Final answer:
Training in Emotional Intelligence can improve both the actual ability and self-perceived ability in emotional competencies, supporting the answer that both can improve with training.
Step-by-step explanation:
In the context of Emotional Intelligence testing, training in EI prior to taking tests can impact both a person's ability and their self-perceived ability to appraise and express emotions accurately. Research suggests that structured training programs can improve individuals' skills in emotional awareness, regulation, and management. Such improvements can enhance their self-perceived ability by boosting confidence in handling emotional tasks. Therefore, training can have the dual benefit of enhancing actual Emotional Intelligence competencies as well as the individual's perception of their abilities, making the correct answer 'a) Training improves both ability and self-perceived ability'.
