Instinctive Drift01:05

Instinctive Drift

1.2K
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

Taste Buds and Receptors

5.9K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Behaviorism

7.7K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Confirmation Biases01:31

Confirmation Biases

8.6K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

What is Behavior?00:54

What is Behavior?

10.4K
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.

Introspection01:29

Introspection

419
Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...

Area of Science:

  • Physiology
  • Neuroscience
  • Behavioral Science

Background:

  • This abstract summarizes a 50-year career dedicated to understanding ingestive behavior, the complex processes governing eating and drinking.
  • The research journey began with studies on thirst mechanisms in animal models and progressed to human studies on sensory-specific satiety and dietary obesity.

Observation:

  • Early work characterized thirst sensations and regulatory mechanisms in both animals and humans.
  • Studies investigated the impact of dietary variety on intake, leading to the concept of sensory-specific satiety.
  • Recent research focuses on how food properties—macronutrients, variety, portion size, and energy density—affect intake, satiety, and body weight in adults and children.

Findings:

  • Food properties significantly influence eating behavior, satiety, and body weight regulation.
  • Dietary variety plays a crucial role in modulating food intake and preventing overconsumption.
  • Systematic studies have elucidated the effects of macronutrients, portion size, and energy density on ingestive behavior.

Implications:

  • Understanding ingestive behavior is key to addressing public health challenges like obesity.
  • Leveraging factors such as variety, portion size, and energy density can promote healthier eating patterns.
  • This work aims to inspire future scientists to contribute to the field of ingestive behavior research.
