	Title	How marsh tits find their hoards: the roles of site preference and spatial memory			Type	Journal Article
	Year	1982	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	8	Issue	4	Pages	354-375
	Keywords	Animals; Appetitive Behavior; Birds; Cues; Discrimination Learning; Memory; Mental Recall; Orientation; *Space Perception
	Abstract	Marsh tits (Parus palustris) store single food items in scattered locations and recover them hours or days later. Some properties of the spatial memory involved were analyzed in two laboratory experiments. In the first, marsh tits were offered 97 sites for storing 12 seeds. They recovered a median of 65% of them 2-3 hr later, making only two errors per seed while doing so. Over trials, they used some sites more often than others, but during recovery they were more likely to visit a site of any preference value if they had stored a seed there that day than if they had not. Recovery performance was much worse if the experimenters moved the seeds between storage and recovery. A fixed search strategy that had some of the same average properties as the tits' search behavior also did worse than the real birds. In Experiment 2, any tendency to visit the same sites on successive daily tests in the aviary was placed in opposition to memory for storage sites by allowing the tits to store more seeds 2 hr after storing a first batch. They tended to avoid individual storage sites holding seeds from the first batch. When the tits searched for all the seeds 2 hr later, they tended to recover more seeds from the second batch than from the first, i.e., there was a recency effect.

	Title	Reinforcement and the organization of behavior in golden hamsters: brain stimulation reinforcement for seven action patterns			Type	Journal Article
	Year	1980	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	6	Issue	4	Pages	352-375
	Keywords	Animals; Behavior, Animal/physiology; Cricetinae; Electric Stimulation; Female; Hypothalamus/physiology; Male; Medial Forebrain Bundle/physiology; Mesocricetus; *Reinforcement (Psychology)
	Abstract	Golden hamsters were reinforced with intracranial electrical stimulation of the lateral hypothalamus (ICS) for spending time engaging in one of seven topographically defined action patterns (APs). The stimulation used as reinforcer elicited hoarding and/or feeding and supported high rates of bar pressing. In Experiment 1, hamsters were reinforced successively for digging, open rearing, and face washing. Digging increased most in time spent, and face washing increased least. Experiments 2-5 examined these effects further and also showed that “scrabbling,” like digging, was performed a large proportion of the time, almost without interruption, for contingent ICS but that scratching the body with a hindleg and scent-marking showed relatively little effect of contingent ICS, the latter even in an environment that facilitated marking. In Experiment 6, naive hamsters received ICS not contingent on behavior every 30 sec (fixed-time 30-sec schedule). Terminal behaviors that developed on this schedule were APs that were easy to reinforce in the other experiments, but a facultative behavior, face washing, was one not so readily reinforced. Experiment 7 confirmed a novel prediction from Experiment 6--that wall rearing, a terminal AP, would be performed at a high level for contingent ICS. All together, the results point to both motivational factors and associative factors being involved in the considerable differences in performance among different reinforced activities.

	Title	Reinforcement and the organization of behavior in golden hamsters: Pavlovian conditioning with food and shock unconditioned stimuli			Type	Journal Article
	Year	1978	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	4	Issue	2	Pages	152-169
	Keywords	Acoustic Stimulation; Animals; Behavior, Animal; Conditioning, Classical; Conditioning, Operant; Cricetinae; Electroshock; Female; Food; Male; Punishment; *Reinforcement (Psychology); Reinforcement Schedule
	Abstract	The effects of Pavlovian conditioned stimuli (CSs) for food or shock on a variety of behaviors of golden hamsters were observed in three experiments. The aim was to see whether previously reported differences among the behaviors produced by food reinforcement and punishment procedures could be accounted for by differential effects of Pavlovian conditioning on the behaviors. There was some correspondence between the behaviors observed to the CSs and the previously reported effects of instrumental training. However, the Pavlovian conditioned responses (CRs) alone would not have predicted the effects of instrumental training. Moreover, CRs depended to some extent on the context in which training and testing occurred. These findings, together with others in the literature, suggest that the results of Pavlovian conditioning procedures may not unambiguously predict what system of behaviors will be most readily modified by instrumental training with a given reinforcer.

	Title	Behavioral adaptation to fixed-interval and fixed-time food delivery in golden hamsters			Type	Journal Article
	Year	1977	Publication	Journal of the Experimental Analysis of Behavior (JEAB)	Abbreviated Journal	J Exp Anal Behav
	Volume	27	Issue	1	Pages	33-49
	Keywords
	Abstract	Food-deprived golden hamsters in a large enclosure received food every 30 sec contingent on lever pressing, or free while their behavior was continuously recorded in terms of an exhaustive classification of motor patterns. As with other species in other situations, behavior became organized into two main classes. One (terminal behaviors) increased in probability throughout interfood intervals; the other (interim behaviors) peaked earlier in interfood intervals. Which class an activity belonged to was independent of whether food was contingent on lever pressing. When food was omitted on some of the intervals (thwarting), the terminal activities began sooner in the next interval, and different interim activities changed in different ways. The interim activities did not appear to be schedule-induced in the usual sense. Rather, the hamsters left the area of the feeder when food was not due and engaged in activities they would normally perform in the experimental environment.

	Title	Animal cognition and animal behaviour			Type	Journal Article
	Year	2001	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	61	Issue	2	Pages	277-286
	Keywords
	Abstract	Cognitive processes such as perception, learning, memory and decision making play an important role in mate choice, foraging and many other behaviours. In this review, I summarize a few key ideas about animal cognition developed in a recent book (Shettleworth 1998, Cognition, Evolution and Behaviour) and briefly review some areas in which interdisciplinary research on animal cognition is currently proving especially productive. Cognition, broadly defined, includes all ways in which animals take in information through the senses, process, retain and decide to act on it. Studying animal cognition does not entail any particular position on whether or to what degree animals are conscious. Neither does it entail rejecting behaviourism in that one of the greatest challenges in studing animal cognition is to formulate clear behavioural criteria for inferring specific mental processes. Tests of whether or not apparently goal-directed behaviour is controlled by a representation of its goal, episodic-like memory in birds, and deceptive behaviour in monkeys provide examples. Functional modelling has been integrated with analyses of cognitive mechanisms in a number of areas, including studies of communication, models of how predator learning and attention affect the evolution of conspicuous and cryptic prey, tests of the relationship betweeen ecological demands on spatial cognition and brain evolution, and in research on social learning. Rather than a `new field' of cognitive ecology, such interdisciplinary research on animal cognition exemplifies a revival of interest in proximate mechanisms of behaviour.
