Purpose of class
Consumers do not choose products and services simply by rationally comparing price and functionality. Their decisions are influenced by a wide range of psychological and social factors, including perception, memory, motivation, self-concept, attitudes, people around them, culture, advertising, word of mouth, and social media.

This course aims to help students learn basic concepts from psychology, social psychology, and marketing related to consumer behavior, and to explain familiar products, services, and their own consumption experiences using those concepts.

In the first half of the course, students study fundamental concepts in consumer behavior, such as perception, learning, motivation, self-concept, attitudes, decision making, and social influence. In the second half, the course addresses advertising, online word of mouth, social media, entertainment, fandom, and information search, and considers the relationship between today’s media environment and consumer behavior.
Course description
This course first introduces the foundations of consumer behavior and then examines the relationship between media use and consumer behavior.

In addition to explaining theories, the course uses examples familiar to students, such as food, fashion, smartphones, games, video streaming services, social media, advertising, and retail services. At the end of each class, students complete a short assignment that applies the concepts covered that day to concrete consumer behavior.

The course also includes one guest lecture in the first half and one in the second half. Through these lectures, students learn how companies and practitioners understand consumers and apply that understanding to marketing and service design.

At the end of each half of the course, students write an individual report and analyze actual consumer behavior by combining multiple theories.
Goals and objectives
  1. Understand basic concepts related to consumer behavior and explain them in one’s own words.
  2. Analyze consumer behavior related to familiar products and services using concepts from consumer behavior theory.
  3. Explain the relationship between media such as advertising, word of mouth, and social media and consumer behavior.
  4. Connect multiple concepts with concrete examples and evidence, and express one’s own analysis logically.

Evaluation method and criteria
Grades are based on short assignments in each class (40%), a first-half report (30%), and a second-half report (30%). No written examination will be given.

Short assignments are evaluated based on whether students correctly understand the concepts covered in class, connect concrete examples with those concepts, and explain why a particular consumer behavior occurs rather than merely giving impressions.

The first-half and second-half reports are evaluated comprehensively in terms of conceptual understanding, concrete examples and evidence, analysis and discussion, writing structure, and citation.

The evaluation criteria are as follows.
60% or above: The work meets the requirements of the assignment and explains the topic using basic concepts covered in class.
70% or above: The work appropriately connects concepts and examples and presents a logical analysis.
80% or above: The work integrates multiple concepts and provides an excellent analysis with original discussion based on concrete evidence.
