	Title	Observational learning of two visual discriminations by pigeons: a within-subjects design			Type	Journal Article
	Year	1986	Publication	Journal of the experimental analysis of behavior	Abbreviated Journal	J Exp Anal Behav
	Volume	46	Issue	1	Pages	45-49
	Keywords	Animals; Attention; Columbidae; Conditioning, Operant; Cues; Discrimination Learning; Imitative Behavior; Male; Visual Perception
	Abstract	Pigeon's observational learning of successive visual discrimination was studied using within-subject comparisons of data from three experimental conditions. Two pairs of discriminative stimuli were used; each bird was exposed to two of the three experimental conditions, with different pairs of stimuli used in a given bird's two conditions. In one condition, observers were exposed to visual discriminative stimuli only. In a second condition, subjects were exposed to a randomly alternating sequence of two stimuli where the one that would subsequently be used as S+ was paired with the operation of the grain magazine. In a third experimental condition, subjects were exposed to the performance of a conspecific in the operant discrimination procedure. After exposures to conspecific performances, there was facilitation of discriminative learning, relative to that which followed exposures to stimulus and reinforcement sequences or exposures to stimulus sequences alone. Exposure to stimulus and food-delivery sequences enhanced performance relative to exposure to stimulus sequences alone. The differential effects of these three types of exposure were not attributable to order effects or to task difficulty; rather, they clearly were due to the type of exposure.

	Title	Effects of neophobia and habituation on the poison-induced avoidance of exteroceptive stimuli in the rat			Type	Journal Article
	Year	1975	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	1	Issue	1	Pages	47-55
	Keywords	Animals; Avoidance Learning/drug effects; Awareness; Cognition; Conditioning, Operant; Feeding Behavior/drug effects; Habituation, Psychophysiologic; Injections, Intraperitoneal; Lithium/administration & dosage/poisoning; Male; Rats; Taste; Time Factors; Visual Perception
	Abstract	Two experiments on the role of neophobia in poison-induced aversions to exteroceptive stimuli are reported. In Experiment 1, rats were given either 10 or 25 days of habituation to the test situation prior to conditioning. Those animals with the longer habituation period avoided a complex of novel exteroceptive stimuli while those with the shorter habituation period did not. In Experiment 2 rats initially avoided the more novel of two containers, but gradually came to eat equal amounts from both. A single pairing of toxicosis with consumption from either the novel or the familiar container reinstated the avoidance of the novel container in both cases. The results were discussed in terms of an interaction between habituation and conditioning procedures. It was suggested that previously reported differences between interoceptive and exteroceptive conditioning effects may have been influenced by the differential novelty of the two classes of stimuli in the test situation. It was further suggested that non-contingently poisoned control groups should routinely be included in poison avoidance conditioning studies.

	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.

	Title	Support for a theory of memory for event duration must distinguish between test-trial ambiguity and actual memory loss			Type	Journal Article
	Year	1999	Publication	Journal of the experimental analysis of behavior	Abbreviated Journal	J Exp Anal Behav
	Volume	72	Issue	3	Pages	467-472
	Keywords	Animals; Behavior, Animal/physiology; Columbidae; Conditioning, Operant/physiology; Discrimination Learning/physiology; Memory/physiology; Psychological Theory; Time Factors; Time Perception/physiology
	Abstract	Staddon and Higa's (1999) trace-strength theory of timing and memory for event duration can account for pigeons' bias to “choose short” when retention intervals are introduced and to “choose long” when, following training with a fixed retention interval, retention intervals are shortened. However, it does not account for the failure of pigeons to choose short when the intertrial interval is distinct from the retention interval. That finding suggests that stimulus generalization (or ambiguity) between the intertrial interval and the retention interval may result in an effect that has been attributed to memory loss. Such artifacts must be eliminated before a theory of memory for event duration can be adequately tested.

	Title	What-where-when memory in pigeons			Type	Journal Article
	Year	2006	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	4	Pages	345-358
	Keywords	Animals; Behavior, Animal/physiology; Columbidae; Conditioning, Operant/physiology; Memory/physiology; Reinforcement (Psychology); Space Perception/physiology; Spatial Behavior/physiology; Teaching; Visual Perception/physiology
	Abstract	The authors report a novel approach to testing episodic-like memory for single events. Pigeons were trained in separate sessions to match the identity of a sample on a touch screen, to match its location, and to report on the length of the retention interval. When these 3 tasks were mixed randomly within sessions, birds were more than 80% correct on each task. However, performance on 2 different tests in succession after each sample was not consistent with an integrated memory for sample location, time, and identity. Experiment 2 tested binding of location and identity memories in 2 different ways. The results were again consistent with independent feature memories. Implications for tests of episodic-like memory are discussed.

	Title	Reinforced variability in animals and people: implications for adaptive action			Type	Journal Article
	Year	2004	Publication	The American Psychologist	Abbreviated Journal	Am Psychol
	Volume	59	Issue	9	Pages	891-906
	Keywords	Animals; Behavior, Animal; Choice Behavior; Conditioning, Operant; Creativeness; Discrimination (Psychology); Humans; Memory; Problem Solving; Reinforcement (Psychology)
	Abstract	Although reinforcement often leads to repetitive, even stereotyped responding, that is not a necessary outcome. When it depends on variations, reinforcement results in responding that is diverse, novel, indeed unpredictable, with distributions sometimes approaching those of a random process. This article reviews evidence for the powerful and precise control by reinforcement over behavioral variability, evidence obtained from human and animal-model studies, and implications of such control. For example, reinforcement of variability facilitates learning of complex new responses, aids problem solving, and may contribute to creativity. Depression and autism are characterized by abnormally repetitive behaviors, but individuals afflicted with such psychopathologies can learn to vary their behaviors when reinforced for so doing. And reinforced variability may help to solve a basic puzzle concerning the nature of voluntary action.

	Title	Cognitive precedence for local information in hierarchical stimulus processing by pigeons			Type	Journal Article
	Year	2001	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	27	Issue	1	Pages	3-16
	Keywords	Animals; Behavior, Animal; Cognition; Columbidae; Conditioning, Operant; Male
	Abstract	Four experiments investigated the processing of hierarchical stimuli by pigeons. Using a 4 alternative divided-attention task, 4 pigeons were food-reinforced for accurately identifying letters arranged as either hierarchical global- or local-relevant stimuli or as size-matched filled stimuli. Experiment 1 found that task acquisition was faster with local-relevant than global-relevant stimuli. This difference was not due to letter size. Experiment 2 demonstrated successful transfer to a novel irrelevant letter configuration. Experiments 3 and 4 tested pigeons' responses to conflict probe stimuli composed of equally discriminable relevant letters at each level. These tests revealed that all of the pigeons showed a cognitive precedence for local information early in processing, with the pigeons using different cues to initiate the processing of global information. This local advantage contrasts with previously reported results for humans and pigeons but is similar to that reported for nonhuman primates. Alternatives attempting to reconcile these contrasting comparative results are considered.

	Title	Temporal parameters of the feature positive effect			Type	Journal Article
	Year	1979	Publication	The American journal of psychology	Abbreviated Journal	Am J Psychol
	Volume	92	Issue	4	Pages	703-710
	Keywords	Animals; Columbidae; Conditioning, Operant; Discrimination Learning; Form Perception; Male; Time Perception
	Abstract	Trial duration and intertrial interval duration were parametrically varied between groups of pigeons exposed to a discrimination involving the presence vs. the absence of a dot. Half the groups received the dot as the positive stimulus (feature positive groups) and half the groups received the dot as the negative stimulus (feature negative groups). Faster learning by the feature positive birds (feature positive effect) was found when the trial duration was short (5 sec) regardless of whether the intertrial interval was short (5 sec) or long (30 sec). No evidence for a feature positive effect was found when the trial duration was long (30 sec) regardless of the length of the intertrial interval (30 sec or 180 sec). The results suggest that short trial duration is a necessary condition for the occurrence of the feature positive effect, and neither intertrial interval nor trial duration/intertrial interval ratio are important for its occurrence. The suggestion that mechanisms underlying the feature positive effect and autoshaping might be similar was not supported by the present experiment since the trial duration/intertrial interval ration parameter appears to play an important role in autoshaping but not the feature positive effect.

	Title	Temporal landmarks: proximity prevails			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	2	Pages	113-120
	Keywords	Animals; Columbidae; Conditioning, Operant; Reaction Time; *Time Perception
	Abstract	Subjects in conditioning experiments time their conditioned responses relative to the onsets of the conditioned stimuli (CSs). These onsets are temporal landmarks, by reference to which subjects may estimate the location of the unconditioned stimulus (US) in time. In a serial compound conditioning paradigm, a long duration CS comes on first, followed later by a second shorter CS, creating both a long-range and a short-range predictor of the US. We ask whether displacing the short-range predictor relative to the long-range predictor causes subjects to strike a compromise between the different temporal locations predicted by the two CSs. In three experiments with pigeons, we varied the training conditions so as to favor or militate against this outcome. However, in all conditions, there was no compromise; after the onset of the displaced short-range CS, the timing of conditioned responding was governed by it alone. This result contrasts with the compromises that are seen when the feeding time predicted by a CS is put in conflict with the time predicted by the circadian clock, and with the similar compromises sometimes seen when a nearby spatial landmark is displaced relative to a larger spatial context.
