Electrophysiological responses to conspecific odorants in Xenopus laevis show potential for chemical signaling

Plos.org 

by Heather J. Rhodes, Melanie Amo

The fully aquatic African clawed frog, Xenopus laevis, has an unusual and highly adapted nose that allows it to separately sample both airborne and waterborne stimuli. The function of the adult water nose has received little study, despite the fact that it is quite likely to receive information about conspecifics through secretions released into the water and could aid the frog in making decisions about social and reproductive behaviors. To assess the potential... Читать дальше...

Neighborhood satisfaction and reproductive status

Plos.org 

by Zachary P. Neal, Jennifer Watling Neal

Both urban planners and urban scholars have been keenly interested in identifying the characteristics associated with neighborhood satisfaction. One robust but surprising pattern is that the presence or number of children in a household has no effect on neighborhood satisfaction. To clarify this pattern, we measured the neighborhood satisfaction of a representative sample of 1,000 Michigan adults, whom we divided into six distinct reproductive statuses... Читать дальше...

Origin and diversification of free-living stick spiders of Sri Lanka including the description of four new species of Rhomphaea L. Koch, 1872 and two new species of Neospintharus Exline, 1950

by Mathura Tharmarajan, Suresh P. Benjamin

Sri Lanka is a biologically diverse South Asian island, and together with the Western Ghats (Southern India) is one of the 36 world’s most biologically diverse areas. Here, we investigated the origin and diversification of Rhomphaea and Neospintharus of Sri Lanka using sequences of three genes: mitochondrial cytochrome c oxidase I (COI) and 16S rRNA (16S); and nuclear 28S rRNA (28S). Our phylogeny included 32 taxa (30 ingroup and 2 outgroup). We... Читать дальше...

Positive fortune telling enhances men’s financial risk taking

Plos.org 

by Xiaoyue Tan, Jan-Willem van Prooijen, Paul A. M. van Lange

Fortune telling is a widespread phenomenon, yet little is known about the extent to which people are affected by it—including those who consider themselves non-believers. The present research has investigated the power of a positive fortune telling outcome (vs. neutral vs. negative) on people’s financial risk taking. In two online experiments (n1 = 252; n2 = 441), we consistently found that positive fortune telling enhanced financial risk taking particularly among men. Читать дальше...

Effects of aging on neural processing during an active listening task

Plos.org 

by Abin Kuruvilla-Mathew, Peter R. Thorne, Suzanne C. Purdy

Factors affecting successful listening in older adults and the corresponding electrophysiological signatures are not well understood. The present study investigated age-related differences in attention and temporal processing, as well as differences in the neural activity related to signal degradation during a number comparison task. Participants listened to digits presented in background babble and were tested at two levels of signal clarity, clear and degraded. Читать дальше...

Does perceived scarcity of COVID-19 vaccines increase vaccination willingness? Results of an experimental study with German respondents in times of a national vaccine shortage

Plos.org 

by Julia Schnepf

Vaccine shortage is still a major problem in many countries. But how does the vaccine shortage affect people’s willingness to be vaccinated? To test whether perceived scarcity of SARS-CoV-2 vaccines has an impact on vaccination willingness, a preregistered online experiment with N = 175 non-vaccinated German participants was conducted during a period of national vaccine shortage. Perceived vaccine scarcity was manipulated by either telling participants that SARS-CoV-2 vaccines... Читать дальше...

Eyewitness accuracy and retrieval effort: Effects of time and repetition

Plos.org 

by Philip U. Gustafsson, Torun Lindholm, Fredrik U. Jönsson

An important task for the law enforcement is to assess the accuracy of eyewitness testimonies. Recent research show that indicators of effortful memory retrieval, such as pausing and hedging (e.g. “I think”, “maybe”), are more common in incorrect recall. However, a limitation in these studies is that participants are interviewed shortly after witnessing an event, as opposed to after greater retention intervals. We set out to mitigate...
