Who produced the psychosexual stage theory?
Sigmund Freud
What is the psychosexual stage theory?
Stage-specific behaviours are driven by inner conflicts and result anxiety signals. Successive resolution of conflicts aid in progressive maturation.
Who proposed the Temperament theory?
Thomas, Chess and Kagan
Who proposed the Organismic theory?
Piaget
Who proposed the Attachment theory?
Bowlby
Who proposed Social Learning theory?
Bandura
Who proposed Psychosocial stage theory?
Erikson
Who proposed collaborative learning theory?
Vygotsky
Who proposed maturational growth theory?
Gesell
What is temperament theory?
Temperaments are inherent biologically based traits varying from difficult to easy (or inhibited to uninhibited). Temperament elicits environmental response that perpetuates a pattern of behaviour
What is organismic stage theory?
Development occurs in stages with transition occurring as a result of interaction of the child with its environment (child as a scientist)
What is attachment theory?
Innate tendency to seek relationships influence patterns of behaviours in later life
What is social learning theory?
Observational learning in childhood influences later behaviour
What is psychosocial stage theory?
Psychosocial developmental stages are characterised by conflicts, but the successful resolution is not mandatory for further development
What is collaborative learning theory?
Development is not entirely private; child acts as an apprentice in social surroundings rather than a scientist. Parents and teachers carry out the role of ‘scaffolding’ to introduce familiarity for the child to develop its own expertise (collaborative learning). Zone of proximal development refers to functions that are not yet fully achieved but are in the pipeline whose development is aided by scaffolding
What is maturational growth theory?
maturation of the nervous system as the principal driver of the various aspects of human behaviour
Stage-specific behaviours are driven by inner conflicts and result anxiety signals. Successive resolution of conflicts aid in progressive maturation. Name the theory and who proposed it.

What are the characteristics of Freud’s Phallic/Oedipal stage?
Genitals become organs of interest; masturbation-like activity noted. Oedipus complex - wish to have a libidinal relationship with the opposite sex parent (Electra complex in girls) with a desire to exclude the rival parent. This lead to a fear of retaliation from the rival parent in the form of castration anxiety in boys and loss of mother’s love in girls. Electra complex in girls include penis envy, a wish to have a penis is accompanied by blaming the mother for absence of a penis; later this becomes a secret wish to displace mother as object of father’s love and bear his baby. At the resolution of Oediupus and Electra complexes, identification with the aggressor (ie dad for boy and mum for girl) occurs; super-ego develops from introjection of parental values. Abraham divided this into the early partial genital (true phallic) and later mature genital phase.

What is a critical period?
a time point when an individual is acutely sensitive to the effects of external influences - both positive and negative
Name the three types of stress responsive seen in young children.
- Positive stress response
- Tolerable stress response
- Toxic stress response
Describe a positive stress response.
a brief, mild response moderated by the availability of a caring and responsive adult eg getting an immunisation or anxiety associated by the first day of school. When ‘buffered’ adequately positive stress responses are growth-promoting opportunities.
Describe a tolerable stress response.
associated with exposure to non-normative with a greater magnitude of adversity eg death of a family member or serious illness or injury. When buffered well the risk of physiological harm and long term consequences are greatly reduced
Describe a toxic stress response.
strong, frequent or prolonged activation of the body’s stress response in the absence of buffering protection from supportive adults eg child abuse, neglect, parental substance abuse and maternal depression. Toxic stress disrupts the developing brain circuitry during sensitive developmental periods forming precursors of later physical and mental illness
A brief, mild response moderated by the availability of a caring and responsive adult eg getting an immunisation or anxiety associated by the first day of school. Which type of stress response is this?
Positive
Associated with exposure to non-normative with a greater magnitude of adversity eg death of a family member or serious illness or injury. Which type of stress response is this?
Tolerable
Strong, frequent or prolonged activation of the body’s stress response in the absence of buffering protection from supportive adults eg child abuse, neglect, parental substance abuse and maternal depression. Which type of stress response is this?
Toxic
In a study children of different ages were compared on a given behaviour in order to determine age-specific developmental features. What type of study design is this?
Cross-sectional
In a study, the same children were studied twice over a prolonged period of time with respect to a single developmental feature. What type of study design is this?
Longitudinal
What is a mediator?
A mediator is a third variable which affects the relationship between a risk factor and an outcome (rather like a confounder) in developmental psychology - mediators are present in multivariate relationships and can be protective or buffers that reduce risk
Who proposed the Stress-Vulnerability Model?
Zubin and Spring
What is the Stress-Vulnerability Model?
mental illness is the result of two hits. The first hit is the vulnerability or predisposition of an individual that may be biologically or psychosocially determined. The second hit is the stress factor, which may act as a trigger or precipitant. This could be biological, psychological or social. Low vulnerable individuals will require high degrees of stress to develop an illness whereas highly vulnerable individuals may respond to hairline triggers.
What did Caspi et al (2003) show with regard to risk of depression, genetic factors and the Stress-Vulnerability model?
Individuals with one or two copies of the short allele of the 5-HT T promoter polymorphism exhibited more depressive symptoms, diagnosable depression, and suicidality in relation to stressful life events than individuals homozygous for the long allele
In Attachment theory (Bowlby), what is a primary caregiver?
A baby immediately needs someone to take care of them and a bond is formed, within minutes, between this first person and the child - this person is usually the mother, but can be father, sibling, nanny
What factors can disrupt the formation of bonding in attachment theory?
- Too many people in the room right after birth (Klaus, Kennell and Klaus)
- Late provision of ‘motherly’ care - after 30 mins
What is monotropy?
The innate tendency to attach to one adult female - most children have multiple attachments, but 50% have primary attachment to mother
Name the phases of Bowlby’s Attachment Theory and the chronological ages they correspond to?
- Preattachment (birth to 8-12 weeks)
- Indiscriminate (8-12 weeks to 6 months)
- Clear-cut attachment (6 to 24 months)
- Independence (after 24 months)
What is Bowlby’s Preattachment phase?
Baby orientates to its mother/primary caregiver
What is Bowlby’s Indiscriminate phase?
Allows strangers to handle, infants become attached to one or more persons in the environment
What is Bowlby’s Clear-cut attachment phase?
Preferential attachment, separation anxiety, object permanence, stranger anxiety. At the later part, weakened stranger anxiety; other attachment figures may also be present
What is Bowlby’s Independence phase?
The mother figure is seen as independent
Describe Harlow’s experiments.
Established the importance of contact comfort in developing mother infant bonding. Rhesus monkeys were separated from their mothers, which were replaced by either a cloth covered or wire covered surrogate. Infants preferred the cloth covered surrogate as it provided contact comfort.

Ainsworth’s experiments
What are the seven situations in Ainsworth’s experiment/strange situation test?
- Mother and infant enter room
- Stranger enters room
- Mother leaves, infant and stranger in room
- Mother returns, stranger leaves
- Mother leaves, infant left alone
- Stranger comes back, tries to comfort child
- Mother enters and comforts child, stranger leaves
What are the classifications of infant behaviour in Ainsworth’s experiments/Strange situation test?
- Type A (Anxious avoidant)
- Type B (Secure)
- Type C (Anxious resistant)
Describe Type A infant behaviour. What percentage of children show this behaviour?
Anxious avoidant (15%). Indifferent attitude to mother leaving the room or entering the room; keeps playing indifferent to mother’s presence. Distress when alone, not when mother is leaving. Stranger can comfort the child easily. Highly environment directed, low attachment behaviour.
Describe Type B infant behaviour. What percentage of children show this behaviour?
Secure (70%). Plays independently when the mother is in the vicinity (secure base effect). Distress when the mother is leaving; seeks contact on return of the mother and gets quickly comforted by the mother, not a stranger.
Describe Type C infant behaviour. What percentage of children show this behaviour?
Anxious resistant (15%). Fussy and cries a lot and cannot use mother as a secure base to explore around. Very high levels of distress are seen when the mother is leaving, but not comforted easily on her return, appearing ambivalent about her return. Active resistance to stranger’s efforts to pacify. Highly caregiver directed low play behaviour.

Describe the fourth type of behaviour that is uncommon in the Ainsworth experiments.
Type D - disorganised. This is seen in maltreated or maternally deprived children. Child has an insecure, dazed look and acts as if it is frightened of the mother. This pattern may be a precursor to later personality difficulties or dissociative experiences. Mother may have experience of being abused as a child.
Who devised the Adult Attachment Interview?
Main
What is the Adult Attachment Interview (AAI) (Main)?
A fifteen item semi-structured interview based on the fact that infantile attachment patterns can be predicted reasonably accurately using discourse analysis of adults when recollecting their childhood.
What are the four patterns of behaviour that are outcomes from the Adult Attachment Interview (AAI)?
- Secure Autonomous - those who had a secure attachment provide spontaneous and coherent answers with the ability to talk freely about negative experiences in childhood (Type B Ainsworth)
- Dismissing of experiences - those who had an avoidant (insecure) pattern, often minimise their experiences, do not elaborate on them and do not use colourful metaphors during the discourse (Type A)
- Entangled - those who had insecure but ambivalent (enmeshed) attachment use multiple emotionally laden responses and ramble excessively (Type C)
- Unresolved disorganised - broken continuity and interruption in the logical flow of thoughts (Type D)
What is anaclitic depression (Spitz)?
When a child is hospitalised, a period of separation from primary caregiver occurs. Loss of this loved one is termed anaclitic (object loss) depression. It is counterproductive to development, but recovery is good if separation is kept to a minimum. Some improvement is seen with surrogate mothering.
Who proposed separation-individuation theory?
Margaret Mahler
What is separation-individuation theory?
the development of a sense of identity in young children, independent of their mothers
