The purpose of this study is to determine the respective roles of aging and schizophrenia in the regulation of metamemory using a sentence construction strategy. 4 groups will be necessary to comparison: Adult patients (18-45 years) Adult controls (18-45 years) Aged patients (≥ 55 years) Aged controls (≥ 55 years) The effects of age and the disease could lead to interaction in regulating metamemory. The effect of age would be aggravated by the disease.
Metamemory measurement * Objective: Measurement of monitoring and control capabilities, and relations between these two abilities when learning of word pairs. * Description: The hardware consists of two lists of 30 pairs of French words, each pair of words being composed of a word index and a target word (names of concrete objects). Among the 60 word pairs, 30 are strongly associated items (or easy items, the other 30 being weakly associated or difficult items. In front of a computer screen, each participant is subjected to a first learning test in which 30 pairs of words appear one by one on the screen. Participants have the option to control the time of presentation of each pair of words. After a retention time of 4 minutes of information devoted to nonverbal distractive task, follows an evaluation phase of deferred judgments of learning (JOL time), where for each pair of words studied, the word index is presented without the target word. Participants must then assess a learning judgment for each pair of words, that is to say they have to estimate, on a 5-point scale, their ability to remember later the target word in the presentation the index word. This JOL (judgments of learning ) assessment phase is immediately followed by cued recall test. For the second learning test (30 other word pair), the steps are identical. Prior to this second learning, building instruction of a phrase with two words to learn is proposed. Participants are trained on 5 pairs of words. The study concludes with a question phase, during which participants give their impressions of the experience, describe the learning strategies they used and generally consider their ability mnemonic during daily tasks.

RECRUITINGdifference of judgement of learning using a 5 point scale (0%, 25%, 50%, 75%, 100%) in the sentence construction strategy
the 4 groups of participants formed by the case-control study in two age strata value their judgments of learning for each pair of words using a 5 point scale (0%, 25%, 50%, 75%, 100%) in the sentence construction strategy. Four groups are : * Adult schizophrenic patients (18-45 years) * Aged patients with schizophrenia (≥ 55 years) * Adults controls (18-45 years) * Aged controls (≥ 55 years)
Time frame: at day 1
difference of judgement of learning using a 5 point scale (0%, 25%, 50%, 75%, 100%) between sentence construction and reading strategies.
the 4 groups of participants formed by the case-control study in two age strata, value their judgments of learning for each pair of words using a 5 point scale (0%, 25%, 50%, 75%, 100%) in a sentence construction strategy and in a reading strategy. For each group, difference between these two strategies will be compared. Four groups are : * Adult schizophrenic patients (18-45 years) * Aged patients with schizophrenia (≥ 55 years) * Adults controls (18-45 years) * Aged controls (≥ 55 years)
