zajoncs social facilitation theory predicts that

question 4

susceptibility to biasing influences
high internal validity
lack of explanations
a and b
a and c

Explanation:

Analyze Zajonc's social facilitation theory

Zajonc's social facilitation theory (drive theory) posits that the presence of others increases physiological arousal. This arousal strengthens the emission of the dominant response. For well-learned or simple tasks, the dominant response is typically correct, meaning performance is facilitated (improved) by an audience. For novel, complex, or unlearned tasks, the dominant response is often incorrect, meaning performance is impaired (hindered) by an audience. Therefore, the theory predicts that performance on well-learned tasks is facilitated by an audience.

Analyze limitations of professional practice knowledge

Professional practice knowledge is gained through practical experience rather than systematic scientific research. In sport psychology and kinesiology, its limitations include being highly susceptible to subjective bias (biasing influences) and lacking systematic explanations for why certain interventions work (lack of explanations). High internal validity is a characteristic of tightly controlled scientific experiments, not professional practice knowledge. Therefore, the limitations include both susceptibility to biasing influences and lack of explanations, which corresponds to options "a and c".
