Abstract

This individual's Overall Mood is generally 22% higher than normal after an average of 630 index Brain Performance Index From Lumosity BPI over the previous 24 hours. This individual's data suggests with a high degree of confidence (p=3.2680785081814E-9, 95% CI 0.435 to 1.139) that Brain Performance Index From Lumosity BPI has a strongly positive predictive relationship (R=0.79) with Overall Mood. The highest quartile of Overall Mood measurements were observed following an average 1 index Brain Performance Index From Lumosity BPI. The lowest quartile of Overall Mood measurements were observed following an average 991.45454545455 index Brain Performance Index From Lumosity BPI.Overall Mood is generally 24% lower than normal after an average of 991.45454545455 index of Brain Performance Index From Lumosity BPI over the previous 24 hours. Overall Mood is generally 22% higher after an average of 1 index of Brain Performance Index From Lumosity BPI over the previous 24 hours.

Objective

The objective of this study is to determine the nature of the relationship (if any) between Brain Performance Index From Lumosity BPI and Overall Mood. Additionally, we attempt to determine the Brain Performance Index From Lumosity BPI values most likely to produce optimal Overall Mood values.

Design

This study is based on data donated by one participant. Thus, the study design is consistent with an n=1 observational natural experiment.

Data Analysis

Brain Performance Index From Lumosity BPI Pre-Processing
Brain Performance Index From Lumosity BPI measurement values below 0 index were assumed erroneous and removed. No maximum allowed measurement value was defined for Brain Performance Index From Lumosity BPI. No missing data filling value was defined for Brain Performance Index From Lumosity BPI so any gaps in data were just not analyzed instead of assuming zero values for those times.

Overall Mood Pre-Processing
Overall Mood measurement values below 1 out of 5 were assumed erroneous and removed. Overall Mood measurement values above 5 out of 5 were assumed erroneous and removed. No missing data filling value was defined for Overall Mood so any gaps in data were just not analyzed instead of assuming zero values for those times.

Predictive Analytics
It was assumed that 0 hours would pass before a change in Brain Performance Index From Lumosity BPI would produce an observable change in Overall Mood. It was assumed that Brain Performance Index From Lumosity BPI could produce an observable change in Overall Mood for as much as 1 days after the stimulus event.
Predictive Analysis Settings

Data Quantity
73 raw Brain Performance Index From Lumosity BPI measurements with 68 changes spanning 347 days from 2012-04-16 to 2013-03-29 were used in this analysis. 13635 raw Overall Mood measurements with 1192 changes spanning 2522 days from 2012-05-06 to 2019-04-01 were used in this analysis.

Data Sources

Brain Performance Index From Lumosity BPI data was primarily collected using QuantiModo. QuantiModo allows you to easily track mood, symptoms, or any outcome you want to optimize in a fraction of a second. You can also import your data from over 30 other apps and devices. QuantiModo then analyzes your data to identify which hidden factors are most likely to be influencing your mood or symptoms.

Limitations

As with any human experiment, it was impossible to control for all potentially confounding variables. Correlation does not necessarily imply causation. We can never know for sure if one factor is definitely the cause of an outcome. However, lack of correlation definitely implies the lack of a causal relationship. Hence, we can with great confidence rule out non-existent relationships. For instance, if we discover no relationship between mood and an antidepressant this information is just as or even more valuable than the discovery that there is a relationship.
We can also take advantage of several characteristics of time series data from many subjects to infer the likelihood of a causal relationship if we do find a correlational relationship. The criteria for causation are a group of minimal conditions necessary to provide adequate evidence of a causal relationship between an incidence and a possible consequence.

The list of the criteria is as follows:
Strength (A.K.A. Effect Size)
A small association does not mean that there is not a causal effect, though the larger the association, the more likely that it is causal. There is a strongly positive relationship between Brain Performance Index From Lumosity BPI and Overall Mood

Consistency (A.K.A. Reproducibility)
Consistent findings observed by different persons in different places with different samples strengthens the likelihood of an effect. Furthermore, in accordance with the law of large numbers (LLN), the predictive power and accuracy of these results will continually grow over time. 23 paired data points were used in this analysis. Assuming that the relationship is merely coincidental, as the participant independently modifies their Brain Performance Index From Lumosity BPI values, the observed strength of the relationship will decline until it is below the threshold of significance. To it another way, in the case that we do find a spurious correlation, suggesting that banana intake improves mood for instance, one will likely increase their banana intake. Due to the fact that this correlation is spurious, it is unlikely that you will see a continued and persistent corresponding increase in mood. So over time, the spurious correlation will naturally dissipate.

Specificity
Causation is likely if a very specific population at a specific site and disease with no other likely explanation. The more specific an association between a factor and an effect is, the bigger the probability of a causal relationship.

Temporality
The effect has to occur after the cause (and if there is an expected delay between the cause and expected effect, then the effect must occur after that delay). The confidence in a causal relationship is bolstered by the fact that time-precedence was taken into account in all calculations.

Biological Gradient
Greater exposure should generally lead to greater incidence of the effect. However, in some cases, the mere presence of the factor can trigger the effect. In other cases, an inverse proportion is observed: greater exposure leads to lower incidence.

Plausibility
A plausible bio-chemical mechanism between cause and effect is critical. This is where human brains excel. Based on our responses so far, 3 humans feel that there is a plausible mechanism of action and 14 feel that any relationship observed between Brain Performance Index From Lumosity BPI and Overall Mood is coincidental.

Coherence
Coherence between epidemiological and laboratory findings increases the likelihood of an effect. It will be very enlightening to aggregate this data with the data from other participants with similar genetic, diseasomic, environmentomic, and demographic profiles.

Experiment
All of human life can be considered a natural experiment. Occasionally, it is possible to appeal to experimental evidence.

Analogy
The effect of similar factors may be considered.
