Q

3 behavioral learning processes

A
  1. classical conditioning-response becomes triggered by a formerly neutral stimulus
  2. operant conditioning (instrumental)- a particular action is followed by something desired or by something unwanted
  3. social learning theory- emphasizes the influence that other people have over a person’s behavior

Q

Piaget’s periods of cognitive development

A
  1. sensorimotor-birth- 2 yrs- infants use sense to understand world. learning is active. Gain object permanence and think through mental actions
  2. Preoperational-2-6 yrs- kids think magically using language to understand world. egocentric-see from own perspective. imagination flourishes and language becomes a significant means of self expression
  3. concrete operational- 6-11 yrs- children apply logic and interpret objectively, thinking limited to personal experience. Learns concepts of conservation, number, and scientific ideas
  4. Formal Operational- 12-adult- think about hypothetical concepts and reason analytically. can be logical about things they’ve never experienced. Learn ethics, politics, and moral issues

72
Q

what is the reason for the particuluar practice of parent-child sleeping in each culture?

A

US middle class- infants slept in crubs and in their own rooms (more private)
Asia, Africa, and Latin-sleep with parents (separating infants from parents is cruel and crying signals distress)

73
Q

A

newborn: reflexive-cries, movements, facial expressions
2 mos: meaningful noises-cooing, fussing, crying, laughing

74
Q

explain the changes that occur in the infant brain during the first 2 years of life. Discuss the importance of pruning

A

brain growth is rapid during infancy
brain triples in first 2 years, largely due to dendrite growth during transient exuberance
dendrites expand or are pruned based on early experiences; pruning of dendrites actually increases brainpower

Q

explain the views of Skinner and Chomosky and how they differ in their explanations of infant language acquisition

A

skinner believed that parents responses reinforce the development of speech in their babies. Skinner believed parents and other caregivers are teachers of language.
Chomsky believed that infants are born with innate language acquisition device that equips them to learn language on their own. Language learning is the result of neurological maturity

A

negative mood

81

deprivation

83
Q

psychologists from the ______ school of thought believe that a child’s personality is created or largely determined by his or her parents

A

behavioralist

84
Q

theorists in the behaviorist tradition, such as Albert Bandura, include the role of _____ learning in explaining how personality traits form

A

social

85
Q

according to cognitive theory, the set of assumptions that an individual uses to organize perceptions and experiences is called a ______ model

A

working

86
Q

briefly discuss 3 predictors of secure attachment in infants

A
  1. parent’s sensitivity and responses to needs
  2. high level of infant- caregiver synchrony
  3. easy temperament
  4. low household stress
87
Q

4 conditions that can result in an insecure attachment between infants and caregivers. what might be done to improve the level of attachment?

A
  1. high stress of parents
  2. mistreating the child
  3. mother suffering from mental illness
  4. behaving in a intrusive and controlling way
    Attachment may be improved through parental support and education, as well as a change in the stressful conditions
88
Q

why does a child use social referencing?

A

when a child is unfamiliar with a situation, they learn from caregivers what to do

89
Q
