Title	Choice based on exclusion in pigeons			Type	Journal Article
Year	2003	Publication	Psychonomic bulletin & review	Abbreviated Journal	Psychon Bull Rev
Volume	10	Issue	4	Pages	959-964
Keywords	Animals; Appetitive Behavior; Association Learning; Choice Behavior; Color Perception; Columbidae; Discrimination Learning; Memory, Short-Term; *Problem Solving; Psychomotor Performance; Reaction Time; Transfer (Psychology)
Abstract	When humans acquire a conditional discrimination and are given a novel-sample-comparison choice, they often reject a comparison known to be associated with a different sample and choose the alternative comparison by default (or by exclusion). In Experiment 1, we found that if, following matching training, we replaced both of the samples, acquisition took five times longer than if we replaced only one of the samples. Apparently, the opportunity to reject one of the comparisons facilitated the association of the other sample with the remaining comparison. In Experiment 2, we first trained pigeons to treat two samples differently (to associate Sample A with Comparison 1 and Sample B with Comparison 2) and then trained them to associate one of those samples with a new comparison (e.g., Sample A with Comparison 3) and to associate a novel sample (Sample C) with a different, new comparison (Comparison 4). When Sample B then replaced Sample C, the pigeons showed a significant tendency to choose Comparison 4 over Comparison 3. Thus, when given the opportunity, pigeons will choose by exclusion.

Title	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	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 New Caledonian crow (Corvus moneduloides) creatively re-designs tools by bending or unbending aluminium strips			Type	Journal Article
Year	2006	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
Volume	9	Issue	4	Pages	317-334
Keywords	Animals; Comprehension; Crows; Female; Learning; Motor Skills; Problem Solving; *Tool Use Behavior
Abstract	Previous observations of a New Caledonian crow (Corvus moneduloides) spontaneously bending wire and using it as a hook [Weir et al. (2002) Science 297:981] have prompted questions about the extent to which these animals 'understand' the physical causality involved in how hooks work and how to make them. To approach this issue we examine how the same subject (“Betty”) performed in three experiments with novel material, which needed to be either bent or unbent in order to function to retrieve food. These tasks exclude the possibility of success by repetition of patterns of movement similar to those employed before. Betty quickly developed novel techniques to bend the material, and appropriately modified it on four of five trials when unbending was required. She did not mechanically apply a previously learned set of movements to the new situations, and instead sought new solutions to each problem. However, the details of her behaviour preclude concluding definitely that she understood and planned her actions: in some cases she probed with the unmodified tools before modifying them, or attempted to use the unmodified (unsuitable) end of the tool after modification. Gauging New Caledonian crows' level of understanding is not yet possible, but the observed behaviour is consistent with a partial understanding of physical tasks at a level that exceeds that previously attained by any other non-human subject, including apes.

Title	The right tool for the job: what strategies do wild New Caledonian crows use?			Type	Journal Article
Year	2006	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
Volume	9	Issue	4	Pages	307-316
Keywords	Analysis of Variance; Animals; Comprehension; Crows; Female; Intelligence; Male; Problem Solving; Tool Use Behavior
Abstract	New Caledonian crows Corvus moneduloides (NC crows) display sophisticated tool manufacture in the wild, but the cognitive strategy underlying these skills is poorly understood. Here, we investigate what strategy two free-living NC crows used in response to a tool-length task. The crows manufactured tools to extract food from vertical holes of different depths. The first tools they made in visits were of a similar length regardless of the hole depth. The typical length was usually too short to extract food from the deep holes, which ruled out a strategy of immediate causal inference on the first attempt in a trial. When the first tool failed, the crows made second tools significantly longer than the unsuccessful first tools. There was no evidence that the crows made the lengths of first tools to directly match hole depth. We argue that NC crows may generally use a two-stage heuristic strategy to solve tool problems and that performance on the first attempt in a trial is not necessarily the 'gold standard' for assessing folk physics.

Title	Technical intelligence in animals: the kea model			Type	Journal Article
Year	2006	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
Volume	9	Issue	4	Pages	295-305
Keywords	Animals; Comprehension; Intelligence; Models, Psychological; Observation; Parrots; Problem Solving; Psychological Theory; Social Environment; *Tool Use Behavior
Abstract	The ability to act on information flexibly is one of the cornerstones of intelligent behavior. As particularly informative example, tool-oriented behavior has been investigated to determine to which extent nonhuman animals understand means-end relations, object affordances, and have specific motor skills. Even planning with foresight, goal-directed problem solving and immediate causal inference have been a focus of research. However, these cognitive abilities may not be restricted to tool-using animals but may be found also in animals that show high levels of curiosity, object exploration and manipulation, and extractive foraging behavior. The kea, a New Zealand parrot, is a particularly good example. We here review findings from laboratory experiments and field observations of keas revealing surprising cognitive capacities in the physical domain. In an experiment with captive keas, the success rate of individuals that were allowed to observe a trained conspecific was significantly higher than that of naive control subjects due to their acquisition of some functional understanding of the task through observation. In a further experiment using the string-pulling task, a well-probed test for means-end comprehension, we found the keas finding an immediate solution that could not be improved upon in nine further trials. We interpreted their performance as insightful in the sense of being sensitive of the relevant functional properties of the task and thereby producing a new adaptive response without trial-and-error learning. Together, these findings contribute to the ongoing debate on the distribution of higher cognitive skills in the animal kingdom by showing high levels of sensorimotor intelligence in animals that do not use tools. In conclusion, we suggest that the 'Technical intelligence hypothesis' (Byrne, Machiavellian intelligence II: extensions and evaluations, pp 289-211, 1997), which has been proposed to explain the origin of the ape/monkey grade-shift in intelligence by a selection pressure upon an increased efficiency in foraging behavior, should be extended, that is, applied to some birds as well.

Title	“Insightful” string-pulling in Grey parrots (Psittacus erithacus) is affected by vocal competence			Type	Journal Article
Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
Volume	7	Issue	4	Pages	263-266
Keywords	Animals; Association Learning; Discrimination Learning; Humans; Male; Parrots; Problem Solving; Verbal Behavior; Verbal Learning; *Vocalization, Animal
Abstract	Four Grey parrots (Psittacus erithacus) were tested on their ability to obtain an item suspended from a string such that mutiple, repeated, coordinated beak-foot actions were required for success (e.g., Heinrich 1995). Those birds with little training in referential English requests (e.g. “I want X”) succeeded, whereas birds who could request the suspended item failed to obtain the object but engaged in repeated requesting.

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.
