Pozzulo (psychology being investigated) Flashcards
Define line ups
- A form of evidence used by the legal system.
- In which a witness is shown a line of people/ photoarray of faces and is asked to identify the perpretrator.
Define eye witnesses testimony
- Legal evidence submitted by someone who has witnessed a crime take place.
- critical area in forensic psychology, particularly regarding the reliability and accuracy of eyewitness testimony
Define false postive response
Giving an affirmative but incorrect answer to a question.
Define false memeories
- A stored piece of information that an indiviudal belives to be an accurate memory but is actually a product of later, additional, untrue information.
How can memory become distorted?
- By information we are exposed to during and after encoding.
Problematic for eye witness testimonies (as human memeory is used as evidence)
Encoding
The process in which we initially recieve information
Storage
Maintaining this information overtime
Retrieval
Accessing the information when we need it.
Social factors
- Involves influences of social context and social pressures on decision-making.
- In a line up a child may feel compelled to make a choice even when uncertain. Due to perceived expectations from authority figures (or a desire to be helpful)
- And faced with a cognitively diffciult task the child will reply more on social factors (thus will make more mistakes)
police officers- authority figures
Cognitive demand
- Refer to mental processes involved in memory and recognition
- For instance, during a eyewitness identification, these cognitive factors include person’s ability to accurately recall and recognize faces or details from a memory.
Summarise the background simply
Pozzullo et al based the study on their previous research of child witnesses and they found:
* There are cognitive factors that cause errors in a child’s decision making process.
* There are social factors that cause errors in a childs decision making process.
* Children are more likley to identify an innocent person in an target-absent lines ups. (false postive responses)
When the culprit was not present in the line ups.
What are some cognitive factors that can influence a child’s decision making process? (during a line up)
- Post-event information (like the way a question is asked to the child)
- So any information they are exposed during or after encoding.
What are some social factors that can influence a child’s decision making?
Children are less likely than adults to say “ I dont know” :
* Children feel they must make a response. Saying a culprit is not there, is seen as a non-response.
* More likely to comply with authority figures
* Fear of getting into trouble
