1. 1. Cognition in black-handed spider monkeys (Ateles geoffroyi): A battery of behavioral tests

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Tiffany Claire Bosshard; [2020]
   Keywords : cognition; behavior; object permanence; associative learning; quantity discrimination; numerosity; long-term memory; spider monkey;

   Abstract : Cognition allows animals to acquire, process, and store sensory information from the environment and use it to adapt to their surroundings. A battery of behavioral tests was used to assess the cognitive abilities of black-handed spider monkeys (Ateles geoffroyi). READ MORE

3. 2. Training of spider monkeys in a food-rewarded two-choice olfactory discrimination paradigm and assessment of olfactory learning and memory performance

   University essay from Linköpings universitet/Biologi

   Author : Emmi Aineslahti; [2019]
   Keywords : Ateles geoffroyi; behavioral testing; discrimination learning; odor memory; olfaction; olfactory discrimination; olfactory learning; spider monkey;

   Abstract : There is little knowledge about olfactory learning in primates, even though primates are known to use olfaction in several behaviors including food selection and territorial defense. Therefore I assessed the olfactory learning and memory performance in five adult spider monkeys (Ateles geoffroyi) using a food-rewarded two-choice olfactory discrimination paradigm. READ MORE

4. 3. Olfactory sensitivity of human subjects for six predator odorants

   University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

   Author : Amir Sarrafchi; [2012]
   Keywords : Human olfactory sensitivity; predator odor; sulfur-containing odorant; sex difference;

   Abstract : The purpose of the present study was to determine olfactory detection thresholds in human subjects for a set of six sulfur-containing odorants which are known to be components of mammalian predator odors. Using a threealternative ascending staircase procedure, the olfactory sensitivity of 12 healthy adult human subjects, 6 males and 6 females was assessed with 2-propylthietane, 2,2-dimethylthietane, 3-mercapto-3-methylbutan-1-ol, 3-mercapto-3- methylbutyl formate, 3-methyl-1-butanethiol, and methyl-2-phenylethyl sulfide.

5. 4. Odor sensitivity in CD-1 mice for "green" odors

   University essay from Molekylär genetik

   Author : Sathish kumar Murali; [2011]
   Keywords : CD-1 mice; ―green‖ odors; Odor sensitivity and detection threshold values;

   Abstract : ―Green‖ odors comprise a group of eight structurally related aliphatic alkenals and alkenols which are characteristic for the odor of a wide variety of plant materials. Using an automated olfactometer, the olfactory detection thresholds for ―green‖ odors were determined in six CD-1 mice and compared with that of spider monkeys and human subjects. READ MORE

6. 5. Olfactory sensitivity of spider monkeys (Ateles geoffroyi) for "green odors"

   University essay from Institutionen för fysik, kemi och biologi

   Author : Pia Katrine Løtvedt; [2011]
   Keywords : Ateles geoffroyi; green odors ; olfaction; olfactory detection thresholds; spider monkeys;

   Abstract : Primates have traditionally been viewed as having a poorly developed sense of smell. However, in recent years, studies have shown that at least some primate species use olfaction in a number of behaviors, and that they have a high olfactory sensitivity for various chemical classes of odorants.
