While decades of research have deepened our understanding of time perception, the perception of (manipulated) video speed has been relatively underexplored but is gaining interest with recent technological advances. This study systematically investigated human perception of "video speed," "clip duration" and "original…

It is well established that performing multiple tasks simultaneously (dual-tasking) or sequentially (task-switching) degrades performance on one or both tasks. However, it is unknown whether task-switching adds to the effects of dual-tasking in a single setup. We investigated this in a simulated everyday-like car driving scenario. We expected an…

Individuals often have difficulties completing tasks in a timely manner. Whether it be scheduling a doctor's appointment, purchasing a birthday gift, or booking an airline ticket, waiting until the very last minute can carry serious consequences. In two experimental studies, we explore how individuals can be encouraged to finish tasks promptly. We…

Multitasking abilities are vital for conducting flight missions. Traditional theories of multitasking suggest that cognitive resources represent a determining factor of said performance. The current study takes a different approach by investigating how the stability-flexibility-dilemma of cognitive control influences multitasking performance in a…

We report results from two experiments that examined the time course of vigilance decrements during a demanding multitasking scenario. Specifically, we implemented a novel paradigm in two experiments in which a total of 123 participants performed a go-no-go target detection continuous performance test (CPT) task simultaneously with a driving-based…

Although humans often multitask, little is known about how the processing of concurrent tasks is managed. The present study investigated whether adjustments in parallel processing during multitasking are local (task-specific) or global (task-unspecific). In three experiments, participants performed one of three tasks: a primary task or, if this…

The pervasive nature of media multitasking in the last fifteen years has sparked extensive research, revealing a nuanced but predominantly negative association with executive function. Given the cognitive demands and technological landscape of the modern battlefield, there is a critical interest in understanding how these findings may or may not…

Previous studies have provided evidence that introspection about dual-task performance in the psychological refractory period (PRP) paradigm is severely limited. The present study investigated introspection at the other pole of the multitasking continuum, namely task switching. In 2 experiments, participants provided estimates of their response…

The risk of multitasking is high in online surveys. However, knowledge on the effects of multitasking on answer quality is sparse and based on suboptimal approaches. Research reports inconclusive results concerning the consequences of multitasking on task performance. However, studies suggest that especially sequential-multitasking activities are…

There is mounting empirical evidence to suggest that adults are intuitively cooperative. When presented with a cooperative dilemma between self-maximizing and benefitting the common good, decisions made quickly are more likely to be cooperative, whereas slow decisions tend to favor self-interest. To investigate the ontogenetic origins of intuitive…

Task understanding is theorized as a critical aspect of effective learning, but its role in self-regulated learning and overall academic performance has been understudied. Research to date indicates that students with adequate task understanding perform well. However, these studies have not demonstrated what practices are needed for developing…

Visual inspection of luggage using X-ray technology at airports is a time-sensitive task that is often supported by automated systems to increase performance and reduce workload. The present study evaluated how time pressure and automation support influence visual search behavior and performance in a simulated luggage screening task. Moreover, we…

The widespread adoption of mobile technologies has exacerbated their utilization in educational environments. Multitasking in the classroom is a common practice and deserves further investigation to understand its antecedents. Yet, rare studies have addressed this issue based on the theory of planned behavior framework. To this end, the current…

Multitasking has been demonstrated to negatively impact performance across a wide range of tasks, including in the classroom, yet students continue to multitask. This study examined the relationship between college students' perceptions and performance of technology-based multitasking. Technology-based multitasking and self-efficacy data were…

Background: 'Snack writing' is a term coined to describe regular short bursts of writing on a larger academic writing task. There is extensive research on academic writing, but research on 'snack writing' is limited. Moreover, the idea of 'snack writing' in an online environment is not evident in the literature. Objectives: The study objectives…
