Psychology Assignment 350 Words

Professor Smith wants to study hand-eye coordination across the lifespan. Discuss a strength and a limitation of using cross-sectional and longitudinal research designs for this study. Strengths and weaknesses should not be framed as simple opposites of one another.

English Assignment 350-450 Words

· Resource:

In this exercise, you will practice annotating a digital text. You will complete this assignment in your chosen Word processor using the built-in note-taking / comment function (see module resources).

To complete the exercise, download the attached article below in your preferred format (Google Doc or Microsoft Word). As you read the article, you should attempt to highlight and annotate the article according to the “Writing in the Margins” handout included in module readings, to include notes on

· Visualization

· Connection

· Response/ Reaction

· Summarization/ Paraphrasing

· Questioning

· Analysis

After you have read through the article and commented in the margins, you will produce a short summary of the article. Consult your annotations to help you remember what stood out to you about a text, and remember: summary is about factual recall. When writing a summary, you should strive to understand the overall focus of a text as well as the main ideas the text uses to support that focus. You should be able to summarize a text without looking at it. This is how to gauge whether or not you  understand a piece of writing. You can still look back at the text for  specific information, but you should be able to explain the article without looking at it.

Assignment Guidelines

· For the annotations: The successful assignment will include some marginal notes for each paragraph of the article as well as a short reflection at the end that summarizes the main ideas explored in the article.

· For the summary: The successful summary will fully represent the main focus and supporting ideas for the article provided.

Professor Smith wants to study hand-eye coordination across the lifespan. Discuss a strength and a limitation of using cross-sectional and longitudinal research designs for this study.

Cross-sectional and longitudinal research designs are useful for studying hand-eye coordination across the lifespan. The strengths of each design include:

• They allow for researchers to examine the same group of people during different points in time (cross-sectional) or over an extended period of time (longitudinal). These two types of studies allow you to compare results from one group with another, which can help you understand why certain aspects change over time.
• Cross-sectional studies also allow you to determine how much someone’s performance has changed between two different times or places–for example, whether they improved their accuracy at age 21 versus 36 years old–and then compare those results against each other. This allows us to see if there are differences between groups based on age instead of gender alone…

There are strengths and limitations when using different types of studies in research.

• Cross-sectional studies are useful for making comparisons between groups. They can be used to compare the abilities of people in different age groups or with different disabilities, for example.
• Longitudinal studies are useful for looking at changes over time, because it’s possible to follow a group of people over time and measure their performance on particular tasks as they progress through life stages.
• A longitudinal study would also be more accurate than a cross-sectional one because it allows researchers to monitor participants’ performance over many years instead of just one observation point (for example: when they decided whether or not they were going to conduct the study). This means that you will know exactly how much each individual improved during their training period–and whether those improvements were due solely to practice or other factors that aren’t necessarily related directly back into your research topic.”

Conclusion

In this situation, Professor Smith wants to study hand-eye coordination across the lifespan. He has decided to use cross-sectional and longitudinal research designs for his study. The strengths of using one design over another are that it is easier to understand and interpret, but it does not give as much information about how people change over time as longitudinal studies do.
