Unlock your super senses
In this video, there is volunteers to listen to certain sounds and their reaction to the sound. The first noises they had the volunteers listen to was good vibrations, but the people who were performing this experiment was controlling the sounds from behind. After everyone heard good vibrations, they started to hear bad vibrations. The bad vibrations were nails on a chalkboard, a ballon, dentist drills, and vomiting. The volunteers reactions to these sounds were their brain telling them but these sounds were bad vibrations compared to the good vibrations. The sense modality plays a role in this video because of the sounds because the volunteers heard the different sounds and reacted to them because their brain knew if it was a good vibration or bad vibration.
Reber Shukri Professor Vaughn Negative afterimage is a stimulus which elicits a positive image. In order to experience this, one can look at a bright source of light and then look away to a dark area. The way negative afterimage works is when the eye's photo-receptors which are the rods and cones adapt to over stimulation and lose sensitivity. The photo-receptors which are constantly exposed to the same stimulus will fatigue their supply of photo pigment, resulting a decrease in signal to the brain. The way negative afterimage connects to perception is because of bottom up processing where the stimulus influences what we perceive. https://www.youtube.com/watch?v=szy8iNCljlQ <Link to the video
