  • 14 Learning, I: the Acquisition of Knowledge
    14 LEARNING, I: THE ACQUISITION OF KNOWLEDGE Most animals are small and don’t live long; flies, fleas, protists, nematodes and similar small creatures comprise most of the fauna of the planet. A small animal with short life span has little reason to evolve much learning ability. Because it is small, it can have little of the complex neu- ral apparatus needed; because it is short-lived it has little time to exploit what it learns. Life is a tradeoff between spending time and energy learning new things, and exploiting things already known. The longer an animal’s life span, and the more varied its niche, the more worthwhile it is to spend time learning.1 It is no surprise; therefore, that learning plays a rather small part in the lives of most ani- mals. Learning is not central to the study of behavior, as was at one time believed. Learning is interesting for other reasons: it is involved in most behavior we would call intelligent, and it is central to the behavior of people. “Learning”, like “memory”, is a concept with no generally agreed meaning. Learning cannot be directly observed because it represents a change in an animal’s potential. We say that an animal has learned something when it behaves differently now because of some earlier ex- perience. Learning is also situation-specific: the animal behaves differently in some situations, but not in others. Hence, a conclusion about whether or not an animal has learned is valid only for the range of situations in which some test for learning has been applied.

Publication Date 1989 License https://creativecommons.org/licenses/by/4.0/ 4.0 Peer reviewed eScholarship.org Powered by the California Digital Library University of California The International Journal of Comparative Psychology, Vol. 2, No. 3, Spring 1989 THE GENERAL PSYCHOLOGICAL CRISIS AND ITS COMPARATIVE PSYCHOLOGICAL RESOLUTION Charles W. Tolman University of Victoria ABSTRACT: The crisis in general psychology is identified as one of theoretical indeter- minacy. An important source of indeterminacy is the form of generalization that empha- sizes classification and common characters and identifies the general with the abstract. Determinate theory requires a form of generalization that identifies the general with the concrete and emphasizes genesis and interconnection. In order to overcome its crisis, general psychology thus requires the kind of evolutionary methodology that comparative psychology is, historically speaking, best prepared to provide. Science must begin w^ith that w^ith which real history began. Logical devel- opment of theoretical definitions must therefore express the concrete historical process of the emergence and development of the object. Logical deduction is nothing but a theoretical expression of a real historical development of the concreteness under study. (Ilyenkov, 1982, p. 200) The decade of the 1970s w^as a difficult period for comparative psychology. The troubles first became apparent somewhere around 1950 M^hen Frank Beach called attention, in a deploring tone, to our "excessive concentration" on a very limited number of species, especially the ubiq- uitous Rattus norvegicus.

  • IAABC Core Competencies
    IAABC Core Competencies The IAABC recommends animal behavior consultants be skilled in seven Core Areas of Competency: I. Assessment Skills II. General Knowledge and Application of Learning Science III. Species-Specific Knowledge IV. Consulting Skills V. General Knowledge of Animal Behavior VI. Biological Sciences as Related to Animal Behavior VII. Ethics Core competency is defined as “a skill needed in order to be successful at a job or other activity.”[1] Success as an animal behavior consultant depends on the ability of the consultant to accurately assess the function of an animal’s behavior, and implement effective behavior modification strategies in agreement with a Least-Intrusive, Minimally Aversive approach. Animal behavior consultants also should maintain a working knowledge of biology as it relates to animal behavior, an understanding of consulting and behavior change program management, and ethics as it relates to both animal behavior and human learning. I) ASSESSMENT SKILLS A. History taking skills and history assessment 1. Eliciting accurate information 2. Interpretation of information provided 3. Assessing owner interpretation of behavioral issues B. Behavioral observation skills 1. Accurate observation and interpretation of behaviors demonstrated by the animal 2. Ability to integrate information obtained by direct observation of the animal and the humans involved C. Apply and integrate any additional behavioral, historical, medical and physiologic information. © IAABC. All Rights Reserved. | www.iaabc.org 1 1.

In the context of foraging be havior, bees perform 2 forms of learning, latent (or observatory) and associative learning. Latent learning plays an important role in spatial orientation and learning during dance communication, but the mechanisms of this kind of learning are little understood. In associative learning, stimuli experi- enced immediately before the reward (usually sucrose solution) are memorized for the guidance of future behavior. Well-established paradigms have been used to characterize operant and classical conditioning. The classical conditioning of olfactory stimuli is a very effective form of learning in bees and has helped to describe the behavioral and physiological basis of memory formation.

  • Revisiting Tolman, His Theories and Cognitive Maps
    VOLUME 1 43 Cognitive Critique REVISITING TOLMAN, HIS THEORIES AND COGNITIVE MAPS AD A M JOHNSON Department of Psychology, Bethel University, St. Paul, Minnesota E-MAIL: [email protected] DA VID A. CROWE Department of Biology, Augsburg College, Minneapolis, Minnesota E-MAIL: [email protected] Accepted 16 November 2008 KEYWORDS cognitive map, behavior, rodent, Bayes’ theorem, inference, hierarchical learning ABSTRACT Edward Tolman’s ideas on cognition and animal behavior have broadly influenced modern cognitive science. His principle con- tribution, the cognitive map, has provided deep insights into how animals represent information about the world and how these repre- sentations inform behavior. Although a variety of modern theories share the same title, they represent ideas far different than what Tol- man proposed. We revisit Tolman’s original treatment of cognitive maps and the behavioral experiments that exemplify cognitive map- based behavior. We consider cognitive maps from the perspective of probabilistic learning and show how they can be treated as a form 44 RE V ISITING TOLMAN hierarchical Bayesian learning. This probabilistic explanation of cognitive maps provides a novel interpretation of Tolman’s theories and, in tandem with Tolman’s original experimental observations, offers new possibilities for understanding animal cognition. INTRODUCTION There is a basic question of why we should return to old papers and ideas about cognition. This question is all the more important when those papers and ideas predate so many conceptual and method- ological breakthroughs. The simple answer to our question is that it allows us to reframe our own perspectives on cognition. The de- scriptions, analogies, reasoning and insights of these original papers and their ideas are unfettered by our modern conceptual and meth- odological perspectives.

  • Spatial Learning: Conditions and Basic Effects V.D
    Psicológica (2002), 23, 33-57. Spatial Learning: Conditions and Basic Effects V.D. Chamizo* Universitat de Barcelona A growing body of evidence suggests that the spatial and the temporal domains seem to share the same or similar conditions, basic effects, and mechanisms. The blocking, unblocking and overshadowing experiments (and also those of latent inhibition and perceptual learning reviewed by Prados and Redhead in this issue) show that to exclude associative learning as a basic mechanism responsible for spatial learning is quite inappropriate. All these results, especially those obtained with strictly spatial tasks, seem inconsistent with O’Keefe and Nadel’s account of true spatial learning or locale learning. Their theory claims that this kind of learning is fundamentally different and develops with total independence from other ways of learning (like classical and instrumental conditioning -taxon learning). In fact, the results reviewed can be explained appealing on to a sophisticated guidance system, like for example the one proposed by Leonard and McNaughton (1990; see also McNaughton and cols, 1996). Such a system would allow that an animal generates new space information: given the distance and address from of A to B and from A to C, being able to infer the distance and the address from B to C, even when C is invisible from B (see Chapuis and Varlet, 1987 -the contribution by McLaren in this issue constitutes a good example of a sophisticated guidance system). 1. Introduction. Are both the “when to respond” problem and the “where to respond” one governed by the same, general associative laws? Or are they not? To debate the idea of a general learning mechanism is not new.
