	Title	Directed movement and orientation across a large natural landscape by zebras, Equus burchelli antiquorum			Type	Journal Article
	Year	2008	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	76	Issue	2	Pages	277-285
	Keywords	correlated random walk; directed movement; Equus burchelli antiquorum; Gps; movement path; orientation; spatial memory; spatial scale; zebra
	Abstract	We investigated how plains zebras moved across a large natural landscape by analysing the movement paths of nine zebra mares foraging out from spatially confined waterholes during the dry season in the Makgadikgadi Pans National Park, Botswana. Since it was essential to investigate directed movement over a range of spatial scales to determine the correct movement behaviour and strategy, we used Nams's scaling test for oriented movement. Zebras followed directed movement paths in the lower to medium spatial scales (10 m–3.7 km) and above their visual, and possibly olfactory, range. The spatial scale of directed movement suggests that zebras had a well-defined spatial awareness and cognitive ability. Seven zebras used directed movement paths, but the remaining two followed paths not significantly different to a correlated random walk (CRW). At large spatial scales (>3 km) no distinct movement pattern could be identified and paths could not be distinguished from a CRW. Foraging strategy affected the extent of directed movement: zebras with a confined dispersion of grazing patches around the central place directed their movements over a longer distance. Zebras may extend the distance at which they can direct their movement after improving their knowledge of the local environment.

	Title	Localization of tones by horses: use of binaural cues and the role of the superior olivary complex			Type	Journal Article
	Year	1986	Publication	Behavioral Neuroscience	Abbreviated Journal	Behav Neurosci
	Volume	100	Issue	1	Pages	93-103
	Keywords	Animals; Auditory Pathways/physiology; Auditory Perception/physiology; Avoidance Learning/physiology; Brain Mapping; Electroshock; Female; Horses/physiology; Male; Olivary Nucleus/anatomy & histology/physiology; Orientation/physiology; Pitch Perception/physiology; Sound Localization/physiology
	Abstract	The ability of horses to use binaural time and intensity difference cues to localize sound was assessed in free-field localization tests by using pure tones. The animals were required to discriminate the locus of a single tone pip ranging in frequency from 250 Hz to 25 kHz emitted by loudspeakers located 30 degrees to the left and right of the animals' midline (60 degrees total separation). Three animals were tested with a two-choice procedure; 2 additional animals were tested with a conditioned avoidance procedure. All 5 animals were able to localize 250 Hz, 500 Hz, and 1 kHz but were completely unable to localize 2 kHz and above. Because the frequency of ambiguity for the binaural phase cue delta phi for horses in this test was calculated to be 1.5 kHz, these results indicate that horses can use binaural time differences in the form of delta phi but are unable to use binaural intensity differences. This finding was supported by an unconditioned orientation test involving 4 additional horses, which showed that horses correctly orient to a 500-Hz tone pip but not to an 8-kHz tone pip. Analysis of the superior olivary complex, the brain stem nucleus at which binaural interactions first take place, reveals that the lateral superior olive (LSO) is relatively small in the horse and lacks the laminar arrangement of bipolar cells characteristic of the LSO of most mammals that can use binaural delta I.

	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.

	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	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	Computations on metric maps in mammals: getting oriented and choosing a multi-destination route			Type	Journal Article
	Year	1996	Publication	The Journal of Experimental Biology	Abbreviated Journal	J Exp Biol
	Volume	199	Issue	Pt 1	Pages	211-217
	Keywords	Animals; Brain/physiology; Cercopithecus aethiops; Cognition/physiology; Humans; Mammals/physiology; Movement; Orientation/physiology; Rats; Space Perception; Visual Pathways/physiology
	Abstract	The capacity to construct a cognitive map is hypothesized to rest on two foundations: (1) dead reckoning (path integration); (2) the perception of the direction and distance of terrain features relative to the animal. A map may be constructed by combining these two sources of positional information, with the result that the positions of all terrain features are represented in the coordinate framework used for dead reckoning. When animals need to become reoriented in a mapped space, results from rats and human toddlers indicate that they focus exclusively on the shape of the perceived environment, ignoring non-geometric features such as surface colors. As a result, in a rectangular space, they are misoriented half the time even when the two ends of the space differ strikingly in their appearance. In searching for a hidden object after becoming reoriented, both kinds of subjects search on the basis of the object's mapped position in the space rather than on the basis of its relationship to a goal sign (e.g. a distinctive container or nearby marker), even though they have demonstrably noted the relationship between the goal and the goal sign. When choosing a multidestination foraging route, vervet monkeys look at least three destinations ahead, even though they are only capable of keeping a maximum of six destinations in mind at once.

	Title	Dolphin pointing is linked to the attentional behavior of a receiver			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	4	Pages	231-238
	Keywords	Animal Communication; Animals; Association Learning; Attention; Dolphins/psychology; *Gestures; Humans; Imitative Behavior; Male; Orientation; Posture; Species Specificity
	Abstract	In 2001, Xitco et al. (Anim Cogn 4:115-123) described spontaneous behaviors in two bottlenose dolphins (Tursiops truncatus) that resembled pointing and gaze alternation. The dolphins' spontaneous behavior was influenced by the presence of a potential receiver, and the distance between the dolphin and the receiver. The present study adapted the technique of Call and Tomasello [(1994) J Comp Psychol 108:307-317], used with orangutans to test the effect of the receiver's orientation on pointing in these same dolphins. The dolphins directed more points and monitoring behavior at receivers whose orientation was consistent with attending to the dolphins. The results demonstrated that the dolphins' pointing and monitoring behavior, like that of apes and infants, was linked to the attentional behavior of the receiver.

	Title	Body orientation and face orientation: two factors controlling apes' behavior from humans			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	4	Pages	216-223
	Keywords	Animals; Attention; Behavior, Animal; Cognition; Concept Formation; Face; Facial Expression; Female; Fixation, Ocular; Hominidae/psychology; Humans; Male; Nonverbal Communication; Orientation; Pan paniscus/psychology; Pan troglodytes/psychology; Pongo pygmaeus/psychology; *Posture; Social Perception; Species Specificity
	Abstract	A number of animal species have evolved the cognitive ability to detect when they are being watched by other individuals. Precisely what kind of information they use to make this determination is unknown. There is particular controversy in the case of the great apes because different studies report conflicting results. In experiment 1, we presented chimpanzees, orangutans, and bonobos with a situation in which they had to request food from a human observer who was in one of various attentional states. She either stared at the ape, faced the ape with her eyes closed, sat with her back towards the ape, or left the room. In experiment 2, we systematically crossed the observer's body and face orientation so that the observer could have her body and/or face oriented either towards or away from the subject. Results indicated that apes produced more behaviors when they were being watched. They did this not only on the basis of whether they could see the experimenter as a whole, but they were sensitive to her body and face orientation separately. These results suggest that body and face orientation encode two different types of information. Whereas face orientation encodes the observer's perceptual access, body orientation encodes the observer's disposition to transfer food. In contrast to the results on body and face orientation, only two of the tested subjects responded to the state of the observer's eyes.

	Title	Chimpanzees' (Pan troglodytes) use of gaze cues in object-choice tasks: different methods yield different results			Type	Journal Article
	Year	2005	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	2	Pages	84-92
	Keywords	Animals; Attention; Choice Behavior; Cues; Eye Movements; Female; Male; Nonverbal Communication; Orientation; Pan troglodytes/psychology; Social Environment
	Abstract	To assess the influence of different procedures on chimpanzees' performance in object-choice tasks, five adult chimpanzees were tested using three experimenter-given cues to food location: gazing, glancing, and pointing. These cues were delivered to the subjects in an identical fashion but were deployed within the context of two distinct meta-procedures that have been previously employed with this species with conflicting results. In one procedure, the subjects entered the test unit and approached the experimenter (who had already established the cue) on each trial. In the other procedure, the subjects stayed in the test unit throughout a session, witnessed the hiding procedure, and waited for a delay of 10 s during which the cue was provided. The subjects scored at high levels far exceeding chance in response to the gaze cue only when they approached the experimenter for each trial. They performed at chance levels when they stayed inside the test unit throughout the session. They scored at chance levels on all other cues irrespective of the procedure. These findings imply that (a) chimpanzees can immediately exploit social gaze cues, and (b) previous conflicting findings were likely due to the different meta-procedures that were used.
