Social Media Influencers' Misinformation about COVID-19: A Multiple-Exposure Experiment.
No full textIn this project, we investigate how social media influencers impact young people’s opinion formation regarding COVID-19. During the COVID-19 pandemic, social media influencers who usually post about traveling, fashion or lifestyle have repeatedly stated their opinions about the COVID-19 measures. Since they usually do not have expertise in the areas of health or disease prevention, they may misinform their followers about these topics, which may have severe consequences like less compliance with the COVID-19 measures or infecting oneself or others with the virus. Yet, their followers may be highly susceptible to this information, because they trust influencers or have developed parasocial relationships with them. For this purpose, we conduct a multiple-exposure online experiment, in which young women are exposed to a female social media influencer's news feed across four time points after completing a pre-questionnaire. At the fifth exposure time, they are randomly assigned to a condition in which the social media influencer states misinformation about COVID-19 or a control condition in which correct information is presented. As dependent variables, we assess attitudes and beliefs toward COVID-19 and confidence in information about COVID-19. As moderators, we investigate the degree of parasocial relationships with influencers, influencers' perceived credibility and trust in their advice. Additionally, we test whether individuals' literacy regarding the media channel, the source, and the information prevent them from falling victim to the misinformation
The Kindness Questionnaire
No full textHow kind are people to family, friends, colleagues and strangers? Are their decisions consistent – guided by the underlying logic of the costs and benefits of kindness? Previous research using monetary ‘welfare trade-off ratios’ (WTRs) has shown, for example, that people are kinder to family than to friends, and kinder to friends than to strangers, but still exhibit a substantial degree of kindness even to strangers (WTR=0.3; Tooby et al., 2008). Here we replicate and extend that work by developing a new measure of WTR – The Kindness Questionnaire – that uses acts of kindness that have been previously normed for their perceived costs and benefits

Scented Colours: The Influence of Product-Colour Congruity in the Netherlands and Bulgaria on Appreciation, Intentions and Attitudes
No full textThere is evidence that the colour of products triggers the interest of consumers through certain smell associations because there are instances when the medium does not allow to smell a product (e.g., when the product is sealed, or online when purchasing a product). As the global pandemic has changed our lives and how we purchase products, the colour of a product becomes even more important in online mediums. Therefore, marketers should understand how to place their products online (specifically on social media as a promoted post) to encourage positive attitude and high purchase intention. The study will be conducted between Dutch and Bulgarian participants. The proposed research question is, To what extent does product-colour congruence affect odour appreciation, purchase intention and attitudes towards a product across Dutch and Bulgarian participants
Attitude generalization: atgn15
No full textThe goal of this project is to examine the relative effect of information about an individual member of a social group, in comparison to the information about the other individuals in the same group on the automatic and deliberate evaluation of the individuals. Specifically, we examine the evaluation of group members that behave differently than the majority of their group (i.e., the evaluation of atypical group members)
Categorizing Features as Biological, Behavioral, Social, or Teleological
No full textThe main purpose of this study is to have people categorize features so that we can use them in developing materials for subsequent experiments. Participants will be given 42 different features (e.g., "has hair", "follows dominant group member") for different imaginary things (e.g., "a Zorp", "a Xen") that they come across while they are on a new uninhabited place. For each feature, they will decide whether it should be categorized as: biology, behavior, social, or purpose. Top items from each of the four categories will be used in developing subsequent experimental materials
Task cue influences on priming: Manipulations of task set dominance. Letters R and B as task cues.
No full textParticipants will perform two trial types in randomized, intermixed order: induction task trials and task-cue only trials. In induction task trials, they have to perform a semantic or perceptual decision on pictures according to a task cue (indicating the semantic or the perceptual decision). In task-cue only trials the task cues are presented without following picture, i.e. no decision has to be made. In both trial types, a masked lexical decision task (LDT) follows. Previous work showed that task sets are also activated if no task has to performed, i.e. they are also activated in task-cue only trials.
The focus of this research rests on task-cue only trials. In one condition, task sets are considered as strong, when task cues and decision categories are congruent. In the other condition, task sets are considered as weak due to an incongruence between task cues and decision categories. We manipulate congruence of task cues and decision categories by manipulating the relation of task cue and decision category. In the strong condition, the task cue “R” indicates the perceptual decision (“Rund”-decision; engl.: round) and the task cue “B” indicates the semantic decision (“Belebt”-decision; engl.: living). Task cue assignment to decision categories is reversed in the weak condition. As a consequence, there is no relation between task cues and the first letter of the related decision category in the weak condition
Does emotional dysregulation explain the association between ADHD and emotional problems?
No full textAttention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, affecting between 5 and 7% of children on average (Barkley, 2014). The main symptoms of ADHD can be categorised into two types of behavioural problems: inattentiveness and hyperactivity/impulsiveness (Barkley, 2014). Recently, it has been argued that another core symptom of ADHD is emotional dysregulation, here defined as emotional expressions and experiences that are excessive in relation to social norms and developmental stage are context-inappropriate; rapid, poorly controlled shifts in emotion (‘lability’); and the anomalous allocation of attention and to emotional stimuli (Shaw et al., 2014). The prevalence of moderate emotional dysregulation co-occurring with ADHD is around 25% and severe emotional dysregulation co-occurring with ADHD is 50% (Shaw et al,. 2014 ; Sobanski et al,. 2010). The present study investigates the role of emotional dysregulation in explaining the association between ADHD and emotional problems. We hypothesize the following: (1) there is an association between ADHD and emotional problems in children aged 5, and, (2) this association is partially mediated by emotional dysregulation children aged 5. We use data from the UK Millennium Cohort Study age 5 wave (MCS3 sweep) to investigate this (Connelly & Platt, 2014)
