Evolutionary Perspectives on Attraction
The "Averageness" Paradox
Which face do people generally find more attractive?
"Evolution favors the middle of the bell curve—it suggests a lack of harmful genetic mutations."
[Visual: Composite Face Comparison Diagram]
Symmetry = Health
Developmental Stability
Symmetry suggests the body handled stressors (illness, toxins) well during growth.
Genetic Quality
High symmetry acts as an "honest signal" of reproductive fitness and robust genes.
Perceptual Bias
Our brains process symmetric information faster, which we perceive as "pleasing."
Honest Signals of Fitness
Female Markers
Waist-to-Hip Ratio (approx. 0.7)
Clear skin and lustrous hair
Youthfulness (neotenous features)
Male Markers
Strong jawline (testosterone signal)
V-shaped torso (Shoulder-to-waist)
Height and resource indicators
"Evolution isn't Destiny."
Why might evolutionary psychology be limited in explaining why you like someone today?
Culture
Beauty standards shift across centuries and continents.
Individual
Personal experience and shared values often override "instinct."

Analyzing the Evolutionary Roots of Beauty
Student:
Period:
Task 1: The First Impression
In the "Composite Faces" activity, you viewed multiple images. Some were distinct individuals, while others were mathematical averages of 8, 16, or 32 faces.
1. Which face did you find most attractive? Describe its specific features (symmetry, skin clarity, features).
2. Why might our brains be wired to find "average" (mathematically symmetric) faces more appealing than unique ones? Link your answer to the concept of "developmental stability."
Task 2: Decoding Fitness Signals
Biological Marker
Waist-to-Hip Ratio (0.7)
Strong Jawline & Brow
Clear Skin / Glossy Hair
Instructions: Evolutionary psychologists argue these markers are "honest signals." For each marker, explain what biological advantage it supposedly signals to a potential mate.
3. "The Evolution of Cravings": Just as we crave high-sugar foods because they were once rare and vital, why might we crave "beautiful" features even if they aren't necessary for survival in 2026?
Task 3: Challenging the Theory
Consider the following scenario:
"A person finds themselves deeply attracted to someone who does not fit 'standard' evolutionary beauty markers—perhaps they have asymmetric features or do not possess the typical 'V-shaped' physique. However, they share a deep sense of humor and identical life goals."
Based on the scenario above, identify two limitations of using only Evolutionary Psychology to explain human attraction.

The Symmetry Hook
Show students a series of faces. Use the "Composite Faces" tool (readily available online or pre-set in slides). Have students vote on which is more attractive. Reveal that the "preferred" face is usually the mathematical average of 32 faces.
Key Question: Why do we like "boring" averages over "unique" beauty?

Biology & Signals
Lecture segment on reproductive fitness. Focus on honest signals :
WH Ratio (0.7): Signals fertility and lower risk of cardiovascular disease/diabetes.
Masculine Jaw: Signals high testosterone, which suppresses the immune system; only "healthy" males can survive high levels.

Key Concepts to Look For
Developmental Stability: The ability of an organism to withstand environmental/genetic stressors during development.
Sexual Dimorphism: Differences in physical characteristics between males and females beyond reproductive organs.
Common Misconceptions
"Evolution says we MUST like these things." (Correction: Evolutionary drives are tendencies , not laws).
"Biological standards are the same everywhere." (Correction: Cultural standards—like weight—vary drastically).
Closing Thought / Debrief
Remind students that while evolutionary biology explains the why of ancient instincts, psychology explains the how of modern connection. Next lesson: Proximity and the Power of Being Near.
Nearness Power Slides Power of Proximity
Environmental Factors in Attraction
The Propinquity Effect
"The more we see and interact with people, the more likely they are to become our friends."
Functional Distance
It's not just linear feet; it's about architectural design and paths that cross.
Festinger's Westgate Study (1950)
Mere Exposure Effect
Zajonc (1968)
Repeated exposure to a stimulus increases our liking for it.
Familiarity = Safety
Our ancestors associated the "familiar" with safety and the "novel" with danger.
The Algorithm
Social media uses this! Seeing a face in your feed repeatedly makes you like them more.
The Caveat
The Limit of Exposure
If your initial reaction to someone is negative, repeated exposure can actually increase your dislike.
Discussion: Can you think of a "frenemy" who fits this?
Virtual Proximity
In 2026, is physical distance still the #1 predictor of friendship?

Testing the Propinquity Effect & Familiarity
Researcher:
Date:
Phase 1: Mere Exposure Hook
During the rapid-fire image recognition challenge, you saw 20 abstract symbols. Some were shown 5 times, some 1 time, and some never.
1. Ranking Familiarity:
Which set of symbols felt most "pleasant" or "safe" to you? Why?
2. The "Safety" Hypothesis:
Explain why our evolutionary ancestors might have developed a preference for things they had seen before.
Phase 2: The Westgate West Dorm Study
In 1950, Festinger, Schachter, and Back studied friendship formation in a married-student housing complex.
Data Point A
People living next door to each other were 4x more likely to be friends than those at opposite ends of the hall.
Data Point B
Residents near stairwells or mailboxes had more friends on different floors than those in middle units.
Core Term
Functional Distance:
The probability that your paths will cross due to physical layout.
3. Architectural Analysis:
Think about your own school. Identify one "stairwell" or "mailbox" equivalent area where people from different social groups are forced to interact. Does this lead to liking or friction? Explain.
4. Digital Functional Distance:
How does a social media algorithm act as a "stairwell"? Consider "Mutual Friends" suggestions or the "For You" page.
Conclusion: Fate or Floorplan?
If proximity is so powerful, does that mean our friendships are just "accidents of geography"?

UNIT 2.2
Lesson Goal
Move students from biological instincts (Lesson 1) to environmental sociology. They will realize that attraction isn't just about "who" someone is, but "where" they are located in relation to us.
The "Symbol Experiment" Setup
To run the hook correctly: Prepare a slide with 10-15 obscure symbols (Chinese characters, Wingdings, or custom shapes). Show them at 0.5-second intervals. Ensure some symbols appear multiple times (5-7x) and others only once. Then, show them all at once and ask: "Which one do you find most aesthetically pleasing?"
Key Terms
Propinquity Effect
Functional Distance
Mere Exposure
Algorithmic Familiarity
Facilitation Notes
The "Westgate" Reveal
Explain that the people living near the mailboxes and bottom of the stairs were the "social hubs." They didn't have better personalities; they just had more "functional distance" crossing with others.
Ask: Who are the "mailbox" people in our school? (e.g., the student with a locker near the cafeteria entrance).
The Algorithm Connection
Connect this to Instagram/TikTok. When you "like" someone's photo once, the algorithm shows them more often. This increases your exposure, which unconsciously increases your liking.
Debate: Is this manipulation or just helping "destiny" along?
Cheat Sheet: Common Hurdles
Issue: Boring Hook
If students don't show a preference in the symbol test, it's often because the exposure wasn't distinct enough. Try showing the "preferred" symbol for 2 full seconds versus the others for 0.1 seconds.
Issue: Contradiction
Students will bring up "long-distance relationships." Acknowledge that while proximity predicts formation , it doesn't necessarily dictate maintenance .
Fact Check
The Westgate study found that people were twice as likely to become friends with someone living two doors away than someone living four doors away.
Zajonc's research works even with stimuli shown subliminally (too fast to consciously see).

Distribution: Every student gets one card. DO NOT LOOK AT THE NUMBER. The Forehead: Hold the card facing outward on your forehead. You can see everyone else's number, but not your own.Market Play: Walk around the room. Attempt to form a "partnership" with another student.The Rules:
You want to partner with the highest number you can find.
You can say "Yes" or "No" to a partnership request.
If you are a '2' and approach a '10', they will likely say no. If you are a '9', they might say yes.
Social Signals: You must deduce your own "value" based on how others react to you. Are they rushing toward you? Or avoiding eye contact?

A. At what point did you realize your "number"? What specific social signals gave it away?
B. If you were a "low number" (1-4), how did your strategy change after being rejected by "high numbers"? If you were a "high number," how did it feel to be the center of attention?
C. How does this simulation support the Matching Hypothesis? (Use the term "social desirability" in your answer).

Attachment Styles in Adult Love
The Internal Working Model
How our primary caregivers treated us as infants creates a "blueprint" for all future relationships.
Ainsworth & Bowlby
Attachment isn't just for babies—it's the foundation of adult intimacy.
Two Key Questions:
Secure Attachment
"I find it relatively easy to get close to others and am comfortable depending on them."
Dynamics:
• High trust, low anxiety
• Comfortable with intimacy
• Not worried about being abandoned
Adult Outcome:
"Able to communicate needs directly and support partner's independence."
The Insecure Spectrum
Anxious-Preoccupied
Fears rejection. Desperately seeks closeness, often "clinging" or demanding reassurance.
"I often worry that my partner doesn't really love me or won't want to stay with me."
Dismissive-Avoidant
Values independence over intimacy. Pulls away when things get too "serious" or emotional.
"I am somewhat uncomfortable being close to others; I prefer not to depend on them."
Diagnostic Lab
"Alex hasn't texted back in 4 hours. How do the different attachment styles react?"
A: "They're probably just busy. I'll see them tonight."
B: "They're ignoring me. Did I say something wrong?"
C: "I don't care. I have my own things to do anyway."

Clinician:
Secure
Comfortable with intimacy and independence; trusts partner.
Anxious
Fear of abandonment; seeks constant reassurance and closeness.
Avoidant
Suppresses emotions; distances self when closeness increases.
Case Study #1: Jordan & Taylor
Jordan and Taylor have been dating for six months. Whenever Taylor goes out with friends, Jordan sends 10+ texts asking when Taylor will be home. If Taylor doesn't reply immediately, Jordan starts to worry that Taylor is losing interest. Jordan often says, "I just love you so much I can't stand to be away from you."
Diagnosis:
Primary Fear:
Prediction: How will Taylor react if Taylor has a Secure attachment style?
Case Study #2: Casey & Sam
Sam just received a big promotion at work and wants to move in together to celebrate. Casey, who has been dating Sam for two years, feels "suffocated" by the suggestion. Casey tells Sam, "I need my own space, and things are fine the way they are." Casey starts spending more time at the gym and stops answering Sam's calls as frequently.
Diagnosis:
Primary Defense Mechanism:
Analysis: Why might Casey view intimacy as a threat to independence?
Part 2: The Stress Response
Psychologists argue that attachment styles are most visible during stress or conflict . When you are upset with a friend or partner, how do you typically respond? Select the profile that best fits your "default" blueprint.
A
The Communicator
"I tell them I'm upset, listen to their side, and try to find a solution together."
B
The Reassurer
"I worry they are mad at me, so I apologize a lot or keep checking in to see if we're okay."
C
The Runner
"I shut down, stop talking, or leave the room. I'd rather deal with it on my own."
Final Thought: "Earned Security"
Can someone change their attachment style? Research on Earned Security suggests that through healthy relationships and self-awareness, insecure adults can become secure over time.
What is one "habit" an Anxious person could learn from a Secure person to improve their relationships?

• Pattern Recognition
Facilitation Notes
01
The Diary Entry Hook
Read the three "Texting" reactions from the slides aloud. Have students stand in a corner of the room (A, B, or C) corresponding to which reaction they think is most "toxic" or "healthy." This gets them moving and debating the definitions of healthy boundaries.
02
Internal Working Models
Explain the Working Model as a self-fulfilling prophecy.
Anxious Example: "I think you'll leave, so I cling to you, which makes you feel smothered, so you leave... which proves I was right."
Avoidant Example: "I think people are unreliable, so I don't share my feelings. The relationship stays shallow, so people leave... which proves I shouldn't rely on them."
Worksheet Key & Insights
Case #1: Jordan (Anxious)
Diagnosis: Anxious-Preoccupied.
Fear: Abandonment / Unworthiness.
Secure Reaction: Taylor would validate Jordan's feelings but maintain healthy boundaries (e.g., "I'm having fun, I'll call you when I'm home").
Case #2: Casey (Avoidant)
Diagnosis: Dismissive-Avoidant.
Defense: Distancing / Deactivating.
Analysis: Intimacy feels like a loss of control or a trap. By pulling away, they restore their sense of "safe" independence.
Teacher Tip: Moving to Security
Ensure students know attachment isn't a life sentence. A key strategy for an Anxious person is learning to self-soothe rather than looking to a partner for all validation. For an Avoidant person, it's gradual vulnerability .
