AAQ: Practice Concepts (Review)

A group of researchers wanted to examine the impact of classroom temperature on students’ problem-solving abilities. They randomly assigned students to rooms set at either 65°F or 80°F and measured their performance on logic puzzles. What research method was used?

• Meta-Analysis

• Case Study

• Naturalistic Observation

• Correlational Research Study

• Experiment

A psychologist followed a single individual with an exceptionally high pain tolerance for over a decade, documenting how their experiences and brain activity differed from the general population. What research method was used?

• Naturalistic Observation

• Experiment

• Meta-Analysis

• Correlational Research Study

• Case Study

A team of scientists reviewed and analyzed 30 studies on the effects of mindfulness meditation on reducing workplace stress, combining the data to identify overall trends. What research method was used?

• Naturalistic Observation

• Correlational Research Study

• Experiment

• Case Study

• Meta-Analysis

Researchers observed individuals in a public park to examine how frequently people use their smartphones while walking. They recorded usage patterns without interacting with the subjects. What research method was used?

• Correlational Research Study

• Meta-Analysis

• Case Study

• Naturalistic Observation

• Experiment

A research team surveyed 1,000 office employees about their average daily caffeine intake and the number of hours they reported feeling alert at work. The researchers analyzed whether a statistical relationship existed between these variables. What research method was used?

• Naturalistic Observation

• Experiment

• Meta-Analysis

• Correlational Research Study

• Case Study

A study examined whether drinking cold or hot beverages affects reaction time. Participants drank either iced coffee or hot coffee and then completed a computerized reaction time task. What is the operational definition of the dependent variable?

• The temperature of the coffee consumed

• The type of coffee (hot or iced) provided

• The speed at which participants responded in the task

• The amount of coffee participants consumed

A study investigated whether taking handwritten or digital notes leads to better comprehension of lecture material. Participants used one of the two note-taking methods before completing a comprehension test. What is the operational definition of the independent variable?

• The type of note-taking method (handwritten vs. digital)

• The difficulty level of the lecture material

• The participants’ prior knowledge of the topic

• The total number of pages of notes taken

A study found that students who reviewed study materials for at least 45 minutes per session had an average test score of 85%, while those who reviewed for less than 20 minutes had an average score of 65%. What does the mean score of 85% indicate?

• All students in the 45-minute group scored exactly 85%.

• The average test score for students in the 45-minute group was 85%.

• The majority of students in the 45-minute group scored below 85%.

• Every student in the 45-minute group performed better than those in the 20-minute group.

In an experiment on exercise and memory retention, researchers found that test scores in the physically active group had a standard deviation of 4 points. What does this standard deviation suggest?

• Most participants’ scores were within 4 points of the average.

• The average score on the memory test was 4 points.

• The range of scores was exactly 4 points.

• Every participant scored exactly 4 points apart.

Before participating in a study on the impact of social media on stress levels, all participants were informed about the procedures, potential risks, and their right to withdraw at any time. They signed a document agreeing to these conditions. Which ethical guideline was followed?

• debriefing

• protection from harm

• informed consent

• confidentiality
