PROCEDURE
Each video tape included 2 teams of 3 players and members moved randomly whilst playing basketball in a set order.
After the task, pps were asked to write down how many passes they witnessed and then asked questions about the gorilla/women
They were also asked if they had taken part in a similar study or had heard of this phenomenon; if they had then their results were removed. Participants were then debriefed.
CONCLUSIONS
Individuals do have inattentional blindness for dymanic events. he extent of this is based on the difficulty of the primary task
-
VALIDITY
High design validity because of control over extraneous variables, however demand characteristics could've influenced pp's
High ecological validity - however they were watching a video, not in a real life situation
High concurrent validity between the findings with the computer based studies and Neissers earlier umbrella women video.
RELIABILITY
Highly controlled lab experiment makes it replicable, and the study had consistent findings.
Some participants were not included and lowered the reliability, not like real life, unreal situations.
DATA TYPE
Collected quantitative data by collecting percentages who noticed the unexpected event. This allowed for comparisons
The study included no qualitative data so there was no information on people’s reasons for why they did or didn’t see it.

ETHNOCENTRISM
Everyone can use attention, however it only looked at undergrad students who may live a different lifestyle to others, and attention can also change with culture.
There were no ethical concerns with this study. Informed consent was gained before the study and participants were debriefed at the end, where the video was replayed to them to prove the unexpected event had indeed occurred.
