Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual mental imagery refers to the ability to conjure images in one’s mind’s eye. This allows people to process visual material above and beyond the constraints of a current point-of-view; for example, a person could imagine, using their mind’s eye, how something might look in a different color, or what it would look like if it were made from a different material or rotated and seen from a different perspective. Mental imagery...

Source: Carmen Black, Matthew Goldenberg, and Jaideep Talwalkar; Yale School of Medicine The mental status exam is a clinical evaluation of emotional, perceptual, and cognitive functioning that spans both the fields of psychiatry and neurology. Developing skill in the psychiatric portions of the examination are important to describe salient aspects of the patient's mental state that may be observed during routine history and/or physical exam. Proficiency in the cognitive portions of this...

Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms. Individuals with depression often experience challenges in both their personal and professional...

Robert M Rioux, Ajay Sathe, Zhifeng Chen, Pennsylvania State University, University Park, PA A glovebox is an isolated enclosure that is designed to maintain an inert atmosphere. The manipulation of chemicals or apparatus is done via the use of gloves, which allow operation while still maintaining an inert atmosphere. A positive pressure is utilized to compensate for any passive leaks. Objects can be transferred in and out of the box using an antechamber that acts as an airlock between the box...
FAQs
Researchers design conditions in which a target operation is required while competing mental activities are controlled or minimized. They then compare responses across those conditions. Differences in performance provide evidence about the target process’s contribution, helping distinguish whether behavior reflects attention, memory retrieval, decision-making, mental transformation, or another operation.
Comparison conditions provide a reference for interpreting behavioral differences. If one condition adds or emphasizes a particular operation while other demands remain controlled, changes in responses can be linked more plausibly to that operation. This comparison-based logic supports more precise conclusions about how cognition is organized rather than treating performance as the product of one undifferentiated mental activity.
Broad tasks may require several mental activities at once, making it difficult to determine which process produced a given response. Mental Operation Isolation narrows the task demands and limits competing operations, allowing researchers to examine a more specific contribution. This approach can therefore produce clearer evidence for models that represent thinking as organized into distinct cognitive operations.
The approach can target operations such as attention, memory retrieval, decision-making, and mental transformation. The selected operation determines the task demands and the competing activities that must be controlled. Studying these different operations separately helps researchers compare their roles in behavior and investigate how distinct forms of cognition contribute to learning, reasoning, and problem-solving.
A study begins by selecting the cognitive operation of interest and designing a task that directly requires it. Researchers then control or minimize other mental activities that could influence performance, create comparison conditions, and examine responses across those conditions. The resulting pattern is used to evaluate the selected operation’s role in behavior and refine cognitive models.
It is useful when researchers need to separate contributions to performance in learning, reasoning, or problem-solving. The approach also supports studies of cognitive change across development and investigations of changes associated with neurological conditions. By focusing analysis on specific operations, it can help explain why performance differs across people, conditions, or stages of cognitive change.
