Psychology 101 Lectures: Understand Learning, Perception and Scientific Methods
Psychology 101 introduces scientific ways of asking questions about minds and behavior. Perception and learning illustrate how a concept becomes a measurable research problem. Clear definitions and comparisons make the evidence interpretable rather than reducing the subject to memorable labels detached from the processes they describe.

Frequently Asked Questions
What is an operational definition?
An operational definition specifies how a concept is measured or manipulated in a study. It makes procedures understandable, while its suitability for the broader construct still needs evidence and evaluation.
How do sensation and perception differ?
Sensation concerns detecting or registering sensory input, while perception concerns organizing and interpreting it. Their relationship matters, but the same input does not guarantee an identical interpretation under every condition.
Does reinforcement mean any pleasant event?
Reinforcement is defined by its relationship with behavior under the learning framework. An event's pleasant appearance alone does not establish that it increased the relevant behavior in the situation being examined.
Why distinguish negative reinforcement from punishment?
Negative reinforcement involves removal of a condition linked with increased behavior, while punishment concerns decreased behavior. The everyday meaning of negative can obscure those different relationships unless the outcome is specified.
Can a label such as memory explain its own mechanism?
A label identifies a broad concept, while a mechanism describes how the process works. Research needs further distinctions and evidence rather than treating naming the concept as a completed explanation.
