Fixed Action Patterns01:06

Fixed Action Patterns

15.8K
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.

Reason and Intuition

6.3K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

451
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment

194
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

77
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Decision Making01:20

Decision Making

85
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Summary

Impulse control issues in Parkinson's disease (PD) differ between actions and choices. Impulsive actions appear early, while choice impairments may emerge with medication, highlighting distinct progression patterns.

Area of Science:

  • Neuroscience
  • Neurology
  • Behavioral Science

Background:

  • Parkinson's disease (PD) presents with motor symptoms and non-motor issues, including impulse control deficits.
  • Existing research often examines impulsive action and impulsive choice separately, limiting a full understanding of impaired impulse control in PD.

Purpose of the Study:

  • To review and integrate findings on impulsive action and impulsive choice in Parkinson's disease.
  • To explore the influence of dopaminergic medication and disease progression on these distinct impulsivity domains.

Main Methods:

  • Qualitative review of behavioral studies assessing impulsive action and choice in Parkinson's disease samples.
  • Analysis of findings considering medication status (on/off dopaminergic medication) and disease stage.

Main Results:

  • A distinction exists between impulsive action and impulsive choice in PD.
  • Impulsive action deficits are evident in early, non-medicated PD and persist.
  • Impulsive choice impairments may be associated with dopaminergic medication, with limited data in non-medicated individuals.

Conclusions:

  • Impulse control in Parkinson's disease involves distinct trajectories for action and choice.
  • Further research is needed, particularly longitudinal studies, to clarify the impact of medication and disease progression.
  • Future studies should integrate both impulsive action and choice tasks within the same Parkinson's disease samples.
