	Title	Hippocampal lesions impair memory for location but not color in passerine birds			Type	Journal Article
	Year	1996	Publication	Behavioral neuroscience	Abbreviated Journal	Behav Neurosci
	Volume	110	Issue	4	Pages	831-835
	Keywords	Animals; Appetitive Behavior/physiology; Birds/physiology; Brain Mapping; Color Perception/physiology; Discrimination Learning/physiology; Hippocampus/physiology; Long-Term Potentiation/physiology; Mental Recall/physiology; Orientation/*physiology; Species Specificity
	Abstract	The effects of hippocampal complex lesions on memory for location and color were assessed in black-capped chickadees (Parus atricapillus) and dark-eyed juncos (Junco hyemalis) in operant tests of matching to sample. Before surgery, most birds were more accurate on tests of memory for location than on tests of memory for color. Damage to the hippocampal complex caused a decline in memory for location, whereas memory for color was not affected in the same birds. This dissociation indicates that the avian hippocampus plays an important role in spatial cognition and suggests that this brain structure may play no role in working memory generally.

	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	Mental time travel in animals: a challenging question			Type	Journal Article
	Year	2006	Publication	Behavioural processes	Abbreviated Journal	Behav. Process.
	Volume	72	Issue	2	Pages	173-183
	Keywords	Animals; Behavior, Animal; Columbidae; Concept Formation; Conditioning, Operant; Imagination; Memory; Mental Recall; Planning Techniques; Rats; Time Perception; Transfer (Psychology)
	Abstract	Humans have the ability to mentally recreate past events (using episodic memory) and imagine future events (by planning). The best evidence for such mental time travel is personal and thus subjective. For this reason, it is particularly difficult to study such behavior in animals. There is some indirect evidence, however, that animals have both episodic memory and the ability to plan for the future. When unexpectedly asked to do so, animals can report about their recent past experiences (episodic memory) and they also appear to be able to use the anticipation of a future event as the basis for a present action (planning). Thus, the ability to imagine past and future events may not be uniquely human.

	Title	Timing, memory for intervals, and memory for untimed stimuli: the role of instructional ambiguity			Type	Journal Article
	Year	2005	Publication	Behavioural processes	Abbreviated Journal	Behav. Process.
	Volume	70	Issue	3	Pages	209-222
	Keywords	Animals; Attention; Columbidae; Discrimination Learning; Memory, Short-Term; Practice (Psychology); Reinforcement Schedule; Retention (Psychology); *Time Perception
	Abstract	Theories of animal timing have had to account for findings that the memory for the duration of a timed interval appears to be dramatically shorted within a short time of its termination. This finding has led to the subjective shortening hypothesis and it has been proposed to account for the poor memory that animals appear to have for the initial portion of a timed interval when a gap is inserted in the to-be-timed signal. It has also been proposed to account for the poor memory for a relatively long interval that has been discriminated from a shorter interval. I suggest here a simpler account in which ambiguity between the gap or retention interval and the intertrial interval results in resetting the clock, rather than forgetting the interval. The ambiguity hypothesis, together with a signal salience mechanism that determines how quickly the clock is reset at the start of the intertrial interval can account for the results of the reported timing experiments that have used the peak procedure. Furthermore, instructional ambiguity rather than memory loss may account for the results of many animal memory experiments that do not involve memory for time.

	Title	Evolution of hemispheric specialization: advantages and disadvantages			Type	Journal Article
	Year	2000	Publication	Brain and Language	Abbreviated Journal	Brain Lang
	Volume	73	Issue	2	Pages	236-253
	Keywords	Aggression/psychology; Animals; Behavior, Animal/physiology; Brain/physiology; Chickens/physiology; Evolution; Feeding Behavior/physiology; Functional Laterality/*physiology; Visual Fields/physiology; Visual Perception/physiology
	Abstract	Lateralization of the brain appeared early in evolution and many of its features appear to have been retained, possibly even in humans. We now have a considerable amount of information on the different forms of lateralization in a number of species, and the commonalities of these are discussed, but there has been relatively little investigation of the advantages of being lateralized. This article reports new findings on the differences between lateralized and nonlateralized chicks. The lateralized chicks were exposed to light for 24 h on day 19 of incubation, a treatment known to lead to lateralization of a number of visually guided responses, and the nonlateralized chicks were incubated in the dark. When they were feeding, the lateralized chicks were found to detect a stimulus resembling a raptor with shorter latency than nonlateralized chicks. This difference was not a nonspecific effect caused by the light-exposed chicks being more distressed by the stimulus. Instead, it appears to be a genuine advantage conferred by having a lateralized brain. It is suggested that having a lateralized brain allows dual attention to the tasks of feeding (right eye and left hemisphere) and vigilance for predators (left eye and right hemisphere). Nonlateralized chicks appear to perform these dual tasks less efficiently than lateralized ones. Reference is made to other species in discussing these results.

	Title	Lateralization of auditory language functions: a dynamic dual pathway model			Type	Journal Article
	Year	2004	Publication	Brain and Language	Abbreviated Journal	Brain Lang
	Volume	89	Issue	2	Pages	267-276
	Keywords	Auditory Pathways/physiology; Brain Mapping; Comprehension/physiology; Dominance, Cerebral/physiology; Frontal Lobe/physiology; Humans; Nerve Net/physiology; Phonetics; Semantics; Speech Acoustics; Speech Perception/physiology; Temporal Lobe/*physiology
	Abstract	Spoken language comprehension requires the coordination of different subprocesses in time. After the initial acoustic analysis the system has to extract segmental information such as phonemes, syntactic elements and lexical-semantic elements as well as suprasegmental information such as accentuation and intonational phrases, i.e., prosody. According to the dynamic dual pathway model of auditory language comprehension syntactic and semantic information are primarily processed in a left hemispheric temporo-frontal pathway including separate circuits for syntactic and semantic information whereas sentence level prosody is processed in a right hemispheric temporo-frontal pathway. The relative lateralization of these functions occurs as a result of stimulus properties and processing demands. The observed interaction between syntactic and prosodic information during auditory sentence comprehension is attributed to dynamic interactions between the two hemispheres.

	Title	Memory and hippocampal specialization in food-storing birds: challenges for research on comparative cognition			Type	Journal Article
	Year	2003	Publication	Brain, behavior and evolution	Abbreviated Journal	Brain Behav Evol
	Volume	62	Issue	2	Pages	108-116
	Keywords	Animals; Birds/physiology; Cognition/physiology; Color Perception/physiology; Feeding Behavior/physiology; Hippocampus/physiology; Memory/*physiology; Species Specificity
	Abstract	The three-way association among food-storing behavior, spatial memory, and hippocampal enlargement in some species of birds is widely cited as an example of a new 'cognitive ecology' or 'neuroecology.' Whether this relationship is as strong as it first appears and whether it might be evidence for an adaptive specialization of memory and hippocampus in food-storers have recently been the subject of some controversy [Bolhuis and Macphail, 2001; Macphail and Bolhuis, 2001]. These critiques are based on misconceptions about the nature of adaptive specializations in cognition, misconceptions about the uniformity of results to be expected from applying the comparative method to data from a wide range of species, and a narrow view of what kinds of cognitive adaptations are theoretically interesting. New analyses of why food-storers (black-capped chickadees, Poecile Atricapilla) respond preferentially to spatial over color cues when both are relevant in a memory task show that this reflects a relative superiority of spatial memory as compared to memory for color rather than exceptional spatial attention or spatial discrimination ability. New studies of chickadees from more or less harsh winter climates also support the adaptive specialization hypothesis and suggest that within-species comparisons may be especially valuable for unraveling details of the relationships among ecology, memory, and brain in food-storing species.
