Motivation and Reward

Neuronugget #3

Excessive screen time can impact dopamine levels in several ways:

1. Impoverished Stimulation: Much of what happens on screens provides “impoverished” stimulation compared to real-world experiences. This affects the developing brain, which constantly builds neural connections.

2. Sleep Disruption: Blue light-emitting screens (like smartphones) suppress melatonin secretion, disrupting sleep patterns. Those who stay up late texting may lack essential REM sleep for memory consolidation.

3. Reward System Activation: Seductive digital activities (gaming, social media) activate the brain’s reward system. Variable reward mechanisms keep users engaged, but impoverished brains lack fully developed self-control.

4. Dopamine Addiction: Excessive screen time strains the reward system, making it harder to experience joy from natural sources. Brains crave more dopamine while producing less naturally, potentially leading to addictio.

5. Depression and Anxiety: Chronic screen time, releasing excess dopamine without sufficient breaks, may increase the risk of depression and anxiety.

However REAL LIFE social interactions are super duper for our motivation and reward mechanisms

1. Social Rewards: Positive social interactions activate the brain’s reward system, releasing dopamine. Whether it’s a hug, laughter, or a friendly chat, these interactions boost our mood and motivation.

2. Bonding and Trust: Oxytocin, another neurotransmitter, is released during social bonding. It enhances trust and social connections, indirectly influencing dopamine pathways.

3. Loneliness and Dopamine: Loneliness or social isolation can lead to reduced dopamine receptor availability. Chronic loneliness may alter dopamine signaling, affecting mood and well-being.

4. Feedback and Validation: Social feedback (praise, recognition) triggers dopamine release. Validation from others reinforces positive behaviors.

5. Social Hierarchies: Social status impacts dopamine. Achieving higher status activates reward pathways, while losing status can lead to stress and reduced dopamine.

We need to understand this to create the right kind of supportive and dopamine enhancing environments for all to thrive.

We get one of these little pings on our smartphones, and we get a little hit of dopamine as well. We get excited. We feel anticipation. As we feel this, we want it more and more. So we spend more and more time looking at our phones
