    Gender difference in self-reported empathy : effects of task instructions and exposure to gender essentialism primes

    No full text
    Women often score higher on average than men on self-report measures of empathy. However, self-report estimates of empathic tendencies and other attributes could be susceptible to a range of biases. For instance, participants might respond in a manner that is socially desirable and aligns with gender stereotypes about empathic abilities. We examined whether gender differences in self-reported empathy were affected by a) manipulating task instructions or b) priming with fictive narratives describing gender differences as either fixed or malleable. In Study 1, participants (N = 154) completed questionnaire measures of empathy, social desirability and acceptance of stereotyping. Contrary to our prediction, gender differences in self-reported empathy were not larger when participants were told that we were measuring ‘empathy’. However, in both genders, average scores were higher for empathic concern in the ‘empathy’ condition than in the control condition, which suggests that describing the task as measuring empathy encouraged both male and female participants to present themselves as showing concern for others. Also, participants who scored higher on social desirability scored higher on empathic concern, suggesting a link between motivation to conform to social expectations and self-reported affective empathy. In Study 2, participants (N = 155) completed questionnaire measures of empathy, personality and gender essentialism. Gender differences in self-reported empathy were not larger in the condition that primed gender essentialism. However, women who scored high on empathic concern were more likely to align themselves with feminine adjectives, suggesting a link between self-reported consideration for others and feminine attributes. In both studies, on average, women scored significantly higher than men on self-reported empathic tendencies. Although the experimental manipulations did not impact empathy scores in either study, self-reported empathy appears to be related to social desirability and broader social attitudes, which suggests that a range of cultural and social factors might contribute to gender differences in empathy.Peer reviewe

KM acknowledges support from the Fundação para a Ciência e a Tecnologia (FCT) through the CEEC individual contract 2022.03809.CEECIND and research grants UIDB/04434/2020 and UIDP/04434/2020.We report on a search for variability in the young brown dwarf SST1624 (∼M7 spectral type, M ∼ 0.05 M⊙), previously found to feature an expanding gaseous shell and to undergo quasi-spherical mass loss. We find no variability on timescales of 1-6 hours. Specifically, on these timescales, we rule out the presence of a period with amplitude > 1%. A photometric period in that range would have been evidence for either pulsation powered by Deuterium burning or rotation near breakup. However, we see a 3% decrease in the K-band magnitude between two consecutive observing nights (a 10 σ result). There is also clear evidence for variations in the WISE lightcurves at 3.6 and 4.5 µm on timescales of days, with a tentative period of about 6 d (with a plausible range between 3 and 7 d). The best explanation for the variations over days is rotational modulation due to spots. These results disfavour centrifugal winds driven by fast rotation as mechanism for the mass loss, which, in turn, makes the alternative scenario – a thermal pulse due to Deuterium burning – more plausible.Peer reviewe

    Brexit and wellbeing : strained intergroup relations and positive intergroup contact predict wellbeing of Remainers and Leavers post Brexit

    Funding: This research was funded by the British Academy/Leverhulme Small Research Grant “Bridging the divide: Piloting an intergroup contact intervention in the context of Brexit” (SRG19\191421), awarded to the second (Principal Investigator) and first authors.Britain's exit from the European Union has divided the public, making it crucial to understand its implications for wellbeing. In two survey studies (N = 280, April 2020; N = 575, Nov 2020–July 2021) we examined how subjective wellbeing (mental wellbeing, MW; life satisfaction, LS) is predicted by Brexit attitudes and strained intergroup relations between UK Remainers and Leavers. We further tested whether positive intergroup contact is associated with wellbeing outcomes, via intergroup anxiety. Wellbeing was higher among Leavers than Remainers in Study 2. Negative intergroup emotions predicted lower MW for Remainers (Study 1). Perceived outgroup respect predicted higher MW for both groups, more so for Leavers (Study 2). Brexit identity negatively predicted wellbeing (Study 2), while contact quality positively predicted wellbeing (MW, Studies 1 and 2; LS, Study 2), via intergroup anxiety. Positive Brexit attitudes predicted greater wellbeing, especially for Leavers (Study 2). Greater wellbeing among Leavers may be attributed to the congruence between personal and perceived environmental values in the aftermath of Brexit. Strained intergroup relations were linked with lower wellbeing and positive contact was associated with higher wellbeing, via intergroup anxiety. Our research offers insights for interventions aimed at promoting wellbeing in polarized contexts by considering intergroup dynamics.Peer reviewe

    Does the experience of remembering differentially influence the factual accuracy of recognition, and confidence in its accuracy?

    No full text
    Remembering is typically viewed as unreliable and prone to errors, whereas highly confident recognition memory is often believed to be highly reliable and associated with high recognition accuracy. We evaluated these beliefs using memory for photographs of natural scenes in two studies: recognition memory to examine picture similarity effects in a 2-alternative forced-choice measure, and source memory to examine picture-location associations with a continuous retrieval accuracy measure. Additionally, we assessed the experience of remembering and its influence on judgments of confidence and memory accuracy. High confidence remembering was associated with high accuracy when perceptually or mnemonically similar lures were presented in the item recognition task. However, an association between high confidence and high accuracy was also seen in the absence of remembering for mnemonically similar lures. The confidence-accuracy inversion in the picture similarity task is speculated due to confidently (mis)remembering a similar picture stored in memory. Based on analyses of participant and trial level data, in both studies memory quality was strongly associated with confidence. Importantly, remembering moderated the association between recognition accuracy and confidence judgments, differentially influencing confidence more than it influenced accuracy. Memory quality moderated the association between source accuracy and confidence, the relationship being stronger for images remembered vividly. Our findings have implications for accounts of vividness, confidence, episodic memory, and eyewitness testimony. High confidence recognition may not in all cases reliably imply high accuracy. Highly vivid memories, confidently recollected, may not always be factually accurate.Peer reviewe

    “Taking delight in the temptation that torments them”a longing for the abyss, or the temptation of the Fall in libertine fiction

    No full text
    This article discusses the representation of erotic temptation in the libertine narratives of the eighteenth century. In these, we have authors who use the motif of temptation to explore their characters’ psyche while questioning the sanctions that Ancien Régime society imposed on sexuality—notably that of women. Our aim is to show that libertine temptations crystallize the internalization of Evil during the Enlightenment era, when temptation is in fact depicted as originating from a deep, innermost desire rather than an evil outside force. In this testing of his will, the individual discovers he is not the passive plaything of either demons or his own nature. Gifted with free will, he is characterized by his freedom to choose between good and evil, the pleasurable and the reasonable. This is why tempted characters view the Fall itself, despite its dangers, as an experience of freedom, and why temptation, for its part, is presented as a delicious thrill.Peer reviewe

    The making of a movement (together) : how climate activists perceive Greta Thunberg's leadership

    No full text
    Drawing on the Social Identity Theory of Leadership, this study explores how Greta Thunberg's influence emerges through group processes where her leadership is sustained among climate activists by perceptions of one of us and doing it for us. Using a qualitative survey of 108 climate activists from the United Kingdom, Turkey and Sweden, we examine how these perceptions are constructed and maintained by climate activists across different socio-political contexts. Although many activists view Thunberg as central to raising awareness and mobilising action, her leadership is seen as effective when it aligns with collective values and identity. Perceptions of her leadership are dynamic and shaped by her behaviour, rhetoric and evolving relationships with activists, media and political actors. Some participants expressed concern about her dominance in the public narrative and questioned her representativeness due to her privileged background (e.g., middle-class White European). Notably, identity prototypicality (one of us) and advancement (doing it for us) were closely linked: Activists often cited the same actions or messages as evidence of both. Findings highlight the mutual influence of leadership and movement identity. Although prototypical leaders embody the movement's identity and facilitate collective agency, leaders who inspire mobilisation and organise collective actions for activists to enact their identity are perceived as more prototypical.Peer reviewe

    Male mating behaviour is shaped by previous experience of both conspecific and heterospecific females in the seed bug Lygaeus simulans

    No full text
    Funding: This work was supported by the University of St Andrews.Mating decisions are often context-dependent. For example, choosy individuals may benefit from relaxing mate preferences if conspecific mates are scarce. However, prior experience of heterospecifics can also alter mating decisions, and this can influence the strength of species discrimination and/or sexual selection. Here, we investigate the effect of previous mating opportunities on the subsequent mating decisions of male Lygaeus simulans seed bugs, a species known both to experience reproductive interference (reproductive interactions with heterospecifics that are costly) and also male mate choice for larger females. We used a nested, hierarchical design whereby focal males were: (1) paired with a conspecific female or remained unpaired on day 1; (2) paired with a conspecific female, a heterospecific female, or were unpaired on day 6; (3) paired with a conspecific female or a heterospecific female on day 8. The sister species L. equestris provided the heterospecific partners. We found that males were less likely to mate with heterospecific L. equestris females if they had previously encountered a heterospecific, but only if copulation had not occurred during that encounter. Additionally, the willingness of males to copulate with conspecifics increased when males had prior conspecific experience, and decreased with prior heterospecific experience, suggesting that male pre-copulatory mating decisions are plastic and can be influenced by experience of both con- and heterospecifics.Peer reviewe

(grant CF21- 0425).Wildlife populations globally have experienced widespread historical declines due to anthropogenic and environmental impacts, yet for some species, contemporary management and conservation programmes have enabled recent recovery. The impacts of decline and recovery on genomic diversity and, vice versa, the genetic factors that contribute to conservation success or failure are rich areas for inquiry, with implications for shaping how we manage species into the future. To comprehensively characterise these processes in natural systems requires range-wide sampling and international collaboration, particularly for species with wide dispersal capabilities, broad geographic distributions, and complex regional metapopulation dynamics. Here, we present the first range- and genome-wide population genomic analysis of grey seals based on 3812 nuclear SNPs genotyped in 188 samples from 17 localities. Our analyses support the existence of three main grey seal populations centred in the NW Atlantic, NE Atlantic and Baltic Sea, and point to the existence of previously unrecognised substructure within the NE Atlantic. We detected remarkably low levels of genetic diversity in the NW Atlantic population, and demographic analyses revealed a turbulent history of NE Atlantic and Baltic Sea grey seals, with bottlenecks in the Middle Ages and the 20th century due to hunting and habitat alterations. We found some localities deviated from isolation by distance patterns, likely reflecting wide-scale metapopulation dynamics associated with recolonisation and recovery in regions where they were historically extirpated. We identify at least six grey seal genetic populations and reveal marked genetic effects of past declines and recent recovery across the species' range.Peer reviewe

    Funding: US Fleet Forces Command Marine Species Monitoring Program; Naval Facilities Engineering Command Southeast, Grant/Award Numbers: N62470-10-D-3011, N62470-15-D-8006.We report direct measurements of changes in diving and movement behavior for 53 goose-beaked whales (Ziphius cavirostris) in relation to experimentally controlled mid-frequency (3–4 kHz) active sonar (MFAS) signals. These signals simulate powerful Navy sources that have been associated with multiple mortal stranding events for this species. We deployed a multi-scale combination of tags to monitor individual whales, including 50 long-duration (weeks), coarse-resolution satellite-transmitting tags and 3 short-duration (hours), high-resolution archival depth, orientation, and acoustic tags. We evaluated behavioral responses during 13 experimental trials (9 MFAS; 4 no-MFAS controls), resulting in 72 exposure events; some individuals were exposed in multiple trials. Whales were exposed at known and modeled horizontal ranges from ~2 to >200 km and from below ambient noise levels to received levels (RLs) up to ~142 dB re: 1μPa (root-mean-square [RMS]). We investigated changes in diving and movement behavior separately, with a suite of metrics, descriptive evaluations, and statistical tests. We observed similar patterns and probabilities of behavioral changes for control trials and the lowest RL conditions (<100 dB). Above 100 dB RLs, increasingly prevalent and consistent responses occurred, including extended deep dives, prolonged periods between deep dives, directed spatial movement away from the source, and cessation of echolocation. Aspects of these cryptic responses typically persisted for hours following exposure but did not result in broad-scale habitat abandonment. Our study builds upon experimental and observational studies conducted on sonar testing ranges and expands our understanding of the response of this species to MFAS in a region where operational sonar use occurs far less commonly than on Navy testing ranges. These data are directly applicable in the conservation and effective management of this sensitive, protected species.Peer reviewe

    Long-read spatial transcriptomics of patient-derived clear cell renal cell carcinoma organoids identifies heterogeneity and transcriptional remodelling following NUC-7738 treatment

    No full text
    Funding: The authors acknowledge Research Computing at the James Hutton Institute for providing computational resources and technical support for the “UK’s Crop Diversity Bioinformatics HPC” (BBSRC grants BB/S019669/1 and BB/X019683/1), use of which has contributed to the results reported within this paper.Background: Clear cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer and is marked by pronounced intra-tumoural heterogeneity that complicates therapeutic response. Patient-derived organoids offer a physiologically relevant model to capture this diversity and evaluate treatment effects. When integrated with spatial transcriptomics, they might enable the mapping of spatially resolved transcriptional and isoform-level changes within the tumour microenvironment. Methods: We established a robust workflow for generating patient-derived ccRCC organoids, that are not passaged and retain original cellular components. These retain key features of the original tumours, including cancer cell, stromal, and immune components. Results: Spatial transcriptomic profiling revealed multiple transcriptionally distinct regions within and across organoids, reflecting the intrinsic heterogeneity of ccRCC. Isoform-level analysis identified spatially variable expression of glutaminase (GLS) isoforms, with heterogeneous distributions of both the GAC and KGA variants. Treatment with NUC-7738, a phosphoramidate derivative of 3′-deoxyadenosine, induced marked transcriptional remodelling of organoids, including alterations in ribosomal and mitochondrial gene expression. Conclusions: This study demonstrates that combining long-read spatial transcriptomics with patient-derived organoid models provides a powerful and scalable approach for dissecting gene and isoform-level heterogeneity in ccRCC and for elucidating spatially resolved transcriptional responses to novel therapeutics.Peer reviewe
