The unconscious integration advantage of self-related information:Evidence from the subliminal same-different task paradigm
摘要
Abstract
When processing large volumes of information,only a limited subset can be consciously integrated into new representations,while other critical information must be unconsciously integrated to support survival and environmental adaptation.Previous research suggests that self-related information serves as a"binding glue,"thereby facilitating integration between stimuli with consistent advantages at the perceptual and semantic levels.However,whether or not self-related information can be integrated unconsciously remains unclear.Addressing this issue could deepen understanding of the mechanisms underlying self-related information integration.Accordingly,the current study utilized three experiments to systematically examine the unconscious integration advantage of self-related information,focusing on the integration window size and specific levels of representation at which this advantage occurred. This study adopted the recently developed subliminal same-different task as an effective tool for assessing unconscious integration performance,in conjunction with the self-perceptual matching task(SPMT)to investigate the unconscious integration mechanisms of self-related information.The subliminal same-different task simultaneously presented two primes and two targets,with the congruency effect between the prime-target relationship used to assess unconscious integration.Experiment 1(N=32)examined the congruency effect of neutral geometric shapes across three spatial integration window(SIW)sizes(1.53°,4.02°,6.51°).Experiment 2(N=32)introduced social information(self,friend,none)to explore its influence on the congruency effect,while controlling for stimulus familiarity using SPMT.Experiment 3(N=32)further examined SIW that showed self-related congruency advantages in Experiment 2,dissociating perceptual similarity to examine the effects of social information(self,friend)and integration levels(perceptual representation level,semantic representation level)on the congruency effect. Experiment 1 revealed that neutral shapes exhibited a congruency effect solely at the 1.53° SIW,indicating that low-level unconscious perceptual integration occurs only at this SIW.In Experiment 2,significant congruency effects were observed for all levels of social information at the 1.53° SIW,with no differences among them.At the 4.02° SIW,only self-related shapes presented a significant congruency effect,while no congruency effects were significant at the 6.51° SIW.These findings suggest that the involvement of social information modulates congruency effects over a considerably broad SIW(4.02°),while self-related information specifically exhibits unconscious integration advantages at the 4.02° SIW.Experiment 3 further demonstrated that this advantage effect did not depend on perceptual similarity but can occur at the perceptual and semantic representation levels. In summary,the current study was the first to identify an unconscious integration advantage for self-related information.These findings support the windows of integration(WOI)hypothesis,suggesting that the unconscious integration advantage of self-related information is constrained by the SIW size and can occur at the early perceptual and late conceptual stages of information processing.关键词
