Neuroscience
is the study of human nervous system, including the brain, its anatomy, functions, and the peripheral system it controls
Consumer neuroscience
points out to the academic approach to employ the knowledge and methods of neuroscience and psychology to understand consumers
Pepsi and Cola example showed:
- Showed the neurobiological basis for brand value
- Demonstrated how the medical devices can be used in the marketing context
Facial expressions
+
Easy and fast
Inexpensive
can measure universal emotions
-
* Internal emotions are not always expressed in facial changes
- Confusion of emotional response (for a
surprise and boredom responses) - Is better for a moving images / videos not
for the static ones
Eye-tracking
Captures:
Fixations
Scan patterns
Pupil/posture changes
Eye tracking:
+
Good for measuring visual attention (time spent looking, where people looked at), and cognitive amount of information, emotions (through pupil dilation and time to first fixation on the stimuli)
Easy to use
Pretty cheap
Easily combined with other technologies
-
When measuring eyes can be difficult with glasses, also when the person is tired
Need to correlate with other reactions or self-reported responses: longer viewing can mean curiosity or cognitive load of information
Electrodermal activity:
+
* Fight / flight reaction
* Good to use for excitation indication
* in time - for movies, played for research
* A good tool to study reactions in a
* mobile environment
-
Answer after 3-5 sec. - shows excitement, emotion, but doesn’t say much about it being positive or negative
Respiration and heart rate:
These measures focus on the beating speed of the heart and how deep and fast a person is breathing.
Heart rate has been found to slow down momentarily when attention increases.
Fast and deep breathing is associated with excitement, while shallow breathing can indicate concentration, tense anticipation, or panic and fear.
Response time:
One way that nonconscious brain processes reveal themselves in behavior is by facilitating or interfering with the speed of response to word comparisons or visual choices.
Response-time measures provide a simple and accessible way to test the strength of association between different concepts.
They’ve been used successfully by neuromarketers in brand, product, and package testing.
Neurological or neurometric measures (based on brain signals) tend to be
both more complex and more accurate than body measures.
Functional magnetic resonance: fMRI
Captures
Oxygenated blood changes in different brain areas
3-5 sec. brain imagery
angl.imaging
Functional magnetic resonance imaging (fMRI):
+
Investigation of deep brain structures - understanding the responses in brain areas
* Spatial 3D brain map
-
Unnatural environment
* Expensive
* It is difficult to do a large-scale study
* License
* Expertise
* Later response, reaction after 3-5 sec.
* Noise
Electroencephalography - EEG
CAPTURES
- Motivation
- Cognitive load
- Drowsiness
- Engagement
Electrodermal activity measurement
Captures:
excitement and emotional arousal (3-5 sec after stimulus exposure)
Electroencephalography (EEG):
+
* Powerful
* Measures instantaneous brain activity
* Portable
* Cheap EEG variants
* Integrated metrics (emotion,
motivation, cognitive load, drowsiness)
-
* Requires time for research
- Requires time for analysis
- Expertise
- Sensitive to movements (more problematic in a
natural environment) - It’s good to match with the eye-tracking in order
to know when the person was looking at when they had a certain brain response
Magnetoencephalography (MEG):
This technique measures minute changes in magnetic fields produced by the brain.
It has many advantages but requires multi-million-dollar machinery that must be super- cooled to near absolute zero to operate.
It’s used in academic studies but hasn’t caught on as a practical method for commercial neuromarketing.
Research process
Planning –> Test –> analysis –> report
Steps and process
- Study goal
- Hypotheses
- Context and method
choices - Data collection
- Pre-processing of the data:
cleaning artifacts, calculating metrics, defining AOI - Data analysis and recommendations
Domains of use
- Branding
- Product design & innovation
- Advertising
- Consumer journey and decision-making
- Online experience
What is consumer neuroscience and neuromarketing? How could it be used?
consumer neuroscience is a field of research that applies neuroscience methods and techniques to understand consumer behavior, including how people make purchasing decisions, evaluate products, and respond to marketing messages.
Neuromarketing, on the other hand, is the application of consumer neuroscience to marketing research and practice.
Neuromarketing techniques include measuring brain activity, eye tracking, skin conductance, and facial expressions to gather data about consumers’ subconscious reactions to advertisements, packaging, product design, and other marketing stimuli.
This data can then be used to inform marketing strategies and improve the effectiveness of advertising campaigns.
Models of Consumer Decision-making and Choice
- Intuitive decision-making model by Genco
- Value-based decision-making by Rangel, Camerer & Montague
- Dual-processing theory by Kahneman & Tversky: cognitive biases
- Hyper choice and choice paralysis
- Constraining factors in consumer decision-making
We continously learn consciously and unconsciously
1) Instincts
2) Learning machine
Neurons transmit information to each other via chemical and electrical impulses through the synapses - these connections help to create and store memories, regulate other functions.
Neurons firing together rather than firing in the specific brain area
17th and 18th century: prenology
* Certain brain areas are responsible for certain functions
* Developed by German physician F.Z.Gall
* Birth for neuroanatomy * Every mental process evoke multiple regions in the brain
