Consecutive Shifts: A Repeated Measure Study to Evaluate Stress, Biomarkers, Social Support, and Fatigue in Medical/Surgical Nurses.

Nurses report that they are required to work during their scheduled breaks and generally experience extended work times and heavy workloads due to staffing shortages. This study aimed to examine changes in personal, work-related, and overall stress, as well as biological responses and fatigue experienced by nurses during three consecutive 12 h workdays (i.e., the typical "three-twelves" schedule). We also considered the moderating effects of social resources. This prospective study of 81 medical/surgical nurses who completed questionnaires and provided saliva samples at four designated intervals (i.e., pre-shift and post-shift on workdays 1 and 3). Fatigue reported by night shift nurses increased significantly over three consecutive workdays (p = 0.001). Day shift nurses said they encountered more social support than those on the night shift (p = 0.05). Social support moderated the relationship between work-related stress at baseline and reported fatigue on day 3.

Aging and Burnout for Nurses in an Acute Care Setting: The First Wave of COVID-19.

We examined the relationship between age, coping, and burnout during the peak of the COVID-19 pandemic with nurses in Texas (N = 376). Nurses were recruited through a professional association and snowball sampling methodology for the cross-sectional survey study. Framed in lifespan development theories, we expected that nurse age and experience would be positively correlated with positive coping strategies (e.g., getting emotional support from others) and negatively correlated with negative coping strategies (e.g., drinking and drug use). We also expected age to be negatively related to the emotional exhaustion and depersonalization facets of burnout and positively related to the personal accomplishment facet of burnout. Findings were largely supported in that age was positively associated with positive coping and personal accomplishment and age and experience were negatively correlated with negative coping and depersonalization. Age was not, however, associated with emotional exhaustion. Mediation models further suggest that coping explains some of the effect of age on burnout. A theoretical extension of lifespan development models into an extreme environment and practical implications for coping in these environments are discussed.

Objective Communication Patterns Associated With Team Member Effectiveness in Real-World Virtual Teams.

OBJECTIVE: We explore the relationships between objective communication patterns displayed during virtual team meetings and established, qualitative measures of team member effectiveness. BACKGROUND: A key component of teamwork is communication. Automated measures of objective communication patterns are becoming more feasible and offer the ability to measure and monitor communication in a scalable, consistent and continuous manner. However, their validity in reflecting meaningful measures of teamwork processes are not well established, especially in real-world settings. METHOD: We studied real-world virtual student teams working on semester-long projects. We captured virtual team meetings using the Zoom video conferencing platform throughout the semester and periodic surveys comprising peer ratings of team member effectiveness. Leveraging audio transcripts, we examined relationships between objective measures of speaking time, silence gap duration and vocal turn-taking and peer ratings of team member effectiveness. RESULTS: Speaking time, speaking turn count, degree centrality and (marginally) speaking turn duration, but not silence gap duration, were positively related to individual-level team member effectiveness. Time in dyadic interactions and interaction count, but not interaction length, were positively related to dyad-level team member effectiveness. CONCLUSION: Our study highlights the relevance of objective measures of speaking time and vocal turn-taking to team member effectiveness in virtual project-based teams, supporting the validity of these objective measures and their use in future research. APPLICATION: Our approach offers a scalable, easy-to-use method for measuring communication patterns and team member effectiveness in virtual teams and opens the opportunity to study these patterns in a more continuous and dynamic manner.

The domain-specificity of serial order working memory.

Making a turn while driving is simple: turn on the indicator, check for cars, then turn. Two types of information are required to perform this sequence of events: information about the items (e.g., the correct indicator), and the serial order of those items (e.g., checking before turning rather than vice-versa). Previous research has found distinct working memory capacities (WMCs) for item and serial order information in both verbal and nonverbal domains. The current study investigates whether the serial order WMC is shared for sequences from different content domains. One hundred and fifty-three participants performed sequence matching tasks with verbal (letters and words) and nonverbal (locations and arrows) stimuli. The accuracy of detecting mismatched item-identity and serial order information in sequences was used to operationalize item and order WMC. Using structural equation modeling analyses, we directly compared models that included either domain-specific or domain-general serial order WMC latent variables, finding that models with domain-specific serial order WMC latent variables for verbal and nonverbal materials fit the data better than models with domain-general latent variables. The findings support the hypothesis that there are separate capacities for serial order working memory depending on the type of material being ordered.

A Meta-analysis of University STEM Summer Bridge Program Effectiveness.

University science, technology, engineering, and math (STEM) summer bridge programs provide incoming STEM university students additional course work and preparation before they begin their studies. These programs are designed to reduce attrition and increase the diversity of students pursuing STEM majors and STEM career paths. A meta-analysis of 16 STEM summer bridge programs was conducted. Results showed that program participation had a medium-sized effect on first-year overall grade point average (d = 0.34) and first-year university retention (Odds Ratio [OR] = 1.747). Although this meta-analytic research reflects a limited amount of available quantitative academic data on summer STEM bridge programs, this study nonetheless provides important quantitative inroads into much-needed research on programs' objective effectiveness. These results articulate the importance of thoughtful experimental design and how further research might guide STEM bridge program development to increase the success and retention of matriculating STEM students.

Nurse Adaptability and Post-traumatic Stress Disorder Symptoms During the COVID-19 Pandemic: The Effects of Family and Perceived Organizational Support.

Objective: To examine the effect of family and perceived organizational support on the relationship between nurse adaptability and their experience with COVID-related PTSD (post-traumatic stress disorder) symptoms in frontline nurses working on COVID-19 units. Background: Proximity to and survival of life-threatening events contribute to a diagnosis of PTSD, which is characterized by avoidance of reminders of trauma, intrusive thoughts, flashbacks of events, sleep disturbances, and hypervigilance. Using the job-demands and resource model, we examined the effect of adaptability, family support, and perceived organizational support on PTSD symptoms for nurses during the COVID-19 pandemic. Specifically, we tested whether perceptions of environmental supports-i.e., family and organizational support-moderated the relationship between nurse adaptability and COVID-related PTSD symptoms. Methods: A sample of frontline nurses working on COVID-19 units during the COVID-19 pandemic in Texas (N = 277) participated in this cross-sectional, observational study. Frontline Nurses reported demographic information and completed surveys designed to measure adaptability, perceived organizational support, family support, and COVID-related PTSD symptoms. Results: Adaptability was significantly positively correlated (medium effects) to perceived organizational and family support (r = 0.51 and 0.56, respectively, p < 0.01). Adaptability and perceived organizational support were also negatively correlated with COVID-related PTSD symptoms (medium effects). Adaptability was negatively correlated with COVID-related PTSD symptoms, supporting Hypothesis 1 (r = -0.43, p < 0.01). Perceived organizational support was also significantly negatively correlated with COVID-19-related PTSD symptoms (r = -0.30, p < 0.01). Family support was not significantly correlated with COVID-related PTSD but was positively related to experiencing COVID-related PTSD after other variables were accounted for. Conclusion: Findings suggest that individual adaptability and organizational support may reduce PTSD severity in frontline nurses working during a crisis; however, family support may increase PTSD symptoms. We provide suggestions for strengthening individual adaptability and healthcare leadership including remaining highly engaged to show support by providing rapid communication, remaining calm during difficult circumstances, and maintaining a consistent, physical presence during difficult times. Moreover, our results suggest additional support for nurses with families to adapt to crisis.

Age and job fit: The relationship between demands-ability fit and retirement and health.

Understanding the antecedents of retirement and health is increasingly important given the proportion of older adults in the global workforce. The current study examines the relationship between the demands-ability facet of person-job fit and retirement status and health. The sample consists of older workers and retired adults (N = 383) from the Study of Cognition and Aging in the U.S.A. (a national study of age and cognitive abilities). Objective demands-ability fit was operationalized as the fit between a person's cognitive abilities assessed with an extensive battery of reasoning (fluid abilities) and knowledge (crystallized abilities) and relevant job demands taken from the Occupational Information Network. Results indicated that as the congruence between workers' reasoning abilities and job demands increased, workers reported fewer chronic health conditions. When reasoning abilities required by a job exceeded worker abilities, workers reported more health conditions and were more likely to be retired versus working. Fewer health conditions were reported when reasoning abilities exceeded reasoning job demands. Congruence for knowledge abilities and demands fit was significant only at medium levels of knowledge abilities and demands. Overall, these results suggest that demands-ability fit is relevant to the experience of work in older age. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Commenting on the "Great Debate": General Abilities, Specific Abilities, and the Tools of the Trade.

We review papers in the special issue regarding the great debate on general and specific abilities. Papers in the special issue either provided an empirical examination of the debate using a uniform dataset or they provided a debate commentary. Themes that run through the papers and that are discussed further here are that: (1) the importance of general and specific ability predictors will largely depend on the outcome to be predicted, (2) the effectiveness of both general and specific predictors will largely depend on the quality and breadth of how the manifest indicators are measured, and (3) research on general and specific ability predictors is alive and well and more research is warranted. We conclude by providing a review of potentially fruitful areas of future research.

Multiple routes to mind wandering: Predicting mind wandering with resource theories.

Three experiments examine individual (attentional capacity) and task-related characteristics leading to mind wandering, and the effect of mind wandering on task performance. Drawing on resource theories, we tested interactive nonlinear effects of these predictors, manipulating task demand using math tests of varying difficulty (Exp 1: N = 143, three levels between-subjects; Exp 2: N = 59, three levels within-subjects; Exp 3: N = 133, four levels within-subjects). Results confirmed that mind wandering was most frequent during extreme task demand levels, although the effect varied somewhat between experiments. Additionally, results from Experiment 3 and an integrated analysis demonstrated that people with relatively higher attentional capacity were less likely to mind wander as task demand increased. Moreover, mind wandering was more detrimental to performance as task demand increased across all experiments. Our findings build on past research by demonstrating the importance of accounting for interactions and nonlinear effects of task demand and attentional capacity in mind wandering research.

Mind-wandering, cognition, and performance: a theory-driven meta-analysis of attention regulation.

The current meta-analysis accumulates empirical findings on the phenomenon of mind-wandering, integrating and interpreting findings in light of psychological theories of cognitive resource allocation. Cognitive resource theory emphasizes both individual differences in attentional resources and task demands together to predict variance in task performance. This theory motivated our conceptual and meta-analysis framework by introducing moderators indicative of task-demand to predict who is more likely to mind-wander under what conditions, and to predict when mind-wandering and task-related thought are more (or less) predictive of task performance. Predictions were tested via a random-effects meta-analysis of correlations obtained from normal adult samples (k = 88) based on measurement of specified episodes of off-task and/or on-task thought frequency and task performance. Results demonstrated that people with fewer cognitive resources tend to engage in more mind-wandering, whereas those with more cognitive resources are more likely to engage in task-related thought. Addressing predictions of resource theory, we found that greater time-on-task-although not greater task complexity-tended to strengthen the negative relation between cognitive resources and mind-wandering. Additionally, increases in mind-wandering were generally associated with decreases in task performance, whereas increases in task-related thought were associated with increased performance. Further supporting resource theory, the negative relation between mind-wandering and performance was more pronounced for more complex tasks, though not longer tasks. Complementarily, the positive association between task-related thought and performance was stronger for more complex tasks and for longer tasks. We conclude by discussing implications and future research directions for mind-wandering as a construct of interest in psychological research.

Teaching the biological consequences of alcohol abuse through an online game: impacts among secondary students.

A multimedia game was designed to serve as a dual-purpose intervention that aligned with National Science Content Standards, while also conveying knowledge about the consequences of alcohol consumption for a secondary school audience. A tertiary goal was to positively impact adolescents' attitudes toward science through career role-play experiences within the game. In a pretest/delayed posttest design, middle and high school students, both male and female, demonstrated significant gains on measures of content knowledge and attitudes toward science. The best predictors of these outcomes were the players' ratings of the game's usability and satisfaction with the game. The outcomes suggest that game interventions can successfully teach standards-based science content, target age-appropriate health messages, and impact students' attitudes toward science.

Is cognitive ability a liability? A critique and future research agenda on skilled performance.

Over a century of psychological research provides strong and consistent support for the idea that cognitive ability correlates positively with success in tasks that people face in employment, education, and everyday life. Recent experimental research, however, has converged on a different and provocative conclusion, namely that lower-ability people can actually be more effective performers within special environments characterized by features such as time pressure, social evaluation, and unpredictable task change. If this conclusion is true, it has extensive implications for practices such as personnel selection, training design, and teaching methods. The current article reexamines and reinterprets this research within the context of well-established resource theories of cognitive processing and skill acquisition leading to a less provocative conclusion that serves to reiterate the benefits of cognitive ability for task performance. Following this reexamination, we conclude by providing a research agenda for examining the determinants of skilled performance in dynamic task environments, including the following: (a) broadening the range of abilities and task difficulties examined, (b) considering the role of nonability traits and goals in skilled performance (e.g., personality, learning, and performance goals), (c) investigating the processes (e.g., problem solving strategies) that people use in complex environments, (d) developing research designs and analytic strategies for examining adaptive performance, and (e) investigating how best to train for adaptive performance.

Differentiating specific job knowledge from implicit trait policies in procedural knowledge measured by a situational judgment test.

This study compared validities of situational judgment test (SJT) scoring keys that were presumed to be differentially saturated with specific knowledge about effective job behavior and general knowledge about effective trait expression. The keys were based on subject matter experts' effectiveness judgments, undergraduates' effectiveness judgments, and graduate students' trait judgments. We used data reported earlier by Motowidlo, Dunnette, and Carter (1990) with managerial incumbents in telecommunication companies. All keys yielded valid relations with supervisory performance ratings. The key based on subject matter experts' judgments, however, explained criterion variance beyond the variance explained by the other keys. These results suggest that specific knowledge about effective job behavior and general knowledge about effective trait expression (i.e., implicit trait policies) contribute independently to variance in job performance.

When training with a partner is inferior to training alone: the importance of dyad type and interaction quality.

Dyad training, where trainees learn in pairs but ultimately perform individually, has been shown to be an effective method for training some skills. The effectiveness of this approach, however, may be tied to the type of task to be trained and the quality of the interaction in the dyad. We report two studies on the effectiveness of dyad training and the role of metacognitive activity for learning a software program. In Study 1, participants completed training alone or with a partner. Performance was assessed individually immediately after training and again after a 1-week nonuse interval. Results of Study 1 suggested that learning retention is superior when people are trained individually. Study 2 examined performance for individuals, task-switching dyads, and interdependent dyads. Results also showed that performance for individuals was superior to dyads and that the type of dyad collaboration did not affect performance. However, partner-prompted metacognitive activity was helpful for interdependent dyads and harmful for task-switching dyads, suggesting that the quality of collaboration varies by dyad type. Our findings suggest that dyad training may not be effective for all types of tasks. Possible boundary conditions for effective dyad training are discussed.

Executive function in older adults: a structural equation modeling approach.

Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used to study the organization of executive functions in older adults. The four primary goals were to examine (a) whether executive functions were supported by one versus multiple underlying factors, (b) which underlying skill(s) predicted performance on complex executive function tasks, (c) whether performance on analogous verbal and nonverbal tasks was supported by separable underlying skills, and (d) how patterns of performance generally compared with those of young adults. A sample of 100 older adults completed 10 tasks, each designed to engage one of three control processes: mental set shifting (Shifting), information updating or monitoring (Updating), and inhibition of prepotent responses (Inhibition). CFA identified robust Shifting and Updating factors, but the Inhibition factor failed to emerge, and there was no evidence for verbal and nonverbal factors. SEM showed that Updating was the best predictor of performance on each of the complex tasks the authors assessed (the Tower of Hanoi and the Wisconsin Card Sort). Results are discussed in terms of insight for theories of cognitive aging and executive function.

Further explorations of perceptual speed abilities in the context of assessment methods, cognitive abilities, and individual differences during skill acquisition.

Measures of perceptual speed ability have been shown to be an important part of assessment batteries for predicting performance on tasks and jobs that require a high level of speed and accuracy. However, traditional measures of perceptual speed ability sometimes have limited cost-effectiveness because of the requirements for administration and scoring of paper-and-pencil tests. There have also been concerns about the validity of previous computer approaches to administering perceptual speed tests (e.g., see Mead & Drasgow, 1993). The authors developed two sets of computerized perceptual speed tests, with touch-sensitive monitors, that were designed to parallel several paper-and-pencil tests. The reliability and validity of the tests were explored across three empirical studies (N = 167, 160, and 117, respectively). The final study included two criterion tasks with 4.67 and 10 hours of time-on-task practice, respectively. Results indicated that these new measures provide both high levels of reliability and substantial validity for performance on the two skill-learning tasks. Implications for research and application for computerized perceptual speed tests are discussed.

Age, ability, and the role of prior knowledge on the acquisition of new domain knowledge: promising results in a real-world learning environment.

Prior knowledge, fluid intelligence (Gf), and crystallized intelligence (Gc) were investigated as predictors of learning new information about cardiovascular disease and xerography with a sample of 199 adults (19 to 68 years). The learning environment included a laboratory multimedia presentation (high-constraint-maximal effort), and a self-directed at-home study component (low-constraint-typical performance). Results indicated that prior knowledge and ability were important predictors of knowledge acquisition for learning. Gc was directly related to learning from the video for both domains. Because the trajectory of Gc stays relatively stable throughout the life span, these findings provide a more optimistic perspective on the relationship between aging and learning than that offered by theories that focus on the role of fluid abilities in learning.

Working memory and intelligence: the same or different constructs?

Several investigators have claimed over the past decade that working memory (WM) and general intelligence (g) are identical, or nearly identical, constructs, from an individual-differences perspective. Although memory measures are commonly included in intelligence tests, and memory abilities are included in theories of intelligence, the identity between WM and intelligence has not been evaluated comprehensively. The authors conducted a meta-analysis of 86 samples that relate WM to intelligence. The average correlation between true-score estimates of WM and g is substantially less than unity (p=.479). The authors also focus on the distinction between short-term memory and WM with respect to intelligence with a supplemental meta-analysis. The authors discuss how consideration of psychometric and theoretical perspectives better informs the discussion of WM-intelligence relations.

Determinants of health knowledge: an investigation of age, gender, abilities, personality, and interests.

Ten areas of health knowledge were investigated in 2 studies, 1 of college students (N = 169) and 1 of adults from the community (ages 19-70; N = 176). Measures assessed knowledge of aging, orthopedic/dermatological concerns, common illnesses, childhood/early life, serious illnesses, mental health, nutrition, reproduction, safety, and treatment of illness/disease. Significant gender differences favoring women were found for most areas of health knowledge, especially reproduction and early life. Results showed that cognitive ability accounted for the most variance in health knowledge with nonability (personality and interest traits) and demographic variables accounting for smaller but significant amounts of variance across most knowledge domains.

Individual differences in working memory within a nomological network of cognitive and perceptual speed abilities.

It has become fashionable to equate constructs of working memory (WM) and general intelligence (g). Few investigations have provided direct evidence that WM and g measures yield similar ordering of individuals. Correlational investigations have yielded mixed results. The authors assess the construct space for WM and g and demonstrate that WM shares substantial variance with perceptual speed (PS) constructs. Thirty-six ability tests representing verbal, numerical, spatial, and PS abilities; the Raven Advanced Progressive Matrices; and 7 WM tests were administered to 135 adults. A nomological representation for WM is provided through a series of cognitive and PS ability models. Construct overlap between PS and WM is further investigated with attention to complexity, processing differences, and practice effects.
