Books on vision science generally fall into two widely separated categories. There exists a mountain of near-plagiaristic basic undergraduate texts such as Sekuler and Blake, Goldstein, or Coren, Ward and Ennis that all contain pretty much the same basic stuff (Face-Vase illusions, Gibson vs Marr, etc) but aren't so hot when it comes to the practical aspects of conducting vision research. There are also high-level, jargon-filled techy tracts such as Wandell or Robson and Carpenter and other books that concentrate soley on classical psychophysical theory at the expense of practical laboratory methods such as Gescheider. In between, for a student who desires to go beyond the undergraduate level there is a sad absence of any decent books. This is primarily the fault of academic publishers who refuse to believe that there is a market for books at an intermediate level that bridge the gap between being an undergrad and being a postgrad. Bruce, Green and Georgeson fills this gap nicely. The previous two editions by just Bruce and Green concentrated more on visual cognition at the expense of psychophysics but the addition of Mark Georgeson as a third author has solved that problem. This really is an excellent textbook.
