The evolution of complex signals may be favoured by hidden preferences or pre-existing sensory biases. Females of two species of grey treefrogs (Hyla chrysoscelis and Hyla versicolor) were tested with combinations of a conspecific advertisement call and acoustic appendages. Appendages consisted of aggressive calls and segments of advertisement calls from conspecific males and males of three oth...

Opt-in mobile advertisement platform services are increasingly popular. In this paper, we explore how repeated ad exposure and physical avoidance influence consumers’ responses to mobile ads. Using a unique panel-level data of 1,193,131 million users from Cash Slide, a Korean mobile advertising platform, we find that 1) repeated ad exposure and physical avoidance has a negative impact on a cons...

Two studies tested the notion that the confidence consumers have in their cognitive responses to an ad can increase or decrease the favorability of product attitudes. Increasing confidence in positive thoughts enhanced advertisement effectiveness. Increasing confidence in negative thoughts reduced advertisement effectiveness. These self-validation effects occurred regardless of the type of prod...

OBJECTIVE Assess the effect of counter-advertisements on parents' appraisals of unhealthy foods featuring front-of-package promotions (FOPPs). DESIGN A 2 × 2 × 5 between-subjects Web-based experiment. Parents were randomly shown an advertisement (counter-advertisement challenging FOPP/control advertisement) and then a pair of food products from the same category: an unhealthy product featurin...

Existing theory predicts that male signalling can be an unreliable indicator of paternal care, but assumes that males with high levels of mating success can have high current reproductive success, without providing any parental care. As a result, this theory does not hold for the many species where offspring survival depends on male parental care. We modelled male allocation of resources betwee...

Traditionally, psychiatry has been defined and practiced as a branch of medicine focused on the diagnosis and treatment of mental illnesses. Based on growing empirical evidence, we believe that this definition warrants expansion to include the concept of positive psychiatry. In the present article, we provide a critical overview of this emerging field and a select review of relevant scientific ...
