Introspectionism

Explanation:

In 1901 Carl Marbe, by documenting an example of the cognitive unconscious in action, set in motion a debate that would soon result in the rejection of introspectionism.

In 1901, a student of Wundt discovered what he called imageless thought. Karl Marbe asked trained introspectionist to introspect while they compared two object of different weights, holding one in each hand, they could clearly describe their experiences of each weight and which one was heavier, but they could not describe the mental process of judging which one was heavier, this makes him called the experiment imageless thought which is refereed to today as the cognitive unconscious; the processing of perception, memory, learning, thought and language without being aware of it.this is a thinking that occurs without the aid of images or sensory content.His test set in motion a debate that would later on result in the rejection of introspction.

Wikipedia explain Introspection as the examination of one's conscious thoughts and feeling.In psychology, the process of introspection relies exclusively on observation of one's mental state, while in a spiritual context it may refer to the examination of one's soul.someone who is introspective spends considerable time examine his own thoughts and feelings which involves systematic analysis of the individual own mental experience in order to identify its element.example is when you mediate to try to understand your feelings. It was Wilhlem Wundt who popularized introspection.
