Darwin's negro bird-stuffer
Charles Darwin wrote in his Autobiography (1, 2) that when he was a medical student at Edinburgh (1825 Oct.—1827 Apr.) ‘a negro lived in Edinburgh, who had travelled with Waterton, and gained his livelihood by stuffing birds, which he did excellently: he gave me lessons for payment, and I often used to sit with him, for he was a very pleasant and intelligent man’. Darwin does not name him and he is not mentioned in Darwinian literature except in …
Decrement of Visual Acuity Resulting From Two Types of Visual Detection Task
Parafoveal visual acuity (a modified Landolt ring) was reduced by a simultaneous foveal detection task. Two types of foveal tasks were used: Landolt ring and upper-case letter. The foveal letter target reduced acuity of the parafoveal ring by a greater amount than did the foveal Landolt ring
Dimensional and Judgmental Determinants of Illusions of Visual Size
The influence of modified forms of the Ponzo-illusion figure and densitygradient patterns on the apparent size of lines and circles was investigated. Consistent with previous reports, the predictions of constancy scaling theory were not confirmed. The results are shown to be dependent both on visual size-comparison mechanisms and judgmental variables
