The Roles of Empathy and Theory of Mind in Sexual Violence Perpetration: An Integrated Social Information Processing Framework.

Empathy is an aspect of social cognition which has gained much attention to explain sexual violence perpetration, with research resulting in mixed and contradictory findings. Another aspect of social cognition, which has been linked to, and even used synonymously with, cognitive empathy is Theory of Mind (ToM). However, research is severely lacking on the role which ToM may play in sexual violence. Hence, in order to elucidate such issues, following a theoretical discussion of these concepts, we propose an integrated Social Information Processing (SIP) framework to understand how empathy and ToM may be involved in sexual violence perpetration. This framework includes the steps laid out by Crick and Dodge's original SIP model, the emotional processes emphasised by Lemerise and Arsenio, the empathy stages identified by Marshall and colleagues, and our propositions concerning the role played by ToM. In this theoretical article, we argue that ToM and empathy are primarily involved in earlier SIP stages, but may have repercussions on subsequent stages as SIP is cyclical. Nonetheless, greater research is needed to conclusively identify where deficits lie. In terms of clinical implications, we recommend that empathy and ToM be targeted in interventions (primary, secondary and tertiary) using cognitive-behavioural therapy principles which are involved in, and affect, SIP.

CSR and its impact on employees’ emotions: social information processing

Purpose This study aims to investigate the role of corporate social responsibility (CSR) in reducing employees’ negative emotions. Based on social information processing, a new conceptual framework was developed and tested in the Indian context. Design/methodology/approach Cross-sectional design was used in the study. A total of 240 managers of financial institutions were surveyed through a self-administered questionnaire, and the responses were collected using a convenience sampling technique. Findings The findings indicated that CSR induces compassion and reduces employees’ negative emotions. Contrary to expectations, compassion did not emerge as a mediator in the relationship between CSR and negative emotions. Originality/value The findings contribute to the literature by scrutinizing the persuading influence of CSR on employees’ negative emotions directly and indirectly through compassion. Furthermore, this study also tested the moderating effects of positive emotion in the relationship between CSR and negative emotions. The linkage between CSR and negative emotions was established by introducing the social information processing mechanism, adding another novelty to the literature.

Angry or neutral, it does not matter to me: Implicit processing of facial emotions is not related to peer victimization experiences.

The aim of this study was to examine whether prolonged victimization relates to differential processing of emotions. Based on the social information processing theory, it was hypothesized that prolonged victimization would modulate emotion processing, such that victimization relates to a heightened attentional focus toward negative facial expressions and increased amygdala activation in response to negative facial expressions. We targeted a unique sample of 83 children (Mage = 10.6, 49.4% girls) whose victimization history in the past 2 years was available. An Emotional Dot-Probe Task and an Emotion Processing fMRI Task were administered to the participants. Findings included that victimization did not relate significantly to a heightened attentional focus on happy, angry, or fearful expressions. Viewing facial expressions resulted in the activation of the posterior medial frontal cortex, bilateral insula, bilateral fusiform face area, and the right amygdala and hippocampus, which was not related to victimization, nor was victimization related to activation in the amygdala or the social brain regions (medial prefrontal cortex, temporoparietal junction, precuneus, posterior superior temporal sulcus) when viewing specific emotional (happy, angry, afraid, sad) expressions. Together, these results do not provide evidence that implicit emotion processing without social context relates to victimization. Future research should replicate these results and further examine emotion processing in relation to severe victimization experiences and support systems, such as friendships or parenting, on emotion processing.

Salience Network in Autism: preliminary results on functional connectivity analysis in resting state.

The literature suggests that alterations in functional connectivity (FC) of the Salience Network (SN) may contribute to the manifestation of some clinical features of Autism Spectrum Disorder (ASD). The SN plays a key role in integrating external sensory information with internal emotional and bodily information. An atypical FC of this network could explain some symptomatic features of ASD such as difficulties in self-awareness and emotion processing and provide new insights into the neurobiological basis of autism. Using the Autism Brain Imaging Data Exchange II we investigated the resting-state FC of core regions of SN and its association with autism symptomatology in 29 individuals with ASD compared with 29 typically developing (TD) individuals. In ASD compared to TD individuals, seed-based connectivity analysis showed a reduced FC between the rostral prefrontal cortex and left cerebellum and an increased FC between the right supramarginal gyrus and the regions of the middle temporal gyrus and angular gyrus. Finally, we found that the clinical features of ASD are mainly associated with an atypical FC of the anterior insula and the involvement of dysfunctional mechanisms for emotional and social information processing. These findings expand the knowledge about the differences in the FC of SN between ASD and TD, highlighting atypical FC between structures that play key roles in social cognition and complex cognitive processes. Such anomalies could explain difficulties in processing salient stimuli, especially those of a socio-affective nature, with an impact on emotional and behavioral regulation.

Unveiling the mechanisms between project manager leadership competencies and team performance: an empirical study

Purpose This study aims to explore the influence of construction project manager competencies on team performance, using structural equation modeling (SEM) within the framework of social information processing theory. It investigates the multidimensional nature of project manager competencies and their impact on team processes and outcomes. Additionally, the study examines the mediating role of team processes in the relationship between competencies and team performance. Design/methodology/approach Drawing on data collected from 483 construction professionals in China, this study uses SEM to analyze the relationships among project manager competencies, team processes and team performance. Findings The results demonstrate a significant and positive effect of competencies on team performance. Specifically, task-related competencies directly contribute to performance, while people-related competencies enhance leader-member relations, and self-related competencies exert a gradual, cumulative influence. Moreover, the research confirms a three-factor competency structure and elucidates the nuanced mediating roles of team learning, monitoring and climate in the competency-performance relationship, shedding light on how specific competencies affect different stages of team development. Originality/value This study contributes to project management literature by applying social information processing theory to elucidate how project managers influence team cognition through competencies. From a practical standpoint, it advocates for a competency-based approach to project manager selection and training, aiming to enhance team performance. Overall, this research advances the understanding of the intricate interplay between project manager competencies and team performance, using SEM and a theoretical perspective rooted in social information processing theory.

Altered neural response to social awkwardness in schizophrenia spectrum disorders.

Individuals with a schizophrenia spectrum disorder (SSD) have difficulties with social information processing, including mental state attribution, or "theory of mind" (ToM). Prior work has shown that these difficulties are related to disruption to the neural network subserving ToM. However, few such studies utilize naturalistic stimuli that are more representative of daily social interaction. Here, SSD and Non-SSD individuals underwent fMRI while watching The Office to better understand how the ToM network responds to dynamic and complex social information, such as socially awkward moments. We find that medial prefrontal cortex tracks less with moment-to-moment awkwardness in SSD individuals. We also find a broad decrease in functional connectivity in the ToM network in SSD. Furthermore, neural response during awkward moments and functional connectivity was associated with psychotic experiences and social functioning. These results suggest that during naturalistic, socially awkward moments where mental state attribution is critical, individuals with SSD fail to recruit key regions of the ToM network, possibly contributing to decreased social understanding and impaired functioning.

Medial prefrontal cortex-periaqueductal gray circuit overcomes anxiety-like behavior in male mice following adversity

BackgroundInescapable stress leads to various long-lasting physical and mental dysfunctions. Acute stress exposure is linked to a high risk of psychological disorders, such as anxiety disorders. The medial prefrontal cortex (mPFC) and periaqueductal gray (PAG) are anatomical regions associated with social information processing and emotional valence. However, it is unclear whether mPFC projections to the PAG are involved in anxiety behavior. MethodsIn this study, an anxiety model by an inescapable foot shock was established. And used immunofluorescence, FosTRAP strategy, specific chemogenetics, optogenetics and behavior test to reveal that the stressful event increased the anxiety behavior of mice after exposure to foot shock and activation of mPFC-PAG circuitry can improve anxiety-like behavior and the locomotor behavior of mice. ResultsNotably, FosTRAP results indicated that c-Fos expression in the PAG and mPFC is increased during foot shock, but inhibiting these brain regions did not significantly alleviate anxiety behavior. Additionally, chemogenetic activation of mPFC projections to the PAG improved anxiety-like behavior and locomotor activity in mice only during stress. Optogenetic activation of the mPFC-PAG circuitry increased the total distance traveled in the open field test and slightly increased the number of entries into the center area, while optogenetic inhibition slightly increased anxiety-like behavior in control mice. LimitationThe limitation of this study is that only the changes and regulations of mPFC-PAG of anxiety male animals were studied. ConclusionsOverall, our findings suggest that the valence-encoding mPFC-PAG circuit modulates anxiety, and that these projections may be potential targets for treatment of anxiety disorders.

When feeling safe is not enough to voice: Is emotional energy the missing key?

Organizations often seek ways to motivate their employees to make positive contributions. Drawing on the proactive motivational model and social information processing (SIP) theory, this study aims to explore the effects of hotel employees’ emotional energy on supportive and constructive voice and the moderating role of psychological safety climate. The proposed model was tested using data collected from hospitality and tourism employees through Prolific (n = 390). The results indicate that emotional energy has a direct positive influence on supportive and constructive voice, and psychological safety climate moderates the relationship between emotional energy and constructive voice but not supportive voice. This research contributes to the voice behavior literature by looking at specific dimensions of voice behavior and provides additional empirical evidence for the proactive motivational model.

An innovative storytelling intervention to reduce school aggression among schoolchildren with reactive and proactive aggression.

It is a pioneering study to reduce reactive and proactive aggression in high-risk children aged 6-10 through an innovative intervention through storytelling. The original storytelling group intervention was based on the social information processing model, specifically tailor-made for the distinctive functions and motives of reactive and proactive aggression. Eighty-seven elementary schools in Hong Kong were recruited through open recruitment, and 15 schools were randomly selected. Four thousand eighty-six children (2,292 boys and 1,794 girls) from Grades 1 to 4 completed the screening, and 371 high-risk students (280 boys and 91 girls) with reactive and proactive aggression were recruited based on the inclusion criteria. We conducted a randomized controlled trial with a longitudinal design. Participants were then randomly assigned to the storytelling intervention, placebo, or control group. The group intervention consisted of 10 weekly 1-hr sessions. The participants were assessed at the baseline, after treatment, and 6 months after treatment by self-report and parent report. Longitudinal data were analyzed by linear mixed models. The results demonstrate the effectiveness of the storytelling group intervention in reducing aggression. Compared with the placebo and control, the storytelling intervention further reduced self-reported aggressive behaviors but not parent-reported externalizing and internalizing problems. This storytelling intervention could be adopted in schools and other settings to treat high-risk children with aggressive behaviors without stigmatization. It can positively impact schools and society by reducing bullying and delinquency. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Protocol for a randomized controlled trial of strength at home in Israel: A trauma informed intervention for intimate partner violence based on a social-information processing model.

The social information processing (SIP) model of trauma and intimate partner violence (IPV), which emphasizes the impact of trauma on one's ability to accurately process social information and subsequent failure to generate and enact nonaggressive responses, has gained attention in the United States. Recent clinical trial evidence suggests that the Strength at Home (SAH) intervention, a 12-session program that is based on this model, is efficacious in reducing and ending abusive behavior among U.S. veterans. However, such a clinical trial has yet to be conducted among a civilian population nor in a different cultural context (e.g., Israel). This paper describes the methods of a randomized controlled trial to test the efficacy of SAH compared to a treatment as usual comparison condition in Israel. 300 men referred (court-, clinically-, and self-referred) to IPV intervention from adult outpatient clinics at Social Affairs and Social Services offices in Israel will be randomly assigned to the SAH intervention or a treatment-as-usual comparison group. Outcomes are measured at six timepoints (baseline, post-treatment, and four 3-month follow-ups). The primary outcome is use of IPV; however, we will also examine reductions in SIP deficits. Secondary outcomes include symptoms of posttraumatic stress disorder (PTSD), depression, and anxiety, and changes in emotion regulation strategies. Study findings will determine the efficacy of SAH in a civilian population and in a different cultural context. Additionally, findings will determine whether SIP is a mechanism of change for such intervention.

Opening the Pandora box: Neural processing of self-relevant negative social information.

Curiosity is a powerful motivator of information-seeking behavior. People seek not only positive, but also aversive social information about others. However, whether people also seek unfavorable social information about themselves, as well as the neural mechanisms that may drive such seemingly counterintuitive behavior remain unclear. To address this gap, we developed a novel electroencephalography-compatible Social Incentive Delay (SID) task, which was implemented in 30 healthy young adults as they responded as fast as possible to a target to receive positive or avoid negative comments about their own or about others' Instagram photos. Reaction times were slower for negative vs positive comments' conditions, but only for participants' own photos, revealing less motivation to avoid negative rather than seek positive self-relevant social feedback. Coherently, receiving negative feedback, as opposed to avoiding it, evoked larger amplitudes in the Reward Positivity (RewP) and FB-P3 time-range, especially for participants' own photos, indicating that receiving a negative comment was more rewarding and more salient than not receiving any comment at all. Our findings challenge prior evidence suggesting that humans instinctively avoid aversive stimuli, and they shed light on the neurophysiological mechanisms that may underlie this counterintuitive behavior.

From Motion to Emotion: Visual Pathways and Potential Interconnections.

The two visual pathway description of Ungerleider and Mishkin changed the course of late 20th century systems and cognitive neuroscience. Here, I try to reexamine our laboratory's work through the lens of the Pitcher and Ungerleider new third visual pathway. I also briefly review the literature related to brain responses to static and dynamic visual displays, visual stimulation involving multiple individuals, and compare existing models of social information processing for the face and body. In this context, I examine how the posterior STS might generate unique social information relative to other brain regions that also respond to social stimuli. I discuss some of the existing challenges we face with assessing how information flow progresses between structures in the proposed functional pathways and how some stimulus types and experimental designs may have complicated our data interpretation and model generation. I also note a series of outstanding questions for the field. Finally, I examine the idea of a potential expansion of the third visual pathway, to include aspects of previously proposed "lateral" visual pathways. Doing this would yield a more general entity for processing motion/action (i.e., "[inter]action") that deals with interactions between people, as well as people and objects. In this framework, a brief discussion of potential hemispheric biases for function, and different forms of neuropsychological impairments created by focal lesions in the posterior brain is highlighted to help situate various brain regions into an expanded [inter]action pathway.

You say it‘s not me: the influence of offering external explanations of rejection and acceptance behavior on the perception of benevolence in borderline personality disorder

BackgroundInterpersonal impairments in patients diagnosed with borderline personality disorder (BPD) are characterized by the fear of being rejected and high levels of loneliness. Potential underlying factors are alterations in the processing of social interactions and the associated perceptions of social partners. In this regard, BPD patients tend to attribute the cause of negative rather than positive events to their own person and to perceive others as less trustworthy than healthy controls (HCs). To date, no study has investigated whether the effect of experimentally influenced causal attributions of social interactions on the perception of a social partner differs between BPD patients and HCs.MethodsA new virtual reality paradigm was developed to investigate the perception of benevolence following the induction of social rejection and acceptance, while experimentally manipulating whether an external cause for this behavior was provided. The data of 62 participants (32 HCs, 30 BPD patients) were analyzed using linear mixed-effects models. Associations of benevolence ratings with attributional style, rejection sensitivity, self-esteem, childhood trauma, and loneliness were investigated via correlational and multiple linear regression analyses.ResultsAcross both groups, a social partner was rated as less benevolent following rejection than following acceptance. An external explanation mitigated this negative effect of rejection. Overall, benevolence ratings were lower in BPD patients than in HCs. This group difference was stronger following acceptance than following rejection. Independent of acceptance and rejection, an external explanation was associated with a higher level of benevolence only in the HC group. No associations of the effects of the experimental conditions with attributional style, childhood trauma, rejection sensitivity, self-esteem, or loneliness were found.ConclusionOur findings indicate that acceptance and provided external explanations for rejection have a less positive impact on the perception of a social partner’s attitude toward oneself in BPD patients than in HCs. More research is needed to identify predictors of benevolence perception and which steps of social information processing are altered. The therapeutic implications include the importance of strengthening the perception and enjoyment of being accepted as well as improving the mentalizing ability of BPD patients.

The Relationship Between School Organizational Climate and Teachers' Organizational Citizenship Behaviors: The Mediating Role of Teaching Efficacy and Moderating Role of Optimistic Traits.

This study examined the relationship between school organizational climate and teachers' organizational citizenship behavior, as well as the mediating role of teaching efficacy and the moderating role of optimistic traits. This study was based on social information processing theory, resource conservation theory, and the broaden-and-build theory of positive emotions. We conducted a comprehensive survey of 500 educators from Chinese primary and secondary schools using the Organizational Citizenship Behavior Questionnaire, School Organizational Climate Scale, Sense of Teaching Efficacy Scale, and Optimistic Traits Questionnaire as assessment tools. The results demonstrated that (1) school organizational climate significantly and positively predicted teachers' organizational citizenship behaviors; (2) teaching efficacy partially mediated the relationship between school organizational climate and teachers' organizational citizenship behaviors; and (3) optimistic traits moderated the second half of the mediation model in which school organizational climate influenced teachers' organizational citizenship behaviors through teaching efficacy. Our findings indicated that school organizational climate was an important environmental factor affecting teachers' organizational citizenship behaviors through their sense of teaching efficacy. Optimistic traits had an important protective effect on teachers' organizational citizenship behaviors.

The association between maternal social information processing and preschool children social and learning problems via maternal insightfulness and children's social information processing

Research on early mother-child relationships have long established the associations between maternal thought processes and their children's thoughts and behaviors; however, the pathways behind this intergenerational transference have not yet been fully clarified. Accordingly, the current study focuses on the potential indirect associations between mothers’ social cognition, that is their thinking about social interactions, and children's behavior in preschool through the observed quality of the mother-child relationship and children's social cognition. Specifically, from mothers’ negative social information processing (SIP) patterns to children's social and learning behaviors via maternal insightfulness, dyadic mother-child emotional availability, and children's SIP patterns. The sample included 301 preschoolers and their mothers; data were collected via mother and child direct assessments, video-taped interactions, and teacher questionnaires. Results confirmed connections between mothers’ SIP and their insightfulness regarding their child's thoughts and behaviors, maternal insightfulness and dyadic emotional availability, insightfulness and children's SIP, and children's aggressive SIP patterns with their learning and social behaviors. A partial pathway was introduced and confirmed whereby maternal SIP predicted children's preschool behaviors via maternal insightfulness and children's SIP.

The Influence of Cognitive Appraisals on the Association between Callous-Unemotional Traits and Conduct Problems during Middle Childhood.

Existing research on callous-unemotional (CU) traits and conduct problems primarily focuses on the concurrent or unidirectional associations between these constructs (i.e., from CU traits to CP), with less attention given to their dynamic interplay during middle childhood. It is possible that socialization agents, such as peers, play a significant role in shaping the dynamic relation between CU traits and conduct problems early in development. Additionally, prior studies have shown that both CU traits and conduct problems are associated with poorer peer functioning. Considering the social information processing theory, which emphasizes the impact of cognitive processes on emotions and behavior in youth, this study evaluated the moderating role of cognitive appraisals (i.e., rumination, self-blame, and other-blame) in the context of peer conflict on the bidirectional association between callous-unemotional (CU) traits and conduct problems over the course of 1 academic year. The sample included 349 third- through fifth-grade students (51% boys; 53.2% Hispanic/Latinx) and their homeroom teachers (n = 30). At Time 1, children reported on their cognitive appraisals in response to peer conflict. Teachers provided reports of children's CU traits and conduct problems at Time 1 and Time 2. Results indicated that conduct problems and other-blame uniquely predicted increases in CU traits over time. Further, high levels of self-blame and rumination exacerbated the prospective link from CU traits to subsequent conduct problems. These findings highlight the importance of addressing cognitive processes in prevention approaches aimed at reducing the risk of conduct problems and CU traits among children.

Assessing Whether Negative Parenting Cognitions Bias Parent Report of Preschoolers' Externalizing Symptoms: A Regularized Moderated Non-Linear Factor Analysis Approach.

Parent report is frequently used to assess children's psychopathology, however, researchers have expressed concerns about the validity of parent reports. Some parental characteristics, attitudes, or beliefs may systematically bias a parent's report of their child's behaviors and functioning. Informed by social information processing models of parenting risk, parents with more difficulties reflecting on and interpreting their children's behavior may be at risk for less accurate reports. The present study conducted two regularized moderated non-linear factor analyses with LONGSCAN data to examine how parents' self-reported negative parenting cognitions were associated with structural parameters of parent-reported child aggression and attention problems. While differential item functioning (DIF) was present on the aggression and attention problems subscales as a function of negative parenting cognitions, the DIF was small in magnitude, inconsistent in directionality and did not significantly alter factor-level parameters. Negative parenting cognitions did demonstrate a small but significant negative impact on all latent externalizing factors (aggression and attention problems), such that caregivers with fewer negative parenting cognitions endorsed fewer items, and this was associated with a lower mean of each latent variable. Given that accounting for DIF did not contribute to meaningful differences in impact parameters or improve criterion validity, findings suggest that the aggression and attention subscales are functionally invariant to negative parenting cognitions, suggesting that externalizing symptoms can be reliability compared across parents of varying parenting cognitions.

Social network structure modulates neural activities underlying group norm processing: evidence from event-related potentials.

Social ties play a crucial role in determining the health and wellbeing of individuals. However, it remains unclear whether the capacity to process social information distinguishes well-connected individuals from their less-connected peers. This study explored how an individual's social network structure influences the dynamic processing of group norms, utilizing event-related potentials (ERPs). The study involved 43 university students from the same class who participated in a social network study measuring metrics such as real-life social network size, in-degree, out-degree, and betweenness centrality. Subsequently, 27 students participated in an EEG study assessing their willingness to engage in various exercises after being exposed to peer feedback or in its absence. The results indicate that an individual's social network structure is significantly associated with the dynamic processing of group norms. Notably, well-connected individuals exhibited larger ERP amplitudes linked to feedback (e.g., N200, P300, and LPP), greater functional segregation within the brain network (e.g., local efficiency and clustering coefficient), and enhanced synchronization within frontal area and across different brain areas. These findings highlight that well-connected individuals possess enhanced sensitivity and efficiency in processing social information, pointing to potential areas for further research on the factors influencing social network evolution.

Building a valuable professional development course: instructor effort vs. perceived student value of activities in an online biotechnology course

Providing undergraduate and graduate students with the appropriate preparation for transitioning to careers in their field after graduation is a key goal of higher education institutions, with many programs employing professional development workshops or courses to assist students and provide hands-on skills in this area. Although a wide variety of activities could benefit students, instructor and career specialist time is limited. Here, we describe an online biotechnology professional development course for undergraduate and graduate students, covering career exploration and the job search process, and the students’ perceptions of the activities offered based on survey data. Overall response to the course was positive, with students at various stages of their education indicating appreciation of most of the course assignments. Interestingly, students ranked the activities that took the most instructor time, namely review of application materials, mock interviews, and career panels, as the most valuable for their personal development. The career exploration aspects of the course influenced students to be open to new possibilities. However, students struggled to make time to complete the assignments for a fully online, largely asynchronous course. Discussion of the value of the course activities, their relevance to social cognitive career theory and cognitive information processing, and suggestions for smooth implementation are provided.

On the impact of zealots in a population of susceptible agents in a best-of-n problem within a heterogeneous network

Both humans and social animals live in groups and are frequently forced to choose between options with different qualities. When there are no leader agents controlling the group decision, consensus can be achieved through repeated interactions among group members. Various studies on collective decision-making illustrate how the dynamics of the opinions are determined by the structure of the social network and the methods that individuals use to share and update their opinion upon a social interaction. In this paper, we are interested in further exploring how cognitive, social, and environmental factors interactively contribute to determining the outcome of a collective best-of-n decision process involving asymmetric options, i.e., different costs and/or benefits for each option. We propose and study a novel model capturing those different factors, (i) the cognitive load in processing social information, (ii) the number of zealots (i.e., asocial agents who never change their opinion), (iii) the option qualities, (iv) the social connectivity structure, and (v) the degree centrality of the asocial agents (i.e., the number of neighbours). By using the heterogeneous mean-field approach, we study the impact of the above-mentioned factors in the decision dynamics. Our findings indicate that when susceptible agents, i.e., individuals who change their opinion to conform with others, use the voter model as a mechanism to update their opinion, both the number and the degree of connectivity of the zealots can lead the population to converge towards the lowest quality option. Instead, when susceptible agents use methods demanding a larger cognitive cost (e.g., the majority rule), the group is marginally impacted by the presence of zealots. The results of the analytical model are complemented and extended by agent-based simulations. Our analysis also shows that the network topology can modulate the influence of zealots on group dynamics. In fact, in homogeneous networks where all nodes have the same degree, any location of the zealots has similar impact on the group dynamics. Instead, when the network is heterogeneous, our simulations confirm the model predictions showing that placing the zealots in the network hubs (nodes with several neighbours) has a much larger impact than placing them in lower-degree nodes.
