After rehearsing the response alternatives, we now can enter the research approach we need in the cognition field.

Its good to realize that this cognition approach is different from the emotion approach.

The basic concept is that two pictures follow each other in time.
Second important issue is that pictures presented first are never presented as second picture and that pictures presented as second picture never are presented as first picture. This sounds perhaps simple but it is an essential element in this approach.


Lets keep it simple and search for the use of a gender concept:
Is the perceiver using a gender concept in identifying the person on the second picture?


We work with three sets of pictures:

SetA: different pictures of women, as representative as possible
SetB: different pictures of men, as representative as possible
SetC: the response set: different men and women not present in SetA or SetB



Four combinations are possible:

a woman from  SetA  in time followed by a woman  from SetC
a woman from  SetA  in time followed by a man       from SetC
a man from       SetB  in time followed by a man       from SetC
a man from       SetB  in time followed by a woman  from SetC


The minimal number of identifyable pictures within the response set is four
two women and two men from SetC.

To make the research more reliable we take in our example three women and tree men from our SetC.

And to make it even more reliable we put in SetC three different pictures of the same person.

So in total we have 9 women and 9 men in our SetC, three of each identity.

Preceded by a man or a woman from SetB or SetA means that we have 36 pairs.


Now we have to choose for different presentationtime relations
the minimal number is two.

So we have to define TimeRelation1 and TimeRelation2

Fixating the total PresentationTime on 80 milliseconds as in the reported research.
We choose for:
TimeRelation1 is: 50:30 Milliseconds
TimeRelation2 is: 70:10 Milliseconds
as in the reported research

But you can yourself choose for other timerelations.

In one block of 36 men and women presented in two Timerelations we have 72 pairs of pictures to be presented.

This number of pairs seems a bit much to me, it can be done but perhaps another strategy to limit the number of pairs:
In one block we can limit the number of pairs by choosing only one identity from SetC.
In doing so we have 3 men and 3 women preceded by one man or woman that makes 12 pairs.
These twelve pairs combined with two timerelations makes 24 pairs in 1 block.
That seems a nice reduction to me.

And this leads us to the question: what is the minimum number of pairs in a block?

Multiple blocks can be presented: within every block the same TimeRelations, the same persons to identify from Setc and with a random selection of men and women form SetA and SetB.



And we will Google ask for help.
 

So lets see what SetA, SetB and SetC contain.
