Practice in visual search produces decreased capacity demands but increased distraction

Lavie (1995) proposed a load account of selective attention, which holds that spare capacity is involuntarily allocated to the processing of irrelevant stimuli. In support of this account, Lavie and Cox (1997) combined a letter search task with a flanker task and found that increasing load (search set size) resulted in decreased interference from an irrelevant distractor letter. In three experiments using a very similar procedure, we varied distractor location and distractor distinctiveness and observed that as load increased (from set size 2 to set size 6), there was a consistent reduction in interference. Critically, we addressed a fundamental hypothesis derived from the load account-that practice reduces capacity demands. This hypothesis leads to the rather counterintuitive prediction that as performance improves with practice, distractor processing should actually increase. Indeed, we found that interference in a high-load condition (set size 6), but not in a low-load condition (set size 2), did increase with practice. We describe a two-stage dilution account of attention that accommodates these results.     

Turning the process-dissociation procedure inside-out: A new technique for understanding the relation between conscious and unconscious influences

While there is now general agreement that memory gives rise to both conscious and unconscious influences, there remains disagreement concerning the process architecture underlying these distinct influences. Do they arise from independent underlying systems (e.g., Jacoby, 1991) or from systems that are interactive (e.g., Joordens & Merikle, 1993)? In the current paper we present a novel “inside-out” technique that can be used with the process-dissociation paradigm to arrive at more concrete conclusions concerning this central question and demonstrate this technique via a meta-analysis of currently published findings. Our results suggest that the data presented in these studies vary in ways most consistent with the assumption that conscious and unconscious influences behave independently.     

Actor–partner interdependence of humility and relationship quality among couples transitioning to parenthood

The transition to parenthood is a challenging experience that often strains relationships, but perceiving one’s partner as humble (actor relational humility) and being perceived by one’s partner as humble (partner relational humility) were hypothesized to benefit couples during this transition. Married couples (N = 69) were tracked from the third trimester of pregnancy through 21 months postpartum. Husbands and wives provided ratings of relational humility and dyadic adjustment. Actor–partner interdependence models tested actor and partner effects of relational humility on dyadic adjustment across the transition. Although couples declined in dyadic adjustment over the transition at the same rate regardless of relational humility (counter to Hypothesis 2), those higher in relational humility reported greater dyadic adjustment at each time point during the transition (consistent with Hypothesis 1). These findings support the benefits of relational humility to relationship quality, and we call for further research into humility’s benefits during times of relationship transition.     

A common source of attention for auditory and visual tracking

Tasks that require tracking visual information reveal the severe limitations of our capacity to attend to multiple objects that vary in time and space. Although these limitations have been extensively characterized in the visual domain, very little is known about tracking information in other sensory domains. Does tracking auditory information exhibit characteristics similar to those of tracking visual information, and to what extent do these two tracking tasks draw on the same attention resources? We addressed these questions by asking participants to perform either single or dual tracking tasks from the same (visual–visual) or different (visual–auditory) perceptual modalities, with the difficulty of the tracking tasks being manipulated across trials. The results revealed that performing two concurrent tracking tasks, whether they were in the same or different modalities, affected tracking performance as compared to performing each task alone (concurrence costs). Moreover, increasing task difficulty also led to increased costs in both the single-task and dual-task conditions (load-dependent costs). The comparison of concurrence costs between visual–visual and visual–auditory dual-task performance revealed slightly greater interference when two visual tracking tasks were paired. Interestingly, however, increasing task difficulty led to equivalent costs for visual–visual and visual–auditory pairings. We concluded that visual and auditory tracking draw largely, though not exclusively, on common central attentional resources.     

Microaggressions and Perceptions of Cultural Humility in Counseling

The purpose of this study was to explore how microaggressions affect counseling outcomes. Participants were 128 racial/ethnic minority individuals who had been in counseling within the past year. Results indicated that identity attributions were associated with counseling outcomes (i.e., working alliance and perceived improvement in counseling). Furthermore, perceptions of cultural humility mediated the relationship between negative emotion due to rupture and counseling outcomes (i.e., working alliance and perceived improvement in counseling).     

Conscientiousness and fruit and vegetable consumption: exploring behavioural intention as a mediator

Clear associations have emerged between conscientiousness and health behaviours, such that higher levels of conscientiousness are predictive of beneficial health behaviours. This study investigated the conscientiousness-fruit and vegetable consumption relationship and whether behavioural intention mediated this relationship. A large sample of adults (N = 2136) completed an online battery of questionnaires measuring conscientiousness, behavioural intentions to consume fruit and vegetables, together with self-reported behaviour. Correlation analysis revealed that conscientiousness and each of its facets were positively associated with behavioural intention and self-reported behaviour. Hierarchical multiple regression analyses revealed that after controlling for age, gender and education, total conscientiousness, and the facets of responsibility, industriousness, order and virtue predicted self-reported behaviour. Further analysis revealed that in line with the Theory of Planned Behaviour, behavioural intention fully mediated the conscientiousness-fruit and vegetable behaviour relationship. In conclusion, low levels of conscientiousness were found to be associated with lower fruit and vegetable intentions, with the latter also associated with fruit and vegetable consumption.     

Distinguishing intellectual humility and general humility

Two studies provide evidence for distinguishing intellectual humility (IH) from general humility (GH). Humility involves (a) an Accurate View of Self and (b) the ability to regulate egotism and cultivate an other-oriented stance; IH is a subdomain of humility that involves (a) having an accurate view of one’s intellectual strengths and limitations and (b) the ability to negotiate ideas in a fair and inoffensive manner. First, we present a theoretical framework for distinguishing these constructs. In Study 1, with a sample of undergraduate students (N = 1097), we used confirmatory factor analysis to provide empirical evidence for this distinction. We also found that IH predicted unique variance in openness to experience relative to GH. In Study 2, we examined additional evidence of discriminant validity with another sample of college students (N = 355). IH also predicted unique variance in need for cognition, objectivism, and religious ethnocentrism relative to GH.

Research priorities for the COVID-19 pandemic and beyond: A call to action for psychological science

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that has caused the coronavirus disease 2019 (COVID-19) pandemic represents the greatest international biopsychosocial emergency the world has faced for a century, and psychological science has an integral role to offer in helping societies recover. The aim of this paper is to set out the shorter- and longer-term priorities for research in psychological science that will (a) frame the breadth and scope of potential contributions from across the discipline; (b) enable researchers to focus their resources on gaps in knowledge; and (c) help funders and policymakers make informed decisions about future research priorities in order to best meet the needs of societies as they emerge from the acute phase of the pandemic. The research priorities were informed by an expert panel convened by the British Psychological Society that reflects the breadth of the discipline; a wider advisory panel with international input; and a survey of 539 psychological scientists conducted early in May 2020. The most pressing need is to research the negative biopsychosocial impacts of the COVID-19 pandemic to facilitate immediate and longer-term recovery, not only in relation to mental health, but also in relation to behaviour change and adherence, work, education, children and families, physical health and the brain, and social cohesion and connectedness. We call on psychological scientists to work collaboratively with other scientists and stakeholders, establish consortia, and develop innovative research methods while maintaining high-quality, open, and rigorous research standards.
