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.

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...

Marginal Dishonesty: The Adding-to-10 Task

Source: Julian Wills & Jay Van Bavel—New York University Classical economic theory asserts that people are rational and self-interested. In addition to seeking wealth and status, people are motivated by other goals. As a result, financial motives can sometimes be dwarfed by other internal needs, such as maintaining a positive self-concept or affiliating with other group members. Ethical dilemmas, such as the temptation to cheat on taxes, can result when these motives are in conflict. On...

In Vitro Recording of Theta Oscillations in the Mouse Hippocampus

2025
This video demonstrates the recording of rhythmic neuronal network activity, also known as theta oscillations, in an isolated hippocampus. Electrodes are inserted into various layers and spatial positions to detect and analyze theta oscillations. This shows the unique neuronal compositions and the connectivity of the neuronal network across different layers of the hippocampus.

Decision-making and the Iowa Gambling Task

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Decision-making is an important component of human executive function, in which a choice about a course of action or cognition is made from many possibilities. Damage to the inferior parts of the frontal lobes can affect a person's ability to make good decisions. However, while decision-making deficits can have a large impact on one's life, these deficits can be difficult to quantify in the laboratory.
FAQs
These tasks require an individual to encode relationships among events, locations, or environmental cues rather than produce a straightforward sensory or motor response. That distinction helps researchers interpret poor performance as a possible memory-related impairment, especially when simpler sensory or motor abilities remain relatively preserved. The design therefore links behavioral success to relational representation and later retrieval.
Performance reflects several stages of memory processing. Information must first be encoded, then consolidated into a more lasting representation, and later retrieved when the behavioral test requires it. A disruption at any of these stages can reduce task performance, so researchers can use the timing and pattern of impairment to examine how hippocampal function contributes to memory across the learning process.
The most informative representations involve relationships between events, spatial locations, and environmental contexts. A task may therefore reveal whether an animal or other model can organize relevant cues into a coherent memory representation and retrieve it later. This makes the approach useful for examining how hippocampal activity supports different forms of cognition rather than a single isolated response.
Researchers select a task according to the representation they want to examine, such as relationships among locations, events, or contextual cues. They then interpret performance alongside simpler sensory or motor abilities, because those abilities may remain intact when hippocampal memory is disrupted. This comparison helps distinguish a memory-specific effect from a general inability to perceive, move, or respond.
These tests allow investigators to assess memory, examine the neural circuits and plasticity associated with learning, and evaluate cognitive changes across experimental conditions. They are also used to study how aging, neurological disease, stress, or experimental treatments affect behavior. Because performance depends on retaining and retrieving task-relevant representations, the results connect observable behavior with underlying memory processes.
Reduced performance can indicate disruption of hippocampus-related learning or memory, particularly when simpler sensory or motor responses are spared. Comparisons across rodents and other model systems, or across conditions involving aging, disease, stress, or treatment, can show how these factors influence cognition. The outcome is therefore interpreted as evidence about memory-related function rather than as a standalone measure of general behavior.
