Human Factors
We were on a heading; level at 4000 ft. to intercept the final for RNAV Y XX into ZZZ; we were cleared for the approach. We suddenly received a terrain terrain pull up. We proceeded to pull up even though we were visual and there was no terrain that we were going to impact. We also received a stick shaker as we pulled up doing 210 kts. not configured. As we pulled up the terrain warning went away around 4400 ft. and we also pushed down slightly because of the shaker; which also went away. I believe we did everything correctly; I am not exactly sure why we received that warning.
EMB-145 Captain reported getting a terrain alert and stick shaker while intercepting the approach. The flight crew responded to both; which eventually dissipated.
