INSTRUCTIONS FOR COMPLETING THE ASSESSMENT:

We have collected data from the module group using the Cognimapp software. Hopefully you engaged in the data collection because that will help you understand what the different tests were. If you have not yet completed the tests then you can still do so via this link https://cognimapp.com/studies/2hsaFhspSi- 4SfUyoLn6sQ/signup/anon/ . However, it may be too late for your data to be included in the data set for analysis. The aim of this assignment is to use a range of statistical tests in order to investigate some potential lifestyle and biological influences on cognitive performance. The data are in the SPSS file ASSIGNMENT_COGNIMAPP.sav. The variables that were obtained from the tasks and questionnaire you completed are summarised in the table below.

VARIABLE NAMEVARIABLE DESCRIPTION
SRTSimple reaction time in milliseconds
CRT_ACCChoice reaction time accuracy (%)
CRTChoice reaction time in milliseconds
STROOP_ACC_CONGStroop task accuracy on congruent word colour trials (%)
STROOP_ACC_INCONGStroop task accuracy on incongruent word colour trials (%)
STROOP _RT_CONGStroop task reaction time on congruent word colour trials in milliseconds
STROOP_RT_INCONGStroop task reaction time on incongruent word colour trials in milliseconds
AGEAge of participant in years
SLEEP_HRSHours of sleep participant had last night
ALCOHOLDid the participant drink alcohol last night?
EXERCISEDoes the participant take part in regular exercise?
MOODRating of mood at time of test from 0 (sad) to 100 (happy)
CAFFEINEDid the participant consume caffeine on the day of testing?
WORD_ACCWord recognition accuracy (%)
WORD_RT_CORRECTWord recognition reaction time for correct responses in milliseconds
PIC_ACCPicture recognition accuracy (%)
PIC_RT_CORRECTPicture recognition reaction time for correct responses in milliseconds

There are a number of questions for you to answer that are detailed in the brief below. You will be required to use SPSS to analyse some of the variables in order to answer these. This assignment is not to be presented like a lab or research report. The aim is for you to demonstrate you can identify the correct test(s) to use for each question, correctly use SPSS or JASP to conduct the test(s), and to report appropriate summary tables and textual presentation of the findings with reference to statistical significance and effect sizes where appropriate. You should avoid over-analysing the data ie running and reporting additional tests that are not required to answer the questions as this can in fact make your answers less clear. It is important to note that you must not change the data set in any way eg as a consequence of non-normality or the presence of outliers.

The Brief

  • Calculate and present descriptive statistics for the four variables that relate to word and picture recognition. Present and comment on tests of normality for these variables, histograms with normal curves, and boxplots that may indicate the presence of outliers. Present and comment on a matrix of scatterplots between variables. Conduct Pearson correlations between variables and report in line with accepted conventions. (15 marks)
  • Conduct appropriate tests to compare the impact of caffeine consumption on the variables SRT, CRT_ACC, CRT, Sleep and Mood. Present the findings in line with accepted conventions and comment on the results. (20 marks)
  • Perform an analysis to examine the extent to which the variability in Picture recognition reaction time (PIC_RT_CORRECT) might be explained by changes in Alcohol use, Sleep, Age and Mood. In addition to reporting the overall result, calculate and comment on the individual contributions the four predictors make. Conduct and comment on tests of collinearity and heteroscedasticity. (30 marks)
  • The Stroop task is made up of stimuli that are congruent (word and colour match) and incongruent (word and colour do not match). Analyse the data for congruent and incongruent stimuli to evaluate the extent that congruence affects accuracy and reaction time. (15 marks)
  • Analyse the data to identify if alcohol use and exercise affect word recognition accuracy. Do the two factors interact? (20 marks)

Appropriate referencing may be required in this assignment. All references must be in accordance with APA guidelines.

For clarity: work that is submitted up to 24 hours late that would have scored 65%, 55% or 45% had it been handed in on time will be awarded 55%, 45% or 35% respectively as 10% of the total available marks will have been deducted.
  • Coursework submitted more than 1 day (24 hours) after the published hand-in deadline without approval will be regarded as not having been completed. A mark of zero will be awarded for the assessment.

These provisions apply to all assessments, including those assessed on a Pass/Fail basis. The full policy can be found here.

However, the word limit DOES NOT INCLUDE a title page, contents page, tables, figures and their titles, reference list or appendices.
