The effect of different distractions on remembering delayed intentions

In safety-critical domains, frequently intentions need to be delayed until an ongoing task is completed. Research using the delay-execute paradigm showed that interruptions during the delay cause forgetting. However, staff members often handle an initial distraction not by interrupting the ongoing task but by acknowledging the distraction or multitasking. In Experiments 1a and 1b, we observed that, compared to a no distraction condition, multitasking significantly decreased remembering of intentions and interrupting decreased remembering even further. In Experiment 2, interruptions with context change reduced remembering of intentions compared to uninterrupted delays, and at the same time, interruptions without context change improved memory performance compared to uninterrupted delays. However, improved memory performance resulted in decreased interrupting task performance. Theoretically, the results support the contextual cueing mechanism of delay-execute tasks. Considering safety-critical domains, multitasking, interruptions and context changes can contribute to forgetting of tasks.     

Just more of the same,or different? An integrative theoretical framework for the study of cumulative interruptions at work

We propose a theoretical framework that explores the accumulation of work interruptions and their effects. Most research studies have dealt with interruptions as isolated phenomena, ignoring the simultaneous or sequential occurrence of interruptions common in everyday life. We fill this gap and provide insight into the process of the accumulation of interruptions by mapping deep-level regulation onto an observable sequence of actions. Furthermore, we explain how cumulative interruptions can lead to qualitatively different effects because of the interaction and joint development of isolated effects, identifying some mediating and moderating factors. In doing so, we disclose the relationships between the effects of single interruptions found in laboratory studies and the impacts on health and well-being of multiple interruptions found in applied research.     

人机互动中的任务中断：新环境中的新问题

任务中断是“R-V”居间系统（“现实-虚拟”居间系统）中的人机互动所要频繁面临和处理的一种现象。任务中断对主任务执行的影响主要有三种情况：消极的、积极的和因情况而异的。对中断延迟期间心理作用机制的研究揭示了中断延迟期间的准备是如何对主任务恢复发生作用的,主要理论包括：任务转换理论,长时工作记忆理论,目标记忆理论和线程认知理论。任务转换理论为中断延迟作用机制的研究提供了基础的模式,目标记忆理论和长时工作记忆理论各自提出了复述和编码两种不同的观点,线程认知理论主张多线程并行,深化了任务中断的研究。未来的研究应关注于研究中断对主任务执行产生不同影响的原因、影响中断任务执行期间复述机会的因素以及中断延迟期间的准备是对信息的复述还是编码。对任务中断理论的综述意义在于使未来有关任务中断的研究更加深入且具有实践意义。     

Researching mind wandering from a first‐person perspective

Mind wandering is an inherently inner (or first‐person) phenomenon that leaves few direct traces for third‐person enquiry. Nonetheless, psychologists often study mind wandering using third‐person (e.g., behavioral or neuronal) research methods. And although research–participants may well be asked to introspect on their mind wandering experiences (e.g., via experience‐sampling or think‐aloud techniques), such introspective self‐observations typically lack methodological rigor and are hence of only preliminary value. Here, we argue that it is a missed opportunity to not train researchers to introspect on their own mind‐wandering experiences to better understand the associated mental processes. We propose a novel approach to cultivating an educated form of introspection in the study of attentional focusing and mind wandering. Our research adds to the current theoretical understanding by explicating conditions that facilitate mind wandering (e.g., the shifting and broadening of concepts) and help find the way back to the primary task (e.g., commitment; deliberate shifts between focusing and defocusing).     

How do cynical employees serve their customers? A multi-method study

In this multi-method study, we investigate how social job demands (i.e., social interruptions) and resources (i.e., colleague support) in the service context influence employee (negative) (re)actions to customers through cynicism towards the job. In addition, we investigate why customers are less satisfied with the provided service when employees endorse a cynical attitude. To test the hypothesized process, we used observer ratings of the employee–customer interactions regarding the number of interruptions and employee negative (re)actions during service encounters, employee self-reports of overall colleague support and daily cynicism, and customer-ratings of service quality. Participants were 48 service employees and 141 customers. Results of multi-level structural equation modelling analyses showed that whereas the number of observed social interruptions during service encounters related positively to cynicism, social support related negatively. Cynical employees exhibited more negative (re)actions towards their customers (e.g., expressed tension, were unfriendly). Consequently, the more negative (re)actions employees showed towards their customers, the less satisfied customers were with the service quality. The study contributes to the literature by explaining what makes service employees cynical about their work, and why cynical employees provide low-quality services.     

Selective attention as a protagonist in contemporary workplace stress: implications for the interruption age

Background and Objectives: The ubiquity of instant messages and email notifications in contemporary work environments has opened a Pandora's Box. This box is filled with countless interruptions coming from laptops, smartphones, and other devices, all of which constantly call for employees’ attention. In this interruption era, workplace stress is a pervasive problem. To examine this problem, the present study hypothesizes that the three-way interaction among the frequency with which interrupting stimuli appear, their salience, and employees’ deficits in inhibiting attentional responses to them impacts mental workload perceptions, ultimately leading to stress. The study, further, probes a related form of self-efficacy as a potential suppressor of interruption-based stress. Design: The study used a 2 (low vs. high frequency) × 2 (low vs. high salience) mixed model design. Methods: The 128 subjects completed a test of their inhibitory deficits and rated their mental workload perceptions and experiences of stress following a computer-based task. Results: Inhibitory deficits and increased interruption salience can alter the perception of mental workload in contemporary work environments for the worse, but interruption self-efficacy can help offset any resulting interruption-based stress. Conclusions: This study extends the literatures on work interruptions as well as on stress and coping in the workplace.
