Stimulus Equivalencies Through Discrimination Reversals
The sensory systems of advanced animals frequently input more stimulus infonna-tion into the nervous system than the motor system can possibly output as behavior patterns. This bottleneck demands a drastic infonnation reduction. Two types of reduction can be distinguished: selective attention involving behavioral context-dependent infonnation censoring (as when during sexual behavior food stimu...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Discrimination of simultaneous and successive tones
A series of discrimination tasks involving simultaneous and successive presentation of pairs of piano notes was given to 27 Ss. The listeners exhibited less-than-perfect ability to "hear out" the component notes in simultaneous presentations. This finding, in agreement with the results of previous investigators, demonstrated the limitation of Ohm's law of acoustical analysis. It was also found ...
متن کاملLack of generalization of object discrimination between spatial contexts by a bat.
Discrimination and generalization are important elements of cognition in the daily lives of animals. Nectar-feeding bats detect flowers by olfaction and probably vision, but also use echolocation and echo-perception of flowers in immediate target surroundings. The echo received from an interference-rich flower corolla is a function of a bat's own relative position in space. This raises the ques...
متن کاملThe Effect of Ketanserin and Pirenperone Injected into the CA1 Region on Spatial Discrimination
In the present study, the effect of 5-HT2A receptor blockers in CA1 region of rat hippocampus on spatial learning was assessed in a T-maze, a spatial discrimination task. Rats were canulated bilaterally and injected daily vehicle (saline), 5-HT2A-selective antagonist, ketanserin (0.6, 1.2 or 2.4 µg/0.5 µl) and pirenperone (0.1, 0.3, 1.2 or 2.4 µg/0.5 µl) into the cannula 30 minutes before train...
