Developmental Psychology Tools
Browse all available developmental psychology tools.
Available tools
- Age Equivalent Reference Offset Tool Compare supplied research age coordinates; no norm table, developmental age or diagnosis is generated.
- Attachment Research Episode Duration Term Tool Research observation duration accounting without attachment classification or a protocol-specific episode rule.
- Caregiver Report Disagreement One Item Tool Descriptive disagreement for one shared rating scale; no interpretation of child behavior or caregiver accuracy.
- Caregiver Report Role Label Label explicit caregiver-report respondent and role fields without inferring a family relationship or legal authority.
- Caregiver Response Mode Gap Tool Compare explicit response-mode labels across matched research items without scoring development.
- Caregiver Response Observation Date Gap Tool Measure signed calendar days between supplied child-study observation and caregiver-response dates without interpreting recall accuracy.
- Child Age Testing Date Offset Count chronological Gregorian calendar days from an explicit birth date to a testing date without applying age corrections or developmental norms.
- Child Choice Counterbalance Start Tool Deterministic research-condition cycling from an explicit start, not randomized treatment assignment.
- Child Executive Task Rule Switch Gap Tool Calculate child executive task rule switch gap from explicit caller-supplied inputs.
- Child Memory Delay Retention Fraction Tool Calculate child memory delay retention fraction from explicit caller-supplied inputs.
- Child Observation Setting Tag Attach an explicit setting and source to an observation record without interpreting behavior or environment.
- Child Report Parent Report Source Pair Tool Preserve explicitly supplied child and parent item responses as separate sources without adjudicating agreement.
- Child Report Proxy Role Conflict Tool Audit inconsistent supplied reporter-role metadata, without rating report validity or a child.
- Child Research Withdrawal Censor Time Tool Follow-up duration under caller-identified withdrawal, without interpreting consent or retention obligations.
- Child Study Age Rounding Disclosure Tool Preserve an explicit child-study age transcription and supplied rounding convention without inferring birth dates or development.
- Child Study Instruction Repeat Count Tool Calculate child study instruction repeat count from explicit caller-supplied inputs.
- Child Study Toy Familiarity Pair Tool Calculate child study toy familiarity pair from explicit caller-supplied inputs.
- Child Task Break Duration Compare a recorded child-task break interval with an explicit plan without prescribing a break duration.
- Child Task Look Validity Share Tool Audit caller-classified research looking-time validity without developmental interpretation.
- Child Task Valid Trial Proportion Tool Calculate child task valid trial proportion from explicit caller-supplied inputs.
- Child Vocabulary Checklist Unknown Denominator Tool Explicit item-status denominator policy, without an age-equivalent score or instrument norm lookup.
- Development Rating Scale Direction Crosswalk Tool Direction harmonization on a shared numeric range, without linking different instruments or estimating comparability.
- Developmental Assessment Adaptation Flag Compare explicit assessment-version identifiers and a recorded adaptation flag without determining score comparability.
- Developmental Item Nonresponse Code Encode explicit item presentation, response and decline states without converting nonresponse into a developmental score.
- Developmental Observation Coder Presence Flag Tool Flag a supplied recorded developmental observation without an explicit coder-presence flag.
- Developmental Observation Context Pair Tool Calculate developmental observation context pair from explicit caller-supplied inputs.
- Developmental Study Corrected Age Anchor Tool Research age arithmetic using an explicit full-term anchor; negative corrected ages are retained, with no developmental diagnosis or clinical rule.
- Developmental Task Demonstration Count Tool Count explicit demonstration flags in a supplied developmental-task event list without judging learning.
- Developmental Trajectory One Wave Change Tool Descriptive within-person score change per elapsed month; does not supply age norms or a developmental trajectory model.
- Developmental Trial Break Slack Tool Compare a research schedule with an explicit break allowance.
- Imitation Task Demonstration Delay Term Tool Calculate imitation task demonstration delay term from explicit caller-supplied inputs.
- Infancy Age Anchor Correction Gap Tool Compare supplied research age anchors; does not choose a clinical age correction.
- Infant Habituation Trial Block Tag Tool Preserve an explicitly assigned infant-study trial block without classifying behavioral habituation.
- Infant Looking Recovery Baseline Term Tool Looking-time recovery relative to an explicit observed habituation drop; values over one indicate overshoot.
- Joint Attention Initiation Response Lag Tool Caller-coded event timing and an explicit research response window; no attention state is inferred.
- Longitudinal Child Pseudonym Version Label Tool Associate an explicit longitudinal-study pseudonym with its supplied version without asserting deidentification.
- Longitudinal Study Age Wave Offset Tool Calculate longitudinal study age wave offset from explicit caller-supplied inputs.
- Longitudinal Visit Practice Count Count explicitly recorded prior testing and practice exposures while keeping visit ordinal distinct from practice exposure.
- Parent Child Turn Taking One Interval Tool Signed gaps preserve overlapping turns; caller event coding is accepted without conversational or clinical interpretation.
- Parent Teacher Rating Difference Compare explicitly supplied parent and teacher ratings on a shared scale without diagnosing a child or adjudicating either report.
- Participant Age Correction Offset Tool Apply an explicit research age correction without deriving clinical corrected age or developmental expectations.
- Research Play Turn Taking Transition Tool Record one explicit speaker transition in research play without inferring social or developmental ability.
- School Entry Cutoff Date Distance Tool Calculate signed date-only birth-minus-cutoff calendar days without determining school-entry eligibility.
- Sibling Household Cluster Label Namespace explicit participant and household-cluster codes without inferring biological sibling relationships.
- Symbolic Play Code One Transition Tool Count one directed transition in explicit sequential play codes, excluding the final code from predecessor opportunities.
- Task Familiarization Time Credit Tool Calculate task familiarization time credit from explicit caller-supplied inputs.
- Task Reward Choice Symbol Match Tool Compare exact supplied task-choice and reward symbol text without scoring developmental performance.
- Trial Attention Support Share Tool Calculate trial attention support share from explicit caller-supplied inputs.
- Trial Looking Time Share Tool One pre-coded target-region trial duration over valid visible time with excluded overlap preserved; no preference inference.
