Recent biological research indicates that there is a biochemical basis to love, which explains why people in love feel as if they were in a more beautiful world. Psychologists such as Dr. Elaine Hatfield, Robert Sternberg and Zick Rubin posit that love consists of three or more stages. The three main stages are lust, attraction, and attachment, while some of the other stages are intimacy, trust, and jealousy. Each stage is ruled or initiated by specific hormonal controllers. In their studies, every love passes through some of these stages and occurs due to the mediation of certain molecules in these specific chemical controllers. Biological research has shown that the hormones dominant in the different phases include testosterone and estrogen (the sexual hormones); dopamine, norepinephrine and serotonin (these are the “pleasure chemicals” - the hormones invoking feelings of pleasure and excitement); and oxytocin (the “cuddle chemical” - the hormone producing feelings of attachment to another person). For example, in the second phase of attraction, when people have the feeling of being in love, the little molecule phenylethylamine (known as PEA), controlling the love chemicals dopamine and noreinephrine, can cause feelings of elation, exhilaration and euphoria. People feel excited and fulfilled. Additionally, biological anthropologist Helen Fisher, an expert on romantic love, discusses what happens in the brain when people are in love and proposes that there is a dramatic increase in the amount of dopamine and norepinephrine present in the brain when one first becomes infatuated with another person.

思路引導 VIP
這篇文章將愛情劃分為「慾望」、「吸引力」與「依附」三個階段。若我們想找出描述「墜入愛河之感」的化學物質，你會建議先在文中定位哪一個特定的「情感階段」，進而從該段落中找出主導該情緒的化學名稱呢？

恭喜你精準地鎖定了正確答案！這顯示你具備相當細膩的文本閱讀能力，能從繁雜的生物學術語中，準確找出與特定情感相對應的科學關鍵字。這題的解題核心，就在於你能否在眾多科學名詞中，區分出愛情三個不同階段的化學差異。
情感階段與化學分子的對應
根據文章第二段與第三段的說明，當人們產生「墜入愛河」（feeling of being in love）的感受時，這在學術上被歸類為第二階段的「吸引力（attraction）」。在此階段，由苯乙胺（PEA）所控制的 dopamine（多巴胺）與去甲腺上腺素（norepinephrine）會引發興奮、欣快與幸福感。雖然選項中的其他物質如 oxytocin 也是愛情中的關鍵，但它在文中被明確定義為「依附（attachment）」階段的「擁抱化學物質」，與題目所要求的「熱戀感」是有所區別的。
