  Title (up) Search behavior in cats and dogs Interspecific differences in working memory and spatial cognition Type Journal Article
  Year 1996 Publication Animal Learning & Behavior Abbreviated Journal Anim Learn. & Behav.  
  Volume 24 Issue 2 Pages 142-149  
  Keywords  
  Abstract Cats and dogs search behavior was compared in different problems where an object was visibly

moved behind a screen that was then visibly moved to a new position. In Experiments 1 (cats) and 2 (dogs),

one group was tested with identical screens and the other group was tested with dissimilar screens.

Results showed that in both species, search behavior was based on processing of spatial information

rather than on recognition of the visual features of the target screen. Cats and dogs were unable to find

the object by inferring its invisible movement. They reached a high level of success only if there was

direct perceptual evidence that the object could not be at its initial position. When the position change

was indicated by an indirect cue, cats searched more at the object`s initial than final position, whereas

dogs searched equally at both positions. Interspecific similarities and differences are interpreted in

terms of the requirements for resetting working memory.

  Title (up) Social manipulation causes cooperation in keas Type Journal Article
  Year 1996 Publication Abbreviated Journal  
  Volume 52 Issue 1 Pages 1-10  
  Keywords  
  Abstract Abstract. This study assessed whether keas,Nestor notabilis, are able to cooperate in an instrumental task. Seven birds of a captive group were tested in group situations and in dyads. At least two individuals had to manipulate an apparatus to obtain food but only one participant was rewarded. One bird had to push down a lever to enable another one to collect food from a box. The distribution of the two different roles was clearly dependent on hierarchy. The higher ranking individual always obtained the reward and each bird changed its role according to dominance status. Owing to the non-linear hierarchy in the group, each bird participating in cooperative interactions had at least one submissive partner. Therefore, in group situations the reward was distributed symmetrically and cooperation was persistent. In dyadic test situations, three individual keas aggressively manipulated their respective subordinate partners to open the apparatus. Their dominance status enabled them to force cooperation.

  Title (up) Species and sex differences in hippocampus size in parasitic and non-parasitic cowbirds Type Journal Article
  Year 1996 Publication Neuroreport Abbreviated Journal Neuroreport  
  Volume 7 Issue 2 Pages 505-508  
  Keywords Animals; Birds/*physiology; Female; Hippocampus/*anatomy & histology; Male; Nesting Behavior/*physiology; Sex Characteristics; Species Specificity; Telencephalon/anatomy & histology  
  Abstract To test the hypothesis that selection for spatial abilities which require birds to locate and to return accurately to host nests has produced an enlarged hippocampus in brood parasites, three species of cowbird were compared. In shiny cowbirds, females search for host nests without the assistance of the male; in screaming cowbirds, males and females inspect hosts' nests together; in bay-winged cowbirds, neither sex searches because this species is not a brood parasite. As predicted, the two parasitic species had a relatively larger hippocampus than the non-parasitic species. There were no sex differences in relative hippocampus size in screaming or bay-winged cowbirds, but female shiny cowbirds had a larger hippocampus than the male.
