In order to verify this hypothesis, we collected a series of autobiographic texts written by a set of 202 participants. Additionally, a psychological instrument (Fr\u00edas questionnaire) was applied to these same participants to measure their attachment style. We identified characteristic patterns for each style of attachment by means of two approaches: (1) mapping words into a word space model composed of unigrams, bigrams and\/or trigrams on which different classifiers were trained (Na\u00efve Bayes (NB), Bernoulli NB, Multinomial NB, Multilayer Perceptrons); and (2) using a word-embedding based representation and a neural network architecture based on different units (LSTM, Gated Recurrent Units (GRU) and Bilateral GRUs). We obtained the best accuracy of 0.4079 for the first approach by using a Boolean Multinomial NB on unigrams, bigrams and trigrams altogether, and an accuracy of 0.4031 for the second approach using Bilateral GRUs.<\/jats:p>","DOI":"10.3233\/jifs-179883","type":"journal-article","created":{"date-parts":[[2020,6,12]],"date-time":"2020-06-12T12:39:45Z","timestamp":1591965585000},"page":"2189-2199","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Psychological attachment style prediction based on short biographies"],"prefix":"10.1177","volume":"39","author":[{"given":"Hiram","family":"Calvo","sequence":"first","affiliation":[{"name":"Centro de Investigaci\u00f3n en Computaci\u00f3n, Instituto Polit\u00e9cnico Nacional, J.D.
