Effect of action and other verbs upon the height of the SVJ.

<p>Squat Vertical Jumps (J<sub>1</sub> to J<sub>4</sub>, SVJ) were executed, in experiment 1, in the absence of cognitive stimuli; BJ: control jump; experiment 2 was performed to observe the effect of various cognitive stimuli such as KI (kinaesthetic imagery), the pronunciation of the specific action verb <i>jump</i> or its silent pronunciation (S-<i>jump</i>), subjects also performed a mental subtraction (MS, three digits minus two digits, the result was told at the end of the experiment); experiment 3 studied the reading (R) of <i>jump</i> under different modalities: the control was its pronunciation as in the precedent experiments, <i>R</i>: the subjects were asked to read loudly or silently (RS) the verb written on a screen, in Rm the verb was read loudly while moving bottom-up on the screen (moderate speed on Power Point software), (RSm) idem as in Rm, but the reading was silently performed, as control (<i>blank screen</i>) the subjects were asked to jump in front of the white (not lighted) screen; the effect of other action verbs (<i>lick, pinch</i> and <i>tiáo</i>) was studied in experiment 4; hearing action verbs (H) was studied in experiment 5 where subjects heard the same action verbs that in experiment 4 (H-<i>lick, H-pinch</i> and H-<i>tiáo</i>), through the voice of an experimenter, and in experiment 7 (H-<i>jump</i>, H-<i>fall</i> and H-<i>stop</i>). In experiment 6, the effect of the pronunciation of other non specific verbs upon the SJV height was realised with verbs <i>jump</i> (used as control), <i>win</i>, <i>lose</i>, <i>move</i> and <i>dream</i>. In all experiments the cognitive stimuli were randomized. The data are expressed as cm ± standard deviation (SD) and probability p and the z-score.</p>
