Top-down processing is defined as the development of pattern recognition through the use of contextual information.
At the time, the chief steward hadnât yet learned of the Titanicâs fate, so he wasnât even on the lookout for icebergs. He simply spotted a streak of red paint along the icebergâs base, which most likely meant a ship had collided with it in the last 12 hours.
1: Icebergs turn blue because of pressure that compacts the ice and dislodges the air trapped inside. Wrong, in fact the hollow areas with the most air (crevices and holes) are the bluest. 2. Old Icebergs are blue, young ones are not. Wrong. Often times ancient Icebergs are white and very young ones are deep blue. 3. Icebergs are blue because of refraction. Wrong. For those of you who do not remember what refraction is, think of what happens when you submerge part of a straight object like a pencil in water. The object appears to bend at the surface. There is some refraction in glaciers, but its effect is negligible.
