Design of Experiments: Key Concepts and Designs
Design of Experiments: Key Concepts
Design of Experiments (DOE) is the rational planning of experiments to obtain the maximum amount of information with the minimum number of trials. Its function is to analyze results and obtain evidence to test previously established hypotheses.
DOE is directly related to the problem statement and the hypothesis. The design aims to collect data from reality to solve the problem, and the hypothesis guides the type of experimentation needed to obtain, analyze, and

Unit VI: Theory
It is an assumption that establishes the existence of a relationship between two or more variables expressed as facts, events, or factors, and should be tested to be accepted as valid. Role of Hypotheses: Guide and direct an investigation. The assumptions should be deducted from the problem and aim to study and be consistent with the theoretical framework underpinning the work. Determine the type of study to follow and the design methodology that is planned for testing.

Proprioception & Touch: Sensory Mechanisms
Proprioception and Touch: Sensory Mechanisms
Proprioception
Proprioception refers to the sense of the position of joints, tension in muscle fibers, and the overall position of the body.
Touch
Touch involves the perception of spatial and temporal patterns of pressure on the skin.
- Deformation of the capsule surrounding sensory nerve fiber endings leads to stretching of the membrane.
- This stretching increases the probability of opening stretch-sensitive cation channels.
- A net influx of Na+ leads to depolarization

Social and Cross-Cultural Psychology: Concepts and History
Concept and Scope of Social Psychology
Social psychology is the systematic study of people’s thoughts, feelings, and behaviors in social contexts. It’s the scientific study of how we feel about, think about, and behave toward the people around us and how our feelings, thoughts, and behaviors are influenced by those people. The subject matter of social psychology is broad and relevant to everyday life. Social psychologists study why we are helpful or aggressive, the benefits of relationships, and

Frontal Lobe
The frontal lobe controls emotions and adaptation of personality to event experiences. It is also responsible for foresight, imagination, and self-awareness. Main areas of the frontal lobe include:
Parietal Lobe
The parietal lobe is the principal sensory area for touch. Lesions can cause sensory issues and impairment in cognitive receptive speech.
Temporal Lobe
The temporal lobe is involved in cognition, emotion, and memory.
Occipital Lobe
The occipital lobe is responsible for vision, visual
