A Migratory Sparrow Has Personality In Winter That Is Independent Of Other Traits, Theadora A. Block, Rachel Star, Daizaburo Shizuka, Alexis S. Chaine, Bruce E. Lyon Aug 2021

A Migratory Sparrow Has Personality In Winter That Is Independent Of Other Traits, Theadora A. Block, Rachel Star, Daizaburo Shizuka, Alexis S. Chaine, Bruce E. Lyon

Papers in Behavior in Biological Sciences

Small birds in winter face trade-offs between predation risk and foraging, and alternate life-history strategies may arise from these trade-offs. Animal personality shows similarities with alternative life-history strategies, and using a life-history context to understand personality can provide valuable insights. Golden-crowned sparrows, Zonotrichia atricapilla, a small migratory bird, have a complex winter social system with high site-fidelity, long-term social associations between individuals and competition mediated by badges of status. We asked whether golden-crowned sparrows show personalities during winter, whether these personalities were consistent over 3 years and whether they correlated with social and morphological traits. We found that …


Social Partners And Temperature Jointly Affect Morning Foraging Activity Of Small Birds In Winter, Anastasia E. Madsen, Laura N. Vander Meiden, Daizaburo Shizuka May 2021

Social Partners And Temperature Jointly Affect Morning Foraging Activity Of Small Birds In Winter, Anastasia E. Madsen, Laura N. Vander Meiden, Daizaburo Shizuka

Papers in Behavior in Biological Sciences

Daily foraging activity of small wintering birds is classically thought to be driven by the need to gather enough energy reserves to survive each night. A separate line of research has shown that sociality is a major driver in winter foraging activities in many species. Here, we used wintering birds as a study system to move toward an integrative understanding of the influence of energy requirements and sociality on foraging ecology. We used RFID-enabled feeders in Lincoln, Nebraska, USA in January–March 2019 to measure foraging activity in two species (downy woodpeckers, Dryobates pubescens, and white-breasted nuthatches, Sitta carolinensis). …


Neural Circuitry For Target Selection And Action Selection In Animal Behavior, Daizaburo Shizuka, Eileen Hebets, Kim L. Hoke Jan 2017

Neural Circuitry For Target Selection And Action Selection In Animal Behavior, Daizaburo Shizuka, Eileen Hebets, Kim L. Hoke

Papers in Behavior in Biological Sciences

Animal behaviorists have long strived for a comprehensive understanding of the proximate and ultimate causes of complex behavior, and we propose that recent advances in neurobiology can help reshape or clarify this behavior-oriented understanding. We begin with an overview of current views of neural circuit mechanisms that mediate target selection and action selection. In target selection, different stimuli compete for priority in sensory-motor process- ing. Action selection is the process by which multiple possible motor actions compete for priority in a manner which balances the needs of the animal with opportunities or threats in the environment. We next discuss spatial …


Range-Wide Patterns Of Geographic Variation In Songs Of Golden-Crowned Sparrows (Zonotrichia Atricapilla), Daizaburo Shizuka, Glen Chilton, M Ross Lein Jun 2016

Range-Wide Patterns Of Geographic Variation In Songs Of Golden-Crowned Sparrows (Zonotrichia Atricapilla), Daizaburo Shizuka, Glen Chilton, M Ross Lein

Papers in Behavior in Biological Sciences

Discrete geographic variation, or dialects, in songs of songbirds arise as a consequence of complex interactions between ecology and song learning. Four of the five species of Zonotrichia sparrows, including the model species White-crowned Sparrow (Z. leucophrys), have been studied with respect to the causes and consequences of geographic variation in song. Within White-crowned Sparrows, subspecies that migrate farther have larger range size of dialects. Here, we assessed geographic patterns of song variation in the fifth species of this genus, the Golden-crowned Sparrow (Z. atricapilla). We analyzed field-recorded songs from 2 sampling periods (1996–1998 and 2006–2013) covering most of its …


Multimodal Signalling In The North American Barn Swallow: A Phenotype Network Approach, Daizaburo Shizuka, Matthew R. Wilkins, Maxwell Joseph, Joanna K. Hubbard, Rebecca Safran Jan 2015

Multimodal Signalling In The North American Barn Swallow: A Phenotype Network Approach, Daizaburo Shizuka, Matthew R. Wilkins, Maxwell Joseph, Joanna K. Hubbard, Rebecca Safran

Papers in Behavior in Biological Sciences

Complex signals, involving multiple components within and across modal- ities, are common in animal communication. However, decomposing complex signals into traits and their interactions remains a fundamental challenge for studies of phenotype evolution. We apply a novel phenotype network approach for studying complex signal evolution in the North American barn swallow (Hirundo rustica erythrogaster). We integrate model testing with correlation-based phenotype networks to infer the contributions of female mate choice and male–male competition to the evolution of barn swallow communication. Overall, the best predictors of mate choice were distinct from those for competition, while moderate functional overlap suggests …


The Dynamics Of Animal Social Networks: Analytical, Conceptual, And Theoretical Advances, Noa Pinter-Wollman, Elizabeth A. Hobson, Jennifer E. Smith, Andrew Edelman, Daizaburo Shizuka, Shermin De Silva, James Waters, Steven D. Prager, Takao Sasaki, George Wittemyer, Jennifer Fewell, David B. Mcdonald Mar 2014

The Dynamics Of Animal Social Networks: Analytical, Conceptual, And Theoretical Advances, Noa Pinter-Wollman, Elizabeth A. Hobson, Jennifer E. Smith, Andrew Edelman, Daizaburo Shizuka, Shermin De Silva, James Waters, Steven D. Prager, Takao Sasaki, George Wittemyer, Jennifer Fewell, David B. Mcdonald

Papers in Behavior in Biological Sciences

Social network analysis provides a broad and complex perspective on animal sociality that is widely applicable to almost any species. Recent applications demonstrate the utility of network analysis for advancing our understanding of the dynamics, selection pressures, development, and evolution of complex social systems. However, most studies of animal social networks rely primarily on a descriptive approach. To propel the field of animal social networks beyond exploratory analyses and to facilitate the integration of quantitative methods that allow for the testing of ecologically and evolutionarily relevant hypotheses, we review methodological and conceptual advances in network science, which are underutilized in …


Landmark Use By Clark’S Nutcrackers (Nucifraga Columbiana): Influence Of Disorientation And Cue Rotation On Distance And Direction Estimates, Debbie M. Kelly, Alan Kamil, Ken Cheng Jan 2010

Landmark Use By Clark’S Nutcrackers (Nucifraga Columbiana): Influence Of Disorientation And Cue Rotation On Distance And Direction Estimates, Debbie M. Kelly, Alan Kamil, Ken Cheng

Papers in Behavior in Biological Sciences

Many species have been shown to encode multiple sources of information to orient. To examine what kinds of information animals use to locate a goal we manipulated cue rotation, cue availability, and inertial orientation when the food-storing Clark’s nutcracker (Nucifraga columbiana) was searching for a hidden goal in a circular arena. Three groups of birds were used, each with a different goal–landmark distance. As the distance between the goal and the landmark increased, nutcrackers were less accurate in finding the correct direction to the goal than they were at estimating the distance (Experiment 1). To further examine what …


Use Of A Geometric Rule Or Absolute Vectors: Landmark Use By Clark’S Nutcrackers (Nucifraga Columbiana), Debbie M. Kelly, Sarah Kippenbrock, Jennifer J. Templeton, Alan Kamil Mar 2008

Use Of A Geometric Rule Or Absolute Vectors: Landmark Use By Clark’S Nutcrackers (Nucifraga Columbiana), Debbie M. Kelly, Sarah Kippenbrock, Jennifer J. Templeton, Alan Kamil

Papers in Behavior in Biological Sciences

Clark’s nutcrackers (Nucifraga columbiana) were trained to search for a hidden goal located in the center of a four-landmark array. Upon completion of training, the nutcrackers were presented with tests that expanded the landmark array in the east-west direction, north-south direction and in both directions simultaneously. Although the birds learned to search accurately at the center of the landmark array during training, this search pattern did not transfer to the expansion tests. The nutcrackers searched at locations defined by absolute distance and/or direction relationships with landmarks in the training array. These results contrast with those from experiments with …


Memory In Food Caching Animals, Alan C. Kamil, Kristy L. Gould Jan 2008

Memory In Food Caching Animals, Alan C. Kamil, Kristy L. Gould

Papers in Behavior in Biological Sciences

One of the more interesting developments in the study of learning and cognition over the past 25 years has been the realization that learning and memory play an important role in the natural world of many animals. As this realization led to research into animal cognition in natural settings, it became clear that such research can make important contributions to our understanding of animal and human cognition. In this chapter, we review one of the areas of research that originally stimulated interest in the role of memory in the field, the ability of many food-storing animals to remember where they …


Serial Reversal Learning And The Evolution Of Behavioral Flexibility In Three Species Of North American Corvids (Gymnorhinus Cyanocephalus, Nucifraga Columbiana, Aphelocoma Californica), Alan B. Bond, Alan Kamil, Russell P. Balda Jan 2007

Serial Reversal Learning And The Evolution Of Behavioral Flexibility In Three Species Of North American Corvids (Gymnorhinus Cyanocephalus, Nucifraga Columbiana, Aphelocoma Californica), Alan B. Bond, Alan Kamil, Russell P. Balda

Papers in Behavior in Biological Sciences

In serial reversal learning, subjects learn to respond differentially to 2 stimuli. When the task is fully acquired, reward contingencies are reversed, requiring the subject to relearn the altered associations. This alternation of acquisition and reversal can be repeated many times, and the ability of a species to adapt to this regimen has been considered as an indication of behavioral flexibility. Serial reversal learning of 2-choice discriminations was contrasted in 3 related species of North American corvids: pinyon jays (Gymnorhinus cyanocephalus), which are highly social; Clark’s nutcrackers (Nucifraga columbiana), which are relatively solitary but specialized for …


Pigeons And People Select Efficient Routes When Solving A One-Way “Traveling Salesperson” Task, Brett M. Gibson, Edward A. Wasserman, Alan C. Kamil Jan 2007

Pigeons And People Select Efficient Routes When Solving A One-Way “Traveling Salesperson” Task, Brett M. Gibson, Edward A. Wasserman, Alan C. Kamil

Papers in Behavior in Biological Sciences

The authors presented people (Experiment 1) and pigeons (Experiments 2 and 3) with a large number of 1-way traveling salesperson problems that consisted of 3, 4, and 5 identical stimuli (nodes) on a computer monitor. The sequence of nodes that each traveler selected was recorded, and the distance of the route was subsequently determined. The routes the pigeons and people selected were reliably more efficient than those used by a Monte Carlo model given the same problems. The pigeons’ routes were significantly less efficient than a nearest neighbor model of performance, however. In Experiment 3, pigeons were required to select …


Does Seed-Caching Experience Affect Spatial Memory Performance By Pinyon Jays?, B. Lucas Stafford, Russell P. Balda, Alan Kamil Dec 2006

Does Seed-Caching Experience Affect Spatial Memory Performance By Pinyon Jays?, B. Lucas Stafford, Russell P. Balda, Alan Kamil

Papers in Behavior in Biological Sciences

Food-storing birds use spatial memory to find previously cached food items. Throughout winter, pinyon jays (Gymnorhinus cyanocephalus) rely heavily on cached pinyon pine (Pinus edulis) seeds. Because of a recent severe drought, pinyon pine trees had not produced a significant seed crop for several years. Therefore, 1- and 2-year-old birds never had the opportunity to cache and recover seeds and birds 4 or more years of age had not recovered seeds in 3 years. This study examined whether natural but extreme variability in experience might result in differences in abstract spatial memory ability during a non-cache …


Linking Life Zones, Life History Traits, Ecology, And Spatial Cognition In Four Allopatric Southwestern Seed Caching Corvids, Russell P. Balda, Alan Kamil Nov 2006

Linking Life Zones, Life History Traits, Ecology, And Spatial Cognition In Four Allopatric Southwestern Seed Caching Corvids, Russell P. Balda, Alan Kamil

Papers in Behavior in Biological Sciences

This report will review the similarities and differences of four species of pine seed caching members of the avian family Corvidae that live on the slopes and base of the San Francisco Peaks in north-central Arizona. The four species include the Clark’s nutcracker (Nucifraga columbiana), pinyon jay (Gymnorhinus cyanocephalus), western scrub-jay (Aphelocoma californica), and Mexican jay (A. ultramarina). These corvids demonstrate a specialization gradient for the harvesting, transporting, caching and recovering of buried pine seeds. This gradient is reflected in their dependence on cached pine seeds for winter and early spring survival …


Spatial Heterogeneity, Predator Cognition, And The Evolution Of Color Polymorphism In Virtual Prey, Alan B. Bond, Alan Kamil Feb 2006

Spatial Heterogeneity, Predator Cognition, And The Evolution Of Color Polymorphism In Virtual Prey, Alan B. Bond, Alan Kamil

Papers in Behavior in Biological Sciences

Cryptically colored prey species are often polymorphic, occurring in multiple distinctive pattern variants. Visual predators promote such phenotypic variation through apostatic selection, in which they attack more abundant prey types disproportionately often. In heterogeneous environments, disruptive selection to match the coloration of disparate habitat patches could also produce polymorphism, but how apostatic and disruptive selection interact in these circumstances is unknown. Here we report the first controlled selection experiment on the evolution of prey coloration on heterogeneous backgrounds, in which blue jays (Cyanocitta cristata) searched for digital moths on mixtures of dark and light patches at three different …


Social Play In Kakapo (Strigops Habroptilus) With Comparisons To Kea (Nestor Notabilis) And Kaka (Nestor Meridionalis), Judy Diamond, Daryl Eason, Clio Reid, Alan B. Bond Jan 2006

Social Play In Kakapo (Strigops Habroptilus) With Comparisons To Kea (Nestor Notabilis) And Kaka (Nestor Meridionalis), Judy Diamond, Daryl Eason, Clio Reid, Alan B. Bond

Papers in Behavior in Biological Sciences

The play behavior of the critically endangered kakapo (Strigops habroptilus; Aves: Psittaciformes: Psittacidae) is here compared to that of its closest relatives, the kea (Nestor notabilis) and the kaka (Nestor meridionalis). Contrasting kakapos, which are relatively solitary, with the more social Nestor parrots provides an attractive test of the relative contributions of phylogeny and sociality to the evolution of play. Overlapping cluster analysis of play sequences using a hypergeometric similarity metric indicated that kakapo play is generally less complex, lacking the intensity, duration, structure, and reciprocity of play in the Nestor parrots. Kakapos have …


Interference Effects In The Memory For Serially Presented Locations In Clark’S Nutcrackers, Nucifraga Columbiana, Jody L. Lewis, Alan C. Kamil Jan 2006

Interference Effects In The Memory For Serially Presented Locations In Clark’S Nutcrackers, Nucifraga Columbiana, Jody L. Lewis, Alan C. Kamil

Papers in Behavior in Biological Sciences

The authors tested the spatial memory of serially presented locations in Clark’s nutcrackers (Nucifraga columbiana). Birds were serially presented with locations in an open room. The authors buried a seed in a sand-filled cup at each location and then tested nutcrackers for their memory for each location in the list by using the cluster method. For each item in the list, the authors opened a cluster of 6 holes. Accuracy was measured by how many tries were required for the bird to find the correct location within each cluster. In Experiments 1 and 2, the authors presented 2 …


Selective Attention, Priming, And Foraging Behavior, Alan Kamil, Alan B. Bond Jan 2006

Selective Attention, Priming, And Foraging Behavior, Alan Kamil, Alan B. Bond

Papers in Behavior in Biological Sciences

Animals selectively filter and transform their sensory input, increasing the accuracy with which some stimuli are detected and effectively ignoring others. This filtering process, collectively referred to as “selective attention,” takes place at a variety of different levels in the nervous system. It was described in considerable detail by William James over a century ago (James, 1890/1950) and has been a principal focus of research in cognitive psychology for nearly 50 years (Parasuraman & Davies, 1984; Pashler, 1998; Richards, 1998). Investigations of selective attention have also been central to the study of animal cognition, where the process of attention has …


The Fine-Grained Spatial Abilities Of Three Seed-Caching Corvids, Brett M. Gibson, Alan Kamil Feb 2005

The Fine-Grained Spatial Abilities Of Three Seed-Caching Corvids, Brett M. Gibson, Alan Kamil

Papers in Behavior in Biological Sciences

We used a psychophysical method to examine the ability of three corvid species to discern fine-grained spatial information. Nutcrackers, pinyon jays, and scrub-jays were required to discriminate the distance between two landmarks on a computer screen in an operant chamber. All three species were able to discriminate between arrays that differed by 20 mm; the discrimination gradients for scrub-jays and pinyon jays were sharper than those for nutcrackers, however. The results suggest that differences in spatial memory among these species are not related to differences in fine-grained perception.


Geographic And Ontogenetic Variation In The Contact Calls Of The Kea, Alan B. Bond, Judy Diamond Jan 2005

Geographic And Ontogenetic Variation In The Contact Calls Of The Kea, Alan B. Bond, Judy Diamond

Papers in Behavior in Biological Sciences

Regional and ontogenetic variation in the contact calls of the kea (Nestor notabilis), an omnivorous and socially complex New Zealand parrot, were examined throughout the range of the species. We recorded samples of kee-ah contact calls from sixteen resident adults and eleven juveniles and demonstrated significant differences between age classes in the acoustic form of the vocalization. Canonical correlation analysis revealed a gradient in the form of the kee-ah call in both adults and juveniles along and across the escarpment of the Southern Alps, the primary longitudinal mountain range on the South Island of New Zealand. Although the …


Pinyon Jays Use Transitive Inference To Predict Social Dominance, Guillermo Paz-Y-Miño C, Alan B. Bond, Alan Kamil, Russell P. Balda Aug 2004

Pinyon Jays Use Transitive Inference To Predict Social Dominance, Guillermo Paz-Y-Miño C, Alan B. Bond, Alan Kamil, Russell P. Balda

Papers in Behavior in Biological Sciences

Living in large, stable social groups is often considered to favor the evolution of enhanced cognitive abilities, such as recognizing group members, tracking their social status and inferring relationships among them. An individual’s place in the social order can be learned through direct interactions with others, but conflicts can be time-consuming and even injurious. Because the number of possible pairwise interactions increases rapidly with group size, members of large social groups will benefit if they can make judgments about relationships on the basis of indirect evidence. Transitive reasoning should therefore be particularly important for social individuals, allowing assessment of relationships …


Sociality And The Evolution Of Intelligence, Alan Kamil Jan 2004

Sociality And The Evolution Of Intelligence, Alan Kamil

Papers in Behavior in Biological Sciences

Two recently published studies provide important new data relevant to the evolution of human intelligence. Both studies of social behavior in baboons, Bergman et al. demonstrated that baboons use two criteria simultaneously to classify other troop members, and Silk et al. showed that highly social female baboons have higher reproductive success than less social females. Taken together, these studies provide strong evidence for the importance of social context in cognitive evolution.


The Geometry Of Foraging Patterns: Components Of Thoroughness In Random Searching, Alan B. Bond Jan 2004

The Geometry Of Foraging Patterns: Components Of Thoroughness In Random Searching, Alan B. Bond

Papers in Behavior in Biological Sciences

A Monte Carlo simulation of the movements of a randomly-searching predator was used to develop a novel geometrical measure, the "thoroughness" of the search, and to investigate the effects of meander, turn asymmetry, and path length. Thoroughness varied directly with the meander and the square of the asymmetry measure and remained relatively invariant with path length. The regularity of its relationship to the generating parameters of the search and the ease with which it may be estimated from field data recommend thoroughness for use in characterizing empirical search patterns and in testing for the occurrence of systematic searching.


Clark’S Nutcrackers (Nucifraga Columbiana) And The Effects Of Goal-Landmark Distance On Overshadowing, Aleida J. Goodyear, Alan Kamil Jan 2004

Clark’S Nutcrackers (Nucifraga Columbiana) And The Effects Of Goal-Landmark Distance On Overshadowing, Aleida J. Goodyear, Alan Kamil

Papers in Behavior in Biological Sciences

Three groups of Clark’s nutcrackers (Nucifraga columbiana) were trained to find a goal location defined by an array of 4 landmarks that varied in goal–landmark distance. The arrays for each group differed in the distance of the closest landmark and contained goal–landmark distances that were common across groups, allowing for the examination of the effects of both relative and absolute goal–landmark distance on encoding of a landmark array. All 3 groups readily learned the task and were subsequently tested in probe tests with only single landmarks from the array available. Search error in tests with single landmarks was …


Social Play In Kaka (Nestor Meridionalis) With Comparisons To Kea (Nestor Notabilis), Judy Diamond, Alan B. Bond Jan 2004

Social Play In Kaka (Nestor Meridionalis) With Comparisons To Kea (Nestor Notabilis), Judy Diamond, Alan B. Bond

Papers in Behavior in Biological Sciences

Social play in the kaka (Nestor meridionalis), a New Zealand parrot, is described and contrasted with that of its closest relative, the kea (Nestor notabilis), in one of the first comparative studies of social play in closely related birds. Most play action patterns were clearly homologous in these two species, though some contrasts in the form of specific play behaviors, such as kicking or biting, could be attributed to morphological differences. Social play in kakas is briefer, more predictable, and less sequentially diverse than that shown by keas. Kaka play also appears to be restricted to …


Social Complexity And Transitive Inference In Corvids, Alan B. Bond, Alan Kamil, Russell P. Balda Jan 2003

Social Complexity And Transitive Inference In Corvids, Alan B. Bond, Alan Kamil, Russell P. Balda

Papers in Behavior in Biological Sciences

The social complexity hypothesis asserts that animals living in large social groups should display enhanced cognitive abilities along predictable dimensions. To test this concept, we compared highly social pinyon jays, Gymnorhinus cyanocephalus, with relatively nonsocial western scrub-jays, Aphelocoma californica, on two complex cognitive tasks relevant to the ability to track and assess social relationships. Pinyon jays learned to track multiple dyadic relationships more rapidly and more accurately than scrub-jays and appeared to display a more robust and accurate mechanism of transitive inference. These results provide a clear demonstration of the association between social complexity and cognition in animals.


Searching By Rules: Pigeons’ (Columba Livia) Landmark-Based Search According To Constant Bearing Or Constant Distance, Marcia C. Spetch, Tiana B. Rust, Alan Kamil, Juli E. Jones Jan 2003

Searching By Rules: Pigeons’ (Columba Livia) Landmark-Based Search According To Constant Bearing Or Constant Distance, Marcia C. Spetch, Tiana B. Rust, Alan Kamil, Juli E. Jones

Papers in Behavior in Biological Sciences

Pigeons (Columba livia) searched for a goal location defined by a constant relative spatial relationship to 2 landmarks. For one group, landmark-to-goal bearings remained constant while distance varied. For another group, landmark-to-goal distances remained constant while direction varied. Birds were trained with 4 interlandmark distances and then tested with 5 novel interlandmark distances. Overall error magnitude was similar across groups and was larger than previously reported for Clark’s nutcrackers (Nucifraga columbiana). During training, error magnitude increased with interlandmark distance for constant-bearing but not constant-distance birds. Both groups searched less accurately along the axis parallel to landmarks …


A Comparative Analysis Of Social Play In Birds, Judy Diamond, Alan B. Bond Jan 2003

A Comparative Analysis Of Social Play In Birds, Judy Diamond, Alan B. Bond

Papers in Behavior in Biological Sciences

Although social play is broadly distributed among mammals, it is infrequently encountered in other vertebrate taxa. It is, however, displayed in a fully realized and complex form in several groups of birds. Unambiguous accounts of social play have been recorded from thirteen species of parrots, seven species of corvids, and several hornbills and Eurasian babblers. We conducted an analysis of the avian play literature, testing for differences between avian taxa, as well as for correlations between play complexity, brain size, and age of first reproduction. Corvids were far more likely to show social object play than parrots. Corvids, parrots, and …


Visual Predators Select For Crypticity And Polymorphism In Virtual Prey, Alan B. Bond, Alan Kamil Feb 2002

Visual Predators Select For Crypticity And Polymorphism In Virtual Prey, Alan B. Bond, Alan Kamil

Papers in Behavior in Biological Sciences

Cryptically colored animals commonly occur in several distinct pattern variants. Such phenotypic diversity may be promoted by frequency-dependent predation, in which more abundant variants are attacked disproportionately often, but the hypothesis has never been explicitly tested. Here we report the first controlled experiment on the effects of visual predators on prey crypticity and phenotypic variance, in which blue jays (Cyanocitta cristata) searched for digital moths on computer monitors. Moth phenotypes evolved via a genetic algorithm in which individuals detected by the jays were much less likely to reproduce. Jays often failed to detect atypical cryptic moths, confirming frequency- …


‘Neuroecologists’ Are Not Made Of Straw, Robert R. Hampton, Susan D. Healy, Sara J. Shettleworth, Alan Kamil Jan 2002

‘Neuroecologists’ Are Not Made Of Straw, Robert R. Hampton, Susan D. Healy, Sara J. Shettleworth, Alan Kamil

Papers in Behavior in Biological Sciences

In the October issue of Trends in Cognitive Sciences, Bolhuis and Macphail criticized the functional/evolutionary approach to the neural mechanisms of learning and memory, and concluded that the approach is ‘often misleading and might provide us with the wrong answers’ [1]. Their critique touches on a number of interesting issues, and provides a useful prompt to examine the role of an adaptationist approach to the study of cognition. In their effort to stimulate discussion, however, Bolhuis and Macphail have overstated positions they attribute to ‘neuroecologists’.


Cognition As An Independent Variable: Virtual Ecology, Alan C. Kamil, Alan B. Bond Jan 2002

Cognition As An Independent Variable: Virtual Ecology, Alan C. Kamil, Alan B. Bond

Papers in Behavior in Biological Sciences

On close examination, human cultural artifacts bear the unmistakable impress of the structure of the human mind: our tools, habitations. and methods of communication have been molded to suit the strengths and limitations of the human cognitive system (Nosman 1988). It has not commonly been emphasized. however. that similar shaping processes have taken place over the course of biological evolution in response to the cognitive features of other, nonhuman species (Bonner 1980; von Frisch 1974).
Cognitive influences are particularly evident in the modifications of color patterns and behavior of prey species that take advantage of biases and constraints in the …
