negative emotions to form strong connections with products and
brands. Norman’s framework is composed of three interrelated levels
that influence our perception and interaction with the world
(Komninos, 2020):
Visceral Level: This level is concerned with the instinctual and
involuntary aspects of human emotions, which are deeply rooted and
largely beyond our conscious control.
Behavioural Level: This level deals with the subconscious
assessment of situations, leading to the development of purposeful
strategies that are efficient in terms of time and activities required.
Reflective Level: At this level, individuals engage in conscious
thought, reflection, and learning, forming innovative ideas and
generalizations about the world (Komninos, 2020).
These levels, while distinct, are interconnected and collectively shape
our overall emotional perception and interaction with our
environment. The visceral level relates to the initial impact of a design
and the emotional response it triggers. The behavioural level is
associated with the practical experience of using the product, often
linked to user experience. The reflective level involves the user’s
contemplation and analysis of the product , including thoughts and
considerations before, during, and after its use.
