Friday (2/7) the Undergraduate Study Program of the Faculty of Psychology UGM held a Research Knowledge Sharing event with the theme “Construct Validation of Learning Efficiency (GI) and Retrieval Fluency (Gr) of AJT COGTEST”. This event is a routine dissemination of research results from UGM students and lecturers.
The event took place from 13.30 WIB until 15.00. The participants of this event are lecturers and students and lecturers of the Faculty of Psychology UGM.
The speakers at this event were Wahyu Widhiarso, S.Psi., M.A., a lecturer at the Faculty of Psychology UGM, a researcher and also the Head of the Psychodiagnostic Tool Development Unit (UPAP) of the Faculty of Psychology UGM. On this occasion Wahyu explained the results of the thesis from A. Luthfia, an undergraduate student at the Faculty of Psychology, UGM who tested the construct validity of one aspect (broad ability) of the AJT test related to long-term memory, namely the effectiveness of information storage (learning efficiency) and retrieval of information stored in long-term memory (retrieval fluency).
Wahyu opened the presentation by explaining in general the CHC theory which is the basis for the development of the AJT cognitive test. CHC is an acronym for Cattell (Raymond Cattell), Horn (John L. Horn), and Carroll (John B. Carroll), the three scientists who developed the theory of cognitive abilities.
Specifically, Wahyu explained the operational definition and aspects of long-term memory, which was initially called Glr and then broken down into different broad abilities, namely Gl (long-term storage or learning efficiency) and Gr (long-term retrieval or retrieval fluency).
Learning efficiency or long-term storage (Gl) is the ability to learn new information efficiently. This allows information to enter long-term memory. Individuals who have this capacity are able to learn new information efficiently so that it enters and is stored in long-term memory.
Furthermore, the definition of retrieval fluency or long-term retrieval (Gr) is the ability to represent and reproduce information that has been stored. After doing some research, this ability has a very small correlation with the ability of learning efficiency. That is, individuals with the ability to learn efficiency do not necessarily have good retrieval fluency abilities.
In a study conducted by Luthfia and Wahyu confirmed that the discriminant validity and convergent validity of the Gl and Gr measurements were not fully accepted. Gl and Gr are different long-term memory abilities. This shows that individuals with high abilities in learning and storing information are not necessarily high in remembering and producing information that has been stored.
The event ran smoothly and interactively. Participants also actively asked questions and provided input for the development and improvement of the AJT Test in the future.
