In this paper, I give an account of how our hominin ancestors evolved a conscious ability I call scenario visualization that enabled them to manufacture novel tools so as to survive and flourish in the ever-changing and complex environments
in which they lived. I first present the ideas and arguments put forward by evolutionary psychologists that the mind evolved
certain mental capacities as adaptive responses to environmental pressures. Specifically, Steven Mithen thinks that the mind
has evolved cognitive fluidity, viz., an ability to exchange information flexibly between and among mental modules. Showing the deficiency in Mithen’s view,
I then argue that the flexible exchange of information between and among modules together with scenario visualization is what explains the ability to construct the novel tools needed to survive and flourish in the environments
in which our hominin ancestors resided. Finally, I trace the development of the multi-purposed javelin, from its meager beginnings
as a stick, in order to illustrate scenario visualization in novel tool manufacturing. 相似文献

The ability to see colors is not universal in the animal kingdom. Those animals that can detect differences in the wavelengths
of the electromagnetic spectrum glean valuable sensory information about their environment. They use color vision to forage,
avoid predators, and find high-quality mates. In the past, the colors that humans could see clouded scientists’ study of animals’
color perception. Leaving that bias behind has led to new insights about how and why the color vision of animals evolved.
This paper provides a brief introduction to color vision, the genetics of color vision in humans, what colors other animals
see, and how scientists study color vision. We examine the consequences of having color vision, including speciation, loss
of olfactory capabilities, and sexual selection. 相似文献

Metaphors are cognitive instruments with the capacity to influence how humans think about the world. Guiding our representations and shaping our experiences, metaphor is of anthropological interest because it is an integral aspect of culture. This paper aims to highlight the role of metaphor in the biotechnology industry. In particular, animal metaphors provide a means of consolidating information. In a culture where time is highly restricted, metaphors enable the speedy transmission of knowledge, placing information in a familiar context or cultural model. Ethnographic findings reveal that animal metaphors contribute to a larger conceptual framework that equates biological evolution with commercial relationships. Depending on the context, metaphors both conceal and reveal different aspects of the financial world, affecting interpretations of the market. 相似文献

Computation and information processing are among the most fundamental notions in cognitive science. They are also among the
most imprecisely discussed. Many cognitive scientists take it for granted that cognition involves computation, information
processing, or both – although others disagree vehemently. Yet different cognitive scientists use ‘computation’ and ‘information
processing’ to mean different things, sometimes without realizing that they do. In addition, computation and information processing
are surrounded by several myths; first and foremost, that they are the same thing. In this paper, we address this unsatisfactory
state of affairs by presenting a general and theory-neutral account of computation and information processing. We also apply
our framework by analyzing the relations between computation and information processing on one hand and classicism, connectionism,
and computational neuroscience on the other. We defend the relevance to cognitive science of both computation, at least in a generic sense, and information processing, in three important senses of the term. Our account advances several foundational debates in cognitive science by untangling
some of their conceptual knots in a theory-neutral way. By leveling the playing field, we pave the way for the future resolution of the debates’ empirical aspects. 相似文献

Depth cues, behavioural context, and natural illumination: some potential limitations of video playback techniques 总被引:2,自引:0,他引:2
J. Zeil 《Acta ethologica》2000,3(1):39-48
By expanding on issues raised by D’Eath (1998), I address in this article three aspects of vision that are difficult to reproduce
in the video- and computer-generated images used in experiments, in which images of conspecifics or of predators are replayed
to animals. The lack of depth cues derived from binocular stereopsis, from accommodation, and from motion parallax may be one of the reasons why animals do
not respond to video displays in the same way as they do to real conspecifics or to predators. Part of the problem is the
difficulty of reproducing the closed-loop nature of natural vision in video playback experiments. Every movement an animal
makes has consequences for the pattern of stimulation on its retina and this ”optic flow” in turn carries information about
both the animal’s own movement and about the three-dimensional structure of the environment. A further critical issue is the
behavioural context that often determines what animals attend to but that may be difficult to induce or reproduce in an experimental setting.
I illustrate this point by describing some visual behaviours in fiddler crabs, in which social and spatial context define
which part of the visual field a crab attends to and which visual information is used to guide behaviour. I finally mention
some aspects of natural illumination that may influence how animals perceive an object or a scene: shadows, specular reflections, and polarisation reflections.

Attitudes towards the management of the natural environment have been described mainly as building on individuals’ images
of nature and the human–nature relationship. However, in previous qualitative research I found strong evidence that in order
to understand public views on environmental policies we also need to understand individuals’ beliefs about their fellow humans.
The present study tested the hypothesis that beliefs about human nature and preferences for certain governance approaches—such
as regulations and collective action—are related to individuals’ attitudes towards concrete management measures. Survey results
(n = 155), analysed by means of structural equation modelling, suggest that effects of beliefs about human nature are discernible,
but not significant. I could, however, identify generic preferences for particular approaches to environmental governance.
These significantly explained variation in attitudes towards environmental governance in an applied context, suggesting a
strong need for further research in this politically highly relevant field. 相似文献

To understand how our brain evolved and what it is for, we are in urgent need of knowledge about the cognitive skills of a large variety of animal species and individuals, and their relationships to rapidly disappearing social and ecological conditions. But how do we obtain this knowledge? Studying cognition in the wild is a challenge. Field researchers (and their study subjects) face many factors that can easily interfere with their variables of interest. Although field studies of cognition present unique challenges, they are still invaluable for understanding the evolutionary drivers of cognition. In this review, I discuss the advantages and urgency of field‐based studies on animal cognition and introduce a novel observational approach for field research that is guided by three questions: (a) what do animals fail to find?, (b) what do they not do?, and (c) what do they only do when certain conditions are met? My goal is to provide guidance to future field researchers examining primate cognition. 相似文献

Research on humans from birth to maturity converges with research on diverse animals to reveal foundational cognitive systems in human and animal minds. The present article focuses on two such systems of geometry. One system represents places in the navigable environment by recording the distance and direction of the navigator from surrounding, extended surfaces. The other system represents objects by detecting the shapes of small-scale forms. These two systems show common signatures across animals, suggesting that they evolved in distant ancestral species. As children master symbolic systems such as maps and language, they come productively to combine representations from the two core systems of geometry in uniquely human ways; these combinations may give rise to abstract geometric intuitions. Studies of the ontogenetic and phylogenetic sources of abstract geometry therefore are illuminating of both human and animal cognition. Research on animals brings simpler model systems and richer empirical methods to bear on the analysis of abstract concepts in human minds. In return, research on humans, relating core cognitive capacities to symbolic abilities, sheds light on the content of representations in animal minds. 相似文献

In this paper I argue that we can learn much about ‘wild justice’ and the evolutionary origins of social morality – behaving fairly – by studying social play behavior in group-living animals, and that interdisciplinary cooperation will help immensely. In our efforts to learn more about the evolution of morality we need to broaden our comparative research to include animals other than non-human primates. If one is a good Darwinian, it is premature to claim that only humans can be empathic and moral beings. By asking the question ‘What is it like to be another animal?’ we can discover rules of engagement that guide animals in their social encounters. When I study dogs, for example, I try to be a ‘dogocentrist’ and practice ‘dogomorphism.’ My major arguments center on the following ‘big’ questions: Can animals be moral beings or do they merely act as if they are? What are the evolutionary roots of cooperation, fairness, trust, forgiveness, and morality? What do animals do when they engage in social play? How do animals negotiate agreements to cooperate, to forgive, to behave fairly, to develop trust? Can animals forgive? Why cooperate and play fairly? Why did play evolve as it has? Does ‘being fair’ mean being more fit – do individual variations in play influence an individual's reproductive fitness, are more virtuous individuals more fit than less virtuous individuals? What is the taxonomic distribution of cognitive skills and emotional capacities necessary for individuals to be able to behave fairly, to empathize, to behave morally? Can we use information about moral behavior in animals to help us understand ourselves? I conclude that there is strong selection for cooperative fair play in which individuals establish and maintain a social contract to play because there are mutual benefits when individuals adopt this strategy and group stability may be also be fostered. Numerous mechanisms have evolved to facilitate the initiation and maintenance of social play to keep others engaged, so that agreeing to play fairly and the resulting benefits of doing so can be readily achieved. I also claim that the ability to make accurate predictions about what an individual is likely to do in a given social situation is a useful litmus test for explaining what might be happening in an individual's brain during social encounters, and that intentional or representational explanations are often important for making these predictions. 相似文献

In the last 10 years, several authors including Griffiths and Matthen have employed classificatory principles from biology
to argue for a radical revision in the way that we individuate psychological traits. Arguing that the fundamental basis for
classification of traits in biology is that of ‘homology’ (similarity due to common descent) rather than ‘analogy’, or ‘shared
function’, and that psychological traits are a special case of biological traits, they maintain that psychological categories
should be individuated primarily by relations of homology rather than in terms of shared function. This poses a direct challenge
to the dominant philosophical view of how to define psychological categories, viz., ‘functionalism’. Although the implications
of this position extend to all psychological traits, the debate has centered around ‘emotion’ as an example of a psychological
category ripe for reinterpretation within this new framework of classification. I address arguments by Griffiths that emotions
should be divided into at least two distinct classes, basic emotions and higher cognitive emotions, and that these two classes
require radically different theories to explain them. Griffiths argues that while basic emotions in humans are homologous
to the corresponding states in other animals, higher cognitive emotions are dependent on mental capacities unique to humans,
and are therefore not homologous to basic emotions. Using the example of shame, I argue that (a) many emotions that are commonly
classified as being higher cognitive emotions actually correspond to certain basic emotions, and that (b) the “higher cognitive
forms” of these emotions are best seen as being homologous to their basic forms. 相似文献

ABSTRACTThis paper examines the relations between humans and wild animals in the lands of the Bible and ancient Near East and the way in which these cultures used various creatures and their characteristics as metaphors for dangerous enemies. It focuses on three particular periods in which the sources at our disposal document human–wild animal interactions. The first section discusses the emergence of civilization in Mesopotamia as reflected in various texts, discussing their portrait of the epoch in which human culture took shape and domesticated animals began to be clearly differentiated from wild ones. The second part looks at human–canine relations—wild dogs and their domesticated counterparts—briefly surveying how the former serve as metaphors for enemies beyond inhabited regions as evinced in the Egyptian El-Amarna archive. The third section analyzes the human–animal relations portrayed in the biblical texts, reviewing the theological principles they adopt in relation to the animal kingdom and the way in which wild animals became a metaphor for both wicked adversaries and striking physical attributes. 相似文献

Eusociality has evolved independently at least twice among the insects: among the Hymenoptera (ants and bees), and earlier
among the Isoptera (termites). Studies of swarm intelligence, and by inference, swarm cognition, have focused largely on the
bees and ants, while the termites have been relatively neglected. Yet, termites are among the world’s premier animal architects,
and this betokens a sophisticated swarm intelligence capability. In this article, I review new findings on the workings of
the mound of Macrotermes which clarify how these remarkable structures work, and how they come to be built. Swarm cognition in these termites is in
the form of “extended” cognition, whereby the swarm’s cognitive abilities arise both from interaction amongst the individual
agents within a swarm, and from the interaction of the swarm with the environment, mediated by the mound’s dynamic architecture.
The latter provides large scale “cognitive maps” which enable termite swarms to assess the functional state of their structure
and to guide repair efforts where necessary. The crucial role of the built environment in termite swarm cognition also points
to certain “swarm cognitive disorders”, where swarms can be pushed into anomalous activities by manipulating crucial structural
and functional attributes of the termite system of “extended cognition.” 相似文献

This article argues that organisms, defined by a semi-permeable membrane or skin separating organism from environment, are
(must be) semiotically alert responders to environments (both Innenwelt and Umwelt). As organisms and environments complexify over time, so, necessarily, does semiotic responsiveness, or ‘semiotic freedom’.
In complex environments, semiotic responsiveness necessitates increasing plasticity of discernment, or discrimination. Such
judgements, in other words, involve interpretations. The latter, in effect, consist of translations of a range of sign relations
which, like metaphor, are based on transfers (carryings over) of meanings or expressions from one semiotic ‘site’ to another.
The article argues that what humans describe as ‘metaphor’ (and believe is something which only pertains to human speech and
mind and, in essence, is ‘not real’) is, in fact, fundamental to all semiotic and biosemiotic sign processes in all living
things. The article first argues that metaphor and mind are immanent in all life, and are evolutionary, and, thus, that animals
certainly do have minds. Following Heidegger and then Agamben, the article continues by asking about the place of animal mind
in humans, and concludes that, as a kind of ‘night science’, ‘humananimal’ mind is central to the semiotics of Peircean abduction. 相似文献

As a reflection on recent debates on the value of wild animals we examine the question of the intrinsic value of wild animals
in both natural and man-made surroundings. We examine the concepts being wild and domesticated. In our approach we consider
animals as dependent on their environment, whether it is a human or a natural environment. Stressing this dependence we argue
that a distinction can be made between three different interpretations of a wild animal’s intrinsic value: a species-specific,
a naturalistic, and an individualistic interpretation. According to the species-specific approach, the animal is primarily
considered as a member of its species; according to the naturalistic interpretation, the animal is seen as dependent on the
natural environment; and according to the individualistic approach, the animal is seen in terms of its relationship to humans.
In our opinion, the species-specific interpretation, which is the current dominant view, should be supplemented—but not replaced
by—naturalistic and individualistic interpretations, which focus attention on the relationship of the animal to the natural
and human environments, respectively. Which of these three interpretations is the most suitable in a given case depends on
the circumstances and the opportunity for the animal to grow and develop according to its nature and capabilities. 相似文献

The strong continuity thesis postulates that the properties of mind are an enriched version of the properties of life, and thus that life and mind differ
in degree and not kind. A philosophical problem for this view is the ostensive discontinuity between humans and other animals in virtue of our use of symbols—particularly the presumption that the symbolic
nature of human cognition bears no relation to the basic properties of life. In this paper, we make the case that a genuine
account of strong continuity requires the identification of some sort of correlate of symbol-use in basic life properties.
Our strategy is three-fold: 1) we argue that examples of proto-symbolism in simple living systems would be consistent with
an evolutionary trajectory that ultimately produced symbolic cognition in humans; 2) we introduce Gordon Tomkins’ biological
notion of ‘symbol’ as something that represents to the organism a feature of its environment that is significant to its survival;
and 3) we employ this biological understanding of symbol-use to suggest that the symbolic nature of human cognition can be
understood as an enriched version of the basic symbolic properties of life, thus preserving life-mind continuity in this context. 相似文献

The present paper proposes a definition for the complex polysemic concepts of consciousness and awareness (in humans as well
as in other species), and puts forward the idea of a progressive ontological development of consciousness from a state of
‘childhood’ awareness, in order to explain that humans are not only able to manipulate objects, but also their mental representations.
The paper builds on the idea of qualia intended as entities posing regular invariant requests to neural processes, trough
the permanence of different properties. The concept of semantic differential introduces the properties of metaphorical qualia as an exclusively human ability. Furthermore this paper proposes a classification of qualia, according to the models–with
different levels of abstraction–they are implied in, in a taxonomic perspective. This, in turn, becomes a source of categorization
of divergent representations, sign systems, and forms of intentionality, relying always on biological criteria. New emerging
image-of-the-world-devices are proposed, whose qualia are likely to be only accessible to humans: emotional qualia, where emotion accounts for the invariant and dominant property; and the qualic self where continuity, combined with the oneness of the self, accounts for the invariant and dominant property. The concept of
congruence between different domains in a metaphor introduces the possibility of a general evaluation of truth and falsity
of all kinds of metaphorical constructs, while the work of Matte Blanco enables us to classify conscious versus unconscious
metaphors, both in individuals and in social organizations. 相似文献

We show how simulated robots evolved for the ability to display a context-dependent periodic behavior can spontaneously develop
an internal model and rely on it to fulfill their task when sensory stimulation is temporarily unavailable. The analysis of some of the best
evolved agents indicates that their internal model operates by anticipating sensory stimuli. More precisely, it anticipates
functional properties of the next sensory state rather than the exact state that sensors will assume. The characteristics
of the states that are anticipated and of the sensorimotor rules that determine how the agents react to the experienced states,
however, ensure that they produce very similar behaviour during normal and blind phases in which sensory stimulation is available
or is self-generated by the agent, respectively. Agents’ internal models also ensure an effective transition during the phases
in which agents’ internal dynamics is decoupled and re-coupled with the sensorimotor flow. Our results suggest that internal
models might have arisen for behavioral reasons and successively exapted for other cognitive functions. Moreover, the obtained
results suggest that self-generated internal states should not necessarily match in detail the corresponding sensory states
and might rather encode more abstract and motor-oriented information. 相似文献

The discovery and use of antimicrobial agents in the last 50 yr has been one of medicine’s greatest achievements. These agents
have reduced morbidity and mortality of humans and animals and have directly contributed to human’s increased life span. However,
bacteria are becoming increasingly resistant to these agents by mutations, which alter existing bacterial proteins, and/or
acquisition of new genes, which provide new proteins. The latter are often associated with mobile elements that can be exchanged
quickly across bacterial populations and may carry multiple antibiotic genes fo resistance. In some case, virulence factors
are also found on these same mobile elements. There is mounting evidence that antimicrobial use in agriculture, both plant
and animal, and for environmental purposes does influence the antimicrobial resistant development in bacteria important in
humans and in reverse. In this article, we will examine the genes which confer resistance to tetracycline, macrolide-lincosamide-streptogramin
(MLS), trimethoprim, and sulfonamide. 相似文献

The existence of superstition and religious beliefs in most, if not all, human societies is puzzling for behavioral ecology.
These phenomena bring about various fitness costs ranging from burial objects to celibacy, and these costs are not outweighed
by any obvious benefits. In an attempt to resolve this problem, we present a verbal model describing how humans and other
organisms learn from the observation of coincidence (associative learning). As in statistical analysis, learning organisms
need rules to distinguish between real patterns and randomness. These rules, which we argue are equivalent to setting the
level of α for rejection of the null hypothesis in statistics, are governed by risk management as well as by comparison to
previous experiences. Risk management means that the cost of a possible type I error (superstition) has to be traded off against
the cost of a possible type II error (ignorance). This trade-off implies that the occurrence of superstitious beliefs is an
inevitable consequence of an organism’s ability to learn from observation of coincidence. Comparison with previous experiences
(as in Bayesian statistics) improves the chances of making the right decision. While this Bayesian approach is found in most
learning organisms, humans have evolved a unique ability to judge from experiences whether a candidate subject has the power
to mechanistically cause the observed effect. Such “strong” causal thinking evolved because it allowed humans to understand
and manipulate their environment. Strong causal thinking, however, involves the generation of hypotheses about underlying
mechanisms (i.e., beliefs). Assuming that natural selection has favored individuals that learn quicker and more successfully
than others owing to (1) active search to detect patterns and (2) the desire to explain these patterns mechanistically, we
suggest that superstition has evolved as a by-product of the first, and that belief has evolved as a by-product of the second. 相似文献
