Psychology of Personality Traits and Human Motivation
Personality Traits and Environment
Personality traits are relatively stable patterns of thoughts, feelings, and actions that distinguish one person from another across time and situations.
- Trait-Environment Interaction: Traits affect how people react to environments (e.g., extraverts respond positively to rewards).
- Trait-Environment Correlation: Traits influence the types of environments people choose (e.g., sensation seekers prefer adventurous activities).

Primary Visual Cortex
Q1: Why is the primary visual cortex called the striate cortex?
Question: 1) Why is the primary visual cortex often called the “striate” cortex?
Answer: It is called the striate cortex because, under the microscope, layer IV contains a visible stripe (the line of Gennari) formed by dense bands of myelinated axons arriving from the lateral geniculate nucleus (LGN). This distinct striation gives V1 its name and marks the major input layer that separates it from other cortical

Defining Stress and Its Types
Stress Defined: Stress is a process whereby an individual perceives and responds to events appraised as overwhelming or threatening to their well-being. It involves both physiological and psychological responses.
Subjective Appraisal: The perception of stress is highly individual. An event considered stressful by one person may not be perceived the same way by another. This appraisal significantly influences the intensity and nature of the stress response.

Principles of Effective Data Visualization
Foundations of Visualization
Goals
Leverage visuals to understand and communicate data. Goals can be broken down into four main categories:
- Record Information
- Analyze Data to Support Reasoning (Example: the analysis of O-ring data for the Challenger disaster.)
- Confirm Hypothesis (Example: exact contaminated water pump location from Dr. John Snow’s 1854 cholera map of London.)
- Communicate Ideas to Others
Why Visualization Works
It offloads cognitive work to the perceptual system; cognition and memory are

Here’s your revised text with relevant theories and key concepts bolded for emphasis:
Attachment Theories
Bowlby’s Monotropic Theory suggests that attachment is innate and pre-programmed for human survival. Humans are born with the need to attach to their offspring. This need to form one main attachment is known as monotropy.
Ainsworth’s Strange Situation is a laboratory observation designed to measure the quality of attachment and differences in attachment styles in infants. Devised in 1970,

Dr. Kaufman’s Sailboat Model of Needs
The Hull (the base of the boat): Represents our security and stability needs—things like safety, connection, and self-esteem. If the hull has “holes” (like trauma, fear, or instability), we cannot really move forward because all our energy goes into surviving or patching it up. These are the foundations that keep the boat steady.
The Sail: Stands for our growth and exploration needs—curiosity, purpose, love, and creativity. When we feel safe and stable,
