Cognitive Biases, Developmental Stages & Clinical Psychology
Cognitive Heuristics and Biases
- Availability Heuristic — Judging based on how easy it is to think of examples or occurrences.
- Representativeness Heuristic — Judging based on how it resembles another event.
- Numerosity Heuristic — Judging quantity/probability based on the number of pieces something has been divided into.
- Anchor-and-Adjust Bias — Making a guess by anchoring and pivoting around a previous estimate; there is a bias toward under-correction.
- Above-Average Effect — The finding that
Organizational Change Models and Resistance: Schein, Lewin, Kotter
1. Technological Approach to Change
The technological paradigm views organizational change as a structured, mechanical process:
- Change can be 100% planned and controlled by management.
- Change is treated as a technological process.
- Change requires hard competencies: the success of the change depends on the technical skills of the implementers rather than on emotional intelligence.
- Mistakes result from bad planning or incorrect implementation.
- We can avoid mistakes.
2. Social and Interpersonal Approach to

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
