## Effects of Forward and Backward Span Trainings on Working Memory: Evidence from a Randomized, Controlled Trial ### Introduction **Overview:** Both forward and backward working memory span tasks have been used in cognitive training, but no study has been conducted to test whether the two types of trainings are equally effective. Based on data from a larger randomized controlled trial, this study tested the effects of backward span training, forward span training, and no intervention.

Introduction This EEG dataset contains the electrophysiological signal from fifty-seven obese and non-obese preteens during a stop-signal task. The stimuli were designed and administered using E-Prime software (Version 2) at Arkansas Children Nutrition Center (ACNC), Little Rock, Arkansas. The University of Arkansas for Medical Sciences (UAMS) approved the study protocol. This research was supported by USDA/Agricultural Research Service Project 6026-51000-012-06S.

# Drum Trainer Twenty-one participants learned to play two drumming patterns (pattern 1: AABA, pattern 2: AAABAA) at three different tempos (fast: 150 bpm, medium: 100 bpm, slow: 60 bpm). Responses were recorded using the f and j keys on a standard keyboard. Visual feedback in the form of a coloured circle coincided with each button press and indicated whether the response was early, on time, or late. Feedback was determined by comparing the response time, relative to the previous response, to

### Average Task Value Twelve participants completed three learning tasks. In each task the goal was to learn cue-response mappings for six cues. The cues were various coloured shapes. The possible responses were left ('d' key) or right ('k' key). There were two types of cues. Low-value cues had a feedback validity of 0.5 (i.e., a coin toss). High-value cues had a feedback validity of 0.8 (80% chance of a win if the correct action was chosen). The low-value task contained only low-value cues. T

HBN EO/EC datasets The Healthy Brain Network recorded 2952 children's eyes-open and eyes-closed EEG. Eyes-open lasted for 20 seconds, and eyes closed for 40 seconds. Because such files are difficult to process, they have been segmented here with five runs for eyes open and five runs for eyes closed. See notes in the code folder for included datasets.

### Introduction **Overview:** Subjects in the Auditory Cueing study performed a long-duration simulated driving task with perturbations and audio stimuli in a visually sparse environment. The purpose of this effort was to supplement and extend the related driving research to collect prolonged time-on-task measurements of subjects performing a driving task in a simulated environment in order to assess fatigue-based performance through novel biomarkers. Similar to the Baseline Driving
