The earliest systematic description is given in Mahaniddesa:
Jānāti bhagavā– “ayaṃ puggalo rāgacarito, ayaṃ dosacarito, ayaṃ mohacarito, ayaṃ vitakkacarito, ayaṃ saddhācarito, ayaṃ ñāṇacarito”ti. Rāgacaritassa bhagavā puggalassa asubhakathaṃ katheti; dosacaritassa bhagavā puggalassa mettābhāvanaṃ ācikkhati; mohacaritassa bhagavā puggalassa uddese paripucchāya kālena dhammassavane kālena dhammasākacchāya garusaṃvāse niveseti; vitakkacaritassa bhagavā puggalassa ānāpānassatiṃ ācikkhati; saddhācaritassa bhagavā puggalassa pasādanīyaṃ nimittaṃ ācikkhati buddhasubodhiṃ dhammasudhammataṃ saṅghasuppaṭipattiṃ sīlāni ca attano; ñāṇacaritassa bhagavā puggalassa ācikkhati vipassanānimittaṃ aniccākāraṃ dukkhākāraṃ anattākāraṃ.
As Ven. Dhammanando explained:
Some further notes on this subject, in part from untranslated material.
First a summary of the recommendations on how the six caritas ought to be instructed according to two pre-Visuddhimagga Texts. The sources are the Mahāniddesa (Nidd. ii. 359-60), a text from the Khuddaka Nikāya; and the Nettipakaraṇa (Netti. 24-5), an early paracanonical treatise on hermeneutics. The latter mentions only the first three temperaments (though the closely related Peṭakopadesa mentions all six, but not in connection with prescribing meditation subjects). Of particular interest is the deluded type, who is not given any meditation subject.Greedy temperament:
Mahāniddesa: "The Blessed one speaks to him with talk on unattractiveness (asubha-kathā)."
Nettipakaraṇa: "The Blessed One teaches him unattractiveness."Hating temperament:
Mahāniddesa: "The Blessed One makes known to him the development of lovingkindness (mettābhāvanā)."
Nettipakaraṇa: "The Blessed One teaches him loving-kindness."Deluded temperament:
Mahāniddesa: "The Blessed One requires him to engage in detailed questioning about expositions [of Dhamma] given in brief, timely hearing of the Dhamma and timely discussion of the Dhamma, and to reside with a teacher."
Nettipakaraṇa: "The Blessed One teaches him dependent arising (paṭiccasamuppāda)."Faithful temperament:
Mahāniddesa: "The Blessed One makes known to him an object worthy of faith (pasādanīya nimitta), namely, the well-awakenedness of the Buddha, the well-foundedness of the Dhamma, the well-practisedness of the Saṅgha, and his own [observance of] the precepts (sīlāni).Intelligent temperament:
Mahāniddesa: "The Blessed One makes known to him the insight sign (vipassanā nimitta), namely the aspects (ākāra) of anicca, dukkha and anattā."Speculative/distracted temperament:
Mahāniddesa: "The Blessed One instructs him in mindfulness of the in- and out-breath.
Secondly, the Commentary to the Mahāniddesa advises that a certain discourse from the Suttanipāta be taught to each temperament; here I give them with their titles in K.R. Norman's translation:
