Cognitive processes are the mental activities that let you take in information, work with it, and use it to think, remember, and decide. In Intro to Brain and Behavior, that means looking at how the brain supports perception, attention, memory, reasoning, and problem-solving.
Cognitive processes are the brain-based mental operations that turn raw sensory input into thoughts, decisions, and actions. In Intro to Brain and Behavior, the term usually points to the chain from perceiving information, to paying attention, to holding and manipulating it in memory, to reasoning out what to do next.
A simple way to picture it is this: your senses collect data, attention filters what matters, memory brings in stored knowledge, and reasoning uses that information to choose a response. Those steps do not happen in a neat one-at-a-time line every time. They overlap, and the brain can update one step while another is still going on.
This is why cognitive processes show up so often in decision-making and problem-solving. If you are deciding whether to study, which route to take, or how to answer a case question, your brain is comparing options, pulling from past experience, and predicting outcomes. That is also where mental shortcuts, or heuristics, come in. They make choices faster, but they can also produce errors when the situation is unfamiliar or when your first impression is misleading.
In this course, cognitive processes are not treated as a vague idea about “thinking.” They are tied to specific systems in the brain, especially cortical areas involved in attention, working memory, and executive control. The prefrontal cortex often comes up because it helps coordinate planning, inhibition, and flexible thinking. When that system is under strain, people may become more impulsive, more distracted, or less able to weigh options carefully.
Emotions can also shape cognitive processes. A stressed or anxious brain may notice threats faster, remember some information more vividly, or narrow attention in a way that changes judgment. That is one reason the same problem can look easy in a calm setting and much harder during pressure.
Cognitive processes are the bridge between brain structure and behavior. If you understand them, you can explain not just that someone made a choice, but how the brain got there, from noticing a cue to evaluating it and acting on it.
This term also gives you a way to connect multiple course topics that might otherwise feel separate. Perception affects what gets encoded, memory affects what gets retrieved, and reasoning affects how evidence gets weighed. In a decision-making unit, those pieces come together to explain why people sometimes make efficient choices and sometimes make biased ones.
It also matters because Intro to Brain and Behavior often asks you to move from labels to mechanisms. Instead of saying, “She forgot,” you can describe what happened in attention, encoding, storage, or retrieval. Instead of saying, “He made a bad decision,” you can trace whether a heuristic, emotional state, or limited working memory shaped the outcome.
You will also see cognitive processes in real-life examples, like how someone solves a puzzle, responds to a social situation, or changes strategy after feedback. That makes the term useful for short-answer prompts, case studies, and class discussions where you need to explain behavior using brain concepts rather than just common sense.

Problem-solving is one of the main places cognitive processes show up. You use attention, memory, and reasoning to represent the problem, generate possible solutions, and compare outcomes. In this course, problem-solving is often the behavior you analyze, while cognitive processes are the mental steps underneath it.
Heuristics
Heuristics are fast mental shortcuts within cognitive processing. They save time when you do not have complete information, which is useful in everyday decisions. The tradeoff is that they can push you toward errors, especially when the first answer feels right but is not well supported.
Cognitive biases
Cognitive biases are systematic errors that can come out of the way cognitive processes work. A bias is not random bad judgment, it is a predictable pattern in thinking. In decision-making questions, biases often appear when attention is narrow, memory is selective, or a shortcut gets overused.
Mental Models
Mental models are internal representations that help you organize information and predict what will happen next. They support reasoning because they give your brain a framework to test ideas against. When a mental model is incomplete or inaccurate, your decision-making can go off course even if your attention is good.
A quiz question or short answer might ask you to trace how someone arrives at a choice, then name the cognitive processes involved. You could be shown a scenario and asked whether attention, memory retrieval, reasoning, or a heuristic best explains the response. In a case study, the task is usually to connect behavior to the mental steps underneath it, not just describe the outcome.
If a problem asks why a person made a rushed or flawed decision, look for clues about limited attention, stress, emotion, or a shortcut-based strategy. If the prompt gives a puzzle, debate, or real-world scenario, explain how mental representations and prior knowledge shape the solution path. The strongest answers name the process, show how it works, and connect it back to the behavior in the example.
Problem-solving is the task or outcome, while cognitive processes are the underlying mental operations that make the task possible. You can describe problem-solving by tracing the cognitive processes involved, such as attention, memory, reasoning, and decision-making. So one is the broader behavior, and the other is the mechanism behind it.
Cognitive processes are the brain-based mental steps that turn information into perception, thought, memory, and action.
In Intro to Brain and Behavior, the term is often used to explain decision-making, reasoning, and problem-solving through mechanisms rather than vague descriptions.
Attention, memory, and reasoning work together, so one process can shape the next one instead of operating alone.
Heuristics can speed up decisions, but they can also create cognitive biases when the shortcut fits the situation poorly.
Emotions and stress can shift cognitive processing by changing what you notice, remember, and choose.
Cognitive processes are the mental activities the brain uses to perceive, focus, remember, reason, and decide. In this course, the term connects behavior to the underlying brain systems that handle information. It is usually discussed when you are analyzing how someone thinks through a problem or makes a choice.
Problem-solving is the task or behavior, while cognitive processes are the mental operations that support it. For example, solving a puzzle may involve perception, working memory, retrieval of past knowledge, and reasoning. So problem-solving is the visible action, and cognitive processes are the internal machinery.
Heuristics are quick shortcuts your brain uses during cognitive processing, especially when time or information is limited. They can make decisions faster, but they can also lead to predictable mistakes. In class examples, heuristics often show up when someone jumps to a conclusion before weighing all the evidence.
The prefrontal cortex often comes up because it helps with planning, working memory, and executive control. That does not mean one brain area does everything, though. Cognitive processes use networks across the brain, with different regions contributing to attention, memory, and reasoning.
