Naturalistic Observations02:30

Naturalistic Observations

15.5K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Physiological Barriers01:25

Physiological Barriers

3.6K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

What is Behavior?00:54

What is Behavior?

9.0K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Criticisms of the Evolutionary Perspective

128
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

Ethics in Research

23.1K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Tonicity in Animals01:16

Tonicity in Animals

3.2K
Tonicity describes the amount of solute in a solution. The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells. In a hypotonic solution, such as tap water, the extracellular fluid has a lower concentration of solutes than the fluid inside...

Area of Science:

  • Wild animal welfare physiology
  • Animal behavior and physiology
  • Comparative psychology

Background:

  • Affective states are widespread in animals due to adaptive advantages.
  • Current animal welfare studies primarily focus on managed animals in non-natural settings.
  • Significant gaps exist in understanding wild animal affective states in natural environments.

Approach:

  • This article reviews the relationship between physiology and animal welfare in wild populations.
  • It emphasizes the benefits of using physiological markers for objective welfare assessment.
  • Limitations and best-practice recommendations for using physiological markers are discussed.

Key Points:

  • Physiological markers offer objectivity, comparability, and temporal data for wild animal welfare.
  • Peripheral physiological markers have complex relationships with affective states.
  • Multifactorial approaches and replication are vital for effective physiological assessment.

Conclusions:

  • There is a need for unifying theoretical and methodological frameworks for wild animal welfare research.
  • Integrating physiological markers can significantly advance the study of wild animal welfare.
  • This work lays the foundation for the emerging field of wild animal welfare physiology.
