Zimbabwe are winless in the five-match series so far, losing the first three ODIs without giving much of a headache to the visitors.
"I think (the problem is) mental toughness. I don't think we're mentally sharp enough. We're just not making the precise decisions at the right time and not putting a real price on our wickets. Too many soft dismissals," Taylor said.
"The most difficult one for me was the second game when we had an opportunity to win that game, and we dropped Dhawan and we dropped plenty of chances and allowed them to get to 290.
Taylor said dealing with Indian bowlers might be tough but not impossible and a bit of patience was all that his batsmen needed to have.
"We all know in the mornings it's a little tricky (to bat) but technically we haven't been good enough. The Indian bowlers, they just keep it nice and simple," he explained.
