Synopsis
Excerpt from An Experimental Investigation of the Positive After-Image in Audition
We chose the lights as signals because they were silent; but they were not reliable; and we now substituted for them small electro magnets from a player-piano. These magnets are not noisy; and when Operated by a weak current, just strong enough to produce a light, quick movement, they did not annoy the O's. To the armature of the magnet we soldered a strip of tin, 4 cm. By cm., to serve as signal flag. Every 0 had a magnet and flag in his booth before him, at the place where the light had been. When the current was Off, the flag stood almost vertically; when it was turned on, the flag was pulled quickly down to the horizontal.

Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book delves into the realm of human perception through the intriguing lens of auditory experiences. The author explores the existence of a positive after-image in hearing, akin to the visual phenomenon witnessed in vision. Through meticulous experimentation involving sound stimulation and precise timing, the author sought to uncover the presence of such an after-image. The book meticulously outlines experimental setups, exploring the role of variables like sound intensity and duration on the perception of sound cessation. While the quest for a definitive auditory after-image proved elusive, the author unveils a fascinating array of modified endings and recurrent images experienced by participants. These findings enrich our understanding of how we perceive and interpret auditory stimuli. The book not only contributes to the scientific understanding of human sensation but also sheds light on the interplay between subjective and objective factors in our auditory experiences. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781333223618_0
