Quando la deumanizzazione ferisce: Attribuzioni di umanità e violenza

Stroop Task: È un compito in cui viene chiesto alle persone di indicare il colore di stimoli verbali presentati sullo schermo di un computer. In questa ricerca, gli stimoli sono nomi di quattro colori (rosso, blu, giallo e verde) o una stringa di “X”. Le prove compatibili sono quelle in cui il colore e coerente con il contenuto semantico della parola (ad es., ROSSO scritto in rosso); le prove incompatibili sono quelle in cui vi è incoerenza fra colore e contenuto semantico (ad es., ROSSO scritto in blu); le stringhe di “X” rappresentano le prove neutre. L’interferenza Stroop è calcolata come la differenza fra i tempi di risposta nelle prove incompatibili e i tempi di risposta nelle prove compatibili. Maggiore è il punteggio minore è l’efficienza delle funzioni esecutive.
