I have to analyse data from a transverse vs. non-transverse patterning learning experiment, structured in two parts. All participants have taken part in both parts, so it is only a within-participants study (1. part non-transverse patterning and then immediately 2. part transverse patterning). Each part was structured in 3 phases in which the participant had to identify the "correct" symbol in a presented pair (1. phase AB, 2. phase BC, 3. phase AC and 1. phase AB, 2. phase BC, 3. phase CA resp). The participant (starting with phase 1) had to identify 14 correct pairs in a row to enter the next phase. My hypos so far:

Null Hypothesis (H0): Number of trial attempts for TP task will not significantly increase over NTP task.

Alternative Hypothesis (H1): Number of trial attempts for TP task will significantly increase over NTP task.

What kind of SPSS analyses would you recommend? Tbh I am not quite sure what exactly my independent variable is and how many there are. Is it only one IV, that is "learning or condition" with 2 levels (TP and NTP), or are TP and NTP two IVs? And how do I involve the 3 different phases in each part?

I guess my dependent variable is the number of attempts each participant needed.

I would be really thankful if someone can give me some advice!
