Abstract

Previous work on the direct speed–intensity association (SIA) on comparative judgement tasks involved spatially distributed responses over spatially distributed stimuli with high motivational significance like facial expressions of emotions. This raises the possibility that the inferred stimulus-driven regulation of lateralized motor reactivity described by SIA, which was against the one expected on the basis of a valence-specific lateral bias, was entirely due to attentional capture from motivational significance (beyond numerical cognition). In order to establish the relevance of numerical cognition on the regulation of attentional capture we ran two complementary experiments. These involved the same direct comparison task on stimulus pairs that were fully comparable in terms of their analog representation of intensity but with different representational domain and motivational significance: symbolic magnitudes with low motivational significance in experiment 1 vs. emotions with rather high motivational significance in experiment 2. The results reveal a general SIA and point to a general mechanism regulating comparative judgements. This is based on the way spatial attention is captured toward locations that contain the stimulus which is closest in term of relative intensity to the extremal values of the series, regardless from its representational domain being it symbolic or emotional.

Fantoni et al. (2019) showed in three Experiments how SIA model provided a thoughtful and effective predictor for speed performances in comparative judgement of facial expressions of emotions, when valence was either task relevant (Experiment 1 and 2) or task irrelevant (Experiment 3) and in both presence (Experiment 1 and 3) or absence (Experiment 2) of foveal emotion presentation conditions (Experiment 1, with a direct valence comparison task in presence of foveation: rc = 0.69, 95% CI [0.68, 0.71]; Experiment 2, with a direct valence comparison task in absence of foveation: rc =0 .75, 95% CI [0.73, 0.76]; and in Experiment 3, with an indirect emotion identification task in presence of foveation: rc = 0.73, 95% CI [0.72, 0.75]).

see Fantoni et al. (2019), for details on the procedure of lme fitting. The estimation of the goodness of fit was based on AIC-index, BIC-index, and χ2. The estimates of significance of lme’s fixed effects and parameters were based on Type III F-tests; the estimates of effect size were based on the concordance correlation coefficient rc, and Cohen’s d supporting results of post-hoc tests were performed on lme estimated coefficients, with paired sample t-tests with unequal variance.
