Database_2018_Sexting, Cyberbullying and Emerging Online Risks
No full textDatabase of 7,197 secondary school students (51.9% boys, 48.1% girls) aged 7-19 (M = 12.89, SD = 1.71) on Sexting, Cyberbullying and Emerging Online Risks
Parental involvement and well-being in youth competitive athletes
No full textThis project investigated the relationship between parental involvement in sports and athletes' overall well-being, with a specific focus on two mediators: the satisfaction and frustration of basic psychological needs. The sample comprised 298 xxx competitive athletes, aged 16 to 26, from various sports disciplines and performance levels. Participants completed an online questionnaire measuring perceived parental involvement (PISQ), basic psychological needs (BPNSF), and well-being (MHC-SF)
Do dogs follow Weber’s Law? The role of ratio and difference in quantity preference
No full textWeber's Law states that the ability to distinguish different stimuli depends on the relative magnitudes of those stimuli. When applied to quantity judgments, this means that the numerical ratio between two quantities (small amount / large amount) will underlie the ability to distinguish the quantities. Ratio-dependent quantification is a hallmark of Weber's Law that has been demonstrated across a range of species, including dogs. However, other factors such as numerical difference (large amount - small amount) are confounded with ratio but would not support Weber's Law. Most work on dog quantification abilities has only considered ratio and not difference. Here, we offer dogs a food quantity preference task where we varied both difference and ratio in quantity pairs to investigate which of these factors influences preferences. To address this, dogs could choose to eat one of two plates of food with different quantities of treats on them. We found that, when analyzed separately, both difference and ratio predicted whether the dogs chose the larger quantity of treats. However, when analyzed together, only difference predicted choice when controlling for ratio. In addition, we applied our analysis to data from two previously published studies and corroborated our findings. The results do not support the ratio-dependence required for Weber's Law, raising questions about its importance for quantity preference tasks in dogs

The Roles of N300 and N400 in Scene Processing
No full textExamining the role of N300 and N400 ERP components by presenting scenes in which a target object is manipulated in two ways: congruent vs. incongruent object in a scene, and intact vs. scrambled object in a scene
Study 3a: convergent and divergent validity
No full textThe aim of this study is to validate a scale about threat of older people based on Intergroup Threat Theory (ITT; Stephan & Stephan, 2017). To the best of our knowledge, no such measure exists in the ITT literature. We will use the BFAS (DeYoung et al., 2007) to assess the convergent and divergent validity of our scale of threat of older people. Specifically, convergent validity will be tested using the Withdrawal aspect of the Neuroticism factor of BFAS as a criterion and divergent validity will be tested using the Volatility aspect of the Neuroticism factor of BFAS as a criterion
