Study Notes
Biological Basis of Behavior
- Neurons have dendrites, axons, and synaptic terminals
- Synaptic communication is the process of communication between neurons
- Action potentials involve ion movements (depolarization, resting potential, threshold)
- Neurotransmitters like GABA (inhibitory) and glutamate (excitatory) are crucial
- The brain has central and peripheral nervous systems with specific lobes and functions
- Language areas include Broca's and Wernicke's areas
- The corpus callosum connects the brain hemispheres in typical brains
- The limbic system includes structures like amygdala and hippocampus with specific functions
- The thalamus, hypothalamus, hindbrain (cerebellum, pons, medulla, reticular formation), and midbrain have primary functions
- Sensory systems transduce various energy types (e.g., sound, light)
- Perception involves transduction from sensory input to neural signals
Sensation and Perception
- Sensation and perception are distinct processes
- Transduction is the conversion of sensory input to neural signals
- Sensory systems (e.g., visual, auditory) have specialized receptor cells
- Visual system includes cones, rods, and aspects of the eye structure and processes
- Perception includes various factors, such as bottom-up and top-down processing as well as Gestalt principles
Memory and Attention
- Memory involves encoding, consolidation, and retrieval processes
- Long-term potentiation (LTP) plays a role in consolidation
- Memory processes are often associated with sleep
- Specific brain structures (e.g. Amygdala, Hippocampus) are involved in particular types of memory
- Selective attention and change blindness are aspects of attention
Abnormal Psychology
- Mental disorders have primary features like anxiety, depression and OCD
- The difference between anxiety disorders like specific phobias and generalised anxiety disorder (GAD) is important to know
- Depressive disorders can be unipolar or bipolar. Different types of bipolar are differentiated
- Understanding of schizophrenia, hallucinations, delusions, positive vs negative symptoms, along with biological theories like dopamine's role are required
- Trauma and Resilience related to the HPA-axis, and the role of the amygdala, hippocampus, PCC, and PPC are important
- Epigenetic changes and their relevance to trauma
Other Topics
-
Evolutionary Psychology (psy102-6X only): Natural selection, sexual selection, K-species versus R-species, intrasexual and intersexual competition, and mating strategies are included
-
Stress includes appraisal of stressors and cognitive reappraisal
