Purposive Learning

Purposive 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...

Cognitive Learning

Cognitive Learning

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.
Tolman introduced the idea that behavior is influenced by...

Associative Learning

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Introduction to Learning

Introduction to Learning

Learning is the process of acquiring knowledge or skills through practice or experience, leading to long-lasting behavioral changes. This acquisition occurs through interaction with the environment and requires practice or experience. For instance, mastering a skill such as surfing requires considerable practice and experience, highlighting the essential role of repeated interactions with the environment in learning.
In contrast to learned behaviors, unlearned behaviors such as crying, sexual...

Higher Mental Functions of Brain: Learning and Memory

Higher Mental Functions of Brain: Learning and Memory

Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Observational Learning

Observational Learning

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...

Area of Science:

Radiology
Artificial Intelligence
Medical Education

Background:

Radiologists interpret medical images, a skill that can be enhanced.
Artificial intelligence (AI) shows promise in medical image analysis.
Teaching tools are crucial for improving diagnostic accuracy.

Purpose of the Study:

To evaluate if a deep learning (DL) model can serve as a teaching tool.
To determine if radiologists' imaging task performance improves without direct AI assistance post-training.
To assess the impact of AI-derived interpretation maps on radiologist accuracy.

Main Methods:

Three radiologists reviewed DL model outputs, including "heat maps," for 50 knee radiographs.
Radiologists' ability to determine patient sex from knee radiographs was tested before and after AI tool exposure.
A second set of 50 radiographs was used for post-training assessment two weeks later.

Main Results:

Initial radiologist accuracy in sex categorization was 0.59, not significantly better than chance.
The DL model achieved 0.96 accuracy in sex categorization.
Post-training, radiologist accuracy significantly improved to 0.80 (p=0.0270) without concurrent AI use.

Conclusions:

AI-derived data, specifically interpretation maps, can effectively teach radiologists.
Radiologists' intrinsic accuracy in imaging tasks can be improved using AI as a teaching aid.
This study introduces a novel method for AI-assisted radiologist education in the radiology literature.
