A multiple secretary problem with switch costs
… selection rule for the secretary problem with switch costs, in which a known number of applicants appear sequentially in a random order, and the objective is to maximize the sum of the qualities of all hired secretaries over all time. It is assumed that the quality of each applicant is …

Task Switching in Predictable and Unpredictable Cases
… the cognitive processes that underlie the switching between simple cognitive tasks. Central to these experiments was the predictability factor; in half of the cases, the upcoming task could be predicted in advance with absolute certainty while in the other half no foreknowledge regarding …

Characterizing Task-Switching Performance in Adults with ADHD
… areas of executive functioning, including task-switching. Individuals with ADHD are typically slower and less accurate when switching between tasks during a cued paradigm. However, Sams et al. (2017) examined task-switching ability in adult ADHD with a more naturalistic voluntary paradigm that …

Controlling memory and resolving interference : prefrontal contributions to flexible behavior
… flexible performance is enabled during task switching. Chapter 1 reviews major findings and controversies in the task switching literature, highlighting (1) evidence that behavioral switch costs may derive from proactive interference due to the facilitated retrieval of irrelevant competitors …

Inhibitory control mechanisms and their role in task switching: A multi-methodological approach
… control allows us to ignore distraction and switch between tasks in a flexible, yet organized fashion. While a hallmark of controlled behavior, distinctions among executive control processes are not thoroughly agreed upon. The present work explored the organization of two of these executive …

When do dialects become languages? A cognitive perspective
… of dialects using an adaptation of a Language Switching Paradigm to determine if the effort required to switch between dialects is similar to the effort required to switch between languages. The results closely replicated what is typically shown for bilinguals: Bidialectal speakers exhibited a …

The dissipating task-repetition benefit in cued task-switching : exploring the role of task-set decay vs.temporal distinctiveness in episodic task retrieval
… flexible adaptations of behavior. The task-switching paradigm allows to study cognitive control processes when switching between two different tasks with unpredictable order. The basic idea assumes that contrary to well practiced tasks, switching between unpracticed, poorly structured, or …

Cognitive flexibility and fronto-parietal control dynamics in aging
… in middle-to-older aged adults using a cued task-switching paradigm. Older adults show a specific decline in fronto-parietal regions and in executive function abilities, particularly in tasks that involve flexibly allocating attention. Here, in addition to age, corpus callosum and modulation over …

Handlungsdeterminierende Prozesse beim Aufgabenwechsel und die Notwendigkeit der Dekomposition von Wechselkosten
In dieser Arbeit werden handlungsdeterminierende Prozesse beim Aufgabenwechsel untersucht. Die ersten durchgeführten Experimente zeigten, dass es notwendig ist, Wechselkosten in verschiedene Teile zu zerlegen, so dass die Dekomposition von Wechselkosten einen großen Teil des Empirieteils ausmacht. …

Effects of acute alcohol intoxication on visual processing and oculomotor control
… The two complex visual cognitive tasks were task switching and reading. Task switching requires participants to switch between two or more distinct tasks, which usually results in switch costs or benefits. Such effects are explained with the interplay of inhibition and activation and to date no …
