Children who have complex communication needs can benefit from the use of a speech-generating device (SGD). Cognitive skills were identified as having an impact on the ability to navigate between levels of SGDs. This protocol describes the steps needed for Speech-language Pathologists to assess cognitive skills and navigational abilities.

Monitoring brain activity outside the lab without physical constraints presents methodological challenges. A fiberless, wearable functional Near Infrared Spectroscopy (fNIRS) system was used to measure brain activity during an ecological prospective memory task. It was demonstrated that this system could be used to monitor brain activity during non-lab based experiments.

This protocol describes the use of physiological indicators to measure variations in cognitive load across different task difficulty levels in human-AI collaborative tasks. The findings suggest that people adapt their decision-making processes according to task difficulty, thereby reflecting different levels of cognitive load.

The emotional Stroop effect (ESE) is the result of longer naming latencies to ink colors of emotion words than those of neutral words. This report refers to potential sources of confounding and includes a modal experiment that provides the means to control for them.
FAQs
Reliable cognitive-task results depend on controlling the stimulus, instructions, and testing conditions. Standardization limits variation unrelated to the mental process under study, making differences in accuracy, reaction time, or task-related brain activity easier to interpret. This design principle is especially important when researchers compare people across development, aging, learning, treatment, or neurological-disorder studies.
Accuracy and reaction time provide complementary behavioral measures. Accuracy indicates how often responses match the task requirement, whereas reaction time captures response speed. Researchers can examine these outcomes alongside task-related changes in brain activity to relate observable performance to underlying neural systems. Considering both measures helps avoid treating a single behavioral result as the complete account of task performance.
Selecting a task that matches the target process is central to interpretation. A perception task, attention task, memory task, language task, or decision-making task directs measurement toward a different aspect of cognition through its stimuli and instructions. This alignment lets researchers ask more focused questions about which mental process is associated with observed behavior or neural activity.
A typical study presents participants with controlled stimuli or instructions, records their responses, and then analyzes performance measures such as accuracy and reaction time. Researchers may also examine task-related changes in brain activity during the same activity. Keeping presentation and testing conditions consistent allows the resulting behavioral and neural measurements to be compared more meaningfully.
Cognitive tasks are used to examine change across development and aging, assess effects associated with learning or treatment, and investigate neurological disorders. In each setting, researchers can compare task performance and related brain activity to characterize differences or changes in cognitive function. The approach therefore supports both basic studies of brain function and evaluations of clinically relevant outcomes.
Researchers connect task performance with neural systems by examining behavioral responses together with task-related changes in brain activity. A pattern in accuracy or reaction time can be considered alongside corresponding neural measurements, rather than interpreted in isolation. This combined view helps neuroscience studies relate what a participant does during the task to brain function associated with that performance.
