What is Natural Selection?01:32

What is Natural Selection?

126.5K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Regulation of Expression Occurs at Multiple Steps

25.8K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Nature and Nurture01:10

Nature and Nurture

22.2K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

55.6K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Errors occurring during blood pressure monitoring

1.3K
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
Several factors...

Summary

Children using augmentative and alternative communication (AAC) systems preferred visual scene displays (VSDs) over grid displays during song activities. This study highlights VSDs as a potentially more effective communication tool for beginning communicators.

Area of Science:

  • Augmentative and Alternative Communication (AAC)
  • Developmental Disabilities
  • Inclusive Education

Background:

  • Limited research exists on communication displays for beginning AAC users during specific functional activities.
  • Visual scene displays (VSDs) are less explored compared to traditional grid displays for this population.
  • Song cloze opportunities represent a unique communicative function for AAC users.

Purpose of the Study:

  • To compare the effectiveness of visual scene displays (VSDs) versus standard grid displays for AAC users during song cloze phrases.
  • To evaluate user preference between VSDs and grid displays in an inclusive camp setting.
  • To investigate independent responding in children with intellectual and developmental disabilities using different AAC display types.

Main Methods:

  • An alternating treatment design was employed to compare VSDs and grid displays.
  • The study involved five children with intellectual and developmental disabilities during camp 'morning song' sessions.
  • Participants selected the next word in a song during cloze phrases, with responses analyzed for independence.

Main Results:

  • A significant preference for the visual scene display (VSD) over the traditional grid display was observed.
  • Statistical and visual analyses indicated greater independent responding with VSDs.
  • Preference assessments suggested participants favored responding via the VSD interface.

Conclusions:

  • Visual scene displays (VSDs) may be more effective than grid displays for beginning AAC communicators in song-based activities.
  • VSDs show promise for enhancing engagement and independent participation for children with developmental disabilities.
  • Further research is needed to explore VSDs in diverse communicative functions and populations.
