	Title	Second-order contrast based on the expectation of effort and reinforcement			Type	Journal Article
	Year	2002	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	28	Issue	1	Pages	64-74
	Keywords	Animals; Columbidae; Discrimination Learning; Random Allocation; *Reinforcement (Psychology)
	Abstract	Pigeons prefer signals for reinforcement that require greater effort (or time) to obtain over those that require less effort to obtain (T. S. Clement, J. Feltus, D. H. Kaiser, & T. R. Zentall, 2000). Preference was attributed to contrast (or to the relatively greater improvement in conditions) produced by the appearance of the signal when it was preceded by greater effort. In Experiment 1, the authors of the present study demonstrated that the expectation of greater effort was sufficient to produce such a preference (a second-order contrast effect). In Experiments 2 and 3, low versus high probability of reinforcement was substituted for high versus low effort, respectively, with similar results. In Experiment 3, the authors found that the stimulus preference could be attributed to positive contrast (when the discriminative stimuli represented an improvement in the probability of reinforcement) and perhaps also negative contrast (when the discriminative stimuli represented reduction in the probability of reinforcement).

	Title	Selective suppression of drinking during a limited period following aversive drug treatment in rats			Type	Journal Article
	Year	1977	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	3	Issue	1	Pages	66-76
	Keywords	Animals; Avoidance Learning; Awareness; Conditioning, Operant; Dose-Response Relationship, Drug; Drinking Behavior/drug effects; Lithium/poisoning; Male; Osmolar Concentration; Rats; Saccharin/administration & dosage; Taste; Time Factors
	Abstract	Administration of lithium chloride disrupted the intake of flavored solutions but not water in rats. This intake suppression was directly related to the amount of lithium administered (Experiment 1), occurred with both palatable and unpalatable novel saccharin solutions (Experiment 2), but was only observed if subjects were tested starting less than 75 min. after lithium treatment (Experiment 3). Twenty-five daily exposures to saccharin did not attenuate the effect (Experiment 4). However, in saccharin-reared and vinegar-reared rats, lithium did not disrupt consumption of the solutions these subjects had access to throughout life, even though suppressions of intake were observed when these subjects were tested with novel flavors (Experiment 5). The selective disruption of drinking is interpreted as a novelty-dependent sensitization reaction to the discomfort of aversive drug administration.

	Title	Sequential responding and planning in chimpanzees (Pan troglodytes) and rhesus macaques (Macaca mulatta)			Type	Journal Article
	Year	2004	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	30	Issue	3	Pages	203-212
	Keywords	Animals; Cognition; Female; Goals; Learning; Macaca mulatta/psychology; Male; Mathematics; Pan troglodytes/psychology; Task Performance and Analysis
	Abstract	Chimpanzees (Pan troglodytes) and rhesus macaques (Macaca mulatta) selected either Arabic numerals or colored squares on a computer monitor in a learned sequence. On shift trials, the locations of 2 stimuli were interchanged at some point. More errors were made when this interchange occurred for the next 2 stimuli to be selected than when the interchange was for stimuli later in the sequence. On mask trials, all remaining stimuli were occluded after the 1st selection. Performance exceeded chance levels for only 1 selection after these masks were applied. There was no difference in performance for either stimulus type (numerals or colors). The data indicated that the animals planned only the next selection during these computerized tasks as opposed to planning the entire response sequence.

	Title	Standard delay eyeblink classical conditioning is independent of awareness			Type	Journal Article
	Year	2002	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	28	Issue	1	Pages	32-37
	Keywords	Aged; Awareness; Blinking; *Conditioning, Classical; Humans
	Abstract	P. F. Lovibond and D. R. Shanks (2002) suggested that all forms of classical conditioning depend on awareness of the stimulus contingencies. This article considers the available data for eyeblink classical conditioning, including data from 2 studies (R. E. Clark, J. R. Manns, & L. R. Squire, 2001; J. R. Manns, R. E. Clark, & L. R. Squire, 2001) that were completed too recently to have been considered in their review. In addition, in response to questions raised by P. F. Lovibond and D. R. Shanks, 2 new analyses of data are presented from studies published previously. The available data from humans and experimental animals provide strong evidence that delay eyeblink classical conditioning (but not trace eyeblink classical conditioning) can be acquired and retained independently of the forebrain and independently of awareness. This conclusion applies to standard conditioning paradigms; for example, to single-cue delay conditioning when a tone is used as the conditioned stimulus (CS) and to differential delay conditioning when the positive and negative conditioned stimuli (CS+ and CS-) are a tone and white noise.

	Title	Summation in the chimpanzee (Pan troglodytes)			Type	Journal Article
	Year	1987	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	13	Issue	2	Pages	107-115
	Keywords	Animals; Choice Behavior; Cognition; Male; Mathematics; *Pan troglodytes; Visual Perception
	Abstract	In this research, we asked whether 2 chimpanzee (Pan troglodytes) subjects could reliably sum across pairs of quantities to select the greater total. Subjects were allowed to choose between two trays of chocolates. Each tray contained two food wells. To select the tray containing the greater number of chocolates, it was necessary to sum the contents of the food wells on each tray. In experiments where food wells contained from zero to four chocolates, the chimpanzees chose the greater value of the summed wells on more than 90% of the trials. In the final experiment, the maximum number of chocolates assigned to a food well was increased to five. Choice of the tray containing the greater sum still remained above 90%. In all experiments, subjects reliably chose the greater sum, even though on many trials a food well on the “incorrect” tray held more chocolates than either single well on the “correct” tray. It was concluded that without any known ability to count, these chimpanzees used some process of summation to combine spatially separated quantities. Speculation regarding the basis for summation includes consideration of perceptual fusion of pairs of quantities and subitization.

	Title	Systematic nonlinearities in the perception of temporal intervals			Type	Journal Article
	Year	1999	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	25	Issue	1	Pages	3-17
	Keywords	Animals; Attention; Awareness; Discrimination Learning; Male; Neural Networks (Computer); Nonlinear Dynamics; Rats; Rats, Sprague-Dawley; Sensory Thresholds; *Time Perception
	Abstract	Rats judged time intervals in a choice procedure in which accuracy was maintained at approximately 75% correct. Sensitivity to time (d') was approximately constant for short durations 2.0-32.0 s with 1.0- or 2.0-s spacing between intervals (n = 5 in each group, Experiment 1), 2.0-50.0 s with 2.0-s spacing (n = 2, Experiment 1), and 0.1-2.0 s with 0.1- or 0.2-s spacing (n = 6 in each group, Experiment 2). However, systematic departures from average sensitivity were observed, with local maxima in sensitivity at approximately 0.3, 1.2, 10.0, 24.0, and 36.0 s. Such systematic departures from an approximately constant d' are predicted by a connectionist theory of time with multiple oscillators and may require a modification of the linear timing hypothesis of scalar timing theory.

	Title	The pigeon's recognition of drawings of depth-rotated stimuli			Type	Journal Article
	Year	1996	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	22	Issue	2	Pages	205-221
	Keywords	Animals; Cognition/physiology; Columbidae; Discrimination (Psychology); Form Perception/physiology; Learning/*physiology; Photic Stimulation; Rotation
	Abstract	Four experiments used a four-choice discrimination learning paradigm to explore the pigeon's recognition of line drawings of four objects (an airplane, a chair, a desk lamp, and a flashlight) that were rotated in depth. The pigeons reliably generalized discriminative responding to pictorial stimuli over all untrained depth rotations, despite the bird's having been trained at only a single depth orientation. These generalization gradients closely resembled those found in prior research that used other stimulus dimensions. Increasing the number of different vantage points in the training set from one to three broadened the range of generalized testing performance, with wider spacing of the training orientations more effectively broadening generalized responding. Template and geon theories of visual recognition are applied to these empirical results.

	Title	The role of reference points in ordinal numerical comparisons by rhesus macaques (Macaca mulatta)			Type	Journal Article
	Year	2006	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	2	Pages	120-134
	Keywords	Animals; Cognition; Discrimination (Psychology); Generalization (Psychology); Macaca mulatta/psychology; Male; Mathematics; *Pattern Recognition, Visual
	Abstract	Two experiments examined ordinal numerical knowledge in rhesus macaques (Macaca mulatta). Experiment 1 replicated the finding (E. M. Brannon & H. S. Terrace, 2000) that monkeys trained to respond in descending numerical order (4-->3-->2-->1) did not generalize the descending rule to the novel values 5-9 in contrast to monkeys trained to respond in ascending order. Experiment 2 examined whether the failure to generalize a descending rule was due to the direction of the training sequence or to the specific values used in the training sequence. Results implicated 3 factors that characterize a monkey's numerical comparison process: Weber's law, knowledge of ordinal direction, and a comparison of each value in a test pair with the reference point established by the first value of the training sequence.

	Title	The science of animal cognition: past, present, and future			Type	Journal Article
	Year	1997	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	23	Issue	2	Pages	123-135
	Keywords	Animal Communication; Animal Population Groups/psychology; Animals; Behavior, Animal; Behavioral Sciences/trends; *Cognition; Evolution; Forecasting; Humans; Intelligence
	Abstract	The field of animal cognition is strongly rooted in the philosophy of mind and in the theory of evolution. Despite these strong roots, work during the most famous and active period in the history of our science-the 1930s, 1940s, and 1950s-may have diverted us from the very questions that were of greatest initial interest to the comparative analysis of learning and behavior. Subsequently, the field has been in steady decline despite its increasing breadth and sophistication. Renewal of the field of animal cognition may require a return to the original questions of animal communication and intelligence using the most advanced tools of modern psychological science. Reclaiming center stage in contemporary psychology will be difficult; planning that effort with a host of strategies should enhance the chances of success.

	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.
