It is likely that a large proportion of people who purport to believe fake news really do, but this proportion might be significantly smaller than thought; assertion of belief is inflated, we suggest, by insincere report

Abstract: In this chapter, we provide a necessarily brief and partial survey of recent work in the cognitive sciences directly on or closely related to the psychology of fake news, in particular fake news in the political domain. We focus on whether and why people believe fake news. While we argue that it is likely that a large proportion of people who purport to believe fake news really do, we provide evidence that this proportion might be significantly smaller than is usually thought (and smaller than is suggested by surveys). Assertion of belief is inflated, we suggest, by insincere report, whether to express support for one side of political debate or simply for fun. It is also inflated by the use of motivated inference of one sort or another, which lead respondents to report believing things about which they had no opinion prior to being probed. We then turn to rival accounts that aim to explain why people believe in fake news when they do. While partisan explanations, turning on motivated reasoning, are probably best known, we show they face serious challenges from accounts that explain belief by reference to analytic thinking.

Summary: A simple test taken by millions of people reveals that virtually everybody has implicit biases that they are unaware of and that may clash with their explicit beliefs. From policing to scientific publishing, all activities that deal with people are at risk of making wrong decisions due to bias. Raising awareness is the first step towards improving the outcomes.

Abstract: This paper describes evidence suggesting that science curiosity counteracts politically biased information processing. This finding is in tension with two bodies of research. The first casts doubt on the existence of “curiosity” as a measurable disposition. The other suggests that individual differences in cognition related to science comprehension - of which science curiosity, if it exists, would presumably be one - do not mitigate politically biased information processing but instead aggravate it. The paper describes the scale-development strategy employed to overcome the problems associated with measuring science curiosity. It also reports data, observational and experimental, showing that science curiosity promotes open-minded engagement with information that is contrary to individuals’ political predispositions. We conclude by identifying a series of concrete research questions posed by these results.

In the self-experienced (vs. other-experienced) jealousy condition, activity was greater, inter alia, in the fronto-striato-thalamo-frontal circuit, a network implicated in habit formation & obsessive-compulsive disorder

Abstract: The present brain-imaging study assessed neural correlates of romantic jealousy in women who had suffered real infidelity by their partner. We predicted to find activation across different brain structures associated with the processing of negative emotions and cognitive processes as well as obsessive-compulsive behavior. FMRI scans were administered while participants listened to descriptions of their own or another person’s experience of infidelity and jealousy, or to nonsense words. In the self-experienced (vs. other-experienced) jealousy condition, activity was greater in areas commonly associated with the interaction between different negative emotions (i.e., insula, anterior cingulate cortex, medial prefrontal cortex) such as fear, anger, sadness and cognitive processes like rumination. Enhanced activity was also found in the fronto-striato-thalamo-frontal circuit, a network implicated in habit formation and obsessive-compulsive disorder. Activation in the above networks was not enhanced when participants listened to other-experienced infidelity reports, as indicated by comparisons with the neutral condition. We discuss implications for the understanding and treatment of jealousy.

Fear of receiving compassion from others, and related fears, are potentially important factors in the persistence of depression, stress disorders, and eating disorders; they may play a role in anxiety and related difficulties

Scared of compassion: Fear of compassion in anxiety, mood, and non‐clinical groups. Olivia A. Merritt, Christine L. Purdon. British Journal of Clinical Psychology, Volume 59 Issue 3 (September 2020), Pages i-iv, 277-460.

Objectives: Fear of receiving compassion from others, expressing compassion to others, and being compassionate towards oneself have been identified as potentially important factors in the persistence of depression, stress disorders, and eating disorders. There is good reason to expect that these fears may play a role in anxiety and related difficulties, but there is little available information on the extent to which they are present and associated with symptom severity.
Methods: This study compared the severity of the three fears of compassion (receiving, expressing to others, and showing to oneself) in those with a principal diagnosis of depression (n = 34), obsessive–compulsive disorder (OCD; n = 27), social anxiety disorder (SAD; n = 91), generalized anxiety disorder (GAD, n = 43), and a control sample with no mental health difficulties (n = 212).
Results: Those with depression, OCD, SAD, and GAD exhibited greater fear of receiving compassion and fear of self‐compassion than controls, and the differences between anxious and control groups remained significant even when controlling for depressed mood. Whereas fears of compassion did not predict symptom severity over and above depressed mood in people with GAD, fear of receiving compassion uniquely predicted SAD symptom severity, and fear of expressing compassion for others uniquely predicted OCD symptom severity in those high on fear of self‐compassion.
Conclusions: Fear of compassion is higher in those with anxiety and related disorders than non‐anxious controls. Although further research is needed, clinicians may benefit from assessing fear of compassion and addressing it in treatment.
Practitioner points: Those with anxiety and related disorders may fear receiving compassion from others or expressing compassion for themselves, even when controlling for depression. It may be informative to assess for fear of compassion and incorporate discussions about these fears into treatment, as these fears may interfere with treatment progress.

Seeing the Whole Picture? Avoided Negative Affect and Processing of Others’ Suffering

Seeing the Whole Picture? Avoided Negative Affect and Processing of Others’ Suffering. Birgit Koopmann-Holm et al. Personality and Social Psychology Bulletin, February 11, 2020.

Abstract: Noticing someone’s pain is the first step to a compassionate response. While past research suggests that the degree to which people want to avoid feeling negative (“avoided negative affect”; ANA) shapes how people respond to someone’s suffering, the present research investigates whether ANA also predicts how people process others’ suffering. In two studies, using complex photographs containing negative aspects (i.e., suffering), we found that the higher people’s ANA, the fewer details of negative aspects they correctly recognized, and the fewer negative words they used in their image descriptions. However, when asked to process negative content, the higher people’s ANA, the more negatively they rated that content. In Study 3, we report cultural differences in people’s sensitivity to notice suffering in an ambiguous image. ANA mediated these cultural differences. Implications for research on compassion are discussed.

(How) Do You Regret Killing One to Save Five? Affective and Cognitive Regret Differ After Utilitarian and Deontological Decisions

(How) Do You Regret Killing One to Save Five? Affective and Cognitive Regret Differ After Utilitarian and Deontological Decisions. Jacob Goldstein-Greenwood et al. Personality and Social Psychology Bulletin, January 28, 2020.

Abstract: Sacrificial moral dilemmas, in which opting to kill one person will save multiple others, are definitionally suboptimal: Someone dies either way. Decision-makers, then, may experience regret about these decisions. Past research distinguishes affective regret, negative feelings about a decision, from cognitive regret, thoughts about how a decision might have gone differently. Classic dual-process models of moral judgment suggest that affective processing drives characteristically deontological decisions to reject outcome-maximizing harm, whereas cognitive deliberation drives characteristically utilitarian decisions to endorse outcome-maximizing harm. Consistent with this model, we found that people who made or imagined making sacrificial utilitarian judgments reliably expressed relatively more affective regret and sometimes expressed relatively less cognitive regret than those who made or imagined making deontological dilemma judgments. In other words, people who endorsed causing harm to save lives generally felt more distressed about their decision, yet less inclined to change it, than people who rejected outcome-maximizing harm.

In cognitive diagnosis models, the condensation rule reflects how latent attributes influence individuals’ observed item responses; in practice, multiple condensation rules may be involved in an item simultaneously

Zhan, Peida. 2020. “Deterministic-inputs, Noisy Mixed Modeling for Identifying Coexisting Condensation Rules.” PsyArXiv. February 12. doi:10.31234/

Abstract: In cognitive diagnosis models (CDMs), the condensation rule reflects how latent attributes influence individuals’ observed item responses. In practice, multiple condensation rules may be involved in an item simultaneously, which indicates that the contribution of required attributes to the correct item response probability follows multiple condensation rules with different proportions. To consider the coexisting condensation rules while keeping the interpretability of model parameters, this study proposed the deterministic-inputs, noisy mixed (DINMix) model. Two simulation studies were conducted to evaluate the psychometric properties of the proposed model. The results indicate that the model parameters for the DINMix model can be well recovered, and the DINMix model can accurately identify coexisting condensation rules. An empirical example was also analyzed to illustrate the applicability and advantages of the proposed model.

6. Summary and Discussion
The condensation rule describes the logical relationship between the required attributes and the item response. When an item contains coexisting condensation rules, it means that the contribution of required attributes to the correct item response probability follows multiple condensation rules with different proportions. Coexisting condensation rules reflect the complexity of cognitive processes in problem-solving. To take into account coexisting condensation rules while keeping the interpretability of model parameters, this study proposed the DINMix model. Two simulation studies were conducted to evaluate the psychometric properties of the proposed model. The simulation results indicate that (a) the model parameters for the DINMix model can be well recovered, especially in the conditions with a larger sample, longer test length, and higher item quality; (b) the DINMix model can adaptively and accurately identify coexisting condensation rules, either existing simultaneously in an item or existing separately in multiple items. An empirical example was also analyzed to illustrate the applicability and advantages of the proposed model.

As aforementioned, the DINMix model can be viewed as a constraint model from the GDINA model after some parameter transformations. Thus, the number of item parameters of the DINMix model is larger than that of the reduced models but smaller than that of the general models. For example, in the simulated condition in simulation Study 2, there were 60, 60, 60, 100, and 140 items parameters for the DINA, DINO, DINR, DINMix, and GDINA models, respectively. To explore the differences between the performance of the DINMix and GDINA models, we also used the GDINA model to conduct a simple analysis of the data in simulation Study 2, based on the GDINA package (Ma & de la Torre, 2020) in R software. The results (see Tables S4 and S5 in online supplements) indicate that the performance of the DINMix and GDINA models was almost identical in the recovery of attributes and item parameters. Specifically, the DINMix and GDINA models have almost the same diagnostic capabilities, but the former is more concise and easier to be interpreted.

The work represented in this article is an initial attempt to simultaneously consider multiple condensation rules in a single CDM. Despite promising results, some limitations still exist. First, the utilized model framework (see Equations 1 and 5) models the aberrant responses at the item level. However, in practice, such aberrant responses may occur at the attribute rather than item level, such as the noisy inputs, deterministic, ‘and’ gate model (Junker & Sijtsma, 2001). Ways to incorporate attribute-level aberrant responses into the proposed model are worthy of further research, as Equation 11 in de la Torre (2011) seems to give us a reference. Second, within-item characteristic dependency (Zhan, Jiao, Liao et al., 2019), which means that the dependency exists between the guessing and slip parameters within an item, was not considered in the proposed model. It can be incorporated into the proposed model to increase the estimation accuracy of the item parameters in a future study. Third, only the dichotomous scoring item and dichotomous attribute were modeled in the proposed model. It would be meaningful and practical to extend the current model to consider polytomous scoring items (e.g., Ma & de la Torre, 2016) and polytomous attributes (e.g., Zhan et al., 2020). Fourth, in recent years, some studies have focused on the Q-matrix validation or estimation (Chen et al., 2018; de la Torre & Chiu, 2016) and the multiple strategies for problem-solving (Ma & Guo, 2019), which are not covered in current study. Fifth, notably, the generalizability of the findings of this study is dependent upon the limitations of the design of the simulation studies, such as a fixed number of attributes and assuming the Q-matrix is correct. To further generalize these findings, a wider range of simulated conditions should be considered in future studies.
