Cognitive Connie
Let's explore Key Brain Functions
Understand how the brain performs its most important cognitive tasks — from planning and impulse control to memory, attention, and sustained focus.

Executive Functions
Executive functions are the high-level cognitive processes that allow us to regulate, control, and adapt our behaviour in pursuit of goals. They are the brain's "control system" — overseeing and directing other mental processes rather than performing any single task themselves.
Attention
Attention is the cognitive process that selects some information for further processing while suppressing the rest. It is not a single mechanism but a family of related capacities — selective attention (choosing what to focus on), sustained attention (maintaining focus over time), and divided attention (allocating resources across tasks simultaneously).
Perception
Perception is the process by which the brain interprets and organises sensory information to construct a coherent representation of the world. It is not a passive recording of reality but an active, constructive process: the brain uses prior knowledge, expectations, and context to resolve the inherently ambiguous sensory input it receives.
Consciousness
Consciousness — the subjective, first-person experience of perceiving, thinking, and feeling — remains one of the most profound and contentious topics in psychology and neuroscience. It is simultaneously the most familiar aspect of mental life (we are conscious right now) and the hardest to explain scientifically.
Social Cognition
Social cognition refers to the mental processes involved in perceiving, interpreting, and responding to other people. It is what allows us to infer the beliefs, intentions, desires, and emotions of others — to navigate a social world populated by minds, not just bodies.
Memory Systems
Memory is not a single system but a family of distinct processes and stores, each with its own neural substrate, operating principles, and vulnerabilities. Understanding memory requires distinguishing between how information enters the system (encoding), how it is stabilised over time (consolidation), how it is maintained (storage), and how it is subsequently accessed (retrieval).
