Summary
High punishment sensitivity correlates with increased procrastination. This is linked to weaker emotional self-control in a brain network involving the caudate nucleus and middle frontal gyrus.
Area of Science:
- Neuroscience
- Psychology
- Behavioral Science
Background:
- Procrastination involves voluntarily delaying actions despite negative outcomes.
- Previous research links procrastination to punishment sensitivity, where higher sensitivity increases negative task utility.
Purpose of the Study:
- To investigate the neural substrates underlying the relationship between punishment sensitivity and procrastination.
- To test if a network connecting the caudate nucleus and prefrontal cortex mediates this relationship.
Main Methods:
- Utilized voxel-based morphometry (VBM) and resting-state functional connectivity (rsFC) in 268 participants.
- Examined gray matter volume and functional connectivity within specific brain regions.
Main Results:
- A strong positive correlation was found between punishment sensitivity and procrastination.
- Right caudate gray matter volume positively correlated with punishment sensitivity.
- Caudate-MFG connectivity negatively correlated with punishment sensitivity, mediating the link to procrastination.
Conclusions:
- Higher punishment sensitivity is associated with weaker emotional self-control.
- The caudate-MFG network plays a crucial role in mediating the effect of punishment sensitivity on procrastination.

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

167
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....

01:08Timing and Consequences on Behavior
145
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...
