An Introduction to Learning and Memory
0 Views •
2023
Learning is the process of acquiring new information and memory is the retention or storage of that information. Different types of learning, such as non-associative and associative learning, and different types of memory, such as long-term and short-term memory, have been associated with human behaviors. Studying these components in detail helps behavioral scientists understand the neural mechanisms behind these two complex phenomena. JoVE's overview on learning and memory introduces common...

Visual Statistical Learning

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University The visual environment contains massive amounts of information involving the relations between objects in space and time; certain objects are more likely to appear in the vicinity of other objects. Learning these regularities can support a wide array of visual processing, including object recognition. Unsurprisingly, then, humans appear to learn these regularities automatically, quickly, and without conscious awareness. The name...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Colloquially, the terms learning and memory encompass a broad range of behaviors and mental systems, everything from learning to tie a shoe to mastering calculus (and a lot in between). Experimental psychologists have divided up learning mechanisms into groups that seem to have different properties, and that seem to rely on different brain systems. A major division is between declarative and non-declarative memory, roughly, the...

Avoidance Learning and Learned Helplessness
0 Views •
2024
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli. Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
FAQs
A Learning Index is derived by comparing performance at different points in repeated-task testing. The study may quantify improvement through accuracy, response latency, or errors, then express the change as a comparable value. The calculation therefore depends on which behavioral outcome the design emphasizes, allowing learning rate or task acquisition to be evaluated consistently within that experiment.
The chosen performance measure determines what aspect of acquisition the index emphasizes. Accuracy can represent correct responding, response latency can capture speed, and errors can indicate unsuccessful performance. Retention provides a separate view of whether performance persists. Selecting among these outcomes should match the experimental question, because each measure summarizes a different behavioral change.
Comparing Learning Index values between experimental groups is useful because it converts trial-related performance changes into a common basis for examining differences. The same logic can be applied to contrasts involving brain regions, neural manipulations, or disease models. Such comparisons help determine whether an experimental condition is associated with altered learning rate, task acquisition, or memory persistence.
A high or low value should be interpreted in relation to the outcome and study design rather than in isolation. An index based on accuracy does not summarize exactly the same behavioral feature as one based on response latency or errors. Stating the measure and comparison used is therefore essential when relating the value to learning or memory.
To construct the measure, researchers first repeat the task or association across trials, record the selected behavioral outcome, and compare performance as acquisition proceeds. They then convert the observed change into a quantitative value suited to the study design. This workflow produces a summary that can be examined within an individual or used for comparisons across experimental conditions.
In neuroscience, the measure links behavioral change with questions about underlying neural mechanisms. Researchers can compare indices across brain regions, after neural manipulations, or in disease models, then relate differences in performance change to learning and memory processes. It supplies a behavioral outcome against which neural observations can be considered, helping connect experimental brain changes with task performance.
