The self-reference effect in attention deficit hyperactivity disorder.

The self-memory system depends on the prioritization and capture of self-relevant information, so may be disrupted by difficulties in attending to, encoding and retrieving self-relevant information. The current study compares memory for self-referenced and other-referenced items in children with ADHD and typically developing comparison groups matched for verbal and chronological age. Children aged 5-14 (N = 90) were presented with everyday objects alongside an own-face image (self-reference trials) or an unknown child's image (other-referenced trials). They were asked whether the child shown would like the object, before completing a surprise source memory test. In a second task, children performed, and watched another person perform, a series of actions before their memory for the actions was tested. A significant self-reference effect (SRE) was found in the typically developing children (i.e. both verbal and chronological age-matched comparison groups) for the first task, with significantly better memory for self-referenced than other-referenced objects. However, children with ADHD showed no SRE, suggesting a compromised ability to bind information with the cognitive self-concept. In the second task, all groups showed superior memory for actions carried out by the self, suggesting a preserved enactment effect in ADHD. Implications and applications for the self-memory system in ADHD are discussed.

Mine for life: Charting ownership effects in memory from adolescence to old age.

This study investigates the self-reference effect (SRE) with an ownership memory task across several age groups, providing the first age exploration of implicit ownership memory biases from adolescence to older adulthood (N = 159). Using a well-established ownership task, participants were required to sort images of grocery items as belonging to themselves or to a fictitious unnamed Other. After sorting and a brief distractor task, participants completed a surprise one-step source memory test. Overall, there was a robust SRE, with greater source memory accuracy for self-owned items. The SRE attenuated with age, such that the magnitude of difference between self and other memory diminished into older adulthood. Importantly, these findings were not due to a deterioration of memory for self-owned items, but rather an increase in memory performance for other-owned items. Linear mixed effects analyses showed self-biases in reaction times, such that self-owned items were identified more rapidly compared with other owned items. Again, age interacted with this effect showing that the responses of older adults were slowed, especially for other-owned items. Several theoretical implications were drawn from these findings, but we suggest that older adults may not experience ownership-related biases to the same degree as younger adults. Consequently, SREs through the lens of mere ownership may attenuate with age.

Put you in the problem: Effects of self-pronouns on mathematical problem-solving.

Self-cues such as personal pronouns are known to elicit processing biases, such as attention capture and prioritisation in working memory. This may impact the performance of tasks that have a high attentional load like mathematical problem-solving. Here, we compared the speed and accuracy with which children solved numerical problems that included either the self-cue "you," or a different character name. First, we piloted a self-referencing manipulation with N = 52, 7 to 11 year-olds, testing performance on addition and subtraction problems that had either a single referent ("You"/"Sam") or more than one referent. We took into account operation and positioning of the pronoun and also measured performance on attention and working memory tasks. We found a robust accuracy advantage for problems that included "you," regardless of how many characters were included. The accuracy advantage for problems with a self-pronoun was not statistically associated with individual differences in attention or working memory. In our main study (9 to 11 year-olds, N = 144), we manipulated problem difficulty by creating consistently and inconsistently worded addition and subtraction problems. We found significantly higher speed and accuracy for problems that included "you." However, this effect varied by task difficulty, with the self-pronoun effect being strongest in the most difficult inconsistently worded, subtraction problems. The advantage of problems with a self-pronoun was not associated with individual differences in working memory. These findings suggest that self-cues like the pronoun "you" can be usefully applied in numerical processing tasks, an effect that may be attributable to the effects of self-cues on attention.

The cost of social influence: Own-gender and gender-stereotype social learning biases in adolescents and adults.

Pervasive gender gaps in academic subject and career choices are likely to be underpinned by social influences, including gender stereotypes of competence in academic and career domains (e.g., men excel at engineering, women excel at care), and model-based social learning biases (i.e., selective copying of particular individuals). Here, we explore the influence of gender stereotypes on social learning decisions in adolescent and adult males and females. Participants (Exp 1: N = 69 adolescents; Exp 2: N = 265 adults) were presented with 16 difficult multiple-choice questions from stereotypically feminine (e.g., care) and masculine (e.g., engineering) domains. The answer choices included the correct response and three incorrect responses paired with a male model, a female model, or no model. Participants' gender stereotype knowledge and endorsement were measured, and adolescents (Exp. 1) listed their academic subject choices. As predicted, there was a bias towards copying answers paired with a model (Exp.1: 74%, Exp. 2: 65% ps < .001). This resulted in less success than would be expected by chance (Exp. 1: 12%, Exp. 2: 16% ps < .001), demonstrating a negative consequence of social information. Adults (Exp 2) showed gender stereotyped social learning biases; they were more likely to copy a male model in masculine questions and a female model in feminine questions (p = .012). However, adolescents (Exp 1) showed no evidence of this stereotype bias; rather, there was a tendency for male adolescents to copy male models regardless of domain (p = .004). This own-gender bias was not apparent in female adolescents. In Exp 1, endorsement of masculine stereotypes was positively associated with selecting more own-gender typical academic subjects at school and copying significantly more male models in the male questions. The current study provides evidence for the first time that decision-making in both adolescence and adulthood is impacted by gender biases.

Gender stereotypes in UK children and adolescents: Changing patterns of knowledge and endorsement.

Across two studies, we investigated gender stereotype knowledge and endorsement in UK schoolchildren, and their impact on academic subject choice. In Study 1, children aged 9-11 (N = 68) and 13-15 (N = 61) completed a newly developed Gender Attribute scale assessing their knowledge and endorsement of gender stereotypes relating to academic subjects and occupations. Participants demonstrated gender stereotype knowledge and endorsement, although significantly higher knowledge than endorsement scores indicated a level of stereotype rejection. Stereotype knowledge was greater in the older age group, and older girls showed significantly higher levels of stereotype rejection than all other groups. In Study 2, children aged 13-15 (N = 165) completed the Gender Attribute scale and provided information on their school subject choices. Patterns of stereotype knowledge and endorsement followed those of Study 1. Subject choice information showed that boys selected significantly more masculine than feminine subjects, while girls chose a similar proportion of each. Further, boys' level of gender stereotype endorsement predicted their subject choices, while girls' did not. We suggest that in contemporary UK some progress is being made in relation to girls challenging stereotypes that work against them but that more work is needed to encourage boys into female-dominated disciplines.

Me first? Positioning self in the attentional hierarchy.

The attention system that allocates resources across competing aspects of the environment is influenced by biases toward particular types of stimuli, such as cues of threat (e.g., angry-face image), self-reference (e.g., own-face image), and current goals (e.g., food image when hungry). Here, we used dot probe tasks to investigate which of these stimulus types are prioritized in the attentional hierarchy, measuring response latency to dot probes presented in the same location as different face types. In Experiment 1, participants (N = 42) were presented with self, angry, and neutral face images in the dot probe task, which revealed a clear attentional bias for self-images over both angry and neutral images. In Experiment 2, each participant (N = 69) was assigned a self, angry, or neutral goal image for a secondary monitoring task designed to induce a temporary goal, and this image was included in the stimuli presented in the dot probe task. Again, self-cues were found to produce a strong attentional bias, but images associated with temporary goals were found to be the most effective source of attentional bias. Results are discussed in relation to the relative importance of self, threat, and temporary goal cues in the attentional hierarchy. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Amount of Learning and Signal Stability Modulate Emergence of Structure and Iconicity in Novel Signaling Systems.

Iterated language learning experiments that explore the emergence of linguistic structure in the laboratory vary considerably in methodological implementation, limiting the generalizability of findings. Most studies also restrict themselves to exploring the emergence of combinatorial and compositional structure in isolation. Here, we use a novel signal space comprising binary auditory and visual sequences and manipulate the amount of learning and temporal stability of these signals. Participants had to learn signals for meanings differing in size, shape, and brightness; their productions in the test phase were transmitted to the next participant. Across transmission chains of 10 generations each, Experiment 1 varied how much learning of auditory signals took place, and Experiment 2 varied temporal stability of visual signals. We found that combinatorial structure emerged only for auditory signals, and iconicity emerged when the amount of learning was reduced, as an opportunity for rote-memorization hampers the exploration of the iconic affordances of the signal space. In addition, compositionality followed an inverted u-shaped trajectory raising across several generations before declining again toward the end of the transmission chains. This suggests that detection of systematic form-meaning linkages requires stable combinatorial units that can guide learners toward the structural properties of signals, but these combinatorial units had not yet emerged in these unfamiliar systems. Our findings underscore the importance of systematically manipulating training conditions and signal characteristics in iterated language learning experiments to study the interactions between the emergence of iconicity, combinatorial and compositional structure in novel signaling systems.

Development of evaluative and incidental self-reference effects in childhood.

The self-reference effect (SRE) is the memory enhancement associated with information linked to self. Unlike 4- to 6-year-olds, adults show stronger memory enhancement when self-processing is "evaluative" (eSRE) than when self-processing is "incidental" (iSRE). Here, the developmental change from shallow to rich self-processing was programmatically explored. In Study 1, 6- to 11-year-olds (N = 189) showed an eSRE = iSRE pattern. However, eSRE magnitude was limited by ceiling effects. Avoiding ceiling effects, Study 2 showed a developmentally stable eSRE > iSRE pattern in 8- to 11-year-olds (N = 96; ηp2 = .06). Study 3 used a different paradigm to confirm that 8- to 11-year-olds are capable of evaluative encoding even without concrete self stimuli. However, the evaluative boost for children was smaller than that for adults (N = 104; ηp2 = .06). Results are discussed with reference to the developing self and its capacity to support memory.

The international focus-A neglected curriculum in global undergraduate nursing.

International learning in undergraduate global nurse education is recognised for promoting essential cultural competence. This can be addressed both at university; through the increasing use of collaborative technology and in practice, where the impact of international placements has promoted cultural sensitivity and outward student mobility. The authors debate the barriers that impede students' desire to take up international placements and review initiatives to promote a greater investment in this experience. The complexity and lack of transcultural principles that govern an international placement exchange have been addressed by one initiative to produce a robust pan-European quality audit process for clinical learning environments. In conclusion, the authors call for a greater and evaluated effort to increase global understanding and learning in the context of the COVID-19 response.

Global partnerships in nursing - A qualitative study in lessons for success.

Global nursing partnerships can develop cultural competence and standardisation across international nurse education programmes. Issues of context, cultural awareness and modes of engagement can influence the success of international collaboration. The 'Supporting Internationalisation of Traineeships in the Healthcare Sector' project, funded from 2017, brought together nine international partners from Finland, Poland, Spain and the UK to develop a pan-European quality audit process for clinical learning environments. As part of the evaluation, eight project partners were interviewed about the project and their criteria for a successful global partnership. The interviews allowed insight into previously hidden aspects of implementation. The importance of a scoping period for nursing global partnerships was highlighted that built on cultural diversity to explore common understandings. Attention to the use of prior expertise in internationalisation, or project objectives, could accelerate a global partnership to achieve a greater potential in its outcomes and cultural sensitivity. Framed in a clear structure, it is possible for global partnerships to embed ownership, autonomy and individual voice in partner organisations. The research concludes that only by growing international champions through funded and well constituted projects, that a genuine impact on the global health and educational needs in nursing can be met.

The Me in Memory: The Role of the Self in Autobiographical Memory Development.

This article tests the hypothesis that self-development plays a role in the offset of childhood amnesia; assessing the importance of both the capacity to anchor a memory to the self-concept, and the strength of the self-concept as an anchor. This research demonstrates for the first time that the volume of 3- to 6-year old's specific autobiographical memories is predicted by both the volume of their self-knowledge, and their capacity for self-source monitoring within self-referencing paradigms (N = 186). Moreover, there is a bidirectional relation between self and memory, such that autobiographical memory mediates the link between self-source monitoring and self-knowledge. These predictive relations suggest that the self-memory system is active in early childhood.

The I in autism: Severity and social functioning in autism are related to self-processing.

It is well established that children with autism spectrum disorder (ASD) show impaired understanding of others and deficits within social functioning. However, it is still unknown whether self-processing is related to these impairments and to what extent self impacts social functioning and communication. Using an ownership paradigm, we show that children with ASD and chronological- and verbal-age-matched typically developing (TD) children do show the self-referential effect in memory. In addition, the self-bias was dependent on symptom severity and socio-communicative ability. Children with milder ASD symptoms were more likely to have a high self-bias, consistent with a low attention to others relative to self. In contrast, severe ASD symptoms were associated with reduced self-bias, consistent with an 'absent-self' hypothesis. These findings indicate that deficits in self-processing may be related to impairments in social cognition for those on the lower end of the autism spectrum. Statement of contribution What is already known on this subject? Impaired self-processing in autism is linked to social and cognitive deficits. There are discrepancies across the literature, with reports of both intact and impaired self-processing in autism. Ownership tasks are developmentally appropriate and have shown to induce self-memory bias in young children. What does this study add? Using an ownership task, children with autism showed a significant self-memory bias, greater than typical peers. Severity was negatively correlated with level of self-bias, potentially explaining the previous discrepancies. Severe autism symptoms are associated with an 'absent self', and mild autism symptoms reduce attention to others.

Context and Perceptual Salience Influence the Formation of Novel Stereotypes via Cumulative Cultural Evolution.

We use a transmission chain method to establish how context and category salience influence the formation of novel stereotypes through cumulative cultural evolution. We created novel alien targets by combining features from three category dimensions-color, movement, and shape-thereby creating social targets that were individually unique but that also shared category membership with other aliens (e.g., two aliens might be the same color and shape but move differently). At the start of the transmission chains each alien was randomly assigned attributes that described it (e.g., arrogant, caring, confident). Participants were given training on the alien-attribute assignments and were then tested on their memory for these. The alien-attribute assignments participants produced during test were used as the training materials for the next participant in the transmission chain. As information was repeatedly transmitted an increasingly simplified, learnable stereotype-like structure emerged for targets who shared the same color, such that by the end of the chains targets who shared the same color were more likely to share the same attributes (a reanalysis of data from Martin et al., which we term Experiment 1). The apparent bias toward the formation of novel stereotypes around the color category dimension was also found for objects (Experiment 2). However, when the category dimension of color was made less salient, it no longer dominated the formation of novel stereotypes (Experiment 3). The current findings suggest that context and category salience influence category dimension salience, which in turn influences the cumulative cultural evolution of information.

Evaluating a nursing erasmus exchange experience: Reflections on the use and value of the Nominal Group Technique for evaluation.

This paper discusses the use of Nominal Group Technique (NGT) for European nursing exchange evaluation at one university. The NGT is a semi-quantitative evaluation method derived from the Delphi method popular in the 1970s and 1980s. The NGT was modified from the traditional version retaining the structured cycles and but adding a broader group discussion. The NGT had been used for 2 successive years but required analysis and evaluation itself for credibility and 'fit' for purpose which is presented here. It aimed to explore nursing students' exchange experiences and aid programme development futures exchanges and closure from exchange. Results varied for the cohorts and students as participants enthusiastically engaged generating ample data which they ranked and categorised collectively. Evaluation of the NGT itself was two fold: by the programme team who considered purpose, audience, inclusivity, context and expertise. Secondly, students were asked for their thoughts using a graffiti board. Students avidly engaged with NGT but importantly also reported an effect from the process itself as an opportunity to reflect and share their experiences. The programme team concluded the NGT offered a credible evaluation tool which made use of authentic student voice and offered interactive group processes. Pedagogially, it enabled active reflection thus aiding reorientation back to the United Kingdom and awareness of 'transformative' consequences of their exchange experiences.

Simulation-based mentalizing generates a "proxy" self-reference effect in memory.

The self-reference effect (SRE) in memory is thought to depend on specialized mechanisms that enhance memory for self-relevant information. We investigated whether these mechanisms can be engaged "by proxy" when we simulate other people, by asking participants to interact with two virtual partners: one similar and one dissimilar to self. Participants viewed pairs of objects and picked one for themselves, for their similar partner, or their dissimilar partner. A surprise memory test followed that required participants to identify which object of each pair was chosen, and for whom. Finally, participants were shown both partners' object pairs again, and asked to indicate their personal preference. Four key findings were observed. Overlap between participants' own choice and those made for their partner was significantly higher for the similar than the dissimilar partner, revealing participants' use of their own preferences to simulate the similar partner. Recollection of chosen objects was significantly higher for self than for both partners and, critically, was significantly higher for similar than dissimilar partners. Source confusion between self and the similar partner was also higher. These findings suggest that self-reference by proxy enhances memory for non-self-relevant material, and we consider the theoretical implications for functional interpretation of the SRE.

Culture modulates implicit ownership-induced self-bias in memory.

The relation of incoming stimuli to the self implicitly determines the allocation of cognitive resources. Cultural variations in the self-concept shape cognition, but the extent is unclear because the majority of studies sample only Western participants. We report cultural differences (Asian versus Western) in ownership-induced self-bias in recognition memory for objects. In two experiments, participants allocated a series of images depicting household objects to self-owned or other-owned virtual baskets based on colour cues before completing a surprise recognition memory test for the objects. The 'other' was either a stranger or a close other. In both experiments, Western participants showed greater recognition memory accuracy for self-owned compared with other-owned objects, consistent with an independent self-construal. In Experiment 1, which required minimal attention to the owned objects, Asian participants showed no such ownership-related bias in recognition accuracy. In Experiment 2, which required attention to owned objects to move them along the screen, Asian participants again showed no overall memory advantage for self-owned items and actually exhibited higher recognition accuracy for mother-owned than self-owned objects, reversing the pattern observed for Westerners. This is consistent with an interdependent self-construal which is sensitive to the particular relationship between the self and other. Overall, our results suggest that the self acts as an organising principle for allocating cognitive resources, but that the way it is constructed depends upon cultural experience. Additionally, the manifestation of these cultural differences in self-representation depends on the allocation of attentional resources to self- and other-associated stimuli.

The function of the self-attention network.

This commentary links Humphrey and Sui's proposed Self-attention Network (SAN) to the memory advantage associated with self-relevant information (i.e., the self-reference effect). Articulating this link elucidates the functional quality of the SAN in ensuring that information of potential importance to self is not lost. This adaptive system for self-processing mirrors the cognitive response to threat stimuli, which also elicit attentional biases and produce characteristically enhanced, episodic representations in memory. Understanding the link between the SAN and memory is key to comprehending more broadly the operation of the self in cognition.

The spontaneous formation of stereotypes via cumulative cultural evolution.

All people share knowledge of cultural stereotypes of social groups--but what are the origins of these stereotypes? We examined whether stereotypes form spontaneously as information is repeatedly passed from person to person. As information about novel social targets was passed down a chain of individuals, what initially began as a set of random associations evolved into a system that was simplified and categorically structured. Over time, novel stereotypes emerged that not only were increasingly learnable but also allowed generalizations to be made about previously unseen social targets. By illuminating how cognitive and social factors influence how stereotypes form and change, these findings show how stereotypes might naturally evolve or be manipulated.
