Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

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....

Interference and Decay

Interference and Decay

Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Summary

This summary is machine-generated.

Errors in unrelated tasks impair visual attention. This study shows that errors reduce the N1 component (endogenous attention) and, in some cases, the P3 component, affecting early visual processing.

Area of Science:

Cognitive Neuroscience
Psychology
Neuroscience

Background:

Errors in unrelated tasks can disrupt subsequent cognitive performance.
Unexpected error events interfere with information processing and attentional mechanisms.

Purpose of the Study:

To investigate the impact of errors on early visual event-related potential (ERP) components.
To examine the duration of negative after-effects of errors on visual processing.

Main Methods:

Combined a flanker task with a visual discrimination task.
Manipulated the intertrial interval (ITI) between tasks.
Measured event-related potentials (ERPs), specifically N1 and P3 components.

Main Results:

Error trials significantly decreased the amplitude of the N1 component, reflecting impaired endogenous attention, regardless of ITI.
P3 component amplitude was attenuated following error trials, but only when the ITI was long.
These findings suggest low-level attentional processes are impaired after errors.

Conclusions:

Errors disrupt early visual processing by attenuating attention-related ERP components.
The N1 component is sensitive to error after-effects, indicating immediate impacts on attention.
The P3 component's attenuation suggests longer-lasting effects on cognitive processing, particularly with extended intervals.
