Objective: We investigated the relationship between personal relative deprivation (PRD)-resentment from the belief that one is worse off than people who are similar to oneself-and locus of control.

Background: Research has yet to comprehensively investigate whether PRD is associated with a tendency to favor external (vs. internal) explanations for self- and other-relevant outcomes.

Individual differences in Theory of Mind (ToM)-the ability to understand the mental states of others-are theorised to be predicted by socio-demographic and political factors. However, inconsistent findings on the relationships between various socio-demographic predictors and ToM, as well as a paucity of research on political predictors of ToM, have left a gap in the literature. Using a recently validated self-report measure of ToM in a large sample (N = 4202) we investigated the unique contributions of age, sex, socio-economic status, and political beliefs to ToM in adults.

It is often suggested that supporting autistic people to identify and use their strengths will lead to positive outcomes. However, little research has explored if this is true. To date, no research has explored whether autistic people already have knowledge of and use their strengths, nor whether increased strengths knowledge and use is linked to good outcomes, such as a better quality of life, well-being and improved mental health.

Autism and anxiety are thought to be related to extreme demand avoidance (EDA), which is characterised by intense avoidance of everyday demands. However, the relative importance of autism and anxiety to EDA has yet to be investigated, and little is known about EDA in adulthood. We conducted two online survey studies (Ns = 267 and 549) with adults in the general population to establish the relative importance of autistic traits and anxiety as predictors of demand avoidance, using dominance analysis.

Following the popularity of dual process models in social and cognitive psychology, there is major interest in the possibility that autism is associated with impaired "fast" intuitive thinking but enhanced "slow" or "rational" deliberative thinking. If correct, this has great potential to help understand various strengths and difficulties characteristic of autism. Previous empirical investigations of this phenomenon, however, are marred by concerns about the measurement of intuitive and deliberative processing, as well as broader problems in clinical psychological science (e.

Personal relative deprivation (PRD; the belief that one is worse off than other people who are similar to oneself) is associated with a reduced willingness to delay gratification, lower prosociality, and increased materialism. These results suggest that PRD may play a role in shaping people's willingness to act to protect the natural environment. We report 3 studies that investigate a possible link between PRD and pro-environmental intentions (ENV).

Mentalising, also known as "Theory of Mind", is the ability to understand and infer the cognitions of others, such as their perceptions, intentions, and beliefs. Although several tools have been designed to measure mentalising in adults, there exist methodological and practical limitations. Many of the existing measures conflate mentalising with similar constructs (e.

The autonomic nervous system (ANS) is responsible for the functioning of the heart, bladder, pupils and several other bodily functions. Therefore, when the ANS functions abnormally, individuals can experience a number of physical symptoms, including dizziness, abnormal sweating and digestive difficulties. Currently, it is unclear if autistic adults experience ANS dysfunction.

Research during the 1960s found that observers could be moved enough by an innocent victim's suffering to derogate their character. However, recent research has produced inconsistent evidence for this effect. We conducted the first meta-analysis ( = 55) of the experimental literature on the victim derogation effect to test the hypothesis that it varies as a function of the emotional impactfulness of the context for observers.

It has been proposed that atypical empathy in autism spectrum disorder (ASD) is due to co-occurring alexithymia. However, difficulties measuring empathy and statistical issues in previous research raise questions about the role of alexithymia in empathic processing in ASD. Addressing these issues, we compared the associations of trait alexithymia and autism with empathy in large samples from the general population.

We examined the causal order of relationships between rape myth acceptance (RMA), victim blaming, and memory reconstruction. In Study 1, RMA-congruent memory (or alternatively, victim blaming) mediated the relationship between RMA and victim blaming (memory reconstruction). In Study 2, similar relationships emerged between RMA, victim blaming, and memory reconstruction.

The extent to which an individual believes in free will is associated with a number of positive life outcomes, including their own subjective well-being. However, it is not known whether the belief that one has free will is uniquely associated with subjective well-being over and above potential confounding variables. We examined a sense of personal control as one such confound-specifically, whether the association between free will belief (FWB) and subjective well-being is based, in part, on the degree to which an individual feels a sense of personal control over their life.

The current research developed and validated a Korean-translated version of the Personal Relative Deprivation Scale (PRDS). The PRDS measures individual differences in people's tendencies to feel resentful about what they have compared to what other people like them have. Across 2 studies, Exploratory Factor Analyses revealed that the two reverse-worded items from the original PRDS did not load onto the primary factor for the Korean-translated PRDS.

We propose that personal relative deprivation (PRD)-the belief that one is worse off than similar others-plays a key role in the link between social class and prosociality. Across multiple samples and measures (total = 2,233), people higher in PRD were less inclined to help others. When considered in isolation, neither objective nor subjective socioeconomic status (SES) was meaningfully associated with prosociality.

Drawing on just-world theory and research into the suppression and justification of prejudice, we propose that the use of relative compared with absolute measures of an innocent victim's character enables observers to derogate the victim without transparently violating social norms or values proscribing derogation. In Study 1, we found that positive feelings expressed toward victims mirrored social norms proscribing negative reactions toward them. In Studies 2a, 2b, and 3, innocent victims were evaluated more negatively when ratings were made using relative (i.

First impressions based on facial appearance predict many important social outcomes. We investigated whether such impressions also influence the communication of scientific findings to lay audiences, a process that shapes public beliefs, opinion, and policy. First, we investigated the traits that engender interest in a scientist's work, and those that create the impression of a "good scientist" who does high-quality research.

Temporal binding refers to the compression of the perceived time interval between voluntary actions and their sensory consequences. Research suggests that the emotional content of an action outcome can modulate the effects of temporal binding. We attempted to conceptually replicate these findings using a time interval estimation task and different emotionally-valenced action outcomes (Experiments 1 and 2) than used in previous research.

Across five studies, we found consistent evidence for the idea that personal relative deprivation (PRD), which refers to resentment stemming from the belief that one is deprived of deserved outcomes compared to others, uniquely contributes to materialism. In Study 1, self-reports of PRD positively predicted materialistic values over and above socioeconomic status, personal power, self-esteem, and emotional uncertainty. The experience of PRD starts with social comparison, and Studies 2 and 3 found that PRD mediated the positive relation between a tendency to make social comparisons of abilities and materialism.

Lower subjective socioeconomic status (SSS) and higher personal relative deprivation (PRD) relate to poorer health. Both constructs concern people's perceived relative social position, but they differ in their emphasis on the reference groups people use to determine their comparative disadvantage (national population vs. similar others) and the importance of resentment that may arise from such adverse comparisons.

One psychosocial factor that has been identified to motivate gambling is personal relative deprivation (PRD), which refers to resentment stemming from the belief that one is deprived of a desired and deserved outcome compared to some referent. Although several lines of evidence point to a positive association between PRD and the urge to gamble, the factors that might moderate this relation have yet to be investigated. Through a quantitative research synthesis, we sought to test (a) the overall relation between PRD and gambling urges among people reporting recent gambling experience, and (b) whether this relation is moderated by problem gambling severity.

People can perceive misfortunes as caused by previous bad deeds (immanent justice reasoning) or resulting in ultimate compensation (ultimate justice reasoning). Across two studies, we investigated the relation between these types of justice reasoning and identified the processes (perceptions of deservingness) that underlie them for both others (Study 1) and the self (Study 2). Study 1 demonstrated that observers engaged in more ultimate (vs.

Previous research suggests that individuals from countries that adopt an adversarial legal system, such as Canada or United Kingdom, mentally associate "law" more strongly with concepts related to competition than concepts related to cooperation. We examined whether people from a country with a non-adversarial legal system show similar mental associations. Participants from Spain and the UK completed a Single-Category Implicit Association Test.

Drawing on theorizing and research suggesting that people are motivated to view their world as an orderly and predictable place in which people get what they deserve, the authors proposed that (a) random and uncontrollable bad outcomes will lower self-esteem and (b) this, in turn, will lead to the adoption of self-defeating beliefs and behaviors. Four experiments demonstrated that participants who experienced or recalled bad (vs. good) breaks devalued their self-esteem (Studies 1a and 1b), and that decrements in self-esteem (whether arrived at through misfortune or failure experience) increase beliefs about deserving bad outcomes (Studies 1a, 1b, 2a, 2b).
