What is **selective attention**?

• The ability to focus on multiple tasks simultaneously

• The ability to focus on one specific task or stimulus

• The inability to focus on any stimuli

• The ability to multitask without loss of focus

**Blindsight** refers to:

• The inability to see due to eye damage

• The ability to respond to visual stimuli without conscious perception

• The gradual loss of sight due to age

• The sensation of light with closed eyes

**REM sleep** is characterized by all of the following EXCEPT:

• Rapid eye movement

• Increased brain activity

• Muscle paralysis

• Sleepwalking

According to the **activation-synthesis theory**, dreams are:

• A reflection of unresolved conflicts

• The brain’s attempt to make sense of random neural activity

• A form of problem-solving

• A way to fulfill unconscious wishes

What is the **dual-processing model**?

• The brain processes information on both conscious and unconscious tracks simultaneously

• The brain can only process one task at a time

• The brain switches between conscious and unconscious states every 90 minutes

• The brain focuses on a single task and ignores unconscious stimuli

**Circadian rhythm** is:

• The 90-minute sleep cycle

• A 24-hour biological clock regulating sleep and physiological processes

• The cycle of REM and NREM sleep

• The rhythm of brain activity during sleep

**REM rebound** occurs when:

• You experience an increase in REM sleep after being deprived of it

• You lose all REM sleep for several nights

• You immediately fall into deep sleep after REM

• You skip REM sleep entirely

**Sleep apnea** is:

• A disorder causing uncontrollable sleep attacks

• A disorder where breathing repeatedly stops during sleep

Meditation typically results in:

• Increased physical activity

• Decreased alertness

• Shifted consciousness and relaxation

• Unconscious states

Inattentional blindness is:

• Failure to notice changes in the environment

• Failure to notice a visible stimulus when attention is directed elsewhere

• The inability to focus on a specific stimulus

• Blindness caused by sleep deprivation
