- A blending of senses, where one sensation is perceived as triggering another.
- Examples: "loud color," "sweet sound."
Theories of Synesthesia
- Enhanced Brain Connectivity: Individuals may have more connections between brain regions responsible for processing different senses.
- Feed-Backwards Connectivity: Connections carry information from multi-sensory areas to single sensory areas.
- Inhibited signals preventing information from flowing down the wrong path might be disrupted, causing cross-sensory experiences.
Priming
- Unconscious activation of associations stored in memory.
- Exposure to one thing can influence later behaviors or thoughts.

- A psychological test using headphones to present different auditory messages in each ear.
- Participants are instructed to focus on one ear while ignoring the other but can often pick up important words like their name from the ignored ear.
The Filter Model of Attention
- We filter out most incoming information, allowing only a small portion to reach conscious awareness.
- This allows us to focus on important information despite a bombardment of sensory input.
Physiological and Neurological Measures of Attention
- Neurocorrelates: Brain activity patterns, such as ERP (event-related potential) and PET (positron emission tomography), reveal changes in brain areas associated with attention.
- Orienting Response: Increased heart rate and galvanic skin response indicate a shift in focus.
- Pupil Dilation: Enlarged pupils show an increase in attention to a stimulus.
- Eye Movements: Tracking eye movements reveals what a person is attending to.
Change Blindness
- Failure to notice changes in the environment while trying to maintain object constancy.
Automaticity and Attention
- With practice, many tasks become automatic, freeing up cognitive resources for other activities.
Limitations of Automatic Processing
- While efficient and allowing multitasking, automatic processing lacks accuracy and may prevent us from fully appreciating life's richness.
Theories of Attention
- Bottleneck Theories: Limit the amount of information we can attend to at once.
- Automatic Versus Controlled Processing: Automatic processes are efficient for habitual tasks, while controlled processes are effortful for complex tasks.
- Feature Integration Theory: Focuses on the distribution of attention, with distributed attention recognizing single features automatically and focused attention required to integrate features for more complex objects.
ADHD and Attention
- Children with ADHD who fidget and wiggle during cognitive tasks may perform better.
- Movement provides stimulation and helps them regulate their attention.
Biofeedback for ADHD
- Training individuals to control autonomic processes like heart rate to manage ADHD symptoms.
Neurofeedback for ADHD
- A form of biofeedback that uses devices like EEGs and fMRI to measure brain activity and provide feedback to modify behavior.
- Neurofeedback aims to enhance brainwave patterns for improved attention.
Neurofeedback and ADHD Treatment
- Neurofeedback has shown to increase activity in the right inferior frontal cortex, a brain area crucial for cognitive control, thus improving ADHD symptoms.
Television and Attention
- Excessive TV viewing may contribute to attention problems due to its reliance on bottom-up processing, leading to external rather than internal control of attention.
Sleep Deprivation and Cognition
- Lack of sleep impairs the prefrontal cortex, negatively affecting attention, memory, decision-making, and memory consolidation.
- It disrupts the brain's ability to make broad connections between information.
Sleep Deprivation and Adolescents
- Teenagers who don't get enough sleep are at risk for health problems like high blood pressure, heart disease, diabetes, depression, and car accidents.
