Recent models of the conceptual system hold that concepts are grounded in simulations of actual experiences with instances of those concepts in sensory-motor systems (e.g., Barsalou, 1999, 2003; Solomon & Barsalou, 2001). Studies supportive of such a viewhave shown that verifying a property of a concept in one modality, and then switching to verify a property of a different concept in a differe...

Switching between tasks that overlap in perceptual and response characteristics is assumed to rely upon the maintenance of task representations in prefrontal cortex (PFC). However, task-switching studies demonstrate ‘‘switch costs,’’ even when there is sufficient time to prepare for a new task. These costs suggest that task-switching performance reflects a complex interplay between priming and ...

When choosing between incompatible technologies that are characterized by network effects in business or consumer markets, e.g., software (Microsoft vs. Open Source) or “Walkie-Talkie” phones (Direct Connect vs. Push to Talk), customers must decide between compatibility with others and individual fit. Given differing customer preferences, we study the adoption dynamics and pricing strategies of...

In four experiments, task-switching processes were investigated with variants of the alternating runs paradigm and the explicit cueing paradigm. The classical diffusion model for binary decisions (Ratcliff, 1978) was used to dissociate different components of task-switching costs. Findings can be reconciled with the view that task-switching processes take place in successive phases as postulate...

Ageing is associated with changes in sleep and decline executive functions, such as task-switching and task preparation. Given that sleep affects executive function, age-related changes in executive function may be attributable to changes in sleep. The present study used a sleep detection device to examine whether or not wake time after sleep onset and total sleep time moderated age differences...

Hybrid optimal control problems are studied for systems where autonomous and controlled state jumps are allowed at the switching instants and in addition to running costs, switching between discrete states incurs costs. A key aspect of the analysis is the relationship between the Hamiltonian and the adjoint process before and after the switching instants as well as the relationship between adjo...

The ability to retain and lock-in customers in the face of competition is a major concern for e-commerce businesses, especially those that invest heavily in advertising and customer acquisition. In this paper, we propose a method for measuring the magnitude of switching costs and brand loyalty for on-line service providers based on the random utility modeling framework. Applying this approach t...

Objectives of the Study The purpose of this thesis is to evaluate the switching costs while adopting a new mobile platform and examine the network effects on the user switching behavior of the mobile platforms. In addition, this thesis examines whether it is more difficult to shift to a new cloud service provider or mobile platform. Windows, Android and iOS are the three platforms that are anal...

Video game expertise has been shown to have beneficial effects for visual attention processes, but the effects of action video game playing on executive functions, such as task switching and filtering out distracting information, are less well understood. In the main experiment presented here, video game players (VGPs) and nonplayers (nVGPs) switched between two tasks of unequal familiarity: a ...

In Norman (2003a), the introduction of individual strategy switching costs, and thus inertia, into stochastic evolutionary coordination games was found inter alia to strengthen the mixed-strategy equilibrium as a shortto medium-run equilibrium. This paper considers the impact of such switching costs on the conflict scenario of HawkDove games. The “attractive” mixed-strategy equilibrium of HawkD...
