  Title Domestic dogs (Canis familiaris) are sensitive to the attentional state of humans Type Journal Article
  Year 2003 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol  
  Volume 117 Issue 3 Pages 257-263  
  Keywords Animals; *Appetitive Behavior; *Attention; *Bonding, Human-Pet; *Concept Formation; Cues; Dogs/*psychology; Female; Humans; *Inhibition (Psychology); Male; Nonverbal Communication  
  Abstract Twelve domestic dogs (Canis familiaris) were given a series of trials in which they were forbidden to take a piece of visible food. In some trials, the human continued to look at the dog throughout the trial (control condition), whereas in others, the human (a) left the room, (b) turned her back, (c) engaged in a distracting activity, or (d) closed her eyes. Dogs behaved in clearly different ways in most of the conditions in which the human did not watch them compared with the control condition, in which she did. In particular, when the human looked at them, dogs retrieved less food, approached it in a more indirect way, and sat (as opposed to laid down) more often than in the other conditions. Results are discussed in terms of domestic dogs' social-cognitive skills and their unique evolutionary and ontogenetic histories.

  Title Do humans ape? Or do apes human? Imitation and intention in humans (Homo sapiens) and other animals Type Journal Article
  Year 2003 Publication Journal of comparative psychology Abbreviated Journal J Comp Psychol  
  Volume 117 Issue 3 Pages 325-336  
  Keywords Adolescent; Adult; Animals; *Appetitive Behavior; Attention; Child, Preschool; Concept Formation; Female; Humans; *Imitative Behavior; Male; Motivation; Pan troglodytes/*psychology; *Problem Solving; *Psychomotor Performance; Reaction Time; Species Specificity  
  Abstract A. Whiten, D. M. Custance, J.-C. Gomez, P. Teixidor, and K. A. Bard (1996) tested chimpanzees' (Pan troglodytes) and human children's (Homo sapiens) skills at imitation with a 2-action test on an “artificial fruit.” Chimpanzees imitated to a restricted degree; children were more thoroughly imitative. Such results prompted some to assert that the difference in imitation indicates a difference in the subjects' understanding of the intentions of the demonstrator (M. Tomasello, 1996). In this experiment, 37 adult human subjects were tested with the artificial fruit. Far from being perfect imitators, the adults were less imitative than the children. These results cast doubt on the inference from imitative performance to an ability to understand others' intentions. The results also demonstrate how any test of imitation requires a control group and attention to the level of behavioral analysis.

  Title A gray seal's (Halichoerus grypus) responses to experimenter-given pointing and directional cues Type Journal Article
  Year 2003 Publication Journal of Comparative Psychology Abbreviated Journal J Comp Psychol  
  Volume 117 Issue 4 Pages 355-362  
  Keywords Animals; Behavior, Animal/*physiology; Cognition/physiology; Conditioning, Operant/physiology; *Cues; Eye Movements/physiology; Female; Seals, Earless  
  Abstract A gray seal (Halichoerus grypus) was trained to touch a target on its left or right by responding to pointing signals. The authors then tested whether the seal would be able to generalize spontaneously to altered signals. It responded correctly to center pointing and head turning, center upper body turning, and off-center pointing but not to head turning and eye movements alone. The seal also responded correctly to brief ipsilateral and contralateral points from center and lateral positions. Pointing gestures did not cause the seal to select an object placed centrally behind it. Like many animals in similar studies, this gray seal probably did not understand the referential character of these gestures but rather used signal generalization and experience from initial operant conditioning to solve these tasks.
