psych- AOS2 Flashcards
what is attention
refer to actively focusing on particular information while simultaneously ignoring other information. This includes ignoring internal and external stimuli.
what are the 3 types of attention
- sustained
- divided
- selective
what is sustained attention and give example
sustained attention refers to focusing on one stimuli or task across a prolonged or continuous period of time. It makes it possible to concentrate in order to complete a set task or to attend to something for a specific period of time.
- holding a conversation with someone for a few minutes
- shopping for a perfect pair of shoes online
- watching an episode of a TV series or watching a movie
what is selective attention and give an example
selective attention involves exclusively focusing attention on a specific stimuli or task while ignoring all other stimuli or tasks.
- being at a crowded party (focusing on the conversation)
- reading a book (in a busy coffee shop and concentrating on the words and storyline)
what is divided attention and give example
divided attention involves distributing one’s attention to allow for the processing of two or more stimuli at the same time.
- driving the car and talking on the phone at the same time
what is visual perception
Visual perception refers to the brain’s ability to make sense of what the eyes see.
what is gustory perception
gustation is the technical term for the sense of taste.
what is top-down processing
top down processing is a cognitive process that starts with the brain’s expectations, knowledge, and prior experiences to interpret and make sense of sensory information.
- this involves using content, background information, and understanding to perceive and understand stimuli.
what is bottom-up processing
bottom-up processing is a cognitive press that begins with sensory input, where perception starts with the incoming stimulus, building up to a final representation in the brain.
- starts with our sense picking up information from the environment. this sensory data is then put together to make sense of what we’re experiencing.
what is binocular depth cues
binocular depth cues require both eyes to send information to the brain to perceive depth. individuals with sight in only one eye are therefore unable to use these depth cues and thus will not be able to perceive depth to the same extent as someone using both eyes.
what are the two main binocular depth cues
- convergence
- retinal disparity
what is convergence and give example
convergence involves the inward turning of the eyes which is detected by the brain as tension changes in the muscles surrounding the eye.
- the eye turn inwards to focus on objects that are close, this stronger muscle tension to keep it in focus.
the further away an object, the less inward turning of the eyes and less muscle tension.
what is rential disparity
Retinal disparity is the slight difference in the images seen by each eye due to their horizontal separation. This difference helps the brain perceive depth and three-dimensional structure, allowing us to judge the distance of objects.
what are monocular depth cues
monocular depth cues require only one eye to send information to the brain to perceive depth.
what are psychological factors in visual perception
- past experience
- memory
- motivation
- context
what is perceptual set
refers to a psychological framework that influences how individuals perceive sensory information. Each personals perceptual set is different and shapes how they perceive stimuli. It is informed by your past experiences and memory, your motivations, and the context in which you are experiencing the stimuli.
what is past experience
the situations and events we have encountered throughout our lives prior to the present.
what is memory
the system that activity receives, organises, stores, and recovers information.
- Our memory is shaped by our experiences of the world, and it helps us understand how our world works.
- It plays an important role in our expectations of how the world should operate..
what is motivation
Motivation is defined as the process that initiates, guides, and sustains goal-oriented behaviours. Depending on our motivation, we will perceive certain stimuli that aligns with our gals as more salient than others.
what is context
Context is the situation, or condition in which something occurs. Content informs our perceptual set, affecting how stimuli are perceived including visual stimuli.
what is percepual constancy
The mind’s ability to perceive a stimulus as being the same, constant even though they may look a little bit different.
what are the 3 types of perceptual constancy
- size constancy
- shape constancy
- orientation constancy
what is shape constancy
Shape constancy occurs when an individual recognises that a stimulus actual shape remains the same despite changes in the shape of the retinal images sent to the brain.
what is size constancy
Size constancy occurs when an individual recognised that a stimulus actual size remains the same despite changes in the information sent to the brain about the size of the stimulus.
what is orientation constancy
Orientation constancy occurs when an individual recognised that a stimulus action orientation remains the same despite changes in the orientation of the retinal impacts sent to the brain.
