Fixed Action Patterns01:06

Fixed Action Patterns

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Attention-Deficit/Hyperactivity Disorder

998
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Muscles of the Eye01:20

Muscles of the Eye

4.4K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Accessory Structures of the Eye

3.7K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

6.0K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Summary
This summary is machine-generated.

Regret, unlike disappointment, acts as a learning signal by comparing chosen outcomes with alternatives. This study used eye-tracking to show how regret influences decision-making and information processing.

Area of Science:

  • Cognitive Neuroscience
  • Decision Science
  • Behavioral Economics

Background:

  • Disappointment arises from comparing outcomes to expectations.
  • Regret, involving comparison with alternative actions, serves as a crucial learning signal.
  • Previous research indicates both anticipated and experienced regret influence decisions, with regret eliciting stronger emotional responses.

Purpose of the Study:

  • To investigate the role of regret in decision-making using eye-tracking.
  • To differentiate the mechanisms of disappointment and regret.
  • To explore the adaptive function of regret as a learning signal.

Main Methods:

  • Utilized a probabilistic lottery task with eye-tracking to monitor information acquisition.
  • Implemented partial and complete feedback conditions to induce or omit opportunities for regret.
  • Collected subjective ratings alongside eye-tracking data.

Main Results:

  • Decision-making patterns indicated assessment of anticipated regret and expected values.
  • Eye-tracking confirmed participants compared outcomes with non-chosen lotteries in complete feedback, especially after losses.
  • Increased counterfactual comparisons correlated with higher anticipation of regret.

Conclusions:

  • Regret involves active comparison with unchosen alternatives, particularly after negative outcomes.
  • Visual attention patterns reflect the assessment and anticipation of regret.
  • Findings support the adaptive, learning-oriented function of regret in decision-making.
