	Title	Passage order through different pathways in groups of schooling fish, and the diversified leadership hypothesis			Type	Journal Article
	Year	1996	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	37	Issue	1	Pages	1-8
	Keywords	Animal sociality; Inter-individual variability; Aggregation-dispersion; Group problem solving
	Abstract	The diversified leadership hypothesis proposes that different individuals within a school of fish act as leaders in different circumstances. This `circumstantial leadership' results from inter-individual behavioral variability and a `cohesion-dispersion' tendency modulated by `failure-success' contingencies. The hypothesis predicts that when offered different pathways to escape the restriction of their swimming space, individuals within a group of fish will show 1. (a) consistent passage orders in each pathway, but2. (b) different passage orders in different pathways. Using an avoidance paddle and three different groups of fish (Aphyocharax erithrurus) the results confirmed prediction 1. (a) while prediction2. (b) was verified only in one group.

	Title	Acquisition of dominance status affects maze learning in mice			Type	Journal Article
	Year	2002	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	60	Issue	1	Pages	53-59
	Keywords	Social status; Learning; Radial maze; Mouse
	Abstract	Learning is likely to be costly and thus subject to trade-off with other components of life history. An obvious prediction, therefore, is that investment in learning, and thus learning performance, will vary with individual life history strategy and the reproductive value of the learning outcome. We tested this idea in the context of social dominance in male laboratory mice, using a simple radial maze paradigm to compare the ability of high- and low-ranking male mice to track changing food location. We tested animals in randomly selected pairs before and after establishing aggressive rank relationships to distinguish intrinsic differences in learning ability from those attributable to acquiring high or low rank. There was no difference in learning between later dominants and subordinates prior to establishing rank relationships. After pairing, however, dominants showed a significantly greater percentage of correct responses, with the difference being greatest earlier in a sequence of trials. The percentage of correct responses also increased with the amount of aggression initiated during pairing. The results thus appeared to reflect a state-dependent change in learning associated with the aggressive social relationships formed during pairing.

	Title	Comparison of social ranks based on worm-running and aggressive behaviour in young domestic fowl			Type	Journal Article
	Year	2004	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	65	Issue	1	Pages	79-86
	Keywords	Aggression; Social behaviour; Dominance; Play; Chickens; Animal welfare
	Abstract	Worm-running is behaviour in which a chick runs carrying a worm-like object while flock mates follow and attempt to grab the object from its beak. We hypothesised that social ranks based on worm-running frequency are stable over time and are positively correlated with social ranks based on success in aggressive interactions when older. At 8-12 days of age, we scored worm-running in 17 groups of 12 female White Leghorn chicks during three 10-min tests. Based on instantaneous scans at 5-s intervals, the bird carrying the `worm' most often was placed in rank one and so on down the rank order. These tests were repeated at 68-70 days of age. An aggression index for each bird was calculated as the number of aggressive acts given, divided by the number given and received, during three 1-h observation periods when the birds were 68-70 days. Ranks obtained in worm-running tests were positively correlated over the two age periods (P<0.05) but were not correlated with ranks based on the aggression index (P>0.05). Our results indicate that worm-running ranks are not predictive of success in aggressive interactions. Instead, worm-running fits some criteria for play.

	Title	The importance of `memory' in statistical models for animal feeding behaviour			Type	Journal Article
	Year	2004	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	67	Issue	1	Pages	99-109
	Keywords	Cow; Feeding data; Bouts; Memory; Satiety; Latent structure; Model comparison
	Abstract	We investigate models for animal feeding behaviour, with the aim of improving understanding of how animals organise their behaviour in the short term. We consider three classes of model: hidden Markov, latent Gaussian and semi-Markov. Each can predict the typical `clustered' feeding behaviour that is generally observed, however they differ in the extent to which `memory' of previous behaviour is allowed to affect future behaviour. The hidden Markov model has `lack of memory', the current behavioural state being dependent on the previous state only. The latent Gaussian model assumes feeding/non-feeding periods to occur by the thresholding of an underlying continuous variable, thereby incorporating some `short-term memory'. The semi-Markov model, by taking into account the duration of time spent in the previous state, can be said to incorporate `longer-term memory'. We fit each of these models to a dataset of cow feeding behaviour. We find the semi-Markov model (longer-term memory) to have the best fit to the data and the hidden Markov model (lack of memory) the worst. We argue that in view of effects of satiety on short-term feeding behaviour of animal species in general, biologically suitable models should allow `memory' to play a role. We conclude that our findings are equally relevant for the analysis of other types of short-term behaviour that are governed by satiety-like principles.

	Title	Response acquisition with immediate and delayed conditioned reinforcement			Type	Journal Article
	Year	2005	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	68	Issue	1	Pages	1-11
	Keywords	Response acquisition; Conditioned reinforcement; Delayed reinforcement; Secondary reinforcement; Rats
	Abstract	Groups comprising eight rats initially were exposed to response-independent water deliveries, then to conditions under which a lever-press response raised an empty dipper immediately or after a resetting delay of 15, 30, or 45 s. When their performance was compared to that of control animals using a 90% confidence level, six rats in the immediate-reinforcement group met the primary criterion for response acquisition during a single 6-h session; 4, 4, and 3 did so in the 15, 30, and 45 s delay groups, respectively. Similar evidence of acquisition was obtained when a 95% confidence level was used. With a 99% confidence level, however, evidence of acquisition was not compelling. Although these data appear to provide the first demonstration of response acquisition in the absence of handshaping or autoshaping under conditions where the putative reinforcer is both conditioned and delayed, they also demonstrate that whether response acquisition occurs depends, in part, on how it is defined.

	Title	Acquisition, extinction, and reacquisition of responding with delayed and immediate reinforcement			Type	Journal Article
	Year	1998	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	43	Issue	1	Pages	97-101
	Keywords	Acquisition; Delayed reinforcement; Extinction; Rats
	Abstract	The present study investigated acquisition, extinction, and reacquisition of free-operant responding when rats' lever presses produced water after a resetting delay of 0, 10, 20, or 30 s. Results indicated that: (1) responding was acquired rapidly at all delays without shaping or autoshaping; (2) resistance to extinction was directly related to delay length and inversely related to intermittency of reinforcement; (3) responding acquired with delayed reinforcement recovered less rapidly from extinction, and was less efficient, than responding acquired with immediate reinforcement. Comparing these results with those of studies using discrete-trials and free-operant procedures with no reinforcement delay suggest that the specific conditions under which behavior is maintained determines, in part, the behavioral effects of delay and intermittency of reinforcement.

	Title	A note on the responses of chimpanzees (Pan troglodytes) to live self-images on television monitors			Type	Journal Article
	Year	2007	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	75	Issue	1	Pages	85-90
	Keywords	Animals; Discrimination Learning; Female; Male; Pan troglodytes/psychology; *Self Concept; Self Psychology; Social Behavior; Television
	Abstract	The majority of studies on self-recognition in animals have been conducted using a mirror as the test device; little is known, however, about the responses of non-human primates toward their own images in media other than mirrors. This study provides preliminary data on the reactions of 10 chimpanzees to live self-images projected on two television monitors, each connected to a different video camera. Chimpanzees could see live images of their own faces, which were approximately life-sized, on one monitor. On the other monitor, they could see live images of their whole body, which were approximately one-fifth life-size, viewed diagonally from behind. In addition, several objects were introduced into the test situation. Out of 10 chimpanzees tested, 2 individuals performed self-exploratory behaviors while watching their own images on the monitors. One of these two chimpanzees successively picked up two of the provided objects in front of a monitor, and watched the images of these objects on the monitor. The results indicate that these chimpanzees were able to immediately recognize live images of themselves or objects on the monitors, even though several features of these images differed from those of their previous experience with mirrors.
