Twin’s Characteristics on Second Language Acquisition

Abstract
This study was conducted in a very short duration by focussing on the twins’ characteristics in acquiring L2. The comparison and contrast were made of those fraternal twins who have different gender. The result from the observation showed distinctive characteristics which are mostly caused by gender and personality. It is not surprising although they are twins yet they grow as two different individuals. The female twin was good in productive skills and an extrovert person. She learnt by involving herself actively in the real situation such as communication and interaction while the male was the opposite. He prefered observing people and receiving an input. It results differently on their production. The female was more fluent and pronounced better while the male was more analytical and rich of diction.
INTRODUCTION
Although some scholars said that learners are not neglected to characteristic anymore, gaining information of this will be useful to maximize the process and produce the best result. There are many factors influencing learners’ success in acquiring a second language. A single factor cannot stand by itsself. Thus, they correlate each other. The framework of this elements was adopted from Bot, Lowie, & Verspoor (2000) and Harmer (2007b). According to them, learners characteristics are drawn into age, aptitude and intelligence, and attitude and motivation
Pre and perinatal environment (Lung, Shu, Chiang, & Lin, 2009) and social interaction (Thorpe, Rutter , & Greenwood , 2003) are mentioned as another factors influencing learners’ LA. Regarding twins, Mahieu (2011) compared them to singletons and found they are not as smart as singletons at the same ages (Mahieu, 2011; Voracek & Haubner, 2008). Although twins basically come from a single egg, which is fertilized by a single sperm to form one zygote but it then unexpectedly divides itsself into two separated embryos (Boklage, 2010; Fortuna, Goldner, & Knafo, 2010), they grow as two different individuals after birth. Related to this argument, there rises a question whether twins who live in the same environment and receive the same input have different ways in  acquiring a second language or not.
Fortuna, Goldner, & Knafo (2010) stated that twins do not really have different ages. However, an asian especially Indonesia stereotype of twins’ intelligence lies on their ages related to the first and second born child. The second born as the younger is considered smarter due to an academic achievement. Since they are born as two individuals, they show some differences in SLA. Countless studies have been conducted in gaining information on learners’ learning characteristics (Behabadi & Behfrouz, 2013; Hatami, 2013) and twins (Fortuna, Goldner, & Knafo, 2010; Lung, Shu, Chiang, & Lin, 2009; Mahieu, 2011; Thorpe, Rutter , & Greenwood , 2003). This present study intends to weld and link up with those two issues on the twins’ learning characteristics in acquiring L2. The specific questions are listed below.
1.      What different characteristics do the twins show in acquiring L2?
2.      How are their L2 production?
This present study is considered relevant for a strong reason. The number of twin birth is increasing every year and parents and teachers still assume that they are similar in any way including learning characteristics on SLA.
METHODOLOGY
Subjects
A pair of 7 years old fraternal twins was chosen yet they have different gender; female and male.  The female was the first born. Their mother tongue is Bahasa Indonesia and Bahasa Madura is spoken by people ouside the house.
Techniques and Instruments  
Observing the subject for two days was done. To enrich the information, recording was selected in the form of audio and audio-visual. Also, face-to-face semi-structured interview was addressed to them and their parents.
Procedures
The researcher conducted an observation on May, 12th - 13th 2018 to have an overview towards the twins’ daily activity at home. To derive the needed information, she stayed in their house. Hence, she did not only observe the subjects but also interact with them. To avoid the missing data, she recorded their activities. Interview with the twins was conducted in an informal way to avoid anxiety and rigidity and semi-formal situation about the twins learning characteristics and second language production to their parents.
FINDING AND DISCUSSION
The questions to be answered are (1) What different characteristics do the twins show in acquiring L2? (2) How are their L2 productions?
Before discussing the result of learners’ characteristics, it was found that those twins have different personality. The female twin is an extrovert person. She is confident enough to interact with a new person. Conversely, the male is introvert and needs more time to be close to someone else.
Regarding age, some theories and studies in the literature review show that the earlier they learn, the better it is. Since they are twins, there is no age contrast here yet the characteristics based on their age. The female often talked to her dolls and pretended that they were in a middle of a certain situation. Also, she once stood in front of mirror and talked to herself. Meanwhile, the male did the similar activity. He played the transformer robots and a godzilla and he narrated. He used more difficult vocabularies than the female.
.....The robot wear the shield to protect him from monster’s punch and use his sword to fight back. The monster dead and the hero win ....”
Since they show the similar way to practice speaking English by themselves, they show the same progress and ability. Based on the interview result with their parents, they always use their imagination and their parents provide them with several media such as toys, cartoon movies, songs, and games. Their parents also prevent them to play cross-gender games. Therefore, they speak based on their gender such as the female conversation was about disney, princess, house-keeping, gardening, cooking, etc, while the male prefered racing, robots, mechanics, architecture, etc. This result is in line with Pullen & Cole (2010)’s studies of convergence on multiliteracy that differing learners based on their gender will help them to grow based on what they have to do.  
Related to retention, the female watched a cartoon movie in the television. It was about three pigs and a wolf. Each pig wore a cloth with different colors. When her mother came, she directly told her about that movie with detail information. She was very communicative but was not able to express the moral value from the movie. Whereas, the male was able to. It seemed like she was a fluent speaker and he was an analytical person. Their parents related this differences on their handedness. The male was left-handed. This finding correlates with Ghayas & Adil (2007) that left-handed tend to think beyond and deeply.
The next characteristics are the combination of gender, motivation, and attitudes. Since the female tend to communicate in English more often than the male, her motivation showed greater. She showed her positive attitudes when she first met the researcher due to the ability to use English communicatively. She also implemented her knowledge through interaction. Surprisingly, she minimized code-mixing and code-switching and almost use English in all utterances. Since she learns through practice, her pronunciation is good. However, the male tend to receive an input rather than producing. His diction is more variegated yet he is not as fluent as her. He is a wise and tactical person and could organize his idea without being interupted by his speech speed.
The interview resulted directly proportional with the real interaction. They are basically well-motivated learners yet show their positive attitudes. The female was friendly and directly became an open person. She intended to be the center of any activity or conversation. Conversely, the male prefered listening to the researchers and anwering if he was asked. He prefer to be accompanied playing a game rather than being addressed some questions. Also, their parents agreed that the female showed her interest by expressing and involving herself into a situation. Meanwhile, the male was rarely being expressive. He indicated his interest by listening, analyzing, and doing what was being asked. Related to Larsen-Freeman & Long (2000)’s belief that female surpass male, it is probably true because female tends to maximize the use of productive skills whereas male prefers receptive skills. Thus, people might think that they who are more productive is better in academic achievement yet they show different development. 
Summary and Implications
The result showed that the characteristics were mostly influenced by gender which was be framed through the ages, motivation, and attitudes. The female twin tends to be more expressive and active than the male. She learns by practicing and involving herself in each interaction and communication so her pronunciation is good. Whereas, the male tends to be more quiet and analytical and prefer receiving an input to producing a speech. Thus, his diction wa more variegated. Despite this differences, they are both well-motivated and show their positive attitudes on their own way.
Although they are twins, they have different characteristics in SLA. Parents and teachers who are involved in teaching and learning activity should know this well. Constrasting and comparing deeply on how different they are may rise a problem. The female twin who is more active is always considered as acquiring better and discriminate the male. This study expect that both teachers and parents realize in what way they acquire and develop.
