					         Gut Feelings in the Desert:
 Antoine De St. Exupery and the Dragon Fly
I shaved carefully in a cracked mirror. From time to time I
went to the door and looked at the naked sand. … I was
thoughtful. … For the moment everything was all right. But
I heard something sizzling. It was a dragonfly knocking
against the lamp. Why it was I cannot say, but I felt a
twinge in my heart.
I went outdoors and looked round. The air was pure. …
Over the desert reigned a vast silence as of a house in
order. But here were a green butterfly and two dragonflies
knocking against my lamp. Again I felt a dull ache which
might as easily have been joy as fear, but came up from the
depths of me.
     St. Exupery in the Desert, continued
Something was calling to me from a great distance. Was it
Once again I went out. The wind had died down
completely. The air was still cool. But I had received a
warning. I guessed, I believed I could guess, what I was
I climbed a dune and sat down face to the east. If I was
right, the thing would not be long in coming. What were
they after here, those dragonflies, hundreds of miles from
their oases inland?
            St. Exupery in the Desert

Wreckage thrown up upon the beach bears witness to a
storm at sea. Even so did these insects declare to me that
a sand storm was on the way, a storm out of the east that
had blown them out of their oases.
Solemnly, for it was fraught with danger, the east wind
rose. … But that was not what excited. What filled me
with a barbaric joy was …that I had been able to read the
anger of the desert in the beating wings of a dragonfly.

            St. Exupery, A. (1939). Wind, sand, and stars.
I. I’m about to fly across the Sahara, I’ve done it a 100 times, but
something is bugging me. What?

2. Those insects bumping against my lamp are bothering me.
How come?

3. Wait a second! I'm in the middle of the barren Sahara; what
are a moth and a dragonfly doing out here?

4. What would it take to transport insects hundreds of miles from
their native environment? Now put this into a succinct problem

5. Does the presence of insects in the remote barren desert
indicate the advent of a windstorm?

“The arrival of live insects within the desert interior is a
precursor of high winds.”

What does St. Exupery do to test this hypothesis?
                 FORMS OF HYPOTHESES
                                  "A" = Bugs
                                  "B" = Sandstorms
                                  "C" = Location aridness
                                  "D" = Windy season

I. A       B      Bugs are related to sandstorms
I. A  B          Bugs predict sandstorms
II. (A X B)  C: Bugs & location aridness predict sandstorms

III. AB if D:    Bugs predict sandstorms IF windy season has started

Example of Theory:

Time Perspective (Zimbardo & Boyd, 1999):

People systematically differ in how they subjectively order
time into past, present, and future.

In other words, people can be characterized as
“present oriented”, or “future oriented”.
  Hypotheses that Derive from Time Perspective Theory

People differ in time perspectives, and this shapes their

General Hypothesis
Future Oriented (FO) people are better
at meeting time demands than are (PO).

Experimental Hypotheses

FO will sign up for experiments sooner than PO.

                 Null Hypotheses

Defined:    Null hyp. states that there is no relation
            between variables.

Examples:     Class size is not related to performance
              The sexes do not differ in aggression.
              Bugs don’t predict sandstorms
Proper and Improper Use of Null Hypothesis
Proper use of null hypothesis:
       As a contrast, foil, to hyp. we want to confirm
               H1: Smaller classes  improved performance
               Ho: Smaller classes unrelated to performance

Improper use of null hyp: As the object of research
              H1: Smaller classes are unrelated to performance
Problems in trying to confirm null hyp:
       1. Confirmation could be due to actual absence of effect
       2. Confirmation could occur b/c study improperly done.

    1. Multivariable: More than one causal variable but only one
    outcome variable:

        EXAMPLE: School climate (leadership, teacher morale,
        level of violence) affects student’s test scores.

    2. Multivariate: More than one causal variable and more
    than one outcome variable.

        EXAMPLE: School climate (leadership, teacher morale, level
             of violence) affects students’ school performance
        scores, discipline, attendance).
    Univariate vs. Multivariable Research

Univariate Research: One predictor variable and one
outcome variable. Univariate is better designed to ask
questions about whether certain things occur.

Example: Does race of writer (Black vs. White) affect quality
of feedback? (i.e., Is there a feedback bias?)

Multivariable Research: Two or more predictor variables and
one outcome variable. Multivariable research permits
investigation into underlying causes.

Example: Does race of writer (Black vs. White) affect quality
of feedback, due to degree of social risk (high vs. low)?
(i.e., is there a racial bias, and is it caused by perceived risk?)

   Which conditions do you find satisfactory? Why?
Concept: An abstraction formed by generalizing from particulars.
     Examples: Attention, Emotion, Learning, Prejudice
Construct: A concept that:
1. Allows for objective observation.
     * Can be measured (i.e., pounds, years, tears)
     * Can be described in terms of explicit, replicable operations
        (place subject on scale, gather birth date from drivers’ license, OR
     * Built on other constructs that are themselves based on operations.
2. Relates theoretically to other constructs
  * Built upon other constructs: (empathy = perspective taking + imagination)
  * A building block for other constructs: (empathy  emotional intelligence)
3. Defined distinctly [Kent’s add-on]
    * “Trust = “believe w/o questioning” = gullibility = dependency = trust?

Intriguing, fascinating, provocative question: Is “hope” a concept or construct?

Prejudice                     =   Concept

Hostility toward minorities   =   Construct

Physical distance

Concepts that have a range of values, such that X > 1
       “Heaven” has no range, not a variable
       “Church attendance” has a range, is a variable
Observable and measurable
       “Love” is not observable
       “Eye gazing” is observable
Form building blocks of constructs
       “Size” is construct
       “Inches” is variable
   Qualitative and Quantitative Variables

       Dichotomous, polychotomous
       All numeric values of equal normative value

Examples       Gender, race, blind vs. don’t blind Ghack boy

       Continuous—take on a range of values
       Numeric values represent more/less of attribute

Examples       No. pos. feedback comments, feedback ratings
Steps, or “operations” taken to measure or create a variable.

Measured: Variable defined in terms of how it is measured

  Francois: “Height, she is ze number of centimeters.”

  Frank: “Height is the number of inches, by crackie!”

Experimental: Expt’l steps taken to create variable
  Confed. temperament = eye contact, voice tone, smiles/stares

What are operationalizations for “stress”, for “aggression”?
           Value of Operationalization?

1. Enforces mental rigor; forces evaluation of assumptions.

2. Provides uniformly understood meanings

3. Helps to resolve discrepancies in science.

    Lending a Hand: Social Regulation of the Neural
                 Response to Threat
[Coan, J., Schaefer, H., & Davidson, R., (2006) Psych. Science, 17, 1032-1039]

 ...For this fMRI study, 16 married women were subjected
 to the threat of electric shock while holding their
 husband’s hand, the hand of an anonymous male
 experimenter, or no hand at all. Results indicated an
 attenuation of activation [in systems regulating threat]
 when women held their husband’s hand. Most strikingly,
 the effects of spousal hand-holding on neural threat varied
 as a function of marital quality ... .

              Quality of essay

Attributive (measured): Variables that cannot be

                Latent Variables
Latent variables are variables that cannot be directly

Latent variables are “emergent” – they arise from the
  joint association of more particular, measurable

Latent variables are sometimes referred to as “factors”

Factor analysis is method used to discover and confirm
  latent variables.
