Abstract
The present study was an attempt to investigate the impact of Neuoro-Linguistic Programming (NLP) on EFL learners’ vocabulary achievement. To fulfill the purpose of this study, a group of 90 female EFL learners at Parsayan Language Institute, Tehran, Iran, were selected and 60 of them were selected based on convenient non-random sampling then a PET was administered to homogenize their level of proficiency at intermediate level. After homogenizing the sample was divided into two groups as control and experimental with 30 learners in each. Then, all of the participants in both groups took a vocabulary test as a pre-test. With a treatment process of 12 sessions, in the experimental group the teacher taught the vocabularies of the book based on swish pattern as one of neuro linguistic programming techniques. In the control group, vocabularies were taught with dictionary, synonyms and antonyms to understand the meaning of words from passages. On the thirteenth session, the participants of both groups took the vocabulary post-test to measure their achievement of vocabularies. To analyze the data, ANCOVA was run and the results showed that the experimental group outperformed the control group in vocabulary post-test. In other words, neuro linguistic programming had significant impact on EFL learners’ vocabulary achievement.
