Answer:
Dr. Joan Nideffer, a sports psychologist, proposed four dimensions of attention in her model. Two of the internal dimensions of attention in Nideffer's model are:
1. **Broad-Internal Focus:** This refers to the athlete's ability to maintain concentration on relevant internal cues, such as their thoughts, bodily sensations, or emotions. It involves staying attuned to one's own mental and physical state during performance.
2. **Narrow-Internal Focus:** This dimension involves focusing on a specific internal cue, often a thought or sensation related to the task at hand. It's a more pinpointed form of internal attention and can be useful for fine-tuning performance.
The other two dimensions in Nideffer's model are External Focus, which includes Broad-External Focus (awareness of the external environment) and Narrow-External Focus (focusing on specific external cues or objects). These dimensions help athletes and individuals in various fields understand and improve their attentional processes during activities.
