| Term | Definition |
|---|---|
| Accidental conditioning | Learning that happens by chance when two things get linked together. |
| Classical conditioning | Learning by connecting two things — one that naturally causes a reaction and one that doesn’t. Example: Pavlov’s dogs learned to drool when they heard a bell. |
| Operant conditioning | Learning through rewards and punishments. Example: You study because it gets you good grades. |
| Positive reinforcement | Adding something good to increase a behavior (like giving candy for good work). |
| Negative reinforcement | Taking away something bad to increase a behavior (like removing chores if you behave). |
| Punishment | Doing something to reduce bad behavior (like losing phone time). |
| Extinction | When a learned behavior fades away because it’s no longer rewarded. |
| Insight | Sudden understanding of a problem’s solution (“lightbulb moment”). |
| Latent learning | Learning that happens without trying and shows up later. |
| Shaping | Rewarding small steps toward a goal behavior. |
| Pavlov | Scientist who studied classical conditioning using dogs and bells. |
| Attention | Focusing on one thing while ignoring others. |
| Automatic processing | happens without trying (like reading easy words). |
| Effortful processing | needs focus and effort (like studying facts). |
| Memory construction | Our brains fill in missing details; memories can be changed by bias or context. |
| Delta waves | Slow brain waves during deep sleep (stage 4). |
| Consciousness | Being aware of yourself and your surroundings. |
| Sleep deprivation | Not getting enough sleep; causes tiredness and poor focus. |
| Freud’s view of the unconscious | Unconscious mind hides feelings, memories, and desires. |
| Freud’s view of dreams | Dreams show hidden wishes or feelings. |
| Repression | Pushing painful memories into the unconscious mind. |
| Stages of sleep | Different sleep levels (light → deep → REM). |
| Dream theories | Dreams can show thoughts, help process emotions, or just be random brain activity. |
| Forgetting—Decay | Memories fade if not used. |
| Forgetting—Interference | Old and new memories mix up: Proactive: old info blocks new Retroactive: new info blocks old |
| Eyewitness testimony | Memory of events can be wrong or changed by suggestion. |
| Sensory memory | Holds info for a second (like a quick snapshot). |
| Short-term memory | Holds info for about 20–30 seconds. |
| Long-term memory | Holds info for a long time; nearly unlimited. |
| Encoding types | Imagery: pictures Semantic: meaning Acoustic: sound |
| Algorithm | Step-by-step method that always works to solve a problem. |
| Heuristic | Quick shortcut to solve problems, but not always right. |
| Deductive reasoning | Using rules or facts to reach a sure answer. |
| Inductive reasoning | Making a general rule based on examples. |
| Language features | Semanticity: words have meaning Generativity: can create new sentences Displacement: can talk about past/future |
| Language development | Babbling → one word → short sentences → full sentences. |
| Whorfian hypothesis | Language shapes how we think. |
| Concepts | Logical concepts: clear rules (e.g., triangles have 3 sides) Natural concepts: formed from everyday experience (e.g., birds). |
