What is selective attention how does it relate to the cocktail party effect?

By Sophia Heath


Consciousness­the awareness of ourselves and our environment

 Internal­awareness of self such as hunger and emotion

 External­awareness of outside factors such as sensory input and others  Salience­to be aware of something

Characteristics of Consciousness:

 Limited capacity for attention

 Attention is selective

 Focus is a spotlight where majority of focus goes

­The Cocktail Party Effect­rejecting things someone isn’t listening to when focusing on  something specific, like conversations at a cocktail party

How many hours are in one's circadian rhythm?

Change Blindness­don’t recognize a change in the environment

Dual track mind­dual processing­we process consciously and unconsciously 2 processing types:

 Parallel processing­processing multiple things at once

 Sequential processing­focusing on one thing at a time

 Cognition­mental processes

 Spontaneous states­daydreaming, drowsiness, dreaming

 Physiologically induced states­hallucinations, orgasm, food or oxygen starvation  Psychologically induced states­sensory deprivation, hypnosis, meditation

Sleep And Dreams

Circadian rhythms­naturally peak and dip through the course of 24 hours  Sleepiness­3 am/pm

How does environment affect sleep?

We also discuss several other topics like How does mucous membrane protect the body from infection?
Don't forget about the age old question of How did political parties begin in the us?

 Alertness­9 am/pm

 Sensory sensitivity­3am/6pm

 Pain sensitivity­lowest at 4pm, highest at 4 am

 Body temperature­lowest at 4 am, highest at 4 pm

­Controlled by our master biological clock in our Suprachiasmatic Nucleus(SCN) in  hypothalamus

Environmental cues affect sleep like:

 Light

 Melatonin production from the pineal gland

 Daylight savings time

 Jet lag or social jet lag

Purpose of sleep

1. Protects us at night

2. Helps us recuperate

3. Helps us restore/rebuild memory

4. Feeds creative thinking

5. Promotes growth Don't forget about the age old question of Why do bacteria die during the death phase?

 Sleep Deprivation: causes loss of concentration, inability to gauge risks, negative mood,  more cortisol, depression, weight gain

Sleep Stages:

1. Beta­alert, focused

Alpha­getting tired

Delta­going into sleep

2. NREM Stage 1­ transitional stage, alpha to theta

3. NREM Stage 2­theta wave, contains sleep spindles

4. NREM Stage 3­4­Deep sleep, delta waves

5.REM Stage­the dream stage

Theory of Dreams­

­Freud­wish fufillment

­John Allan Hobson­neurochemical changes in brain, reverse inlearning

Lucid Dreaming­A hybrid state of consciousness


Psychoactive drugs­chemicals that change brain function

Addiction­craving of reuse despite negative effects

Types of Drugs:

Alcohol­increases dopamine and GABA, lowers glutamate

 Effects: cerebral, cerebellum, hypothalamus, and the medulla

Stimulants­increase brain functioning

Caffeine­addictive, has pros and cons

Depressants­reduce brain functioning

Hallucinogens­experience sensory input when there is none/little We also discuss several other topics like What is a franchise agreement in business?

Antipsychotics­stop certain mental disorders

Psychedelics­ “mind­manifesting” subclass of hallucinogens

Development Issues, Prenatal Development, And Newborns Fetal development­

 Considered a fetus at 9 weeks

 6 months­ responsive to sound and can survive outside the womb

Epigenetics­changes in how we express our DNA rather than altering it, chemical flags Teratogens­variables that affect the growth of a fetus such as alcohol


1. Grasping

2. Rooting

3. Suckling

4. Startle

5. Plantar

Infancy And Childhood

1. nature/nurture­how genetic inheritance and experiences affect development 2. Continuity stages­development can be steady and continuous or sudden and abrupt 3. stability/change­which traits persist and which change as we age

Schemas­current understanding

Sensorimotor­learning from senses and actions

Preoperational­representing things with words, too young for mental operations concrete operational­can grasp operations like conservation and change
