Causality of the Satisfaction-Performance Relationship: A Task Experiment.

Despite the common belief among practitioners that a happy worker is a productive worker, researchers have been struggling to understand the causality between satisfaction and performance for decades. This study attempts to bring clarity to current understanding through an experiment with repeated measures of satisfaction and performance. A total of 143 participants repeatedly performed a task based on the Stroop test, with their objective performance and task satisfaction measured each time. Two different types of feedback (high/low performance) were randomly assigned to participants in order to manipulate perceived performance. The data were analyzed using a path analysis. The results support the hypothesized influence of task satisfaction on task performance and of perceived task performance on task satisfaction.

Reflection and Reasoning in Moral Judgment: Two Preregistered Replications of Paxton, Ungar, and Greene (2012).

This study consists of two preregistered systematic replications of an experiment on reflection and reasoning in moral judgment by Paxton, Ungar, and Greene (2012). Czech students read a scenario involving incest between consenting adult siblings and an argument supporting the moral acceptability of the behavior. We manipulated the factors of argument strength (strong vs. weak) and the time that participants had to reflect on the argument (no time vs. 2 min). In the first replication (n = 347), neither the manipulated factors nor their interaction influenced how participants rated the moral acceptability of the incestuous behavior. The only significant predictor in the second replication (n = 717) was argument strength but with a very small effect. The effect of argument strength did not differ across groups either with or without deliberation time. Therefore, neither of the studies replicated the effect that deliberation time moderates the influence of argument strength on moral judgment, even though the samples were considerably larger than in the original study. We thus conclude that the effect of the interaction between the strength of an argument and deliberation time on moral judgment either does not exist or is moderated by certain contextual or sample characteristics.

Pain as Social Glue: A Preregistered Direct Replication of Experiment 2 of Bastian et al. (2014).

Bastian et al. (2014) found that sharing a painful experience promoted later intergroup cooperation. In Bastian et al.'s second experiment, 62 participants were assigned to groups of two to six people each. They performed either two painful or two painless tasks and then played an economic game. The present study consisted of two replications of the experiment: The first was a nonpreregistered pilot study (N = 153 students from the Czech Republic), and the second was a preregistered direct replication (N = 158 students from Slovakia). Important deviations from the original procedure were that (a) gender homogeneity of the small groups was balanced across the conditions and (b) the number of participants in each small group was fixed at three. No relevant effect of shared pain on cooperation emerged. The findings indicate that the true effect of shared pain on cooperation obtained in the original study may have been an overestimate or that the effect is not generally valid across various contexts.

The effect of font readability on the Moses illusion: A replication study.

This research is a replication study that sought to verify whether the readability of a font has an effect on the Moses illusion detection. It was designed to stimulate information retrieval from memory and confuse retrieval with a text's erroneous wording. Undergraduates aged 19-30 (N = 87, 80% women) were presented with two questions, one of which contained distorted information. We assumed that a difficult-to-read font would facilitate error detection, as it increases the focus of attention on the text. However, unlike the original study, we were unable to find support for this hypothesis, as font readability did not significantly affect error detection. In the difficult-to-read condition, 43% of participants reported an error, while, in the easy-to-read condition, errors were detected by 37% of the participants. Unlike the original study, our research results do not support the hypothesis that the visual presentation of a text affects the automatic retrieval of information from memory. This study clarifies the effect of text readability on error detection taking into consideration the role of long-term memory and visual perception.

Working during the COVID-19 pandemic: Demands, resources, and mental wellbeing.

The aim of this study was to investigate the relationship between working conditions at the start of the COVID-19 pandemic (spring 2020) and employees' mental wellbeing. According to the Job Demands-Resources (JD-R) model, work intensification, increased difficulty in accomplishing work tasks, heightened risk of infection by COVID-19, and increasingly working from home may detrimentally relate to irritation. However, personal and job resources (e.g., occupational self-efficacy, social support) may buffer. Data from 680 employees from four European countries were analyzed by means of path analyses and polynomial regression. Work intensification was significantly positively associated with cognitive and affective irritation; other job demands were not. However, working from home prior to as well as during the pandemic was related to higher cognitive irritation. None of the moderators was of meaningful significance. Reducing work intensification as well as enduring home office seems to be crucial for interventions.

Can the color red trick you into drinking less? A replication study.

This replication of the study of Genschow et al. (2012) examines the effect of the color red on beverage consumption. In total, 148 men were asked to consume drinks in either red- or blue-labeled cups. Cup labels were assigned at random. Unlike in the previous study, the findings in our replication study did not provide empirical support for the hypothesis that people will drink less from red-labeled cups than blue-labeled cups. The difference between groups in drink consumption was non-significant. Thus, the red color did not have an inhibitory effect on drink intake.

Measuring psychological capital: Revision of the Compound Psychological Capital Scale (CPC-12).

This article provides information about the psychometric limitations of the original Compound Psychological Capital Scale (CPC-12) and suggests a revised version CPC-12R, a free-to-use measure of Psychological Capital. The investigation consisted of three studies: two of these identified psychometric limitations of the original scale, and the third presented the revised version of the scale. The first study did not confirm the hypothesized four-factor structure of the CPC-12 on a sample of Czech teachers (n = 282) and found psychometric limitations in the resilience subscale. The second study identified the same problem using secondary analyses of the original data from two samples of German employees (n = 202 and 321 respectively). The third study proposed a revised version of the scale with new items for resilience, and provided support for reliability and factorial validity of the new CPC-12R on a sample of Czech employees (n = 333). CPC-12R demonstrated a better fit to the theoretically supported model of Psychological Capital than CPC-12, and further displays adequate psychometric properties to be recommended for application in both research and practice.

Data on work-related consequences of COVID-19 pandemic for employees across Europe.

The COVID-19 pandemic influenced the work of employees across all continents. This article presents raw data that may be used to describe how the pandemic affected the work of employees in four European countries and how it influenced their job attitudes, feelings and work performance. In total, 726 respondents from Germany, the Czech Republic, Slovakia and Italy filled out an extensive online survey and provided information about changes in their workload, work difficulty, income, social contact, work from home, task performance and organizational commitment during the pandemic, and about the risk of being infected by COVID-19 during their workday. The employees also reported their actual work performance, organizational commitment, job satisfaction, intention to leave and irritation in the time of the pandemic. To reveal factors that might help employees cope with pandemic, the respondents filled out established questionnaires measuring servant leadership of their supervisor, perceived organizational support, social support provided by colleagues, their own occupational self-efficacy, resilience, job crafting and readiness for change. The data is unique as it was collected in a specific situation during the pandemic, when the work of employees was affected by security measures and lockdown introduced by governments in countries where they worked.

Mind the Silver Bullet Thinking: A Multilevel Study on the Impact of Manager Trait Mindfulness on Subordinate Objective Job Performance.

This research examines the relationship between trait mindfulness of managers and job performance of their subordinates. We hypothesized that both are positively associated and that this association exist when personality variables are controlled for. We tested our hypotheses in a sample of 40 line managers and their 487 subordinates working in 40 teams within the customer service division of an energy company. We measured managers' trait mindfulness using the Five Factor Mindfulness Questionnaire (FFMQ) and managers' neuroticism and conscientiousness using the NEO-FFI. We obtained objective data of each subordinate's job performance captured by the company's KPIs assessed monthly over a period of 6 months. We used multilevel regression analyses to test our hypotheses. Results did not support our hypotheses, the regression coefficient from managers' trait mindfulness to subordinates' job performance was close to zero and insignificant. In the context of previously reported positive findings, our results suggest that the contribution of trait mindfulness to subordinates' performance might not exist or could be contingent on contextual factors.

The power of red: The influence of colour on evaluation and failure - A replication.

This replication of a study by >Rutchick, Slepian, and Ferris (2010) examines the influence of the colour of a pen on the activation of associations with failure and the focus on errors. We assigned two tasks to 198 students who completed them using either a red or a blue pen. The students were instructed to complete several word stems in the first task. In the second, we asked them to mark mistakes in a text. The participants using red pens completed significantly more word stems with words associated with failure than those using blue pens. The participants using red pens also marked significantly more mistakes in a text than those using blue pens. Our results support the findings of the original study and the hypothesized influence of the colour red in inducing a higher activation of associations with failure and a heightened focus on mistakes. Our study further contributes to research in this area in that it takes into account the participants' field of study and creates an explicit achievement context in which the observed phenomenon is most prevalent.

Plasmid-mediated quinolone resistance genes in fecal bacteria from rooks commonly wintering throughout Europe.

This study concerned the occurrence of fecal bacteria with plasmid-mediated quinolone resistance (PMQR) genes in rooks (Corvus frugilegus, medium-sized corvid birds) wintering in continental Europe during winter 2010/2011. Samples of fresh rook feces were taken by cotton swabs at nine roosting places in eight European countries. Samples were transported to one laboratory and placed in buffered peptone water (BPW). The samples from BPW were enriched and subcultivated onto MacConkey agar (MCA) supplemented with ciprofloxacin (0.06 mg/L) to isolate fluoroquinolone-resistant bacteria. DNA was isolated from smears of bacterial colonies growing on MCA and tested by PCR for PMQR genes aac(6')-Ib, qepA, qnrA, qnrB, qnrC, qnrD, qnrS, and oqxAB. All the PCR products were further analyzed by sequencing. Ciprofloxacin-resistant bacteria were isolated from 37% (392 positive/1,073 examined) of samples. Frequencies of samples with ciprofloxacin-resistant isolates ranged significantly from 3% to 92% in different countries. The qnrS1 gene was found in 154 samples and qnrS2 in 2 samples. The gene aac(6')-Ib-cr was found in 16 samples. Thirteen samples were positive for qnrB genes in variants qnrB6 (one sample), qnrB18 (one), qnrB19 (one), qnrB29 (one), and qnrB49 (new variant) (one). Both the qnrD and oqxAB genes were detected in six samples. The genes qnrA, qnrC, and qepA were not found. Wintering omnivorous rooks in Europe were commonly colonized by bacteria supposedly Enterobacteriaceae with PMQR genes. Rooks may disseminate these epidemiologically important bacteria over long distances and pose a risk for environmental contamination.
