Research Proposal - Using lighting to change our behaviour

During Semester One we were asked to read 'The Tipping Point' by Malcom Gladwell. We then had to choose one of the theory's in the book that we found the most interesting and research it further. I chose 'The Power of Context' looking at how humans interact with there surroundings, and the influence changing our surroundings can have on our behaviour. As this is a huge topic I decided to focus on a single aspect of our built environment, Lighting.


Through my initial research I learnt that lighting can be used to  influence our behaviour in many different ways. It can make us  feel safe and more secure in potentially dangerous  areas such as subway tunnels, or in public toilets bright coloured light can make us fearful and anxious, making us evacuate the space as soon as possible. Lighting's ability to  subconsciously direct us through spaces and keep us aware of our environment is what I will be investigating  in my research proposal. I want to find out how we could optimise a space for humans to get the maximum use out of it, using light. 



The research methods I will use will be experiment based, alongside observation and an interview to collect information.
A feasible location to carry out the experiment would be a university library, more specifically a study zone within a library where good  lighting is essential, and there are a large amount of people present and who use it frequently. I have noticed from my own experiences and from talking to others that have used a study zone that it is very easy to become distracted, and/or begin people watching. I feel that the bright overhead lighting often found in these study zones may contribute to this distraction. Because we are seeing everything in bright light movements in the space can be easily picked up by our peripheral vision. These movements could be anything, even someone bobbing there head to music is enough to distract some people. 

The experiment I propose to carry out will help me to gather information on levels of distraction within the library setting and see how much of it is linked to having the brighter lights. 
In preparation for this I would look to take a small section of the study zone and slightly dim the overhead lighting in that area, If there was no dimming option for the lighting, I would look to place a suitable dulling material over the lights. I would then equip all the study desks in the area with there own personal lamps.
 I will then observe and note the distraction levels of students, first with the library lights at there normal strength, and then again after dulling the lights.(Possibly on a different day) The distractions I would be looking for would be things that could be seen in bright light, but not when the light is dimmed.


Alongside my observations, I would ask a small selection of students to spend some time studying in the library when the lights were at there usual level of brightness, and again when I had dimmed them, I would then carry out a quick semi-structured  interview with them, questioning how well they felt there studying went at both periods. 
I would include questions like:

In which of your study sessions did you feel the most focused ?


In which study session were you the most productive?


Did you find  working in a dimmer light had any negative aspects?


Did you find working in bright light has any negative aspects?


What level of lighting would you like to prefer to use in the future?


Using both an interview and observing/recording, would allow me to gather a broader selection of information to work with.
Observation would allow me to record the causes of the students distractions, and determine weather they would still be apparent in weaker light conditions. This would then give me an overall impression from which I could take a general conclusion. The interviews will allow me to gather more in depth information, adopting a semi - structured approach and leaving questions open would allow students to elaborate on there answers, providing useful personal  information about there studying  experience during the experiment.
I would look to carry out the experiment over a couple of days, recording for a few hours at a time, during different times of the day this would give me wide enough selection of students and changing  light conditions to draw a general conclusion. I would ask for another person to help observe from a different position as this would allow a wider area to be covered, and provide more even results.


Working through the design process ,the information  gathered from this experiment would hopefully provide a building block to work from and ideas could then start to be formed about potential solutions.One possible solution  could be designing the lighting  in a way to allow for safe navigation of the space, but subtle enough to not illuminate everything, then individual task lights would illuminate only the area that the student was working on.(similar to the individual task lights on an aeroplane)

Assignment 4 - How much of an affect does lighting have on the way we experience a space?

I have decided to look at lighting again for this assignment, and research how much of an effect it has on us in certain environments. I will be taking a different approach to my research this time, as we have been asked to prepare and carry out an interview with a small number of people.

-Preparing the interview questions.

In order to find out what questions I wanted to ask I  started a mind map looking at lighting in different situations, and what effect it has within these situations. For example; Lighting in a cinema lobby is usually dimmed to create a more intimate atmosphere and prepare users for the low light of the cinema, but if  it wasnt dimmed, users may find the transition between a brightly lit lobby and a dark cinema room more tricky, as I would take there eyes longer to adjust.


It is the quality of the information rather than the quantity that will be useful to me, so the questions I ask will have to be open, allowing for a variety of answers and prevent people from answering with yes/no.

Here are the questions I created.

Q.1 What are the factors that influence you the most when you first walk into a room/space ?
 Q.1b Can you list them in order of importance?

Q.2 What would you personally use to create a specific atmosphere in a space?
Q.2b Which of these elements would you consider the most important?

Q.3 Do you feel that spaces should be lit differently for different purposes?
       If yes, why?

Q.4 Have you ever been in a space where you found the lighting uncomfortable?

Q.5 Apart from reading any reviews or reccomendations, what would influence you to choose one Restauraunt over another?

When carrying out the interviews I used a semi-structured approach, using the questions I had prepeared, but also elaborating  on them in order to gain more information from the person being interviewed.


Here is a condensed version of a couple interview results.

Person 1
Name:    SuzieWilliams

Big windows, Colours, Light, Ventilation
 Q.1b Light/Big windows,Ventilation, Colours

Q.2b Lighting, Music, Plants

Q,3 Answer
Yes, Important to set the mood of the room

Yes, many times at librarys, supermarkets and some restaurants where "it was hard to see the food."

Q.5 Answer
Noise, external appearance, internal lighting scheme.

Person 2
Name:    Steve Evans
Age:       38
Gender:  Male

Q1. Answer
Overall atmosphere created by lighting and music, Layout, Decor
 Q.1b Overall atmosphere, Layout, Decor

Q.2 Answer
Warmth, decor/objects, lighting
Q.2b Lighting, Warmth, decor/objects


Q,3 Answer
Yes, "Because I like to create different feelings in a room to work in or to chill out."

Q4, Answer
Yes, Restraunts that are too bright "hate strip lighting in supermarkets, makes me leave quicker"

Q.5 Answer
Real fireplace inside restraunt, relaxed lighting and atmosphere

 From looking at my interview results, the way a space is lit seems to have a large impact on how people feel about it. The strip lighting in supermarkets and other public spaces can put people off, and force them to leave yet a soft mood light seen from outside a restaurant can draw people in. Light also is a tool people seem to  use readily when they are looking to create a specific atmosphere in a room.
