The Attentional Demand of Automobile Driving Revisited: Occlusion Distance as a Function of Task- Relevant Event Density in Realistic Driving Scenari…
2014
Objective: We studied the utility of occlusion distance as a function of task-relevant event density in realistic traffic scenarios with self-controlled speed. Background: The visual occlusion technique is an established method for assessing visual demands of driving. However, occlusion time is not a highly informative measure of environmental task-relevant event density in self-paced driving scenarios because it partials out the effects of changes in driving speed. Method: Self-determined occlusion times and distances of 97 drivers with varying backgrounds were analyzed in driving scenarios simulating real Finnish suburban and highway traffic environments with self-determined vehicle speed…
Simulation Assessment of Cognitive Readiness
2013
Simulation-based scenarios are used in different approaches for research on complex problem-solving processes. The micro-world approach in this respect has become well known. Despite its attractiveness, there still are concerns about the validity that can be achieved in measuring cognitive functions by means of this method. The chapter refers to an alternative. Quasi-experimental simulations are applied to indicate the individual’s underlying capacity to function in complex, dynamic scenarios. Typically participants get deeply involved in the defined task, resulting in high motivation. The participants’ responses, within the ongoing events, mirror their performance in real-world tasks which…
Harder, Better, Faster, Stronger? The Relationship between Cognitive Task Demands in Video Games and Recovery Experiences
2019
Research has repeatedly demonstrated that the use of interactive media is associated with recovery experiences, suggesting that engaging with media can help people to alleviate stress and restore mental and physical resources. Video games, in particular, have been shown to fulfil various aspects of recovery, not least due to their ability to elicit feelings of mastery and control. However, little is known about the role of cognitive task demand (i.e., the amount of cognitive effort a task requires) in that process. Toward this end, our study aimed to investigate how cognitive task demand during gameplay affects users’ recovery experiences. Results of a laboratory experiment suggest that dif…

视觉工作记忆存储的表征单位 [The Representation Unit of Visual Working Memory]
2022
The visual working memory is a limited storage system in which people could flexibly process the representations to complete the task. Among studies on the capacity of visual working memory, the representation unit is a prior subject. Previous research employs the change-detection paradigm and the recall paradigm to explore the nature of representations when features of diverse dimensions and different-level features of the same dimension are stored in the visual working memory. These studies elicit two binary hypotheses: the object-based representation hypothesis backs that those diverse features are bound on the object and form a whole, while the feature-based representation hypothesis su…
