In the present study, the parenting practices and developmental expectations were examined in a sample of 96 fathers from Mexico and the United States, all with children from 1 to 5 years of age. The selection of fathers from both countries was controlled for the family's socioeconomic status (SES) and for the age and gender of their children. The Parent Behavior Checklist, a 100-item rating scale was used to measure parents' developmental expectations and their discipline and nurturing practices. According to the results, Mexican and U.S. fathers did not differ significantly in their developmental expectations or parenting practices. In both countries, fathers from lower SES families were less nurturing and used more frequent discipline than fathers from higher SES families.

Recent studies in vertebrates and Caenorhabditis elegans have reshaped models of how the axon guidance cue UNC-6/Netrin functions in dorsal-ventral axon guidance, which was traditionally thought to form a ventral-to-dorsal concentration gradient that was actively sensed by growing axons. In the vertebrate spinal cord, floorplate Netrin1 was shown to be largely dispensable for ventral commissural growth. Rather, short range interactions with Netrin1 on the ventricular zone radial glial stem cells was shown to guide ventral commissural axon growth.

Introduction: Children growing up in arid and semi-arid regions of Sub-Saharan Africa (SSA) face heightened risks, often resulting in poor developmental outcomes. In Kenya, the arid and semi-arid lands (ASAL) exhibit the lowest health and developmental indicators among children. Despite these risks, some children grow up successfully and overcome the challenges.

Planning has been studied in different fields of psychology, including cognitive, developmental, personality, social, and work and organizational research. This article looks at the planning process through the lens of motivation science, and asks the question, What kind of planning can help people reach their goals? We focus on the strategy of making if-then plans (also known as forming implementation intentions). We discuss what kinds of cognitive performance can be enhanced by if-then planning (e.

As lineages become separated in time, they are expected to accumulate mutational (or developmental-genetic) differences that influence the macroevolutionary trajectories of those lineages even under similar environmental conditions. Here, we compare the dynamics of phenotypic evolution in radiations of scincid lizards from Australia and Madagascar that are separated by more than 100 million years of independent evolution and show rampant phenotypic parallelism. We collected linear measurements of the skull, limbs, and limb girdles from micro-CT scans of 94 Australian and 29 Malagasy species.

Background: Children born with cleft palate ± lip (CP ± L) are at risk of speech sound disorder (SSD). Up to 40% continue to have SSD at age 5-6 years. These difficulties are typically described as articulatory in nature and often include cleft speech characteristics (CSC) hypothesized to result from structural differences.
