Study Notes

Instinctive Drift

Breland and Breland observed that animals sometimes revert to instinctive behaviors despite conditioning efforts. This is known as instinctive drift.
Shaping is effective in modifying animal and human behavior.

Behavior Modification

A systematic approach to changing behavior utilizing principles of operant conditioning.
Used to teach new skills.
Can be used to modify undesirable behaviors
Learned helplessness occurs when individuals repeatedly encounter inescapable punishment, leading to a failure to escape in future situations.
Example: Rats failing to escape a foot shock, even when an escape route is available, after experiencing inescapable tail shocks.

Observational Learning and Aggression

Albert Bandura's research suggests that children learn aggression through observation.
Children who watched a film of a woman beating up a Bobo doll were more likely to be aggressive with the doll. This is called vicarious learning.
Mirror neurons are brain cells that fire when we perform an action and when we observe others performing the same action.

Encoding Information into Long-Term Memory

Rehearsal helps transfer information from working memory to long-term memory.
Understanding the meaning of information, elaborating on it, and making it personally relevant improves encoding.
Mnemonic devices help encode information, such as chunking and the PQRST method.
Schemas help organize new information into categories based on previous experiences and learning.
Spaced practice, where rehearsal sessions are spread out over time, helps the encoding of material.

Forms of Encoding

Phonological code relies on repeating sounds, such as repeating number sequences.
Visual code involves holding an image of the information, like remembering the visual appearance of digits.
Semantic codes link new information to previously stored knowledge, creating meaningful connections.
State-dependent memory is facilitated by being in the same state of mind as when the information was encoded.

Emotional Memory

Emotional events, whether positive or negative, are more readily encoded and remembered.
The modulation hypothesis proposes that the amygdala, during emotional event encoding, influences long-lasting emotional memory effects.
Flashbulb memories are detailed and enduring memories concerning the circumstances surrounding an emotionally significant event or learning about a major event.

Theories of Forgetting

Decay theory suggests that memories fade over time due to neglect or lack of access.
Interference theory attributes forgetting to competing information learned before or after the target information.
Proactive interference involves prior information interfering with the recall of new information.
Retroactive interference involves new information interfering with the retrieval of previously learned information.
Motivated forgetting involves unconsciously suppressing unpleasant or distressing memories, known as repression.

Distorted or Manufactured Memories

Memory distortions occur through source misattribution, where information is remembered but the source is forgotten, potentially leading to accepting information from unreliable sources as true.
Exposure to misinformation can cause retroactive interference, leading to forgetting information replaced with new, competing information.
Imagination can also influence memories, even creating false memories.

Memory and the Brain

Memory is a process, rather than a specific location.
The prefrontal cortex plays a crucial role in working memory.
The hippocampus is critical for transferring memories into long-term storage.
Memory consolidation involves stabilizing memories in the brain.
Potentiation occurs when networks of cells fire synchronously, strengthening connections and potentially contributing to memory formation.

Long-Term Potentiation (LTP)

LTP is a phenomenon where repeated stimulation of specific neurons in the brain dramatically increases the likelihood of strong responses to future stimulation.
Glutamate is a key neurotransmitter involved in memory formation.

Memory Development

Children develop memory capabilities gradually, with early memory largely tied to emotional experiences.
Prospective memory is the ability to remember information for future use.
Retrospective memory is the ability to remember past information.
The hippocampus develops slowly, impacting the development of memory.

Disorders of Memory

Amnesic disorders involve significant memory loss as the primary symptom.
Retrograde amnesia affects recall of events that occurred before the onset of amnesia.
Anterograde amnesia impairs the ability to form new memories after the amnesia-inducing event.
Dementias involve severe memory problems alongside other cognitive function decline.
Mild Neurocognitive Disorder (MND) involves moderate cognitive decline but limited impact on daily activities.

Alzheimer's Disease

Alzheimer's disease involves progressive memory impairments, attention lapses, language difficulties, and difficulty with complex tasks.
Neurofibrillary tangles are twisted protein fibers found within cells in the hippocampus and certain brain areas.
Senile plaques are spherical deposits of a protein called beta-amyloid, found between cells in the hippocampus, cerebral cortex, and other brain regions.

Gender and Dementia

Older women are more likely to develop dementia than men.
Certain health conditions, including depression and diabetes, increase dementia risk in women.
Women with Alzheimer's disease have more neurofibrillary tangles compared to men.

Sensation and Perception

Sensation is the process of using sensory systems to detect environmental stimuli.
Perception is the conscious recognition and identification of these stimuli.
Synesthesia is the involuntary and consistent mixing of senses, resulting in a person experiencing one sense through another (for example, tasting colors).
Sensory receptor cells are specialized cells that convert specific forms of environmental stimuli into neural impulses.
Sensory transduction is the process of converting environmental stimuli into neural impulses.
Absolute threshold is the minimal amount of stimulation needed to detect a stimulus, and it varies from person to person.
Difference threshold is the minimal difference between two stimuli required to detect a difference between them.
Signal detection theory suggests that our response to a signal depends on our ability to differentiate it from background noise.

Sensory Adaptation

Sensory adaptation is the process where repeated stimulation of a sensory cell leads to a reduced response.
Olfactory adaptation occurs when continuous exposure to a particular odor leads to a decrease in its detectability.

Smell Processing

Bottom-up processing begins with physical stimuli and progresses through transduction into neural impulses. These are sent to the piriform cortex for recognition.
The piriform cortex can adapt based on experiences, allowing us to learn to distinguish similar smells through conditioning (e.g., associating a smell with a shock).
Emotional connections are established through the olfactory bulb, which sends signals to the amygdala (emotions) and indirectly to the hippocampus (memory), explaining why certain smells can trigger memories.

Taste Processing

Taste receptor cells connect to sensory neurons on the tongue, sending signals to the thalamus and then to the cerebral cortex.
The thalamus acts as a relay station for most senses (excluding smell).
Pleasant tastes (sweet and salty) activate similar brain areas, whereas unpleasant tastes (bitter and sour) activate different areas.
Taste and smell are processed separately but converge in the prefrontal cortex.
The insula cortex processes taste and is linked to feelings of disgust, activating in response to unpleasant tastes, smells, and even repulsive images.

Development of Smell and Taste

Newborns can recognize their mother's scent within hours of birth and show a preference for her amniotic fluid odor.
After birth, babies quickly learn the smell of their mother's milk, which acts as a calming agent.
Newborns have a well-developed sense of taste, preferring sweet flavors and disliking bitter and sour ones.
Children begin to prefer sour tastes around age 7.
Bitter taste aversion typically persists until young adulthood, possibly leading to the enjoyment of foods like dark chocolate.
Taste buds develop before birth, with newborns having more than adults.
Children have taste buds in more areas than adults (palate, cheeks), potentially contributing to picky eating.
The high number of taste buds in children makes certain flavors seem stronger, helping them avoid potentially harmful substances.

Individual Differences in Smell and Taste

Sensitivity to smells varies widely among people due to genetics and environmental factors.

Hearing

Sound waves activate different regions on the basilar membrane based on their frequency.
Absolute pitch refers to the ability to recognize or produce any note on a musical scale.

Sound Adaptation

Adaptation occurs when we become less sensitive to continuous sounds with repeated exposure, as hair cells become less responsive.
General loudness serves as a cue for distance estimation, as we associate louder sounds with closer proximity.
Loudness in each ear aids in sound localization, as differences in loudness between the ears indicate the source's position.
Timing of sound arriving at each ear is another cue for sound localization, as the closer ear receives the sound wave first.

Development of Hearing

Fetuses are capable of transducing sound waves before birth.
They respond to loud noises with a startle reflex and can recognize some sounds from within the womb, like their mother's voice.
