2FOUR MAIN AREAS
- Attraction
- Arousal
- Romantic love
- Relationship stability
3IS THIS AN ATTRACTIVE FACE?
4SOME PRINCIPLES OF ATTRACTION
- Baby faces are attractive in women tougher,
swarthier looks for men. - Symmetry is attractive in both sexes
- A low waist/hip ratio is attractive in women
tall, V-shaped men more attractive. - Vulnerability is attractive in women
ruthlessness in men (needing protection vs
commanding resources). - Deep voice attractive in men higher voice in
women. - These are signals of oestrogen/fertility (women)
testosterone/power (men), or signs of general
health/youth.

6 SNIFFING OUT COMPLEMENTARY GENES
- Smell preferences may be connected with a search
for complementary genes that will broaden the
immunity spectrum of our offspring. - Human leukocyte antigens (HLAs) govern our
immune system and can be detected in body
odour. - Some evidence that we prefer different HLAs when
breeding, but similar HLAs when needing family
support (e.g. when pregnant).
7TRIGGERS FOR SEXUAL AROUSAL
- These are based on innate releasers (stored
sexual signals, c.f., instincts/archetypes). - Depend on visual templates (esp. for males).
- Consolidated or modified by early childhood
imprinting (inappropriate fetishism). - Habituation occurs to particular exemplars, esp.
males (Coolidge Effect).

10CHILDHOOD IMPRINTING OF SEX TARGETS
Cross-fostering studies reveal importance of
mother-image. Lambs raised by a goat mother
(left) and kids raised by a sheep mother (right)
fancy the wrong species when grown up (effect
esp. obvious for males, who depend more on
targets.)
11Other Oedipal imprinting studies
- Japanese quail raised by albino mothers prefer
albino mates (Bateson 1978). - Hawaiians of mixed race tend to marry into ethnic
group of opposite-sex parent (Jedlicka 1980). - Women fall in love with men of eye colour more
similar to their father than mother (Wilson
Barrett 1987). - Photos of wives correctly matched by external
judges to mothers-in-law beyond chance
(Bereczkei et al 2002).
12The compulsive attraction of close relatives
reared apart (Star 18/1/88)
13Female fMRI (BOLD) responses to attractive males
Brain areas activated as a young woman views

cortical pattern processing with limbic emotional
areas).

15LOVE IN THE BRAIN
fMRI has also been used to find areas of brain
active when love is experienced. e.g. Brain
responses to pictures of a loved partner are
compared with responses to pictures of
friends. Or, brain responses to romantic
pictures are compared with responses to explicit
erotica. Brain areas concerned with love are the
emotional/social areas such as the amygdala and
insula those concerned with lust are more
animal (e.g brain stem and hypothalamus).
16CONDITIONS FAVOURING LOVE
- High arousal (even negative) promotes love
bonds. - Gazing into each others eyes and sharing intimate
details about oneself (mutual self- disclosure)ma
y create love in the laboratory. - Sexual arousal and pleasure evoke a hormone
called oxytocin (also responsible for
mother/child bonding). - Being in love shares brain chemistry with
obsessional/compulsive states (low serotonin)
17ARE WE NATURALLY MONOGAMOUS?
- Very few animals are monogamous, and even fewer
mammals. Gibbon may be only primate. - Most human societies recognise polygamy those
that dont tend towards serial monogamy. - Males of most species have greater drive towards
partner novelty (promotes gene dispersion). - Women may also benefit from infidelity more
attracted to lovers when fertile. But may flirt
just to keep partner on his toes.
18DON JUAN GENES
This promiscuous, but a gene that increases
production of a hormone in the brain called
vasopressin, transferred from the monogamous
prairie vole, renders it faithful to one partner
meadow vole is normally
19IS THERE A SEVEN-YEAR ITCH?
Asked Ever wished you werent married?, 1 in 5
wives said yes, and 1 in 7 husbands. Peak
discontent occurs 6-9 years after marrying,
though actual divorce peaks later (11-14 years).

22A COMPATIBLE PAIR SHARED TASTES
23THE COMPATIBIITY QUOTIENT
- The CQ Test is designed to predict long-term
success of a relationship (after passion has
cooled). - Comprises 25 items covering areas known to be
important for relationship success. - Answered independently by individuals.
- Each item has 5 possible answers arranged so that
those further apart clash more. - A total discrepancy score is calculated between
the responses of any two people and converted to
a CQ score with an average of 100.
24A TYPICAL CQ TEST ITEM
- How important to you is sexual fidelity?
- 1. Absolutely essential
- 2. Very important
- 3. Odd lapse forgivable
- 4. You have to expect affairs
- 5. Would want an open, swinging, relationship
25MEANING OF CQ SCORES
- 145 Freak identity Typical of test-retest
reliability (same person doing the test twice)
or identical twins. - 130-144 Extremely compatible Exceptionally high
degree of similarity. - 115-129 Very compatible.
- 100-114 Above average. Might work but issues to
be dealt with. - 85-99 Below average. Warning bells sounding.
- 70-84 Rather incompatible. Loud warning bells.
26VALIDITY OF THE CQ
- Two studies have shown that happily married
couples average about 116,compared with 100 for
random pairings. - Those reporting the happiest marriages have the
highest CQ scores. - This is not due to the couple growing more alike
with time but to their degree of similarity at
the outset of the relationship. CQs even predict
the outcome of a 3 minute speed-date. - The CQ has application in on-line dating and
marriage counselling - an early warning of
potential difficulties in a relationship.
27WHY ARE WE SO FASCINATED BY LOVE?
- The reproductive imperative is our most powerful
instinct perhaps the only one (selfish gene
hypothesis). - The final aim of all love intrigues, be they
comic or tragic, is really of more importance
than all other ends in human life. What it all
turns upon is nothing less than the composition
of the next generation (Schopenhauer, 1819)
