3 parts of spotlight or zoom lens model
Middle is focal point, fringe is next and last is margin
The 3 theories of selective attention
- Broadbents early selection theory
- Deutsch + Deutsch late selection theory
- Treisman’s attenuation theory
The 4 components of broadbents early selection theory and D+D late selection theory
Sensory register
Perceptual processes
Selective filter
Other cognitive processes
What differs between broadbent early selection and D+D late selection theories
Broadbent thinks that the selective filter comes first before the perpetual processes while D+D thinks the selective filter is after the perpetual processes (where words are assigned meaning)
So broadbent goes like this
Sensory register —> selective filter —> perceptual processes —-> other cognitive processes or working memory
While
D&D goes like this:
Sensory register —> perceptual processes —-> selective filter —> other cognitive processes or working memory
What is Treisman’s attenuation theory
Treisman follows broadbent’s order but instead of a selective filter you have an attenuator, the attenuator weakens but doesn’t eliminate the input from the unattended ear and some of it goes to the perceptual processes and is still assigned meaning but just isn’t high priority, at this point if you realize that the attenuated information is actually important (like hearing your name) you’ll switch ears/attention and attenuate (weaken) what you were previously listening to
Two attention networks and what they’re also known as
Dorsal attention network (endogenous attention)
Ventral attention network (exogenous attention)
Dorsal attention network
- voluntary, sustained and focused attention, you ignore distractions and is bilaterally distributed
-e.g concentration on reading a book in a noisy cafe, ignoring background conversations - dorsal means sensory to try to remember it as you want to focus your senses
Ventral attention network
- Alerting, detection of salient stimuli (which is stimuli that automatically captures your attention such as your name) or re-direction of attention
- relatively laterialized to right hemisphere
- e.g hearing a car horn while crossing the street which redirects your attention
- try to remember it as that ventral means motor and motor moves ur head to the sound
Piaget’s stages of cognitive development
-sensorimotor stage (0-2)
-pre-operational (2-7)
-concrete operational (7-11)
-formal operational (11+)
Sensorimotor stage
Age 0-2
Children want to explore world with their senses
Object permanence developed here
Pre-operational stage
- age 2-7
- children start to engage in pretend play - start understanding the meaning of symbols
- egocentric
Concrete-operational stage
- age 7-11
- where children learn the idea of conservation (water cup test)
- start to understand mathematics
Formal operational stage
- age 11+
- when children can reason about abstract concepts and think about consequences of potential actions
- sophisticated moral reasoning begins to take place
3 stages of memory
Encode (done by focusing attention)
Storage (short term and long term memeory)
Retrieval (Recall which is accessing memory with no cues and Recognition which is with cues)
What are the theories of memory
- The multi-store model (main one which the others are built on)
- levels of processing model ( more in depth encoding stage)
- working memory theory ( more in depth short-term memory stage)
- types of long term memory (more in depth long-term memeory stage)
What is the working memory theory
An elaboration of the idea of short term memory, Baddeley split short term memory into a central executive function which drives the whole system and does cognitive tasks like problem solving and allocates different attentional resources to 3 different components which are:
Phonological loop (inner voice which deals with spoken or written information)
Vision-spatial sketchpad (responsible for information in a visual or special form like inner eye)
Episodic buffer (links information together into the memeory we have of an event like the smell of the soil on a day of a funeral for example, it puts the elements in chronological order so memories are experienced like a story)
What is the levels of processing model
Proposes that there are levels of processing (encoding stage) for processing memories. E.g rehearsing and repeating creates stronger/more extensive neural connections than information we just pass by, or suggests that for a memory to be transferred into a stronger memory it must have meaning and be understood
