Editorial.

It is impossible to write this editorial without recognizing that we are living in challenging times. Unprecedented changes in how, when, where, and with whom we work have occurred in response to the COVID-19 pandemic. In addition to the threat to human life, the pandemic is expected to increase poverty and deepen preexisting inequalities for vulnerable groups such as women (United Nations, 2020) and individuals living in poorer countries (United Nations Development Programme, 2020). In the United States, the pandemic has disproportionately negatively affected racial and ethnic minority group members (https://www.cdc.gov/coronavirus/2019-ncov/community/health-equity/race-ethnicity.html). For example, in the United States infection and mortality rates are especially high among African Americans (Yancy, 2020). These sobering realities, along with the recent deaths of George Floyd, Ahmaud Arbery, and Breonna Taylor, and so many others, are vivid and wrenching reminders of longstanding social injustice and systematic racism, both in the United States and around the globe. When preparing my candidate statement and vision for the journal, a global pandemic and widespread social protest were the furthest thing from my mind. However, several aspects of my vision for JAP are highly relevant to the current context. This includes increasing representation and supporting diversity, as well as improving the translation of our science for the public good. Other elements of my vision for the journal include enhancing the review process and promoting open science. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Detainee and layperson's expectations and preferences regarding police interview rooms.

Emerging research on how suspects perceive the physical environment during investigative interviews yields contrasting findings. While previous studies have suggested that a room made to be physically comfortable may be optimal for interviewing suspects, another study found it can instead lead to higher suspicion of the investigator's intentions. The current study examined current detainees' and general population participants' beliefs about a room that resembled a "typical" interview room, and one decorated to be warm, inviting, and comfortable. Participants also provided descriptive information about their perceptions of police interview environments (e.g., preferences, expectations). We hypothesized that the decorated room would elicit higher ratings of suspicion and wariness compared to the "typical" room. Our findings showed that, overall, participants expected to be interviewed in the "typical" room but preferred the decorated one. Contrary to our expectations, they rated the "typical" room higher on feelings of suspicion than the decorated room. The decorated room also corresponded with what participants reported to be an environment that promotes disclosure. These results bode well for conducting investigative interviews in comfortable environments.

Selecting response anchors with equal intervals for summated rating scales.

Summated rating scales are ubiquitous in organizational research, and there are well-delineated guidelines for scale development (e.g., Hinkin, 1998). Nevertheless, there has been less research on the explicit selection of the response anchors. Constructing survey questions with equal-interval properties (i.e., interval or ratio data) is important if researchers plan to analyze their data using parametric statistics. As such, the primary objectives of the current study were to (a) determine the most common contexts in which summated rating scales are used (e.g., agreement, similarity, frequency, amount, and judgment), (b) determine the most commonly used anchors (e.g., strongly disagree, often, very good), and (c) provide empirical data on the conceptual distance between these anchors. We present the mean and standard deviation of scores for estimates of each anchor and the percentage of distribution overlap between the anchors. Our results provide researchers with data that can be used to guide the selection of verbal anchors with equal-interval properties so as to reduce measurement error and improve confidence in the results of subsequent analyses. We also conducted multiple empirical studies to examine the consequences of measuring constructs with unequal-interval anchors. A clear pattern of results is that correlations involving unequal-interval anchors are consistently weaker than correlations involving equal-interval anchors.

Modeling (in)congruence between dependent variables: The directional and nondirectional difference (DNDD) framework.

This article proposes a new approach to modeling the antecedents of incongruence between 2 dependent variables. In this approach, incongruence is decomposed into 2 orthogonal components representing directional and nondirectional difference (DNDD). Nondirectional difference is further divided into components representing shared and unique variability. We review previous approaches to modeling antecedents of difference, including the use of arithmetic, absolute, and squared differences, as well as the approaches of Edwards (1995) and Cheung (2009). Based on 2 studies, we demonstrate the advantages of DNDD approach compared with other methods. In the first study, we use a Monte Carlo simulation to demonstrate the circumstances under which each type of difference arises, and we compare the insights revealed by each approach. In the second study, we provide an illustrative example of DNDD approach using a field dataset. In the discussion, we review the strengths and limitations of our approach and propose several practical applications. Our article proposes 2 extensions to the basic DNDD approach, including modeling difference with a known target or "true" value, and using multilevel analysis to model nondirectional difference with exchangeable ratings.

The accuracy of dominance analysis as a metric to assess relative importance: The joint impact of sampling error variance and measurement unreliability.

Dominance analysis (DA) has been established as a useful tool for practitioners and researchers to identify the relative importance of predictors in a linear regression. This article examines the joint impact of two common and pervasive artifacts-sampling error variance and measurement unreliability-on the accuracy of DA. We present Monte Carlo simulations that detail the decrease in the accuracy of DA in the presence of these artifacts, highlighting the practical extent of the inferential mistakes that can be made. Then, we detail and provide a user-friendly program in R (R Core Team, 2017) for estimating the effects of sampling error variance and unreliability on DA. Finally, by way of a detailed example, we provide specific recommendations for how researchers and practitioners should more appropriately interpret and report results of DA.

Factores humanos en aviación: CRM (crew resource management-gestión de recursos de la tripulación) / Human factors in aviation: CRM (crew resource management)

Uno de los campos aplicados a los que más ha contribuido la ciencia psicológica es, sin lugar a dudas, el de la aviación. El análisis y estudio de los factores humanos constituye actualmente uno de los puntos fuertes en el sector aeronáutico de cara a la reducción de los accidentes aéreos. Desde su aparición en 1979, los programas de Gestión de Recursos de la Tripulación (CRM) han sido una de las herramientas que con mayor éxito han gestionado el denominado "error humano". El presente artículo realiza un breve recorrido por la historia de estos programas globales de entrenamiento que suponen uno de los grandes logros de la Psicología Aplicada

One of the applied fields to which psychological science has most contributed is, without doubt, aviation. The analysis and study of human factors is currently one of the strong points in the aeronautical sector in order to reduce accidents in aviation. Since its appearance in 1979, the Crew Resource Management (CRM) programs have been one of the most successful tools that have managed the so-called "human error". This paper makes a brief tour through the history of these global training programs that represent one of the great achievements of Applied Psychology

Effects of psychological interventions on systemic levels of inflammatory biomarkers in humans: A systematic review and meta-analysis.

The purpose of the present investigation was to systematically review randomized controlled trials examining the effects of psychological interventions on inflammatory biomarkers in adult populations and to quantitatively analyze those effects by meta-analysis. Two researchers independently searched key electronic databases, selected eligible publications, extracted data, and evaluated methodological quality. Nineteen randomized controlled trials examining a total of 1510 participants were included. The overall combined effect size from pre to post psychological intervention on pro-inflammatory biomarker levels was statistically significant, showing an attenuating effect, although of a small magnitude (s' g = 0.15, p = .008, CI [0.04-0.26]). However, this effect was not maintained into the follow-up period (g < -0.01, p = .964, CI [-0.19-0.18]). Looking at the individual biomarkers assessed across studies, only C-reactive protein (CRP) was found to significantly decrease following psychological intervention. A number of moderation analyses were conducted, none of which reached statistical significance. However, the numerically largest - and significant - within-group effect size was obtained for the group of studies that had preselected participants based on elevated psychological distress (g = 0.29, p = .047). In conclusion, psychological interventions appear efficacious in reducing pro-inflammatory biomarker levels. Future studies are recommended to carefully select individuals based on inflammatory (e.g., the presence of low-grade inflammation) and/or psychological (e.g., psychological distress) criteria.

METHODOLOGICAL PLURALISM AND MIXED METHODOLOGY TO STRENGTHEN COMMUNITY PSYCHOLOGY RESEARCH: AN EXAMPLE FROM OXFORD HOUSE.

This article evaluates how a plurality of research methods has served a research program that has functioned in a much-needed area of research: the role of housing and recovery residences in addiction recovery. The review focuses on one mutually supportive recovery residence model, called Oxford House, which represents more than 1,700 democratic, self-governing residences. To date, there has been no comprehensive evaluation of the research methods used with Oxford House or any other recovery residence. In this article, research methods, including study designs and data analyses, are summarized for 114 peer-reviewed empirical studies that included data on Oxford Houses or Oxford House residents. This review of a pluralistic research program can inform community researchers about the value of recovery residences, the many ways in which recovery residences may be assessed, and the benefits of using multiple methods. Implications for future recovery residence research are discussed.

Verbal, Visual, and Intermediary Support for Child Witnesses with Autism During Investigative Interviews.

Three promising investigative interview interventions were assessed in 270 children (age 6-11 years): 71 with autism spectrum disorder (ASD) and 199 who were typically developing (TD). Children received 'Verbal Labels', 'Sketch Reinstatement of Context' or 'Registered Intermediary' interviews designed to improve interview performance without decreasing accuracy. Children with ASD showed no increases in the number of correct details recalled for any of the three interview types (compared to a Best-Practice police interview), whereas TD children showed significant improvements in the Registered Intermediary and Verbal Labels interviews. Findings suggested that children with ASD can perform as well as TD children in certain types of investigative interviews, but some expected benefits (e.g., of Registered Intermediaries) were not apparent in this study.

Not all nonnormal distributions are created equal: Improved theoretical and measurement precision.

We offer a four-category taxonomy of individual output distributions (i.e., distributions of cumulative results): (1) pure power law; (2) lognormal; (3) exponential tail (including exponential and power law with an exponential cutoff); and (4) symmetric or potentially symmetric (including normal, Poisson, and Weibull). The four categories are uniquely associated with mutually exclusive generative mechanisms: self-organized criticality, proportionate differentiation, incremental differentiation, and homogenization. We then introduce distribution pitting, a falsification-based method for comparing distributions to assess how well each one fits a given data set. In doing so, we also introduce decision rules to determine the likely dominant shape and generative mechanism among many that may operate concurrently. Next, we implement distribution pitting using 229 samples of individual output for several occupations (e.g., movie directors, writers, musicians, athletes, bank tellers, call center employees, grocery checkers, electrical fixture assemblers, and wirers). Results suggest that for 75% of our samples, exponential tail distributions and their generative mechanism (i.e., incremental differentiation) likely constitute the dominant distribution shape and explanation of nonnormally distributed individual output. This finding challenges past conclusions indicating the pervasiveness of other types of distributions and their generative mechanisms. Our results further contribute to theory by offering premises about the link between past and future individual output. For future research, our taxonomy and methodology can be used to pit distributions of other variables (e.g., organizational citizenship behaviors). Finally, we offer practical insights on how to increase overall individual output and produce more top performers. (PsycINFO Database Record

Twilight of dawn or of evening? A century of research methods in the Journal of Applied Psychology.

We offer a critical review and synthesis of research methods in the first century of the Journal of Applied Psychology. We divide the chronology into 6 periods. The first emphasizes the first few issues of the journal, which, in many ways, set us on a methodological course that we sail to this day, and then takes us through the mid-1920s. The second is the period through World War II, in which we see the roots of modern methodological concepts and techniques, including a transition from a discovery orientation to a hypotheticodeductive model orientation. The third takes us through roughly 1970, a period in which many of our modern-day practices were formed, such as reliance on null hypothesis significance testing. The fourth, from 1970 through 1989, sees an emphasis on the development of measures of critical constructs. The fifth takes us into the present, which is marked by greater plurality regarding data-analytic approaches. Finally, we offer a glimpse of possible and, from our perspective, desirable futures regarding research methods. Specifically, we highlight the need to conduct replications; study the exceptional and not just the average; improve the quality of the review process, particularly regarding methodological issues; emphasize design and measurement issues; and build and test more specific theories.

Individual differences and their measurement: A review of 100 years of research.

This article reviews 100 years of research on individual differences and their measurement, with a focus on research published in the Journal of Applied Psychology. We focus on 3 major individual differences domains: (a) knowledge, skill, and ability, including both the cognitive and physical domains; (b) personality, including integrity, emotional intelligence, stable motivational attributes (e.g., achievement motivation, core self-evaluations), and creativity; and (c) vocational interests. For each domain, we describe the evolution of the domain across the years and highlight major theoretical, empirical, and methodological developments, including relationships between individual differences and variables such as job performance, job satisfaction, and career development. We conclude by discussing future directions for individual differences research. Trends in the literature include a growing focus on substantive issues rather than on the measurement of individual differences, a differentiation between constructs and measurement methods, and the use of innovative ways of assessing individual differences, such as simulations, other-reports, and implicit measures.

Leadership in applied psychology: Three waves of theory and research.

Although in the early years of the Journal leadership research was rare and focused primarily on traits differentiating leaders from nonleaders, subsequent to World War II the research area developed in 3 major waves of conceptual, empirical, and methodological advances: (a) behavioral and attitude research; (b) behavioral, social-cognitive, and contingency research; and (c) transformational, social exchange, team, and gender-related research. Our review of this work shows dramatic increases in sophistication from early research focusing on personnel issues associated with World War I to contemporary multilevel models and meta-analyses on teams, shared leadership, leader-member exchange, gender, ethical, abusive, charismatic, and transformational leadership. Yet, many of the themes that characterize contemporary leadership research were also present in earlier research. (PsycINFO Database Record

One hundred years of employee turnover theory and research.

We review seminal publications on employee turnover during the 100-year existence of the Journal of Applied Psychology. Along with classic articles from this journal, we expand our review to include other publications that yielded key theoretical and methodological contributions to the turnover literature. We first describe how the earliest papers examined practical methods for turnover reduction or control and then explain how theory development and testing began in the mid-20th century and dominated the academic literature until the turn of the century. We then track 21st century interest in the psychology of staying (rather than leaving) and attitudinal trajectories in predicting turnover. Finally, we discuss the rising scholarship on collective turnover given the centrality of human capital flight to practitioners and to the field of human resource management strategy.

Job attitudes, job satisfaction, and job affect: A century of continuity and of change.

Over the past 100 years, research on job attitudes has improved in the sophistication of methods and in the productive use of theory as a basis for fundamental research into questions of work psychology. Early research incorporated a diversity of methods for measuring potential predictors and outcomes of job attitudes. Over time, methods for statistically assessing these relationships became more rigorous, but the field also became narrower. In recent years, developments in theory and methodology have reinvigorated research, which now addresses a rich panoply of topics related to the daily flow of affect, the complexity of personal motives and dispositions, and the complex interplay of attitude objects and motivation in shaping behavior. Despite these apparent changes, a review of the concepts and substantive arguments that underpin this literature have remained remarkably consistent. We conclude by discussing how we expect that these major themes will be addressed in the future, emphasizing topics that have proven to be enduring guides for understanding the ways that people construe and react to their appraisals of their work.

Solving the Supreme Problem: 100 years of selection and recruitment at the Journal of Applied Psychology.

This article reviews 100 years of research on recruitment and selection published in the Journal of Applied Psychology. Recruitment and selection research has been present in the Journal from the very first issue, where Hall (1917) suggested that the challenge of recruitment and selection was the Supreme Problem facing the field of applied psychology. As this article shows, the various topics related to recruitment and selection have ebbed and flowed over the years in response to business, legal, and societal changes, but this Supreme Problem has captivated the attention of scientist-practitioners for a century. Our review starts by identifying the practical challenges and macro forces that shaped the sciences of recruitment and selection and helped to define the research questions the field has addressed. We then describe the evolution of recruitment and selection research and the ways the resulting scientific advancements have contributed to staffing practices. We conclude with speculations on how recruitment and selection research may proceed in the future. Supplemental material posted online provides additional depth by including a summary of practice challenges and scientific advancements that affected the direction of selection and recruitment research and an outline of seminal articles published in the Journal and corresponding time line. The 100-year anniversary of the Journal of Applied Psychology is very much the celebration of recruitment and selection research, although predictions about the future suggest there is still much exciting work to be done.

100 years of training and development research: What we know and where we should go.

Training and development research has a long tradition within applied psychology dating back to the early 1900s. Over the years, not only has interest in the topic grown but there have been dramatic changes in both the science and practice of training and development. In the current article, we examine the evolution of training and development research using articles published in the Journal of Applied Psychology (JAP) as a primary lens to analyze what we have learned and to identify where future research is needed. We begin by reviewing the timeline of training and development research in JAP from 1918 to the present in order to elucidate the critical trends and advances that define each decade. These trends include the emergence of more theory-driven training research, greater consideration of the role of the trainee and training context, examination of learning that occurs outside the classroom, and understanding training's impact across different levels of analysis. We then examine in greater detail the evolution of 4 key research themes: training criteria, trainee characteristics, training design and delivery, and the training context. In each area, we describe how the focus of research has shifted over time and highlight important developments. We conclude by offering several ideas for future training and development research.

Taking stock of two relational aspects of organizational life: Tracing the history and shaping the future of socialization and mentoring research.

As part of the centennial celebration for the Journal of Applied Psychology, this article reviews the literature on organizational socialization and mentoring. Our review includes a comparison of organizational socialization and mentoring as processes for employee adjustment and development, the historical context that fueled the emergence of these two areas of study, and a chronological mapping of key foundations, trends, themes that emerged across time, and major milestones. Along the way, a special emphasis is placed on research published in the Journal of Applied Psychology and high impact work is highlighted. We conclude with a discussion of five areas for future research. Specifically, we outline ideas for bridging the socialization and mentoring literatures, better understanding and capturing dynamic processes across time, the development of multilevel theories and models, addressing causality, and considering the implications for organizational socialization and mentoring research based on how technology is changing the way we work.

Performance appraisal and performance management: 100 years of progress?

We review 100 years of research on performance appraisal and performance management, highlighting the articles published in JAP, but including significant work from other journals as well. We discuss trends in eight substantive areas: (1) scale formats, (2) criteria for evaluating ratings, (3) training, (4) reactions to appraisal, (5) purpose of rating, (6) rating sources, (7) demographic differences in ratings, and (8) cognitive processes, and discuss what we have learned from research in each area. We also focus on trends during the heyday of performance appraisal research in JAP (1970-2000), noting which were more productive and which potentially hampered progress. Our overall conclusion is that JAP's role in this literature has not been to propose models and new ideas, but has been primarily to test ideas and models proposed elsewhere. Nonetheless, we conclude that the papers published in JAP made important contribution to the filed by addressing many of the critical questions raised by others. We also suggest several areas for future research, especially research focusing on performance management. (PsycINFO Database Record

Rock influences spatial memory in adult rats, while classical music do not / El rock afecta la memoria espacial en ratas adultas, mientras que la música clásica no

Music can be used as a therapeutic tool and has several effects in cognitive and physiological functions. The aim of this work was to evaluate the effect of different musical pieces in spatial memory in adult male rats. A T maze was used to investigate spatial memory, with 2h and 6h inter trial interval between training and testing phases. Before training, animals were exposed to an active or relaxing musical stimulus corresponding to rock and classical pieces. It was found that in the experiment with 2h interval, animals explore more the novel arm in comparison with the other arm, which indicated that animals still had a good spatial memory. This was not observed in rats that were exposed to the relaxing rock piece, which could indicate that this stimulus diminished memory. With the 6h interval the rats explored both arms equally, except animals that were exposed to the activating rock piece of music which indicated a slightly enhance in memory. Thus, there were found different effects of music corresponding to the time of interval and the stimulus characteristics. This data provides information to use music as a possible treatment to modulate memory (AU)

La música puede ser usada como una herramienta terapéutica y ha demostrado tener múltiples efectos en las funciones cognitivas y fisiológicas. El objetivo de este trabajo fue evaluar el efecto de diferentes piezas musicales en la memoria espacial de ratas adultas macho. Se utilizó un laberinto en forma de T para evaluar la memoria espacial, con 2 y 6 horas de intervalo entre ensayos entre el entrenamiento y fase de testeo. Antes del entrenamiento los animales fueron expuestos a estímulos sonoros activantes o relajantes correspondientes a piezas de rock y música clásica. Se encontró que en el experimento con 2 horas de intervalo los animales exploraron más el brazo novedoso en comparación con el ya conocido, lo cual indica que los sujetos tenían un buen índice de memoria espacial. Esto no se observó en las ratas que fueron expuestas a la pieza de rock relajante, lo que indicaría que este estímulo disminuyó la memoria. Con el intervalo de 6 horas los animales exploraron ambos brazos por igual, excepto los que fueron expuestos a la pieza activante de rock, lo cual indicaría una mejora en la memoria. Con lo cual, se hallaron diferentes efectos de la música en relación al intervalo de tiempo aplicado entre entrenamiento y test, así como al tipo de estímulo empleado. Estos datos proveen información acerca del uso de la música como un posible tratamiento de modulación de la memoria (AU)
