Studies have shown the potentials of reading on the development of language. Especially, the literature on second language reading is replete with evidence that unearths the incidental acquisition of vocabulary through reading. Free and pleasurable reading, which has a marked effect on the frequency of reading, contributes significantly to the incidental acquisition of vocabulary. However, only a few studies have explored the interconnection among vocabulary acquisition, free and/or pleasure reading, and the reading frequency. To this end, this study manifests the incidental acquisition of vocabulary through reading and foregrounds the importance of free reading, reading pleasure, and reading frequency for vocabulary development. By confirming the strong correlation between reading frequency and the vocabulary test scores of the participants we attest that the reading frequency is significantly associated with free and/or pleasure reading (in our case, liking towards self-selected reading). We also theoretically contextualize and support the argument of incidental vocabulary learning through reading from a biological perspective. Given that the acquisition of any language subskill is enabled by the amalgamation of nature and environment, insights into the biological system of reading implicates a better understanding of the incidental acquisition of vocabulary through reading.

通过阅读了解偶然习得词汇的稳健性：来自生物语言学的定性见解

研究表明阅读对语言发展的潜力。尤其是，关于第二语言阅读的文献中，有大量的证据揭示了通过阅读偶然获得词汇的过程。自由愉快的阅读对阅读频率有显着影响，对词汇的偶然习得有显着的促进作用。然而，只有少数研究探讨了词汇习得、自由和/或快乐阅读以及阅读频率之间的相互联系。为此，本研究通过阅读来体现词汇的偶然习得，并突出了自由阅读、阅读乐趣和阅读频率对词汇发展的重要性。通过确认阅读频率与参与者词汇测试分数之间的强相关性，我们证明阅读频率与自由和/或快乐阅读（在我们的例子中，喜欢自选阅读）显着相关。我们还在理论上从生物学的角度对通过阅读偶然学习词汇的论点进行了背景化和支持。鉴于任何语言子技能的获得都是通过自然和环境的融合实现的，对阅读生物系统的洞察意味着对通过阅读偶然获得词汇的更好理解。我们还在理论上从生物学的角度对通过阅读偶然学习词汇的论点进行了背景化和支持。鉴于任何语言子技能的获得都是通过自然和环境的融合实现的，对阅读生物系统的洞察意味着对通过阅读偶然获得词汇的更好理解。我们还在理论上从生物学的角度对通过阅读偶然学习词汇的论点进行了背景化和支持。鉴于任何语言子技能的获得都是通过自然和环境的融合实现的，对阅读生物系统的洞察意味着对通过阅读偶然获得词汇的更好理解。
