'Constantly invalidated by an intolerant and uncaring world': Perceived etiology of suicidal thoughts among transgender, nonbinary, and gender expansive black, indigenous, and other people of color.

Transgender, nonbinary, gender-expansive (TNGE) Black, Indigenous, and Other People of Color (BIPOC) have one of the highest rates of suicidal ideation and suicide attempts. As recommended by the cultural framework of suicide, examining culturally relevant lay beliefs and attitudes, such as community perspectives on where suicidal ideation originates, is integral for suicide prevention. Doing so may aide in identifying avenues of support for TNGE BIPOC with chronic suicidal ideation. This study aimed to examine how TNGE BIPOC community members perceive the etiological foundation of suicidal ideation. Short-answer responses were collected from 110 participants in a national cross-sectional survey within the United States. Data were analyzed utilizing a directed content analysis approach to thematically categorize etiological factors. Participants described four major areas regarding perceived etiology of suicidal thoughts including: (1) chronic trauma and stress; (2) societal and cultural expectations; (3) biological factors; and (4) structural oppression. The most salient etiological factor was structural oppression which was endorsed by 60% of the sample. Results suggest that experiences of structural oppression should be incorporated in assessing TNGE BIPOC clients' beliefs about suicide and suicide prevention, given its relative saliency within this sample. Further research is needed to adequately understand how cumulative stress and social-cultural expectations impact the development of suicidal ideation among TNGE BIPOC.

East Asian international doctoral students’ role identity development in the United States

The U.S. attracts a significant number of international doctoral students each year. As these students navigate cultural and academic systems, understanding their unique experiences and challenges becomes crucial. This study explores the intricate nuances of motivation and identity negotiation in the lived experiences of six East Asian international doctoral students in the U.S. using collaborative autoethnography. We examined how role identities explain our experiences by employing the Dynamic Systems Model of Role Identity framework. Our reflections revealed (1) the salience of role identity components and structural relations and the impact of other role identities on resolving tensions; (2) the development of our researcher and teacher role identities within doctoral student role identity; and (3) resilience as both a cultural disposition and a dynamic process that evolves through the constant negotiation and renegotiation of our identities.

The shift of attention: Salience modulates the local vs global processing of auditory scenes in musicians and non-musicians.

This study addresses how salience shapes the perceptual organization of an auditory scene. A psychophysical task that was introduced previously by Susini, Jiaouan, Brunet, Houix, and Ponsot [(2020). Sci. Rep. 10(1), 16390] was adapted to assess how the ability of non-musicians and expert musicians to detect local/global contour changes in simple hierarchically-organized tone sequences is affected by the relative salience of local information in the timbre dimension. Overall, results show that salience enhanced local processing capacities, at the cost of global processing, suggesting a bottom-up reallocation of attention. Interestingly, for non-musicians, salience caused a reversal of the basic global-over-local processing prioritization as it is typically observed in expert musicians.

Anxiety-Like Behaviors in Mice Unmasked: Revealing Sex Differences in Anxiety Using a Novel Light-Heat Conflict Test.

Anxiety and chronic pain afflict hundreds of millions worldwide. Anxiety and pain are more prevalent in females compared to males. Unfortunately, robust sex differences in human anxiety are not recapitulated in rodent tests, and results from rodent pain studies frequently fail to translate clinically. Therefore, there is a need to develop tests that reflect the differential salience of anxiety or pain-related stimuli between the sexes. Accordingly, here we introduce the Thermal Increments Dark-Light (TIDAL) conflict test. The TIDAL test places an anxiety-relevant stimulus (dark vs. illuminated chamber) in conflict with a heat-related stimulus (incrementally heated vs. isothermic chamber); mice freely explore both apparatus chambers. Here, we aim to determine whether the TIDAL conflict test reveals in mice underappreciated sex differences in anxiety and/or heat sensitivity. We establish in four distinct experiments that females on the TIDAL conflict test persist substantially longer on the dark-heated plate, suggesting that female mice exhibit elevated anxiety-like behavior. Mice more strongly prefer the heated-dark plate on the TIDAL conflict test compared to control thermal place preference with both chambers illuminated. We also reveal that an anxiety-relieving drug, paroxetine, reduces mouse preference for the heating dark plate, supporting the validity of the TIDAL test. Therefore, our new TIDAL conflict test reliably unmasks the relative salience of anxiety (vs. heat sensitivity): mice that are female exhibit robust anxiety-like behaviors not consistently observed in classical tests. Future studies should incorporate TIDAL and other conflict tests to better understand rodent behavior and to identify mechanisms underlying anxiety and pain.

Exploring distinct and joint contributions of the locus coeruleus and the substantia nigra/ventral tegmental area complex to reward and valence processing using high-resolution fMRI

Abstract Dopaminergic neurons in the substantia nigra and the ventral tegmental area (SN/VTA) are classically viewed as key mediators in reward processing, while noradrenergic cells in the locus coeruleus (LC) are thought to modulate (negative) saliency processing. However, this conventional distinction is being revised by more recent research in animals. To explore the respective contributions of both the LC and SN/VTA in reward and valence processing in humans, we assessed fMRI data during stimulus encoding and response phase of a rewarded emotion-discrimination task (n = 38). Participants responded significantly faster to reward predicting and negative valence stimuli compared with their non-salient counterparts. LC activity was overall higher during trials involving reward prospect, and in particular for reward trials featuring positive valence, demonstrating an additive effect of reward and positive valence in LC. Moreover, LC activity was differentially increased for negative compared with positive valence in the response phase, indexing its role in invigorating responses to negative events. The SN/VTA showed increased activity in the response phase of reward trials (neutral valence) and negative valence trials (no reward), which aligns with coding relative saliency of these events in their respective contexts. LC modulations were accompanied by covariations in occipital cortex, suggesting noradrenergic contributions to visual prioritization of salient events. The findings underscore the sensitivity of both LC and SN/VTA to reward prospects and negative valence, challenging the dominant view of SN/VTA’s involvement in merely positive events and emphasizing their essential role in action invigoration above and beyond mere stimulus encoding. The intricate roles of the DA and NA system in reward and emotional valence processing in humans warrant further exploration and validation, given the limitations inherent to neuroimaging of deep brain structures.

The Effects of Cues to Ambient Darkness on Women's Willingness to Engage With Physically Strong Men.

Despite the overall desirability of men's upper body strength, women's preference for such features remains bounded to contexts in which the benefits exceed the potential costs. The relative salience of these costs could be augmented within ostensibly threatening environments, which could include one of ambient darkness. This study sought to determine whether women's interest in strong men would become downregulated in the presence of these cues. A sample of sorority women reported their reactions to meeting a hypothetical man on campus who was manipulated to appear either strong or weak with the image manipulated to be either at night or during the day. Although women reported feeling more comfortable around the weak man in the dark compared to the strong man, no difference emerged in their evaluations of strong men during the day and night. These findings suggest that women functionally shift their interest in strong men based on environmental cues that could implicate men as costly.

From analysis-by-synthesis to predictive coding and beyond: The Martingale Dynamics of Human Speech

Ken Stevens is best remembered for his seminal contributions in developing theories of speech perception based on detection of acoustic features emerging from quantal properties of speech. Equally influential, however, is his earlier proposal for speech perception through analysis-by-synthesis, whereby hypotheses generated by an internal model of speech production are evaluated against sensory input. These ideas are recapitulated in recent theories of predictive coding, which also rely on monitoring discrepancy between simulations of potential action and actual sensation. Analysis-by-synthesis and invariant feature detection are often considered as alternative top-down and bottom-up approaches to explaining perception. Both viewpoints can, however, be reconciled within mathematical theories of optimal estimation, which offer two alternative, equivalent solutions to the problem of extracting information about the state of a dynamical system from partial observations. Both solutions rely on internal models, but one involves calculating the prediction error, as in analysis-by-synthesis, whereas the other involves calculating the relative salience of the sensory field, akin to landmark detection. This presentation provides a historical overview of analysis-by-synthesis, from cybernetics to predictive coding, and also reviews parallel developments in martingale dynamics that unite analysis-by-synthesis with landmark detection.

Coordination in stag hunt games

Stag hunt games display a tension between a payoff superior option (stag) and a less risky but payoff inferior alternative (hare). We explore that tension by proposing a selection criterion (which we denote as relative salience) where subjects choose to coordinate in one option by comparing the salience of stag’s main aspect (its payoff) to the salience of hare’s main aspect (its risk) by accounting for both payoff-relevant factors and unobservable individual-specific (idiosyncratic) preferences. Using data from 10 experiments, we find that this criterion is a significant determinant of individual choices in stag-hunt games, outperforming other selection methods.

Weaker number sense accounts for impaired numerosity perception in dyscalculia: Behavioral and computational evidence.

Impaired numerosity perception in developmental dyscalculia (low "number acuity") has been interpreted as evidence of reduced representational precision in the neurocognitive system supporting non-symbolic number sense. However, recent studies suggest that poor numerosity judgments might stem from stronger interference from non-numerical visual information, in line with alternative accounts that highlight impairments in executive functions and visuospatial abilities in the etiology of dyscalculia. To resolve this debate, we used a psychophysical method designed to disentangle the contribution of numerical and non-numerical features to explicit numerosity judgments in a dot comparison task and we assessed the relative saliency of numerosity in a spontaneous categorization task. Children with dyscalculia were compared to control children with average mathematical skills matched for age, IQ, and visuospatial memory. In the comparison task, the lower accuracy of dyscalculics compared to controls was linked to weaker encoding of numerosity, but not to the strength of non-numerical biases. Similarly, in the spontaneous categorization task, children with dyscalculia showed a weaker number-based categorization compared to the control group, with no evidence of a stronger influence of non-numerical information on category choice. Simulations with a neurocomputational model of numerosity perception showed that the reduction of representational resources affected the progressive refinement of number acuity, with little effect on non-numerical bias in numerosity judgments. Together, these results suggest that impaired numerosity perception in dyscalculia cannot be explained by increased interference from non-numerical visual cues, thereby supporting the hypothesis of a core number sense deficit. RESEARCH HIGHLIGHTS: A strongly debated issue is whether impaired numerosity perception in dyscalculia stems from a deficit in number sense or from poor executive and visuospatial functions. Dyscalculic children show reduced precision in visual numerosity judgments and weaker number-based spontaneous categorization, but no increasing reliance on continuous visual properties. Simulations with deep neural networks demonstrate that reduced neural/computational resources affect the developmental trajectory of number acuity and account for impaired numerosity judgments. Our findings show that weaker number acuity in developmental dyscalculia is not necessarily related to increased interference from non-numerical visual cues.

The effect of chord duration on the relative salience of chord-type and voicing changes

This study investigates the effect of chord duration on the relative salience of chord-type and voicing changes. Participants ( N = 111) with varying levels of musical training were presented with sequences of five block chords on the piano and asked to indicate which chord sounded most different. Each sequence consisted of three identical chords and two oddballs, one with a voicing change and one with a chord-type change. All possible chord-type pairings between standard and oddball formed of major, minor, dominant seventh, major seventh, and minor seventh chords were tested. In addition, each sequence of five chords was tested using three chord duration conditions (500, 1,000, and 1,500 ms), and the durations were pseudo-randomized throughout the experiment. Chord-type changes became more salient with longer durations and this effect could be seen for all participants regardless of their levels of musical training. However, with higher level of musical training, chord-type changes became more salient across all duration conditions. Leman’s model of tonal contextuality suggests that the effect of duration in our experiment could be explained by sensory mechanisms related to echoic memory. The potential contribution of other factors to the effect of duration is discussed.

Frames and semantic roles in metaphorical mappings

Abstract Conceptual Metaphor Theory describes metaphorical mappings as correspondences between domains. Nevertheless, the interrelations of the mapped elements still need to be characterised. This study analyses metaphorical mappings from one situational frame in the cooking domain in American English and Peninsular Spanish. The aims are to elucidate to what extent each language primes particular semantic roles in the boiling frame for metaphorisation and explore the possible cultural implications of these cross-linguistic differences. The qualitative analysis reveals the contrastive relevance of semantic roles in frame mappings. In addition, the frequencies of boil and hervir metaphorical senses determine the degree of entrenchment and salience of metaphors cross-linguistically. The results suggest that the English boiling frame has a considerably broader scope as a source than the Spanish hervir frame. Additionally, the paper contrasts the relative saliency of the semantic roles mapped in those metaphors shared by both languages. Finally, cultural implications are discussed.

Neural Correlates of Crowding in Macaque Area V4.

Visual crowding refers to the phenomenon where a target object that is easily identifiable in isolation becomes difficult to recognize when surrounded by other stimuli (distractors). Many psychophysical studies have investigated this phenomenon and proposed alternative models for the underlying mechanisms. One prominent hypothesis, albeit with mixed psychophysical support, posits that crowding arises from the loss of information due to pooled encoding of features from target and distractor stimuli in the early stages of cortical visual processing. However, neurophysiological studies have not rigorously tested this hypothesis. We studied the responses of single neurons in macaque (one male, one female) area V4, an intermediate stage of the object-processing pathway, to parametrically designed crowded displays and texture statistics-matched metameric counterparts. Our investigations reveal striking parallels between how crowding parameters-number, distance, and position of distractors-influence human psychophysical performance and V4 shape selectivity. Importantly, we also found that enhancing the salience of a target stimulus could alleviate crowding effects in highly cluttered scenes, and this could be temporally protracted reflecting a dynamical process. Thus, a pooled encoding of nearby stimuli cannot explain the observed responses, and we propose an alternative model where V4 neurons preferentially encode salient stimuli in crowded displays. Overall, we conclude that the magnitude of crowding effects is determined not just by the number of distractors and target-distractor separation but also by the relative salience of targets versus distractors based on their feature attributes-the similarity of distractors and the contrast between target and distractor stimuli.

The Privileges We Do and Do Not See: The Relative Salience of Interpersonal and Circumstantial Benefits.

People attend more to disadvantages in their lives than to advantages, a phenomenon known as the Headwinds/Tailwinds Asymmetry. In seven studies (N = 1,526), we present an important caveat to this pattern: When people do notice and acknowledge their advantages, they mostly focus on the benefits they receive from other people (i.e., interpersonal benefits), as opposed to benefits they receive because of their demographics, personal traits, and life circumstances (i.e., circumstantial benefits). We demonstrate that people notice and remember others who helped them rather than hurt them and that they notice the help they receive from people more than from favorable, non-interpersonal factors. Finally, we find that the tendency to notice interpersonal advantages is related to a social norm requiring people to acknowledge helpful others (but not other advantages) and that changing the salience of this norm affects people's likelihood of acknowledging the support they have received from others.

Different self-damaging behaviours, similar motives? Testing measurement invariance of motives for nonsuicidal self-injury, disordered eating and substance misuse.

Theory and research suggest that distinct self-damaging behaviours (SDBs; e.g., nonsuicidal self-injury [NSSI], restrictive eating, binge eating, drug misuse, alcohol misuse) share similar motives. However, few studies have used a common self-report inventory to investigate the shared relevance and relative salience of motives for SDBs. Accordingly, the present study: (1) examined whether self-report scales assessing intrapersonal motives (i.e., relieving negative emotions, enhancing positive emotions, punishing oneself) and interpersonal motives (i.e., bonding with others, conforming with others, communicating distress, communicating strength, reducing demands) have invariant factor structures across SDBs; and (2) compared the salience of these motives across SDBs. 1018 adults (54.6% men, Mage = 35.41 years) with a history of SDBs were allocated to the following groups: NSSI (n = 213), restrictive eating (n = 200), binge eating (n = 200), drug misuse (n = 200) or alcohol misuse (n = 205). Participants reported on their motives for engaging in their allocated SDB. Measurement invariance analyses compared the factor structures and latent means of the motive scales across SDBs. The motive scales had comparable factor structures across SDBs. Intrapersonal motives were most strongly endorsed for NSSI and drug misuse. Interpersonal motives were most strongly endorsed for drug and alcohol misuse. All motives were least salient to restrictive eating. Results suggest that common motives underlie distinct SDBs and that they can be adequately assessed using a single self-report inventory. However, certain motives are more relevant to some SDBs than others, with restrictive eating being the most motivationally distinct SDB. This knowledge can inform transdiagnostic models and interventions for SDBs.

Right up their street? News media framing of the protest activities of far-right movement parties

Far-right parties have increasingly emphasised their movement-like characteristics as a novel mobilisation strategy. Existing studies of these so-called ‘far-right movement parties’ have concentrated on their internal organisation and communications to understand how they mediate between a movement and party identity through their own actions. Yet research is lacking on how this identity is constructed and presented by the news media: a crucial interface between institutional politics and public opinion. This paper pursues this enquiry with a comparative analysis of the newspaper coverage of two prominent cases—the German AfD and UKIP—and asks how coverage of their increasing involvement in protests has varied cross-nationally and evolved over time. The analysis reveals the relative salience of the protest activities of the far-right, along with the associated social movement actors, issues and frames used in the reporting. It shows that far-right party protest receives a low level of attention and tends to be accompanied by delegitimising framing, particularly when associated (extremist) movements are also present. In both cases analysed, a critical juncture generated increasing attention to far-right party protest, but also more delegitimising frames. The study provides new insights into the structures and processes which influence how the media has responded to the new far-right ‘movement party’ form in Europe, with implications for our understanding of contemporary far-right mobilisation strategies.

Leadership dynamics in musical groups: Quantifying effects of musical structure on directionality of influence in concert performance videos.

Music ensemble performance provides an ecologically valid context for investigating leadership dynamics in small group interactions. Musical texture, specifically the relative salience of simultaneously sounding ensemble parts, is a feature that can potentially alter leadership dynamics by introducing hierarchical relationships between individual parts. The present study extended previous work on quantifying interpersonal coupling in musical ensembles by examining the relationship between musical texture and leader-follower relations, operationalised as directionality of influence between co-performers' body motion in concert video recordings. It was hypothesised that the directionality of influence, indexed by Granger Causality, would be greater for 'homophonic' textures with a clear distinction between melody and accompaniment parts than for 'polyphonic' textures with less distinction between melody and accompaniment. This hypothesis was tested by using pose estimation algorithms to track instrumentalists' body movements in a string quartet and a clarinet quintet, and then applying Granger Causality analysis to their head motion to estimate directional influence between instrumentalist pairs for sections of the pieces that varied in texture. It was found that Granger Causality values were generally higher (indicating greater directionality of influence) for homophonic than polyphonic textures. Furthermore, considering melody and accompaniment instrument roles revealed more evidence for the melody instrument influencing accompanying instruments than vice versa, plus a high degree of directionality among accompanying instruments, in homophonic textures. These observed patterns of directional information flow in co-performer body motion are consistent with changing leader-follower relations depending on hierarchical relations between ensemble parts in terms of the relative salience of melodic material in the musical texture. The finding that automatic pose estimation can detect modulations of leadership dynamics in standard video recordings under naturalistic performance conditions has implications for investigating interpersonal coordination in large-scale music video datasets representing different cultural traditions, and for exploring nonverbal communication in group activities more generally.

What Feathers Flock Together? Examining College Students’ Perceptions of Social Model Similarity

Educators often try to motivate students for learning science, technology, engineering, and math (STEM) topics by exposing them to social models with similar characteristics. However, it is not clear what dimensions of similarities are most optimal for motivating students in STEM. The present study investigated different dimensions in which college students perceived similarity to their social models in chemistry (N = 265) and biology (N = 143) and how different dimensions of perceived similarity were related to students’ competence-related beliefs and task values for learning in those fields. Academic similarities—particularly similar abilities, efforts, and interests—were the most frequent dimensions of similarity college students reported perceiving with respect to their STEM social models. Additionally, perceiving similar academic abilities to a social model was associated with greater competence-related beliefs in both studies. The relative salience of different academic similarities and their relations to STEM motivation also differed by study, suggesting that the importance of academic similarity perceptions may differ across learning contexts. Educators should consider emphasizing academic similarities when using social models to recruit or retain college students in STEM, while also acknowledging contextual nuances that may attenuate how different perceptions of similarities motivate students.

Relative saliency affects attentional capture and suppression of color and face singleton distractors: evidence from event-related potential studies.

Prior research has yet to fully elucidate the impact of varying relative saliency between target and distractor on attentional capture and suppression, along with their underlying neural mechanisms, especially when social (e.g. face) and perceptual (e.g. color) information interchangeably serve as singleton targets or distractors, competing for attention in a search array. Here, we employed an additional singleton paradigm to investigate the effects of relative saliency on attentional capture (as assessed by N2pc) and suppression (as assessed by PD) of color or face singleton distractors in a visual search task by recording event-related potentials. We found that face singleton distractors with higher relative saliency induced stronger attentional processing. Furthermore, enhancing the physical salience of colors using a bold color ring could enhance attentional processing toward color singleton distractors. Reducing the physical salience of facial stimuli by blurring weakened attentional processing toward face singleton distractors; however, blurring enhanced attentional processing toward color singleton distractors because of the change in relative saliency. In conclusion, the attentional processes of singleton distractors are affected by their relative saliency to singleton targets, with higher relative saliency of singleton distractors resulting in stronger attentional capture and suppression; faces, however, exhibit some specificity in attentional capture and suppression due to high social saliency.
