EFT, Embedded Figures Test;
Fr EFT, French EFT; CFT, Closure Flexibility Test; HFT, Hidden Figures Test; GEFT, Group Embedded Figures Test. DV = Dependent Variable (RT, reaction time; #F, number of failed items; #C, number of correct items). IQ test = type of intelligence test conducted (RSPM, Ravens Standard Progressive Matrices; QWT, Quick Word Test; SILS, Shipley Institute of Living Scale; WAIS, Weschler Adult Intelligence Scale; SBVS, Stanford-Binet Vocabulary Scale). Scale = scale used to measure symptoms (in patients) or schizotypy traits (SCI, Structured Clinical Interview; O-LIFE, Oxford-Liverpool Inventory of Feelings and Experiences; CS, Chapman Scale; SPQ, Schizotypal Personality Questionnaire; BPRS, Brief Psychiatric Rating Scale). N, number of participants; “%F”, percentage of females. EOS, Early Onset Schizophrenia; ASD, Autism Spectrum Disorder; MR, Mental Retardation. Neurpsychiatric patients were composed of: anxiety reaction (n = 10), depressive reaction (n = 9), manic-depressive reaction (n = 2), psychopathic reaction (n = 1), passive-aggressive reaction (n = 1) and emotionally unstable personality (n = 1).
