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...

Prediction Intervals

Prediction Intervals

The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Introduction to Cognitive Psychology

Introduction to Cognitive Psychology

Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Cognitivism

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

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...

Area of Science:

Computational cognitive science
Machine learning
Educational technology

Background:

Machine learning (ML) and cognitive science offer complementary computational approaches to modeling human behavior, but cross-disciplinary integration is limited.
E-learning and knowledge acquisition present a unique intersection where ML and cognitive science methodologies can be integrated for personalized learning tools.
Accurate tracking of learning and forgetting, and predicting future performance are crucial for effective e-learning.

Purpose of the Study:

To enhance a state-of-the-art ML model by integrating insights from a cognitive model of human memory.
To investigate the utility of the predictive performance equation (PPE) for engineering input features in ML models for e-learning.
To demonstrate the benefits of combining cognitive and ML approaches, particularly when data is high-dimensional but limited.

Main Methods:

Engineered timing-related input features for a gradient-boosted decision trees (GBDT) model using the predictive performance equation (PPE).
Incorporated domain knowledge from a cognitive model of human memory into an ML framework.
Compared the performance of the PPE-enhanced GBDT model against a default GBDT model.

Main Results:

The PPE-enhanced GBDT model demonstrated superior predictive performance compared to the default GBDT model.
The enhancement was particularly evident under conditions with limited training data.
Cognitive model insights significantly improved ML model predictions even when applied to only one aspect of the data.

Conclusions:

Integrating cognitive and ML models offers a promising approach for developing effective personalized learning tools.
This hybrid approach is particularly beneficial for high-dimensional datasets that are insufficient for training complex ML algorithms alone.
Cognitive insights can effectively 'jump-start' ML model performance, paving the way for future interdisciplinary research.
