Perception A model of memory

What are the types of memory?Organization of memoryHow memory works

• Storage• Retrieval

Learning

Outline

Hemispheric lateralization

Perception

When do we perceive stimuli?Absolute and differential

thresholds• Just noticeable difference• Weber’s law

Selective – cocktail party Subliminal perception

• Does subliminal perception affect consumer behavior?

Perception

Perception

Does subliminal messaging make people buy? 1956 N.J. movie theater flashed

subliminal messages, “Hungry? Eat popcorn. Drink Coca-Cola.”

• Increased popcorn sales 58% and Coca-Cola sales 18%, but results were not replicated

Erotic stimuli and sexual symbols in ads purported to increase receptivity to suggestions in the ad

Short-term memory (STM)Imagery processingDiscursive processingCharacteristics of short-term

memory• Short-term memory is limited (7±2)• Short-term memory is short-lived

A Model of Memory

Long-term memory (LTM)Autobiographical (episodic) memorySemantic memoryCharacteristics of long-term memory

• Stable memory of events of more distant past• Unlimited capacity• Organized by nodes

A Model of Memory

A Model of Memory

Converting short-term memories to long-term store is physically located in the hippocampus

Elaboration, or rehearsal, of information increases consolidation

Recall from long-term storage is a function of recency and availability Availability is aided if memory is organized into

a well-defined associative network of nodes• Categories• Hierarchies

How Memory Is Enhanced

Semantic network Trace strength

• Accessibility Spreading of activation

• Priming Retrieval failures

• Decay• Interference• Primacy and recency effects

What Are the Types of Retrieval?

Perceptual• “His name started with a ‘J’ . . .”

Conceptual• “A brand of personal computers that

competes with IBM . . .”

Determining relevance is based on existing knowledge structuresInterpretation is subject to prior

learning• Schemas and associations• Categorization• Images• Scripts

Knowledge Structure

Positioning

New brands or products must establish in consumers’ mindsTargetFrame of reference (or category

membership)Point of difference

Target Audience

Must be broad enough to support a meaningful business, but sufficiently discriminating to guide communication and strategy. This is where segmentation strategies are relevant.

Reason to Believe

The category of competing offerings – substitutes – against which the customer should evaluate the relative merits of the brand.

The brand’s competitive, differentiated reason for being – ideally an emotional benefit that uniquely identifies the brand. This is where the elevated value proposition is expressed/how elevated value is delivered.

Differentiated Benefit

Frame of Reference

Implications for Positioning

Product Positioning

For busy, health-conscious adults

Prepared, ready-to-eat packaged foods

Lower fat content, reduced calories

Product Positioning

For adults at risk of heart disease

Any aspirin (acetylsalicylic acid) such as Bayer, Anacin, Bufferin, Excedrin

Safe and gentle

Positioning Problems

Positioning on conflicting claims High quality but low cost Good tasting but low calorie Sweet but nutritious Fast acting but long lasting

Sustaining a benefit over time Benefit relevance may change over decades How to express benefit in modern ways

Entry of me-too brands Usually strengthens incumbent
