Document Summary

Average"s (cid:373)easure to o(cid:374)e de(cid:272)i(cid:373)al pla(cid:272)e (cid:894)la(cid:271)(cid:895) When between 50-120ms we see it as 2 stimuli and have to process both. Anything after 120ms, stim 1 has been processed before stim 2 is, therefore there is no bottleneck: this is physiologically based (physiological refractory period), is the delay with the axons, and therefore we cant process a response. Prp in sport: stimulus 1 = fake move. Want opponent to process fake move and organize a response: stimulus 2 = actual move. Capitalize on prp process to delay response to actual move. Heath thinks this is genetic, because you need someone to be able to move very fast to perform these. Attention as a filter: considers attention to be a fixed and undifferentiated capacity, but mediated by. Physiological and psychological level of activation or excitement of the cns varies widely from very low during sleep to very high during threat to self. Want to be able to modulate this for tests.
