Psych Unit 1
Parts of the Brain
| Question | Answer |
|---|---|
| Frontal Lobe | Planning and higher order reasoning |
| Temporal Lobe | Hearing and Speech Comprehension |
| Parietal Lobe | Touch |
| Occipital Lobe | Vision |
| Cerebral Cortex | -Outer layer of brain tissue with many folds. -Responsible for complex mental activity. -Site of all thoughts. -Divided into 2 hemispheres (left and right) -Connector= corpus callosum |
| Cerebellum | -Controls balance -Coordinates movement -Damage can produce different effects ranging from balance problems to loss of limb coordination. |
| Brainstem | -Consists of medulla oblongata, pons, and the midbrain. -Brainstem is a continuous extension of the spinal cord. -Controls basic functions for survival (heart rate, breathing) -Significant injury to this area can result in death. |
| Theory | A model of interconnected ideas or concepts that explains what is observed and makes predictions about future events. |
| Hypothesis | A scientific prediction of what should be observed if a theory is correct. |
| Research | A scientific process that involves the systematic and careful collection of data. |
| Independent Variable | Variable that is manipulated by the experimenter to examine its impact on the dependent variable. |
| Dependent Variable | The variable that is affected by the manipulation of the independent variable. |
| Confound | Anything that affects a dependent variable and may unintentionally vary between conditions of a study. |
| Positive Correlation | As one variable increases, so does the other one. |
| Negative Correlation | One variable decreases, the other increases. |
| Correlations | Describes the strength and direction of the relation between 2 variables. |
| 7 Themes | Psychology is an empirical science Nature v. Nurture Brain and mind are inseparable Biological revolution is changing research Mind is adaptive Psychological science crosses levels of analysis Multiple influences of how we think, feel, and act |
| Central Nervous System | Brain and Spinal Cord |
| Peripheral Nervous System | All other nerve cells in the body |
| Occipital Lobes | At the back portion of the head. |
| Parietal Lobes | Left hemisphere receives information from the right side of the body. |
| Temporal Lobes | -Highly activated when people look at faces- especially right side up -Fusiform Face Area |
| Frontal Lobes | -Responsible for muscle movement. -Controls rational activity |
| Fusiform Gyrus | Area of the brain is most activated by right side up images. |
| Thatcher Effect | A phenomenon where it becomes more difficult to detect local feature changes in an upside-down face, despite identical changes being obvious in an upright face. |
| Hypothalamus | -Regulates vital body functions -Temperature regulations, appetite, sexual behavior -Receives and sends information to almost every part of the brain and body |
| Thalamus | -Gateway to the brain -Sensory relay- receives almost all incoming sensory information, organizes it, and relays to cortex. -Smell has a direct route to cortex. |
| Hippocampus | Formation of new memories |
| Amygdala | -Emotions- serves vital role in learning to associate things with emotional responses. -Evaluating facial expressions -Special role in responding to stimuli that elicit fear- hardwired for protection from danger. |
| Basal Ganglia | -Planning and producing movement -Receives input from cerebral cortex and sends to motor centers of the brain stem -Brains reward system -Damage can produce Parkinson's or Huntington's |
| Music | One of the only activities that activates, stimulates, and uses the entire brain. |
