This document summarizes research on using physiological signals to detect stress and deception. It discusses how voice pitch variation and heart rate variability can be used as features in artificial neural networks to identify high stress situations and lying with up to 82% and 71% accuracy, respectively. The document also reviews other research on using microexpressions, speech analysis, and polygraphs for lie detection and their limitations. Future work proposed includes improving accuracy by collecting additional physiological data like EEG and using higher resolution cameras.

Helpful Questions to Ask
1. What time do you generally go to bed and what time do you wake up?
Asking this is important as it helps to rule out night-time insomnia as the cause of the patient’s day time sleepiness. In order to diagnose her with a sleep/wake disorder, it has to be clear that her condition is being caused by an underlying issue that has nothing to do with the sleep itself.
1. What happens when you fall asleep?
Asking this allows the patient to explain in detail all the symptoms that she has been experiencing, with regard to her disorder. This information is crucial in helping to correctly diagnose a particular sleep/wake disorder.
1. Are you taking any medications? If so, which ones?
A number of health issues, including some sleep/wake disorders are have a lot to do with pharmacodynamics. The patients day time sleepiness may be caused by certain drug actions or interactions and as such would require a restructuring of their medication or dosages.
The person that would be most helpful in evaluating the patient’s sleep patterns in this case would be the husband. Given that she has no children and keep little contact with her family or friends, the husband is the only person who has stayed with the patient long enough to properly observe the quantity and quality of her sleep. In sleep evaluation cases, getting a second person’s assessment is important as the patient may not be able to correctly or exhaustively explain what happens when they fall asleep. In this case, specific questions to the patient’s husband would include the following:
1. What happens when your wife falls asleep? (This allows the husband to explain in his own words what he has observed in his wife’s sleep pattern.
2. What do you think causes her sleep to be this way? (This may help bring new information which the patient may have deliberately or unintentionally left out.)
In order to diagnose narcolepsy, a number of physical and diagnostic tests can be done. Physical tests generally involve learning the patient’s medical history, analyzing the patient’s symptom self-assessment, checking the patient’s vitals and observing their general appearance. A physical test reveals symptoms and patterns which may help the health practitioner diagnose the patient with a particular sleep/wake disorder. For instance, a narcoleptic patient’s physical exams would entail such symptoms as excessive daytime sleepiness, hallucinations, sleep paralysis and cataplexy. The physical test can also include an Epworth Sleepiness Scale (ESS) questionnaire, which is employed in many sleep clinics to evaluate patients’ sleep quantity and quality. In an ESS, patients are asked to rate a range of activities in which they are likely t ...

REVIEW: Previous Deception detection methods and New proposed method using in...IJERA Editor
Deception detection has important legal and medical applications, but the reliability of methods for the differentiation between truthful and deceptive responses is still limited. Deception detection can be more accurately achieved by measuring the brain correlates of lying in an individual. For the evaluation of the method, several participants were gone through the designed concealed information test paradigm and their respective brain signals were recorded. The electroencephalogram (EEG) signals were recorded and separated into many single trials. To enhance signal noise ratio (SNR) of P3 components, the independent component analysis (ICA) method was adopted to separate non-P3 (i.e. artifacts) and P3 components from every single trial. Then the P3 waveforms with high SNR were reconstructed. And then group of features based on time, frequency, and amplitude were extracted from the reconstructed P3 waveforms. Finally, two different class of feature samples were used to train a support vector machine (SVM) classifier because it has higher performance compared with several other classifiers. The method presented in this paper improves the efficiency of CIT and deception detection in comparison with previous reported methods.

A PRIMER ON CAUSALITY
Marc F. Bellemare∗
Introduction
This is the second of two handouts written to help students understand quantitative methods in the social
sciences. This handout is dedicated to discussing (some) of the ways in which one can identify causal
relationships in the social sciences. In keeping with the notation introduced in the handout on linear
regression, let 𝐷𝐷 be our variable of interest; 𝑦𝑦 be an outcome of interest; and the vector 𝑥𝑥 = (𝑥𝑥1, … , 𝑥𝑥𝐾𝐾)
represent other factors – or control variables – for which we have data. For the purposes of this discussion,
let 𝐷𝐷 measure a given policy, 𝑦𝑦 measure welfare, and the vector 𝑥𝑥 measure the various control variables the
researcher has seen fit to include. See my “A Primer on Linear Regression” for a more basic handout.
Mechanics
Recall that the regression of 𝑦𝑦 on (𝐷𝐷, 𝑥𝑥1, … , 𝑥𝑥𝐾𝐾) is written as
𝑦𝑦𝑖𝑖 = 𝛼𝛼 + 𝛽𝛽1𝑥𝑥1𝑖𝑖 + ⋯ + 𝛽𝛽𝐾𝐾𝑥𝑥𝐾𝐾𝑖𝑖 + 𝛾𝛾𝐷𝐷𝑖𝑖 + 𝜖𝜖𝑖𝑖, (1)
where i denotes a unit of observation. In the example of wages and education, the unit of observation would
be an individual, but units of observations can be individuals, households, plots, firms, villages, communities,
countries, etc. Just as the research question should drive the choice of what to measure for 𝑦𝑦, 𝐷𝐷, and 𝑥𝑥, the
research question also drives the choice of the relevant unit of observation.
The problem is that unless the researcher runs an experiment in which she randomly assigns the level of 𝐷𝐷 to
each unit of observation i, the relationship from 𝐷𝐷 to 𝑦𝑦 will not be causal. That is, 𝛾𝛾 will not truly capture the
impact of 𝐷𝐷 on 𝑦𝑦, as it will be “contaminated” by the presence of unobservable factors. Some of those factors
can be included in 𝑥𝑥 = (𝑥𝑥1, … , 𝑥𝑥𝐾𝐾), of course, but it is in general impossible to fully control for every relevant
factor. This is especially true when unobservable or costly to observe factors (e.g., risk aversion, technical
ability, soil quality, etc.) play an important role in determining 𝐷𝐷 and 𝑦𝑦. So even if we get an estimate of 𝛾𝛾
that is statistically significant, we cannot necessarily assume that the relationship between the variable of
interest and the outcome variable is causal. In other words, correlation does not imply causation.
For example, suppose 𝐷𝐷 is an individual’s consumption of orange juice and 𝑦𝑦 is (some) indicator of health.
We have often discussed in lecture how a simple regression of 𝑦𝑦 to 𝐷𝐷 would provide us with a biased
estimate of 𝛾𝛾 because orange juice consumption is nonrandom and not exogenous to health. That is, there
are factors other than orange juice consumption which determine health. Some are observable (e.g., how
much someone exercises; whether they smoke; their diet; etc.), but several are unobservable (e.g., their
willingness to pay for orange juice; their subjective valuation of health; th
A Review of ECG signals for Human Emotion Detectionrahulmonikasharma
This article evaluates the present development by means of literature review in determining the association between emotions, mainly worry, and the various physiological signals with special attention on the exclusive patterns of the electrocardiogram or ECG waveform. An initial investigation was carried out to evaluate which aspects in the ECG waveform can be most suitably related with worry, except from those. Hence, it has been observed that emotion identification utilizing particular aspects of ECG is investigated to a lesser degree compared to other physiological reactions like speech signals, skin conductance and temperature, facial expression, heart rate and blood pressure. With the initial investigation, it was further discovered that the T waves levels out consequently and there is some likelihood of P waves.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
