Exam Revision Flashcards
What did Gottlieb (1992) believe about methodology?
Multi-Level Systems Model
- development is subject to bidirectional influences over 4 levels of analysis
1) Genetic Activity, 2) Neural Activity, 3) Behavioural, 4) Environmental
What are Sensitive Periods?
An organism is particularly susceptible to experience different things during specific periods of development
- Explanation = brain maturation/plasticity or specialised
Example = Romanian Adoptees adopted before 6 months had most optimal outcome than those adopted after
What are the 4 basic goals of understanding development or change?
Describe, Explain, Predict, Influence
Fenson et al 1994 is an example of Cross-Sectional research, what did they find?
Rapid growth in No of words in a sentence as age increased, sig dif in sex
Wood et al 2012 is an example of Longitudinal research, what did they find?
- Autoregressive pathways of absenteeism and psychopathy which increased over time
- Cross-lagged pathways = existence of one increased the likelihood of the other in the future
What are the 5 key goals of Longitudinal research?
1) Consider change in individuals
2) Look at difference between individuals
3) Consider factors which drive change
4) look at causes of change within individuals
5) investigate causes of change
What is microgenetic measures?
Examines change as they occur
- Small samples but dense data collection
- Provides valuable info about changes as they occur
What are some challenges for Developmental Research?
- Developing measures which are reliable and valid
- Representative samples
- Reporting issues
- Objective Measures e.g. Brain Function = fMRI, PET, EEG Physiological = HR, Cortisol
Define Homo/Heterozygous Pairs
Homozygous Pair = two sets of instructions are the same at any given locus
Heterozygous Pair = two sets of instructions are different at any given locus
What is the First Stage of Pregnancy?
Germinal
- Zygote
- From Conception to Implantation
- Blastocyst = division into 2 sections approx 4 days after conception
- 1 section becomes the baby and the other becomes various structures to support development
What is the Second Stage of Pregnancy?
Embryonic
- After Implantation
- Forms foundation of all body organs
- All major organs and systems start to develop (organogenesis) e.g. Heartbeat starts at 4 weeks gestation
- Finishes at 8 weeks after conception
- Rapid development and particularly susceptible to environmental adversity
What is the Third Stage of Pregnancy?
Foetal
- 9-38 weeks
- Basic stuctures are refined and grown to final form
- Foetus grows approx from 1 inch and 1/4 lb to 20 inches and 7-9 lb
- Week 12 = sex
- Viability possible by week 22/23
Describe PreNatal development of the Brain
1st Month = Neural tune
6th Month = Most brain neurons are in place and synaptogenesis begins
Last Trimester = cerebral cortex
- Associated with new behavioural capacities
Describe Key Elements of Brain Development in Early Life
- Mature at different times
- Higher Cog funtions develop later
- Hippocampus, Amygdala and Corpus Callosum undergo rapid growth during first 3-5 years of life; implying the brain is susceptible to early life experiences
- Rapid increase in weight in M and W between 1-3 then weight generally plateus but men average higher
Describe Foetal Development
- Movement = 8 weeks onwards but Carrier feels it between 18-20
- Behaviour becomes more organised with gestational age e.g. at 34 weeks pattern of rest and activity
- 20% of the time spent in motionless, quiet sleep like state with steady HB and breathing
- The other 80% spent in Active-Sleep = movement, irregular HB/Breathing, responds to sensory stimuli
- 38 weeks = less time in Active-Sleep, more inhibitory pathways
- Activity and Rest periods alternate cyclically
Describe Foetal Behaviour Learning
- 25th Week onwards = changes in HR, moves head
- 32nd Week = distinguish between familiar and novel stimuli
- Decasper and Pence 1986 = prenatal learning is retained after birth as familiar stories preferred
What are Genetic/Chromosonal Prenatal Risks?
Autosomnal Disorders
1) Dominant Genes
- single abnormal gene e.g. Migraines, Huntingtons, Schizophrenia?
2) Recessive Genes
- mutation of both genes in the pair e.g. PKU, Sickle Cell Anaemia, Tay-Sachs
What are External Prenatal Risks?
Teratogenic
1) Smoking = birth weight
2) Alcohol = Foetal Alcohol Syndrome, 1-2/1000, small size brain, hyperactivity, anxiety, physical abnormalities
3) Drug Abuse = poor blood flow to placenta, born with signs of addiction, interaction effects e.g. early birth, poor nutrition
4) Maternal Stress = O’Conner er al 2002-03 = increased odds of behavioural and emotional problems persisting to 7 years old
What are the issues relating to Premature / Low Birth Weight?
- Increased risk for perceptual, attentional, motor, intellectual and behavioural impairments
- Gross to minor abnormalities
- Respiration Difficulty
- Difficult Deliveries
- High quality of care can moderate potential adverse effects
Definitions of Prematurity
Full Term = 38-42 weeks, 3150g, 53cm
Preterm = Less than 38 weeks
Very Preterm = Less than 32 weeks, 1700g
Extremely Preterm = Less than 26 weeks, 700g
Definitions of Birthweight
Optimal = 3/5000g or 6.6-11lb
Low BW = Less than 2500g or 5.5lb
Very Low BW = Less than 1500g or 3.3lb
Extremely Low BW = Less than 1000 grams or 2.2lb
(Grunau et al 2004 = ELBW at risk of developing artihmetic problems mainly, but also reading and spelling)
Facts about Vulnerabilities and Resilience in Pregnancies
- Most deliveries are normal
- 10% of all birth at risk of disability
- Develop resilience through brain plasticity and good environmental characteristics such as good caregivers, income, resources, child characteristics, community, neighbourhood
Describe the Visual Ability / Development of a newborn?
- Least developed of all senses
- Respond to light and track movement with eyes
- Visual Acquity is about 1/30th of perfect adult acquity
- Initial poor control over eyes (accomodation, focus both eyes on a spot around 8-10 inches)
- Show a preference for the mother’s face
- Demonstrate size/shape constancy
- Aislin 1987 = 6 weeks eye tracking is very jerky but by 10 weeks is smoother and constant
- Maurer and Salapatek 1976 = as we develop, focus on more important parts of the face i.e. Young = chin as this shows most movement
Describe Perceptual Skills in the first few months
First 2 months = first focus on where objects are, scan for light/dark contrasts, look for motion
2/3 Months = shift to what an object is, larger degree of detail noticeable, pay attention to patterns
What are the ways of studying Infant Perception?
1) Visual Preference
- measure how long a baby looks at 2 pictures (Fantz 1958) and preference implies discrimination
2) Habituation
- presenting 1 picture over and over until bored to see if there is a renewed interest
- implies visual memory
Describe Fantz’s studies on infant perception
Fantz et al 1960s = 2 day old infants discriminate between patterned and unpatterned stimuli
Fantz and Miranda = 1 week old infants show a preference for curvy shapes rather than straight
Fantz and Fagan = 2 months infants prefer more complex patterns suggesting improved visual acquity results in greater interest
What research is there on Face Perception
One of the most important stimuli and is advantageous for survival and learning
- Langois et al 1990/1991 = prefer attractive faces
- Walton et al 1992 = prefer mothers face from birth (sucked dummy more)
- Pascalis et al 1998 = no discrimination is hairline covered
- Sai 2003 = recognition of mother’s voice turns attention to face
- Simion et al 2001 = babies prefer up-down asymmetery and congruency as it is more similar to human faces
- Turati 2004 = schematic analysis found faces important for development
- Johnson et al 1991 = babies less than an hour old tracked faces better than scrambled/blank faces
- Meltzoff and Moore 1977 = 12-21 days old can imitate facial expressions
What mechanism may account for Face Preference?
- Faces display stimulus characteristics that are inherently appealing such as high contrast, top heavy, move, dynamic
- Morton and Johnson 1991 = we are born with “innate face detecting” brain mechanism that directs attention specifically to face-like recognition
- Despite the different accounts, all suggested mechanisms ensure that newborns attend to faces and this visual input helps the development of an increasingly sophisticated face-processing system
Describe Adolf’s Work on the Visual Cliff
Campos et al 1992
- HR difference in those who could / could not crawl
- Learning not to move onto the cliff was gained via experiences with crawling
- Experiences in walkers linked to showing fear in response to depth in infants who cannot
Even though not showing fear change in HR acknowledges some form of depth perception in early age and independent of locomotion
How does Auditory Perception develop?
Focus on the voice/speech which one considered important for the development of attachment/language. Begins to develop before birth
- foetal reactions to sound from 20 weeks and a near term foetus can differentiate between male/female voices
- preference for mothers voice, especially how it would have sounded in the uterus
- prefer own language to others
- At 1 month can distinguish between “ba” and “pa” sounds
- At 6 months can discriminate between 2 syllables
- Up to 6 months = discriminate all sound contrasts that appear in all languages, but this ability disappears by 12 months, corresponds to rapid pre-programmed growth of synapses followed by synaptic pruning
How do the other senses develop?
Steiner 1979 = newborns respond differently to basic tastes
Rattaz et al 2005 = 1 week old can distinguish body odour of mother and stranger
Touch/motion is one of the most sophisticated senses at birth and is fine tuned during the first year
Explain Intersensory Integration
How early can infants integrate sensory info across more than 1 modality to perceive it as one event e.g. matching mouth movements to sound
- Spelke 1979 = 4 months connect rhythms with movement
- Pickens 1994 = 5 months connect sound and sight in motion
Define Cross Modal (Intermodal) Transfer
How early can an infant learn something via one sense and transfer that info to another sense e.g. recognise a toy by touch although it has only been seen before
What are the basic emotions?
Experienced/expressed by all humans and each comprimises of differentiable, distinct feature e.g. facial expressions, physiological patterns and subjective feelings
- Happiness, Anger, Fear, Surprise, Sadness, Disgust
What are Complex/Dependent emotions?
Dependant on interactions between affective and cognitive processes and influenced by experience, learning and socialisation
- Guilt, Shame
What is Dynamic Systems Theory? (Buss et al 2019)
In a dynamic system, components influence and change each other via the process of self-organisation
- For most, the result of self-organisation is more flexible, efficient was of functioning
- The outcomes of self-organisation are called attractor states = emotions/mood/personality
- For example, emotion comprises of different components like facial expressions, physiological behaviour, instrumental behaviour, subjective experiences which all develop independently with different trajectories but come together in different contexts
What did Ekmen and Friesen (1971) find when looking at facial expressions?
Studied people living in New Guinea who were unexposed to Western Media and had them identify correct emotional response to a story
- Child = all sig results
- Adult = highly sig results, had difficulties distinguishing fear and surprise
What does the research conclude on facial expressions and the blind community?
Valente and Gentaz 2017 = blind and seeing athletes gave the same facial expressions after losing a match
- Congenitally blind people can produce similar spontaneous emotional facial expressions to seeing people, but have trouble producing voluntary emotional expressions
What did Hata et al (2013) work on emotional expression and foetuses conclude?
- No invariant linkage between emotional expression and emotion in unborn foetuses
- Foetuses produce a variety of facial expressions including smiles and pain expressions in non-painful ultrasounds
- Findings for prenatal facial expressions align with a dynamic systems view of emotional development
What did Bennet et al (2002) find when looking at emotional stimuli responses?
Gave a 4 month old a stimuli which elicits a responses e.g. tickle = joy, jack-in-a-box = surprise, masked stranger = fear
- Only Joy and Surprise had the correct most common emotion e.g. disgust = sadness and anger, Fear = surprise
- Little support for dynamic emotion theory of situation specificity
Define a timeline of emotional responses in childhood
0-2 months = Smile in Sleep (Dandi et al 2007)
2 months = Social Smile
2-6 months = Interactive Smiling (Messinger et al 2010)
6-18 months = Referential Smiling
Across Childhood = specific use of Duchenne Smiles in social success
Describe White et al (2018) study on emotion recognition in infants
- Four emotion contrasts = sadness/disgust, sadness/anger, anger/disgust, happiness/surprise
- Examination of within valence contrasts
- Across Boundary = 40% vs 60%
- Within Boundary = 20%/80% vs 40%/60%, compare emotions on one side of the scale but different levels
- Exp 1 results = sig for sadness/disgust and happiness/surprise but not the other 2
- Exp 2 results = habituated children to 60% faces of 1 emotion then showed a face which crossed the border soent more time looking at the newer face but not for anger/disgust
What did Pons et al 2004 find when looking at emotional recognition across development?
Facial expression recognition reached adult levels by 11 years old
- Vocal emotion recognition continues to develop inter late childhood/adulthood
- implications for programmes aiming to improve child’s socio-emotional competence
What did Vaish and Striano (2004) find when looking at encouragement and the visual cliff?
Vocal info was important and more impactful than face, as those who did cross in voice only crossed much faster than face only
- Face + Voice = crossed the cliff drop, smiled, vocalised
- Face Only = faced the cliff, smiled, nodded
- Voice Only = did not face the cliff, continued watching TV, vocalised
What are the Emotional Components?
I) Recognition = recognising/naming of emotional expressions
II) External Cause = understanding how external causes affect the emotions of another
III) Desire = emotional reactions depend on their desire
IV) Belief = a person’s belief determines their emotional reaction
V) Reminder = relationship between memory and emotion e.g. intensity decreases with time
VII) Regulation = behaviour strategies or psychological strategies
VII) Hiding = discrepency between expressed and felt emotion
VIII) Mixed = a person may have multiple or even contradictory emotions
IX) Morality = negative feelings from morally reprehensible situation or positive feelings for praiseworthy situation
How are the Emotion Components Affected by age?
Phase 1 = 5 year olds = Recognition, Reminder, External Cause = understanding of important public aspects of emotion
Phase 2 = 7 year olds = Desire, Belief, Hiding, Mixed = understanding of mentalisatic nature of emotions
Phase 3 = 9-11 = Regulation, Morality = understanding of multiple perceptions and regulation
What did Cavioni et al (2020) conclude about Emotion Comprehension?
Test of Emotion Comprehension used to investigate understanding of emotion
- Confirmatory Factor Analysis supported original psychometric structure based on 3 developmental domains
- External, Mental, Reflective
What is Cuff et al (2016) definition of empathy?
“emotional responses dependent upon the interaction between trait capacities and state influences. Empathetic processes are automatically elicited but are also shaped by top-down control processes. The resulting emotion is similar to perception and understanding of the stimulus emotion with recognition than the source of emotion is not one’s ….”
Describe Stern and Cassidy’s 2018 diagram of empathy
Parenting = sensitivity, empathy, socialisation
Attachment
Mechanisms = internal working models, parent/child discourse, emotional/self regulation capacities, neurbiology
Moderators = Individual (gender, temperament, genetics), Dyadic (socialisation, emotional cues), Group (membership, norms), Societal (culture, bioecological context)
Child Empathy
What are some examples for Emotion Regulation Strategies?
1) Attention Focus
2) Reappraisal
3) Suppression, Gullone et al 2010 = lower likelihood as age increases, most common in men
What did Cracco et al 2017 find in terms with age and emotion regulation strategies?
- Between 12-15, increase in maladaptive strategies e.g. giving up, withdrawal, rumination, self-destruction, aggressive actions
- And a decrease in adapative strategies e.g. problem solving, distraction, forgetting, acceptance, humour, re-evaluation
What did Zimmermann and Iwanski (2014) conclude about age and emotion strategies?
Measured 7 strats = adaptive emotion regulation, social support seeking, passivity, avoidant regulation, expressive suppression, dysfunctional ruminantion suppression
- Found age different in expressive suppression in sadness and fear, but not anger
- Stepwise increase for fear in early adolescence to adulthood but sadness fluctuates but maximum use in early adolescence
- 15 = least likely to use emotion regulation strats when experiencing sadness/anger in comparison to 11, 19 and adult groups
- Less strat used for fear in 13-15 in comparison to all age groups
- All adult groups had no sig dif in strat repetoire
- Post Hoc = passivity only appeared when feeling sad/angry (not fear), U shape for passivity and sadness between 11-25, decreased for fear from 11-25
Describe a timeline of language development
0 months = cooing
6 months = duplicated babbling e.g. “dadadada”
12 months = first word e.g. “dada”
2 Years = 2 word combo e.g. “daddy gone!”
3 Years = multi-word utterance e.g. “where has daddy gone?”
4-5 Years = questions, complex sentences, conversation
What does Language Development Require?
1) Comprehension
2) Production = phonology, semantics, grammar, pragmatics
What are Empiricist views of Language development?
1) Skinner 1957
- children are reinforced with gramatically correct speech
- adults shape child’s speech by selectively reinforcing babbling which sounds most like words
- once words have been shaped, reinforcement is witheld until child starts to combine words
2) Bandura 1971
- children listen and imitate language of older companions
- caregivers “teach” via modelling
What are Nativist views of Language development?
1) Chomsky
- Language Acquision Device = an inborn lingustic processor that is activated by verbal input and contains universal grammar
2) Slobin 1985
- Language-Making Capacity = a set of cognitive/perceptual abilities that are highly specialised for language learning
What are Interactionist views of Language development?
- Complex interplay between bio maturation, cog development and lingusitic environment
- Children across the world develop language at a similar pace as we are all from the same species and have similar experiences
- Children are biologically prepared to learn language as they have a brain that matures slowly, which gives children more to talk about
- Language develops to communicate with other people
What areas facilitate language development?
Left Hemisphere = damage can cause aphasia
- Brocca’s area = production
- Wernicke’s area = comprehension
Genie = had no language development due to no communication as a child and being punished if tried. When later taught language at 13, she was incapable signifying a sensitive period.
- Johnson and Newport 1989 = immigrants who moved to the US when 3-7 spoke as well as natives but this decreased with age
How does experience effect language development?
Child-Directed Speech (Stern, 1990)
- close proximity, exaggerated facial expressions, repetition, eye contact, higher pitched voice
- natural in most cultures
- gradually increase length and complexity
Non-verbal games help teach turn taking
Describe the PreLinguistic Phase?
DeCasper and Spence 1986
- children start to process sounds in the womb
1-2 month = discriminate between different phaemes
Werker and Tees 2005
- across different languages
- neural commitment
- 6-8 months are able to discriminate similarly Hindi/Salish words but this skill drops with age
How do we prepare for Speech Production?
- Different patterns of crying, increasingly social in nature
- From 1 month = begin to coo making repetitive vowel sounds signalling pleasure, proto-conversation with mothers talking after child to signal turn taking (Bateson 1975), evolves into triadic interactions when infants point to objects
1) Proto-Imperative = request for an object/action
2) Proto-Declarative = comment on an object/act
Research on First Words
- Receptive language is evident before expressive
- Fenson 1994 = 10 months/30 words but 13 months/100 words
- Bergelson and Swingley 2012 = infants begin associating highly familiar words with references surprisingly early e.g. 6-9 months knew meanings of common nouns but parent’s didn’t realise
- Learning is constraint = whole object constraint, mutually exclusive constraint, Mather and Plunkett 2010 = correlation of more general constraints and attention/learning
- OR children construct a “semantic system” because words are related to one another = facilitated by acquisitions of relations, learn that objects can be referred to as more than 1 word and how words related to one another e.g. opposites, synonyms
- Condense Meaning = Holophrase Period (12-18 months) and Overextension
- Goldfield and Reznick 1990 = verbal spurt at 16-24 months
- Nelson 1973 = over 50% of the first 50 words you learn are general nominations, then specific meanings, then actions
What are Facilitators of Vocab Spurt
Parents/Experiences
- Label/stress/repeat new words
- Playing naming games
- New words depending on context
- Spatial Consistency = learn label quicker in same location
Children
- Fast Mapping = process of rapidly learning new words from context
- Pragmatic cues
- Inferring meaning by taking cues from linguistic context and synaptic bootstrapping
- Cross situational word learning with repeated correspondance
Describe the development of Grammar
Fenson et al 1994 = very strong correlation between vocab size and complexity of sentences
2-3 years = less telegrahic speech (shot, simple, grammar errors), add inflections (e.g. ing to verbs), form Qs, may create forms of words which they have not heard but follow their understanding of grammar e.g. overregularisations = applying basic rules to irregular words e.g. goed or broked
3-4 = form complex sentences using conjunctions and embedded clauses
4+ = further refinements
