Questions and Answers

What is the Clever Hans Effect in relation to animal cognition?

  • The ability of animals to perform tricks on command.
  • A method of training animals for specific tasks.
  • A phenomenon where animals independently solve complex problems.
  • A situation where animals respond to human cues unintentionally. (correct)
  • How is fitness typically measured in real populations?

  • By comparing physical traits between species.
  • By calculating the genetic variance within a population.
  • Through surrogates like reproductive success and survival rates. (correct)
  • Through direct observation of mating success only.
  • What role does input matching have in sensory systems?

  • It facilitates response to environmental changes through adaptation.
  • It allows for the differentiation of stimuli based on learned responses.
  • It aids in filtering out irrelevant stimuli to focus on essential ones. (correct)
  • It ensures consistency in the perception of stimuli without alteration.

    Study Notes

    Animal Behavior Study Guide

    • Concepts from the first unit of animal behavior are listed.
    • This is not a complete list, but aims to help with reviewing key concepts.
    • Concepts should be related to each other and to animal behavior.

    Behaviorism

    • Reinforcement/Conditioning is a key concept.
    • Ethology: is another key concept

    Ethology Concepts

    • Proximate vs. ultimate hypotheses are important comparisons.
    • Anthropomorphism is a concept to consider.
    • Observational vs. experimental studies differ.
    • Objective vs. subjective observations need to be distinguished.
    • Ethogram is a method in ethology.
    • Scan sampling, focal animal sampling, and interval vs. continuous sampling methods.

    Evolution Concepts

    • Natural Selection, Mutation, Genetic Drift, and Gene Flow are essential concepts.
    • Evolutionary Trade-offs and Adaptation, Fitness, Epistasis, and Pleiotropy.
    • Phenotypic plasticity, Heritability, Artificial Selection experiment, and Genomewide association study (GWAS) are key terms.

    Additional Study Points

    • Twin Study: is a study method that is important to understand.
    • Umwelt: Consider this important biological concept
    • Input matching, Stimulus filtering, Clever Hans Effect, and cognition.
    • Limits to natural selection include evolutionary trade-offs and changing environments.
    • Nature vs. nurture is a concept to consider.
    • Experimental vs. observational studies differ.
    • Issues with Behaviorism need to be considered as a school of scientific thought.
    • Darwin's right and wrong concepts in evolutionary biology.
    • Gene-behavior relationships and data needed for natural selection.
    • Clever Hans Effect in animal cognition research.
    • Input matching and stimulus filtering in sensory systems (e.g., toad vision, bat echolocation).
    • Methods for measuring heritability and understanding evolutionary change are important.
    • Evolutionary factors influencing sensory systems and their functioning.
