Q

what is the primary characteristic of the period of the zygote

A

rapid cell division, the cells divide exponentially, from 2 to 4 to 16 to 256, and as cells divide, the centre of the cell becomes hollow

Q

ectopic pregnancy

A

a pregnancy that results from the implantation of the blastocyst into one of the fallopian tubes instead of uterine wall (mother and the zygote are at risk)

Q

what is the difference between uterus and fallopian tubes that makes ectopic pregnancy risky

A

unlike the uterus that can expand and contract to accommodate and expel the fetus, the fallopian tubes do not have this ability. if the pregnancy is not terminated, there is a risk of rupturing fallopian tube, leading to death

Q

monozygotic twins

A

“identical twins”, they have 100% shared genetics. it occurs when one egg was fertilized by one sperm and splits into two separate cells with identical DNA (almost identical genetic information, and always the same sex)

Q

dizygotic twins

A

“fraternal twins / non-identical twins”, occurs when in the rare case of woman’s ovaries releasing more than one egg at a time, two eggs are each fertilized by separate sperm cells. approx sharing 50% of their genetic information (may be of diff sexes, similar to other siblings born years apart)

  • fetal brains develop the sulci and gyri
  • fetus learn from the world outside the uterine environment
  • they can discriminate between the voice of their mother and unfamiliar woman
  • pregnant ppl can recognize how their fetuses behave, which may be indicators as to how infants would behave after birth

Q

what are the three factors associated with teratogens that adds to the complexity of effects of teratogens on prenatal development

A
  • dose: how much exposure a pregnant person had to a teratogen
  • timing: when in gestation the teratogen was experienced
  • cumulative effects: the possibility that the pregnant person may have been exposed to more than one teratogen and the effects combined may be difficult to disentangle

Q

we know that only thru experiments can we determine causation, but why is it unethical to conduct experiment on pregnant people to determine possible teratogens

A

It is unethical to randomly assign pregnant women to an experimental condition (e.g., exposure to teratogens) that might negatively impact their developing infant.

Q

why do children struggle with conservation tasks

A

they do not yet realize that certain physical qualities of an object remain unchanged despite changes to its physical appearance (tasks may focus on liquid, mass, number, or length)

61
Q

concrete operational period

A

third stage of cognitive development, lasting from ages 7 to 11, marked by increased cognitive ability in reasoning about concrete events (limited to the here and now in their thinking, thinking about hypothetical situations is difficult)

62
Q

why do children succeed at conservation tasks during the concrete operational period

A

children understand three transformative principles: identity, compensation, and inversion

63
Q

identity

A

objects remain what they are even when they are manipulated

64
Q

compensation

A

occurs when children recognize that the imposed changes cancel each other out. one change to an object is negated by an opposing change to that object, the object remains in its initial state after these opposite changes

65
Q

inversion

A

children realize that each of the processes imposed in conservation tasks is easily reversible

66
Q

Lev Vygotsky’s sociocultural theory

A
  • portrayed cognitive development as a continuous process (as opposed to Piaget’s discontinuous progress) that was intimately linked to the context in which children grew up. he viewed adults as central to promoting cognitive development
  • how broader social influences impact cognitive development (importance of psychological tools in shaping the way individuals structure their thinking)
67
Q

scaffold

A

cognitive support offered by a teacher to a learner that helps the latter acquire new skills or knowledge, support is withdrawn once the learner can perform the skill on their own

68
Q

what is the purpose of providing cognitive scaffolding

A

the assistance adults provide allows children to achieve more than they would be able to achieve by themselves

69
Q

zone of proximal development

A

the distance between what a child can accomplish alone and what a child can accomplish with some assistance

70
Q

according to Vygotsky, what is the most important psychological tool and why

A

language, it is embedded in our thoughts and we often use language (even if only internally as inner speech) to regulate our behaviour and solve difficult problems

71
Q

egocentric speech

A

children talk to themselves out loud to help them solve difficult problems, which is then internalized over time and become silent inner speech

72
Q

evidence of infants developing social understanding?

A

infants show preferences for their mother’s voice shortly after birth relative to other female stranger or their father’s voice, they also quickly learn to engage in social interactions with others

73
Q

the still face paradigm

A

used to evaluate infants’ emerging understanding of social relationships. infant is seated across from the mother, who is at first actively engaging the infant, then is instructed to adopt a still face (neutral emotion and no response) to examine the infant’s reaction. the infants often exhibit distress

74
Q

how does covering portions of our faces affect the accuracy of identifying emotions?

A

researches indicates that children aged 7 to 13 years accurately identified emotional expressions even when portions of faces were covered. similar experiment were conducted on younger children, and the findings suggest that mask wearing impairs emotion recognition to a greater extent in young children relative to older children and adults (also suggest that we rely on other cues, situational or environmental factors, to identify emotional expressions)

75
Q

attachment

A

refers to the manner in which we interact with our primary caregivers as infants and with our romantic partners as adults

76
Q

what’s Konrad Lorenz discovery

A

found that goslings followed the first large moving object they saw immediately after hatching and showed a preference for this object

77
Q

imprinting

A

suggests that young organisms may be biologically predisposed to form relationships with the adults of their species

78
Q

what is the purpose of developing early attachment

A

early attachment is based on biological underpinning and survival of the mammalian species

79
Q

Harry Harlow’s experiments on the hypothesis of early attachment

A

he conducted experiments with non-human primates to examine whether attachment to a mother was based on sustenance or comfort. suggested that infant monkeys are born with an internal need to cling to a soft body (cloth mother) and this drive is just as powerful as other biological drives (hunger)

80
Q

sustenance

A

the provision of food

81
Q

comfort

A

the provision of warmth and the ability of the mother to serve as a secure base

82
Q

John Bowlby

A
  • one of the first psychologists to theorize about attachment relationships in infancy
  • believed that mammals develop attachment bonds as a means of promoting their survival and, without them, infants would perish due to a lack of food or protection
83
Q

the Strange Situation paradigm

A
  • developed by Mary Ainsworth, allowed researchers to systematically explore the attachment relationships infants develop with their primary caregivers, and some of the factors that contribute to the emergence of attachment relationships
  • a 21-minute observational assessment that places an infant, mother, and a stranger in eight situations, with a focus on how infants behave in different situations as well as how infants and mothers interact when alone and when in presence of the stranger
84
Q

what are the three primary attachment classifications identified by Ainsworth

A

securely attached, insecure-resistant, and insecure-avoidant

85
Q

securely attached

A

an attachment style of infants and adults characterized by emotional closeness and a healthy level of independence and exploration (distressed when mother left but happy again when she came back)

86
Q

insecure-resistant

A

an attachment style of infants characterized by being clingy and resisted separation from their caregivers, may be born out of inconsistent parental responsiveness (fearful of the stranger when mother left and engage in additional contact-maintaining behaviour once the mother reappeared)

87
Q

insecure-avoidant

A

an attachment style of infants characterized by avoidance of a primary caregiver upon reunion after separation, may be born of out parental disengagement with the infant (minimal anxiety and distress when left alone with the stranger, and actively avoiding the mother when she reappeared)

88
Q

disorganized attachment

A

a fourth attachment classification that has been recently identified. an attachment style of infants characterized by extreme fear and dissociation in wanting to both approach and avoid an attachment figure, may be born out of parent abuse

89
Q

Heinz dilemma

A

in Lawrence Kohlberg’s theory of moral development, a vignette (short story) presenting a moral dilemma to assess moral reasoning

90
Q

what are the three primary stages of moral reasoning in Kohlberg’s theory of moral development

A

pre-conventional morality, conventional morality, and post-conventional morality

91
Q

pre-conventional morality

A

the first stage of morality in which children think of morality in terms of punishments and rewards

92
Q

conventional morality

A

the second stage of morality in which a child places value on social conventions, social order, and being viewed as “good” or “bad” by others (conforming to societal pressures)

93
Q

post-conventional morality

A

the final stage of morality in which someone bases moral decisions on abstract principles instead of on societal expectations or the judgment of others (develop their own ethical principles)

94
Q

formal operational period

A

the fourth stage of cognitive development, starting approx age 12 (some may never achieve this level). marked by the ability to think abstractly and consider hypothetical situations

95
Q

executive functions

A

higher-order cognitive processes that, in many ways, make us human, including abilities related to planning for the future, controlling impulses, mentally manipulating and working with information, switching between tasks with distinct but similar response demands, and making complex decisions

96
Q

which brain region undergoes significant development in adolescence?

A

the prefrontal cortex experience synaptic pruning and myelination during adolescence

97
Q

correlation between quality of social contexts and likelihood of reoffending for adolescence

A

positive social contexts are associated with lower rates of reoffending by juveniles with better impulse control

98
Q

adolescent egocentrism

A

adolescent’s perception that others are focused on them, their feelings and actions (聚光燈效應)

99
Q

Elkind’s take on adolescent egocentrism

A

suggested that individuals differentially focus on what is of interest to themselves over what is likely of interest to others. adolescent egocentrism is characterized in part by an imaginary audience, in which they think that everyone is focused on them, and personal fable, in which they think of themselves as unique and invulnerable to risky situations

100
Q

what are the four identity statuses developed by James Marcia

A

foreclosed identity, identity diffusion, psychosocial moratorium, and identity achievement

101
Q

foreclosed identity

A

individuals who have prematurely decided who they are, likely conforming to the ideas of or expectations set by others (high commitment and low exploration, they might take the path of least resistance)

102
Q

identity diffusion

A

individuals who have not made any decisions or commitments about their identities (low commitment and exploration, they might avoid making decisions and leave everything undecided)

103
Q

psychosocial moratorium

A

those who are exploring various options (low commitment and high exploration, they might take extended journeys to find themselves before making commitments)

104
Q

identity achievement

A

those who have completed their identity crisis and have committed to who they believe themselves to be (high commitment and exploration, they might gather information on lots of career paths before committing)

105
Q

psychoanalytic approach on parent-adolescent relationship

A

suggests that emerging peer relationships compensate for changes in parent-adolescent relationships

106
Q

socialization model’s perspective on parent-adolescent relationship

A

suggest that peers serve as competition for parents

107
Q

cognitive model’s perspective on parent-adolescent relationship

A

suggest that peers provide novel input and serve to complement parent-adolescent relationships

108
Q

which relationship is most important when considering predictors of good adolescent mental health and well-being

A

parent-adolescent relationships may be crucial to well-being in the teenage years

109
Q

describe the negative correlation between age and cognitive performance around age 18 to 50

A

increased age is associated with poorer performance on measure of fluid intelligence (speed of processing and reasoning), but stable performance on measures of crystallized intelligence (vocab or concrete information learned over time)

110
Q

how can the elders improve fluid intelligence

A

by engaging in stimulating cognitive activities over 10 to 12 weeks (mental workouts yield positive effects)

111
Q

dementia

A

deterioration of brain function that negatively impacts cognitive processes (memory, language and judgment) and includes a range of diseases including Alzheimer’s disease, Lewy body disease, and Parkinson’s disease

112
Q

Alzheimer’s disease

A

a disease marked by the gradual onset of impairment in cognitive functions of memory, reasoning, and judgment (most common forms of dementia), along with increased confusion and depression that increasingly complicates the completion of activities for daily living

113
Q

preventions from Alzheimer’s disease

A

even though the likelihood of developing this disease is due to genetic makeup, participating in various kinds of stimulating environments, such as having a strong social network, stay intellectually engaged, and being physically active, or even 10 minutes of light exercise impact memory performance in young adults

114
Q

social clock

A

cultural norms and societal expectations about the timing of key life events such as marriage, having children, and retiring

115
Q

emerging adulthood

A

a period of development ranging from the late teens to the mid-20s marked by identity exploration, instability, self-focus, and exploring possibilities for one’s life

116
Q

when was the association between early and later attachment classifications studied

A

the 1980s, by psychologists Cindy Hazan and Phil Shaver noticed the similarities between infant-caregiver attachment and adult romantic relationships and sought to explore the connection

117
Q

what are the three attachment styles in adults that parallel those observed in infants

A

using the Adult Attachment Interview technique, Mary Main identified secure or autonomous, anxious or preoccupied, and avoidant or dismissive (a fourth one for individuals whose attachments can’t be determined on the collected data)

118
Q

secure or autonomous attachment style

A

like securely attached infants, react to relationships in an even and positive manner. they are comfortable and confident in their ability to become emotionally close to others, and enjoy a balance of closeness and independence

119
Q

anxious or preoccupied attachment style

A

parallels the insecure-resistant style in infants. they tend to feel uncomfortable with independence and strive for constant intimacy and closeness. they are often unable to find romantic partners willing to react similarly due to their high levels of relationship needs

120
Q

avoidant or dismissive attachment style

A

parallels the avoidant attachment classification in infants. they are perfectly comfortable without close emotional relationships, and tend to believe that close relationships will compromise their independence so they often avoid such relationships altogether

121
Q

unhappy marriage’s impact on one’s health

A

troubled marriages can directly impact health and mortality by interacting with our cardiovascular, endocrine, and immune systems

122
Q

how does having a baby impact the marriage

A

marital satisfaction generally decreases after the birth of a child, but researches indicate that parenthood is positively related to happiness, meaning in life, and positive emotion

123
Q

what factors are associated with better adjustment to retirement

A

having better psychological health, higher income, and being married

124
Q

socioemotional selectivity theory (SST)

A

a theory on aging which specifies that one’s perception of time impacts selection and pursuit of goals, with younger adults favouring information-related goals and older adults favouring emotion-related goals tied to well-being and relationships (older adults learn to avoid negatively arousing stimuli)

125
Q

bereavement’s impact on one’s emotional and physical health

A

increase risky behaviour and impact moral decision making, also taking a toll on physical health (higher rates of disability, hospitalization, medication, and depression)

126
Q

what factors help ease the pain of loss of loved ones

A

having a strong social support and developing new interests (the loss of loved ones may inspire reflection on the meaningfulness of the event or self-examination)

127
Q

Erik Erikson’s eight stages of psychosocial development

A

beginning in infancy and ending in late adulthood, individuals must conquer each challenges to move forward to the next developmental milestone, whereas those who fail may experience issues associated with that domain across the lifespan

128

  • infancy: birth to 2 years
  • infants learn to trust their caretakers and the world around them
  • if failed, infants develop a sense of mistrust
129
Q

autonomy vs shame and doubt

  • if failed, children believe they are unable to make positive decisions on their own
130
Q

initiative vs guilt

  • preschool years: 4 to 5 years
  • children develop a sense of purpose and initiative
  • if failed, children develop a sense of guilt and view themselves as a nuisance to others
131

132
Q

identity vs role confusion

133
Q

intimacy vs isolation

  • if failed, adults feel stuck, unfulfilled, and unproductive
135
Q

ego integrity vs despair

A
  • maturity: 65+ years
  • adults see themselves as having lived a successful life and will develop integrity and contentment
  • if failed, adults may be plagued by the belief that their lives were unproductive and feel despair, depression, and hopelessness
136
Q

how are developmental researches conducted

A

through longitudinal research (provide unique information about developmental processes, whether growth is characterized by stability or change) and cross-sectional research (children of various ages are tested in the same study, useful for examining age-related change, but not development within the same person over time).

137
Q

difficulties associated with collecting data from children

A
  • neonate have limited motor control, cannot easily communicate their thoughts, feelings, or needs. so developmental psychologists have focused their studies with young ones on reflexive, involuntary, and obligatory behaviour
  • researches on children will increase their focus on voluntary behaviours
  • combining parent-report and self-report data
138
Q

novelty preference

A

the preference of infants in looking longer at new information in the environment, as compared to old information

138
Q

habituation prardigms

A

infants are presented with an interesting stimulus until they habituate to it, or lose interest in it. once they lose interest, they are presented with a new stimulus. if infants notice a difference between the two stimuli, they normally look longer at the new stimulus. the findings suggest that infants remember information about visual stimuli and this memory may inform where they choose to look

138
Q

high amplitude sucking paradigm

A

infants are given a sterilized pacifier to suck on for a certain period of time. the initial baseline period is used to establish how much infants such on the pacifier in the absence of any outside stimulation. findings suggest that infants preferred listening to speech relative to non-speech

139
Q

theory of mind

A

an ability that emerges around age 4, which allows people to understand that others have feelings, thoughts, and desires that differ from one’s own (identified through the use of false belief paradigms)

140
Q

false belief paradigm

A

showing a child a box of band-aids and ask the child what he thinks is inside the box. common answer would be “band-aids”, but research open to reveal unexpected contents. the child is then asked to think what others think is inside the box, to which comes two types of answer
- those without a theory of mind: others will think there are treats
- those with a theory of mind: they will think that there are band-aids in the box

141
Q

recall memory

A

the ability to recount specific episodes or events from the past

142
Q

elicited imitation

A

a three-dimensional behavioural recall task. infants and young children interact with three-dimensional event sequences, items they interact with in the lab differ from those found at home in that the lab-based events can be used to create a sequence of events that they find interesting or entertaining. findings indicates that recall capability are much more sophisticated than Piaget had expected

143
Q

MacArthur-Bates Communicative Development Inventories

A

widely used battery of language questionnaires

144
Q

Institutional review boards (IRB)

A

ensure research participants do not experience harm as a result of their involvement and that they experience the potential benefits associated with experimental therapies or other treatments

145
Q

assent

A

the ability of children to indicate their own willingness to participate in research (research conducted with infants and young children often require the consent of at least one parent)

146
Q

difficulties surrounding experiments conducted on infants and children

A

researchers may experience issues associated with small sample sizes and homogeneous samples (samples of individuals who are similar to one another), which makes it difficult to generalize or apply their findings to other groups

147
Q

sally-anne task

A

a classic test used in developmental psychology to assess a child’s theory of mind, particularly their understanding of others’ beliefs. At 3 years old, children typically struggle with understanding false belief
