	Title	In search of king Solomon's ring: cognitive and communicative studies of Grey parrots (Psittacus erithacus)			Type	Journal Article
	Year	2002	Publication	Brain, behavior and evolution	Abbreviated Journal	Brain Behav Evol
	Volume	59	Issue	1-2	Pages	54-67
	Keywords	Animal Communication; Animals; Attention/physiology; Cognition/physiology; Cues; Form Perception/physiology; Humans; Intelligence; Learning/physiology; Male; Models, Psychological; Parrots/*physiology; Psychomotor Performance/physiology; Reward; Social Behavior
	Abstract	During the past 24 years, I have used a modeling technique (M/R procedure) to train Grey parrots to use an allospecific code (English speech) referentially; I then use the code to test their cognitive abilities. The oldest bird, Alex, labels more than 50 different objects, 7 colors, 5 shapes, quantities to 6, 3 categories (color, shape, material) and uses 'no', 'come here', wanna go X' and 'want Y' (X and Y are appropriate location or item labels). He combines labels to identify, request, comment upon or refuse more than 100 items and to alter his environment. He processes queries to judge category, relative size, quantity, presence or absence of similarity/difference in attributes, and show label comprehension. He semantically separates labeling from requesting. He thus exhibits capacities once presumed limited to humans or nonhuman primates. Studies on this and other Greys show that parrots given training that lacks some aspect of input present in M/R protocols (reference, functionality, social interaction) fail to acquire referential English speech. Examining how input affects the extent to which parrots acquire an allospecific code may elucidate mechanisms of other forms of exceptional learning: learning unlikely in the normal course of development but that can occur under certain conditions.

	Title	Social cognitive evolution in captive foxes is a correlated by-product of experimental domestication			Type	Journal Article
	Year	2005	Publication	Current biology : CB	Abbreviated Journal	Curr Biol
	Volume	15	Issue	3	Pages	226-230
	Keywords	Animals; Animals, Domestic; Cognition/physiology; Cues; Evolution; Foxes/physiology; Selection (Genetics); Social Behavior; Species Specificity
	Abstract	Dogs have an unusual ability for reading human communicative gestures (e.g., pointing) in comparison to either nonhuman primates (including chimpanzees) or wolves . Although this unusual communicative ability seems to have evolved during domestication , it is unclear whether this evolution occurred as a result of direct selection for this ability, as previously hypothesized , or as a correlated by-product of selection against fear and aggression toward humans--as is the case with a number of morphological and physiological changes associated with domestication . We show here that fox kits from an experimental population selectively bred over 45 years to approach humans fearlessly and nonaggressively (i.e., experimentally domesticated) are not only as skillful as dog puppies in using human gestures but are also more skilled than fox kits from a second, control population not bred for tame behavior (critically, neither population of foxes was ever bred or tested for their ability to use human gestures) . These results suggest that sociocognitive evolution has occurred in the experimental foxes, and possibly domestic dogs, as a correlated by-product of selection on systems mediating fear and aggression, and it is likely the observed social cognitive evolution did not require direct selection for improved social cognitive ability.

	Title	The acoustic features of vervet monkey grunts			Type	Journal Article
	Year	1984	Publication	The Journal of the Acoustical Society of America	Abbreviated Journal	J Acoust Soc Am
	Volume	75	Issue	5	Pages	1623-1628
	Keywords	Acoustics; Animals; Auditory Perception; Cercopithecus/physiology; Cercopithecus aethiops/physiology; Cues; Dominance-Subordination; Female; Male; Social Behavior; Sound Spectrography; Vocalization, Animal
	Abstract	East African vervet monkeys give short (125 ms), harsh-sounding grunts to each other in a variety of social situations: when approaching a dominant or subordinate member of their group, when moving into a new area of their range, or upon seeing another group. Although all these vocalizations sound similar to humans, field playback experiments have shown that the monkeys distinguish at least four different calls. Acoustic analysis reveals that grunts have an aperiodic F0, at roughly 240 Hz. Most grunts exhibit a spectral peak close to this irregular F0. Grunts may also contain a second, rising or falling frequency peak, between 550 and 900 Hz. The location and changes in these two frequency peaks are the cues most likely to be used by vervets when distinguishing different grunt types.

	Title	Imitation and affordance learning by pigeons (Columba livia)			Type	Journal Article
	Year	2003	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	117	Issue	4	Pages	414-419
	Keywords	Animals; Behavior, Animal; Columbidae; Cues; Imitative Behavior; *Learning; Odors; Sound
	Abstract	The bidirectional control procedure was used to determine whether pigeons (Columba livia) would imitate a demonstrator that pushed a sliding screen for food. One group of observers saw a trained demonstrator push a sliding screen door with its beak (imitation group), whereas 2 other groups watched the screen move independently (possibly learning how the environment works) with a conspecific either present (affordance learning with social facilitation) or absent (affordance learning alone). A 4th group could not see the screen being pushed (sound and odor control). Imitation was evidenced by the finding that pigeons that saw a demonstrator push the screen made a higher proportion of matching screen pushes than observers in 2 appropriate control conditions. Further, observers that watched a screen move without a demonstrator present made a significantly higher proportion of matching screen pushes than would be expected by chance. Thus, these pigeons were capable of affordance learning.

	Title	Internal sense of direction and landmark use in pigeons (Columba livia)			Type	Journal Article
	Year	2005	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	119	Issue	3	Pages	273-284
	Keywords	Animals; Columbidae; Conflict (Psychology); Cues; Discrimination Learning; Homing Behavior; Intuition; Orientation; Space Perception; Transfer (Psychology); Visual Perception
	Abstract	The relative importance of an internal sense of direction based on inertial cues and landmark piloting for small-scale navigation by White King pigeons (Columba livia) was investigated in an arena search task. Two groups of pigeons differed in whether they had access to visual cues outside the arena. In Experiment 1, pigeons were given experience with 2 different entrances and all pigeons transferred accurate searching to novel entrances. Explicit disorientation before entering did not affect accuracy. In Experiments 2-4, landmarks and inertial cues were put in conflict or tested 1 at a time. Pigeons tended to follow the landmarks in a conflict situation but could use an internal sense of direction to search when landmarks were unavailable.

	Title	Making inferences about the location of hidden food: social dog, causal ape			Type	Journal Article
	Year	2006	Publication	Journal of comparative psychology	Abbreviated Journal	J Comp Psychol
	Volume	120	Issue	1	Pages	38-47
	Keywords	Animals; Communication; Cues; Dogs; Exploratory Behavior; Feeding Behavior; Female; Food; Male; Pan paniscus; Pan troglodytes; *Visual Perception
	Abstract	Domestic dogs (Canis familiaris) and great apes from the genus Pan were tested on a series of object choice tasks. In each task, the location of hidden food was indicated for subjects by some kind of communicative, behavioral, or physical cue. On the basis of differences in the ecologies of these 2 genera, as well as on previous research, the authors hypothesized that dogs should be especially skillful in using human communicative cues such as the pointing gesture, whereas apes should be especially skillful in using physical, causal cues such as food in a cup making noise when it is shaken. The overall pattern of performance by the 2 genera strongly supported this social-dog, causal-ape hypothesis. This result is discussed in terms of apes' adaptations for complex, extractive foraging and dogs' adaptations, during the domestication process, for cooperative communication with humans.

	Title	*Domestic dogs (Canis familiaris) are sensitive to the attentional state of humans*			Type	Journal Article
	Year	2003	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	117	Issue	3	Pages	257-263
	Keywords	Animals; Appetitive Behavior; Attention; Bonding, Human-Pet; Concept Formation; Cues; Dogs/psychology; Female; Humans; Inhibition (Psychology); Male; Nonverbal Communication
	Abstract	Twelve domestic dogs (Canis familiaris) were given a series of trials in which they were forbidden to take a piece of visible food. In some trials, the human continued to look at the dog throughout the trial (control condition), whereas in others, the human (a) left the room, (b) turned her back, (c) engaged in a distracting activity, or (d) closed her eyes. Dogs behaved in clearly different ways in most of the conditions in which the human did not watch them compared with the control condition, in which she did. In particular, when the human looked at them, dogs retrieved less food, approached it in a more indirect way, and sat (as opposed to laid down) more often than in the other conditions. Results are discussed in terms of domestic dogs' social-cognitive skills and their unique evolutionary and ontogenetic histories.

	Title	*Obey or not obey? Dogs (Canis familiaris) behave differently in response to attentional states of their owners*			Type	Journal Article
	Year	2006	Publication	Journal of Comparative Psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	120	Issue	3	Pages	169-175
	Keywords	Animals; Attention; Awareness; Bonding, Human-Pet; Cooperative Behavior; Cues; Dogs/psychology; Humans; Motivation; Nonverbal Communication; Social Perception; Speech Perception; *Verbal Behavior
	Abstract	Sixteen domestic dogs (Canis familiaris) were tested in a familiar context in a series of 1-min trials on how well they obeyed after being told by their owner to lie down. Food was used in 1/3 of all trials, and during the trial the owner engaged in 1 of 5 activities. The dogs behaved differently depending on the owner's attention to them. When being watched by the owner, the dogs stayed lying down most often and/or for the longest time compared with when the owner read a book, watched TV, turned his or her back on them, or left the room. These results indicate that the dogs sensed the attentional state of their owners by judging observable behavioral cues such as eye contact and eye, head, and body orientation.

	Title	*A gray seal's (Halichoerus grypus) responses to experimenter-given pointing and directional cues*			Type	Journal Article
	Year	2003	Publication	Journal of Comparative Psychology	Abbreviated Journal	J Comp Psychol
	Volume	117	Issue	4	Pages	355-362
	Keywords	Animals; Behavior, Animal/physiology; Cognition/physiology; Conditioning, Operant/physiology; Cues; Eye Movements/physiology; Female; Seals, Earless
	Abstract	A gray seal (Halichoerus grypus) was trained to touch a target on its left or right by responding to pointing signals. The authors then tested whether the seal would be able to generalize spontaneously to altered signals. It responded correctly to center pointing and head turning, center upper body turning, and off-center pointing but not to head turning and eye movements alone. The seal also responded correctly to brief ipsilateral and contralateral points from center and lateral positions. Pointing gestures did not cause the seal to select an object placed centrally behind it. Like many animals in similar studies, this gray seal probably did not understand the referential character of these gestures but rather used signal generalization and experience from initial operant conditioning to solve these tasks.

	Title	Most directed forgetting in pigeons can be attributed to the absence of reinforcement on forget trials during training or to other procedural artifacts			Type	Journal Article
	Year	1995	Publication	Journal of the experimental analysis of behavior	Abbreviated Journal	J Exp Anal Behav
	Volume	63	Issue	2	Pages	127-137
	Keywords	Animals; Attention; Color Perception; Columbidae; Cues; Discrimination Learning; Mental Recall; Motivation; Pattern Recognition, Visual; Reinforcement Schedule; Retention (Psychology)
	Abstract	In research on directed forgetting in pigeons using delayed matching procedures, remember cues, presented in the delay interval between sample and comparisons, have been followed by comparisons (i.e., a memory test), whereas forget cues have been followed by one of a number of different sample-independent events. The source of directed forgetting in delayed matching to sample in pigeons was examined in a 2 x 2 design by independently manipulating whether or not forget-cue trials in training ended with reinforcement and whether or not forget-cue trials in training included a simultaneous discrimination (involving stimuli other than those used in the matching task). Results were consistent with the hypothesis that reinforced responding following forget cues is sufficient to eliminate performance deficits on forget-cue probe trials. Only when reinforcement was omitted on forget-cue trials in training (whether a discrimination was required or not) was there a decrement in accuracy on forget-cue probe trials. When reinforcement is present, however, the pattern of responding established during and following a forget cue in training may also play a role in the directed forgetting effect. These findings support the view that much of the evidence for directed forgetting using matching procedures may result from motivational and behavioral artifacts rather than the loss of memory.
