The Shaping Of A Saint-President: Latent Clues From Nelson Mandela's Autobiography, Abdulrazaq Imam

Abdulrazaq A. Imam

Nelson Mandela's Long Walk to Freedom provides evidence organized in the form of antecedent-behavior-consequence units, which suggest that a shaping process effected during his many years of incarceration best describes the origins of the outcome represented by the political order in South Africa following his release. The analysis shows that Mandela's radicalism at the start of his imprisonment on Robben Island changed into a saintly presidential aura in the end, through a systematic selection process that actively involved Mandela himself and his political aspirations. The saintly qualities ascribed to Mandela after his release by many around the world are consistent …

Integration Of Speed Signals In The Direction Of Motion, Dawn Vreven, Preeti Verghese

Dawn L Vreven

Speed discrimination tasks were used to examine the spatial and temporal characteristics of the integration mechanism involved when signals are extended in the direction of motion. We varied the aspect ratio of a signal patch whose speed differed from the background, while holding the area of the signal patch constant, so that the signal patch could be either extended in the direction of motion or extended orthogonal to the direction of motion. Speed discrimination thresholds decreased dramatically as the signal patch was extended in the direction of motion. The spatial and temporal integration regions were larger than would be expected …
