This research study investigates the cognitive, psychological and personal factors affecting the accuracy and fluency of English language usage among Arab learners. Early research led by Chomsky (1965) and Krashen (1981) suggested that an individual’s Language Acquisition Device once triggered at the appropriate time and supported with adequate Comprehensible Input can lead to automatic development of an L2. Relevant research suggests that children are born with the instinct or innate facility for language acquisition provided they have no physical or mental impairment (Al Ghazali, 2006). However, past research (Engin and Seven, 2014; Hanani, 2009; Gupta, 2008; Latu, 1994) has led to the identification of additional factors that go beyond the cognitive domain. These factors were examined individually and against a background of teaching methods, phonetics application, and classroom conditions. In this research, a mixed research study was designed in which a survey and interviews were conducted with a number of university students. With minimal effect from the researcher, the data were collected to examine the influence of these factors on learners’ proficiency of English language and application. The findings reveal that Arab learners’ ability to learn English is dependent on psychological motivation, physical needs to apply it, and personal reasoning
