(Hindbrain + Midbrain)

What is Hypnotic susceptibility?

Individual differences

10% of population is meant to have high hypnotic susceptibility

What are the 4 effects produced through hypnosis?

Anaesthesia
Sensory distortions and hallucinations
Disinhibition
Posthypnotic suggestions and Amnesia

What is Hilgard’s Theory?

to explain the altered state of consciousness or awareness was that hypnosis creates a dissociation in consciousness

What is Dissociation in regards to Hilgard’s Theory of Hypnosis?

Dissociation: is a splitting off of mental processes into two separate, simultaneous streams of awareness
Example from everyday life: “Highway hypnosis”

What are Anaesthesia examples of the Hypnotic Phenomena?

Anaesthesia:

Hypnosis used in minor surgery and by dentists for pain management
Particularly useful with burns patients undergoing debridement
During pregnancy and Labour

What are the Behavioural Change examples due to the Hypnotic Phenomena?

Behavioural Change

smoking
Diet

What are the 2 types of Hypnotic Phenomena?

Anaesthesia | Behavioural Change

What is Meditation?

Practices that train attention to heighten awareness and bring mental processes under greater voluntary control

What are examples of Meditation and their benefits?

Yoga Zen Transcendental Meditation (TM) -Potential Physiological benefits - similar to effective relaxation procesudres

What are the Physical and Biological effects of meditation?

Alpha waves and Beta waves become more prominent ni EEG recordings

What 5 things does a decreased arousal lead to?

``` Decline in: Heart Rate Skin Conductance Respiration rate Oxygen Consumption Carbondioxide Elimination ```

What are the Benefits of Meditation?

Reduced effects of stress Improved mental Health Positive effects on other elements

What are the benefits of Meditation in regards to Reduced effects of stress?

Lower levels of stress hormone | Enhanced immune response

What are the benefits of Meditation in regards to improved mental health?

Reduced anxiety and concomitant reduction in drug abuse

What are the 4 Benefits of meditation in regards to positive effects on other elements?

``` 4x Positive effects of: Blood pressure Self-esteem Modd Sense of Contol ```

What is the Subliminal Perception?

The perception of stimuli below the threshold of consiousness

What has research determines in regards to Subliminal Perception?

Presenting people with Subliminal Stimuli (positive or negative) can influence their emotional reactions and behaviours

What are circadian rhythms?

a cyclical biological process that evolved around the daily cycle of light and darl

When do Foetuses begin to show circadian rhythms of sleep and activity?

six months gestational age

What do Circadian rhythms sometimes account for?

difficulties people experience when crossing time zones "Jet Lag" Work night shift - "health professions"

What do Circadian rhythms impact on?

Physical and Mental Health | Grades

What can Circadian Rhythms lead to changes in?

energy level mood efficiency through the day

What is the Physiological pathway of circadian rhythms?

Light levels --> Retina --> Suprachiasmatic Nucleus of the Hypothalamus --> Pineal Gland --> Secretion of Melatonin

What happens when people are in the absence of outside cues?

Peoples fall into a 25hour rhythm- (outside cues draw us into a 24 hr rhythm)

What are the Results of changing times zones too quickly for circadian rhythms to change?

Faster resynchronisation when West bound

What are the 2 Circadian rhythms?

Realigning them with Melatonin | Bright Lights

What are the 2 Circadian Rhythms associated with Mental Illness?

Mood disorders | Bipolar disorders
