CSX milepost prefixes in Waycross, Georgia, 587 miles south of Richmond on the branch to Montgomery, Alabama (which splits near milepost 548 in Jesup). Three-letter prefixes are used for minor branches of these branches, or minor branches off the mainline - for instance ANA is the northernmost branch of AN. Before the ACL merged into the Seaboard Coast Line Railroad in 1967, none of the prefixes had the initial "A". The letters "I" and "Q" were skipped, and double-lettered prefixes (like KK, which would be AKK post-1967) were not used. A is given to the main line from Richmond, Virginia to Port of
Transposed letter effect the two middle letters with different letters (double substitute non-words). Baboons classified TL non-words as words significantly more often than double substitute non-words. There are a number of theories that have been challenged by the effects shown with transposition-letter priming. These theories mainly have to do with how letters are used to process words. Slot-based coding theory states that each letter in a word is connected to a particular location, or slot, within that word. One of the major theories that predict letter slots is the interactive activation model created by McClelland and Rumelhart (1981). This model assumes that people
