Alpha response reveals attention abnormalities in psychopathy.

Area of Science:

• Neuroscience
• Psychology
• Cognitive Science

Background:

• Psychopathy is linked to abnormal attention allocation during goal pursuit.
• The precise mechanisms of attention deficits and their neurocognitive effects in psychopathy are not fully understood.

Purpose of the Study:

• To investigate the relationship between psychopathy and attention allocation during a cognitive task.
• To explore the neurocognitive consequences of attention abnormalities in psychopathy.

Main Methods:

• Utilized electroencephalogram (EEG) to measure brain activity.
• Employed a continuous performance task in 61 adolescents and young adults.
• Analyzed parieto-occipital and central alpha activity in relation to psychopathy levels.

Main Results:

• Individuals higher in psychopathy showed enhanced parieto-occipital alpha suppression, indicating overallocated attention to visual cues.
• This overallocation was associated with blunted central alpha activity during NoGo trials, suggesting reduced neural resources for motor control.
• A unique attention allocation pattern in psychopathy was identified, prioritizing goal-relevant information.

Conclusions:

• Psychopathy is associated with a distinct pattern of attention allocation.
• This pattern redirects neural resources, impacting downstream cognitive functions like motor control.
• Findings clarify the neurocognitive underpinnings of attention abnormalities in psychopathy.
