financial decision making.

RESUMO

Crowdsourcing-the process of using the internet to outsource research participation to "workers"-has considerable benefits, enabling research to be conducted quickly, efficiently, and responsively, diversifying participant recruitment, and allowing access to hard-to-reach samples. One of the biggest threats to this method of online data collection however is the prevalence of careless responders who can significantly affect data quality. The aims of this preregistered systematic review and meta-analysis were: (a) to examine the prevalence of screening for careless responding in crowdsourced alcohol-related studies; (b) to examine the pooled prevalence of careless responding; and (c) to identify any potential moderators of careless responding across studies. Our review identified 96 eligible studies (∼126,130 participants), of which 51 utilized at least one measure of careless responding, 53.2%, 95% CI [42.7%-63.3%]; ∼75,334 participants. Of these, 48 reported the number of participants identified by careless responding method(s) and the pooled prevalence rate was ∼11.7%, 95% CI [7.6%-16.5%]. Studies using the MTurk platform identified more careless responders compared to other platforms, and the number of careless response items was positively associated with prevalence rates. The most common measure of careless responding was an attention check question, followed by implausible response times. We suggest that researchers plan for such attrition when crowdsourcing participants and provide practical recommendations for handling and reporting careless responding in alcohol research.

RESUMO

Many disciplines are facing a "reproducibility crisis", which has precipitated much discussion about how to improve research integrity, reproducibility, and transparency. A unified effort across all sectors, levels, and stages of the research ecosystem is needed to coordinate goals and reforms that focus on open and transparent research practices. Promoting a more positive incentive culture for all ecosystem members is also paramount. In this commentary, we-the Local Network Leads of the UK Reproducibility Network-outline our response to the UK House of Commons Science and Technology Committee's inquiry on research integrity and reproducibility. We argue that coordinated change is needed to create (1) a positive research culture, (2) a unified stance on improving research quality, (3) common foundations for open and transparent research practice, and (4) the routinisation of this practice. For each of these areas, we outline the roles that individuals, institutions, funders, publishers, and Government can play in shaping the research ecosystem. Working together, these constituent members must also partner with sectoral and coordinating organisations to produce effective and long-lasting reforms that are fit-for-purpose and future-proof. These efforts will strengthen research quality and create research capable of generating far-reaching applications with a sustained impact on society.
