Anodal tDCS and High-Frequency tRNS Targeting the Occipitotemporal Cortex Do Not Always Enhance Face Perception

Megan L. Willis, Andrea I. Costantino, Michael. A. Nitsche, Romina Palermo, Davide Rivolta
2019 Frontiers in Neuroscience  
We failed to replicate previous findings of enhanced performance on face and object perception, nor extend findings to facial expression perception.  ...  In Experiment 1, using a single blind, between-subjects design in healthy volunteers (N = 53), we examined whether anodal tDCS over the occipitotemporal cortex enhanced performance on tasks involving perception  ...  The importance of replication in the field has been illustrated by emerging concerns regarding the replicability of tDCS effects, as indicated by a growing number of failures to replicate positive effects  ...

2012 PLoS ONE  
This block of observation and replication was repeated 5 times.  ...  This suggested that during observational learning of sequential hand postures MEP changed with the progress of the learning. To evaluate this idea, we performed two additional experiments.  ...  For the number of participants who correctly replicated the OK sign during the replication task, Cochran's test was performed. Data were expressed as the mean 6 one standard error.  ...

Effects of d-amphetamine in human models of information processing and inhibitory control

Mark T. Fillmore, Thomas H. Kelly, Catherine A. Martin
2005 Drug and Alcohol Dependence  
The findings highlight the complex nature of stimulant effects on human behavior and the utility of performance tasks as models of complex behavioral and cognitive functions.  ...  Information processing was measured by a rapid information processing (RIP) task and inhibitory control was measured using a stop-signal task.  ...  Acknowledgments This research was supported by grants R01 DA14079 and P50 DA005312 Drug Abuse Prevention: A Lifecourse Perspective IV, from the National Institute on Drug Abuse.  ...

Probing the causal involvement of dlPFC in directed forgetting using rTMS—A replication study

Benjamin J. Stauch, Verena Braun, Simon Hanslmayr, Tom Verguts
2020 PLoS ONE  
In this study, we attempted to solidify evidence for such a causal role of the dlPFC in directed forgetting by replicating an existing rTMS study (Hanslmayr S, 2012) in a preregistered within-participant  ...  The forgetting of previously remembered information has, for a long time, been explained by purely passive processes.  ...  B: Mean enhancement effect in percentage points (memory performance in list F2-memory performance in list R1) under dlPFC and vertex stimulation.  ...

Visual integration of direction and orientation information in autistic children

Catherine Manning, Marc S Tibber, Steven C Dakin
2017 Autism & Developmental Language Impairments  
In contrast to this view, we recently demonstrated enhanced integration of visual motion signals in autistic children compared to typically developing children.  ...  The equivalent noise tasks consisted of two interleaved conditions: a high-noise condition in which children judged the average direction or orientation of elements whose range of direction or orientations  ...  Funding The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The research was funded by a Scott Family Junior Research Fellowship  ...

Fitness effects of group merging in a social insect

J. T. Costa, K. G. Ross
2003 Proceedings of the Royal Society of London. Biological Sciences  
We confirm one prediction of the task-efficiency explanation by demonstrating a genetic basis for task thresholds of socially important behaviours in eastern tent caterpillars.  ...  By contrast, increased group size, a less commonly considered correlate of group mixing, was found to enhance individual fitness through its effects on larval growth.  ...  or defensive behaviours and consequent enhancement of colony performance.  ...

Group differences in suppression skill

Morton Ann Gernsbacher
1997 Aging, Neuropsychology and Cognition  
Many of these experiments have been replicated with other groups, which also hypothetically differ in their ability to suppress inappropriate information. Two new sets of experiments are reviewed.  ...  In the other, the prediction that less skilled comprehenders-because they are less skilled at suppression-are better able to shift to a different meaning of a homonym is evaluated.  ...  Half the participants of each skill level completed a block of 40 trials performing one task first, and then a block of 40 trials performing the other task, and we counterbalanced the order of the two  ...

The importance of material-processing interactions in inducing false memories

Jason C. K. Chan, Kathleen B. McDermott, Jason M. Watson, David A. Gallo
2005 Memory & Cognition  
To put this idea into the present context, a semantic task performed on a list of phonological associates and a phonological task performed on a list of semantic associates would be expected to enhance  ...  performance for studied words (relative to the conditions in which the type of processing afforded by the stimulus and that performed by the subject matched).  ...  , because the implicit activation of the word sleep might consequently have activated the word bed by means of spreading activation. 2.  ...
