The Emerging Self
First 6 months: Discover physical self
Joint attention – 9 months
Difference in perceptions can be shared
Self-recognition – 18 months
Categorical self (age, sex) - 18 – 24 months
Based on cognitive development
Requires social experience
The looking-glass self: a “reflection”
Some core concepts in the study of the self
Self-concept
A person’s conception and evaluation of one’s self, including physical
and psychological characteristics and skills. At its most basic, this
involves knowledge of the self, as reflected in toddlers’ by visual selfrecognition.
Identity formation
A self-portrait of the different pieces of the self in a coherent and
integrated mode (including, for example, physical, sexual, ideological,
intellectual, relational, vocational, and cultural/ethnic aspects). Erik
Erikson believed that adolescents grapple with their developing adult
identity, asking seriously “Who am I?” and “What do I want to be?”
for the first time.
Self-efficacy
The extent to which a person views him- or herself as an effective
individual. Self-efficacy develops with experience, but young children
believe that they are more competent (efficacious) than they actually
are, frequently overestimating their abilities.
Self-esteem
The judgments people make of their general self-worth and the
feelings associated with those judgments. Researchers have identified
at least five areas of self-esteem: scholastic competence, social
competence, behavioral conduct, athletic competence, and physical
appearance

Emotional Development
Primary Emotions
Emerge during first year of life
distress, disgust, interest, surprise, contentment,
joy, anger, sadness, fear
Secondary (self-conscious) emotions
Emerge during second year of life and depend
on self-awareness and symbolic representation
shame, embarrassment, coyness, shyness,
empathy, guilt, jealousy, envy, pride, contempt
Milestones in emotional development: expression,
recognition, understanding and self-regulation
Emotional expression
1st year: Primary Emotions
- at birth: distress, interest, disgust
- about 1-3 months: joy
- about 3-6 months: anger, sadness, surprise
- about 6-8 months: fear
2nd year: Secondary (Self-conscious) Emotions
- about 18-24 months: empathy, envy (jealousy),
- about 30-36 months: pride, guilt, shame, hubris
Infants and children display a wide range of facial
expressions associated with specific emotions. Can you
identify each emotion the children in the photographs are
expressing?

Emotional recognition
- about 3 months: sensitivity to abrupt emotional caregiver
changes
- about 6 months: (implicit) recognition of all basic
emotions
- about 12 months: social referencing (modeling own
emotional reactions on the basis of the recognition of other
people’s emotional reactions)
Emotional understanding
-about 3-5 years old: Understanding important public aspects of
emotions
- (explicit) recognition and naming of emotional expressions
- how external causes affect others’ emotions
- the impact of reminders on emotions
-about 7 years old: Understanding the mentalistic nature of emotions
- the role of desire and belief in emotions
- the discrepancy between expressed and felt emotions
-about 9-11 years old: Understanding complexity of individual
emotional behavior
- the mixed nature of emotions
- the relation between morality and emotions
- the role of cognition in emotional regulation
Emotional self-regulation
- about 1st year: ability to regulate some disturbing input
- about 3rd year: ability to hide real emotions
- about 5-11 years: increasing ability to self-regulate emotional states
Adolescent depression and maternal rejection: The incidence of clinical depression
in a group of adolescents who experienced low versus high degrees of maternal
rejection as a function of which combination of alleles they possessed for a gene
that influenced dopamine transport. As you can see, only adolescents who
possessed one combination of alleles (TT) experienced significantly greater levels
of clinical depression as a result of high level of maternal rejection (from Haeffel
et al., 2008).
Children’s stress hormones as a function of maternal depression and
medical risk. Cortisol levels at 18 months of age as a function of early
medical risk and maternal depression. Only high-risk toddlers of
depressed mothers had elevated levels of cortisol (adapted from Bugental
et al., 2006).

Stronger rules for boys
A model of phase changes in the rigidity of children’s gender stereotypes
as a function of age. As children first learn about gender characteristics as
preschoolers they become increasingly rigid in their stereotypes, with
rigidity peaking as their gender knowledge becomes consolidated between
5 and 7 years old. Children become less rigid in their stereotypes until
adolescence, when they increase again (not shown in figure) (from Martin
& Ruble, 2004)

A classification of children’s sex-related behaviors. (Adapted from the
Child Sexual Behavior Inventory [Friedrich et al., 1991] and Kaeser,
DiSalvio & Moglia’s [2000])
Communicative Behaviors
- Verbal: for example, “Talks about sexual acts”
- Nonverbal: for example, “Shy about undressing”
Exhibition and Voyeur Behaviors
for example, “Shows sex (private) parts to adults”
for example, “Tries to look at people when they are nude or undressing”
Modeling Behaviors
- Sexually implicit: for example, “Playing doctor-games”
- Sexually explicit: for example, “Imitates sexual behavior with dolls or
stuffed animals”
Self-touching Behaviors
for example, “Touches sex (private) parts at home”
for example, “Masturbate with hand”
Touching-others Behaviors
- Direct: for example, “Touches other people’s sex (private) parts”
- Indirect: for example, “Hug adults he/she does not know well”
Parental Investment Theory (Robert Trivers,
1972)
There is a conflict for both males and females in how much time,
effort, and resources to invest in mating versus parenting
In most mammalian species:
Females invest more than males (female investment is obligatory)
Gamete size (egg larger than sperm)
Internal fertilization and gestation
Nursing
Childcare
Ancestral men and women faced different adaptive problems and
evolved different adaptive mechanisms (this is true for the sexes of
most animals)
Sexuality Over the Life Span
Infant sexuality: CNS arousal
Childhood
Learn about reproduction
Curiosity and exploration
Sexual abuse: like PTSD
Adolescence: sexual identity, orientation
Double standard: decline?
Adult Sexuality
Most are married
Gradual declines
Individual differences
Married have more sex
Male sexual peak: age 18
Female sexual peak: age 38
Men have greater sex drive than women
(controversial)
Men engage in more sexual daydreaming than women
Men report experiencing more spontaneous sexual desire than women
Gay men report having sex more frequently than lesbians
Men report initiating sex more than women
Men masturbate more than women
Women report higher frequency of low libido than men
Men more likely to pay money or present gifts for sex than women
Older Adults
Stereotype: Asexuality
Reality: decline
Diseases and disabilities
Social attitudes
Lack of a partner
Physiologically able in old age
Incest Avoidance
Westermark (childhood familiarity results in incest avoidance) versus
Freud (Oedipal and Electra complexes)
Wolf: “minor marriages” in Taiwan
Compared to “major marriages,” minor
produced 40% fewer children
had three times higher divorce rate
wives more likely to admit to extramarital affairs
Shepher: Israeli kibbutzim
Of 2869 couples from 211 kibbutzim, no marriages between members from
the same kibbutz.
Post-adoption incest and genetic sexual attraction
highly intense, sexual attraction, often leading to incestuous relations,
experienced by close kin who have been separated at or soon after
birth and reunited as adults.
Most data on this phenomenon are anecdotal
Greenberg and Littlewood’s (1995) survey of post-adoption counselors
in London indicated that about 50% of clients who had been reunited
with kin as adults experienced, “strong, sexual feelings.”
Mechanisms for Westermark effect
Olfaction
Evidence of the functions of pheromones in animals and humans for
both kin recognition and sexual attraction
Parents can distinguish between the odors of their biological children,
except in the case of identical twins
Mothers cannot identify stepchildren by odor
Preadolescent children can identify their full sibs but not half sibs or
stepsibs by odor
Olfactory cues may mediate favoritism of blood relatives
Weisfeld et al. (2003), studying human families
immediate family members exhibited particular patterns of aversions to
each other’s odors.
Fathers showed aversions to their daughters’, but not to their sons’
odors.
Mothers did not display any aversions
Opposite-sexed, but not same-sexed sibling pairs, showed aversions to
each other’s odors.
These patterns occurred whether or not the source of the odor was
recognized, and whether or not the individuals involved were
biologically related.
Attachment Theory
Bowlby: A strong affectional tie that binds a person to an
intimate companion
Measured by:
proximity behaviors,
distress upon separation,
extent to which the attachment figure can calm infant
Helps regulate distress by proximity seeking
By about 6-7 months
Ainsworth: special, irreplaceable people
Desire to maintain proximity
Derive a sense of security

Theories of Attachment
Psychoanalytic Theory: “I love you because you feed
me”
Learning Theory: “Rewards lead to love”
Cognitive-Developmental Theory: “To love you I must
know you”
Ethological (Evolutionary) Theory: “Perhaps I was
born to love”

Social responsiveness
At birth: undiscriminating
2-6 mo: preferences develop

Over-stimulation/under-stimulation
Attachment-Related Fears
Separation anxiety: 6-8 mo
Peaks around 14-18 mo
Gradually wanes
Stranger anxiety: 8-10 mo
Declines during 2nd yr
Ainsworth: secure base for
exploration

Interactions during childhood
During childhood, peer social interaction focuses on play
Sex segregation common
Physical aggression during early childhood, relative to toddlerhood,
decreases while verbal aggression shows the opposite pattern (Coie &
Dodge, 1998).
Relational aggression: manipulating social relations by shunning and
spreading rumors, among other strategies.
Relational aggression increases with age as children’s cognitive
abilities improve, but is used more by girls than boys
Peer-directed aggression is first observed at the end of the
first year of life and typically occurs in the context of
object disputes (Coie & Dodge, 1998).
Up to 50% of the interaction between toddlers is
conflictual, though not aggressive
Bullies and victims
The form of aggression that comes to the fore during late childhood
and adolescence is bullying and victimization
Bullies are more frequently boys than girls and represent about 10% of
the elementary school population in most industrialized counties
boys use physical aggression in bullying same-sex peers and girls use
relational aggression with other girls
Victims of bullies tend to be physically frail children with few friends
or affiliates
Aggression as a solution to adaptive problems
Co-opt resources of others
Defend against an attack
Inflict costs on intrasexual rivals
Negotiate status and power hierarchies
Deter rivals from future aggression
Deter long-term mates from sexual infidelity
Potential benefits of aggression must be balanced
with costs
Aggression tends to cause retaliatory aggression
Aggression to maintain reputation and status
“Honor” killings of sisters/daughters to maintain status in
community
Willingness of victim to retaliate
Reputation as both a bully or victim can be deleterious
Young-male syndrome
Males, at all ages, engage in more physical aggression than females
and the aggression that adolescent and young-adult males engage in is
more likely to lead to serious injury and sometimes death
Greater male aggression can be explained in terms of parental
investment theory
Intrasex competition
Impress females via competitive risk taking
Risk taking and accidents are frequently the result of competitive or
“show-off” behavior, with the purpose being to compete with other
members of the same sex or to impress members of the opposite sex

Dominance hierarchies
Status with a group
Influences access to resources, such as food and mates
Establishing high status achieved by combination of
aggression and cooperative interaction
Dominance hierarchies:
Reduce antagonism within the group
Distribute scare resources
Focus division of labor
Establishing Dominance Hierarchies
“leaders” recognized early,even in transient groups.
In children, top and bottom of hierarchies established first, middle
areas later
Even preverbal toddlers in groups form dominance hierarchies
In childhood, hierarchies usually in same-sex groups
Interaction in same-sex groups serves to foster development of social
skills
Children with mostly opposite-sex friends are less-well adjusted than
children with mostly same-sex friends (Kovacs et al., 1996)
Both aggression and affiliative behaviors used to
establish and maintain dominance
Evidence in:
chimpanzees (de Waal)
preschoolers (Hawley)
school children and adolescence (Pellegrini)
In preschoolers level of aggression positively associated
with popularity (Hawley; Vollenweider et al.)

Stepparent Investment: Cinderella or Marsha
Brady?
Stepparents should show little interest in the welfare of children who
are clearly not their biological offspring
Why should stepfathers invest at all?
Stepparenting as mating opportunity. The best strategy for a man when
looking for a new mate may be to act solicitously toward the potential
mate’s children
It’s more difficult for stepparents to develop strong emotional bonds
with stepchildren than with biological children
In one study of middle-class stepfamilies in the United States, only
53% of stepfathers and 25% of stepmothers claimed to have any
“parental feelings” whatsoever for their stepchildren (Duberman,
1975)
How much do stepparents invest?
Anderson et al. (1999a,b): South Africa & U.S.: stepfathers spent
significantly more money on their natural children than on their
stepchildren
Zvoch, 1999: Stepfamilies saved less money for their children’s
education, started savings accounts for children later, and expected to
spend less money for their child’s education in the future.
Stepfathers spend significantly less time with their stepchildren than
with their natural children (3 hours less per week with their
stepchildren than with their natural children); play with them less
often. Pattern found cross culturally: U.s. South Africa, Caribbean
islands
less money is spent on food when a child is reared by an adoptive,
foster, or stepmother than a biological mother (Case et al.)
“Wicked” stepparents?
Daly & Wilson, in survey of Canadian households: Children were 40
times more likely to be abused if they lived with a stepparent versus
two natural parents.
This difference remained even when possible influencing factors that
may be associated with stepfamilies, such as poverty, the mother’s age,
and family size, were statistically controlled. Given these and similar
findings
“Stepparenthood per se remains the single most powerful risk factor
for child abuse that has yet been identified.”
Child homicide: Studies in different countries report that for children
under 2-years of age, homicide 40 to 100 times more likely at hands of
stepparent (usually stepfather) than natural parent.
