Assessing Dexterity with Reaching Tasks
0 Views •
2023
Reaching tasks are employed in behavioral neuroscience to investigate motor learning and forelimb dexterity. Much like human hands, rodents have dexterous forepaws, which are necessary for executing coordinated and precise motor movements. Experimenters may utilize food rewards to train rodents to reach and for testing their reaching abilities. These tasks help behavioral neuroscientist in understanding how CNS injuries, such as a stroke, may impair reaching ability and dexterity in humans.

The 5-Choice Serial Reaction Time Task: A Task of Attention and Impulse Control for Rodents
0 Views •
Cited by 59 •
2014
This protocol describes the 5-choice serial reaction time task, which is an operant based task used to study attention and impulse control in rodents. Test day challenges, which are modifications of the standard task, increase flexibility of the task and can be combined with other manipulations to more fully characterize behavior.

Piaget's Conservation Task and the Influence of Task Demands

Source: Laboratories of Judith Danovitch and Nicholaus Noles—University of Louisville Jean Piaget was a pioneer in the field of developmental psychology, and his theory of cognitive development is one of the most well-known psychological theories. At the heart of Piaget’s theory is the idea that children’s ways of thinking change over the course of childhood. Piaget provided evidence for these changes by comparing how children of different ages responded to questions and problems that he...

Learning and Memory: The Remember-Know Task
0 Views •
2023
Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Our experience of memory is varied and complex. Sometimes we remember events in vivid detail, while other times we may only have a vague sense of familiarity. Memory researchers have made a distinction between memories that are recollected versus those that are familiar. A recollected item is one that is not only remembered, but carries with it details of the time at which it was learned or encoded.
FAQs
Recall and recognition trials place different demands on access to learned information. Recall requires participants to recover information, whereas recognition asks them to evaluate previously learned information when it is presented as part of the trial. Comparing accuracy, response time, or confidence across these formats helps researchers determine how the form of retrieval affects observed memory performance.
These measures capture complementary aspects of retrieval. Accuracy indicates whether the participant accessed the learned information correctly, response time shows how quickly performance occurred, and confidence reflects the participant’s certainty in that judgment. Examining them together helps separate successful memory access from differences in speed or subjective evaluation, rather than relying on a single outcome.
A retrieval task can compare memory performance with response characteristics to identify whether an outcome reflects access to stored information or the later decision about that information. Accuracy, response time, and confidence provide separate behavioral signals, while neural recordings relate those signals to brain activity. This combination helps researchers interpret retrieval without treating every response difference as a memory difference.
The procedure begins with participants learning information, followed by recall or recognition trials in which cues prompt access to that material. Researchers record responses such as accuracy, response time, and confidence, and may collect neural recordings during performance. These measurements are then related to the task phase and behavioral outcome to study the neural basis of memory access.
Retrieval tasks are especially useful for examining the contributions of the hippocampus and prefrontal regions. By relating neural recordings to successful or less successful performance, researchers can study how these areas participate in accessing learned information. The design also helps connect regional brain activity with measurable behavior rather than interpreting neural signals independently of memory outcomes.
Researchers apply retrieval tasks to study learning strategies, memory disorders, aging, and neurological injury. The same behavioral measures can reveal differences in accuracy, speed, or confidence across individuals or conditions, while neural recordings provide corresponding brain-activity information. This makes the paradigm useful for comparing how memory access changes across populations and experimental circumstances.
