| Relational self-reference processing advantage is a phenomenon in which the relational self facilitates memory information processing dominance,which is similar to the memory advantage of self-information processing.Research results from cognitive neuroscience suggest that this memory advantage is caused by the sharing mechanism of self and others representation in cognitive processing.Relational self-reference processing and self-reference processing have greater shared neural representation in cognitive mechanism.The theory of specificity holds that self-representation and other representation are relatively independent,each has its own specific representation structure and way.Individuals may have differences in the process of self-information processing in relation to others,rather than similar,unified and indistinguishable.Such differences are reflected in different attachment relationships and attachment patterns.Attachment traits are the concrete embodiment of attachment differentiation,which refers to the sum of a series of traits in all attachment relationships that can stimulate and promote individuals’ motivation and behavior to produce positive attachment relationships.Attachment trait is a form of externalization and specific performance of attachment representation,which has diversity and specificity.Attachment representation attached to multiple work model is put forward,attachment mental representation is not only the most basic characteristic of self-others characterization,but also corresponds to the specific the attachment relationship between characterization,distribution on the different levels of work attachment model,with a particular relationship field particularity.Attachment trait is the core self-concept and self-knowledge of relational self.This domain particularity is not only reflected in the representation of attachment,but also affects the encoding,retrieval,storage and extraction of information through relational self-reference processing.Therefore,it may show the difference of different processing advantages in the process of relational self-reference.This is enlightening significance for expanding the research content of relational self-schema theory and further enriching and improving the research content and memory mechanism of relational self-reference processing advantage.From the perspective of attachment traits,this study explored the characteristics of different memory processing stages of relational self-reference processing advantages and the neural mechanisms of these processing advantages.Since secure attachment priming has a positive effect on memory processing,this study further explored the positive effect of secure attachment priming on relational self-reference processing advantage and the potential neural mechanism.Based on the understanding of the internal working model of attachment theory,Study 1 standardized the lexicon of the basic trait dimensions of adult attachment.On this basis,we investigated the characteristic differences of attachment traits in the level of perception of attachment objects,and found that autonomy traits and warmth traits had different perceptual precedence.Study 3 further proved that the two basic dimensions of attachment traits were significantly correlated with relational self-constructs,and positive autonomy and positive warmth traits were significantly positively correlated with relational self-constructs,while negative autonomy and negative warmth traits were significantly negatively correlated with relational self-constructs,and attachment traits can significantly predict 27%variation in the level of relational self-construct.Research two attachment character feature extraction in the relational self-reference processing advantages,experiment 4 experimental design using the mixture of 2×2×2,compare the parent-child relationship and feature extraction of romantic relationships,found in the parent-child relationship memories of warm word number is significantly higher than the independent word,but is opposite in romantic relationships.The number of recall items in the trait of autonomy was significantly higher than that in the parent-child relationship.Experiment 5 by 3×2×2 mixed design of experiment,further select the attachment type as an object of comparison check attachment type influence on attachment feature extraction advantages,compared with the insecure attachment,security attached to individual under the condition of relational self-reference extract more attachment idiosyncratic words,specifically attachment anxiety individuals weaken the recall the number of warm words.Attachment avoidance individuals weakened the number of independent words and warm words recalled items.The relationship type and attachment type affect the attachment trait terms in the individual retrieval.Attachment trait is specific in the relational self-reference processing advantage,which does not always show the similar relational self-reference processing advantage,but reflects the attachment trait’s feature extraction difference in the memory processing.The relationship type affected the dimension of the advantage of attachment trait extraction,while the attachment type affected the size of the advantage of attachment trait extraction.In order to further explore the neural mechanism of attachment quality difference,the experiment 6 the resting state technology attachment anxiety and attachment avoidance are discussed on the spontaneous neural mechanism of brain activity,the results showed that the significant differences in the low frequency oscillation and the functional connection,after the attachment anxiety scores and cingulate(PCC)of low frequency oscillation(ALFF)significant positive correlation,Moreover,the scores of attachment anxiety were positively correlated with the functional connectivity values of PCC and FFA.Attachment avoidance scores and bilateral tongue back,on the right side of the back after the significant positive correlation,but with both sides of the orbitofrontal cortex and the left temporal gyrus ALFF value is significantly negative correlation,attachment avoidance need more brain regions together at the same time,with the left temporal gyrus and right temporal gyrus,bilateral medial orbitofrontal cortex,and bilateral frontal gyrus,inferior frontal gyrus,temporal back in,next to the hippocampus and the insula,wedge leaf area.The functional connections between the right posterior central gyrus and the inferior temporal gyrus,the inferior parietal lobule,the inferior frontal gyrus and the cuneus were significantly positively correlated.The differences in the neural mechanisms provided a neural basis for explaining the information processing differences between attachment anxiety and attachment avoidance.Attachment characteristics of information processing not only affected by the type of attachment,also will be affected by situational attachments,safety attachment priming effect(SAP)will activate the individual safe and warm memories,experiment 7 is for 5 relations self-reference processing advantage phenomenon,weakened by insecure attachment paradigm of learning-recognition experiment.A 2×2×2 three-factor mixed design was used to investigate the effect of SAP on the memory enhancement of the relational self-reference processing advantage of individuals with different attachment types.The results showed that SAP effect had a more significant effect on the memory enhancement of the feature extraction advantage of individuals with attachment avoidance than that of individuals with secure attachment.The results showed that the attachment avoidance individuals showed a greater advantage in memory retrieval than the secure attachment individuals in the process of relational self-reference,and activated the accessory motor areas,superior temporal gyrus and inferior frontal gyrus.The enhanced activation of the accessory motor areas was a prominent indicator to prove the positive effect of SAP in attachment avoidance individuals.The processing advantage of relational self-reference is influenced by intimacy,and attachment traits have different effects on promoting relationship closeness.The dimensions and levels of attachment traits reflect different emotional memory arousal,and may show different degree of connection with relational self.The third focus of the study was to examine the degree of association between relational self and attachment traits from the perspective of trait judgment advantage.The warmth trait has the social function of facilitating individuals to integrate into social relationships and enhance their intimate experience,and it is easier to arouse individuals’ warm memories related to attachment.Therefore,in the process of trait evaluation of relational self-reference,they may have greater emotional memory arousal,and the more likely they are to get greater attention and cognitive processing of relational self.In Experiment 8,a 2×2 in-subject design was used to examine the evaluative advantage of attachment traits in the process of relational self-reference processing.The results showed that the warmth trait had a greater evaluative advantage in the process of relational self-reference processing.Experiment 9 adopt situational experiments respectively investigate the warm character and autonomy level character on the relationship between the influence of self-reference valuation process,USES the 2×2 subjects in experimental design,the results showed that warm to adjust the relationship between the size of the advantages of self-reference effect,under the condition of relational self-reference,significantly higher than the score of warm high qualities of the low quality.And the evaluation response time is shorter.However,the moderating effect of trait level did not exist in the different relationship contexts of autonomous traits.The study again demonstrated the unique role of warmth in the process of relational self-referential evaluation.Meanwhile,the positive effect of SAP effect also appeared in the memory processing of trait judgment advantage.Experiment 10 used priming grouping to examine the positive effect of SAP effect on the processing of relational self-trait evaluation and the size of the effect.A 2×2×2 repeated measure analysis of variance(ANOVA)was used for behavioral data,and the relational self-evaluation score change index(SCCI)was used as the dependent variable.The results showed that the SCCI scores of the secure attachment priming group were significantly higher than that of the neutral priming group under the condition of relational self-reference.The ALFF value of resting state was used as the brain data index to analyze the influence of different primes on the resting pretest and post-test of individuals.The results showed that the interaction effect between primes and ALFF value of brain region was significant.The ALFF value of right middle frontal gyrus and left inferior temporal gyrus in the safe primes group was significantly higher than that in the neutral primes group.On functional connection in the right frontal gyrus and vermis,wedge leaves are connected and hippocampal function,left superior temporal gyrus and the loop body,the shell and the caudate nuclei exist positive connection,SAP effects promoted individual judgment and evaluation score on the attachment traits,and temporal gyrus and the caudate nucleus function connection enhancement for SAP effect of the positive role of neurological evidence directly.Experiment 11 is examining the effects of SAP based on task for relational self-reference qualities evaluation advantage,the influence of the 2×2×2 repetitive measure analysis of variance,the results found that SAP effect to promote the individual response to the evaluation of warm nature,to evaluate the relationship between self warm and shorter reaction time,the greater the degree of the activation of the medial prefrontal cortex.The medial prefrontal lobe is considered to be the core brain region of self-reference processing.SAP effect promotes the evaluation of the warmth trait of relational self,and the activation degree of medial prefrontal lobe is significantly positively correlated with this score,indicating that SAP effect promotes the self-correlation degree between relational self and warmth trait.Based on the above studies,the main conclusions of this study are as follows:1.Attachment traits can be divided into two basic dimensions:warmth traits and autonomy traits,which affect individuals’ cognition and level of relational self-concept.2.There was an interactive effect between attachment trait valency and dimension on relational self-cognition.In the positive valence,individuals’ evaluation of relational self-autonomy traits was significantly higher than that of warm traits,but in the negative valency,it was the opposite.3.Attachment traits have specific advantages in relational self-reference feature extraction.Parent-child relational schema promotes the individual’s advantage in memory extraction of warmth traits,and secure attachment schema has greater advantages in attachment feature extraction than non-secure attachment schema.4.The specific role of attachment traits in the evaluation of relational self-reference processing.The warm trait has a greater trait judgment advantage than the autonomy trait,and the low warmth trait weakens the trait judgment advantage of relational self-reference,while the autonomy trait level has no significant role in the self-reference processing advantage.5.Secure attachment priming effect(SAP effect)plays a role in memory enhancement in the relational self-reference processing advantage,and the enhanced activation of auxiliary motor area is a prominent symbol of this enhancement effect.However,the positive effect of SAP effect was moderated by attachment type,and the memory enhancement effect of SAP effect was more significant in attachment avoidance individuals,which provided evidence for the specific mechanism of SAP effect in attachment duality characteristics.6.SAP effect on quality judgment advantage of memory enhancement effect is mainly reflected in the positive evaluation of warm nature and self correlation degree,the SAP effects directly promote the individual processing depth and actively evaluating price of attachment quality under the condition of resting safe launch group of left temporal gyrus changes connected with the function of the caudate nucleus values significantly greater neutral start group,The results showed that SAP effect promoted the approach and reward effects of attachment memory representation.Meanwhile,in trait evaluation task,individuals’affirmation of relationship self-warmth trait promoted the greater activation of medial prefrontal lobe,which indicated that SAP effect promoted the degree of conceptual association between relationship self-warmth trait and relationship self-warmth trait.This provides a neural basis for the memory enhancement effect of SAP effect in trait judgment and feature extraction.This study complements the schema theory of relational self-reference processing advantage,verifies the unique role of attachment traits in relational self-reference processing advantage,and provides an empirical basis for the specificity of relational self-reference processing advantage.At the same time,it enriches the cognition of the essential characteristics of attachment in the field of social cognition and expands the cognition of the basic dimensions of social cognition.The attachment trait dimensions established in this paper are consistent with the description and cognition of attachment in the model of social cognition.At the same time,we also verified the memory enhancement effect of SAP effect on relational self-reference processing advantage,and expanded the memory and neural mechanism of relational self-reference processing advantage.This research breakthroughs in research idea from the view point of self-others characterization of the self-others the overlap and sharing mechanism of information processing,but from the view point of self-others distinguish between relational self-reference processing advantages specific mechanism of action,and the system from the Angle of the processing stages,attachment characteristics in order to develop the relationship between self-reference processing specific system research.This study verified the different effects of attachment traits on the advantages of feature extraction and feature judgment,as well as the positive effects of SAP effect on this advantage and the conditional constraints. |
