Analyse and write up SPSS results and graphs (EEG data)

I have a Masters Research Project and need some help with the data analysis. I have an SPSS file with 34 participants and their mean ERP processed data. The experiment looks at three ERP responses to different anxiety cues. I need help choosing, running and analysing data to compare the ERP responses of high anxious and low anxious individuals at three different stages of threat-processing. I have an idea but am not sure it is correct.

Thank you

The project looks at three stages of threat processing (attention, interpretation and reappraisal) and the three specific ERPs (P2, P3, P600) are hypothesised to be associated with each stage. The data is split into high and low anxious groups (N=17). It uses a new threat processing game called The Bomb. I have some hypotheses but these are vague and can be changed according to the statistical analyses carried out...

Hypothesis 1: Examining the construct validity of The Bomb:

a. youth/parent reported anxiety will be positively correlated with P2 amplitude for ambiguous potential threat (red cue);

b. youth/parent reported anxiety will be negatively correlated with P3 amplitude for actual threat;

c. youth/parent reported anxiety will be negatively correlated with P600 amplitude for threat to others;

d. youth/parent reported anxiety will be positively correlated with BOMB anxiety ratings.

Hypothesis 2: Examining high and low anxious group differences?

a- the high anxious group will show a higher P2 than the low anxious group for red cue

b- the high anxious group will show a lower P3 than low anxious group for threat cue

c- the high anxious group will show lower P3 than low anxious group for threat to others

Hypothesis 3: Threat processes as a cascade:

a. P2 amplitude for ambiguous potential threat (vigilance) will negatively predict P600 amplitude for indirect threat reappraisal, covarying the P3 amplitude for actual threat (detection).

Hypothesis 4: Anxiety moderation of the threat processing cascade:

a. youth/parent reported anxiety will moderate the relationship between P2 amplitude for ambiguous potential threat (vigilance) and P600 amplitude for indirect threat reappraisal.

b. youth/parent reported anxiety will moderate the relationship between P3 amplitude for actual threat (detection) and P600 amplitude for indirect threat reappraisal.

I have written the Introduction for my thesis so I can send that too...
