| Popis: | 1. The present study describes the effects of novelty (experiment 1) and restraint (experiment 2) on the catecholamine responses in laying hens. 2. Manual restraint caused a higher catecholamine response than mere visual exposure to a human being wearing yellow gloves and swinging his hand in the bird's home cage. 3. A relationship could be shown between adrenaline concentrations in plasma after a novel stimulus and the duration of tonic immobility. |
