Term
Observer Influence

Term
Structured Observation
Definition
An observational method in which the investigator cues the behavior of interest and observes participants’ responses in a laboratory.
Term

Chapter 2
Definition
Term
Psychosexual Theory
Definition
Freud’s theory that states that maturation of the sex instinct underlies stages of personality development, and that how parents manage children’s instinctual impulses will determine the traits children come to display.
Term
Instinct
Definition
An inborn biological force that motivates a particular response or class of responses.
Term
Eros
Definition
Freud’s name for the instincts such as respiration, hunger, and sex that help the individual (and the species) to survive. (The life instinct)
Term
Thanatos
Definition

Term
Id
Definition
Psychoanalytic term for the inborn component of the personality that is driven by the instincts.
Term
Ego
Definition
Psychoanalytic term for the rational component of the personality.
Term
Superego
Definition
Psychoanalytic term for the component of the personality that consists of one’s internalized moral standards.
Term
Oral Stage
Definition
(Birth - 1 Year) - The sex instinct centers on the mouth, as infants derive pleasure from such oral activities as sucking, chewing, and biting. Feeding activities are particularly important. For example, an infant weaned too early or too abruptly may later crave close contact and become over-dependent on a spouse.
Term
Anal Stage
Definition
(1-3 Years) - Voluntary urination and defication become the primary methods of gratifying the sex instinct. Toilet training produces major conflicts between children and parents. The emotional climate parents create can have lasting effects. For example, children punished for toiling “accidents” may become inhibited, messy, or wasteful.
Term
Phallic Stage
Definition
(3-6 Years) - Pleasure is now derived from stimulating the genitals. Children develop an incestuous desire for the opposite-sex parent (called the Oedipus complex for boys, or the Electra Complex for girls). Anxiety stemming from this conflict causes children to internalize the sex-role characteristics and moral standards of their same-sex parent rival.
Term
Latency Stage
Definition
(6-11 Years) - Traumas of the phallic stage cause sexual conflicts to be repressed and sexual urges to be re-channeled into school work and vigorous play. The ego and superego continue to develop as the child gains mor problem-solving abilities at school and internalizes societal values.
Term
Genital Stage
Definition
(Age 12 and onward) - Puberty triggers a reawakening of sexual urges. Adolescents must now learn how to express these urges in socially acceptable ways. If development has been healthy, the mature sex instinct is satisfied by marriage and child rearing.
Term
Oedipus Complex
Definition
Freud’s term for the conflict that 3-6 year old boys experience when they development an incestuous desire for their mothers and, at the same time, a jealous and hostile rivalry with their fathers.
Term
Electra Complex
Definition
Female version of the Oedipus Complex, in which a 3 to 6 year old girl was believed to envy her father for possessing a penis and to seek him as a sex object in the hope of sharing the organ that she lacks.
Term
Identification
Definition
Freud’s term for the child’s tendency to emulate another person, usually the same-sex parent.
Term
Fixation
Definition
Arrested development at a particular psychosexual stage, often as a means of coping with existing conflicts and preventing movement to the next stage, where stress may be even greater.
Term
Two Main Differences between Freud and Erikson
Definition
Erikson believed children were active participants in their development. Much less emphasis on the sexual drive of development and more of a Cultural one.
Term
Psychosocial Theory
Definition
Erikison’s revision of Freud’s theory that emphasizes sociocultural (rather than sexual) determinants of development and posits a series of eight psychosocial conflicts that people must resolve successfully to display healthy psychological adjustment.
Term
Erikson's - Basic trust versus mistrust
Definition
Infants must learn to trust others to care for their basic needs. If caregivers are rejecting or inconsistent in their care, the infant may view the world as a dangerous place filled with untrustworthy or unreliable people. The mother or primary caregiver, is the key social agent

Birth to 1 year

Corresponding Psychosexual Stage: Oral
Term
Erikson's - Autonomy versus shame and doubt
Definition
Children must learn to be “autonomous” - to feed and dress themselves, to look after their own hygiene, and so on. Failure to achieve this independence may force the child to doubt his or her own abilities and feel shameful. Parents are the key social agents.

1-3 years

Corresponding Psychosexual Stage: Anal
Term
Erikson's - Initiative versus Guilt
Definition
Children attempt to act grown up and will try to accept responsibilities that are beyond their capacity to handle. They sometimes undertake goals or activities that conflict with those of parents and other family members, and these conflicts may make them feel guilty. Successful resolution of this crisis requires a balance: The child must retain a sense of initiative and yet learn not to impinge on the rights, privileges, or goals of others. The family is the key social agent

3-6 years

Corresponding Psychosexual Stage: Phallic
Term
Erikson's - Industry versus Inferiority
Definition
Children must master important social and academic skills. This is a period when the child compares himself or herself with peers. If sufficiently industrious, children will acquire the social and academic skills to feel self-assured. Failure to acquire these important attributes leads to feelings of inferiority. Significant social agents are teachers and peers.

6-12 years

Corresponding Psychosexual Stage: Latency
Term
Erikson's - Identity versus role confusion
Definition
This is the crossroad between childhood and maturity. The adolescent grapples with the question, “Who am I?” Adolescents must establish basic social and occupational identities, or they will remain confused about the roles they should play as adults. The key social agent is the society of peers.

12-20 years

Corresponding Psychosexual Stage: Early Genital
Term
Erikson's - Intimacy versus Isolation
Definition
The primary task at this stage is to form strong friendships and to achieve a sense of love and companionship (or a shared identity) with another person. Feelings of loneliness or isolation are likely to result from an inability to form friendships or an intimate relationship. key social agents are lovers, spouses, and close friends (of both sexes.)

20-40 years (young adulthood)

Corresponding Psychosexual Stage: Genital
Term
Erikson's - Generativity versus Stagnation
Definition
At this stage, adults face the tasks of becoming productive in their work and raising their families or otherwise looking after the needs of young people. These standards of “generativity” are defined by one’s culture. Those who are unable or unwilling to assume these responsibilities will become stagnant and/or self-centered. Significant social agents are the spouse, children, and cultural norms.

40-65 years (middle adulthood)

Corresponding Psychosexual Stage: Genital
Term
Erikson's - Ego integrity versus Despair
Definition
The older adult will look back at life, viewing it as either a meaningful, productive, and happy experience or a major disappointment full of unfulfilled promises and unrealized goals. One’s life experiences, particularly social experiences, will determine the outcome of this final life crisis.

65+ Old Age

Corresponding Psychosexual Stage: Genital
Term
