Study Notes

Brain Structure and Function

Maximizing surface area to volume ratio enhances brain function.
Optimal blood flow is maintained through the vascular structure of the brain.
Gyri (ridges) and sulci (valleys) increase cortical surface area.

Lobes of the Brain

Frontal Lobe
- Responsible for motor functions, planning, working memory, and speech production.
- Notably larger than in any other mammal.
Parietal Lobe
- Involved in touch sensation, body positioning, motor control, and spatial processing.
Occipital Lobe
- Specialized for visual processing.
Temporal Lobe
- Handles vision, object recognition, auditory processing, as well as smell, taste, and memory.

Subcortical Structures

Defined as structures located beneath the cortex.
Thalamus
- Acts as a sensory relay station, integrating and sending information to the cortex.
Hippocampus
- Key in memory formation, navigation, and spatial processing.
Amygdala
- Central to emotion processing.

Methods of Studying the Mind

Introspection and single cell recordings of neurons are two methods utilized to study mental processes.
Other methods include lesion studies, brain imaging, Event-Related Potentials (ERPs), and controlled experiments.

Lesion Studies

Examines patients with brain damage to specific regions, affecting behavior.
Observations are made before and after lesions to identify functional responses.
Double dissociation is used to compare different patients and behaviors linked to brain regions.

Double Dissociation Example

Damage to the hippocampus affects building recognition without impacting face recognition.
Damage to the fusiform area hinders face recognition but not building recognition.

Broca’s and Wernicke’s Areas

Broca’s Area
- Damage leads to Broca’s Aphasia, impacting language production but preserving comprehension, resulting in simplified speech.
Wernicke’s Aphasia
- Involves fluent but nonsensical speech with significant comprehension difficulties.

Brain Imaging Techniques

Electroencephalography (EEG)
- Measures electrical changes in neurons during cognitive tasks.
Event-Related Potentials (ERP)
- High temporal resolution captures electrical activity related to specific events.
Functional Magnetic Resonance Imaging (fMRI)
- Detects brain activity by measuring changes in blood flow (BOLD signal) during cognitive tasks, offering high spatial resolution.
Positron Emission Tomography (PET)
- Uses radioactive tracers to visualize active brain areas during tasks; has poor temporal and spatial resolution.

Additional Research Methodologies

Transcranial Magnetic Stimulation (TMS)
- Temporarily disrupts specific brain regions to assess cognitive changes.
Experimental Psychology
- Compares conditions to find systematic differences, using independent and dependent variables to measure accuracy and latency.

Mental Chronometry

Examines the time taken for different cognitive processes to reveal underlying differences among tasks.

Ecological Validity

The relevance of experimental findings to real-world behavior is measured by ecological validity.

Finding and Reading Empirical Articles

Empirical articles report original research and are structured with an abstract, introduction, methods, results, and discussion.
Utilize databases like PSYCInfo, Web of Science, and Google Scholar for research.

How to Search Effectively for Research

Refine search terms to narrow down results; broader terms yield excessive results.
Focus on specific phrases for more manageable article selections.

Understanding Article Sections

Read the abstract first to determine relevance and interest.
The introduction provides essential background and research questions.
