Exploring the effects of ownership and choice on self-memory biases

Objects encoded in the context of temporary ownership by self enjoy a memorial advantage over objects owned by other people. This memory effect has been linked to self-referential encoding processes. The current inquiry explored the extent to which the effects of ownership are influenced by the degree of personal choice involved in assigning ownership. In three experiments pairs of participants chose objects to keep for ownership by self, and rejected objects that were given to the other participant to own. Recognition memory for the objects was then assessed. Experiment 1 showed that participants recognised more items encoded as "self-owned" than "other-owned", but only when they had been chosen by self. Experiment 2 replicated this pattern when participants' sense of choice was illusory. A source memory test in Experiment 3 showed that self-chosen items were most likely to be correctly attributed to ownership by self. These findings are discussed with reference to the link between owned objects and the self, and the routes through which self-referential operations can impact on cognition.     

Source memory that encoding was self-referential: the influence of stimulus characteristics

Decades of research suggest that encoding information with respect to the self improves memory (self-reference effect, SRE) for items (item SRE). The current study focused on how processing information in reference to the self affects source memory for whether an item was self-referentially processed (a source SRE). Participants self-referentially or non-self-referentially encoded words (Experiment 1) or pictures (Experiment 2) that varied in valence (positive, negative, neutral). Relative to non-self-referential processing, self-referential processing enhanced item recognition for all stimulus types (an item SRE), but it only enhanced source memory for positive words (a source SRE). In fact, source memory for negative and neutral pictures was worse for items processed self-referentially than non-self-referentially. Together, the results suggest that item SRE and source SRE (e.g., remembering an item was encoded self-referentially) are not necessarily the same across stimulus types (e.g., words, pictures; positive, negative). While an item SRE may depend on the overall likelihood the item generates any association, the enhancing effects of self-referential processing on source memory for self-referential encoding may depend on how embedded a stimulus becomes in one’s self-schema, and that depends, in part, on the stimulus’ valence and format. Self-relevance ratings during encoding provide converging evidence for this interpretation.     

Parallels in Preschoolers' and Adults' Judgments About Ownership Rights and Bodily Rights

Understanding ownership rights is necessary for socially appropriate behavior. We provide evidence that preschoolers' and adults' judgments of ownership rights are related to their judgments of bodily rights. Four‐year‐olds (n = 70) and adults (n = 89) evaluated the acceptability of harmless actions targeting owned property and body parts. At both ages, evaluations did not vary for owned property or body parts. Instead, evaluations were influenced by two other manipulations—whether the target belonged to the agent or another person, and whether that other person approved of the action. Moreover, these manipulations influenced judgments for owned objects and body parts in the same way: When the other person approved of the action, participants' judgments were positive regardless of who the target belonged to. In contrast, when that person disapproved, judgments depended on who the target belonged to. These findings show that young children grasp the importance of approval or consent for ownership rights and bodily rights, and likewise suggest that people's notions of ownership rights are related to their appreciation of bodily rights.     

记忆的自我参照效应

自我参照效应(self-reference effect)指的是记忆材料与自我相联系时的记忆效果显著优于其他编码条件。自我对记忆的促进作用,存在多种理论解释,最主要的有:精细加工说,组织加工说以及双过程说。自我参照效应的研究为应用脑功能成像技术对自我进行脑定位提供了一个新的视角,为情节记忆的HERA模型提供了有力的证据。目前,自我参照效应的研究同文化差异研究相结合,成为一个新的研究趋势。     

Autobiographical memories and views of the future: In relation to dysphoria

The present study investigated dysphoric individuals' self‐referential processing of autobiographical memories and future personal events, in relation to specificity and response latency. Dysphoric individuals (n  =  17) and nondysphoric controls (n  =  17) were selected from a larger sample based on self‐reported depression. Participants completed an autobiographical memory task (AMT) and a future event task (FET), using pleasant and unpleasant (anxiety‐relevant, depression‐relevant) emotional word cues. In response to each emotional cue, participants were required to access and write down a specific personal memory and future event, respectively. Consistent with the hypotheses, dysphoric individuals were less specific in describing pleasant and unpleasant experiences (particularly pleasant), irrespective of time condition. As expected, dysphoric individuals' specificity for distinct depression‐relevant and anxiety‐relevant experiences did not differ significantly. As predicted, all participants were less specific in describing future personal events than in recalling personal memories. As predicted, dysphoric individuals took longer to think of pleasant memories and pleasant future experiences than controls but, as expected, groups did not differ significantly on mean reaction times for past and future unpleasant experiences. Overall, the data showed a degree of consistency in participants' past and future‐oriented processing of self‐referential material. Although considerable research has investigated autobiographical memories in relation to emotional disturbance, the present findings suggest that constructing future emotional experiences is also an important aspect of mental health.     

Yours or mine? Ownership and memory

An important function of the self is to identify external objects that are potentially personally relevant. We suggest that such objects may be identified through mere ownership. Extant research suggests that encoding information in a self-relevant context enhances memory (the so-called 'self-reference effect'), thus an experiment was designed to test the impact of ownership on memory performance. Participants either moved or observed the movement of picture cards into two baskets; one of which belonged to self and one which belonged to another participant. A subsequent recognition test revealed that there was a significant memory advantage for objects that were owned by self. Acting on items (i.e., moving them) had no impact on memory. Results are discussed with reference to the importance of self-object associations in cognition.     

The development of bodily self‐consciousness: changing responses to the Full Body Illusion in childhood

The present work investigates the development of bodily self‐consciousness and its relation to multisensory bodily information, by measuring for the first time the development of responses to the full body illusion in childhood. We tested three age groups of children: 6‐ to 7‐year‐olds (n = 28); 8‐ to 9‐year‐olds (n = 21); 10‐ to 11‐year‐olds (n = 19), and a group of adults (n = 31). Each participant wore a head‐mounted display (HMD) which displayed a view from a video camera positioned 2 metres behind their own back. Thus, they could view a virtual body from behind. We manipulated visuo‐tactile synchrony by showing the participants a view of their virtual back being stroked with a stick at the same time and same place as their real back (synchronous condition), or at different times and places (asynchronous condition). After each period of stroking, we measured three aspects of bodily self‐consciousness: drift in perceived self‐location, self‐identification with the virtual body, and touch referral to the virtual body. Results show that self‐identification with the virtual body was significantly stronger in the synchronous condition than in the asynchronous condition even in the youngest group tested; however, the size of this effect increased with age. Touch referral to the virtual body was greater in the synchronous condition than in the asynchronous condition only for 10‐ to 11‐year‐olds and adults. Drift in perceived self‐location was greater in the synchronous condition than in the asynchronous condition only for adults. Thus, the youngest age tested can self‐identify with a virtual body, but the links between multisensory signals and bodily self‐consciousness develop significantly across childhood. This suggests a long period of development of the bodily self and exciting potential for the use of virtual reality technologies with children.     

“Because It's Hers”: When Preschoolers Use Ownership in Their Explanations

Young children show competence in reasoning about how ownership affects object use. In the present experiments, we investigate how influential ownership is for young children by examining their explanations. In three experiments, we asked 3‐ to 5‐year‐olds (N = 323) to explain why it was acceptable (Experiments 1–3) or unacceptable (Experiment 2 and 3) for a person to use an object. In Experiments 1 and 2, older preschoolers referenced ownership more than alternative considerations when explaining why it was acceptable or unacceptable for a person to use an object, even though ownership was not mentioned to them. In Experiment 3, ownership was mentioned to children. Here, younger preschoolers frequently referenced ownership when explaining unacceptability of using an object, but not when explaining why using it was acceptable. These findings suggest that ownership is influential in preschoolers' explanations about the acceptability of using objects, but that the scope of its influence increases with age.     

Young children's beliefs about self‐disclosure of performance failure and success

Self‐disclosure of performance information involves the balancing of instrumental, learning benefits (e.g., obtaining help) against social costs (e.g., diminished reputation). Little is known about young children's beliefs about performance self‐disclosure. The present research investigates preschool‐ and early school‐age children's expectations of self‐disclosure in different contexts. In two experiments, 3‐ to 7‐year‐old children (total N = 252) heard vignettes about characters who succeeded or failed at solving a puzzle. Both experiments showed that children across all ages reasoned that people are more likely to self‐disclose positive than negative performances, and Experiment 2 showed that children across all ages reasoned that people are more likely to self‐disclose both positive and negative performances in a supportive than an unsupportive peer environment. Additionally, both experiments revealed changes with age – Younger children were less likely to expect people to withhold their performance information (of both failures and successes) than older children. These findings point to the preschool ages as a crucial beginning to children's developing recognition of people's reluctance to share performance information.     

Doing Despite Disliking: Self‐regulatory Strategies in Everyday Aversive Activities

We investigated the self‐regulatory strategies people spontaneously use in their everyday lives to regulate their persistence during aversive activities. In pilot studies (pooled N = 794), we identified self‐regulatory strategies from self‐reports and generated hypotheses about individual differences in trait self‐control predicting their use. Next, deploying ambulatory assessment (N = 264, 1940 reports of aversive/challenging activities), we investigated predictors of the strategies' self‐reported use and effectiveness (trait self‐control and demand types). The popularity of strategies varied across demands. In addition, people higher in trait self‐control were more likely to focus on the positive consequences of a given activity, set goals, and use emotion regulation. Focusing on positive consequences, focusing on negative consequences (of not performing the activity), thinking of the near finish, and emotion regulation increased perceived self‐regulatory success across demands, whereas distracting oneself from the aversive activity decreased it. None of these strategies, however, accounted for the beneficial effects of trait self‐control on perceived self‐regulatory success. Hence, trait self‐control and strategy use appear to represent separate routes to good self‐regulation. By considering trait‐ and process‐approaches these findings promote a more comprehensive understanding of self‐regulatory success and failure during people's daily attempts to regulate their persistence. © 2018 European Association of Personality Psychology     

What would Batman do? Self‐distancing improves executive function in young children

This experimental research assessed the influence of graded levels of self‐distancing – psychological distancing from one's egocentric perspective – on executive function (EF) in young children. Three‐ (n = 48) and 5‐year‐old (n = 48) children were randomly assigned to one of four manipulations of distance from the self (from proximal to distal: self‐immersed, control, third person, and exemplar) on a comprehensive measure of EF. Performance increased as a function of self‐distancing across age groups. Follow‐up analyses indicated that 5‐year‐olds were driving this effect. They showed significant improvements in EF with increased distance from the self, outperforming controls both when taking a third person perspective on the self and when taking the perspective of an exemplar other (e.g., Batman) through role play. Three‐year‐olds, however, did not show increased EF performance as a function of greater distance from the self. Preliminary results suggest that developments in theory of mind might contribute to these age‐related differences in efficacy. These findings speak to the importance of psychological distancing in the expression of conscious control over thought and action from a young age and suggest a promising new avenue for early EF intervention.     

You were always on my mind: The importance of “significant others” in the attenuation of retrieval‐induced forgetting in Japan

Research on memory has demonstrated that remembering material can cause forgetting of related information, which is known as retrieval‐induced forgetting (RIF). Macrae and Roseveare identified “self” as one of the boundary conditions of this effect in the Western cultural context, showing that RIF was eliminated when material was encoded to be related to the self (known as self‐referential effect), but not to significant others. In this study, we predicted and found that significant others could be another boundary condition in Japanese cultural contexts in which self and agency are more interdependent or conjoint; RIF was observed neither under best‐friend‐related encoding nor under family‐related encoding in Japan. The effect of significant others is found uniquely in Japanese cultural contexts, suggesting that the cultural model of self has significant power in the spontaneous system of memory.     

Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates

Hintsanen, M., Alatupa, S., Pullmann, H., Hirstiö‐Snellman, P. & Keltikangas‐Järvinen, L. (2010). Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates. Scandinavian Journal of Psychology 51, 488–494. The present study examined the validity of self‐ and teacher‐reported social status and its relations to self‐esteem and temperament in a geographically representative cohort of Finnish adolescents (N = 3941, mean age 15.1 years). High agreement was found between self‐ and teacher‐rated social status (r = 0.42). Different aspects of self‐esteem were differently related to social status. When other temperament and self‐esteem variables were included in the analyses, strongest predictor for self‐rated social status in both genders was social self‐esteem (p < 0.01) and for teacher‐rated social status general self‐esteem (p < 0.01). The strongest temperamental predictors of social status were lower inhibition in girls (p < 0.01, self‐ and teacher‐rated) and higher impulsivity (p < 0.01, self‐rated) and activity (p < 0.01, teacher‐rated) in boys. The present findings are consistent with the view that social functioning and peer relations are associated with individual differences in self‐concept and temperament dimensions.     

Self‐reference and group membership: evidence for a group‐reference effect

Two experiments were designed to explore whether encoding information in reference to a group would facilitate the later recall of that information to the same extent as encoding with reference to the self. In both experiments, participants encoded adjectives with reference to the self, semantic properties, or a group and were subsequently given a surprise‐free recall test. In Experiment 1 (N = 37), the participants' university served as the reference group. In Experiment 2 (N=41), the participants' family served as the reference group. In both experiments, self‐reference resulted in better recall than semantic processing, replicating the typical self‐reference effect (SRE). More importantly, strong evidence for a group‐reference effect (GRE) was found in that group‐reference resulted in better recall than semantic processing and in fact facilitated recall to the same extent as self‐referencing. The existing explanations (schemas, organization, elaboration, mental cueing, and evaluation) for the SRE were compared with regard to their viability in accounting for the GRE patterns. We discuss additional features that may be important in the explanation of the SRE and suggest future directions for research on group‐referencing. Copyright © 2002 John Wiley & Sons, Ltd.     

Older adults show a self-reference effect for narrative information

The self-reference effect (SRE), enhanced memory for information encoded through self-related processing, has been established in younger and older adults using single trait adjective words. We sought to examine the generality of this phenomenon by studying narrative information in these populations. Additionally, we investigated retrieval experience at recognition and whether valence of stimuli influences memory differently in young and older adults. Participants encoded trait adjectives and narratives in self-reference, semantic, or structural processing conditions, followed by tests of recall and recognition. Experiment 1 revealed an SRE for trait adjective recognition and narrative cued recall in both age groups, although the existence of an SRE for narrative recognition was unclear due to ceiling effects. Experiment 2 revealed an SRE on an adapted test of narrative recognition. Self-referential encoding was shown to enhance recollection for both trait adjectives and narrative material in Experiment 1, whereas similar estimates of recollection for self-reference and semantic conditions were found in Experiment 2. Valence effects were inconsistent but generally similar in young and older adults when they were found. Results demonstrate that the self-reference technique extends to narrative information in young and older adults and may provide a valuable intervention tool for those experiencing age-related memory decline.     

When My Object Becomes Me: The Mere Ownership of an Object Elevates Domain‐Specific Self‐Efficacy

Past research on the mere ownership effect has shown that when people own an object, they perceive the owned objects more favorably than the comparable non‐owned objects. The present research extends this idea, showing that when people own an object functional to the self, they perceive an increase in their self‐efficacy. Three studies were conducted to demonstrate this new form of the mere ownership effect. In Study 1, participants reported an increase in their knowledge level by the mere ownership of reading materials (a reading package in Study 1a, and lecture notes in Study 1b). In Study 2, participants reported an increase in their resilience to sleepiness by merely owning a piece of chocolate that purportedly had a sleepiness‐combating function. In Study 3, participants who merely owned a flower essence that is claimed to boost creativity reported having higher creativity efficacy. The findings provided insights on how associations with objects alter one's self‐perception.     

The effects of ageing and divided attention on the self-reference effect in emotional memory: Spontaneous or effortful mnemonic benefits?

The self-reference effect (SRE) is a powerful memory advantage associated with encoding in reference to the self (e.g., Rogers, Kuiper, & Kirker, 1977). To explore whether this mnemonic benefit occurs spontaneously, the current study assessed how ageing and divided attention affect the magnitude of the SRE in emotional memory (i.e., memory for emotional stimuli). The sample included a young Full Attention group (young-FA), a young Divided Attention group (young-DA), and an older adult group. The division of attention was manipulated at encoding where participants incidentally studied positive, negative, and neutral trait adjectives in either a self-reference (i.e., rating how well each word describes themselves) or an other-reference condition (i.e., rating how well each word describes another person). Memory for these words was assessed with both recall and recognition tasks. The results from both tasks demonstrated equivalent SRE for all three groups across emotional valence categories of stimuli, suggesting that the SRE is a spontaneous, effortless, and robust effect in memory.     

大学生记忆的自我与专业参照效应:专业认同的作用

群体参照效应研究证实社会群体身份及内群体认同对记忆的参照加工具有重要作用。以往研究从大学生的多重社会群体身份角度探讨了内群体记忆加工优势,却忽视了其另一重要群体身份划分标准——专业。本研究结合自我和群体参照范式,设置多个参照条件(自我、专业内群体、专业外群体、语义),从专业身份这一新视角考察大学生记忆的自我与专业参照效应以及专业认同的作用,并对比个体自我与群体自我之间的差异。结果发现:(1)参照自我和专业内群体时的记忆成绩优于参照其他编码条件;(2)相比专业参照,自我参照的记忆效果更佳;(3)专业认同度越高,对专业内群体信息记忆越好。结果提示,大学生的记忆存在自我和专业参照效应,但自我参照效应更强;专业认同是专业参照效应强弱的影响因素之一。     

Common mechanisms of executive attention underlie executive function and effortful control in children

Executive Function (EF) and Effortful Control (EC) have traditionally been viewed as distinct constructs related to cognition and temperament during development. More recently, EF and EC have been implicated in top‐down self‐regulation ‐ the goal‐directed control of cognition, emotion, and behavior. We propose that executive attention, a limited‐capacity attentional resource subserving goal‐directed cognition and behavior, is the common cognitive mechanism underlying the self‐regulatory capacities captured by EF and EC. We addressed three related questions: (a) Do behavioral ratings of EF and EC represent the same self‐regulation construct? (b) Is this self‐regulation construct explained by a common executive attention factor as measured by performance on cognitive tasks? and (c) Does the executive attention factor explain additional variance in attention deficit hyperactivity disorder (ADHD) problems to behavioral ratings of self‐regulation? Measures of performance on complex span, general intelligence, and response inhibition tasks were obtained from 136 preadolescent children (M = 11 years, 10 months, SD = 8 months), along with self‐ and parent‐reported EC, and parent‐reported EF, and ADHD problems. Results from structural equation modeling demonstrated that behavioral ratings of EF and EC measured the same self‐regulation construct. Cognitive tasks measured a common executive attention factor that significantly explained 30% of the variance in behavioral ratings of self‐regulation. Executive attention failed to significantly explain additional variance in ADHD problems beyond that explained by behavioral ratings of self‐regulation. These findings raise questions about the utility of task‐based cognitive measures in research and clinical assessment of self‐regulation and psychopathology in developmental samples.     

Associations of physical activity and gross motor skills with executive function in preschool children from low‐income South African settings

Executive function is foundational for cognitive development. Previous research has shown both gross motor skills and physical activity to be related to executive function. However, evidence for these relationships in the preschool years, as well as in low‐ and middle‐income countries is lacking. Therefore, this study aimed to investigate the relationships between components of executive function (inhibition, shifting and working memory) and gross motor skills (locomotor skills and object control skills) in a sample of preschool children from urban and rural low‐income settings in South Africa. Results revealed that inhibition and working memory, but not shifting, were associated with gross motor skills. More specifically: inhibition was associated with both locomotor [β = 0.20, p = 0.047] and object control skills [β = 0.24, p = 0.024], whereas working memory was only associated with locomotor skills [β = 0.21, p = 0.039]. Physical activity was not associated with inhibition and shifting but was negatively associated with working memory. These results elaborate a growing evidence base linking executive function and gross motor skills in the early years, and it is the first to look at specific associations of locomotor and object control skills with executive function in the South African context (a low‐ and middle‐income country).
