The goal of this assignment is to develop an understanding of how to formulate research questions, hypotheses, and testing procedures in psychology, along with the practical application of data entry and variable analysis in SPSS. This encompasses creating hypothetical datasets for research scenarios, understanding variables, and explaining their roles within an experimental framework.

Research Question and Hypothesis

My chosen research question pertains to the psychological impact of sleep deprivation on cognitive performance. Specifically, I am interested in whether sleep deprivation affects short-term memory recall. The formulated hypothesis posits that individuals who experience sleep deprivation will perform worse on memory recall tasks compared to individuals with adequate sleep. This hypothesis aligns with existing literature suggesting that sleep deprivation impairs cognitive functioning (Drummond et al., 2006).

Testing the Hypothesis

The experimental procedure would involve recruiting a sample of adult participants and randomly assigning them to two groups: a sleep deprivation group and a control group with normal sleep. The independent variable (IV) is sleep condition, operationalized as either sleep deprivation (e.g., less than 4 hours of sleep) or normal sleep (7-8 hours). The dependent variable (DV) is performance on a standardized short-term memory recall test, measured as the number of items correctly recalled. Data collection involves administering the test after the sleep manipulation and recording scores for each participant.

Participants' data would be analyzed statistically to evaluate whether sleep deprivation significantly impacts memory performance, with the expectation that the sleep-deprived group will perform worse. An independent samples t-test could be used to compare the two groups’ mean scores, providing insight into the effect of sleep deprivation on memory.

Data Entry in SPSS

For the data entry, I would create variables in SPSS as follows:

  • Variable 1: SleepCondition
  • Variable 2: MemoryRecallScore

In the "Variable View," I would set "SleepCondition" as a Nominal variable, labeling it as "Sleep condition: Deprived vs. Normal." "MemoryRecallScore" would be set as a Scale (Interval) variable, labeled as "Number of items correctly recalled."

In the "Data View," I would input data for 15 participants, assigning "Deprived" or "Normal" to "SleepCondition" and their corresponding scores to "MemoryRecallScore." For example:

  • Participant 1: SleepCondition = Deprived; MemoryRecallScore = 5
  • Participant 2: SleepCondition = Normal; MemoryRecallScore = 9

Variable Explanation

The independent variable (IV) in this study is the sleep condition, which is categorized as either sleep deprivation or normal sleep. It is measured categorically, with values assigned as "Deprived" and "Normal." The dependent variable (DV) is the performance on the memory recall test, measured as the number of items correctly recalled (a continuous scale). The values are interpreted as the participant's performance level, with higher scores indicating better memory recall.

Measurement of the variables involves categorical coding for sleep condition and numerical score recording for memory performance. In analysis, the sleep condition variable helps group participants, while the scores are used to compare group means statistically.
