What it does

Devpsych Theory And Hypotheses is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when stating the developmental theory and age-graded hypotheses for a Developmental Psychology (APA) manuscript. The journal rewards hypotheses that are explicitly about change (age effects, within-person trajectories, mechanisms) and a clean confirmatory/exploratory split under JARS. Structures the argument; it does not run analyses.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

When your agent uses it

  • Stating the developmental theory and age-graded hypotheses for a Developmental Psychology (APA) manuscript

Example prompts

  • “/devpsych-theory-and-hypotheses”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. State the mechanism of change. What developmental process (maturation, learning, transactional
  2. Specify the form of the developmental hypothesis. Be explicit about which of these you predict
  3. Derive directional predictions. Give a sign and, where possible, a magnitude/effect-size
  4. Mark hypothesis status. Separate confirmatory (preregistered, predicted) from exploratory
  5. State what would disconfirm the developmental account — e.g., a flat trajectory, a reversed age

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Devpsych Theory And Hypotheses loads about 1.5k tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 522 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~93
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when stating the developmental theory and age-graded hypotheses for a Developmental Psychology (APA) manuscript. The journal rewards hypotheses that are explicitly about change (age effects, within-person trajectories, mechanisms) and a clean confirmatory/exploratory split under JARS. Structures the argument; it does not run analyses.

Developmental Theory & Hypotheses (devpsych-theory-and-hypotheses)

Developmental Psychology rewards a theory of change and age-graded, directional hypotheses. Because the journal asks for a credible developmental claim and applies JARS reporting, the cardinal rule is: state the developmental mechanism and the predicted form of change before the data, and label exploratory analyses as exploratory.

When to trigger

  • Writing the theoretical framing and hypotheses
  • Preparing a preregistration / pre-analysis plan for a developmental study
  • Reconciling what you predicted about change with what the trajectories show
  • A reviewer flagged the work as "atheoretical," "not developmental," "post hoc," or "HARKed"

Build the developmental argument

  1. State the mechanism of change. What developmental process (maturation, learning, transactional parent–child dynamics, scaffolding, cumulative risk) predicts the effect, and why it changes with age.
  2. Specify the form of the developmental hypothesis. Be explicit about which of these you predict: an age main effect, an age × condition interaction, a growth-curve shape (slope sign, acceleration), a within-person change, or a moderated trajectory.
  3. Derive directional predictions. Give a sign and, where possible, a magnitude/effect-size expectation — not "age will be related to X."
  4. Mark hypothesis status. Separate confirmatory (preregistered, predicted) from exploratory (generated after seeing data) analyses, clearly, per JARS.
  5. State what would disconfirm the developmental account — e.g., a flat trajectory, a reversed age slope, or invariance failure that means the construct is not the same across ages.

Age-graded hypothesis forms (name yours)

Hypothesis formWhat it claimsTypical test
Age main effectlevel differs by ageage as predictor (cross-sectional or wave)
Age × conditionmanipulation effect differs by ageinteraction term
Growth shapewithin-person slope/curvaturelatent growth / multilevel
Sensitive periodeffect concentrated in an age windownonlinear / spline age terms
Transactionalchild→parent and parent→child over timecross-lagged / RI-CLPM

Worked micro-example — theory to hypothesis status (illustrative)

A longitudinal effortful-control package, written so the developmental claim and status are legible.

Mechanism: Sensitive, contingent parenting scaffolds the maturation of
           effortful control; the scaffolding payoff grows across early childhood.
H1 (confirmatory, preregistered): Effortful control shows positive
           within-person growth from age 4 to 8 (latent slope > 0).
H2 (confirmatory): Maternal scaffolding at wave 1 predicts a steeper slope
           (scaffolding × time interaction, directional).
H3 (exploratory): Bidirectional child→parent effects across waves
           (RI-CLPM) — labeled exploratory; preregister for a future sample.
Disconfirming: a flat/negative latent slope, or measurement non-invariance
           across ages (the construct is not the same thing being "grown").

Avoiding HARKing in developmental work

  • Do not present an unexpected age interaction or a trajectory shape you discovered post hoc as if it had been predicted. If you found it after seeing the data, say so and frame it for confirmation.
  • Constraints on generality matter here: name the ages, populations, and cohort/era to which the developmental claim is meant to apply, rather than implying it holds at every age and place.

Theory-stage reviewer pushback and the venue fix

Reviewer pushbackDevelopmental Psychology fix
"Atheoretical / mechanism unclear"state the developmental mechanism and why it changes with age in one or two sentences
"This is not developmental"recast the hypothesis as change (slope/interaction/within-person), not a single-age correlation
"Looks HARKed"show the preregistration; relabel post hoc trajectory shapes exploratory
"Claim outruns the design"scale H1 to what the ages/waves can support; add a constraints-on-generality clause

Anti-patterns

  • Hypotheses about a relationship "in children/older adults" with no change component
  • Non-directional "age will be associated with X" predictions
  • Blurring confirmatory and exploratory analyses (JARS expects the split)
  • Ignoring that an effect could be cohort, not age, and theorizing as if it were maturation
  • No statement of what trajectory or interaction would disconfirm the account

Output format

【Mechanism of change】the developmental process, briefly
【Developmental hypothesis form】age effect / age×condition / growth shape / within-person / moderated
【Hypotheses】directional, testable (H1, H2, …)
【Status】confirmatory (preregistered) vs exploratory
【Disconfirming evidence】trajectory/interaction/invariance result that counts against it
【Next】devpsych-literature-positioning
