Do the dual-task and PRP paradigms provide a reliable measure of multitasking costs?

Project description
Researcher has to provide the data analysis file together with the paper. Further detail will be attached shortly.

Cognitive Psychology – research topic:
Do the dual-task and PRP paradigms provide a reliable measure of multitasking costs?
For this question, one can measure the split-half reliability of each measure to see if they each provide a reliable measure of the cost. Split-half reliability can be measured by splitting the trials of each subject into halves (e.g., odd and even trials) and then compute the correlation of the costs calculated based on the two halves across subjects. Another analysis is to further split the trials into three parts, four parts, etc., to see how the reliability changes. That way we will have a better idea about how many trials are enough to provide a reliable cost measure for each task. It’s a more technical question with more analyses to do but less literature review and synthesis required.

Experiment conducted and data collected:
I have written a computer java based application to examine on the reaction time of the dual task and PRP paradigms. We have invited 23 participants to perform the task. Please find the description of the experiment in the Method – paradigms_20150227.docx file.

I have the data collected and placed in the zip files, DualTask and PRP There are several outliers especially in the Audio-Vocal task due to sensitivity of the microphone during the experiment. Please apply the
Schumacher et al. (1999) method first to identify cutoff RT and eliminate the outlier.

Please perform the data analysis in SPSS and provide the output file along with the paper. Please focus in the technical data analysis in this paper

The essay should follow the below hierarchy

–    It should precisely and concisely reflect the core content of the paper.

–    It should provide a brief and accurate summary of the entire work done, explaining why the investigation was conducted, what the aims were, how the aims were met, and what the main findings were.

Introduction, addressing the following
–    Motivation of your work: What specific questions about development and what specific individual(s) were examined? Why were you interested in examining these questions in these individual(s)? What is the potential contribution of your work to the literature of developmental psychology and to the life of the individual(s) examined?
–    Literature review for your work: What concepts, theories and previous findings guide your formation of your research questions and your expected answers to the questions?

Method, including the following

Participants – Which individual(s) were studied (e.g., one child/adolescent/adult or one parent, or a few/a small group of children/adolescents/adults or parents)?

Procedure – How information about the development of the individual(s) under study was collected (e.g., obtaining archives such as diaries, family photo albums, school reports or award certificates, conducting observations, administering tests, interviews or surveys)?

Measures – What observation protocols, test, interview, or survey questions were used?

Results, including the following

–    How the information collected was analyzed to answer the questions about development being investigated (e.g., content analyses or statistical analyses)?
–    What were the results from the analyses?

Discussion, addressing the following
– Reliability of the result? Individual difference?
– Justification on whether the number of trail is enough
–    Were the results consistent with your expectations? How the results may be understood given the concepts, theories and previous findings referred to in the Introduction section?
–    Theoretically, how may your work contribute to the literature of developmental psychology (e.g., how may your work confirm or disconfirm extant theories and prior studies? How may your work provide new knowledge beyond extant theories and prior studies?)
–    Practically, what insights into the development of the individual(s) being studied may be gained through your work? What recommendations may be suggested by your work for promoting optimal development of the individual(s) being studied?
–    What limitations may there be of your work? How future work may be improved and what directions future work may follow?

References (While the textbook and the lecture notes may be the major references and be cited, additional literature search by students themselves may be needed.)

Tables and figures (optional)
–    E.g., tables and figures summarizing and illustrating research questions being focused on, characteristics of individuals being studied and results from content or statistical analyses

–    Consent forms signed by the individual(s) being studied are required to be included as an
Appendix. Other appendixes are optional and may include full lists of observation
protocols, test, interview or survey questions used; record sheets from observations or tests, notes from interviews or transcripts of audio-recorded interviews; scanned copies of archival documents.

APA format: Sections/subsections, headings/subheadings, and referencing styles (e.g., in-text citations, references list, tables and figures) should be used appropriately and consistently throughout the paper.
