Untitled Deck Flashcards
What was the main strength related to the experimental setting?
The experiment took place in a controlled lab environment, increasing internal validity.
Why is using a standardised lab environment a strength?
It ensures that all participants had similar experiences, reducing variability.
How was the dependent variable clearly operationalised?
The dependent variable was whether participants correctly identified or rejected faces in a line-up.
Why is having a clearly operationalised DV important?
It allows for precise measurement and easier analysis of results.
What kind of data did Pozzulo et al. collect?
Quantitative data, which made analysis straightforward and objective.
Why is quantitative data considered a strength?
It allows for statistical analysis and reduces subjectivity.
What steps did researchers take to control demand characteristics?
Instructions and lab conditions were consistent to minimise participants’ expectations or biases.
Why is controlling demand characteristics a strength?
It reduces the chance that participants’ responses were influenced by cues in the experiment.
How did the study demonstrate ethical practices with children?
Researchers obtained consent from guardians and emphasised the right to withdraw without penalty.
Why was obtaining consent and ensuring no harm important in this study?
It ensured ethical standards were maintained, especially when working with young children.
What methods were used to make children comfortable during the study?
Experimenters engaged in crafts with children before testing and wore friendly, professional-casual clothes.
Why did the experimenters wear professional-casual clothes?
Overly formal attire could create social pressure, affecting children’s responses.
What was a key ethical strength of the study?
It was child-friendly, with attention to comfort, consent, and the right to withdraw.
What was a major weakness regarding ecological validity?
The lab setting does not accurately replicate real-world conditions for eyewitness testimony.
Why might ecological validity be important in eyewitness studies?
In real cases, witnesses experience emotional stress, which wasn’t present in this experiment.
What was a potential weakness related to emotional involvement?
Participants were not emotionally involved as they would be in a real crime scenario, affecting results.
Why is the lack of emotional involvement a limitation?
Emotional factors in real crimes can impact memory and decision-making.
What is an ethical concern in Pozzulo et al.’s study?
Some participants were deceived about the true purpose of the experiment.
Why is deception considered an ethical weakness?
Deception can harm participants’ trust and raises ethical concerns, especially in sensitive studies.
What was the research design for comparing adults and children?
An independent measures design was used for this comparison.
What was the design used to compare line-up types?
A repeated measures design was used to compare identification and rejection line-ups.
Why is using an independent measures design beneficial in this study?
It reduces carry-over effects between age groups, as each age group only participates in one condition.
What was the purpose of using a repeated measures design for line-up type?
It allowed each participant to experience both target-present and target-absent line-ups.
What materials were used to present line-up targets?
Videos and photoarrays of cartoon and human faces.
