Hypothesis:

H1: Participants who complete the Response Time Task B will have shorter response

times compared to participants who complete the Response Time Task A.

H0: There will be no difference in response times between participants who complete

Response Time Task A and those who complete Response Time Task B.

Variables

Independent variable

The independent variable in this experiment is Task A or Task B Response Time Task.

Type of IV: Categorical, with two levels (Task A, Task B)

Dependent variable

The dependent variable is the response time, this is a continuous ratio-scaled dependent

variable (DV). After three seconds for mistakes, response time is the entire time it takes to

answer.

Covariate

The presence of music. This represents another factor that potentially affects the IV-DV

relationship, it must be included during the investigation. It is a nominal variable.

Design

The design is Experimental design. The experiment uses a Between-Subjects design,

where participants are randomly assigned to complete either Response Time Task A or Response

Time Task B. This design allows for a direct comparison of response times between the two

groups and helps control for potential confounding variables (Paradis-Gagné & Pariseau-Legault,

2022).

Kelly Schmitt
Why? Specify the IV (what was different about Phase I vs Phase II)?
Kelly Schmitt
IV - your main IV is not Task A or Task B. Rather it is the difference between Part I (week 5) and Part II (week 6). Go back to these weeks if that is unclear to you. We also went over this main IV in your live session when summing data.
Kelly Schmitt
Kelly Schmitt
No, music presence or absence is your main IV. The covariate is something else measured (hint: demographic variable)
Kelly Schmitt
You should have 3 types of design here. Be sure to define each (you are correct on experimental design) and explain why this study fits. It is not between subjects.

Participants

The experiment does not provide specific details about the participants, such as their

location, recruitment, or other descriptions. More information about the participants would be

needed to fully describe this section.

Materials

Research materials for this study were Task A and Task B response time assignments.

Strong test-retest reliability for both tasks proves they are valid reaction time measures (Doyle et

al., 2020). Although the guidelines did not mention validity, the fact that the two tasks are

"equivalent measures of response time" suggests that they are quite valid for evaluating response

time.

Procedure

The procedure for this experiment involves randomly assigning participants to complete

either Response Time Task A or Response Time Task B. Task A requires users to press keys that

match the forms (rectangles or circles) and colors (yellow or blue). In Task B, users must push

one key if they see "H" or "O" and another if not. Timed trials for both tasks follow the initial

practice. For every mistake, we subtract three seconds from reaction times to score task

performance. The study question and experiment aim to directly compare the two groups'

reaction times (Siedlecki, 2020).

Kelly Schmitt
Update once you have the data file - # of participants, how recruited, gender, etc
Kelly Schmitt
Be sure to describe tools needed -- e.g., computer, psytoolkit
Kelly Schmitt
Need to report reliability and validity as best you can.
Kelly Schmitt
People were not randomly assigned to different groups - everyone did the same thing
Kelly Schmitt
Much more info needed. Start from beginning - did they have informed consent? Describe part I in detail, then describe time between (Using real data), and then describe part II in detail.
