The present study is an attempt to gain insights into working memory as an important component of L2 aptitude and to provide empirical evidence for the investigation of the relation between working memory and L2 vocabulary learning rate.
Introduction
Research has suggested that working memory (WM) plays a vital role in second language acquisition. (Mackey, Philp, Fujii, & Tatsumi 2002, Williams 1999). Many SLA researchers have proposed that WM is a central part of L2 aptitude or to some extent, WM even is an L2 aptitude (Robinson 2002, Skehan 2002). WM involves ‘the temporary storage and manipulation of information’ necessary for the operation of complex cognitive tasks (Hummel & Holyoak 2003); WM therefore is an indicator of our capacity for thinking and for language processing. The present study will be empirically examining the possible relation between WM working memory and L2 vocabulary learning to test the hypothesis that the capacity of WM is correlated with vocabulary learning rate.
Background of literature
A WM model first proposed by Baddeley and Hitch in 1974 consists of three basic components: the central executive, the phonological loop and the visual/ spatial sketchpad. In 2000 this model was extended with the multimodal episodic buffer. The central executive directs information to the three processes: the phonological loop, the visual/ spatial sketchpad, and the episodic buffer. The phonological loop stores audio information while the visual/ spatial sketchpad stores spatial and visual information. The episodic buffer is to integrate audio, visual, and spatial information.

The two most common aptitude tests administered for high school students are the Scholastic Aptitude Test (SAT) and American College Testing (ACT), devised to assess a student’s potential for success and readiness in college. However, experience is still regarded as important; school-related learning, particularly in language and mathematics, is a prerequisite for success on the tests. Because aptitude tests are regarded as reliable, they eliminate teacher bias and differences in teachers’ grading practices, thus, adding valuable information in predicting future college success. There is no widely accepted definition of “aptitude” and “ability,” and the terms are often used
In conclusion, Baddeley and Hitch (1974) developed the working memory in response to the multi store model and introduced four mechanisms involved; the phonological loop, visual-spaital sketchpad, episodic buffer and the central executive. The four components are also largely supported by a good wealth of evidence (in Smith, 2007).
Ebbinghaus’ work on memory performance contributed astonishing knowledge to the field of scientific psychology and enthralled several succeeding researchers and psychologists (Fuchs, 1997; Slamecka, 1985; Young, 1985). Ebbinghaus was precisely known for conducting memory experiments by using nonsense syllables, and from the results of those experiments, he postulated a unitary view of learning and memory. However, Endel Tulving, provided evidence from Ebbinghaus’ original research that there existed discernible kinds of learning and memory. Prior to his experiment, Tulving received some scathing criticism on his stance regarding Ebbinghaus’ research, but he averred that there was no intention to derogate its concept (Slamecka, 1985; Tulving, 1985). Rather, Tulving’s experiment emanated from Ebbinghaus’ original research to address implications that would supplement knowledge about the psychological science of memory.
Altogether this study has helped us learn more about the brain and memory. Learning is measured thorough when a student can reiterate the right answer to a question. In this study, students in one conditions learned forging language vocabulary words in standard example of recurrent study exam trials. In three other conditions, once a student had correctly formed the language item, it was constantly studied but dropped from further testing. Repeatedly tested but dropped from the further study or just dropped from both the study and also the test. The results reveal the critical part of retrieval practice in combining education and shows that even college students seem naive of the fact.
Baddeley (2002) contends that it is an attentional framework which facilitates action inside the working memory and controls the transmission of data between different parts of the psychological framework and in addition the phonological circle and visuo-spatial sketchpad. In any case, there is not a specific and correct clarification of this focal official framework (Andrade, 2001) and this is the shortcoming of the model (Andrade, 2001). Examining the correct procedure of the central executive is significant as it is on a very basic level imperative for the legitimacy of the working memory show all in all since it is in charge of various psychological capacities and the working memory display despite the fact that its slave frameworks of phonological circle and visuo-spatial sketchpad have been separately clarified and explored however the entire system still relies on the central executive. A Quality of the central executive is that it offers the clarification with connection to parts of formative and grown-up aptitudes (Andrade, 2001). Baddeley (2003) extends the central executive to the Norman and Shallice model of attentional control and specifically the supervisory articulatory framework (Baddeley, 2003 Baddeley, 2002). There is likewise a need on what really drives the framework (Baddeley, 2000, 2003) which is particularly intriguing as absolutely consideration may not be the reason but rather its cooperation with physical markers (Damasio,
Psychophysiological interactions analysis (PPI) was performed to examine whether individuals with varying working memory have different activity in brain regions. After that, partial correlation analysis was done on each pair of regions using mean signal intensity. According to Newman. SD, et al., (2013) the limitations of this study are related to default network and the use of a language comprehension task with three processing phases. No particular ethical considerations arose except for five participants who were excluded from this analysis due not having a complete dataset. In Chantel S. Prat & Marcel Adam Just (2013); however, the number of participants who took part in this study were 27 right-handed individuals including 15 male and 12 female. The participants age ranged between 18-25. Let it not remain unsaid that, 7 more participants were tested but they weren’t included in the analysis. According to Chantel S. Prat & Marcel Adam Just (2013) 60sentences were presented to participants under three different working memory conditions to test information
In order to understand how the capacity of working memory might be improved it is necessary first to define what is meant by working memory. According to the definition by Baddeley and Hitch (1976) working memory is a limited capacity system that actively holds information in mind in which these can be manipulated. It consists of four subsystems: a phonological loop, a visuospatial sketchpad, an episodic buffer and a central executive. The phonological loop has two components: the phonological store in which sounds are stored; and the articulatory control process which automatically refreshes these sounds in a 2-second cycle (Revlin, 2012). Because of this 2-second limitation the following rule applies: the more information to process, the more will be lost from working memory.
This essay will firstly briefly describe the theories and important facts about the original multi-store model of memory (MSM) and the working memory model (WMM).

Working memory involves temporarily storing information as well as temporarily manipulating information. Thus, working memory is essential to learning a new language since it involves both temporarily remembering information as well as manipulating the information (as in producing the sounds just learned). Some languages have shorter phonemes, which may be the reason why it would be easier to remember some things in some languages rather than others. The average number of phonemes in English is 2 compared to 3 in Spanish. Thus, WM is crucial to learning languages, however “WM is not a unitary process and different subsystems can be distinguished; at least, (a) an executive frontal process, and (b) a memory storage process related to the left temporal lobe,” according to Ardila (“Working Memory” 2014, p. 229). As a result, different subsystems of WM may work differently depending on whether it is the first language learned (L1) or the second, L2. There is evidence that WM in L2 are significantly more difficult than in

In this paper the writer is going to present an overview of the field of neurolinguistics which is the study of the mental faculties involved in the perception, production, and acquisition of language. In other words, the neurobiological factors that enable humans to acquire, use, comprehend and produce language.
It has been shown that Second Language Acquisition (SLA,) takes time and occurs in stages (Ferris, 1995). In addition, second language (L2) learners go through various stages of acquisition of different elements of the second language and they may make errors. These errors may be caused by inappropriate transference of first language patterns or by incomplete knowledge of the L2 (Ferris, 1995).
