This document summarizes a study on age as a determinant of inattentional blindness. The study involved showing 20 college students and 20 residents aged 19-75 a video known as the "Invisible Gorilla" test. The findings showed that older participants aged 40-50 were more prone to not noticing unexpected objects like a gorilla in the video. Younger participants aged 20-30 were generally not as prone to inattentional blindness, though some in that age group also failed to notice the gorilla. The conclusion is that older adults are more susceptible to inattentional blindness than younger adults.

1. RESEARCH
ON
AGE AS THE
DETERMINANT OF
INATTENTIONAL
BLINDNESS
By Maya

3. INATTENTIONAL BLINDNESS
1. Observers fail to notice a visual object or event
2. The object or event is fully visible and observers
readily see it if they are looking for it.
3. The failure to notice results from engagement of
attention on other aspects of the display and not from
aspects of the visual stimulus itself.
4. The object or the event is unexpected.

4. OBJECTIVE
1. Older people are more prone to Inattentional Blindness.
2. Younger people are not prone to Inattentional Blindness.

5. METHODS
1. Controlled Experiment
2.Sample Size:
The sample of study is 20 B.A 3rd year students and 20 M.V.R
residents where, 10 male and 30 female observers were from 19 to 75 years
of age group for the study.
3. Study Area:
The area of study was the 20 B.A 3rd year students of GGIC,
Battisputali and 20 simple residents from Harisiddhi, Lalitpur.

6. VIDEO USED IN THE
EXPERIMENT
The “Invisible Gorilla” video made by Simon and
Chabris was used. This is not a standard method. Here
the instructions are given in the video and with the
name, age, sex and profession the answers to the
questions from the video are done in a sheet of paper
which are to be submitted to the researcher. The video
if given below:

8. FINDINGS
1. There are altogether 24 observers that didn’t see the gorilla in the
video “The Invisible Gorilla.”
2. 16 observers were not able to see the gorilla in the video “The
Invisible Gorilla.”
3. 6 observers could count 15/15 basketball passes within the white
group in the video and even saw the Gorilla.
4. 8 observers could count 15/15 basketball passes within the white
group in the video and didn’t see the Gorilla.
5. 2 observers counted 16/15 basketball passes in the white group in
the video and saw the Gorilla.
6.1 observer counted 16/15 basketball passes within the white group
in the video and didn’t see the Gorilla.

9. CONCLUSION
Older people are more prone to Inattentional Blindness especially the
group 40-50.
Younger people with the age group of 20-30 are not prone to
inattentional Blindness.
But to the oppeosite, There was also a finding that the age group of
20-30 half were equally prone to Inattentional Blindness.
