Developmental trajectory Flashcards

1
Q

Why is it important to study the predictor/outcome relations before interventions?

A

Need to understand the predictor as we need to see if it actually has an affect on development

Q

What is a strength and limitations of cross-sectional design?

A

Strength: more afforable
Limitation: Can’t make a strong inference
don’t allow for any inferences about stability
HOWEVER it gives a first look at change

Q

Murphy et al (1999): How did they measure emotionality and regulation? What was the age range? What was the result?

A

How: Parent-report
Age: 5-7
Result: Emotionality = intense emotions decrease

Q

In Lopez-Vicente et al (2016), what analysis did they do to account for variance? What did it tell us about the shape of change?

A

Multi-level modelling
For numbers, there is shown to be an increase and then levelling off
For words there is a linear continuous increase

Q

What is continuity in development?

A

Dev changes occur gradually and performance draws on similar processes

Q

What are the key points about studying change?

A

Change is mostly age-related
Cross-sectional data allows some identification of patterns
But Longitudinal data allows analysis of individual differences
Time sampling influences the shape of change
Allow us to infer how experience and factors shape development
change does not always imply discontinuity

Q

What did Hay & Forrest demonstrate about rank order and stability of self-control

A

Largest groups were the most stable
Those that were high in self-control would stay high
Identified rare patterns such as a high to decreasing group

20
Q

What did Fernald et al (2013) study for change and stability? what did the study show?

A

Socio-economic status and vocabulary for infants aged 18 and 24 months
Those that were in a higher SES had a steeper slope (therefore bigger increase in vocabulary)

21
Q

What are the key points about studying stability

A

Study how individual differences remain constant over time
Does not always imply continuity
requires detailed picture of individual diff across time
ID in one trait may predict another
Supports inferences and underlying processes

22
Q

What is an important challenge in the study of change and stability?

A

Measurement equivalence

23
Q

What does change and stability focus on both between and within individuals?

A

Variability

24
Q

What does change and stability focus on rather than time 1 vs time 2?

A

Trajectory, including shifts from stability to instability

25
What are periods of stability in performance?
A benchmark rather than endpoint
26
What are the 5 main methodological approaches associated with change and stability/developmental trajectories
Cross-sectional design Longitudinal Correlational Analysis of variance Modelling
27
What type of hypotheses do researchers use cross-sectional designs for?
age and experience related changes
28
Why would researchers use correlational analysis for change and stability?
identify coherent patterns of differences between people in longitudinal studies
29
What does Analysis of Variance do?
Can identify change across age in longitudinal studies; Considers the variance an individual contributes to the data at Tn to stay the same Focus is on the average change across age
30
What does multi-level modelling do?
Allows researchers to consider the differences between individuals as well as changes across time
31
When should you use longitudinal data?
Identifying stability
32
What is cross-sectional data useful for?
shaping design choices for longitudinal studies
33
What did Hendry et al (2022) study between infancy and toddlerhood?
Inhibitory Control (global, competitive and behavioural)
34
How did Hendry et al (2022) measure Inhibitory Control? What was the result of their study?
Global inhibition = toy prohibition task and touchscreen prohibition task Competitive inhibition = A-not-B task, ECITT Behavioural inhibition = Touch screen approach task Result; Progression for behavioural inhibition was clear from ages 10 to 16 months HOWEVER no evidence of longitudinal stability in individual differences in either prohibition tasks
35
What were the limitations of Hendry et al's (2022) study? How can it be improved?
Additional time points to give a clearer trajectory Behavioural inhibition questionnaires alongside task-converging methods Randomise ordering of tasks
36
What developmental trajectory did Hunt et al (2022) investigate?
Inhibitory Control and its association with symptoms of ADHD/ASD in young males with fragile X syndrome
37
What inhibitory control measures this Hunt et al (2022) use?
Rothbart Scales of Temperament - [Early] Childhood behaviour questionnaire
38
What was the result from Hunt et al's (2022) study?
Compared to neurotypical group, IC decreased at each time point for the Fragile X group Linear relationship between IC and age Differences in IC abilities exhibited at 24-36 months then widened across childhood
39
How could Hunt et al (2022) improve their study?
Look at the subtypes of IC have ADHD assessed by clinician Lab tasks to measure IC Questionnaires done by secondary informant eg teacher
40
What did Hosch et al (2022) study?
Development of self-regulation using 17 measures such as performance-based, questionnaires and raters
41
Why did Hosch et al (2022) use 17 different measures for self-regulation?
To account for heterotypic continuity I.e the behavioural manifestations of self-regulation change over time so one type of measurement won't be appropriate in a longitudinal design
42
What kind of design did Hosch et al (2022) use
Accelerated longitudinal design
43
What kind of tasks did the children undergo during the lab visits in Hosch et al's (2022) study?
Computerised tasks, go-no-go tasks, parent-child interaction tasks, self-reg tasks, assessments of achievement
44
What was the result of Hosch et al's (2022) study?
Shape of change ; positive quadratic slope (Showed rapid growth from ages 3-6 then levelled off ) Evidence of heterotypic continuity Girls had higher self-reg at 3 to boys but boys caught up by age 7
45
What were the limitations to Hosch et al's (2022) study?
Observational - can't make causal inferences Self-regulation is defined as a reflective(combination of several factors that are correlated together and thought to relate to self-regulation collectively) rather than a formative (several factors that may not correlate together but relate to self-regulation)
