Document Summary
Shadowing- participants hear a tape recording of someone speaking and must echo this speech back word for word while they are listening to it. Attended channel- presented through one earphone while. Unattended channel- is presented in the left earphone and participants are told to ignore this message. Dichotic listening is what this setup is referred to as. Most people perform well to this experiment. A filter protects us from potential distractors and allows us to focus. Participants unaware of fins but were still influenced by them. Change blindness- observers inability to detect changes in scenes they are looking directly at. Movies demonstrate this, happens with live events too. People don"t notice deliberate changes infront of them. Neurons are more responsive to attended inputs than to unattended ones. Rts were faster in the primed condition than neutral. Rts in the misled condition were the same as the neutral condition. High-validity primes showed faster reponses than low-validity primes.
