Questions and Answers

What is the main criticism of using looking-time as a measure in infant cognition research?

It is too subjective and varies significantly between researchers.

It does not capture emotional responses of infants.

It requires special equipment that is often unavailable.

It might detect novelty rather than expectation violations. (correct)

What method does Dunn & Bremner suggest for assessing infant cognition comprehensively?

Multimodal methods that include both physiological and behavioral measures. (correct)

Only observational studies focusing on parent-infant interaction.

Action-based tasks that engage infants actively.

A single behavioral measure to keep the study simple.

In the study by Kaiser (1985), what was observed about adults' predictions in motion trials?

Adults were always accurate regardless of the conditions.

Adults detected violations in motion trials but not in no-motion conditions. (correct)

Adults could predict outcomes without needing to see the motion.

Adults struggled to detect any violations in motion trials.

Study Notes

Strengths of Violation of Expectation (VoE) Studies

Baillargeon, 1985 (Drawbridge Study): Investigated object permanence in 5-month-olds, challenging Piaget's theory. Infants were habituated to a rotating screen.
- Method: Infants viewed a screen rotating 180 degrees.
- Possible Event: Screen rotated to reveal a hidden block, then reversed.
- Impossible Event: Screen rotated completely, seemingly passing through the block; Infants looked longer at this impossible event.
- Findings: Suggests infants understand object solidity and position.
- Strengths: Shows infant's mental representation of hidden objects, including position, height, and solidity. Demonstrates infants reason about object properties.
- Criticisms: Overreliance on looking time, which may reflect perceptual differences rather than genuine reasoning; early VoE study, methodology has improved since.
Baillargeon, 1987 (Soft/Hard Objects): Examined infants' understanding of physical properties (rigidity vs. flexibility).
- Method: Infants observed a screen compressing a soft object and rotating through a hard object.
- Possible Event: Screen compressing a soft object.
- Impossible Event: Screen rotating through a hard object without stopping.
- Findings: Infants looked longer at the impossible event, indicating awareness of physical differences.
- Strengths: Demonstrates infants' early physical reasoning about object properties.
- Criticisms: Possible novelty preference for the hard object could explain longer looking.
Luo, 2003 (Reasoning About Hidden Objects): Improved VoE methodology to address earlier critiques.
- Method: Infants were familiarized with thin or thick boxes hidden behind a screen. A cylinder passed behind the screen.
- Possible Event: Cylinder passed behind a thin box
- Impossible Event: Cylinder passed behind a thick box.
- Findings: Infants looked longer at the impossible event, even with a 4-minute delay between familiarization and testing.
- Strengths: Demonstrates infants maintaining representations of hidden objects; reduced potential for novelty effects due to controlled conditions.
- Interpretation: Infants' surprise at spatial violations reflects an understanding of object solidity and space.

Limitations of VoE Studies

Schilling, 2000 (Familiarity Preference): Investigated how habituation influences test-trial preferences.
- Method: Four groups of 4- or 6-month-olds with varying habituation conditions (number of trials, etc.) were observed; Condition A to Condition D.
- Findings: Initial habituation influences test-trial outcomes, rather than physical principle violations.
- Critique: Familiarity and novelty preferences complicate the interpretation of VoE studies.
Haith, 1998 (Rich Interpretation and Perceptual Bias): Critique of VoE studies.
- Critique: VoE studies answer simple yes/no questions, lacking in understanding of the underlying mechanisms; long looking times may reflect perceptual salience or complexity instead of deeper reasoning.
- Example: Infants may notice a difference in an event (e.g., two objects encountering a surface), but not understand a deeper conceptual understanding like object permanence or solidity.
- Conclusion: VoE methods oversimplify complex cognitive phenomena.

Beyond VoE

Paulus, 2022 (Beyond VoE):
- Critique: Ambiguity; assumptions; construct validity. VoE often assumes cognitive abilities without fully exploring alternative explanations or considering other types of factors.
- Conclusion: Encourages expanding on VoE by combining it with both physiological and behavioral measures (e.g., social cues) to more fully understand infant cognition.
Dunn & Bremner, 2017 (Social Looking): Examined social cues in response to violations of expectations, finding that infants engaged in social looking during VoE trials but not in novel trials.
Kaiser, 1985 (Curved Tube Problem): Demonstrated looking time data reveals recognition of violations in motion trials, but not necessarily full predictive understanding.
Willatts, 1997 (Action-Based Tasks): Critiques VoE's reliance on passive observation; action-based tasks are crucial for determining infant's ability to predict outcomes.
