Here are the variable meanings (taken directly from the script syntax):
D_biep_a 'good+INSECT association 1st blocka'
/ D_biep_b 'good+INSECT association 2nd blocka'
/ Na '# trials, 1st combined blocks'
/ Nb '# trials, 2nd combined blocks'
/ M1a 'Mn Lat. 1st block, pairing 1'
/ M2a 'Mn Lat. 1st block, pairing 2'
/ M1b 'Mn Lat. 2nd block, pairing 1'
/ M2b 'Mn Lat. 2nd block, pairing 2'
/ ERR1a 'Error % 1st block, pairing 1'
/ ERR2a 'Error % 1st block, pairing 2'
/ ERR1b 'Error % 2nd block, pairing 1'
/ ERR2b 'Error % 2ns block, pairing 2'
/ SUBJECT 'Session ID' .
ERR_1 'Error % for Pairing 1 (both combined tasks)'
/ ERR_2 'Error % for Pairing 2 (both combined tasks)' .
D_biep 'good+INSECT association all blocks' .
PCT_300 '% latencies below 300 ms'
/ PCT_400 '% latencies below 400 ms'
/ PCT_10K '% latencies above 10,000 ms'
/ AVELTNCY 'Overall average latency (ms)'
/ ERRORPCT 'Overall % errors'
/ NTRIALS 'Total # of combined-task trials' .
To clarify, the D_biep_a, D_biep_b, and D_biep scores are the d score that measures the association. D_biep is the overall association calculated from both the first and second blocks of each pairing. The labels are in terms of flowers and insects, which are the categories used in the templates, so you should substitute your own categories here.
