Animal ability to process and respond to stimuli is correlated with brain size. Small-brain animals tend to show simple behaviors that are less dependent on learning than those of large-brained animals. Vertebrates, particularly mammals, have larger brains and complex behavior that changes with experience.
The biosemiotic turn in Jakob von Uexküll's analysis occurs in his discussion of the animal's relationship with its environment. The umwelt is for him an environment-world which is, according to Agamben , "constituted by a more or less broad series of elements [called] 'carriers of significance' or 'marks' which are the only things that ...
For example, when timing a 10 sec interval an animal might be precise to within 1 sec, whereas when timing a 100 sec interval the animal would be precise to only about 10 sec. Thus time perception is like the perception of lights, sounds, and other sensory events, where precision is also relative to the size (brightness, loudness, etc.) of the ...
Tinbergen's four questions, named after 20th century biologist Nikolaas Tinbergen, are complementary categories of explanations for animal behaviour. These are also commonly referred to as levels of analysis. [1] It suggests that an integrative understanding of behaviour must include ultimate (evolutionary) explanations, in particular:
Prior to movement, an animal's current sensory state is used to generate a motor command. To generate a motor command, first, the current sensory state is compared to the desired or target state. Then, the nervous system transforms the sensory coordinates into the motor system's coordinates, and the motor system generates the necessary commands ...
The tagging technology used in the study could help us understand why some animals travel thousands of miles each year, like those who migrate between Europe and Africa, as well as work out how ...
Biological motion perception is the act of perceiving the fluid unique motion of a biological agent. The phenomenon was first documented by Swedish perceptual psychologist, Gunnar Johansson, in 1973. [1] There are many brain areas involved in this process, some similar to those used to perceive faces.
AMSTERDAM (Reuters) -The head of the chemical weapons watchdog said on Thursday he would ask Syria's new leaders to grant investigators access to the country to continue work identifying ...
