internal mental processes should be studied scientifically
focuses on
how mental processes affect behaviour
development of first computer gave psychologists a metaphor for describing
inside peoples mind
areas such as memory and perception and thinking can be studied indirectly by making inferences
internal mental processes
humans are information processors
main concern of approach is how info received from our sensors is processed and how it directs how we behave
e.g perception, memory, thinking, attention, language
inference
act of drawing conclusions from evidence and reasoning
clues from observing behaviour to build explanations of what's going on in unobservable part of brain
multi-store model of memory
flows through a set of stages that involved
input , storage and retrieval
Multi-Store Model of Memory
The model explains how information is stored and retrieved from memory, with sensory memory, short-term memory, and long-term memory as its key components
computer models
compared to a computer
similarities in ways that we process
e.g. CPU = brain , info (input) a person receives behaviour is output
brain = hardware , processes = hardware
coding = info changed into useable format (electrical signals)
schema
a mental framework of beliefs and expectations that influence cognitive processing and help us to interpret our world
developed from our experiences, upbringing and culture
pros of schemas
efficiently process and organise vast amount of info and respond to situations quickly
reduces cognitive load, allow quick-decision making by filling in gaps with past knowledge
provide structure to memory and learning, can form predictions and can navigate complex or familiar situations
cons of schemas
lead to cognitive biases, rely to heavily on past experiences and expectations can distort new info to fit frameworks
stereotyping or overlooking details that don't align with schemas
limitsflexibility and accuracy
hinder ability to adapt to unique or unfamiliar situations
can't interpret behaviour that doesn't align with existing beliefs
method and findings of Bartletts study
1932 pps asked to read Native American folk tale
and recall several times over varying intervals
findings showed recollections of stories became shorter and simpler over time
altering unfamiliar details to fit their own cultural expectations
concluded that memory is reconstructive, actively reshaped info based on schema
memory is influenced by personal biases
emergence of cognitive neuroscience
study of influence of brain structures on mental processes
in 1860Paul broca identified how damage to an area of the frontal lobe could permanently impair speech production
advances in brain technology
e.g. fMRI and PET scanning
in last 25yrs scientists have been able to describe the locations and neurological basis of mental processing and of disorders
in OCD
PET scans indicate high activity in orbital frontal cortex
a brain area associated with higher though processes and conversion of sensory info into thoughts
research of long-term memory
research involving tasks that required us of episodic , semantic and procedural memory
researchers were able to show how these different types of LT memory may be located in different parts of the brain
computer generated models
cognitive neuroscience has expanded
models designed to 'read' the brain
one application could be to analyse the brain wave pattern of eyewitnesses to see if they're lying in court

cognitive neuroscience
the study of brains processes and structures
evaluation: Machine reductionism
criticised because it composers the human mind to a computer, focusing on the information processing and neglecting the influence of emotions and individual differences
this may be an issue because human cognition is far more complex and flexible than a computer can represent and count for
therefore, this analogy limits the approaches accuracy and usefulness as it may overlook essential factors that influence real-life cognitive processes leading to an incomplete understanding
evaluation: real-world application
a major strength is its application in developing CBT therapies, an effective treatment for various mental health disorders including depression and anxiety
this is advantageous because CBT helps individuals identify and modify dysfunctional thought patterns by applying cognitive principles
therefore, this approach demonstrates practical value by not only explaining cognitive processes but also offering therapeutictechniques that make a positive impact on individuals
evaluation: use of scientific and objective methods
relies carefully on controlled lab research to infer mental processes
this is beneficial because lab studies allow researchers to isolate specific variables and establish a cause-and-effect relationship, lending credibility and rigor to cognitive theories
therefore, gains scientific respectability and produces findings that can be tested and replicated
