Task Interruption and Resumption Paradigm for Testing the Activation and Pursuit of an Abstract Thinking Goal
0 Views •
2017
This protocol was designed to test the activation and pursuit of cognitive goals (e.g., an abstract thinking goal) using the task interruption and resumption paradigm. The protocol is suitable for cognitive goals that are automatically pursued once activated, as the distraction procedure prevents goal pursuit during the interruption period.

2015
A novel cognitive paradigm is developed to elucidate behavioral and neural correlates of interference by to-be-ignored distractors versus interference by to-be-attended interruptors during a working memory task. In this manuscript, several variants of this paradigm are detailed, and data obtained with this paradigm in younger/older adult participants is reviewed.

Here, we describe a technique, protein film infrared electrochemistry, which allows immobilized redox proteins to be studied spectroscopically under direct electrochemical control at a carbon electrode. Infrared spectra of a single protein sample can be recorded at a range of applied potentials and under a variety of solution conditions.

FAQs
Changing the applied potential can alter or stop electron transfer, which changes whether catalytic turnover continues. Restarting at a defined potential allows researchers to compare the reaction before and after the interruption. This controlled change helps identify which parts of the pathway depend directly on electrochemical driving force and which can proceed through later chemical steps.
A pause in electron transfer separates the electrochemical event from reactions that may follow it without continued electrical input. Researchers can examine what changes during the interruption and after the potential or current is restored. Differences between these stages help determine whether an observed transformation requires electron transfer or occurs as a subsequent chemical process.
Interrupting turnover can provide a time window in which short-lived intermediates may influence the observed reaction pathway before catalysis resumes. Studying these pathway stages helps explain how products form and why selectivity changes. The same approach also reveals whether the catalyst returns to its prior activity, providing information about stability and recovery.
Researchers first allow the electrochemical catalytic reaction to proceed, then deliberately change the applied potential or current, stop electron transfer, or remove the driving force. They observe the altered state before restarting under defined conditions. Comparing reaction behavior across the uninterrupted, paused, and restarted stages supports pathway analysis and evaluation of catalyst recovery.
In electrosynthesis, the strategy can clarify how electrical input controls product formation and selectivity. Pausing or modifying turnover lets researchers examine pathway stages rather than treating the reaction as a continuous sequence. Those observations can guide adjustments to catalytic conditions and support the design of systems that produce desired products more selectively.
Energy-conversion studies can use controlled interruption to examine how a catalyst responds when its electrochemical driving force changes or disappears. Restarting the reaction tests whether activity is recovered under defined conditions. These observations provide mechanistic and stability information that can guide the development of more efficient catalytic systems for electrochemical processes.
