Experiments with Marta

Notes during the experiment:

– Marta sugiere mirar primer punto después de cada descanso.
– Marta dice que es más rápida con el índice (que indica izqda.) que con el corazón (que indica dcha.). Por eso hacemos un control con sólo 100 trials cambiando 20%-80% por 80%-20%.

Analysis:

>> load(‘c:\hipertec\decisionmaking\Resultados\marta1.mat’)
>> [correctos,procesados]=salida2procesados(Marta_con_fb);

>> corr_filt=correctos2correctos_filtrado(correctos,.05,[0 Inf]);

Reaction times histograms:

>> [histog,bins]=hist_norm(corr_filt.t_reaccion(corr_filt.dcha,1),15);
>> plot(bins,histog)
>> hold on
>> [histog,bins]=hist_norm(corr_filt.t_reaccion(~corr_filt.dcha,1),20);
>> plot(bins,histog,’r’)
>> legend(‘Right’,’Left’)
>> xlabel(‘Reaction time’)
>> xlabel(‘Reaction time (s)’)

Carpenter plots:

Learning:

aprendizaje=correctos2aprendizaje(corr_filt,100,1);

 

CONTROL, WITH INVERSE PROBABILITIES:

>> load(‘c:\hipertec\decisionmaking\Resultados\Marta2.mat’)
>> [correctos,procesados]=salida2procesados(Marta_con_fb_inv);

>> corr_filt=correctos2correctos_filtrado(correctos,.05,[0 .8]);
>> clf
>> [histog,bins]=hist_norm(corr_filt.t_reaccion(corr_filt.dcha,1),10);
plot(bins,histog)
hold on
[histog,bins]=hist_norm(corr_filt.t_reaccion(~corr_filt.dcha,1),5);
plot(bins,histog,’r’)
legend(‘Right’,’Left’)
xlabel(‘Reaction time’)
xlabel(‘Reaction time (s)’)

Learning:

>> aprendizaje=correctos2aprendizaje(corr_filt,10,1);

Probably the second experiment was too short for Marta to learn the prior.
