Understanding Emotions: Components, Theories, and Brain Areas
Emotions Components
- Feelings
- Cognitions
- Actions
James-Lange Theory
2 Hypotheses:
- Weaker action/physiology = less emotion
- Stronger action/physiology = stronger emotion
Is physiological arousal sufficient for emotions?
Möbius Syndrome (M.S.)
Condition where subjects are unable to move facial muscles for smiling.
- M.S. subjects are able to experience happiness & joy.
- Autonomic rather than muscular activity triggers affective components of emotions.
Brain Areas Associated with Emotion
- Limbic system: areas of
Understanding Criminal Behavior: Serial Killers and Domestic Abuse
Serial Killers and the Psychology of ‘Nothing to Lose’
When an author (perpetrator) feels they have nothing left to lose, the significance of a murder diminishes. Bank robbers, cornered during an escape after a prior killing, exemplify this. In the majority of killings and assassinations, police identify the perpetrator relatively easily; approximately 90% of these crimes are solved. The remaining 10% often involve mishandled judicial investigations, such as failing to properly seal the crime scene,

*Valid logic: True premises always lead to a true conclusion. Sound logic: The argument is valid and all of the premises are true
Hypotheses:
Directional alternative hypothesis: –
Group 1 will perform better than Group 2 -As X goes up, so does Y -As X goes up, Y goes down
Causal or Associative Hypotheses — –
Some attempt to define a causal relationship -The experimenter must be in control of the cause -“If I change X, then I think that Y will also change” …-Co-Occurrence: -The presumed cause
Capacitor and Circuit Problems: Solutions and Analysis
Problem 1: Spherical Capacitor
A spherical capacitor consists of a thin conducting shell of radius a, surrounded by a thin conducting shell of radius b (where b > a). When the capacitor is connected to a battery, the inner shell has charge +Q and the outer shell has charge –Q.
(a) Let r denote the distance from the center of the shells. Use Gauss’s law to find a symbolic expression for the electric field between the shells.
(b) Find a symbolic expression for the magnitude of the potential difference

Econometrics, literally “economic measurement,” is a branch of economics that attempts to quantify theoretical relationships. Regression analysis is only one of the techniques used in econometrics, but it is by far the most frequently used.
Major Uses of Econometrics
- Description
- Hypothesis testing
- Forecasting
The specific econometric techniques employed may vary depending on the use of the research.
Regression Analysis and Causality
While regression analysis specifies that a dependent variable is a
