Low intensity magnetic field influences short-term memory: A study in a group of healthy students
2015
This study analyzes if an external magnetic stimulus (2 kHz and approximately 0.1 μT applied near frontal cortex) influences working memory, perception, binary decision, motor execution, and sustained attention in humans. A magnetic stimulus and a sham stimulus were applied to both sides of the head (frontal cortex close to temporal-parietal area) in young and healthy male test subjects (n = 65) while performing Sternberg's memory scanning task. There was a significant change in reaction time. Times recorded for perception, sustained attention, and motor execution were lower in exposed subjects (P < 0.01). However, time employed in binary decision increased for subjects exposed to magnetic …
P-71ADOLESCENT ETHANOL EXPOSURE INDUCES LONG-TERM MEMORY DEFICITS AND POTENTIATES THE MEMORY IMPAIRMENT INDUCED BY COCAINE WITHDRAWAL IN ADULT MICE
2015
Ethanol (EtOH) heavy-binge drinking during pubertal development elicits long-lasting neurobehavioral alterations in the adulthood such as memory impairments. An early history of EtOH consumption is correlated with higher rates of cocaine addiction in the adulthood. One consequence of cocaine withdrawal is the induction of memory deficits. The aim of the present investigation was to study the consequences of adolescent exposure …
Mobilization of short-term memory capacity for odors in discriminative tests: implication for assessors' selection
2004
Abstract The objective was to determine whether individual short-term memory capacities for odor are related to performance at discriminative tests. Two groups of 11 subjects were formed with different short-term memory for odor but equivalent sensitivity toward benzaldehyde, the aromatic compound to be detected in discriminative tests. The subject sensitivity was determined by d ′ values, derived from a detection task. Memory span for odors was the largest number of odors memorized at once. It ranged from 1 to 3 for the low memory span group and from 5 to 7 for the high memory span group. Then, subjects performed 20 triangle tests and 12 2-out-of-5 tests with two strawberry flavored soft d…
Adaptive memory representations of musical tempo and pitch
2009
Recent studies showed that the perception of extremely shifted versions of familiar pieces of music affects judgements about the original tempo and pitch. This paper aims to give an overview on musical adaptation effects (MAEs) for musical tempo and pitch. The focus is set on the questions if the recently found MAEs are generally comparable between the tempo and the pitch domain, and if they can be found to the same extent. In a series of eight empirical studies (N = 288, mean age = 26, SD = 8.6, 78 % female participants) the influence of extremely shifted versions (tempo-accelerated or pitch-shifted) of audio signals on memory representations was tested. Within this paper the focus will be…
Preventive Support for Kindergarteners Most At-Risk for Mathematics Difficulties: Computer-Assisted Intervention
2015
Weaknesses in early number skills have been found to be a risk factor for later difficulties in mathematical performance. Nevertheless, only a few intervention studies with young children have been published. In this study, the responsiveness to early support in kindergarteners with most severe difficulties was examined with two different computer programs. Two intervention groups were matched by age, visuo-spatial, and phonological working memory, as well as early number skills. After a short and intensive computerized intervention, the results indicated significant intervention effects for verbal counting Wilcoxon ES (r) = 0.46, and dot counting fluency, r = 0.52, when practiced with Grap…
Visual Distraction Effects of In-Car Text Entry Methods
2017
Three text entry methods were compared in a driving simulator study with 17 participants. Ninety-seven drivers’ occlusion distance (OD) data mapped on the test routes was used as a baseline to evaluate the methods’ visual distraction potential. Only the voice recognition-based text entry tasks passed the set verification criteria. Handwriting tasks were experienced as the most demanding and the voice recognition tasks as the least demanding. An individual in-car glance length preference was found, but against expectations, drivers’ ODs did not correlate with incar glance lengths or visual short-term memory capacity. The handwriting method was further studied with 24 participants with instru…
Sustained attention required for effective dimension-based retro-cue benefit in visual working memory
2023
In visual working memory (VWM) tasks, participants’ performances can be improved through the use of dimension-based retro-cues, which direct internal attention to prioritize a particular dimension (e.g., color or orientation) of VWM representations even after the stimuli disappear. This phenomenon is known as the dimension-based retro-cue benefit (RCB). The present study investigates whether sustained attention is required for the dimension-based RCB by inserting interference or interruption between the retro-cue and the test array to distract attention. We tested the effects of perceptual interference or cognitive interruption on dimension-based RCB when the interference (Experiments 1 and…
Teacher-child interaction quality and children's self-regulation in toddler classrooms in Finland and Portugal
2021
This study examines the association between teacher–child interaction quality and children's self‐regulation in Finnish and Portuguese toddler classrooms. The participants included 230 Finnish (M = 29; SD = 3 months) and 283 Portuguese (M = 30, SD = 4 months) toddlers and their teachers (n = 43 Finland; n = 29 Portugal). The children's behavioural self‐regulation (attention, working memory, and inhibition control) was individually tested, and the teachers evaluated the children's self‐regulation skills in the classroom. The quality of the teacher–child interactions (i.e., emotional and behavioural support and engaged support for learning) was evaluated using the CLASS‐Toddler observation in…
