Laboratory Experiments
Think of lab experiments as the controlled environment approach to psychology research. Researchers create artificial settings where they can manipulate one variable (the independent variable) whilst keeping everything else exactly the same.
The beauty of lab experiments lies in their high internal validity - you can be confident that any changes you observe are actually caused by what you're testing. They're also brilliant for replication since everything follows standardised procedures.
However, there's a major downside: low ecological validity. The artificial lab setting doesn't reflect real-world behaviour, and participants might act differently because they know they're being studied (demand characteristics).
Quick Tip: Lab experiments = high control but low real-world relevance. Perfect for establishing cause and effect, but question whether findings apply to everyday life.
