  Title One-encounter search-image formation by araneophagic spiders Type Journal Article
  Year 2004 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume 7 Issue 4 Pages 247-254  
  Keywords Animals; Appetitive Behavior; *Association Learning; *Attention; Choice Behavior; Field Dependence-Independence; *Food Preferences; *Pattern Recognition, Visual; *Predatory Behavior; Signal Detection (Psychology); *Spiders  
  Abstract An experimental study of search-image use by araneophagic jumping spiders (i.e., salticid spiders that prey routinely on other spiders) supports five conclusions. First, araneophagic salticids have an innate predisposition to form search images for specific prey from their preferred prey category (spiders) rather than for prey from a non-preferred category (insects). Second, single encounters are sufficient for forming search images. Third, search images are based on selective attention specifically to optical cues. Fourth, there are trade-offs in attention during search-image use (i.e., forming a search image for one type of spider diminishes the araneophagic salticid's attention to other spiders). Fifth, the araneophagic salticid's adoption of search images is costly to the prey (i.e., when the araneophagic salticid adopts a search, the prey's prospects for surviving encounters with the araneophagic salticid are diminished). Cognitive and ecological implications of search-image use are discussed.

  Title Body orientation and face orientation: two factors controlling apes' behavior from humans Type Journal Article
  Year 2004 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume 7 Issue 4 Pages 216-223  
  Keywords Animals; *Attention; *Behavior, Animal; Cognition; *Concept Formation; Face; Facial Expression; Female; Fixation, Ocular; Hominidae/*psychology; Humans; Male; *Nonverbal Communication; *Orientation; Pan paniscus/psychology; Pan troglodytes/psychology; Pongo pygmaeus/psychology; *Posture; Social Perception; Species Specificity  
  Abstract A number of animal species have evolved the cognitive ability to detect when they are being watched by other individuals. Precisely what kind of information they use to make this determination is unknown. There is particular controversy in the case of the great apes because different studies report conflicting results. In experiment 1, we presented chimpanzees, orangutans, and bonobos with a situation in which they had to request food from a human observer who was in one of various attentional states. She either stared at the ape, faced the ape with her eyes closed, sat with her back towards the ape, or left the room. In experiment 2, we systematically crossed the observer's body and face orientation so that the observer could have her body and/or face oriented either towards or away from the subject. Results indicated that apes produced more behaviors when they were being watched. They did this not only on the basis of whether they could see the experimenter as a whole, but they were sensitive to her body and face orientation separately. These results suggest that body and face orientation encode two different types of information. Whereas face orientation encodes the observer's perceptual access, body orientation encodes the observer's disposition to transfer food. In contrast to the results on body and face orientation, only two of the tested subjects responded to the state of the observer's eyes.

  Title Using self-view television to distinguish between self-examination and social behavior in the bottlenose dolphin (Tursiops truncatus) Type Journal Article
  Year 1995 Publication Consciousness and Cognition Abbreviated Journal Conscious Cogn  
  Volume 4 Issue 2 Pages 205-224  
  Keywords Animal Communication; Animals; *Attention; Discrimination Learning; Dolphins/*psychology; Female; Male; *Self Concept; *Social Behavior; *Television; *Visual Perception  
  Abstract In mirror mark tests dolphins twist, posture, and engage in open-mouth and head movements, often repetitive. Because postures and an open mouth are also dolphin social behaviors, we used self-view television as a manipulatable mirror to distinguish between self-examination and social behavior. Two dolphins were exposed to alternating real-time self-view (“mirror mode”) and playback of the same to determine if they distinguished between them. The adult male engaged in elaborate open-mouth behaviors in mirror mode, but usually just watched when played back the same material. Mirror mode behavior was also compared to interacting with real dolphins (controls). Mark tests were conducted, as well as switches from front to side self-views to see if the dolphins turned. They presented marked areas to the self-view television and turned. The results suggest self-examination over social behavior.

  Title Capuchin cognitive ecology: cooperation based on projected returns Type Journal Article

  Volume 41 Issue 2 Pages 221-228  
  Keywords Animals; Attention; Cebus/*psychology; *Cooperative Behavior; Decision Making; Dominance-Subordination; Female; Male; *Motivation; Reaction Time; Reinforcement Schedule; *Social Behavior  
  Abstract Stable cooperation requires that each party's pay-offs exceed those available through individual action. The present experimental study on brown capuchin monkeys (Cebus apella) investigated if decisions about cooperation are (a) guided by the amount of competition expected to follow the cooperation, and (b) made instantaneously or only after a period of familiarization. Pairs of adult monkeys were presented with a mutualistic cooperative task with variable opportunities for resource monopolization (clumped versus dispersed rewards), and partner relationships (kin versus nonkin). After pre-training, each pair of monkeys (N=11) was subjected to six tests, consisting of 15 2 min trials each, with rewards available to both parties. Clumped reward distribution had an immediate negative effect on cooperation: this effect was visible right from the start, and remained visible even if clumped trials alternated with dispersed trials. The drop in cooperation was far more dramatic for nonkin than kin, which was explained by the tendency of dominant nonkin to claim more than half of the rewards under the clumped condition. The immediacy of responses suggests a decision-making process based on predicted outcome of cooperation. Decisions about cooperation thus take into account both the opportunity for and the likelihood of subsequent competition over the spoils.

  Title A cognitive behaviorist approach to the study of animal behavior Type Journal Article
  Year 2002 Publication The Journal of general psychology Abbreviated Journal J Gen Psychol  
  Volume 129 Issue 4 Pages 328-363  
  Keywords Animals; *Attention; *Behavior, Animal; *Cognition; Learning; *Memory; Social Behavior  
  Abstract Traditional psychological approaches to animal learning and behavior have involved either the atheoretical behaviorist approach proposed by B. F. Skinner (1938), in which input-output relations are described in response to environmental manipulations, or the theoretical behaviorist approach offered by C. L Hull (1943), in which associations mediated by several hypothetical constructs and intervening variables are formed between stimuli and responses. Recently, the application of a cognitive behaviorist approach to animal learning and behavior has been found to have considerable value as a research tool. This perspective has grown out of E. C. Tolman's cognitive approach to learning in which behavior is mediated by mechanisms that are not directly observable but can be inferred from the results of critical experiments. In the present article, the author presents several examples of the successful application of the cognitive behaviorist approach. In each case, the experiments have been designed to distinguish between more traditional mechanisms and those mediated by hypothesized internal representations. These examples were selected because the evidence suggests that some form of active cognitive organization is needed to account for the behavioral results.

  Title Timing in pigeons: effects of the similarity between intertrial interval and gap in a timing signal Type Journal Article
  Year 2002 Publication Journal of experimental psychology. Animal behavior processes Abbreviated Journal J Exp Psychol Anim Behav Process  
  Volume 28 Issue 4 Pages 416-422  
  Keywords Animals; *Attention; Columbidae; *Conditioning, Operant; Discrimination Learning; Mental Recall; Probability Learning; *Reinforcement (Psychology); *Reinforcement Schedule; Retention (Psychology); Time Factors; *Time Perception/physiology  
  Abstract Previous research suggests that when a fixed interval is interrupted (known as the gap procedure), pigeons tend to reset memory and start timing from 0 after the gap. However, because the ambient conditions of the gap typically have been the same as during the intertrial interval (ITI), ambiguity may have resulted. In the present experiment, the authors found that when ambient conditions during the gap were similar to the ITI, pigeons tended to reset memory, but when ambient conditions during the gap were different from the ITI, pigeons tended to stop timing, retain the duration of the stimulus in memory, and add to that time when the stimulus reappeared. Thus, when the gap was unambiguous, pigeons timed accurately.

  Title Imitative learning in Japanese quail (Coturnix japonica) using the bidirectional control procedure Type Journal Article
  Year 2002 Publication Animal learning & behavior Abbreviated Journal Anim Learn Behav  
  Volume 30 Issue 3 Pages 275-281  
  Keywords Animals; Attention; Behavior, Animal; Coturnix; *Discrimination Learning; *Imitative Behavior; Male; Smell  
  Abstract In the bidirectional control procedure, observers are exposed to a conspecific demonstrator responding to a manipulandum in one of two directions (e.g., left vs. right). This procedure controls for socially mediated effects (the mere presence of a conspecific) and stimulus enhancement (attention drawn to a manipulandum by its movement), and it has the added advantage of being symmetrical (the two different responses are similar in topography). Imitative learning is demonstrated when the observers make the response in the direction that they observed it being made. Recently, however, it has been suggested that when such evidence is found with a predominantly olfactory animal, such as the rat, it may result artifactually from odor cues left on one side of the manipulandum by the demonstrator. In the present experiment, we found that Japanese quail, for which odor cues are not likely to play a role, also showed significant correspondence between the direction in which the demonstrator and the observer push a screen to gain access to reward. Furthermore, control quail that observed the screen move, when the movement of the screen was not produced by the demonstrator, did not show similar correspondence between the direction of screen movement observed and that performed by the observer. Thus, with the appropriate control, the bidirectional procedure appears to be useful for studying imitation in avian species.

  Title Development of a single-code/default coding strategy in pigeons Type Journal Article
  Year 2000 Publication Psychological science : a journal of the American Psychological Society / APS Abbreviated Journal Psychol Sci  
  Volume 11 Issue 3 Pages 261-264  
  Keywords Animals; Attention; Columbidae; *Discrimination Learning; Female; Male; *Pattern Recognition, Visual; *Problem Solving; Retention (Psychology)  
  Abstract We tested the hypothesis that pigeons could use a cognitively efficient coding strategy by training them on a conditional discrimination (delayed symbolic matching) in which one alternative was correct following the presentation of one sample (one-to-one), whereas the other alternative was correct following the presentation of any one of four other samples (many-to-one). When retention intervals of different durations were inserted between the offset of the sample and the onset of the choice stimuli, divergent retention functions were found. With increasing retention interval, matching accuracy on trials involving any of the many-to-one samples was increasingly better than matching accuracy on trials involving the one-to-one sample. Furthermore, following this test, pigeons treated a novel sample as if it had been one of the many-to-one samples. The data suggest that rather than learning each of the five sample-comparison associations independently, the pigeons developed a cognitively efficient single-code/default coding strategy.

  Title Selective attention in animal discrimination learning Type Journal Article
  Year 2000 Publication The Journal of general psychology Abbreviated Journal J Gen Psychol  
  Volume 127 Issue 1 Pages 45-66  
  Keywords Animals; Attention/*physiology; Behavior, Animal/physiology; Conditioning (Psychology)/physiology; Cues; Discrimination Learning/*physiology; Generalization, Response; Rats  
  Abstract The traditional approach to the study of selective attention in animal discrimination learning has been to ask if animals are capable of the central selective processing of stimuli, such that certain aspects of the discriminative stimuli are partially or wholly ignored while their relationships to each other, or other relevant stimuli, are processed. A notable characteristic of this research has been that procedures involve the acquisition of discriminations, and the issue of concern is whether learning is selectively determined by the stimulus dimension defined by the discriminative stimuli. Although there is support for this kind of selective attention, in many cases, simpler nonattentional accounts are sufficient to explain the results. An alternative approach involves procedures more similar to those used in human information-processing research. When selective attention is studied in humans, it generally involves the steady state performance of tasks for which there is limited time allowed for stimulus input and a relatively large amount of relevant information to be processed; thus, attention must be selective or divided. When this approach is applied to animals and alternative accounts have been ruled out, stronger evidence for selective or divided attention in animals has been found. Similar processes are thought to be involved when animals search more natural environments for targets. Finally, an attempt is made to distinguish these top-down attentional processes from more automatic preattentional processes that have been studied in humans and other animals.
