The research world is not exempt from experiencing the consequences of globalization and massive exchange of information. Disciplines in both social and natural sciences are constantly developing, and their findings are shared with the different academic and scientific discourse communities through increasing amounts of Research Articles (RAs). Additionally, specialized journals are continuously being launched, not only in hard copy, but also online,. Researchers and professionals have, therefore, to be highly selective in their reading, often focusing on skimming abstracts and key words. Tseng (2011) suggests that “given their important roles and functions, abstracts, a specific genre in its own right, have received considerable attention and have been examined from different perspectives in recent years”(p.27). This paper compares and analyses two abstracts from the education field (King, 2002; Kokonis, 1993) and two abstracts from the medicine field (Becket et al., 2008; Wijeysundera et al., 2010), with the objective of clarifying the sometimes complex genre of RA abstracts.
According to the American Psychological Association (APA, 2010), an abstract is a brief, comprehensive summary of the contents of the original RA, which allows readers to survey the topics quickly in an accurate, non-evaluative, coherent, readable, and concise way. King (2002) and Kokonis (1993) abstracts seem to coincide with APA (2010) notion: a single paragraph containing from about 150 to 250 words. In this respect, Graetz (1982) explains that, an abstract should be a continuous narrative, written in whole sentences, not using separate paragraphs and following the exact order of the organization of the article. Swales and Feak (1994) also agree with this concept of Research Paper (RP) abstracts. They comment that “RP abstracts usually consist of a single paragraph containing from about four to ten full sentences” (p.210). In the case of King’s (2002) abstract, it is composed by five full sentences and Kokonis’ (1993) by seven full sentences.
However, Becket et al. (2008) and Wijeysundera et al. (2010) do not present the traditional format in their abstracts. Both are cases of structured abstracts, with named subheadings, which are common in medical published RAs, and which are gradually being required by many journals specialized in social and humanistic fields (Hartley, 1997; Haynes, Mulrow, Huth, Altman, & Gardner, 1990). According to Mosteller, Nave, and Miech (2004), the structured abstract allows for greater length than APA-style abstracts, providing a detailed and user-friendly framework to organize and display additional information. This structure usually results in a more robust abstract which can be understood independently of the main article. Becket et al. (2008) abstract contains nine sentences and Wijeysundera et al. (2010) eleven sentences. The sentences included in this type of abstract might not be fully complete due to the fact that subheadings already provide information about the content of each section (Mosteller, Nave, & Miech, 2004).
Several authors propose guidelines as to how abstracts should be structured and organized. Swales and Feak (n.d.) mention that, even though recent work in discourse analysis has investigated the number of rhetorical moves in abstracts, the common stages are five, which may vary in terminology, but which typically follow the same order: Move 1 background or introduction, Move 2 present research or purpose, Move 3 methods, materials, subjects, or procedures, Move 4 results or findings, and Move 5 discussion or conclusion. Two of the analysed abstracts, which belong to the education field, differ from the proposed moves. King (2002) presents an extended background move, followed by a purpose move, while Kokonis (1993) begins with a purpose move and continues with a long methods move. The reason for these variations might reside in the fact that both RPs are not experiential, but descriptive in nature.
In the case of structured abstracts, Haynes, Mulrow, Huth, Altman, and Gardner (1990) introduce detailed instructions for articles reporting original data from investigations with human subjects. They recommend an eight-move abstract with headings for objectives, design, setting, patients or other participants, interventions, main outcome measures, results, and conclusions. In the medicine abstracts analysed in this paper, Wijeysundera et al. (2010) present this structure without deviations, but Becket et al. (2008) seem to adhere to the moves proposed by Hartley (1997) and Swales and Feak (n.d.), since it includes headings for background, methods, results and conclusions. This divergence might reside in the fact that those articles belong to different specialized journals and their requirements regarding format might not be equal. Nakayama, Hirai, Yamazaki, and Naito (2005) indicate that eight-heading structured abstracts, might be more suitable for intervention studies than for observational studies.
Regarding the language of abstracts, Graetz (1982) provides a concise explanation of the main issues:
The abstract is characterized by the use of past tense, third person, passive, and the non-use of negatives. It avoids subordinate clauses, uses phrases instead of clauses, words instead of phrases. It avoids abbreviation, jargon, symbols and other language shortcuts which might lead to confusion. It is written in tightly worded sentences, which avoid repetition, meaningless expressions, superlatives, adjectives, illustrations, preliminaries, descriptive details, examples, footnotes. In short, it eliminates the redundancy which the skilled reader counts on finding in written language and which usually facilitates comprehension. (p.23)
The studied abstracts seem to accord with some of Graetz’s (1982) statements, but not with all of them. King’s (2002) abstract contains abbreviated words, such as DVD and VHS. Additionally, both medicine abstracts (Becket et al., 2008; Wijeysundera et al., 2010) contain detailed information, a typical feature of structured abstracts (Haynes et al., 1990).
Swales and Feak (1994) agree with Graetz’s (1982) description, but highlight that tense usage is complicated. The four abstracts (Becket et al., 2008; King, 2002; Kokonis, 1993; Wijeysundera et al., 2010) seem to follow Swales and Feak (1994) delineations: conclusions may be written in the present, opening statements in the present or present perfect, and results in the past tense. In Becket et al. (2008), the background section is written in present and present perfect, the methods and results in past, and the conclusions in present. Wijeysundera et al. (2010) differs, since the entire abstract is written in past, only in the conclusions the present was employed. King‘s (2002) opening statement is written in present perfect, while present is used in the rest of the abstract, and in Kokonis (1993), the whole abstract is written in present. Tseng (2011) notes that verb tense usage might fluctuate across disciplines and authors may vary their choice of verb tense depending on purpose and context.
It is undeniable that abstracts have become a fundamental part of RAs and they have proved to be a helpful resource in the selection of research literature, in order to manage the increasing information flow in the academic and scientific discourse communities. This study examined four RPs across disciplines from several perspectives. It is important to highlight the differences in format that were present in them. On the one hand, education journal abstracts employed the traditional paragraph-style narrative summary, while medical research journals used structured abstracts with subheadings. The shift in the style of abstracts used in medical journals forces writers to be more explicit about the content of their research, and to do this in a systematic and detailed way. These advantages might lead to major modifications in the education-related journals, since structured abstracts would offer individuals a vehicle to share, access, and communicate research findings though a format that efficiently compresses key information.
