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...

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...

Area of Science:

Cognitive Science
Human-Computer Interaction
Neuroscience

Background:

Web navigation is a complex cognitive task involving attention, perception, and memory.
High cognitive load during online activities can lead to stress, anxiety, and mental/physical illnesses.
The COVID-19 pandemic highlighted the need to understand cognitive load in remote work and learning.

Purpose of the Study:

To investigate cognitive load during online comprehension and information-seeking tasks.
To compare cognitive load between mobile and PC-based devices for these tasks.
To provide insights for designing more user-friendly and less cognitively demanding web interactions.

Main Methods:

Electroencephalography (EEG) using a low-cost wireless headset measured cognitive load.
Two tasks were used: online reading comprehension (CO) and online information-seeking (IS).
Participants performed tasks on either mobile (MB) or desktop (PC) devices, with 11 participants per condition.

Main Results:

Baseline (BL) showed the lowest cognitive load.
Information-seeking (IS) tasks resulted in the highest cognitive load, particularly on mobile devices.
Increased brainwave band power (except alpha) indicated higher cognitive load during tasks.

Conclusions:

Cognitive load varies significantly with task type and device used.
Information-seeking on mobile devices imposes a substantial cognitive burden.
Low-cost wearable EEG devices can quantify cognitive load, aiding in web interaction design improvements.
