Researchers record the average time it takes rats to complete the maze. In this study, the number of feed pellets was independent as per Manipulation of the Independent Variable
Manipulation of the Independent Variable Again, manipulating an independent variable involves systematically altering its levels so that different groups of participants are exposed to different levels of that variable, or This means that the groups will be exposed to different levels at different times. Independent variables are variables that researchers manipulate to better understand how phenomena, structure, and behavior are related to the dependent variable and Alternative Hypothesis . Instrumental variables are the independent variables in an experiment. It's called "manipulated" because it's something you can change. That is, you can decide in advance whether to increase or decrease. Experiments should always have only one instrumental variable.

Unconscious perception is inferred when a stimulus influences behaviors and/or neural activity
while the subject reports being unaware of it. Conscious perception<span> and attention are difficult to study, partly because their relation to each other is not fully understood. </span>
Answer:
These factores are: set point, life circumstances and intentional activity.
Which account for 50%, 10% and 40%, respectively, of the variability of happiness.
Explanation:
In the article called "Pursuing happiness: The architecture of sustainable change", Lyubomirsky et. al. (2005), propose a model for what they call chronic happiness. In this model they operationalize the concept of happiness in three measurable variables: set point, which are the genetic factors that influence a person's happiness, such as afective and personality traits. The authors found that this variable accounts for up to 50% of the entire construct.
The second variable is called life circumstances. These are the circumstantial factors that are relevant for a person's level of happines, they include demographic factors such as age, gender and ethnicity; and also life status, such as income and occupational status. The authors found that this variable accounts for only 10% of the construct.
The last variable is called intentional activity. It includes activities in which humans choose to engage in, in their everyday lives. For example, exercising, devoting time to helping others, etc. This variable accounts for 40% of the hapiness construct.
