Discusses the debate surrounding the Critical Period Hypothesis in second language acquisition, which suggests that there may be a biological schedule after which L2 acquisition processes and outcomes are fundamentally altered
Case Studies
Presents case studies of successful late L2 learners like Julie and Laura, challenging the notion of a critical period for L2 acquisition
Rate and Ultimate Attainment
Explores the questions of rate and ultimate attainment in L2 learning, highlighting the variations in individual language learning processes related to age
Age Effects
Discusses how age can impact the speed and extent of language learning, contrasting the relatively uniform nature of monolingual first language acquisition with the variability in L2 acquisition
Emphasizes the universal influences of age on L2 acquisition and the ongoing challenges in understanding the relationship between age and L2 learning
Interlanguage
The language system constructed by learners at different stages of L2 acquisition
L1 Transfer
Explores how learners transfer linguistic features from their first language to the new language, leading to both positive and negative effects on L2 learning
Similarities and Differences
Delves into how learners navigate the similarities and differences between languages during the acquisition process
Interlanguage Processes
Discusses the cognitive and linguistic processes involved in the development of a learner's language
Variability and Systematicity
Explores how learners exhibit variability in their language development while also demonstrating systematic patterns in their interlanguage
Morphosyntactic Development
Examines the patterned attainment of morphological accuracy and the emergence of tense and aspect in L2 morphology
Acculturated Attitudes
The importance of learners' attitudes towards the target language and culture, suggesting that acculturation can play a significant role in language learning success
Comprehensible Input
The significance of providing learners with input that is understandable and meaningful, highlighting the role of input in facilitating language acquisition
Negotiated Interaction
How interaction and negotiation for meaning contribute to language learning, emphasizing the importance of meaningful communication in the acquisition process
Pushed Output
The concept of pushed output, where learners are encouraged to produce language beyond their current proficiency level, promoting language development through active use
Attention to Language Code
The importance of learners' attention to the language code, suggesting that noticing and processing linguistic data are essential for effective language learning
Information Processing
Explores how information is processed in the human mind, discussing the role of memory, attention, and cognitive mechanisms in language learning
Memory and Attention
The significance of working memory and attention in language acquisition, highlighting how these cognitive functions influence the learning and retention of linguistic information
Cognitive Theories
Discusses various cognitive theories related to second language acquisition, including proceduralization, automaticity, and skill acquisition theory
Noticing Hypothesis
Introduces the Noticing Hypothesis, which suggests learners need to consciously notice and register new linguistic elements to learn them effectively
Emergentism
Touches upon emergentist perspectives in second language acquisition, which propose that language learning emerges from complex interactions between cognitive, social, and environmental factors
Language Aptitude
Explores the concept of language aptitude, which refers to the cognitive abilities that influence language learning
Age and Aptitude
Examines the relationship between age and language aptitude, highlighting how different cognitive abilities impact language learning at different stages of life
Implicit vs. Explicit Learning
Discusses the role of implicit and explicit learning processes in language aptitude, emphasizing how learners with varying aptitudes may approach language learning differently
Motivational Theories
Explores different motivational theories in language learning, including integrativeness and self-determination theory
Dynamic Motivation
Emphasizes the dynamic nature of motivation, highlighting how external factors, time, context, and behavior can impact learners' motivation levels
L2 Motivational Self System
Introduces the L2 Motivational Self System, which emphasizes the role of learners' ideal L2-speaking selves in shaping motivation and language learning goals
Personality and Learning Styles
Discusses how personality traits and learning styles influence language learning outcomes
Anxiety and Willingness to Communicate
Delves into the role of foreign language anxiety and willingness to communicate in language learning
Self-Regulation Theory
Introduces self-regulation theory as a framework for understanding how learners regulate their learning behaviors and emotions in the language learning process
