	Title	The hippocampus and memory for orderly stimulus relations			Type	Journal Article
	Year	1997	Publication	Proceedings of the National Academy of Sciences of the United States of America	Abbreviated Journal	Proc. Natl. Acad. Sci. U.S.A.
	Volume	94	Issue	13	Pages	7109-7114
	Keywords	Animals; Attention; Discrimination (Psychology)/physiology; Hippocampus/anatomy & histology/physiology; Male; Memory/physiology; Rats
	Abstract	Human declarative memory involves a systematic organization of information that supports generalizations and inferences from acquired knowledge. This kind of memory depends on the hippocampal region in humans, but the extent to which animals also have declarative memory, and whether inferential expression of memory depends on the hippocampus in animals, remains a major challenge in cognitive neuroscience. To examine these issues, we used a test of transitive inference pioneered by Piaget to assess capacities for systematic organization of knowledge and logical inference in children. In our adaptation of the test, rats were trained on a set of four overlapping odor discrimination problems that could be encoded either separately or as a single representation of orderly relations among the odor stimuli. Normal rats learned the problems and demonstrated the relational memory organization through appropriate transitive inferences about items not presented together during training. By contrast, after disconnection of the hippocampus from either its cortical or subcortical pathway, rats succeeded in acquiring the separate discrimination problems but did not demonstrate transitive inference, indicating that they had failed to develop or could not inferentially express the orderly organization of the stimulus elements. These findings strongly support the view that the hippocampus mediates a general declarative memory capacity in animals, as it does in humans.

	Title	Attention in common marmosets: implications for social-learning experiments			Type	Journal Article
	Year	2007	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	73	Issue	6	Pages	1033-1041
	Keywords	attention; Callithrix jacchus; common marmoset; imitation; social learning
	Abstract	The question whether a certain species is or is not able to imitate has received much recent attention. However, the ability to copy a demonstrated action might depend not only on the imitative ability of the observer but also on its attention, a factor widely neglected in discussions and experiments. Since attention differs between species as well as between individuals, it is likely to influence the amount and type of information different species and/or observers may extract from a given demonstration. We studied attention in common marmosets, Callithrix jacchus. In a series of experimental sessions, individual marmosets watched different conspecific models that were searching, manipulating an object and feeding. The observers could see the demonstration through two observation holes, which allowed us to measure exactly how often and for how long they watched the model. Marmosets were more attentive towards conspecifics engaged in a problem-solving task than an exploring model. Individual variation in attention was large, ranging from less than 10% to over 49%. Attention also depended on the identity of the model with an increase in attention if it was of the opposite sex. Overall, attention of marmosets was short with a median duration of 6 s while the model manipulated an object. This study measured the real interest of the observer towards a model, which could be an important variable in social-learning experiments.

	Title	Hippocampus and memory in a food-storing and in a nonstoring bird species			Type	Journal Article
	Year	1996	Publication	Behavioral neuroscience	Abbreviated Journal	Behav Neurosci
	Volume	110	Issue	5	Pages	946-964
	Keywords	Animals; Appetitive Behavior/physiology; Attention/physiology; Birds/physiology; Brain Mapping; Feeding Behavior/physiology; Mental Recall/physiology; Organ Size/physiology; Orientation/*physiology; Retention (Psychology)/physiology; Species Specificity
	Abstract	Food-storing birds maintain in memory a large and constantly changing catalog of the locations of stored food. The hippocampus of food-storing black-capped chickadees (Parus atricapillus) is proportionally larger than that of nonstoring dark-eyed juncos (Junco hyemalis). Chickadees perform better than do juncos in an operant test of spatial non-matching-to-sample (SNMTS), and chickadees are more resistant to interference in this paradigm. Hippocampal lesions attenuate performance in SNMTS and increase interference. In tests of continuous spatial alternation (CSA), juncos perform better than chickadees. CSA performance also declines following hippocampal lesions. By itself, sensitivity of a given task to hippocampal damage does not predict the direction of memory differences between storing and nonstoring species.

	Title	Tufted capuchins (Cebus apella) adapt their communicative behaviour to human’s attentional states			Type	Journal Article
	Year	2015	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	18	Issue	3	Pages	747-755
	Keywords	Gestural communication; Intentionality; Non-human primates; Social cognition; Attention; Pointing
	Abstract	Animal communication has become a widely studied field of research, especially because of the associated debates on the origin of human language. Due to their phylogenetic proximity with humans, non-human primates represent a suitable model to investigate the precursors of language. This study focuses on the perception of the attentional states of others, an important prerequisite to intentional communication. We investigated whether capuchins (Cebus apella) produce a learnt pointing gesture towards a hidden and unreachable food reward as a function of the attentional status of the human experimenter. For that purpose, we tested five subjects that we first trained to indicate by a pointing gesture towards the human partner the position of a reward hidden by an assistant. Then, capuchins were tested in two experimental conditions randomly ordered. In the first condition—motivation trial—the experimenter was attentive to the subject gestures and rewarded him immediately when it pointed towards the baited cylinder. During the second condition—test trial—the experimenter adopted one of the following attention states and the subject was rewarded after 10 s has elapsed, regardless of the subject’s behaviour. Five attentional states were tested: (1) experimenter absent, (2) experimenter back to the monkey, (3) experimenter’s head away, (4) experimenter watching above the monkey, and (5) experimenter watching the monkey face. Our results reveal a variation in our subjects’ communicative behaviours with a discrimination of the different postural clues (body and head orientation) available in our experimental conditions. This study suggests that capuchins can flexibly use a communicative gesture to adapt to the attentional state of their partner and provides evidence that acquired communicative gestures of monkeys might be used intentionally.

	Title	A horse race of a different color: Stroop interference patterns with transformed words			Type	Journal Article
	Year	1984	Publication	Journal of Experimental Psychology. Human Perception and Performance	Abbreviated Journal	J Exp Psychol Hum Percept Perform
	Volume	10	Issue	5	Pages	622-639
	Keywords	Attention; Color Perception; Discrimination Learning; Humans; Orientation; Reaction Time; Reading; *Semantics
	Abstract	Four experiments investigated Stroop interference using geometrically transformed words. Over experiments, reading was made increasingly difficult by manipulating orientation uncertainty and the number of noncolor words. As a consequence, time to read color words aloud increased dramatically. Yet, even when reading a color word was considerably slower than naming the color of ink in which the word was printed, Stroop interference persisted virtually unaltered. This result is incompatible with the simple horse race model widely used to explain color-word interference. When reading became extremely slow, a reversed Stroop effect--interference in reading the word due to an incongruent ink color--appeared for one transformation together with the standard Stroop interference. Whether or not the concept of automaticity is invoked, relative speed of processing the word versus the color does not provide an adequate overall explanation of the Stroop phenomenon.

	Title	Survival with an asymmetrical brain: advantages and disadvantages of cerebral lateralization			Type	Journal Article
	Year	2005	Publication	The Behavioral and Brain Sciences	Abbreviated Journal	Behav Brain Sci
	Volume	28	Issue	4	Pages	575-89; discussion 589-633
	Keywords	Animals; Attention/physiology; Behavior/physiology; Behavior, Animal/physiology; Dominance, Cerebral/physiology; *Evolution; Humans; Models, Biological; Visual Perception/physiology
	Abstract	Recent evidence in natural and semi-natural settings has revealed a variety of left-right perceptual asymmetries among vertebrates. These include preferential use of the left or right visual hemifield during activities such as searching for food, agonistic responses, or escape from predators in animals as different as fish, amphibians, reptiles, birds, and mammals. There are obvious disadvantages in showing such directional asymmetries because relevant stimuli may be located to the animal's left or right at random; there is no a priori association between the meaning of a stimulus (e.g., its being a predator or a food item) and its being located to the animal's left or right. Moreover, other organisms (e.g., predators) could exploit the predictability of behavior that arises from population-level lateral biases. It might be argued that lateralization of function enhances cognitive capacity and efficiency of the brain, thus counteracting the ecological disadvantages of lateral biases in behavior. However, such an increase in brain efficiency could be obtained by each individual being lateralized without any need to align the direction of the asymmetry in the majority of the individuals of the population. Here we argue that the alignment of the direction of behavioral asymmetries at the population level arises as an “evolutionarily stable strategy” under “social” pressures occurring when individually asymmetrical organisms must coordinate their behavior with the behavior of other asymmetrical organisms of the same or different species.

	Title	A horse of a different colour: do patients with semantic dementia recognise different versions of the same object as the same?			Type	Journal Article
	Year	2006	Publication	Neuropsychologia	Abbreviated Journal	Neuropsychologia
	Volume	44	Issue	4	Pages	566-575
	Keywords	Adult; Aged; Anomia/diagnosis/psychology; Atrophy; Attention; Color Perception; Dementia/diagnosis/psychology; Discrimination Learning; Dominance, Cerebral; Female; Humans; Male; Memory, Short-Term; Middle Aged; Neuropsychological Tests; Orientation; *Pattern Recognition, Visual; Reference Values; Retention (Psychology); Semantics; Size Perception; Temporal Lobe/pathology
	Abstract	Ten patients with semantic dementia resulting from bilateral anterior temporal lobe atrophy, and 10 matched controls, were tested on an object recognition task in which they were invited to choose (from a four-item array) the picture representing “the same thing” as an object picture that they had just inspected and attempted to name. The target in the response array was never physically identical to the studied picture but differed from it – in the various conditions – in size, angle of view, colour or exemplar (e.g. a different breed of dog). In one test block for each patient, the response array was presented immediately after the studied picture was removed; in another block, a 2 min filled delay was inserted between study and test. The patients performed relatively well when the studied object and target response differed only in the size of the picture on the page, but were significantly impaired as a group in the other three type-of-change conditions, even with no delay between study and test. The five patients whose structural brain imaging revealed major right-temporal atrophy were more impaired overall, and also more affected by the 2 min delay, than the five patients with an asymmetric pattern characterised by predominant left-sided atrophy. These results are interpreted in terms of a hypothesis that successful classification of an object token as an object type is not a pre-semantic ability but rather results from interaction of perceptual and conceptual processing.

	Title	The effect of development and individual differences in pointing comprehension of dogs			Type	Journal Article
	Year	2009	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	12	Issue	3	Pages	471-479
	Keywords	Age Factors; Analysis of Variance; Animals; Association Learning; Attention; Chi-Square Distribution; Choice Behavior; Comprehension; Concept Formation; Dogs/psychology; Female; *Gestures; Humans; Male; Orientation; Statistics, Nonparametric
	Abstract	In spite of the rather different procedures actually used in comparative studies to test the ability of different species to rely on the human pointing gesture, there is no debate on the high performance of dogs in such tasks. Very little is known, however, on the course through which they acquire this ability or the probable factors influencing the process. Important developmental questions have remained unsolved and also some methodological concerns should be addressed before we can convincingly argue for one interpretation or another. In this study we tested 180 dogs of different age (from 2 months to adults) to investigate their performance in the human distal momentary pointing gesture. The results, analyzed at both the group and the individual levels, showed no difference in the performance according to age, indicating that in dogs the comprehension of the human pointing may require only very limited and rapid early learning to fully develop. Interestingly, neither the keeping conditions nor the time spent in active interaction with the owner, and not even some special (agility) training for using human visual cues, had significant effect on the success and explained individual differences. The performance of the dogs was rather stable over time: during the 20 trials within a session and even when subsamples of different age were repeatedly tested. Considering that in spite of the general success at the group level, more than half of the dogs were not successful at the individual level, we revealed alternative “decision-making rules” other than following the pointing gesture of the experimenter.
