Q

Stages of prenatal development

A

Zygote: Sperm fertilizes the egg and forms zygote.

Germinal stage: Fertilized egg goes down the fallopian tube and attaches to uterine wall.

Embryonic stage: 8 weeks after germinal period. Size increases by 20,000 times.

Fetal stage: Begins 2 months post conception with measurable electrical activity in the brain.

Q

Assimilation & accommodation according to Piaget

A

Assimilation is the process of interpreting new information in terms of existing schemata.

Accommodation occurs when new information doesn’t really fit into existing schemata; it is the process of modifying existing schemata to adapt to this new information.

Q

Vygotsky’s sociocultural theory

A

The theory that intelligence develops largely as a result of internalization, by children absorbing what they observe in the environment and making it a part of themselves.

Development occurs in part through a zone of proximal development, which distinguishes what children can do on their own (zone of actual development) from what they can do with the assistance of others (zone of potential development).

Stressed that culture and social factors play a role in cognitive development.

Reciprocal teaching, scaffolding, guided participation, play

Q

Bowlby attachment style

A

Attachment: A deep and enduring emotional bond between two people in which each seeks closeness and feels more secure when in the presence of the attachment figure.

Phase 1: Infant reacts identically to every adult & smiling face

Phase 2 (3 months): Infant discriminates familiar & unfamiliar faces

Phase 3 (6 months): Specific attachment - Infant seeks out and responds to mother; emergence of separation anxiety

Phase 4 (9-12 months): Stranger anxiety - response to arrival of a stranger

Phase 5 (2 yrs old): Distress level when separated from carer, degree of comfort needed on return

Phase 6 (3 yrs old): Child can separate from mother without prolonged distress

Q

Harry Harlow attachment theory

A

To study the early relationship between caregiver and infants

Studied Rhesus monkeys; took them away from mother 6-12 hours after birth.

Kept in cages with 2 types of surrogate mothers - one wire cylinder with feeding nipple attached & another cloth covered wooden cylinder with no feeding option.

Monkeys preferred the cloth mother; contact comfort.

Q

Mary Ainsworth attachment style

A

Strange situation procedure to study quality of parent-child relationship

Child kept in unfamiliar room with mother and plays with toys. After 3 min, stranger enters room and talking to mother and child. Then mother leaves and stranger interacts with infant. Then mother returns and stranger leaves. Then infant is left alone. Then stranger returns and interacts with infant. Then mother returns and stranger leaves.

Q

Private speech according to Vyogtsky

A

Language as a means of thinking of mental activities and behaviour; way of guiding oneself

Private changes to inner speech - whispers, silent lip movement

Increases when tasks are challenging, confused on how to process, when mistakes are made

Inverted V shape

Private speech in children with learning difficulties - higher rate; maybe compensation for impairments in cognitive functioning

Q

Social referencing acc. to Bowlby

A

Degree that child looks at carer to check how they should respond to something new (secure base)

23
Q

Critical vs sensitive periods

A

Critical periods: if a specific event doesn’t occur at a specific time, then it will have an impact on development. E.g. Imprinting in Konrad Lorenz and duckings

Sensitive period is the time where if an individual is presented with certain types of stimuli then they would be better at learning or performing certain kinds of behaviour.

24
Q

Key developmental issues

A

Nature vs nurture
Continuity vs discontinuity
Qualitative vs quantitative
Stability vs change

25
Q

Cephalocaudal principles of development

Development occurs from top (head) to bottom (legs)

26
Q

A

Development occurs from the center of the body

outward

27
Q

44
Q

Fetal alcohol syndrome

A

A group of adverse fetal and infant health effects associated with heavy maternal alcohol intake during pregnancy.

Characterized by low birth weight and retarded growth, craniofacial anomalies (e.g., microcephaly), neurobehavioral problems (e.g., hyperactivity), and cognitive abnormalities (e.g., language acquisition deficits); intellectual disability may be present.

45
Q

Teratogens

A

An agent that induces developmental abnormalities in a fetus. The process that results in these abnormalities is called teratogenesis.

Eg: Some medications, recreational drugs, tobacco products, chemicals, alcohol

46
Q

Q

Range of reaction

A

Your genes provide the boundaries that define the minimum and maximum values for many of your characteristics. The space between these boundaries is called the range of reaction.

For example, your genes set an upper and lower limit on how tall you will be when you’re finished growing.

51
Q

____ & ____ applied attachment theory to intimate relationships between adults. They found that there were many similarities between adult intimacy and caregiver-infant relationships.

A

Cindy Hazan & Phillip Shaver

52
Q

Four attachment styles in adults

A

Secure - Able to form deep relationships with intimacy and commitment; believe they’re worthy of love; no problem being alone

Anxious-Preoccupied - Seek high levels of intimacy very quickly in relationships; constantly worry whether partner’s affection is reciprocated; fear being alone and have a low sense of self-worth

Dismissive-Avoidant - Place a large value on their independence and self-sufficiency; avoid entering relationships or engaging in intimate situations; defensive and unwilling to discuss feelings

Fearful-Avoidant - Survivors of a traumatic event, such as abuse; desire close relationships, but also fear the potential negative implications of a relationship; difficulty with trust and dependence on others.

53
Q

Primary and secondary sex characteristics

A

Primary sex characteristics are bodily structures and processes directly involved with reproduction (such as the onset of the menstrual cycle).

Secondary sex characteristics are not directly involved with reproduction but that change dramatically during puberty based on sex (such as the development of male facial hair).

54
Q

Socioemotional selectivity theory

A

Young adults tend to focus on acquiring information that will be useful to them in the future (recalling where they last left their keys), while older adults tend to focus on information that brings emotional satisfaction, such as thinking about their grandchildren.
