Abstract

Inhibitory control is able to control attention by inhibiting internal tendencies and external influences. Inhibitory control is controlled by dorsolateral prefrontal cortex and anterior cingulate cortex, that can be affected by stress variable. Sing-a-Song Stress Test (SSST) is a current method to induce stress that has never been practiced in the study of inhibitory control. This study aimed to determine the effect of SSST against inhibitory control in the early adult. Between subjects, the design was applied in this study. A number of 35 participants with an age range from 17 to 21 years old were randomly assigned into an experimental group (n = 17) and control group (n = 18). Inhibitory control was measured using the Computerized Stroop Color-Word Test (CSCWT). Positive Affect and Negative Affect Schedule (PANAS) was used to conduct a manipulation check. Independent-Samples T Test explained no significant effect of stress on inhibitory control (t = -0,117; p > 0,05). Abstrak. Inhibitory control berfungsi untuk mengontrol atensi dengan cara menghambat kecenderungan internal dan pengaruh eksternal. Inhibitory control dikendalikan oleh dorsolateral prefrontal cortex dan anterior cingulate cortex, yang dapat dipengaruhi oleh variabel stres. Sing-a-Song Stress Test (SSST) merupakan metode baru dalam induksi stres yang belum pernah diterapkan pada penelitian inhibitory control. Penelitian ini bertujuan untuk mengetahui pengaruh SSST terhadap inhibitory control pada dewasa awal. Between subjects design digunakan dalam penelitian ini. Sebanyak 35 partisipan berusia 17 sampai 21 tahun dikelompokkan secara acak ke dalam kelompok eksperimen (n = 17) dan kelompok kontrol (n = 18). Inhibitory control diukur melalui Computerized Stroop Color-Word Test (CSCWT). Positive Affect and Negative Affect Schedule (PANAS) digunakan untuk melakukan cek manipulasi. Independent-Samples T Test menunjukkan adanya pengaruh yang tidak signifikan antara stres dan inhibitory control (t = -0,117; p > 0,05).

Abstract

Female and male rats use different landmarks to find foods in the radial arm maze. The aim of this research was to test the effect of environmental enrichment on spatial memory of male and female rats. Twenty-two male and 22 female Wistar rats (Rattus novergicus) were allocated into eight groups. Spatial memory was measured after 60 days of environmental enrichment. It was hypothesized that rats in environmentally enriched groups had better spatial memory. The analysis was done using SPANOVA (Mixed Design ANOVA). It was found that sex had an effect on spatial memory.Abstrak : Tikus jantan dan betina menggunakan landmark (penanda ligkungan) yang berbeda dalam menemukan makanan pada radial arm maze. Penelitian ini bertujuan menguji pengaruh pengkayaan lingkungan terhadap ingatan spasial pada tikus jantan dan betina. Duapuluh dua ekor tikus jantan dan 22 ekor tikus betina galur Wistar terbagi dalam delapan kelompok diukur ingatan spasialnya setelah mendapat pengkayaan lingkungan selama 60 hari. Hipotesis yang diajukan dalam penelitian ini bahwa kelompok yang mendapat pengkayaan lingkungan memiliki ingatan spasial lebih baik, diuji dengan menggunakan SPANOVA (ANOVA Mixed Design). Hasil analisis menunjukkan tidak ada interaksi antara pengkayaan lingkungan dan jenis kelamin terhadap ingatan spasial. Tidak ada pengaruh perlakuan terhadap ingatan spasial. Ada pengaruh jenis kelamin terhadap ingatan spasial.

Abstract

One of the advantage of e-learning method is the flexibility of embedding audio-visual materials, however whether this goal-irrelevant stimuli would distract the users instead and hinder their performance is generally unknown. The present study aimed to investigate the effects of emotional distraction (ED) on the declarative memory performance. The study was conducted using the within-subject experiment on 38 students aged 18-21 years (20 males). Declarative memory was measured using a Word-Pair Association (WPA) task. ED is given using the International Affective Pictures System (IAPS) and International Affective Digitized Sounds (IADS) grouped based on their valence (neutral, positive, and negative). Measurement of physiological responses was done by measuring Galvanic Skin Responses (GSR), and Electroencephalography (EEG) with Frontal Alpha Asymmetry (FAA) index. Result: significant difference on the WPA score of which Positive is lower than Neutral condition (p = 0.011), but only on the group which the positive block were presented first. From the GSR data, significant main effect of the order of experimental block regardless of the ED valence (p < 0.001; F = 16.045), the first block elicits significantly higher GSR amplitude compared to second (p < 0.001; t = 4.94) and third (p = 0.001; t = 3.90). Meanwhile, the FAA index showed no significant difference (p = 0.654; F = 0.433).
