Modulations in light intensity across a visual image could be caused by a flat object with varying pigmentation, such as wallpaper, or differential light reflection from a three-dimensional shape made of uniform material, such as curtains. A new study identifies key image cues that help the brain work out which interpretation to select.

Introduction It is well-established that high vowels tend to have a higher F0 than low vowels, a phenomenon known as Intrinsic Vowel F0 (IF0). However, the underlying cause of IF0 remains debated. Previous research suggests that IF0 is entirely of physiological origin, while other research indicates that it is acquired to enhance perceptual contrasts between vowels.

Parental vaccine hesitancy is a major obstacle to childhood vaccination. We examined parental socioeconomic status (SES) disparities in vaccine hesitancy, and the potential mediating roles of perceived social support and health literacy. A questionnaire survey was given to parents with children aged below 6 years from six provinces in China.

Social and sensory experiences across the lifespan can shape social interactions, however, experiencedependent plasticity is widely studied within discrete life stages. In the socially monogamous zebra finch, in which females use learned vocal signals to identify individuals and form long-lasting pair bonds, developmental exposure to song is key for females to show species-typical song perception and preferences. While adult mating experience can still lead to pair-bonding and song preference learning even in birds with limited previous song exposure ("song-naïve"), whether similarities in adult behavioral plasticity between normally-reared and song-naïve females reflect convergent patterns of neural activity is unknown.

In response to the COVID-19 pandemic, Israel prioritized pregnant women for vaccination, recognizing them as a high-risk group. This study aims to explore factors influencing the acceptance of Influenza, Pertussis (T-dap), and COVID-19 vaccines among pregnant women, focusing on attitudes, social norms, perceived control, and risk perceptions. Additionally, the study compares acceptance patterns between traditional vaccines and the newer COVID-19 vaccine.

This study used ANCOVA models to investigate how pandemic characteristics-spreading speed, severity, and vaccination requirements-affect travel intentions. The results reveal that these factors explain 31.7% of the variance in travel decisions, with disease-spreading speed and severity being the most significant determinants.
