Orthographic processing in pigeons (Columba livia).
Learning to read involves the acquisition of letter-sound relationships (i.e., decoding skills) and the ability to visually recognize words (i.e., orthographic knowledge). Although decoding skills are clearly human-unique, given they are seated in language, recent research and theory suggest that orthographic processing may derive from the exaptation or recycling of visual circuits that evolved...
متن کاملImitation of conditional discriminations in pigeons (Columba livia).
In the present experiments, the 2-action method was used to determine whether pigeons could learn to imitate a conditional discrimination. Demonstrator pigeons (Columba livia) stepped on a treadle in the presence of 1 light and pecked at the treadle in the presence of another light. Demonstration did not seem to affect acquisition of the conditional discrimination (Experiment 1) but did facilit...
متن کاملFirst report of the Hadjelia truncata infestation in pigeons of Iran
Three adult pigeons (Columbia livia) belonging to a pigeon farm in Mashhad area were submitted toPoultry Clinic of School of Veterinary Medicine for post-mortem inspection. The farm had 150 adult pigeonsand a number of them suffered from a chronic disease with body weight loss, diarrhoea and weakness. Atnecropsy, slight to extreme enlargement with distortion were observed in gizzards of all car...
متن کاملTemporal modulation of spatial contrast vision in pigeons (Columba livia)
Spatiotemporal contrast sensitivity (CS) functions were obtained from four White Carneaux pigeons. The spatial frequency for each session was selected randomly from a group of five spatial frequencies ranging from 0.42 to 1.26 c/deg. Within the session, the temporal frequency varied from 1 to 32 Hz. When plotted as a function of spatial frequency, the CS functions peaked in the range 0.7-1.0 c/...
متن کاملThermal control of metabolic cold defence in pigeons columba livia
Metabolic rate (MR) and various body temperatures were recorded in pigeons Columba livia during gradual lowering of the ambient temperature (Ta) and during cold exposure (-10 degrees C) for an entire circadian cycle. The aim was to study how changes in MR accorded with the observed body temperature displacements and our knowledge of regional cold sensitivity. When Ta was lowered from 28 to -10 ...
