L1- Methods In Developmental Research

What are the main aims of developmental research?

To describe and explain developmental change and uncover the earliest instances of knowledge.

What is the difference between competence and performance in cognitive tasks?

Competence refers to conceptual understanding, while performance involves cognitive skills needed to express that understanding.

What is a cross-sectional design in developmental research?

A study that compares different age groups at a single time point to assess behavior on the same task.

What are two advantages of cross-sectional designs?

They are time and cost-efficient and provide quick insights into similarities and differences between age groups.

What is a limitation of cross-sectional designs?

They do not provide insights into the processes of development, only snapshots of different age groups.

What is a longitudinal design?

A study that examines the same group of children over multiple time points to observe changes in behavior or abilities.

What is one use of longitudinal design?

To observe change over time within individuals and examine the stability of behaviors.

What is a disadvantage of longitudinal studies?

They are resource-intensive and may suffer from subject attrition (refers to the loss of participants over time, where individuals drop out, become unreachable, or die before the study ends ) or practice effects (improvements in cognitive test performance during longitudinal studies caused by familiarity, repetition, or memory of test items rather than genuine cognitive improvement. These effects can lead to overestimation of performance)

What is a microgenetic design?

A study that provides an in-depth depiction of change processes by observing children on the verge of a developmental change repeatedly over a short period.

What is the purpose of using different dependent measures in developmental research?

To reveal different levels of knowledge, such as explicit and implicit knowledge.

What is explicit knowledge?

Knowledge that is easily accessible to the child and can be measured through verbal responses.

What is implicit knowledge?

Knowledge that the child is unaware of, measured through spontaneous responses like gestures.

How can gestures indicate knowledge in children?

Gestures can demonstrate partial knowledge that may not be expressed in speech, indicating transitional knowledge.

What is the significance of the gesture-speech mismatch?

It shows that information conveyed in gestures may not appear in accompanying speech, revealing deeper understanding.

At what age do children typically begin to show knowledge through gestures?

At age 2, children may fail verbally but show knowledge through gestures.

What is the role of eye-tracking paradigms in developmental research?

They help examine implicit vs. explicit levels of knowledge in children.

What does the phrase 'absence of evidence does not equal evidence of absence' imply in developmental research?

A lack of evidence in a study does not necessarily mean that a child's knowledge or competence does not exist.

What is the goal of critically reviewing methodological adequacy in developmental studies?

To ensure that research methods effectively measure and reflect developmental changes.

What is one challenge in interpreting cross-sectional studies?

They may lead to the appearance of developmental stages without understanding the underlying processes.

What is a common research question suitable for cross-sectional design?

Does children's verbal recall capacity increase with age?

What is a common research question suitable for longitudinal design?

How does children's math anxiety predict their math achievement over time?

What is 'temporal primacy' in longitudinal studies?

It refers to determining which variable is antecedent( This is a variable that occurs before the main independent variable (the behavior or development being studied) and helps explain it. It is the "trigger" or early factor (e.g., early literacy exposure in infancy). and which is consequent (This is an event or outcome that occurs after the behavior, acting as a response or result e.g., school reading performance in third grade) in developmental trajectories.

What is the importance of considering age when designing a longitudinal study?

Age helps identify appropriate time points for testing and understanding developmental changes.

What is the significance of studying children on the verge of developmental change?

It allows researchers to capture the dynamics of change as it occurs in real-time.

How can longitudinal studies help in predicting later abilities?

They can identify early predictors of later abilities or behaviors, establishing developmental trajectories.

What is the most common way to measure infants' knowledge without verbal responses?

Relying on their looking behavior.

What does the preferential looking method aim to determine?

If infants can distinguish between different visual stimuli and if they have an attentional preference.

What does it indicate if infants look longer at one stimulus over another in preferential looking?

They can discriminate between the stimuli and find one more interesting.

What is a limitation of the preferential looking method?

If infants look equally at both stimuli, it is unclear whether they cannot discriminate or find both equally interesting.

What is the aim of the habituation/dishabituation method?

To determine if infants can distinguish between different stimuli by measuring their looking time.

What happens during habituation in infants?

A stimulus is presented repeatedly until the infant's attention wanes.

What does increased looking time during dishabituation indicate?

The infant has recognized a novel stimulus and distinguished it from the old one.

What does the inter-modal preferential looking paradigm measure?

If infants can link stimuli across different modalities.

What outcome indicates that infants comprehend the link between verbal and visual stimuli?

Infants look longer at the matching visual stimulus.

What does the violation of expectancy method assess?

If infants have expectations about events in the world based on their experiences.

What indicates that an infant is surprised in the violation of expectancy method?

They look longer at events that are impossible or inconsistent with their expectations.

What does the anticipatory looking paradigm measure?

If infants can predict events before they occur.

What does pupil dilation in infants indicate?

Responses to cognitively demanding tasks, novel events, and emotional stimuli.

What is a potential issue with interpreting negative results in looking measures?

Negative results can be hard to interpret as they may indicate various possibilities.

What is the main focus of looking measures in infant research?

To understand perception and cognition in infants.

What does increased looking time over trials in the looking time method suggest?

Infants may be losing interest in the repeated stimulus.

What is the significance of the anticipatory looking paradigm compared to violation of expectancy?

Anticipatory looking relies on prediction, while violation of expectancy relies on reactive looking.

What does the term 'fussiness' refer to in the context of infant visual paradigms?

Infants' restlessness that can lead to participant loss in studies.

What is one of the controversies in infant looking measures?

The distinction between novelty preference and familiarity preference.

What is the purpose of measuring looking behavior in infants?

To gain insights into their cognitive development and understanding of the world.

What does the term 'dishabituation' refer to?

Increased looking time when a novel stimulus is presented after habituation.

What is the role of empirical evidence in explaining looking measures to parents?

To provide a scientific basis for the methods used in research.

What is a common challenge faced in interpreting looking behavior in infants?

Determining whether looking is an active information processing or merely a blank stare.

What is the significance of the references provided in the notes?

They offer foundational studies and insights into the methodologies used in infant research.

What is the aim of the looking time method?

To assess infants' ability to distinguish between different stimuli based on their looking behavior.

What does a decrease in looking time during habituation suggest?

The infant has become familiar with the stimulus and is losing interest.

What is a key factor in the anticipatory looking paradigm?

The direction of an infant's first look before an event occurs.
