For that purpose, we adapted to touch two paradigms widely employed in vision. In Experiment 1, we used an experimental phenomenological task consisting of rating the strength of grouping in both acting alone and conjoined cooperative and competitive conditions. In Experiment 2, participants performed a psychophysical task in which an objective (in)correct response was defined by selectively attending to one grouping cue in different blocks of trials. The results showed that spatial proximity dominated over texture similarity when the two principles were conjoined in competition. In addition, the present results are compatible with an additive model of grouping effects as indicated by the greater grouping effect in the cooperative condition and the smaller grouping effect in the competitive condition relative to a.0cting alone grouping principles. The similarities and differences between vision and touch are discussed.eninfo:eu-repo/semantics/openAccess61 Psicologíaartículocooperationcompetitionperceptual groupingspatial proximitytexture-similaritytouchhaptic
