What is the difference between an internal influence and an external influence as described by the Consumer Value Framework (CVF)?. Sociology

Value is a personal assessment of the net worth obtained from an activity (Value = what you get - what you give). Consumer Value Framework (CVF) represents consumer behaviour theory illustrates factors that shape consumption-related behaviours and ultimately determine the value associated with consumption.

Internal influences are things that go on inside of the mind and heart of the consumer or that can be thought of as part of the consumer: such as the psychology and personality of the consumer.

External influences include the social and cultural aspects of life as a consumer. They directly impact the value of activities, although the influence comes from sources outside of the consumer.
