1. Both first and second language learners pass through similar initial stages of language acquisition like a silent period and formulaic speech. They also acquire grammatical structures in a predictable order, with some structures being acquired earlier than others.
2. However, there are also important differences. First language learners rely solely on universal grammar, while second language learners' first language provides a basis for learning. Younger learners spend more time listening before speaking, while older learners can use metacognitive skills.
3. Factors like age, opportunity to practice with native speakers, and differences in universal grammar access can impact whether second language learners attain native-like proficiency, unlike first language learners.
Second Language Acquisition by David NunanParth Bhatt
The term second language acquisition (SLA) refers to the processes through which someone acquires one or more second or foreign languages. SLA researchers look at acquisition in naturalistic contexts (where learners pick up the language informally through interacting in the language) and in classroom settings. Researchers are interested in both product (the language used by learners at different stages in the acquisition process) and process (the mental process and
environmental factors that influence the acquisition process). In this chapter I trace the development of SLA from its origins in contrastive analysis. This is followed by a selective review of
research, focusing on product-oriented studies of stages that learners pass through as they acquire another language, as well as investigations into the processes underlying acquisition. The practical implications of research are then discussed, followed by a review of current and future trends and directions.

· As never before, people have had to learn a second language, not just as a pleasing pastime, but often as a means of obtaining an education or securing employment. At such a time, there is an obvious need to discover more about how second languages are learned. (学习二语的原因:why do you need to learn English? Is there have some special reason to learn [academic, daily life])
· ‘L2 acquisition’, then, can be defined as the way in which people learn a language other than their mother tongue, inside or out side of a classroom, and ‘Second Language Acquisition’ (SLA) as the study of this. [do you think you are a successful second language learner? Why? How you did it?]
· What are the goals of sla: learner language [how learners’ accents change over time. Another might be the words learners use; how learners build up their vocabulary.]
· What type of input facilitates learning? [do learners benefit more from input that has been simplified for them or from the authentic language of native-speaker communication?
· The goals of SLA, then, are to describe how L2 acquisition proceeds and to explain this process and why some learners seem to be better at it than others.

Yule: By the age of two-and-a-half, the child’s vocabulary is expanding rapidly and the child is initiating more talk while increased physical activity includes running and jumping. By three, the vocabulary has grown to hundreds of words and pronunciation has become closer to the form of adult language. At this point, it is worth considering what kind of influence the adults have in the development of the child’s speech.
Morphology; syntax
Lightbown: How do children accomplish this? What enables a child not only to learn words, but to put them together in meaningful sentences? What pushes children to go on developing complex grammatical language even though their early simple communication is successful for most purposes? Does child language develop similarly around the world? How do bilingual children acquire more than one language?

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Similarities and Differences

2. Introduction:
Psycholinguistics is a branch of study (cognitive science) which
combines the disciplines of psychology and linguistics. It is concerned
with the relationship between the human mind and the language as it
examines the processes that occur in brain while producing and
perceiving both written and spoken discourse .
Then the three main processes investigated in psycholinguistics are:
language comprehention , language production and language acquisition.
Language acquisition is the process by which humans acquire the
capacity to perceive and comprehend language, as well as to produce and
use words and sentences to communicate. Language acquisition is one
of the quintessential human traits, because nonhumans do not
communicate by using language. Language acquisition usually refers to
first-language acquisition, which studies infants' acquisition of their
native language. This is distinguished from second-language acquisition,
which deals with the acquisition (in both children and adults) of
additional languages.
Some scholars find it, in one sense, rather illogical to compare the
first language acquisition of child with the second language acquisition of
an adult. They state that it is much more logical to compare first and
second language learning in children or to compare second language
learning in children and adults. Though, most of traditional comparisons
have been made between first language acquisition in children and second
language acquisition in adults with the purpose to gain some valuable
insights from such comparisons. These insights can aid language teachers
to understand language learning and to assist their students in their
language learning process.
Similarities:
In both first and second language acquisition, universal grammar may
influence learning. In second language learning, universal grammar
may influence learning either independently or through the first language.
“There are two approaches to linguistic universals. The first approach was
put forward by Greenberg (1966, in Ellis 1994) and termed typological
3. universals. Typological universals are based on cross-linguistic
comparisons on a wide range of languages drawn from different language
families to discover which features they have in common (e.g. all
languages have nouns, verbs etc.). The second approach is the generative
school represented by Chomsky. The aim is to study individual languages
in great depth in order to identify the principles of grammar which
underlie and govern specific rules. This approach was later termed as
Universal Grammar (Ellis, 1994). The most relevant aspect of both
approaches that relates to L1 and L2 acquisition is that some features in a
language are marked and some are unmarked. According to typological
universals, unmarked features are those that are universal or present in
most languages and which the learners tend to transfer. Marked rules are
language specific features which the learner resists transferring. According
to Universal Grammar, core rules, such as word order, are innate and can
be arrived at through the application of general, abstract principles of
language structure .The findings show that unmarked features are learned
earlier and easier than marked rules in both the first and the second
language while unmarked forms require more time and effort by the
learner.” (Hulya IPEK, 2009 )
In both first and second language acquisition, there are predictable
stages, and particular structures are acquired in a set order. Individuals
may move more slowly or quickly through these stages, but they cannot
skip ahead .Researchers have carried out numerous studies to understand
the nature of first and second language acquisition. These studies have
revealed that both first and second language learners follow a pattern of
development, which is mainly followed despite exceptions. Rod Ellis
(1984) covers the idea of developmental sequences in detail and outlines
three developmental stages: the silent period, formulaic speech, and
structural and semantic simplification.
1.These studies
show that both first and second language learners
pass through a similar initial stage, the silent period. Children
acquiring their first language go through a period of listening to the
language they are exposed to. During this period the child tries to
discover what language is. In the case of second language
acquisition, learners opt for a silent period when immediate
production is not required from them.
2.The second developmental stage is termed formulaic speech.
Formulaic speech is defined as expressions which are learnt as
unanalysable wholes and employed on particular occasions (Lyons,
4. 1968, cited in Ellis, 1994). Krashen (1982) suggests that these
expressions can have the form of routines (whole utterances learned
as memorized chunks - e.g. I don't know.), patterns (partially
unanalyzed utterances with one or more slots - e.g. Can I have a
____?), and Ellis (1994) suggests that these expressions can consist of
entire scripts such as greetings. The literature points out that
formulaic speech is not only present in both first and second
language acquisition but also present in the speech of adult native
speakers.
3.In the third stage the first and second language learners apply
structural and semantic simplifications to their language.Structural
simplifications take the form of omitting grammatical functors (e.g.
articles, auxiliary verbs) and semantic simplifications take the form
of omitting content words (e. g. nouns, verbs). There are two
suggested reasons why such simplifications occur. The first reason is
that learners may not have yet acquired the necessary linguistic
forms. The second reason is that they are unable to access linguistic
forms during production. These three stages show us that L1 and L2
learners go through similar stages of development with the
exception that L2 learners are urged to skip the silent period.
However, learners do not only show a pattern in developmental
sequences, but also in the order in which they acquire certain
grammatical morphemes.
Acquisition Order:
Researchers have tried to find out if there is an order of acquisition in
acquiring grammatical morphemes.According to Brown ( 1973,cited
in McLaughlin, 1987 ) there is a common - invariant - sequence of
acquisition for at least 14 function words in English as a first
language -noun and verb inflections, prepositions, and articles.
Findings of these studies pointed out that there is a definite order in
the acquisition of morphemes in English first language learners.
Lightbown and Spada (2006) review studies which have proposed
that the acquisition of question words (what, where,who, why,
when, and how), show a great similarity in first and second language
acquisition. Based on the morpheme studies in L2 acquisition,
Krashen (1982) put forward the Natural Order Hypothesis which he
developed to account for
second language acquisition. He claimed that we acquire the rules of
language in a predictable order. The above arguments show that
there seems to exist an order of acquisition in both first and second
5. language acquisition. Hence, other scholars suggest that one should
be careful not to claim for an invariant order of acquisition but for a
more flexible order of acquisition and be aware of the variations
affecting this order such as sex, intelligence, social background, rate
of learning, and experience of linguistic interaction.
In both first and second language acquisition, making errors is a part
of learning. Learners need to make and test hypotheses about language to
build an internal representation of the language. In the initial stages of
learning, learners may use chunks of language without breaking them
down or processing them as independent units. In later stages, they may
make new errors as they begin to process the parts of each chunk
according to the rules of their language system. For example, a learner
may start out using the correct form of an irregular verb as part of a
language chunk, but later over generalize and place a regular affix on that
same verb.
In both first and second language acquisition, the learner uses context
clues, prior knowledge, and interaction to comprehend language.
In both first and second language acquisition, age is an important
variable affecting proficiency. The psychologist Eric Lenneberg argued that
there is a critical, biologically determined period of language acquisition
between the ages of 2 and 12 (McLaughlin, 1987). Originally the notion of
critical period was connected only to first language acquisition but later it
was applied to second language acquisition as well. Consequently, it is
argued that a critical period for second language acquisition is due until
puberty , beyond which people seem to be relatively incapable of acquiring
a native like accent of the second language
In both first and second language acquisition, learners can often
comprehend more complex language than they are able to produce. In
the initial stages of learning, learners go through a silent period.
In both first and second language acquisition, a learner's proficiency can
vary across situations.
In both first and second language acquisition, learners may over
generalize vocabulary or rules, using them in contexts broader than those
in which they should be used.
In both first and second language acquisition, learners need
comprehensible input and opportunities to learn language in context
in order to increase their proficiency. Stephen Krashen (1982) has put
forward the Input Hypothesis which reveals the importance he places on
6. input. He argues that the learner needs to receive comprehensible input to
acquire language. Information about the grammar is automatically
available when the input is understood. Krashen argues that the input a
first language learner receives is simple and comprehensible at the
beginning and is getting slightly more complicated. With this argument,
he supports his next argument that input should be slightly above the
level of the language learner (i+1). Only in doing so can the second
language learner move forward. He argues that the second language
learner should be exposed to the target language as much as possible and
that the lack of comprehensible input will cause the language learner to be
held up in his development (Ellis, 1994; McLaughlin, 1987).
Differences :
In first language acquisition, the basis for learning is universal
grammar alone. In second language acquisition, knowledge of the first
language also serves as a basis for learning the second language. There
may be both positive and negative transfer between languages in second
language learning.
In first language acquisition, children spend a long time listening to
language, babbling, and using telegraphic speech before they can form
sentences. In second language acquisition in older learners, learning is
more rapid and people are able to form sentences within a shorter period
of time.
In formal second language learning in older learners, learners are able
to use more metacognitive processes in their learning. They can
consciously analyze and manipulate grammatical structures, and they
can explicitly describe how language works. This can speed the learning
process.
Affective Considerations: The affective domain includes many factors
such as inhibition, attitudes, anxiety, and motivation. While anxiety and
motivation are mainly related to adult second language learning, child
first language learners have not developed or are just in the process of
developing such affective factors. While inhibitions pose no difficulty for
children acquiring their first or second language, they propose to be
intervening in adult second language acquisition. Inhibitions can be
defined as ego boundaries the person builds in order to protect his or her
ego. Mistakes can be seen as threats to one's ego. With the fear to make
7. mistakes the adult language learner can resist to speak in the classroom. A
second affective factor, which is formed by the cognitive development of a
person, that can make second language acquisition difficult for an adult is
attitude. Young children are not cognitively enough developed to possess
attitudes towards races, cultures, ethnic groups, and languages. As the
child reaches school age, attitudes are acquired. Stephen Krashen has
developed The Affective Filter Hypothesis to account for the effects of
affective variables on second language acquisition. He argues that affective
variables can act as a mental block, also termed affective filter, and
prevent comprehensible input to be absorbed. When the learner is
unmotivated and lacks confidence the affective filter goes up. When the
learner is not anxious and wants to be a member of the group speaking the
target language the filter goes down. He adds that children are at an
advantage when learning a first or second language because their affective
filter is low while adults are likely to have a higher affective filter due to
events that occurred in adolescence (Krashen, 1982; McLaughlin, 1987).
In second language learning in older learners, learners bring more life
experience and background knowledge to their learning. They have more
schemata and more learning strategies to help them learn the second
language.
In second language learning in older learners, there may be less access
to universal grammar, and sensitivity to phonological distinctions not
present in the native language will be reduced. Students learning in a
classroom setting may also have fewer opportunities to learn language
authentically. These factors may reduce the likelihood that second
language learners will attain native-like proficiency. First-language
learners always attain native proficiency, unless they have a disability that
affects language learning.
In first language acquisition, learners have many chances to practice
with native speakers (especially caregivers). In second language
acquisition, learners may or may not have the opportunity to
practice extensively with native speakers.
Psychomotor Consideration: These considerations try to explain the
reason why adult second language learners cannot obtain native-like
pronunciation in the second language. Starting from birth, speech muscles
gradually develop until after the age of 5. Then, until puberty the speech
muscles maintain their flexibility. Scientists argue that the flexibility of
children's speech muscles is the reason for why they can easily acquire
native-like pronunciation both in the first and in the second language. The
8.
decline of the flexibility in the speech muscles, however, prevents adult
second language learners to reach native-like pronunciation in the second
language (Brown, 1994).
Almost everyone acquires a first language, but not everyone acquires a
second language. Acquiring a first language happens naturally, while
acquiring a second language often requires conscious effort on the part of
the learner.
Conclusion:
To understand the nature of L1 acquisition, researchers have tried to
explain how children progress from "no language"to their mother tongue.
In L2 acquisition, however, the process is more complicated as learners
already have knowledge of their L1. The Interlanguage Theory plays a
crucial role in arriving at findings on how L2 learners move from their
mother tongue towards the target language. This means that we cannot
talk about the Interlanguage of a child but that we can talk about the
Interlanguage of the L2 learner.
Language learning to take place depends on various factors, which means
that the language teacher has to account for these factors as much as
possible. The above similarities and differences between first and second
language acquisition provide the language teachers with information to
aid them in their profession.This information can help the teacher in
designing classroom activities, designing the syllabus, choosing an
appropriate method, understanding the learning processes of his/her
students, and guiding his/her students in the language learning process.
However, none of the theories or factors advanced by researchers is on its
own explanatory enough to account for the complex process of language
learning. Every finding or explanation should be considered in interaction
with the others. This means that a language teacher cannot base his/her
teaching solely on any single theory or claim within the framework of L2
or L1 acquisition.
