Learning a language is difficult. As a language teacher and multilingual, I am all too familiar with the fear, frustration, insecurity, and cultural barriers. Yet, on the other side of the coin, there is pride, achievement, joy, connection, and belonging. The inevitable ups and downs are inherent in any journey towards mastery. There are tons of grammar books, numerous language learning apps, and several teaching methodologies; but not enough attention is being paid to the psychology of language learning. In his book The Inner Game of Tennis, Timothy Gallwey writes about the importance of beginners and advanced players alike to focus on the psychological aspects of the sport. He makes a distinction between technical prowess, which he calls the outer game, and psychological fortitude, the inner game. In language learning, the outer game is the knowledge of the language and culture – grammar, punctuation, vocabulary, social norms, social expectations, gestures, eye contact, conversational style, and so forth. The inner game is concerned with confidence, beliefs, identity, emotions, self-knowledge, and resilience. It is crucial to focus on both parts – the outer and inner game – to facilitate learning. One is not better than the other.The psychology of language learning encompasses several different but interrelated elements. It is multifaceted and impossible to capture completely in a model. Each component should be maximized or minimized to help learners achieve their language potential. What this model tries to achieve is not completeness but usefulness.
