Selective Attention and Search Images in Pigeons by Blough, Patricia M

“…In a visual search task, pigeons detected targets when pretrial visual cues or blocked trial sequences signaled the target's identity. Sequential priming was…”

Visual effects of opiates in pigeons. I: Target location in visual search by BLOUGH, P. M, BLOUGH, D. S

“…Pigeons pecked at target forms, located in arrays of distractors. In experiment 1 the number of distractors and their similarity to the target varied. In…”

THE VISUAL ACUITY OF THE PIGEON FOR DISTANT TARGETS by Blough, Patricia M.

“…The acuity of six pigeons was measured in an apparatus that required the birds to make visual discriminations at a distance of 28.75 in. (73 cm) from the…”

The pigeon's distant visual acuity as a function of viewing angle by Uhlrich, D J, Blough, P M, Blough, D S

“…Distant visual acuity was determined for several viewing angles in two restrained White Carneaux pigeons. The behavioral technique was a classical conditioning…”
