Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.3K
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....

Decision Making01:20

Decision Making

1.2K
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...

Reason and Intuition01:37

Reason and Intuition

7.7K
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...

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

19.0K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Information Processing Approach01:30

Information Processing Approach

717
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Decision Making: Traditional Method01:14

Decision Making: Traditional Method

5.7K
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Summary
This summary is machine-generated.

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) do not differ in choosing high-reward tasks but struggle to exert the necessary effort to complete them. This suggests effort-recruitment challenges, not reward-effort trade-off differences.

Area of Science:

  • Cognitive Neuroscience
  • Child Psychology

Background:

  • Effort allocation involves choosing and executing tasks based on perceived rewards.
  • Understanding these processes in children with Attention-Deficit/Hyperactivity Disorder (ADHD) is crucial for targeted interventions.

Purpose of the Study:

  • To investigate if children with ADHD exhibit altered reward-effort cost trade-offs.
  • To determine if children with ADHD face difficulties in executing effortful decisions.

Main Methods:

  • A cohort of 50 children (aged 9-15) with and without ADHD participated.
  • Participants made choices between high-effort/high-reward and low-effort/low-reward options.
  • Effort exertion was measured using a handheld dynamometer.

Main Results:

  • Children with ADHD and controls demonstrated comparable choices between reward-effort alternatives (p = .806).
  • Significantly fewer high-effort choices were successfully executed by children with ADHD compared to controls (p = .029).

Conclusions:

  • Children with ADHD do not appear to have a different reward-effort trade-off.
  • Difficulties in recruiting and sustaining effort, rather than decision-making, characterize ADHD in this context.
