Does relational framing
increase genetic fitness?

"behavior analysts think of the
shaping of behavior as working in
just the same way as the evolution
of species" (Baum, 1994, p. 64).

11
“Both the evolution of species and
the evolution of behavior can be
described as selection by
consequences” (Skinner, 1981)

12
• Selectionism involves an emphasis on the role
historical context and consequences play in
shaping the form and function of the
phenomenon of interest in the current
setting—an emphasis that clearly reflects both
the root metaphor and truth criterion of
contextualism (Fox, 2005, contextualpsychology.org)

Evolutionairy algorithm
(Darwin, 1859)
• If there is variety…
• and if there is selection…
• and if there is heredity…
• ..then there MUST be evolution

Common misconceptions about
evolution
• Evolution has a goal (= “intelligent design”)
• Humans are evolved from apes (= describing
evolution as a lineair process)
• Evolution is only about genes

21
“Darwinism is too big a theory to
be confined to the narrow
context of the gene”
Richard Dawkins, 1976

22
Is the gene the only replicator?

23
The second replicator: the meme
[email protected]
24
What is a meme?
• Any piece of information that has the ability to
replicate itself through imitation
• “Imitation, to mime”  meme (Dawkins,
1976)
• “Unit of cultural evolution”
• Infectious ideas
• Analogy: parasite

Example 1.
“I just can’t get you out of my head”
(Kylie Minogue, 2002)

26
Imitation
• Vertical: from one generation to the next
• Horizontal: spreading of contagious ideas
within one generation
[email protected]
27
Meme-cariers
• Anology: meme-memecarrier,
gene-genotype
• Human brains
• Media: books, CD’s, DVD’s, internet
• Buildings, fashion, music, cultural
manifestations, lectures, congresses,
discussions

Memetic fitness
• Fidelity: the more faithful a copy, the more of
the original information remains
• Fecundity: the faster the rate of copying, the
more the meme will spread
• Longevity: the longer a meme survives, the
more copies can be made from it.

33
Copy the product vs
copy the instruction
• Example: Dutch stue
• Copying the instruction only possible in
organisms that are able to frame relationally
(use language)
[email protected]
34
Meme-gene coevolution
• Memetic drive (Blackmore, 1999)
• Selection of brains that are good in imitating
(mirror neurons!)
• ‘big brain’ theory  physical adaptation of the
brain, relatively big neocortex
[email protected]
35
Genes vs Memes
• The ‘genetic leash’ (Lumsden & Wilson) seems
to be broken  memetic replication does not
have to be good for genes

Contragenetic behavior
• The ‘genetic leash’ (Lumsden & Wilson) seems
to be broken  memetic replication does not
have to be good for genes
• Memes are selfish: their only goal is to get
replicated as much as possible

RFT and memetics are highly
complementary theories which
explain each other’s missing links

RFT and Memetics
RFT
• Selectionistic foundation
• Explains complex human
behavior
Memetics
• Selectionistic foundation
• Explains complex human
behavior
• Evolutionairy function of
contragenetic behavior
unclear
• Psychological mechanism of
imitation unclear

Hypothesis:
Relational framing increases
chance of memetic reproduction
[email protected]
45
Mechanisms
• Stimulus  Relational Framing  activation
of bigger cognitive network  transformation
of stimulusfunction  reproduction of memes

52
Mechanisms
• Stimulus  Relational Framing  activation
of bigger cognitive network  transformation
of stimulusfunction  reproduction of memes
• Memetic reproduction through experiential
avoidance
[email protected]
53
Experiential avoidance and
reproduction of memes
• Death of a loved one  avoidance of painful
experiences  immortal soul living on in
heaven  reproduction of religious/dualistic
memes
• Death of a loved one acceptance of painful
experiences  no need for immortal soul 
no reproduction of religious/dualistic memes

54
Is relational framing itself a meme?
• Relational framing is an idea that gets
replicated
• Relational framing as behavior is taught by
multiple exemplar learing in which imitative
behavior is rewarded in certain contexts
[email protected]
55
Who benefits from combining RFT
and memetical paradigms?
• RFT
- even more complex behavior explained
- increasing ‘evolutionairy validity’
• Memetics:
- psychological mechanism of transmission
explained (copy the instruction)
- methodology (predicton and influence)
