The End
• Types of Files
Teacher Information
– This presentation has been saved as a “basic” Powerpoint file. While this file
format placed a few limitations on the presentation, it insured the file would be
compatible with the many versions of Powerpoint teachers use. To add
functionality to the presentation, teachers may want to save the file for their
specific version of Powerpoint.
• Animation
– Once again, to insure compatibility with all versions of Powerpoint, none of the
slides are animated. To increase student interest, it is suggested teachers
animate the slides wherever possible.
• Adding slides to this presentation
– Teachers are encouraged to adapt this presentation to their personal teaching
style. To help keep a sense of continuity, blank slides which can be copied and
pasted to a specific location in the presentation follow this “Teacher
Information” section.
Teacher Information
• Hyperlink Slides - This presentation contain two types of hyperlinks. Hyperlinks
can be identified by the text being underlined and a different color (usually purple).
– Unit subsections hyperlinks: Immediately after the unit title slide, a page (slide
#3) can be found listing all of the unit’s subsections. While in slide show mode,
clicking on any of these hyperlinks will take the user directly to the beginning of
that subsection. This allows teachers quick access to each subsection.
– Bold print term hyperlinks: Every bold print term from the unit is included in
this presentation as a hyperlink. While in slide show mode, clicking on any of
the hyperlinks will take the user to a slide containing the formal definition of
the term. Clicking on the “arrow” in the bottom left corner of the definition
slide will take the user back to the original point in the presentation.
These hyperlinks were included for teachers who want students to see or copy
down the exact definition as stated in the text. Most teachers prefer the
definitions not be included to prevent students from only “copying down what
is on the screen” and not actively listening to the presentation.
For teachers who continually use the Bold Print Term Hyperlinks option, please
contact the author using the email address on the next slide to learn a
technique to expedite the returning to the original point in the presentation.
Teacher Information
• Continuity slides
– Throughout this presentation there are slides, usually of graphics or tables, that
build on one another. These are included for three purposes.
• By presenting information in small chunks, students will find it easier to process and
remember the concepts.
• By continually changing slides, students will stay interested in the presentation.
• To facilitate class discussion and critical thinking. Students should be encouraged to think
about “what might come next” in the series of slides.
• Please feel free to contact me at kkorek@germantown.k12.wi.us with
any questions, concerns, suggestions, etc. regarding these
presentations.

Definition Slide

Definition
Slides
Motivation
= a need or desire that energizes and directs
behavior.
Instinct
= a complex behavior that is rigidly
patterned throughout a species and is
unlearned.
Drive-reduction Theory
= the idea that a physiological need creates
an aroused tension state (a drive) that
motivates an organism to satisfy the need.
Homeostasis
= a tendency to maintain a balanced or
constant internal state; the regulation of
any aspect of body chemistry, such as
blood glucose, around a particular level.
Incentive
= a positive or negative environment
stimulus that motivates behavior
Hierarchy of Needs
= Maslow’s pyramid of human needs,
beginning at the base with physiological
needs that must first be satisfied before
higher-level safety needs and then
psychological needs become active.
Glucose
= the form of sugar that circulates in the
blood and provides the major source of
energy for body tissues. When its level is
low, we feel hunger.
Set Point
= the point at which an individual’s “weight
thermostat” is supposedly set. When the
body falls below this weight, an increase in
hunger and a lowered metabolic rate may
act to restore the lost weight.
Basal Metabolic Rate
= the body’s resting rate of energy
expenditure.
Anorexia Nervosa
= an eating disorder in which a person
(usually an adolescent female) diets and
becomes significantly (15 percent or more)
underweight, yet, still feeling fat, continues
to starve.
Bulimia Nervosa
= an eating disorder characterized by
episodes of overeating, usually highcalorie foods, followed by vomiting,
laxative use, fasting, or excessive
exercise.
Binge-eating Disorder
= significant binge-eating episodes, followed
by distress, disgust, or guilt, but without
the compensatory purging, fasting, or
excessive exercise that marks bulimia
nervosa.
Sexual Response Cycle
= the four stages of sexual responding
described by Masters and Johnson –
excitement, plateau, orgasm, and
resolution.
Refractory Period
= a resting period after orgasm, during which
a man cannot achieve another orgasm.
Estrogens
= sex hormones, such as estradiol, secreted
in greater amount by females than males
and contributing to female sex
characteristics. In nonhuman female
mammals, estrogen levels peak during
ovulation, promoting sexual receptivity.
Testosterone
= the most important of the male sex
hormones. Both males and females have
it, but the additional testosterone in males
stimulates the growth of the male sex
organs in the fetus and the development of
the male sex characteristics during
puberty.
Sexual Orientation
= an enduring sexual attraction toward
members of either one’s own sex
(homosexual orientation) or the other sex
(heterosexual orientation).
