Professional burnout

Abstract

Stress has been a ubiquitous concept in health research. We compare stress theories with the operationalization of stress in health research. Although scientific investigation is ideally based on theoretical principles, stress research is seen as often atheoretical or misapplying theories. Major conceptualizations of stress are considered and prominent research avenues in health psychology are analyzed as to the extent they mirror, diverge from, or inform stress conceptualizations. A central conclusion of the paper is that perceived and objective stressors are not only both valid construels of stress, but that they operate differently on psychological and physiological systems.     

Immediate as well as delayed post learning sleep but not wakefulness enhances declarative memory consolidation in children

While there is mounting evidence for the importance of sleep for declarative memory consolidation in adults, so far this issue has not been investigated in children despite considerable differences in sleep duration and sleep architecture between children and adults. Here, 27 children (aged between 9 and 12yr) were examined on two conditions: on the Sleep-Wake condition, subjects learned word pairs in the evening and delayed recall was tested first in the next morning after sleep and then again in the following evening after daytime wakefulness. On the Wake-Sleep condition, learning took place in the morning and delayed recall was tested in the evening of the same day and again in the next morning after sleep. In both conditions retention of declarative memory was significantly increased only after an interval of sleep that either followed immediately after learning (as in the Sleep-Wake condition) or that followed after daytime wakefulness (as in the Wake-Sleep condition), respectively. The results support the hypothesis that sleep plays an active role in declarative memory consolidation even if delayed and further show for the first time the importance of sleep for declarative memory consolidation during childhood.     

A simple technique to study embodied language processes: the grip force sensor

Research in cognitive neuroscience has shown that brain structures serving perceptual, emotional, and motor processes are also recruited during the understanding of language when it refers to emotion, perception, and action. However, the exact linguistic and extralinguistic conditions under which such language-induced activity in modality-specific cortex is triggered are not yet well understood. The purpose of this study is to introduce a simple experimental technique that allows for the online measure of language-induced activity in motor structures of the brain. This technique consists in the use of a grip force sensor that captures subtle grip force variations while participants listen to words and sentences. Since grip force reflects activity in motor brain structures, the continuous monitoring of force fluctuations provides a fine-grained estimation of motor activity across time. In other terms, this method allows for both localization of the source of language-induced activity to motor brain structures and high temporal resolution of the recorded data. To facilitate comparison of the data to be collected with this tool, we present two experiments that describe in detail the technical setup, the nature of the recorded data, and the analyses (including justification about the data filtering and artifact rejection) that we applied. We also discuss how the tool could be used in other domains of behavioral research.     

Activity experiences shape perceived fitness trajectories: results from a 6-month randomized controlled trial in older women

In this study we addressed the subjective benefits of activity interventions that were designed to improve cognitive fitness in old age. Two hundred and fifty-nine women (aged 70-93 years) were randomized to participate in an exercise or a computer course or a control condition for 6 months. Subjective ratings of the perceived change of cognitive and physical fitness components were captured before, during, after the intervention interval, and at a 10-month follow-up. Positive and negative affect levels and objective cognitive fitness parameters served as possible covariates. Multilevel modeling revealed that the computer group rated memory and concentration as having improved at 4 months and again at 6 months. The exercise group, in contrast, perceived physical capacities as maintained or improved. The characteristics of the activity experience seem to determine the perceived fitness changes. We conclude that actual learning experiences improve one's self-concept of abilities.     

Is the seductive details effect moderated by mood? An eye‐tracking study

According to the seductive details (SD) effect, interesting, but irrelevant information in learning materials reduces learning outcomes. Basic research suggests that subjects in positive mood are more distractible by task‐irrelevant stimuli than subjects in negative mood. Hence, mood could moderate the SD effect. We tested this assumption by comparing eye movements to seductive pictures in participants in positive versus negative mood. As expected, participants in positive mood fixated pictures longer and more frequently than participants in negative mood, which can be interpreted in terms of mood‐based higher distractibility. However, this did not translate to a more pronounced SD effect in the learning test. Unexpectedly, there was no SD effect in either mood condition. We discuss implications of the eye‐tracking data as well as potential reasons for the nonexistent SD effect in our study.
