  • Susceptibility to Violent Extremism: Integrating Personality and Social Psychological Factors

    2023. Joanna Lindström.

    Avhandling (Dok)

    Violent extremism is a costly, global problem, yet research has yet to come to a consensus on the psychological underpinnings of violent extremism. The aim of this dissertation was to contribute to a more nuanced understanding of the psychological underpinnings of violent extremism and group-based violence by (1): moving beyond the traditional focus on disadvantaged groups, Islamist extremism, and first-hand experience of victimisation or disadvantage; (2): moving past the long-standing person-situation dichotomy; and (3) attempting to integrate the role of personality and social psychological factors in susceptibility to violent extremism.

    In Study I we tested a social psychological model of Islamist extremism amongst Muslims living in the West, and Muslims living in countries which have first-hand experience of Western military intervention. We found that the model applies across contexts, suggesting that a sense of muslim identity based on a sense of victimisation, cuts across borders, and victimisation can be experienced vicariously.

    In Study II I found that both personality (honesty-humility) and team identification predict violent intentions amongst soccer supporters, and that collective narcissism partially mediated these associations. 

    Study III identified common personality and social psychological predictors of group-based violence across three studies sampling from Black Lives Matters supporters, an immigration-critical group (Swedes), and soccer supporters. Across all contexts, with group-based relative deprivation positively and honesty-humility negatively predicting support for violence. Further, amongst BLM supporters and the immigration-critical group, emotionality negatively predicted support for violence, violent intentions, and self-reported aggression/violence. 

    In Study IV I predicted that modesty would be negatively associated with group-based relative deprivation amongst members of advantaged but not disadvantaged groups. Across two studies amongst White and Black Americans, and amongst men and women, I found that modesty interacted with group membership. Specifically, modesty was negatively related to group-based relative deprivation amongst White Americans but not Black Americans, and amongst men, but not women. An implication of these findings is that individuals espousing the rhetoric of far-right and men’s right’s movements, are low in modesty, predisposing them to feel a greater sense of entitlement, and hence violation of entitlement.

    Overall, the findings across these studies suggest that both personality and social psychological variables need to be considered when examining why individuals endorse violent extremism. Furthermore, the findings demonstrate that there are common personality and social psychological factors underpinning different forms of group-based violence, including identity processes, feelings of group-based disadvantage and injustice, and personality characterised by low honesty-humility and emotionality.

    Furthermore, feelings of injustice and group-based relative deprivation can be experienced in the absence of direct experience of victimisation, in non-political contexts, and even when one belongs to a structurally advantaged group. Although many groups perceive that their group is disadvantaged relative to other groups, personality (e.g., low modesty) may predispose members of structurally advantaged groups to perceive that their group is not getting what they are entitled to.

  • Who endorses group-based violence?

    2023. Joanna Lindström (et al.). Group Processes & Intergroup Relations

    Artikel

    Collective action is often equated with progressive politics, but are there aspects of group mobilisations that generalise across contexts? We examine general social and personality psychological factors behind endorsement of group-based violence across different types of violent group mobilisation. Specifically, we focus on the endorsement of group-based violence amongst supporters of the Black Lives Matter (BLM) movement (N = 394), an immigration-critical group (N = 252), and soccer supporters (N = 445). Across three preregistered studies, we tested an integrative model including personality and social psychological factors. Several effects were consistent across all three contexts, with group-based relative deprivation positively, and honesty-humility negatively, predicting support for violence. Further, amongst BLM supporters and the immigration-critical group, emotionality negatively predicted support for violence, violent intentions, and self-reported aggression/violence. Overall, our results suggest that individuals who endorse violence in different contexts have some psychological factors in common.

  • Low modesty linked to feeling deprived within advantaged (but not disadvantaged) groups

    2023. Joanna Lindström, Robin Bergh, Nazar Akrami. Journal of Research in Personality 103

    Artikel

    There is growing recognition that members of structurally advantaged groups experience group-based relative deprivation. We consider the idea that personality may explain these “entitlement-based” feelings of deprivation. Specifically, we predicted that modesty would be negatively associated with group-based relative deprivation among members of advantaged groups, but not amongst disadvantaged groups. Two studies focusing on White and Black Americans (N = 334), and Men and Women (N = 309) showed that modesty interacted with group membership. Modesty was negatively related to group-based relative deprivation amongst White Americans and men, but not amongst Black Americans and women. The findings help explain why some individuals espouse rhetoric that their group is being disfavored, even when group statistics and history suggest otherwise.

  • Suicide Terrorism

    2020. Joanna Lindström, Torun Lindholm. Encyclopedia of Evolutionary Psychological Science

    Kapitel

    Suicide terrorism, which is usually tied to a non-state organization, is the act of sacrificing one’s life in an effort to harm, damage, or destroy members of an out-group, for political and social objectives.

  • The role of Muslim identity in predicting violent behavioural intentions to defend Muslims

    2020. Milan Obaidi (et al.). Group Processes & Intergroup Relations 23 (8), 1267-1282

    Artikel

    A sense of shared Muslim suffering seems to play a key role in uniting Muslims around the world. Therefore, in the current paper we hypothesized that the social psychological underpinnings of Islamist extremism would be similar for Muslims living in the West and Muslims living in countries with prolonged and ongoing exposure to Western-led military interventions. Across 4 studies among Muslims in Pakistan and Afghanistan (Ns = 425, 402, and 127) and Muslims living in 20 Western countries (N = 366), we examined a path model in which group-based anger mediated the link between Muslim identification, perceived injustice of Western military and foreign policy, and violent behaviour intentions. Our results indicate that regardless of whether Muslims live in places with prolonged and ongoing experience of Western military interventions or not, the social psychological factors predicting violent Islamist extremism appear to be similar. We discuss implications for future theory and research.

  • Personality and Team Identification Predict Violent Intentions Among Soccer Supporters

    2021. Joanna Lindström. Frontiers in Sports and Active Living 3

    Artikel

    Soccer supporter violence remains a persistent global problem. The majority of research examining the psychological underpinnings of soccer supporter violence have focused primarily on the role of team identification. Relatively little research has examined the role of basic personality traits and willingness to engage in violence amongst soccer supporters. In a study amongst Swedish soccer supporters (N = 247), we examined whether honesty-humility and team identification predict violent behavioral intentions; examining if collective narcissism mediates these associations. Honesty-humility negatively predicted violent intentions, and team identification predicted violent intentions. Collective narcissism partially mediated these associations. When both Honesty-humility and team identification are accounted for though, collective narcissism did not predict violent intentions. Such findings have implications for the design of violence prevention interventions amongst soccer supporters.

  • Effects of daily L-dopa administration on learning and brain structure in older adults undergoing cognitive training

    2020. Alexander V. Lebedev (et al.). Scientific Reports 10

    Artikel

    Cognitive aging creates major individual and societal burden, motivating search for treatment and preventive care strategies. Behavioural interventions can improve cognitive performance in older age, but effects are small. Basic research has implicated dopaminergic signalling in plasticity. We investigated whether supplementation with the dopamine-precursor L-dopa improves effects of cognitive training on performance. Sixty-three participants for this randomised, parallel-group, double-blind, placebo-controlled trial were recruited via newspaper advertisements. Inclusion criteria were: age of 65–75 years, Mini-Mental State Examination score >25, absence of serious medical conditions. Eligible subjects were randomly allocated to either receive 100/25 mg L-dopa/benserazide (n = 32) or placebo (n = 31) prior to each of twenty cognitive training sessions administered during a four-week period. Participants and staff were blinded to group assignment. Primary outcomes were latent variables of spatial and verbal fluid intelligence. Compared to the placebo group, subjects receiving L-dopa improved less in spatial intelligence (−0.267 SDs; 95%CI [−0.498, −0.036]; p = 0.024). Change in verbal intelligence did not significantly differ between the groups (−0.081 SDs, 95%CI [−0.242, 0.080]; p = 0.323). Subjects receiving L-dopa also progressed slower through the training and the groups displayed differential volumetric changes in the midbrain. No statistically significant differences were found for the secondary cognitive outcomes. Adverse events occurred for 10 (31%) and 7 (23%) participants in the active and control groups, correspondingly. The results speak against early pharmacological interventions in older healthy adults to improve broader cognitive functions by targeting the dopaminergic system and provide no support for learning-enhancing properties of L-dopa supplements in the healthy elderly. The findings warrant closer investigation about the cognitive effects of early dopamine-replacement therapy in neurological disorders. This trial was preregistered at the European Clinical Trial Registry, EudraCT#2016-000891-54 (2016-10-05).

  • Smell-Based Memory Training

    2020. Jonas K. Olofsson (et al.). Chemical Senses 45 (7), 593-600

    Artikel

    Human and non-human animal research converge to suggest that the sense of smell, olfaction, has a high level of plasticity and is intimately associated with visual-spatial orientation and memory encoding networks. We investigated whether olfactory memory (OM) training would lead to transfer to an untrained visual memory (VM) task, as well as untrained olfactory tasks. We devised a memory intervention to compare transfer effects generated by olfactory and non-olfactory (visual) memory training. Adult participants were randomly assigned to daily memory training for about 40 days with either olfactory or visual tasks that had a similar difficulty level. Results showed that while visual training did not produce transfer to the OM task, olfactory training produced transfer to the untrained VM task. Olfactory training also improved participants’ performance on odor discrimination and naming tasks, such that they reached the same performance level as a high-performing group of wine professionals. Our results indicate that the olfactory system is highly responsive to training, and we speculate that the sense of smell may facilitate transfer of learning to other sensory domains. Further research is however needed in order to replicate and extend our findings.

  • Obesity and emotional well-being in adolescents

    2016. Kelly Gall (et al.). Obesity 24 (4), 837-842

    Artikel

    ObjectiveWeak or inconsistent association between obesity and impairment in emotional well-being in population-based samples has led to efforts to identify mediating variables. This study examined the relative importance of body dissatisfaction (BD), loss of control (LOC) eating, and self-rated health (SRH) in mediating the association between obesity and impairment in emotional well-being in a school-based sample of adolescents (boys, n=437; girls, n=950). MethodsModerated mediation analysis was employed to assess the relative importance of the putative mediating variables and moderation of mediation effects by sex following the methods suggested by Hayes and coworkers. ResultsBD and SRH, but not LOC eating, were found to mediate the association between obesity and impairment in emotional well-being. Stronger mediation effects were observed for BD than for SRH. None of these results was moderated by sex. ConclusionsThe findings suggest that it may be important to target BD in obesity prevention and treatment programs in order to reduce the adverse impact of excess body weight on young people's emotional well-being.
