Sen, Percep & Memory
Psychology 1010
| Question | Answer |
|---|---|
| The process of organization, identification, and interpretation of a sensation in order to form a mental representation is called: | perception. |
| All the senses rely on the process of: | transduction |
| The absolute threshold is the: | minimal intensity needed to just barely detect a stimulus. |
| The just noticeable difference (JND) is the: | minimal change in a stimulus that can just barely be detected. |
| If you forget to take out the trash for two weeks, it will probably stink. After thirty minutes of being around it, you don't notice the smell. This is an example of: | sensory adaption |
| Sensation and perception: | are related but separate processes |
| Methods that measure the strength of a stimulus and the observer's sensitivity to the stimulus are called: | psychophysics |
| Which sense involves transducing changes in air pressure? | hearing |
| The minimal intensity needed to just barely detect a stimulus is called the: | absolute threshold. |
| Sensation occurs: | as the body interacts with the physical world. |
| Sensation and perception are related, but separate, events. | True |
| Perception does not begin until transduction has occurred. | true |
| Signal detection accounts of perception assume the existence of thresholds. | False |
| An organism's sensitivity to prolonged stimulation tends to increase over time. | false |
| The colored portion of the outer eye is called the cornea. | Iris |
| Cones are much more sensitive to low levels of light than are rods. | false-they adapt to bright light |
| The axons of retinal ganglion cells form the optic nerve. | true |
| The three primary colors of light are red, blue, and yellow. | False they are red, green and blue |
| Perceptual constancy means that humans are more likely to detect changing environmental stimuli than a constant stimulus. | False-we see familiar objects having standard shape, size & color |
| When confronted with two or more possible interpretations of an object's shape, we tend to perceive the simplest one. | true |
| The portion of the temporal lobe that contains the primary auditory cortex is termed area A1. | true |
| What part of the brain retains information to be transferred into memory? | Hippocampus |
| The organ of auditory transduction is the cochlea. | true |
| The basilar membrane lines the auditory canal. | False it is the cochlea |
| Pheromones that affect sexual behavior activate neurons in the hypothalamus. | True |
| Although the term used is “absolute threshold,” 50 percent of the time a signal at this level goes undetected. | True |
| The ability to store and retrieve information over time is called: | memory |
| _____ is the process of maintaining information in memory over time. | storage |
| The process of bringing to mind information that has been previously encoded and stored in memory is known as: | retrieval |
| The process by which we transform what we perceive, think, or feel into an enduring memory is called: | encoding |
| Memories are made by: | combining existing information in the brain with new information from our senses. |
| Actively relating new information in a meaningful way to knowledge already in memory is the definition of _____ encoding. | semantic |
| Storing information by converting it into mental pictures is known as: | visual imagery encoding. |
| The encoding of survival-related information is effective because it often requires participants to engage in: | extensive planning. |
| The store of auditory information that decays very rapidly is called _____ memory. | echoic |
| The fast-decaying store of visual information that is forgotten in seconds if not attended to is known as _____ memory. | iconic |
| Iconic memories usually decay in about _____ or less. | 1 second |
| Echoic memories usually decay in about: | 5 seconds |
| Short-term memory is limited in how long it can hold information and in the _____ information it can hold. | amount of |
| How much can we hold in memory at one time | 7 items |
| Combining small pieces of information into larger clusters is known as: | chunking |
| Short-term memory is to working memory as: | place is to process |
| In correct chronological order, we encode, retrieve, and store memories. | False-encode first, then retrieve and finally store memories |
| Memories are constructed, not recorded. | true |
| Often, semantic encoding occurs without conscious effort. | true-use of sensory input that has a specific meaning or is applied to context |
| Survival-related information is easily encoded into memory precisely because little or no planning is needed to encode biologically relevant information. | false-survival-related information results in higher levels of recall than the rest of the encoding methods mentioned. Survival encoding draws on elements of elaborative, imagery, and organization |
| Without rehearsal, short-term memory fades in less than 30 seconds. | true |
| Long-term memory has no known capacity limits. | true |
| Surgeons removed the hippocampus and portions of HM's medial temporal lobes in an effort to stop seizure activity. | true |
| Anterograde amnesia would prevent a patient from retrieving information that occurred a year before the date of the injury or operation that resulted in the amnesia. | false-loss of ability to create a new memory |
| Long-term memories tend to be stored in the hippocampus. | false-the hippocampus is for short term memory, the frontal lobe is for long-term memory |
| The amygdala is involved in the consolidation of emotional memories. | true |
