A History of Personality Psychology: Part 2

In Part 1 of A History of Personality Psychology, we chronicled the development of the biological and theoretical basis for the existence of human personality. From the musings of Hippocrates and Plato to the tragic yet enlightening tamping rod accident suffered by Phineas Gage, psychology has come a long way in establishing the validity of personality. Shifting away from establishing the existence of personality, Part 2 of the history of personality psychology will be focused on the structure of personality.

How the Weather Impacts Your Work Habits and Buying Behavior

We all know the weather outside can tremendously impact our daily outlook on life, but what role does it play in our buying behavior and work habits? We associate sunshine with happiness and stormy weather with bad moods and misfortune. Indeed, there is no dearth of research supporting the fact that the forecast can significantly influence individuals’ mood and temperament. For example, increased sunshine is associated with better moods and an increased willingness to help others, and there is a mood disorder -- Seasonal Affective Disorder (SAD) -- characterized by depressive symptoms brought on by the winter months. It’s pretty much common sense in today’s day and age that nice weather makes us happy, but can it actually affect our daily behavior? The answer, it turns out, is yes, and researchers are working to figure out exactly how and why.

A History of Personality Psychology: Part 1

Section I: General Chronology and Driving Forces of Personality

The history of personality psychology dates as far back as Ancient Greece. Indeed, philosophers since the 4th Century BCE have been trying to define exactly what it is that makes us us. In 370 BCE, Hippocrates proposed two pillars of temperament: hot/cold and moist/dry, resulting in four humors or combinations of these qualities. The hot and dry combination was referred to as yellow bile, cold and dry as black bile, hot and wet was blood and cold and wet was phlegm. Though much of the work that arose from this theory of the Four Humors was medicinal in nature, it was also hypothesized a patient's personality could be influenced by humoral imbalances.

3 Marketing Lessons from Evolutionary Psychology

Throughout high school we all paid our dues and learned the basics. These basic classes, (whether it be American History or Biology) provided a foundation for our future education that ultimately would help us chose a career path. During my time in high school, math and science came easy to me, and I spent my free time working in labs doing research to better understand how to apply what I was learning, and decided to major in Evolutionary Biology (with an emphasis on Psychology) in college. Though I am grateful for my education and various lab experiences, I eventually realized the world of academia and research is not necessarily for me. As I now transition from academia to the business world, I am realizing that much of what I’ve learned from biology and evolutionary psychology -- two fields that people might view as unrelated to business and marketing -- is anything but unrelated. Many of the topics in these academic fields can provide new perspectives in the workplace when trying to solve real world problems. Evolutionary psychologists may not be the first people you’d expect to provide insight into the world of marketing, but I’ve extrapolated three ideas from my coursework in this area that I’ve found extremely valuable in daily marketing routines.

Psychological Traits vs. Personality Type Theory

In order to successfully sell a product you have to know who to sell it to. Therefore, being able to accurately characterize consumers is a crucial goal of marketing and consumer behavior research. But interest in creating these characterizations exists outside just the marketing world: developing systematic ways of describing people and their personalities has been a goal of psychology from its early days. From the begining,  personality traits and personality types have been understood to serve different purposes in research. Over the years there have been many different theories regarding what personality is, how it arises and how we can categorize it. For example, Sigmund Freud was a proponent of psychodynamic theories, suggesting that personality is influenced by the unconscious and the progression through psychosexual stages, and B.F. Skinner advocated for behavioral theories that view personality as a result of individual interactions with the environment. One important (and ongoing) dichotomy in beliefs in this field is between type theory and trait theory. Like other theories in personality psychology, these two approaches attempt to systematically categorize people, but go about this goal in different ways.
