Sensory knowledge of the surrounding world – perception
Overall processes of apprehending

objects and events in the environment: sensing, understanding, recognizing, labeling
Percept –what is perceived – outcome of perception
Function of perceptual processes: survival and sensuality
Three stages of perception:
Sensation
Perceptual organization
Identification and recognition

Sensory knowledge of the surrounding world
Vision: image (the physical object in

the world: (distal stimulus) optical image on the retina (proximal stimulus)
Hearing - psychological dimensions:
Pitch: the highness and lowness of sound’s frequency
Laudness: physical intensity
Timbre: complex sound wave
Smell: odorant molecules interact with receptor proteins
Significant and powerful medium for interaction: pheromones
Taste: taste works together with smell in order for the gustation to be fully experienced
sweet, bitter, sour i salty
Umami (MSG present in meat, seafood and aged cheese)
Touch and skin senses
Sensations of pressure, warmth and cold

Слайд 4

Sensory knowledge of the surrounding world
Vestibular sense: orientation with respect to

gravity
Loss of vestibular sense may be compensated with vision
Kinesthetic sense: information about current position and movement of the body (stone example)
- Receptors in the joints
Receptors in the muscles and tendons
Pain: response of the body to stimuli which is harmful (human brains warn us of danger)
Network of pain fibers cover human’s entire body
Do people feel pain differnetly based on their current emotional state?

Perceptual processes network

Слайд 6

Organizational processes in perception (e.g. how does this thing look like?)
Integrating

data originating from our previous experiences
Attention processes (Focus on a subset of stimuli which you are aware of):
Goal-directed attention – choices made by an individual to direct attention to certain object
Stimulus-driven attention – objects in the environment capture our attention (daydreaming on the stoplight, spider on the wall)

Слайд 7

Peceptual grouping
Gestalt psychology – psychological phenomena can be understood only when

viewed as organized, strucutred wholes and not when broken down into elements
The whole is quite different to its parts.
Perceptual grouping laws:
The law of proximity.
The law of similarity
The law of good continuation
The law of closure
The law of common fate

Mind and consciousness
General state of mind– “being conscious”
Specific contents of mind

- “being conscious/aware”
Introspection – exploring the contents of the conscious mind
Ordinary waking consciousness - perceptions, thoughts, feelings, images, and desires at a given moment—all the mental activity on which an individual is focusing her attention.
Sense of self - experience of watching yourself from the “insider” position

Слайд 13

Processes of the consciousness
nonconscious processes
Blood pressure
breathing
preconscious memories
Functions

in the background of your mind, until you draw your attention to it and recall it
unattended information
Background noise
unconscious – not readily accessible to conscious awareness
Denial – repressing - banishing threatening memories of the experiences from consciousness
How can the contents of consciousness be studied ?

Слайд 14

What do we need the consciousness for? the functions of consciousness
Development

of consciousness allowed for better comprehension of information in order to plan the most appropriate and effective action:
Grand prize of survival of the fittest mind
Sensory-information overload:
Aiding in survival by
restricting what you notice and what you focus on from the flow of input
Selective storage – commitment to memory
Thinking through alternatives based on previous knowledge: planning

Слайд 15

Change in consciousness: sleep
circadian rhythm: arousal levels, metabolism, heart rate, body

temperature, and hormonal activity ebb and flow according to the ticking of the internal clock
mismatch between the biological clock and the sleep cycle affect how people feel and act
Night shifts
Jet legs: flying across time zones
Why people need to sleep?
