IB Psychology – Biological Approach Practice Test

Emotion and memory are tightly connected through the limbic system. The amygdala evaluates how emotionally significant a moment is and communicates with the hippocampus to boost memory encoding when arousal is high. This means emotionally charged events tend to be remembered more vividly because the amygdala enhances the consolidation processes in memory formation. The hypothalamus then translates that emotional state into physiological arousal and autonomic responses, so the body prepares for action while the memory is being formed. The hippocampus supports forming and organizing the memory itself, giving it context and detail. In short, the limbic system links what we feel with how we remember and responds to that emotion with bodily changes. Functions like coordinating movement, balancing, or processing vision involve other brain areas such as the cerebellum or occipital lobe.
