How are learned behaviors transferred to the basal ganglia?

As we repeatedly perform a behavior, the neural connections in the transcortical pathways become stronger. This strengthens the neural pathways in the basal ganglia, leading to the behavior becoming more automatic.

How do operant conditioning pathways work?

Operant conditioning involves learning through associations between behaviors and their consequences. The transcortical pathways are involved in initially learning new behaviors, while the basal ganglia take over as the behavior becomes more automatic.

Feather Pecking (FP)

A harmful behavior in chickens where they peck at and pull out feathers from other birds, often leading to injury and death.

What is the relationship between dopamine and reinforcement?

Dopamine release is a key mechanism in reinforcement, as it signals reward and motivates the repetition of behaviors associated with positive outcomes. This process is essential for learning and adaptation.

How does the nucleus accumbens contribute to reinforcement learning?

The nucleus accumbens integrates information about rewards and actions, allowing animals to learn and associate specific behaviors with pleasurable outcomes. This process drives motivated behavior.

What is behaviour?

Behaviour is the internally coordinated responses (actions or inactions) of whole living organisms (individuals or groups) to internal and/or external stimuli, excluding responses more easily understood as developmental changes.

Criteria of behaviour definitions

A good behaviour definition should be operational, essential, widely applicable, and succinct.

What are the problems with defining behaviour?

There is no one universally agreed-upon definition of behaviour, with over 50% of experts disagreeing on crucial aspects. This makes it difficult to tackle significant moral/emotional problems and to conduct rigorous scientific inquiry.

Why defining behaviour matters

A clear definition of behaviour is crucial for understanding and addressing important moral and emotional issues, as well as for conducting rigorous scientific research. It allows for the development of consistent and reliable methods for studying behaviour.

What does 'operational' mean in a behaviour definition?

An operational definition allows us to clearly decide whether something is or isn't behaviour based on specific criteria. It sets boundaries and helps us categorize phenomena.

What is the 'essential' part of a behaviour definition?

The essential part of a definition reflects the common understanding of the word. It captures the core features that people generally associate with the term.

What is meant by a behaviour definition being 'widely applicable'?

A good definition should apply to any living organism, avoiding bias towards specific types of animals. It should be general enough to encompass the diverse range of behaviours observed in nature.

Why is a 'succinct' behaviour definition important?

A succinct definition uses only essential words, avoiding unnecessary jargon or complexity. It makes the concept easier to understand and remember.

Starr and Taggart's Definition

Behavior is a response to stimuli (internal and external) involving sensory, neural, endocrine, and effector components. It's genetic and subject to natural selection, but can be modified by experience.

Grier and Burk's Definition

Behavior encompasses any observable or measurable muscular or secretory responses (or their absence) in response to internal or external environmental changes.

Hall and Halliday's Definition

Behavior involves the interplay between an animal's internal machinery (muscles, nervous system, etc.) and its external environment (food, enemies, social interactions).

Behavior Definition Challenge

Defining behavior is challenging because it encompasses a wide range of actions, from simple reflexes to complex social interactions.

Study Notes

General Information

  • The images show various scientific illustrations, a pig, and a photo of a turkey.
  • The information is likely from veterinary school lecture notes or other educational materials.
  • Topics discussed include animal behaviour, definitions of behaviour, observations of behaviours. Methods of study and analysis, measurement, and specific examples.

Animal Behavior

  • This section focuses on how to define animal behavior and the various components involved.
  • The slides discuss what constitutes animal behaviors and how animal behaviours interact with the environment.
  • The sections highlight different approaches to studying animal behaviour.

Methodology and Measurement

  • The slides describe various methodologies and techniques in animal behavior research.
  • These include defining specific behaviors, creating detailed recording schemes, collecting data, and different ways of classifying behaviors.
  • The sections talk about using time parameters (duration, frequency, latency, and bouts), and various factors affecting observers.
  • Different recording methods (e.g., continuous recording, point sampling, instantaneous sampling, one-zero sampling) are described.
  • The notes discuss human bias and suggest methods to avoid it during study
  • Some instruments like force plates, accelerometers, RFID, and video cameras are mentioned in the videos.

Study examples

  • Pig behaviors in different husbandry environments, like pens or pasture, are included. Videos of grazing behaviour of pigs are shown.
  • Behaviors of chickens are also included.
  • Images showing lambs feeding is included.
  • Pictures of pigs, and other animals, being observed were shown.
  • Examples include how animals may exhibit fear-related behaviours when encountering a strange or new animal, or how observing another animal (e.g., a mother) may lead to modified behaviour.
  • A case study showing that the "Clever Hans" phenomenon (human unconscious cues influencing animal behavior) must also be considered in animal studies.
  • The physiological factors and brain activity are talked about with the associated consequences and behaviour exhibited due to physical stimuli or cues.
  • Information on how animals react to their environment and learn is discussed.
  • Descriptions of different types and purpose of animal behaviour tests are shown (e.g., resident-intruder paradigm, the novel-object test, the startle test).
  • Slides show diagrams of neural pathways and hormonal actions related to aggression and fear response. Other tests used to study animals' learned behaviours related to fear, such as the tonic immobility test
  • Slides show examples of different types of aggression (predatory, defensive, inter-male, and maternal), and factors related to aggression.
  • The text emphasizes a critical need to consider environmental context and validity.
