Abstract

Memory is important in a person's life to do every task given, as well as in daily life. Memory can be formed due to stimulus that is present in everyday life. Stimulus can be in the form of touch, movement, smell and sound. Not all stimuli are entered and processed by our brain and become a memory. One form of memory is visuospatial sketchpad which functions to process memory in visual and spatial form. Individuals will more easily remember a word if it contains certain emotions. In this study, the researcher's goal is to test whether there is an effect of giving words that contain emotions on visuospatial sketchpad. This research is experimental research, involving 14 students who are divided into three groups, namely groups with neutral, negative and neutral emotion words. The measuring instrument used in this study is CEFI. The analysis of this study used ANOVA test. The results showed that there were differences between groups with positive, negative and neutral emotion words (p = 0.013, F (2,11) = 6.687). This shows that. Based on the Post Hoc test, it was found that words containing negative emotions were easier to remember compared to words containing positive emotions.

Abstract

ABSTRACT Coffee is a beverage containing various bioactive components, including caffeine, which has a stimulating effect on the central nervous system. Caffeine can improve cognitive function, which plays a role in various aspects of memory such as storage, information retrieval, assessment, and perception of information. The purpose of this study was to examine the effect of caffeine on short-term memory in college students. This study used a quantitative approach with an experimental research method. There were 20 research subjects who were Satu University students from various majors. The selected subjects were divided into two groups, namely the experimental group and the control group. The experimental group was given coffee before taking the test and the control group was not given coffee before taking the test. To test the students' short-term memory abilities, it was measured using the Short-Term Memory Test Sheet (Moca-Ina). The assessment results were then processed using an independent sample T-test in SPSS software. The T-Test results showed no significant difference between the two groups. This explains that caffeine consumption does not improve short-term memory ability among students at Satu University. ABSTRAK Kopi merupakan minuman yang mengandung berbagai komponen bioaktif, termasuk kafein, yang memiliki efek stimulasi pada sistem saraf pusat. Kafein dapat meningkatkan fungsi kognitif, yang berperan dalam berbagai aspek memori seperti penyimpanan, pengambilan informasi, penilaian, dan persepsi informasi. Tujuan dari penelitian ini yaitu untuk menguji pengaruh kafein terhadap memori jangka pendek pada mahasiswa. Penelitian ini menggunakan pendekatan kuantitatif dengan metode penelitian eksperimen. Terdapat 20 subjek yang merupakan mahasiswa Universitas Satu dari berbagai jurusan. Subjek terpilih dibagi menjadi dua kelompok, yaitu kelompok eksperimen dan kelompok kontrol. Kelompok eksperimen diberikan kopi sebelum mengerjakan tes dan kelompok kontrol tidak diberikan kopi sebelum mengerjakan tes. Untuk menguji kemampuan memori jangka pendek mahasiswa, diukur melalui Lembar Tes Memori Jangka Pendek (Moca-Ina). Hasil penilaian kemudian diolah menggunakan uji T sampel independen, dalam perangkat lunak SPSS. Hasil Uji T-Test menunjukkan tidak ada perbedaan signifikan antara kedua kelompok. Hal ini menjelaskan bahwa, konsumsi kafein tidak meningkatkan kemampuan short-term memory pada mahasiswa di Universitas Satu.
