Why do we have mixed findings of personality studies?
1. The major difficulty in investigating personality characteristics is that of identification and
measurement.
2. Another explanation is that personality variables may be a major factor only in the acquisition of
conversational skills, not in the acquisition of literacy or academic skills.
• The confusion might be due to the fact that comparisons are made between studies that measure
communicative ability and studies that measure grammatical accuracy or metalinguistic
knowledge.
• Personality variables seem to be consistently related to the former, but not to the latter.
