Working memory and cognitive science — from foundational models to everyday applications. Articles are organized from theory to practice.
Working Memory Fundamentals
What Is Working Memory? The Cognitive Engine Behind Thought
Baddeley's multi-component model, the phonological loop, visuospatial sketchpad, and why working memory is the workspace of the mind.
The Phonological Loop — How Your Brain Rehearses Sound
The two-component structure of the phonological loop, the word length effect, phonological similarity, and its role in digit span tasks.
The Visuospatial Sketchpad — Mental Images and Spatial Thinking
The working memory subsystem for visual and spatial information — mental rotation, independence from the phonological loop, and everyday demands.
Working Memory Capacity — Why People Differ and What Affects It
Miller's 7 ± 2, Cowan's four chunks, what chunking actually means, individual differences, and factors that temporarily reduce functional capacity.
Executive Function
Working Memory and Executive Function — How They Connect
The central executive as the bridge between two frameworks — why working memory and executive function are related but not the same thing.
The Three Executive Functions — Updating, Inhibition, and Shifting
Miyake's unity and diversity framework: what updating, inhibition, and shifting each do, how they differ, and what they share.
Inhibition Training: The Cognitive Skill of Ignoring the Wrong Things
What cognitive inhibition is, the Stroop effect, proactive interference, and why filtering is a distinct skill from span capacity.
Cognitive Flexibility — The Science of Shifting Mental Sets
Task switching costs, the difference between switch costs and mixing costs, and why mental sets resist release.
The Common Executive Function — The Engine Behind Self-Control
The shared cognitive factor underlying updating, inhibition, and shifting — what it represents and its relationship to self-regulation.
Training & Tasks
Digit Span Task Explained: Method and What Your Score Means
Forward, backward, and ascending variants — what each measures, typical score ranges, and the methodological reasons digits are used.
Ascending Digit Span: Sorting Under Cognitive Load
How ascending digit span differs from forward and backward span, what cognitive processes sorting engages, and why it is a distinct executive function challenge.
Dual-Task Training: Why Two Tasks Are Harder Than One
Central executive interference, cognitive bottlenecks, and why within-resource competition creates a uniquely demanding training stimulus.
Digit Span and Inhibitory Control — When Some Digits Must Be Excluded
How adding an exclusion rule to forward digit span converts a retention task into an inhibitory control task — and why intrusion errors tell a different story than forgetting.
Compound Cognitive Tasks: Working Memory Under Multiple Executive Demands
Miyake's three executive functions — updating, inhibition, shifting — and why compound tasks mirror the demands of real-world cognition.
Working Memory Training: What the Science Actually Says
The near transfer finding, the far transfer debate, and what this site does and doesn't claim about practicing working memory tasks.
Working Memory in Daily Life
Working Memory at Work — Focus, Switching, and Cognitive Demands
How working memory supports knowledge work — task switching costs, multitasking limits, meetings, and why interruptions are expensive.
Working Memory and Learning — What Research Tells Us
How working memory acts as the gateway to long-term memory, cognitive load theory, and what this means for reading, arithmetic, and instruction design.
Working Memory in Conversation — Why Some Discussions Feel Exhausting
How working memory is involved in following conversations, tracking who said what, understanding complex sentences, and why some discussions are more cognitively demanding.
Cognitive Overload — When the Workspace Gets Too Full
What cognitive overload is, how it accumulates, what it looks like in practice, and how to reduce the likelihood of reaching it.
Working Memory and Age — How Capacity Changes Across the Lifespan
Development in childhood, peak capacity in young adulthood, and the gradual shifts that research associates with aging — and what changes versus what does not.
Working Memory and Sleep — Why Rest Matters for Cognitive Performance
How sleep deprivation impairs working memory, why chronic partial sleep loss is more relevant than acute deprivation, and the two-way relationship between sleep and memory consolidation.
Research, Education & Career
Working Memory in the Classroom: What Teachers Need to Know
How working memory shapes classroom learning, why some children struggle with instructions and tasks, and what teachers can do to reduce cognitive load.
Executive Function and Career Performance: What Recent Research Suggests
How executive function — updating, inhibition, and shifting — connects to job performance, productivity, and workplace adaptability, based on recent research.
Working Memory Training and Transfer: What 2020s Research Actually Shows
A clear-eyed look at near transfer, far transfer, and why the training question remains one of the most actively studied areas in applied cognitive psychology.
