  Title Complementary hemispheric specialization in monkeys Type Journal Article
  Year 1988 Publication Science Abbreviated Journal Science  
  Volume 242 Issue 4886 Pages (down) 1691-1694  
  Keywords  
  Abstract Twenty-five split-brain monkeys were taught to discriminate two types of visual stimuli that engage lateralized cerebral processing in human subjects. Differential lateralization for the two kinds of discriminations was found; the left hemisphere was better at distinguishing between tilted lines and the right hemisphere was better at discriminating faces. These results indicate that lateralization of cognitive processing appeared in primates independently of language or handedness. In addition, cerebral lateralization in monkeys may provide an appropriate model for studying the biological basis of hemispheric specialization.

  Title Word Learning in a Domestic Dog: Evidence for “Fast Mapping” Type Journal Article
  Year 2004 Publication Science Abbreviated Journal Science  
  Volume 304 Issue 5677 Pages (down) 1682-1683  
  Keywords  
  Abstract During speech acquisition, children form quick and rough hypotheses about the meaning of a new word after only a single exposure--a process dubbed “fast mapping.” Here we provide evidence that a border collie, Rico, is able to fast map. Rico knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those items right away as well as 4 weeks after the initial exposure. Fast mapping thus appears to be mediated by general learning and memory mechanisms also found in other animals and not by a language acquisition device that is special to humans.

  Title The domestication of social cognition in dogs Type Journal Article
  Year 2002 Publication Science (New York, N.Y.) Abbreviated Journal Science  
  Volume 298 Issue 5598 Pages (down) 1634-1636  
  Keywords Animals; *Animals, Domestic; *Behavior, Animal; *Cognition; *Cues; *Dogs; Food; Humans; Memory; Pan troglodytes; *Social Behavior; Species Specificity; Vision; Wolves  
  Abstract Dogs are more skillful than great apes at a number of tasks in which they must read human communicative signals indicating the location of hidden food. In this study, we found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old, even those that have had little human contact, do show these skills. These findings suggest that during the process of domestication, dogs have been selected for a set of social-cognitive abilities that enable them to communicate with humans in unique ways.

  Title Wolves, Moose, and Tree Rings on Isle Royale Type Journal Article
  Year 1994 Publication Science Abbreviated Journal Science  
  Volume 266 Issue 5190 Pages (down) 1555-1558  
  Keywords  
  Abstract Investigation of tree growth in Isle Royale National Park in Michigan revealed the influence of herbivores and carnivores on plants in an intimately linked food chain. Plant growth rates were regulated by cycles in animal density and responded to annual changes in primary productivity only when released from herbivory by wolf predation. Isle Royale's dendrochronology complements a rich literature on food chain control in aquatic systems, which often supports a trophic cascade model. This study provides evidence of top-down control in a forested ecosystem.

  Title Superfamilies of Evolved and Designed Networks Type Journal Article
  Year 2004 Publication Science Abbreviated Journal Science  
  Volume 303 Issue 5663 Pages (down) 1538-1542  
  Keywords  
  Abstract Complex biological, technological, and sociological networks can be of very different sizes and connectivities, making it difficult to compare their structures. Here we present an approach to systematically study similarity in the local structure of networks, based on the significance profile (SP) of small subgraphs in the network compared to randomized networks. We find several superfamilies of previously unrelated networks with very similar SPs. One superfamily, including transcription networks of microorganisms, represents “rate-limited” information-processing networks strongly constrained by the response time of their components. A distinct superfamily includes protein signaling, developmental genetic networks, and neuronal wiring. Additional superfamilies include power grids, protein-structure networks and geometric networks, World Wide Web links and social networks, and word-adjacency networks from different languages.

  Title Cooperative Hunting Harris' Hawks (Parabuteo unicinctus) Type Journal Article
  Year 1988 Publication Science Abbreviated Journal Science  
  Volume 239 Issue 4847 Pages (down) 1525-1527  
  Keywords  
  Abstract Coordinated hunting by several individuals directed toward the capture and sharing of one Large prey animal has been documented convincingly only for a few mammalian carnivores. In New Mexico, Harris' hawks formed hunting parties of two to six individuals in the nonbreeding season. This behavior improved capture success and the average energy available per individual enabled hawks to dispatch prey larger than themselves. These patterns suggest that cooperation is important to understanding the evolution of complex social behavior in higher vertebrates and, specifically, that benefits derived from team hunting a key factor in the social living of Harris' hawks.

  Title Observation Learning in Cats Type Journal Article
  Year 1968 Publication Science Abbreviated Journal Science  
  Volume 159 Issue 3822 Pages (down) 1489-1491  
  Keywords  
  Abstract In two experiments cats acquired a stimulus-controlled approach or avoidance response by observational or conventional shaping procedures. Observer cats acquired the avoidance response (hurdle jumping in response to a buzzer stimulus) significantly faster and made fewer errors than cats that were conventionally trained. Observer cats acquired the approach response (lever pressing for food in response to a light stimulus) with significantly fewer errors than cats that were conventionally trained. In some cases, observer cats committed one or no errors while reaching criterion.

  Title Empathy and Pro-Social Behavior in Rats Type Journal Article
  Year 2011 Publication Science Abbreviated Journal Science  
  Volume 334 Issue 6061 Pages (down) 1427-1430  
  Keywords  
  Abstract Whereas human pro-social behavior is often driven by empathic concern for another, it is unclear whether nonprimate mammals experience a similar motivational state. To test for empathically motivated pro-social behavior in rodents, we placed a free rat in an arena with a cagemate trapped in a restrainer. After several sessions, the free rat learned to intentionally and quickly open the restrainer and free the cagemate. Rats did not open empty or object-containing restrainers. They freed cagemates even when social contact was prevented. When liberating a cagemate was pitted against chocolate contained within a second restrainer, rats opened both restrainers and typically shared the chocolate. Thus, rats behave pro-socially in response to a conspecific�s distress, providing strong evidence for biological roots of empathically motivated helping behavior.
