  Title (up) Global-feature classification can be acquired more rapidly than local-feature classification in both humans and pigeons Type Journal Article
  Year 2004 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume 7 Issue 2 Pages 109-113  
  Keywords Adult; Animals; Behavior, Animal/physiology; *Classification; Columbidae/*physiology; *Discrimination Learning; Form Perception; Humans; *Mental Processes; *Pattern Recognition, Visual; Species Specificity  
  Abstract When humans process visual stimuli, global information often takes precedence over local information. In contrast, some recent studies have pointed to a local precedence effect in both pigeons and nonhuman primates. In the experiment reported here, we compared the speed of acquisition of two different categorizations of the same four geometric figures. One categorization was on the basis of a local feature, the other on the basis of a readily apparent global feature. For both humans and pigeons, the global-feature categorization was acquired more rapidly. This result reinforces the conclusion that local information does not always take precedence over global information in nonhuman animals.

  Title (up) Hippocampal lesions impair memory for location but not color in passerine birds Type Journal Article
  Year 1996 Publication Behavioral neuroscience Abbreviated Journal Behav Neurosci  
  Volume 110 Issue 4 Pages 831-835  
  Keywords Animals; Appetitive Behavior/physiology; Birds/*physiology; Brain Mapping; Color Perception/*physiology; Discrimination Learning/physiology; Hippocampus/*physiology; Long-Term Potentiation/physiology; Mental Recall/*physiology; Orientation/*physiology; Species Specificity  
  Abstract The effects of hippocampal complex lesions on memory for location and color were assessed in black-capped chickadees (Parus atricapillus) and dark-eyed juncos (Junco hyemalis) in operant tests of matching to sample. Before surgery, most birds were more accurate on tests of memory for location than on tests of memory for color. Damage to the hippocampal complex caused a decline in memory for location, whereas memory for color was not affected in the same birds. This dissociation indicates that the avian hippocampus plays an important role in spatial cognition and suggests that this brain structure may play no role in working memory generally.

  Title (up) Hippocampal volume and food-storing behavior are related in parids Type Journal Article
  Year 1995 Publication Brain, behavior and evolution Abbreviated Journal Brain Behav Evol  
  Volume 45 Issue 1 Pages 54-61  
  Keywords Animals; Appetitive Behavior/*physiology; Birds/*anatomy & histology; Brain Mapping; Evolution; Food Preferences/physiology; Hippocampus/*anatomy & histology; Mental Recall/*physiology; Orientation/*physiology; Predatory Behavior/physiology; Social Environment; Species Specificity  
  Abstract The size of the hippocampus has been previously shown to reflect species differences and sex differences in reliance on spatial memory to locate ecologically important resources, such as food and mates. Black-capped chickadees (Parus atricapillus) cached more food than did either Mexican chickadees (P. sclateri) or bridled titmice (P. wollweberi) in two tests of food storing, one conducted in an aviary and another in smaller home cages. Black-capped chickadees were also found to have a larger hippocampus, relative to the size of the telencephalon, than the other two species. Differences in the frequency of food storing behavior among the three species have probably produced differences in the use of hippocampus-dependent memory and spatial information processing to recover stored food, resulting in graded selection for size of the hippocampus.

  Title (up) Hippocampus and memory in a food-storing and in a nonstoring bird species Type Journal Article
  Year 1996 Publication Behavioral neuroscience Abbreviated Journal Behav Neurosci  
  Volume 110 Issue 5 Pages 946-964  
  Keywords Animals; Appetitive Behavior/*physiology; Attention/physiology; Birds/*physiology; Brain Mapping; Feeding Behavior/*physiology; Mental Recall/*physiology; Organ Size/physiology; Orientation/*physiology; Retention (Psychology)/physiology; Species Specificity  
  Abstract Food-storing birds maintain in memory a large and constantly changing catalog of the locations of stored food. The hippocampus of food-storing black-capped chickadees (Parus atricapillus) is proportionally larger than that of nonstoring dark-eyed juncos (Junco hyemalis). Chickadees perform better than do juncos in an operant test of spatial non-matching-to-sample (SNMTS), and chickadees are more resistant to interference in this paradigm. Hippocampal lesions attenuate performance in SNMTS and increase interference. In tests of continuous spatial alternation (CSA), juncos perform better than chickadees. CSA performance also declines following hippocampal lesions. By itself, sensitivity of a given task to hippocampal damage does not predict the direction of memory differences between storing and nonstoring species.

  Title (up) Host preference of mosquito vectors of Japanese encephalitis Type Journal Article
  Year 1975 Publication Zhonghua Minguo wei Sheng wu xue za zhi = Chinese Journal of Microbiology Abbreviated Journal Zhonghua Min Guo Wei Sheng Wu Xue Za Zhi  
  Volume 8 Issue 4 Pages 274-279  
  Keywords Animals; *Behavior, Animal; Birds/blood; *Culex; Ecology; Encephalitis, Japanese/*transmission; *Feeding Behavior; Female; Humans; *Insect Vectors; Mammals/blood; Species Specificity; Taiwan  
  Abstract The host preference of 4 Culex mosquito species collected in Miaoli and Pingtung counties, Taiwan was studied by capillary precipitin method. Antisera to alum-precipitated sera of man, bovine, swine, rabbit, horse, dog, cat, mouse, chicken, duck, and pigeon were produced in rabbits and reacted with 758 mosquito blood meals among which reactions to one or more antisera. Culex annulus and Culex tritaeniorhynchus summorosus showed a great avidity for pig, and Culex fuscocephala for bovine. Culex pipiens fatigans was ornithophilic. None of 110 C. t. summorosus and 2.4% of 223 C. annulus had fed on man. Among 66 samples of C.p. fatigans tested 10.3% had fed on man, while none of 359 C. fuscocephala did. It seems that the latter does not act as a primary vector of Japanese encephalitis.

  Title (up) How great apes perform on a modified trap-tube task Type Journal Article
  Year 2006 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume 9 Issue 3 Pages 193-199  
  Keywords Animals; *Discrimination Learning; Female; Gorilla gorilla; Hominidae/*psychology; *Intelligence; Male; *Motor Skills; Pan paniscus; Pan troglodytes; Pongo pygmaeus; *Problem Solving; Species Specificity  
  Abstract To date, neither primates nor birds have shown clear evidence of causal knowledge when attempting to solve the trap tube task. One factor that may have contributed to mask the knowledge that subjects may have about the task is that subjects were only allowed to push the reward away from them, which is a particularly difficult action for primates in certain problem solving situations. We presented five orangutans (Pongo pygmaeus), two chimpanzees (Pan troglodytes), two bonobos (Pan paniscus), and one gorilla (Gorilla gorilla) with a modified trap tube that allowed subjects to push or rake the reward with the tool. In two additional follow-up tests, we inverted the tube 180 degrees rendering the trap nonfunctional and also presented subjects with the original task in which they were required to push the reward out of the tube. Results showed that all but one of the subjects preferred to rake the reward. Two orangutans and one chimpanzee (all of whom preferred to rake the reward), consistently avoided the trap only when it was functional but failed the original task. These findings suggest that some great apes may have some causal knowledge about the trap-tube task. Their success, however, depended on whether they were allowed to choose certain tool-using actions.

  Title (up) Inferences by exclusion in the great apes: the effect of age and species Type Journal Article
  Year 2006 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume 9 Issue 4 Pages 393-403  
  Keywords Age Factors; Animals; Association Learning; *Cognition; *Concept Formation; *Discrimination Learning; Female; Gorilla gorilla; Hominidae/classification/*psychology; Male; Pan paniscus; Pan troglodytes; Pongo pygmaeus; *Problem Solving; Species Specificity  
  Abstract This study investigated the ability of chimpanzees, gorillas, orangutans, and bonobos to make inferences by exclusion using the procedure pioneered by Premack and Premack (Cognition 50:347-362, 1994) with chimpanzees. Thirty apes were presented with two different food items (banana vs. grape) on a platform and covered with identical containers. One of the items was removed from the container and placed between the two containers so that subjects could see it. After discarding this item, subjects could select between the two containers. In Experiment 1, apes preferentially selected the container that held the item that the experimenter had not discarded, especially if subjects saw the experimenter remove the item from the container (but without seeing the container empty). Experiment 3 in which the food was removed from one of the containers behind a barrier confirmed these results. In contrast, subjects performed at chance levels when a stimulus (colored plastic chip: Exp. 1; food item: Exp. 2 and Exp. 3) designated the item that had been removed. These results indicated that apes made inferences, not just learned to use a discriminative cue to avoid the empty container. Apes perceived and treated the item discarded by the experimenter as if it were the very one that had been hidden under the container. Results suggested a positive relationship between age and inferential ability independent of memory ability but no species differences.

  Title (up) Influence of sound specificity and familiarity on Japanese macaques' (Macaca fuscata) auditory laterality Type Journal Article
  Year 2010 Publication Behavioural Brain Research Abbreviated Journal Behav. Brain. Res.  
  Volume 208 Issue 1 Pages 286-289  
  Keywords Auditory processing; Hemispheric specialisation; Specificity; Familiarity; Head-turn paradigm; Macaque  
  Abstract Despite attempts to generalise the left hemisphere-speech association of humans to animal communication, the debate remains open. More studies on primates are needed to explore the potential effects of sound specificity and familiarity. Familiar and non-familiar nonhuman primate contact calls, bird calls and non-biological sounds were broadcast to Japanese macaques. Macaques turned their heads preferentially towards the left (right hemisphere) when hearing conspecific or familiar primates supporting hemispheric specialisation. Our results support the role of experience in brain organisation and the importance of social factors to understand laterality evolution.

  Title (up) Influence of various early human-foal interferences on subsequent human-foal relationship Type Journal Article
  Year 2006 Publication Developmental psychobiology Abbreviated Journal Dev Psychobiol  
  Volume 48 Issue 8 Pages 712-718  
  Keywords Animal Husbandry/methods; Animals; Animals, Newborn/*psychology; Animals, Suckling/*psychology; Behavior, Animal; Female; *Handling (Psychology); Horses/*psychology; Humans; Mothers/psychology; *Object Attachment; Species Specificity  
  Abstract Whereas the way animals perceive human contact has been particularly examined in pet animals, a small amount of investigations has been done in domestic ungulates. It was nevertheless assumed that, as pet animals, non-aggressive forms of tactile contact were as well rewarding or positive for these species, even though the features of intraspecific relationships in pet animals and domestic ungulates may be to some extent different.We test here the hypothesis that horses may not consider physical handling by humans as a positive event. When comparing different early human-foal interactions, we found that early exposure to a motionless human enhanced slightly foals reactions to humans whereas forced stroking or handling in early life did not improve later human-foal relation. Foals that were assisted during their first suckling (e.g., brought to the dam's teat) even tended to avoid human approach at 2 weeks, and physical contact at 1 month of age.We argue that interspecies differences may exist in how tactile stimulation is perceived. It may be important for the establishment of a bond that a young animal is active in the process and able, through its behavioral responses, to help define what is positive for it. This way of investigation may have important general implications in how we consider the development of social relations, both within and between species.

  Title (up) Intrageneric amplification of horse microsatellite markers with emphasis on the Przewalski's horse (E. przewalskii) Type Journal Article
  Year 1994 Publication Animal Genetics Abbreviated Journal Anim Genet  
  Volume 25 Issue 6 Pages 401-405  
  Keywords Animals; DNA, Satellite/*genetics; *Gene Amplification; Gene Frequency; *Genetic Markers; Heterozygote; Horses/*genetics; Species Specificity  
  Abstract Primer sequences flanking 13 microsatellite loci isolated from the domestic horse (E. caballus) were successfully used to amplify homologous loci in the Przewalski's horse (E. przewalskii). The results demonstrate that the level of polymorphism at all 13 loci in the Przewalski's horse was comparable to that in the domestic horse and the overall exclusion probability in the Przewalski's horse was calculated to be 0.9994. The results suggest that it should be possible to use E. caballus-derived microsatellite markers to provide parentage verification and additional valuable information to the captive management of E. przewalskii. The ability to amplify corresponding loci in the remaining five species of the genus was also confirmed, illustrating the general application of markers isolated from the domestic horse to the evaluation of polymorphism in the other six species of the genus.
