Final answer:
Lack of fulfillment of the three basic needs as per SDT can cause psychological distress and impact well-being. Insufficient food, water, and shelter can lead to severe health risks, quality of life degradation, and in extreme cases, death.
Step-by-step explanation:
When basic needs are not fulfilled according to Self-Determination Theory (SDT), it can lead to a range of negative consequences. This theory emphasizes the importance of satisfying three innate psychological needs: competence, autonomy, and relatedness.
If these needs are not met, individuals may experience psychological distress, impacting their overall well-being and happiness. For example, lack of competence may result in feelings of inadequacy, while insufficient autonomy can lead to feelings of being controlled or pressured. A deficit in relatedness may lead to social isolation or loneliness.
The absence of food, water, and shelter can have even more dire consequences. Without access to these basic resources, as indicated by the UN's Sustainable Development Goals, individuals face significant health risks and lowered quality of life. In extreme cases, shortages in resources like water can lead to agricultural collapse, job losses, armed conflict over resources, and even death.
