NeuroAesthetics?

• Is our perception grounded in shapes? • How does representation and style influence cognition?
1. Content vs. Style 2. Model of AESTHETIC APPRECIATION 3. Interplay Cognition & Emotion 4. Aesthetic Emotions 5. Neural Underpinnings
OUTLINE
• Appraisal of Images • Visual Perception
• Eye Tracking • Aesthetics and Constitution of Meaning
• Epistemological surplus of Form and Aesthetics • Information Visualization as decision making tool
• Interplay between Cognition and Emotion • Images vs Text/Type
Connection To My Research Interests
WHAT IS STYLE?

CONTENT VS STYLE
Correlation between style, depiction and empathy promising field of study for the future!
“There is some evidence that brushstrokes elicit responses in the perceiver, which correspond in direction to motor activation in the direction of the brush (Taylor, Witt, & Grimaldi, 2012).”
Simultaneously performing hand movements that resemble the artist’s made while creating paintings can enhance liking for paintings of corresponding style.
Experts use art styles to classify artworks according to similarity while non-experts don’t.
PREMISES
• Ideal testing ground for theories of emotion, cognition and perception
• Artists often depict the nature of mental representations rather than of physical objects. Their renditions do not adhere strictly to the physical properties of light and shadow and color of objects.
THE PEAK SHIFT PRINCIPLE

GLOBAL, LOCAL PROCESSING
BRIEF HISTORICAL OVERVIEW
1876: Gustav Theodor Fechner, Vorschule der Ästhetik
Early 1900: Gestalt theorists (Lipps, Stumpf, Bühler)
1970ies: Daniel Berlyne, Psychobiological aesthetics
• Early years of 21st century: technological progress improved conditions under which art could be studied in lab situations
• Possibility to study concurrently behavioral, physiological and eye-movement data, neural data
WHAT MAKES AN EXPERIENCE AESTHETIC?
3 major aspects: (Shusterman 1997, Bergeron and Lopes 2012):
1. Has an evaluative dimension - valuation of object
2. Phenomenological - affective dimension
3. Semantic dimension - meaningful
Aesthetic triad-proposal:
(Chatterjee and Vartanian 2014 review of neuropsychological and neuroimaging studies)
1. Sensory-motor 2. Emotion-valuation 3. Meaning-knowledge neural
systems
No reason to believe that all three dimensions required in every instance of aesthetic experience.
FIVE MAIN PROCESSING STAGES 1. Perception
2. Implicit memory integration
3. Explicit classification
4. Cognitive Mastering
5. Evaluation
LEDER ET AL.’S MODEL OF AESTHETIC APPRECIATION
NEURAL UNDERPINNINGS – 4 MAIN CONCLUSIONS 1. Aesthetic appreciation as a complex interaction among
perceptual, cognitive and affective processes.
2. No localized seat for art in the brain; our experience of art emerges from the interaction among the nodes of a broadly distributed network of cortical and subcortical brain regions (Cela-Conde et al. , 2013; Chatterjee, 2014; Vessel et al. , 2012).
3. None of the brain regions is specialized in responding to art alone
4. Resilient to Alzheimer’s: Art can be appreciated in the absence of explicit memory integration
CURRENT RESEARCH STATUS Four challenges faced today:
• Understanding the emotional component of the aesthetic episode • Role of context
• Neural underpinnings of art and aesthetics
• Evolutionary origin
PENDING QUESTIONS • Is the valuation of aesthetic objects computed in
sensory cortices? • What is the relationship between aesthetic judgments
and approach–avoidance responses? • How are different aesthetic emotions, including
negative ones such as horror and disgust, implemented in the brain and how do these emotions give us pleasure?
• How do aesthetic objects evoke moods in viewers that persist after an encounter with an artwork?
• How does expertise in the visual arts alter neural structures and functional responses to aesthetic objects?
• Do brain regions that compute aesthetic judgments overlap with regions that compute other socially and culturally relevant values such as morality and justice?
• What are the evolutionary underpinnings of the ability of the brain to experience aesthetic pleasure?
