Answer:
a limited sense of self-effeciency
Explanation:
Self efficacy cannbe described as a person's judgement about whether he or she can do something. It is an estimation of one's ability relative to a task or tasks he can perform.
This is further believed to be confidence in one's ability to produce the type of outcomes one desires.
It is expressly portrayed by Bandura's social learning theory. The theory is based on thoughts & feelings of confidence, the confidence talked about is not general confidence, here confidence level varies from task to task.
Self-efficacy is the belief we have in our own abilities, specifically our ability to meet the challenges ahead of us and complete a task successfully .
Bertram having personal doubt in his ability to complete a task reflects a case of one who has limited sense or belief of self efficacy or efficiency.
