b) Self…hypnosis is the best approach to controlling pain because 

91 


PSYCHOLOGY AND LIFE 

individuals can essentially self…medicate whenever pain 

arises 

c) Research on hypnotic pain reduction suggests that hypnosis 
segregates consciousness into two levels。 One level is a full; 

but hypnotic; consciousness。 The second level is a Hidden 
Observer; a concealed nonconscious awareness that monitors 
the hypnotized consciousness。 

d) People cannot be made to do anything that they do not wish 
to do under hypnosis 

C。 Meditation 
1。 Meditation is a form of consciousness change designed to enhance self…
knowledge and well…being by reducing self…awareness 
a) Critics argue that there is little difference between a normal 
resting state with the eyes closed and the state entered 
through meditation 

b) Advocates argue that meditation reduces stress; can improve 
IQ; and can even lead to enlightenment 

D。 Hallucinations 
1。 Hallucinations are false perceptions that occur in the absence of 
objective stimulation and can be caused by the following: 
a) Heightened arousal 

b) States of intense need 

c) Inability to suppress threatening thoughts 

d) Abnormal brain functioning caused by fevers; seizures; and 
migraine headaches 

e) Psychoactive drugs; such as LSD and peyote; can also 
produce hallucinations by acting directly on the brain 

2。 In some cultural and religious settings; hallucinations play an 
important mystical or spiritual role 
E。 Religious Ecstasy 
1。 Religious ecstasy is a unique psychological state characterized by a 
sense of oneness and connectedness often brought on by meditation; 
prayer; fasting; and spiritual munication 
2。 During religious ecstasy; some individuals can do remarkable things 
that they ordinarily may not be able to do; such as handling deadly 
snakes; drinking poison; and handling fire 
F。 Mind…Altering Drugs 
1。 Although mind…altering drugs have been used for centuries during 
religious ceremonies; today they are associated more often with 
92 


CHAPTER 6: MIND; CONSCIOUSNESS; AND ALTERED STATES 

recreational usage 

2。 Dependence and Addition 
a) Psychoactive drugs are chemicals that affect mental processes; 
such as perception; memory; mood; and behavior by 
temporarily changing conscious awareness 

b) Tolerance may be developed to psychoactive drugs in which 
more and more of the drug is needed to produce the same 
change in consciousness 

c) Physiological dependence is a process in which the body 
bees accustomed to the presence of a drug and begins to 
depend on its presence to function properly 

3。 Varieties of Psychoactive Drugs 
a) Hallucinogenic or psychedelic drugs; including LSD; mescaline; 
psilocybin; and PCP; can produce profound alterations of both 
perception and inner awareness。 They often lead to a loss of 
boundary between self and non…self and to confusion。 

b) Cannabis; including both marijuana and hashish; can create 
mild; pleasurable highs; distortions of space and time; 
euphoria; and; occasionally; hallucination。 Possible negative 
effects include fear; anxiety; paranoia; confusion; and 
retardation of motor function。 

c) Opiates; such as heroin and morphine; suppress physical 
sensation and stimulation and produce a rush of euphoria。 
Because of this rush; any use is likely to lead to serious 
addiction。 

d) Depressants; such as barbiturates and alcohol; tend to depress 
the mental and physical activity of the body by inhibiting the 
transmission of nerve impulses in the central nervous system 

(i) Barbiturates; such as Valium and Xanax; are 
particularly dangerous; accounting for half of drug 
overdoses 
(ii) Although often socially accepted; alcohol is a major 
health and social problem。 Alcohol use can lead to 
alcoholism; which can disrupt social and 
professional relations; and to serious health 
problems。 
e) Stimulants; such as amphetamines; cocaine; and crack (a purified 
form of cocaine); induce a sense of euphoria; self…confidence; 
and hyperalertness。 Possible negative effects include 
paranoid delusions; cycles of euphoric highs and painful 
lows; and social isolation。

PSYCHOLOGY AND LIFE 

(i) Caffeine and nicotine are often unrecognized 
stimulants that act on the brain much like other 
stimulants。 Nicotine is a dangerous drug that has a 
greater impact on health than that of all other 
psychoactive drugs bined。 
DISCUSSION QUESTIONS 

1。 The class should now be familiar with dualism and monism; through both the text and 
lectures。 Ask them which of these they think best describes the relationship between the 
brain and the mind。 Why? Can anyone think of personal experiences or observations to 
support their beliefs? What about empirical data that might support a given hypothesis? 
2。 Zimbardo and Gerrig propose that sleep may have evolved because it gave animals an 
opportunity to conserve energy at those times when they did not need to be searching for 
food or a mate。 Given that we as humans no longer engage in these activities under the 
same constraints as animals; ask the class if they think it possible that we may eventually 
evolve out of the need for sleep。 
3。 According to Zimbardo and Gerrig; there appears to be a developmental timetable for 
dreams that parallels our cognitive developmental pathway; with children being the 
example given。 If this premise is valid; what sort of dreams might we expect to see at the 
opposite end of the spectrum; during old age? 
4。 Ask your students if they have ever had a lucid dream。 Have students share their lucid 
experiences。 Students find this subject fascinating; and the topic often leads to lively 
discussion concerning the nature of consciousness and the nature of reality。 How would 
students use the extra time of consciousness while they are lucid in their dreams? Would 
they use it differently than they would normal consciousness? Why or why not? 
5。 Most sleep researchers argue that people need an average of 8 hours of sleep per day to be 
fully rested and alert。 First; you might ask students why they think this is; as most people 
today do not physically exert themselves enough to require 8 hours of sleep to physically 
recharge themselves。 Second; you might ask students how much sleep they are getting each 
night。 My guess is most of them are not getting the remended 8 hours per night。 But 
many of them are probably not feeling overtired or sleep deprived。 While the average 
amount of required sleep is 8 hours; many people function quite well on 6 or 7 hours per 
night; while others need 9 or 10 hours per night。 I had a professor in graduate school who 
functioned quite effectively for years on only 3 or 4 hours per night! The important thing for 
94 


CHAPTER 6: MIND; CONSCIOUSNESS; AND ALTERED STATES 

students to know is that not everyone needs the average; but knowing how much sleep 
your body needs and adjusting your schedule so that you are getting what you need is 
crucial to feeling rested。 

6。 Many people sleep somewhat more when they are mildly depressed or experience mild to 
moderate stress。 Some students who are juggling school; work; and family/social life find 
that they are nodding off every time they sit down or relax; but are still consistently 
exhausted。 If they add up all the hours they are “napping;” it can add up to 11 or 12 hours 
a day。 Of course; it is not good quality sleep; which means it doesn’t help them feel 
“recharged” or well rested。 When I was a psychology intern at a university counseling 
center; it was such a mon phenomenon we began calling it “student sleep syndrome。” 
Often; students feel even worse when this occurs because they begin to wonder what’s 
wrong with them; which pounds their stress。 Most students are relieved to know that 
this condition is mon and often disappears when stress levels are reduced。 Usually; 
when a student takes a term off or cuts back on his or her schedule; the condition 
disappears。 However; as with any dramatic or prolonged change in energy level or 
physical condition; students should get a plete physical examination
