This study aims to examine the associations between personality traits, using the big-5 personality model (Costa & McCrae, 1992), and compliance with pandemic measures (e.g. handwashing), and perceived risk of the pandemic to the individual, in a representative sample of the adult Norwegian population.

 

Several previous studies have examined associations between personality and adherence to medical advice using measures administered at the same point in time the during COVID-19 pandemic (e.g. Götz et al., 2021), however the dataset the current investigators plan to use assessed personality one year prior to the pandemic (May/June 2019) and the risk and compliance measures four months into the pandemic (August/September 2020). 
 
Here, Sætrevik et al. (2024) make a number of hypotheses, including that conscientiousness, agreeableness, openness and neuroticism will be positively associated with compliance; extraversion will be negatively associated with compliance; extraversion and openness will be negatively associated with perceived risk; and finally, neuroticism will be positively associated with perceived risk. They plan to test their hypotheses using linear regression analyses.
 
Importantly, given the topic, the data for this study already exists and some response distributions of the compliance and risk measures have been examined. However, the authors have yet to link the data on personality to the data on compliance and risk, which is the focus of their hypotheses.  
 
The findings from this study will help us to understand the personality characteristics associated with infection control measures and individual risk perceptions of viral illnesses during a pandemic.

A poor diet has severe detrimental health effects, and attempts to reduce caloric intake often prove unsuccessful. Unhealthy foods, high in fat, sugar, and salt tend to be highly appetitive, and can undermine individuals’ ability to refrain themselves from consuming them. Computerized cognitive retraining techniques have shown promise in curbing the intake of unhealthy foods and promoting weight loss. However, in real-world scenarios, adherence to such retraining programs can be suboptimal, potentially diminishing their effectiveness.

 

In the present study, Maclellan et al. (2024) aimed to investigate whether the incorporation of gamified elements, transforming the cognitive retraining task into a game-like experience, can enhance adherence and overall intervention effectiveness by boosting engagement and motivation.

 

Upon testing the main hypotheses, the authors found mostly non-significant effects of adding gamified elements to adherence, motivation, or effectiveness of food response inhibition training programs. These results hold high relevance, as indeed there has been a push in introducing gamified elements to cognitive retraining programs. These findings should guide future developments in the field of cognitive retraining.

The cardinality principle (CP) is a key concept in numerical cognition, which children typically acquire by the age of five. This is the understanding that each number in a counted sequence refers to a specific set of items, and that the final number represents the total size of the set. Here, Ivanova and colleagues (2024) propose an experiment to study the changes in neural activity that accompany the acquisition of this concept, focusing on activity within the parietal lobes as measured by functional near-infrared spectroscopy (fNIRS).

 

Typically-developing children aged from 2 years 9 months to 4 years 9 months will be assessed for their ability to give a specific number of balls from a pile: those who can give five or more correctly will be classified as CP-knowers, and those who can only give lower set sizes will be classified as subset-knowers. All children will then perform an auditory number word adaptation task while undergoing fNIRS. The adaptation task involves hearing the number word ‘two’ repeated, interspersed with deviant number words (‘four’ or ‘eight’) or a non-number word (‘rin’). The experimental hypotheses are that left parietal activations and bilateral parietal functional connectivity will be differentially greater for number than non-number deviants amongst CP-knowers than amongst subset-knowers. Each hypothesis will be tested by sequential Bayes factor analysis, with a minimum of 25 and a maximum of 46 participants per group, providing high sensitivity to detect a smallest effect size of d = .35. This study aims to provide insights into the neural underpinnings of the CP, informing theoretical models of symbolic knowledge acquisition.

The link between climate change and health is becoming increasingly clear, and problematic (IPCC, 2023). While most agree that climate change is a problem (Vlasceanu et al., 2024) and evidence is starting to emerge that individual's wellbeing can benefit from engaging in proenvironmental behaviour (Prinzing, 2023), there is little robust longitudinal evidence available to make causal claims about the complex and inter-related nature of these types of effects.

 

In their proposed study, Major-Smith et al. (2024) use the Avon Longitudinal Study of Parents and Children to explore whether climate concern has a causal impact upon mental health. Strategic use of this pre-existing data allows consideration of both confounding bias and reverse causality to provide more rigorous evidence for this causal effect. The second research question (whether climate action moderates this relationship) is of both personal and professional interest, as someone who struggles with climate anxiety, and plants hundred of trees annually to try and mitigate the dread. Capable of exploring the potential for individual-level climate action to have a double effect - directly help with climate change mitigation and also an individuals' mental health, the proposed research is a rewarding and insightful line of inquiry in a domain desperate for a more rapid and rigorous evidence-base.

When people are less-well-known to us, it can impact how we treat them. People outside our communities may feel more anonymous or de-personalized to us, and this could impact the empathy we feel for them. Indeed, past research shows that people seem to care more for those who are who are identified to us, especially when they are victims of a crime (Small & Loewenstein, 2003). In addition, past research also shows that anonymizing victims can influence criminal behavior (Walters, 2022).  Thus, social cognitive factors related to anonymity appear to affect both positive feelings (engaging in empathy) and negative activities (criminal activity) related to victims. It seems likely that anonymity can also affect how people judge criminals themselves.

 

This paper by Blanke and Twardawski (2024) examines how even minor identifying features can make individuals react differently to a perpetrator of a crime. A picture or name (information that may appear in the press) may impact how people perceive criminals in terms of punishment, empathy, outrage, and blame.

 

How people respond to anonymous or identified criminals may depend on whether the impact of the crime on the victim is made salient. Similar to the Black Sheep Effect (Marques & Paez,1994), the current paper expects that people who identify with victims are expected to punish a perpetrator more when the perpetrator’s name and image are known. This is similar to the case with an ingroup member in The Black Sheep Effect, where ingroup members are punished more for transgressions than outgroup members. For people who view the situation as a third party (and are thus less connected to the victim), an identified perpetrator is expected to lead to less punishment (and also less outrage and blame, and more empathy).

 

The current study focuses on pickpocketing since it is a crime that can be committed without identifying oneself to the victim. Future research should examine how the type of event impacts judgments, especially given the stigma of being a victim of some crimes. Littering and other minor violations may be seen as understandable when you see someone as a person, rather than a anonymous, impersonal criminal.  On the other hand, there can be stigma to being a victim in some cases, such as the case of sexual harassment, where, research shows, perpetrators are judged more positively if they are identified, and victims, especially women, are judged more negatively if they are identified (Barak-Corren & Lewinsohn-Zamir, 2019).

 

People around the world engage in moral and legal transgressions, and if our judgments of them are influenced by minor features such as a photo or name, we should take action to treat people more fairly. This research will help to determine if people are influenced by these factors.
