Cognitive Approach Methodology

Pregunta	Respuesta
The cognitive approach believes that...	the mind dictates much of human behaviour
It's methodology is concerned with...	investigating the mind
Why does the cognitive approach use lab experiments?	Because they believe that psychology is a science so should be researched through the most scientific methods.
The cognitive approach believes that the mind can be influenced by...	observing human behaviour/asking leading questions.
An example of this is Loftus and Palmer who...	Investigated the effects of leading questions on memory through lab experiments.
From these experiments Loftus and Palmer were able to conclude that...	leading questions affect the accuracy of eye witness testimonies.
This is highly credible because Loftus and Palmer had high...	internal validity, as it was conducted in a lab setting.
Why do lab experiments have high internal validity?	As all extraneous variables are controlled for.
How do you mention police interviews in this essay?	Such credibility has meant that research has been able to impact society (e.g. has changed the way that police question witnesses). This does not just strengthen L+P, but of lab experiments used by the cognitive approach as a whole.
What is a weakness of using lab experiments?	They lack ecological validity, as the environment in which they take part is controlled and not like real life.
How can this be applied to Loftus and Palmer?	The inaccuracies found in Loftus' research may simply be due to the fact that the research was conducted in a lab.
Yuille and Cutshall can be used as an example of this. What did they find?	That eye witness testimony to a real life event were accurate four months after the event, regardless of two misleading questions.
What is the other method used by the cognitive approach?	Case Studies.

For example the case study of .... took place over ....	HM, over a 50 year period.
A strength of this method is...	that valuable information can be obtained that cannot be obtained through any other method.
What did HM support the idea of?	The Multi-store model of memory, and the idea that short-term memory and long-term memory are located separately.
A weakness of case studies is...	that findings lack generalisability, as the person used in the case study may be unique.
What are some other weaknesses of case studies?	Very time consuming and expensive to conduct the research, which limits the amount of research conducted.
What do these weaknesses do to the research overall?	The weaken the validity of the research.
