adaptation

• biological feature that shows design for some function

• ultimate function = advantage in terms of survival and/or reproduction

explaining fiction

• art in general– common features despite differences– music, dance, visual art precede story and

verse

• narrative– purportedly true report

• fiction– events acknowledged invented

art as adaptive?

• universal• thousands of generations• same major forms across cultures:

– music, dance, visual art, fiction, verse

• high costs in time, energy, resources• stirs emotions• develops reliably in childhood without

training

Pinker’s challenge

• art as byproduct (Pinker 1997, 2002, 2007)– except for scenario-building function of

narrative– byproduct of design capacity and human

cognitive preferences• cheesecake for mind• presses pleasure buttons by defeating locks

byproduct, sexual selection, adaptation

• if no benefits and high costs, would have been eliminated– cf. Dawkins 2004 on beaver dams

• sexual selection: Geoffrey Miller 2000

art and pattern• = cognitive play to engage human attention

through our preference for pattern

• pattern allows rich inference• human appetite for open-ended pattern• strong single pattern reduces need to attend• but unpredictable combinations of patterns repay

attention and yield rich especially inferences• art concentrates interrelated and intersecting patterns

play

• flexible behaviors cannot be entirely innate– need fine-tuning, wide options, context-sensitivity– especially urgent behaviors: flight, fight

• those with stronger motivations to practice and explore in low urgency will fare better in high urgency

• therefore evolution of pleasure in play• repeated and exuberant play hones skills, widens

repertoires, sharpens sensitivities– e.g. rat play drives genetic transcription in amygdala

and frontal cortex

art as play

• cognitive capacities benefit from – finer fine-tuning– wider repertoire– greater context-sensitivity – faster processing speed

• e.g. aural, visual, vocal, manual, social skills• art as cognitive play

– supernormal stimulus– rewards attention, repeat engagement

attention

• art needs to earn attention • attention to others unique in humans from birth• protoconversation, from c. 8 months

– “more like a song than a sentence”– “multimedia performances”:

• eyes, faces, hands, feet, voice, movement• rhythmic turn-taking, mutual imitation• elaboration, exaggeration, repetition, surprise

• joint attention, c. 12 mos• sharing attention ensures cognitive play does not

lead to private worlds

art: functions

• 1: cognitive fine-tuning in key modes• 2: social attunement

– attunement in sound and movement associated with close cooperation in parrots, duetting songbirds, dolphins, gibbons, humans

– in humans also in visual terms: group styles in body adornment, artifacts

– in humans also in fiction: empathy with characters, prosocial values, attunement with audience

art: functions

• 3: individual status– attention correlated with status– in spontaneous conversation, status earned by

relevance– art can hold attention in ways that override or

create own relevance

art: functions

• 4: religion• emergence of tradition

– imitate successful– imitate most common

• new initiatives become model, fashion, tradition, jealously guarded norm

• religion and art– spirits assumed to respond like humans– supernatural world dependent on fiction, in invented story– religion coopts art

• perhaps even becomes main function of art in traditional, small-scale societies

art: functions

• 5: creativity• art as Darwin machine (cf. immune system, neural

Dawinism)– 1: blind generation of variations: through neural randomness– 2: selective retention of external form (vs dream, reverie)– 3: self-motivating– 4: low-cost testing mechanism in makers’ minds– 5: status as incentive to refine– 6: further, more objective testing in minds of others– 7: human imitation: recycles existing design success– 8: traditions reduce invention costs and pose well-defined

problems

art: functions

• 5: creativity• art as Darwin machine (cont.)

– 9: traditions and forms reduce attention and comprehension costs

– 10: habituation ensures innovation (Martindale 1990)

• art well designed for creativity but not useful creativity• but even utilitarian effects

– materials, processes, products: e.g. in weaving and potterty– design tools: drawing, model-building

• confidence in creating parts of world on own terms

narrative

• comprehending events– animal and infant cognition: intuitive physics,

biology, psychology– human Theory of Mind: by age 5:

• beliefs as well as desires and intentions• metarepresentation

• communicating events– animal communication: present threats and

opportunities (vervet monkeys, honeybees)– human extras: joint attention, imitation, language

narrative

• inventing events– human pretend play– c. 12 months, manipulating objects as if something else– c. 24 months, pretense easy and fun– pretend play outstrips sophistication in understanding events– attention-engaging surprise more important than realism– fiction as internal pretend play, without props and actions

fiction as adaptation

• emerges after music, dance, visual arts• universal, spontaneous• we cannot suppress response:

– cannot not imagine characters in verbal or visual fictions

• cognitive defects:– Autism (vs Williams syndrome):

• poor Theory of Mind• poor story comprehension• no spontaneous pretend play

fiction: functions

• 1: social cognition– producing and processing social information – scenario construction or recall

• 2: storyteller status• 3: prosocial models

– audience resistance to selfish manipulation– but audience responsiveness to prosocial

manipulation, to shared values

• 4: perspectival shift– to make characters on both sides come to life

fiction: functions

• 5: thinking beyond here and now– cannot think sustainedly in abstract– but can think well in terms of agents and actions

• 6: Theory of Mind: explanation as problem, story as solution– Theory of Mind: awareness of false belief, of what we may

not know– agential (and especially unseen-agent) explanation

• 7: religion: supernatural fictions and social cohesion

varieties of fiction

• religion (myth) has commandeered much of force of fiction

• but non-religious or unserious fiction alongside religion’s serious fiction (Islam and Arabian Nights, Shakespeare, Kalibari)

• low cost, high long-term benefit: parables, fables• low cost, high immediate benefit: jokes• high cost, high immediate benefit: popular fiction• high cost, high long-term benefit: serious fiction

conclusion

• art entices minds to play hard and often so they can work harder– fine-tunes key perceptual and cognitive

modes– fosters creativity

• fiction – improves social cognition– thinking beyond here and now

conclusion

• need tests against alternatives (byproduct, sexual selection, other adaptive explanations)

• evolutionary approach to art and literature does not depend on art and fiction as adaptations– but a naturalistic account of art and fiction

needs to know!
