    Study Notes

    Divided Attention

    • Divided attention is splitting attention across two or more stimuli at one time.
    • Divided attention is involved in multitasking.
    • Humans are not as good at multitasking as they think.
    • Multitasking can make individuals prone to distraction and reduce their understanding of the task.

    Multitasking

    • Multitasking is inevitable, particularly when individuals feel they must complete two tasks at a time.
    • Multitasking is common when juggling a boring task with an interesting task.
    • Multitasking is common when actively learning.

    Negative Impacts of Multitasking

    • Multitasking prevents full potential on any one task.
    • Multitasking has negative implications when the task is not easy to resume.
    • Multitasking has negative implications when tasks are unrelated or completed on different platforms.
    • Multitasking has negative implications when tasks are complex or require full attention.

    Selective Attention

    • Selective attention involves focusing on a specific stimulus or task while ignoring all other stimuli or tasks.
    • Selective attention requires filtering out external stimuli like noise.
    • Selective attention requires filtering out internal stimuli like thoughts and emotions.

    Sensation and Perception

    • Sensation is the process by which sense organs and receptors detect and receive sensory information.
    • Sensory information is meaningless until it is sent to the relevant sensory area of the brain.
    • Perception is the process of interpreting sensory information.

    Top-Down Processing

    • Top-down processing involves prior knowledge and expectations influencing perception.
    • People use schemas for top-down processing.

    Bottom-Up Processing

    • Bottom-up processing involves sensory information being processed to form a perception.

    Visual Perception

    • Visual perception is becoming consciously aware of visual stimuli as a result of interactions between the visual sensory system and the individual's internal and external environment.
    • The visual sensory system includes the eyes, brain, and the neural pathways connecting them.

    Stages of Visual Perception - Selection

    • Only some visual signals are selected for processing.
    • The visual selection process is performed by feature detectors.
    • Feature detectors select and filter visual signals according to perceptually important features.

    Stages of Visual Perception - Organisation

    • Visual signals are regrouped and organized to reflect an image of reality.
    • Visual perception principles help with this.

    Stages of Visual Perception - Interpretation

    • The primary visual cortex works with other areas of the brain to interpret visual stimuli.
    • Interpretations are influenced by motives, beliefs, and perceptual set.

    Gustatory Perception

    • Gustatory perception is becoming consciously aware of flavor.
    • The tongue is the primary sensory organ for detecting gustatory information.

    Tastants

    • Tastants are sensory stimuli received in the form of chemical molecules.
    • Tastants are broken down by saliva.
    • Tastants are received by gustatory receptors located within taste buds.
    • Taste buds are clusters of gustatory receptors.

    The Brain and Taste

    • The brain processes information about the type and intensity of flavor in the primary gustatory cortex in the parietal lobe.

    The Five Basic Tastes

    • The basic tastes are sweet, sour, salty, bitter, and umami.
    • Different foods are associated with different basic tastes.

    Myths about Taste

    • The tongue is not divided into areas responsible for different tastes.
    • Taste buds are dispersed throughout the mouth.
    • Taste buds are more sensitive to certain tastes than others.

    Perception in Taste

    • Olfactory and somatosensory cortexes play a role in taste.

    Factors Influencing Visual Perception

    • Visual perception is influenced by biological, psychological, and social factors.

    Biological Factors

    • The eye
    • Color blindness
    • Short-sightedness
    • Depth cues

    The Eye

    • The eye receives light to enable vision.
    • Light enters the eye through the pupil and is focused onto the retina.
    • The retina contains photoreceptors which receive light and convert it into neural signals.

    Genetics and Taste

    • 25% of people are supertasters with an unusually high number of taste receptors.
    • 25% of people are non-tasters with an unusually low number of taste receptors.
    • The rest of the population are medium-tasters.

    Psychological Factors

    • Psychological factors that affect taste include perceptual set.
    • Perceptual set is influenced by appearance and food packaging.

    Perceptual Set

    • Taste is often shaped by expectations.
    • The appearance of food affects taste expectations.
    • The shape of food affects taste expectations.
    • Packaging, labeling, and branding affect taste expectations.

    Social Factors

    • Culture affects gustatory perception.

    Spatial Neglect

    • Spatial neglect is a neurological disorder where individuals cannot attend to anything on one side of space.
    • People with spatial neglect behave as if one side of their world does not exist.
    • Spatial neglect is caused by damage to the parietal lobe in the right hemisphere.

    Spatial Neglect and Perception

    • The problem in spatial neglect is that the patient is unable to pay attention to information received from one side of space, not a problem with sensation.
