Table 2: Differences between DG and HG participants on TAS-20, BioPLUX physiological parameters and SAM; TAS-20 Total – TAS-20 total score; DIF - difficulties identifying feelings; DDF - difficulties describing feelings; EOT - externally-oriented thinking; SCL Baseline - tonic level of skin conductance measured at the resting period (previous to the set of images) by bioPLUX; HR Baseline - heart rate frequency measured at the resting period (previous to the set of images) by bioPLUX; IRR Baseline - respiratory frequency measured at the resting period (previous to the set of images) by bioPLUX; SRR A+ V+ - skin conductance response rate (events/min.) for high arousing positive stimuli, measured by bioPLUX; SRR A+ V- - skin conductance response rate (events/min.) for high arousing negative stimuli, measured by bioPLUX; SRR A- V+ - skin conductance response rate (events/min.) for low arousing positive stimuli, measured by bioPLUX; SRR A- V- - skin conductance response rate (events/min.) for low arousing negative stimuli, measured by bioPLUX, HR A+ V+ - heart rate for high arousing positive stimuli measured by bioPLUX; HR A+ V- - heart rate for high arousing negative stimuli measured by bioPLUX; HR A- V+ - heart rate for low arousing positive stimuli measured by bioPLUX; HR A- V- - heart rate for low arousing negative stimuli measured by bioPLUX; PHRI A+ V+ - relative heart rate variation between baseline and stimuli (%) for high arousing positive stimuli, measured by bioPLUX; PHRI A+ V- - relative heart rate variation between baseline and stimuli (%) for high arousing negative stimuli, measured by bioPLUX; PHRI A- V+ - relative heart rate variation between baseline and stimuli (%) for low arousing positive stimuli, measured by bioPLUX; PHRI A- V- - relative heart rate variation between baseline and stimuli (%) for low arousing negative stimuli, measured by bioPLUX; SAM Valence A+ V + - the appraisal of valence through Self-Assessment Manikin for high arousing positive stimuli; SAM Valence A+ V- - the appraisal of valence through Self-Assessment Manikin for high arousing negative stimuli; * p < .05 † p < .10
