What are images?
seemingly perceptual experiences that we hve iwthout the presence of an external source for the perception–the image come from inside us, from our ind’s eye
motoric imagery
when we mentally rehearse a dance or image making a great play on an atheletic field, images that have motor actions attached to them
haptic
such as when we imagine touching sandpaper, images that have touch sensation attached to it
difference betwee nhallucination and images
images are under our control and we do not experience them as coming from outside of us as happens with halluciantions
Can mental images be manipulated?
yes images can be manipulated to meet our goals, sich as trying to remember if we closed the door, or what way we should go
What is way finding
refers to the cognitive process people employ in a spatial environment in order to arrive at a goal
How can images help us remember?
It helps us remember when it is able to provide an association–a link–betwee nthe items that people are trying to remember.
What is analog code?
they are like maps or moving pictures; they preserve the rlatinship among the elements of the image as if a person were experiencing them directly. For example, a map captures the distanced and directions among locations; mercury thermometer expresses termperature continously as the height of liquid; a watch with hands indicated the passage of time with the angle the q2 and the small hand. The information conveyed by the physical system is abstract.
propositional code
propositions are the smallest unit ofk nowledge that can be either true or false. These images do not resemble the physical stimulus as a mental picture might; however, propositions can express the underlying meaning of the stimulus. A list of directions would be propositional code, while a map diagram would be an analog code
which one takes longer o scan, large or small distances on a map?
large distances take longer to scan, despite expecations; our spatial layout preserve the spatial relations, thus we are using an analog code to scan our images
limits to our ability to use images
images are not the same as when you have a figure infront of us, as our mental eye cannot find certain figures hidden within our images.
can you remember what was covered in class while remmebering what you have to do after class? Explain
no, becausae they are both demanding attention that reurie the same or overlapping cognitive resources, verbal processing
can humans mentally rotate 2-d and 3-d objects?
yes, this is called isomorphic, the ability to continously in a manner that is similar to the way we physically rotate objects are able to rotate images.
what is the symbolic distance effect
the more discriminable two real objects are, the more quikcly you are to be able to judge which is bigger or smaller.
As the size increase, the time to make the ____________ __________.
Judgement; decreases
which hemisphere of the brain is best at mental images?
the right hemisphere performs many functions important to the perception of spatial relations
do images cuase a neurological response as if the object were really there?
yes , it does, it acritivates the section in the right hemisphere that would also be important to the process of images
Mental rotation works best on what brain hemisphere?
the right hemisphere
small letters and large letters activate the same regions of the brain?
no, the do not. Large letters activate the front part of the occipital lobe, and the small ones the backmost part of the occipital lobe
do people with hemineglect have problems to process the left side of images?
yes, they do, because images activiate areas of the brain similar to actually observing an object, thus when thes areas fail to activate when imagining and image, the image’s left areas does not come to be as easily.
congenital blindness
blind from birth
do blind participants show the same imagery effects as sighted participatns?
yes, they do show the same effects as sighted participants. Thus, research has shown that blind people can mentally imagine objects, and manipulate them and show that mental rotation can operate on a spatial representiation that does not have any specifially visual components
what is reality monitoring
the ability to discriminate between genuine memories acquired from perceiving the external world from memories generated by the imagination
what are some characteristics of actual experiences?
they have more contextual details than recollections of imagined experiences.
