Classical conditioning and instrumental conditioning are two major behavioral learning theories. Classical conditioning involves forming associations between unconditioned stimuli that naturally elicit a response and conditioned stimuli through repeated pairings. Instrumental conditioning is based on operant conditioning where behaviors are modified by their consequences - positive reinforcement increases a behavior while punishment decreases it. Memory is the process of encoding, storing, and retrieving information. Information is stored in associative networks and schemas in memory. Factors like decay, interference, and environmental cues can influence forgetting over time. Marketers apply principles of learning and memory to influence brand awareness, preferences, and loyalty.
