Questions and Answers
Optical illusions like Kanizsa Triangle and Penrose Stairs demonstrate how our brain fails to fill in missing information to create meaningful shapes and structures.
False
Perception is influenced solely by sensory input from the environment, without any influence from experiences, expectations, or emotions.
False
Top-down processing in perception involves creating individual representations influenced by neural, cognitive, and social processes, while bottom-up processing involves sensory sensations.
True
The priming effect can influence perception, as shown in examples where primed individuals are less likely to see specific objects in ambiguous images.

Study Notes
- Optical illusions like Kanizsa Triangle and Penrose Stairs demonstrate how our brain fills in missing information to create meaningful shapes and structures.
- Human perception involves all sensory organs gathering information from the environment, converting it into signals, and interpreting it in the brain.
- Perception is influenced by experiences, expectations, and emotions, leading to errors or distortions in how we perceive the world.
- Two main principles in psychology for sensory perception are Bottom-up processing (sensory sensations) and Top-down processing (creating individual representations influenced by neural, cognitive, and social processes).
- Priming effect can influence perception, as shown in examples where primed individuals are more likely to see specific objects in ambiguous images.
- Optical illusions challenge our perception, such as seeing moving patterns in static images or misjudging the lengths of lines due to surrounding context.
- Human perception is subjective, shaped by individual knowledge, experiences, and motivations, leading to self-serving biases that make it difficult to recognize errors or inappropriate behavior.- Only 40 out of 11 million bits of information are consciously processed by the brain.
- Most processing occurs subconsciously, with attention playing a crucial role in directing conscious awareness.
- Attention is like a flashlight, directing focus on specific things for conscious perception.
- Concentration involves focusing attention intensively on a task, leading to states like "Flow" where productivity peaks.
- Selective attention involves filtering out irrelevant information to focus on specific stimuli consciously.
- The brain filters sensory information in stages, from sensory register to conscious perception.
- Examples like finding a red square demonstrate how selective attention works, with challenges increasing with more complex stimuli.
- The Cocktail Party Effect illustrates how the brain subconsciously processes background information while focusing on specific stimuli consciously.
