Color recognition

Iam color blind .- Hmmm not completely ! .... Well atleast I dont have the sense of color ! ( Wait ... let me not be so harsh on myself ... I dont have the dressnig sense .... hmmm or a little milder would be My sense of fashion is weird .. !
Well maybe its because I cannot recognize different shades of color ? Here is a little experimental thought ....

  • You are shown one particular shade of brown .... for maybe 5 seconds .. ( CONTROL sample )
  • And then .... you are shown a palette of different shades of brown ( POPULATION sample )..... and asked to choose from it , the shade just saw ....
  • Can you pick the right shade ?? How much of a deviation would you cause ?
After thought : I found this task difficult with both CONTROL and POPULATION , both shown to the subject ! Now I can imagine how difficult it would be if the control sample is not shown ! Phew !

Future actions :
  • Build a small software and test it on different gender and age group .
  • Show the gradient ! Ask them to choose from it.
  • Now lets make the steps a little more difficult ... We donot give it as a gradient .. but a random scatter of shades ! ( whoa ! I know thats difficult )

I had this idea with the octaves - ( hmm ... the sounds .... do , re, me ...ring a bell ? ) . More on that later.

Checking your response time .


Small Decisions.
Thats the word for the day. ( okay .. 2-words) How can you ability to quickly adapt and respond to small decisions affect your life ?

That sounds a little deep. Here is the simpler version ! Very similar to checking your response time on some of those flash games . But this time,


To implement :
  • A software that takes in inputs from the user .
  • To start with, the screen flashes either of the 4 direction keys in random. ( step 2 )
  • The user responds by pressing the key displayed on the screen. ( step 3 )
  • The software calculates the time difference between step 2 and step 3.

How long does it need for one to recognize a face ?


If I were to flash a picture of a celebrity for 100 milliseconds , can you recognize that face ? Now how about 20 milliseconds ? Well .. it could vary between images - Is that what you think ?

To do :

Okay .. recognition of a face is little complex . Lets get to the micro level - Numbers.
If I were to see the number plate ( a 6 digit alpha-numeric pattern ) of a vehicle for a split second, can I remember that for a while ? ( atleast store it in my short term memory ? )

Implications :
Does this in anyway help decrease the myth of photographic memory ? Oh wait .. Iam talking split second photographic memory . ( If ever that exists ... )

Effect of time, mood swing and sleeplessness on biological clock

When I started off this experiment on myself, I was almost sure ( from the readings that I had done over the years) that there is a definite effect on our estimation of time based on the temperature of the body. ( I cannot recall the source though ) .

In other words, it meant something like " when you have a fever, your body clock runs faster .. so you think that 50 seconds might be actually 1 minute" or in other words.... time runs slower.

Factor 1 : Time of the day: Now I wanted to estimate this quantitatively, based on different factors . I estimated that probably time runs faster in the mornings ( when you are getting ready for office ) ... and runs little slower when you are bored . ( yeah .. dont we all know it )

Factor 2 : State of mind :
What is our perception of time with respect to our mood swings ?

Methodology
I developed a software ( screenshots attached ) which does the verification of the same .

To do :
Since this, like most of my other experiments , was done solely on myself, I wanted to extend it to the other spectrum of the society.
  • People with blindness.
  • Women in their different phases of ovulation cycles
  • People affected by cerebral Palsy (CP )
