Summary
Children with attention-deficit/hyperactivity disorder (ADHD) showed learning differences on a reinforcement learning task. Their difficulties may stem from increased exploration or inconsistent choices, not just learning deficits.
Area of Science:
- Neuroscience
- Developmental Psychology
- Cognitive Science
Background:
- Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder impacting executive functions.
- Reinforcement learning theories offer potential explanations for ADHD's cognitive symptoms.
Purpose of the Study:
- To evaluate prominent reinforcement learning theories of ADHD.
- To investigate learning and decision-making processes in children with ADHD.
Main Methods:
- Children with ADHD and controls completed a reinforcement learning task.
- Performance was analyzed across learning and extinction phases.
Main Results:
- Children with ADHD required more trials to meet learning criteria.
- They exhibited reduced target selection during extinction.
- Performance differences were linked to exploration or choice consistency, not solely learning deficits.
Conclusions:
- Findings partially support existing reinforcement learning theories of ADHD.
- ADHD-related performance deficits on these tasks may involve altered exploration or decision-making strategies.

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

1.8K
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...

Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

02:30Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
