Taste Buds and Receptors01:20

Taste Buds and Receptors

5.4K
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,...

Conditioned Taste Aversion01:14

Conditioned Taste Aversion

881
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

Regulation of Food Intake01:30

Regulation of Food Intake

2.9K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Behaviorism01:28

Behaviorism

6.0K
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

8.3K
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?

Area of Science:

  • Pediatric Psychology
  • Developmental Disabilities
  • Behavioral Interventions

Background:

  • Feeding problems are common in children with autism spectrum disorder (ASD).
  • A unique case of food-related prompt dependence was identified in a 6-year-old boy with autism.
  • The child required adult approval for each bite of food, significantly hindering independent eating.

Purpose of the Study:

  • To investigate a treatment for severe food-related prompt dependence in a child with autism.
  • To establish independent eating behaviors in a pediatric case study.
  • To demonstrate the efficacy of instructional strategies in overcoming feeding challenges.

Main Methods:

  • A single-subject design was employed to treat the food-related prompt dependence.
  • Instructions were systematically implemented, gradually increasing the number of bites required per eating interval.
  • The intervention involved fading prompts to promote self-initiated eating.

Main Results:

  • Baseline independent eating was extremely low, at approximately 0.67%.
  • Following the instructional intervention, independent eating increased to nearly 100%.
  • The final phase involved a generalized instruction, "eat your lunch," indicating successful treatment generalization.

Conclusions:

  • Systematic instruction is an effective method for treating food-related prompt dependence in children with autism.
  • Behavioral interventions can successfully establish independent eating skills in children facing significant feeding challenges.
  • This case highlights the potential for targeted strategies to improve eating behaviors and reduce reliance on external prompts.
