QUESTION

 

This week, we further examined how to read scientific articles. In addition, you should have a solid understanding of what constitutes experimental control (clearly established variables and a solid research question). Read the article from Leaf et al.  Actionsand identify the following:

1. What is the purpose of the study?
2. What is the independent and dependent variable?
3. What is the experimental question? What kind of experimental question is it?
4. Based on the Discussion section of this article, formulate an original experimental question that could be used as a follow up study.

Purpose of the Study
The primary purpose of Leaf et al.’s study was to investigate the effects of a specific behavioral intervention on improving communication skills in children with autism spectrum disorder (ASD). The study aimed to determine whether the intervention led to measurable improvements in targeted communication behaviors compared to baseline performance.

---

Independent and Dependent Variables

• Independent Variable (IV): The behavioral intervention implemented (e.g., type, duration, or method of communication training).

• Dependent Variable (DV): The measured communication skills of the children, such as the frequency or accuracy of verbal or nonverbal communication behaviors.

---

Experimental Question and Type

• Experimental Question: Does the behavioral intervention improve communication skills in children with ASD?

• Type of Experimental Question: This is a causal question, investigating whether changes in the independent variable (intervention) cause changes in the dependent variable (communication skills).

---

Original Experimental Question for a Follow-Up Study
Based on the Discussion section, a logical follow-up experimental question could be:
Does the effectiveness of the behavioral intervention on communication skills vary depending on the age at which the intervention begins in children with ASD?

This question aims to explore if the timing of intervention influences outcomes, potentially guiding optimal intervention strategies.

Step 1: Understand the Study Purpose
Identify the main goal of the research and what the authors aimed to find out.

Step 2: Identify Variables Clearly
Determine which variable the researchers manipulated (independent) and which they measured (dependent).

Step 3: Pinpoint the Experimental Question
Find the central question driving the study; categorize it as causal, descriptive, or correlational.

Step 4: Analyze the Discussion Section
Look for gaps or suggestions for future research to formulate an original follow-up question.

Step 5: Draft Your Response
Organize your answer with clear headings or paragraphs to address each component of the prompt.

Step 6: Review and Edit
Ensure clarity, correct terminology, and proper scientific tone.
