1.1 Introduction
Language acquisition has been a subject of extensive research and debate within the field of psychology and linguistics. Two prominent theories that have shaped our understanding of how language is learned are Behaviorism and Mentalism. Behaviorism, advocated notably by B.F. Skinner, posits that language acquisition is primarily a result of conditioning, where verbal behavior is reinforced through exposure and response mechanisms. On the other hand, Mentalism, championed by Noam Chomsky, argues that innate cognitive structures play a fundamental role in language development, proposing that humans are biologically predisposed to acquire language through universal grammar principles.
This chapter will address the background information that motivated this study, the challenges that prompted it, its aim, and its objectives as a preface to subsequent sections of the study. Additional factors include the study's significance, scope, limitations, research questions, and the definition of technical terms.
1.2 Background of Study
The exploration of language acquisition theories, particularly Behaviorism and Mentalism, has evolved significantly over the decades, reflecting shifts in theoretical paradigms and methodological approaches. Behaviorism, pioneered by B.F. Skinner in the mid-20th century, initially dominated the discourse on language learning. Skinner's influential work, "Verbal Behavior" (1957), proposed that language development could be explained through principles of conditioning, emphasizing the role of environmental stimuli and reinforcement in shaping linguistic behavior.
In response to Behaviorism's deterministic view of language acquisition, Noam Chomsky introduced Mentalism as a theoretical alternative. Chomsky's seminal critique of Behaviorism and his proposal of universal grammar in "Syntactic Structures" (1957) marked a pivotal moment in linguistic theory. Mentalism posits that humans are innately equipped with cognitive structures that predispose them to acquire language, challenging Behaviorism's emphasis on external factors alone.
Since their inception, Behaviorism and Mentalism have sparked vigorous debate and empirical investigation within fields such as psychology, linguistics, and education. Scholars have sought to critically evaluate these theories, examining their respective strengths, limitations, and implications for understanding the complexities of language acquisition processes.
Behaviorism, championed by B.F. Skinner, emerged during the early 20th century and posited that language acquisition could be explained through principles of operant conditioning. Skinner's work, notably his book "Verbal Behavior" (1957), proposed that language emerges from reinforced associations between stimuli and responses, suggesting that environmental factors play a central role in shaping linguistic abilities.
In contrast, Mentalism, as articulated by Noam Chomsky, challenged Behaviorist principles by highlighting the role of innate cognitive structures in language acquisition. Chomsky's critique of Behaviorism and his proposal of universal grammar, first expounded in "Syntactic Structures" (1957), argued that humans possess inherent linguistic capacities that guide the acquisition of language, irrespective of external reinforcement. Therefore, in Nigeria where the research was carried out, the activities that was conducted is to examine the two of the theories of language acquisition (behaviourism and mentalism).
1.3 Statement of Problems
Investigation revealed that the study of language acquisition is marked by contrasting theoretical perspectives, prominently exemplified by Behaviorism and Mentalism. Behaviorism, articulated by B.F. Skinner in "Verbal Behavior" (1957), emphasizes the role of external stimuli and reinforcement in shaping linguistic behavior. In contrast, Mentalism, as proposed by Noam Chomsky in "Syntactic Structures" (1957), posits that innate cognitive structures and universal grammar principles are central to language acquisition, challenging Behaviorist principles.
These theoretical frameworks raise several critical questions and challenges.
- Firstly, how do the principles of Behaviorism and Mentalism differ in their explanations of language acquisition processes?
- Secondly, what empirical evidence supports or challenges each theory's claims regarding the mechanisms of language learning?
- Thirdly, what are the implications of these theories for educational practices and interventions aimed at facilitating language development in diverse populations?
Addressing these questions is crucial for advancing our understanding of how individuals acquire language and for informing educational strategies that foster effective language learning environments.
1.4 Aim and Objectives of Study
The aim of the study is to critically evaluate two prominent theories of language acquisition, Behaviorism and Mentalism, to deepen our understanding of how individuals acquire language. In achieving this aim, the following specific objectives were laid out as follows:
- To examine empirical evidence supporting or challenging the assumptions and predictions of Behaviorism and Mentalism regarding language acquisition;
- To analyze the implications of Behaviorist and Mentalist theories for educational practices and interventions aimed at enhancing language learning outcomes;
- To identify areas of convergence, divergence, and potential integration between Behaviorist and Mentalist perspectives on language acquisition; and
- To compare and contrast the theoretical principles of Behaviorism, as articulated by B.F. Skinner in "Verbal Behavior" (1957), and Mentalism, as proposed by Noam Chomsky in "Syntactic Structures" (1957).
1.5 Research Questions
The study came up with research questions so as to be able to ascertain the above stated objectives. The specific research questions for the study are stated below as follows:
- What are the fundamental principles and assumptions of Behaviorism and Mentalism in explaining language acquisition?
- How do Behaviorism and Mentalism differ in their predictions and explanations of language development processes?
- What empirical evidence supports or challenges the core tenets of Behaviorism and Mentalism in the context of language acquisition?
- What are the educational implications of Behaviorist and Mentalist theories for fostering effective language learning environments?
- To what extent can Behaviorist and Mentalist perspectives be integrated to provide a comprehensive understanding of language acquisition?

1.9 Definition of Terms
Behaviorism:
According to B.F. Skinner, Behaviorism is a psychological theory that posits learning as a result of conditioning through reinforcement and environmental stimuli (Skinner, 1957).
Mentalism:
Noam Chomsky's theory of Mentalism proposes that language acquisition is primarily governed by innate cognitive structures, such as universal grammar, which are intrinsic to human beings (Chomsky, 1957).
Language Acquisition:
It is the process by which individuals acquire and develop language skills, encompassing comprehension, production, and usage of a language system (Crystal, 1997).
Universal Grammar:
It is the proposed innate linguistic structure or set of principles that underlie the grammatical patterns and rules shared by all human languages, according to Chomsky's theory (Chomsky, 1965).
Operant Conditioning:
It is a behaviorist concept where behavior is shaped through reinforcement or punishment of responses to stimuli in the environment (Skinner, 1938).
