Assignment task:
For each prompt, answer the questions below. Short answers are fine, please do not write one-liners (exception for questions related to IVs). Make sure to elaborate on the hypotheses.
Prompt 1 In this research, the authors asked: How do people understand and represent the spatial relationships between objects in the environment? Do people have "spatial maps" in their head? In the study, typists copied paragraphs in four conditions that manipulated tactile (touching) feedback from the keyboard. They typed on a normal keyboard, a keyboard with the keys removed exposing the rubber buttons underneath, a flat circuit board without, and on a flat table with a laser projection keyboard. They measured the number of mistakes made. What is/are the independent variable/s? How many levels are there? What's a reasonable hypothesis/es (in your opinion)? What's the logic behind the hypothesis/es (in your opinion)? Need Assignment Help?
Prompt 2 In this research, a group of researchers were interested in whether working memory depends on the type of stimuli that people have to temporarily store, and the time available to memorize them. Some participants had to store words and other participants had to store colors. Participants had either 2 or 8 seconds to memorize the stimuli. Next, they were tested on a memory recollection task. What is/are the independent variable/s? How many levels are there? What's a reasonable hypothesis/es (in your opinion)? What's the logic behind the hypothesis/es (in your opinion)?
Prompt 3 In one study, college-aged participants performed a computer-tracking task involving skills analogous to those involved in driving. They either performed this task by itself (''single-task mode'') or performed it while doing a second task (''dual-task mode''). One of the second tasks was ''a shadowing task in which the participants performed the simulated-driving task while they repeated words that the experimenter read to them over a handheld cell phone''. The other dual task created even more of a cognitive burden-after hearing each word, instead of repeating it back, participants had to generate a new word starting with the final letter of the word said to them. What is/are the independent variable/s? How many levels are there? What's a reasonable hypothesis/es (in your opinion)? What's the logic behind the hypothesis/es (in your opinion)?
Prompt 4 To determine if maze learning is affected by the type of maze used, 20 rats are randomly assigned to learn a standard alley maze (i.e., includes side walls; located on the lab floor); another 20 learn an elevated maze (no side walls; raised above floor level). Learning is assumed to occur when the rats run through the maze without making any wrong turns. What is/are the independent variable/s? How many levels are there? What's a reasonable hypothesis/es (in your opinion)? What's the logic behind the hypothesis/es (in your opinion)? Prompt 5 In a study of first impressions, students examine three consecutive photos of a young person whose arms are covered with varying amounts of tattoos. In one photo, the person has no tattoos; in the second photo she/he has one tattoo on each arm; in the third photo, she/he has three tattoos per arm. From a checklist, students indicate which of five different majors the student is likely to be enrolled in and rate the young person on 10 different 7-point bipolar scales (e.g., one scale has emotionally insecure at one end and emotionally secure at the other end). What is/are the independent variable/s? How many levels are there? What's a reasonable hypothesis/es (in your opinion)? What's the logic behind the hypothesis/es (in your opinion)?
