Final review

Three theories, and one moderator

There are two questions here and they are usually merged. The first names three theories — social exchange, equity and social penetration — and asks how relationships are maintained or ended. The second asks what attachment style does to intimacy. The strong post keeps them apart and then connects them deliberately, because attachment is not a fourth theory of maintenance sitting alongside the other three. It is the individual-differences variable that changes how the other three operate for a given person. Treat it as a moderator and the post has an argument; treat it as another bullet and you have four summaries. Say that explicitly in your opening line. A post that announces attachment will be used to explain why the same exchange calculation produces different decisions in different people has told the reader what the argument is before making it.

The three theories are not three ways of saying the same thing, and the marks are in where they diverge. Social exchange evaluates a relationship against what you expect and what else is available. Equity says the ratio of contributions to rewards has to feel proportional — and it predicts distress for the person receiving too much as well as too little, which is the part most posts omit. Social penetration is not an evaluative theory at all; it describes a process, in which intimacy grows through the breadth and depth of self-disclosure, and dissolves through depenetration as disclosure narrows back down. One theory is about accounting, one about fairness, one about a trajectory. Keep the distinction visible in your verbs, too: exchange theory has people comparing, equity theory has them balancing, and social penetration has them disclosing. Three different actions, and only the third describes something that happens gradually and can be observed from outside.

Theory	What maintains the relationship	What ends it
Social exchange	Rewards exceed costs, and outcomes compare well against what you have come to expect	A better available alternative, or outcomes falling below your comparison level — the decision is comparative rather than absolute
Equity	The ratio of contributions to benefits feels proportional to both people	Sustained imbalance producing distress. Resentment when under-benefited, guilt when over-benefited, and pressure to restore balance or exit
Social penetration	Reciprocated self-disclosure that expands in breadth and deepens over time	Depenetration — disclosure narrows and withdraws when its costs come to outweigh its rewards, and the relationship de-escalates in reverse

Now the detail that will separate your post from the rest, and it is hiding in the word "or". The prompt asks about friendships or intimate relationships, and equity does not behave identically across the two. In spousal relationships, under-benefiting and over-benefiting are about equally distressing, which is what equity theory predicts. In friendships, under-benefiting is substantially more distressing than over-benefiting — those who under-benefit report greater stress, depression and anxiety. The proposed explanation is voluntariness: a dissatisfied friend can simply leave, so receiving more than you give carries less weight where exit is cheap.

That gives you a real argument rather than a summary. The three theories are not equally powerful in every relationship type, and the differences track how easily the relationship can be exited. Social exchange's comparison level for alternatives does the most work where alternatives are plentiful and leaving is low-cost, which describes friendship better than marriage. Equity's symmetric prediction holds best in bonds that are harder to leave. Saying which theory you would expect to explain most in which context is the kind of claim a discussion post can actually be graded on, and it is available from the evidence rather than from opinion. It is also a defensible position rather than a safe one, which is what a discussion post is for — a classmate can disagree with you about which theory dominates in friendship, and that disagreement is exactly the kind the participation policy is asking for.

Then bring attachment in as the moderator. Attachment anxiety and attachment avoidance are two dimensions rather than a set of boxes, and each one changes the inputs the other theories take. Highly anxious people are heavily invested and yearn for closeness while holding negative self-views, staying vigilant for signs a partner is withdrawing, and using hyperactivating strategies that sustain and escalate their concerns — sometimes smothering the partner they are trying to hold. Highly avoidant people seek less comfort and support when distressed, use deactivating strategies to protect independence and autonomy, and disengage behaviourally, emotionally and cognitively under stress. Note that both patterns produce distance in the end, by opposite routes: one by pursuing closeness until the other person retreats, the other by declining closeness before it can be lost. The dimensional framing matters practically as well: because anxiety and avoidance vary independently, someone can score high on both, and that combination behaves differently from either alone rather than averaging out into security.

Translate that into the language of the other three theories and the post becomes integrated rather than sequential. In social penetration terms, avoidance suppresses depth and slows reciprocity, while anxiety can push disclosure faster than the other person is matching — a violation of reciprocity in the opposite direction. In exchange terms, attachment shifts the comparison level itself: what counts as an acceptable outcome differs by working model. In equity terms, an anxious partner may tolerate substantial under-benefit rather than risk the relationship, which is why the theory's prediction of exit does not always materialise. Each of those is a sentence you can write that no summary of attachment theory on its own would produce, and that is the difference between integrating the material and reporting it. Pick one of the three translations and develop it properly rather than gesturing at all three, since a discussion post has room for one worked connection and not for a taxonomy of them.

One caution and one useful nuance to close. The caution: attachment style is a pattern, not a diagnosis, and the sources report tendencies with real variance rather than types that determine outcomes. The nuance worth including is that these effects are conditional — partner commitment substantially buffers the difficulties associated with anxiety, and avoidant individuals benefit more from instrumental support than emotional support, precisely because it does not impinge on the autonomy they are protecting. Both facts turn a description of attachment styles into something with implications for how relationships are actually maintained. Those conditions also make the post more useful than a taxonomy, because they identify what could change rather than only what someone is like. End on that if you can, because a post that says what would have to change reads as an analysis, while a post that says what people are like reads as a description of a personality test.

Likely learning objectives

Inferred from the brief — check these against your own rubric.

01
Distinguish three theories of relationship maintenance by what each actually explains.
02
State equity theory's prediction for over-benefited as well as under-benefited partners.
03
Recognise that theoretical predictions vary by relationship type and by ease of exit.
04
Treat attachment as a moderator of the other theories rather than as a fourth theory.
05
Describe attachment along the anxiety and avoidance dimensions rather than as fixed types.

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you. Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted. If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations. Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements. Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week. I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!

Turn the brief into deliverables

01
A description, using social exchange theory, of how relationships are maintained or ended.
02
The same using equity theory.
03
The same using social penetration theory.
04
A discussion of the role attachment style plays in the level of intimacy shared in friendships or intimate relationships.
05

Building an integrated post

Separate the two questions

Establish that the theories answer maintenance and dissolution, and attachment answers intimacy, before connecting them.

The three theories, differentiated

Give each theory its own mechanism for maintenance and for ending.

Where the predictions diverge

Use the friendship-versus-marriage equity evidence to show the theories are not equally powerful everywhere.

Attachment as a moderator

Describe anxiety and avoidance and their effects on closeness and disclosure.

Integration

Translate attachment effects into the vocabulary of exchange, equity and penetration.

Conditions and limits

Note buffering effects and the difference between instrumental and emotional support.

Searching dimensions, not labels

Search sequence

1.
Search attachment by its two dimensions — anxiety and avoidance — rather than by style labels, because the current literature is dimensional and the label-based sources tend to be older and more deterministic.
2.
Look for equity findings that compare relationship types, since the interesting result is the asymmetry between marriages and friendships rather than the theory's general statement.
3.
For social penetration, search 'depenetration' specifically. Searching the theory alone returns descriptions of deepening and leaves the dissolution half of the question unsourced.
4.
Prefer sources that report moderators and buffering effects, because conditional findings are what let you connect attachment to the other three theories rather than listing it after them.
5.
Check whether a finding came from married, cohabiting or friendship samples before generalising it, given that the prompt explicitly spans both friendships and intimate relationships.

01
Adult Attachment, Stress, and Romantic Relationships
Current Opinion in Psychology · 2017
The dimensional account of attachment the post needs, with the mechanisms rather than the labels. Highly anxious individuals intensely pursue reassurance and proximity, hold negative self-views, stay vigilant to signs a partner is pulling away, and use hyperactivating strategies that sustain or escalate their concerns — sometimes smothering the partner. Highly avoidant individuals seek less comfort and support when distressed, use distancing and deactivating strategies to promote independence and autonomy, and disengage behaviourally, emotionally and cognitively. Also the two conditional findings: partner commitment substantially buffers the anxious pattern, and avoidant people benefit from instrumental rather than emotional support.
02
The psychological costs of social support imbalance: Variation across relationship context and age
Journal of Health Psychology · 2017
The evidence that turns the prompt's 'friendships or intimate relationships' into an argument. In spousal relationships under-benefiting and over-benefiting are about equally distressing, as equity theory predicts. In friendships, those who under-benefit report greater stress, depression and anxiety than those who over-benefit, and the authors attribute the difference to voluntariness — a dissatisfied friend can dissolve the relationship, so excess receipt costs less where exit is cheap.
03
Social penetration theory
EBSCO Research Starters (Communication and Mass Media) · 2019
The process account and its reward-cost basis: breadth is what topics people will talk about and depth is how thoroughly those topics are explored, with intimacy growing as both expand. Altman and Taylor's claim that relationships succeed when disclosures are rewarding and fail when they prove costly, the progression from orientation through exploratory affective and affective to stable exchange, and depenetration as the stage where disclosure decreases once costs exceed benefits.
04
Relationships and Well-being
Noba Project · 2021
Covers what close relationships do for well-being and how intimacy is sustained, which gives you the outcome side of the attachment argument. Useful when you connect an attachment style to a relational consequence rather than describing the style alone.

Before you post

Common mistakes

Treating the three theories as three ways of saying rewards matter. Exchange is comparative accounting, equity is proportional fairness, and social penetration is a disclosure trajectory. Collapsing them means the 'or ended' half of the question gets one mechanism instead of three.
Omitting the over-benefited prediction. Equity theory's distinctive and counter-intuitive claim is that receiving more than you give is also distressing — guilt rather than resentment. A post that only discusses under-benefiting has described exchange theory again.
Treating attachment as a fourth theory of maintenance. It is an individual-differences variable that changes the inputs the other three take, and saying so is what makes the post integrated rather than sequential.
Using attachment categories as types. Anxiety and avoidance are dimensions with substantial variation, and the literature reports tendencies rather than determinants. 'Anxious people always...' overstates every source you could cite.
Ignoring the word 'or' in friendships or intimate relationships. Equity's symmetric prediction holds in marriages but not in friendships, where under-benefiting is considerably more distressing — and that difference is evidence you can use rather than a complication to avoid.
Describing social penetration only as deepening. Depenetration is the half that answers 'or ended', and it is a gradual narrowing of disclosure rather than a decision.
Presenting attachment effects as unconditional. Partner commitment buffers the difficulties associated with anxiety, and avoidant people benefit from instrumental rather than emotional support — the conditions are more interesting than the main effects.
