Cognitive Area Evaluation Flashcards
What are the two assumptions of the cognitive area
1) looks at mental processes such as attention, perception and memory and how they affect human behaviour
For example, Loftus and Palmer looked at how leading questions distort memory of a car crash.
2) Computer analogy
We input info via our senses, process by storing and retrieving.
We output info in the form of behaviour or an emotional response
Give similarities between loftus and palmer and grant et al
=Both collected quantitative data
L&P = participants speed estimates + whether they report seeing broken glass
G = no. of correct answers on recall and recognition test
=Both used independent measures design
L&P = different groups heard different verb in critical question
Grant = four different groups of participants who read and recall article in matching conditions or mismatching conditions
= Both used same research method (lab experiment)
=Both used opportunity sampling
(Grant- friends of psychology students)
Give differences between Loftus and Palmer and Grant et al
Loftus Paler less ethical than Grant
= L&P didn’t gain informed consent +decieved about leading questions and not aware of aim of the study
= Grant did gain informed consent as they knew study was looking at memory
Different applications
L&P suggests police should be trained to not give leading questions as it can distort witness memory
Grant = revision should be done in matching context to the exam eg. silence
Give similarities between Moray’ study and Simon and Chabri’s study
type of design - both used LABORATORY EXPERIMENTS
=in experiment 2 Moray manipulated IV (whether participants were given an instruction to change ears with their name or not) and it was done under controlled conditions
= IV was manipulated under controlled conditions
type of data - both had QUANTITATIVE DATA
= moray recorded no. of words recognised, whether they changed ears when told to, no. of digits recalled
= simon and chabris recorded whether or not participants recognised the unexpected event
Give differences between moray’s study and simon and chabris study
DIFFERENT EXPERIMENTAL DESIGN
= moray used repeated measures design in experiment 1 as participants shadowed a message in one ear while rejecting the message in the other
= Simon and Chabris used independent measures design as different groups watched a video with either gorilla or umbrella as the unexpected event
Give strengths of the cognitive area
good scientific status
= good controls
= standardised procedures
applications to real life
= understanding how we process info has application
= loftus and palmer on reconstructive memories changed how criminal justice system deals with eye-witness testimony
less ethical issues
= grant et al had no ethical issues
=
Give weaknesses of cognitive area
Computer analogy has weaknesses
= human mind does not process information like a computer
= peoples behaviour isn’t always logical : we are affected by emotions, intuitions and instincts
Cognitive reductionism
=focuses on mental processes and ignores how multiple factors interact to affect human behaviour
How does cognitive area support psychology as a science
MANIPULATION OF VARIABLES
= loftus and palmer manipulated IV the verb in the critical question, measured DV, speed estimates, under controlled conditions
QUANTITATIVE DATA
= Simon and chabris collected no. of participants who noticed the unexpected event in each condition , objective and can be statisticallt analysed
CONTROLS
= loftus and palmer, all watched same film clips
= moray, all wore headphones
CAUSE AND EFFECT
= grant et al manipulated IV (matching vs mismatching context) and measured DV (recall and recognition) under controlled conditions ( all wore headphones and read the same psychoimmunology article)
REPLICABILITY
= standardised procedures
= all read same immunology article and given same short-answer questions and multiple choice questions
Similarities between milgram and bocchiaro
SAMPLING - self selected
= milgram used advert in newspaper and direct mail
= bocchiaro used flyers around the uni
Differences between milgram and bocchiaro
Milgram less ethical
= had high levels of distress
= many upset & 2 had seizures
= given verbal prods
Bocchiaro
= participants protected from harm
= low stress situation (write statement)
= left alone to decide whether to obey or not rather than verbal prods
