The statement reflects on the speaker's grim upbringing, suggesting they were deprived of genuine care and nourishment. Instead of being nurtured, they were exposed to stimuli that only sparked a faint interest in life, leaving them emotionally starved. The phrase "lukewarm appetitive stimuli" implies a lack of warmth and vitality in their experiences.
Additionally, the speaker describes their upbringing as one devoid of true affection. Rather than feeling loved, they experienced a calculated type of intimacy that was devoid of warmth. The speaker’s unconditioned reflexes being broken indicates a manipulation of their natural responses, suggesting an environment where authentic emotions and reactions were suppressed to create a façade of commitment.
