Reaction times for naming successive letters of the alphabet for monolinguals and bilinguals
… of unilinguals of both languages on a reaction-time task involving letters of the alphabet. This research also wanted to determine if there was any difference between subgroups of bilinguals (compounds and coordinates) on such a task."

The effects of emotional interrupt on reaction times in primary and secondary psychopathy
… response task, in this study, is presented as a reaction time task. The participants either choose the left or right finger as a response to the circle or square on the screen, respectively. The emotional images that are presented before and after the motor response task are presented as either …

The application of decision times and reaction times in the construction of latency weighted test scores
… test scores was investigated. Three times were measured on each test item by the computer system which administered two tests. The times recorded were: the reading time which the student used to read the stem of the question; the decision time which the student used to read the …

An investigation of the effects of a rest period on simple reaction times of kindergarten children
… on kindergartners’ performance in a simple reaction time situation. Effects of sex, class, time of measurement and practice on simple reaction time were also factors investigated in the present study. The sample consisted of 32 children ranging in chronological age from 62 months to 74 …

Use Your Head to Get the Picture: an Investigation of Working Memory and Idiom Processing
… word predictability were associated with faster reaction times for low working memory participants while familiarity and literal plausibility were associated with faster reaction times for high working memory participants. In Experiment 2, familiarity was associated with faster reaction times for …

The influences of preparation and brain states on the time-course of oculomotor control in visual selection
… period may influence performance and saccadic reaction times in a visual search task. Using a similar design, MEG and eye movements were measured concurrently. Results revealed that slow oculomotor reaction times in the non-salient target condition were predicted by an overall increase of power …

Alcohol and cognition: ego threat as a moderator
… impaired performance, as evidenced by slower reaction times during visual search. An interaction effect emerged, with the combination of alcohol and ego threat further compromising reaction times. Interestingly, higher baseline impulsivity correlated with faster reaction times when sober. …

The Effects of the Phenomenon of the Psychological Refractory Period Upon College Athletes and Non-Athletes
… is no significant difference of single left hand reaction times between the athlete and non-athlete groups. 2. There is no significant difference of single right hand reaction times between the athlete and non-athlete groups. 3. There are no significant differences of the refractory time means at …

Exploring spatial memory in children with autism and ADHD
… in neurotypicals, ASD and ADHD children. In a reaction-time accuracy task, children (N = 117) were presented with a grid containing twenty-five individual places. In the presentation phase, children saw different categories of object-in-places which varied from technical to social role play …

Developments in signal processing for computerised diagnosis in clinical neurophysiology
… the preprocessing of the CNV) and the subjects reaction times to an acoustic stimulus. The CNV waveforms were initially preprocessed. This reduced the effects of background electroencephalogram and ocular artefact potentials. The CNV waveforms were then processed using a method which involved …

What's in a game: Examining the effect of video game experience across reading and attentional domains
… was associated with faster lexical reading reaction times. In Experiment 2, we tested whether action video game experience was related to performance in an orthographic-phonological decision paradigm, and found action video game experience was associated with slower reaction times when …

The Feedback-Related Negativity is a Time-Dependent Brain Mechanism that Facilitates Aversive Learning: Implications for the Reinforcement Learning FRN Hypothesis
… large numbers of trials. I examined variation in reaction times and feedback-locked cortical activity over time as a function of PE to critically examine theories indicating that PE signals drive time-dependent learning. We recorded EEG while participants completed a novel reinforcement task that …

Do College Students with Public Speaking Anxiety Show an Attentional Bias Toward Threat?
… paradigm with threatening and neutral words. Reaction times to dot-probes on threatening and neutral trials were compared between the two groups. Results indicated that, contrary to expectations, high and low speech anxious participants did not differ in their mean reaction times to threat …

Neuropsychological effects of anxiety without depression on facial affect perception
… counter to hypotheses, where anxious subjects' reaction times to affective valences were slower than nonanxious subjects. Additionally, anxious subjects failed to demonstrate a negative affective bias for neutral stimuli. Results are discussed in terms of arousal theory, where anxious subjects …

Psychometric And Experimental Investigation Of Impulsivity, Rumination, Revenge, And Forgiveness
… used in Study 1 would predict participants' reaction times on a modified Stroop task. Specifically, participants (N = 145) completed the same self-report measures used in Study 1. After completing the self-report measures, 100 participants completed a modified Stroop task where they were …

The effects of stressful life experiences and maladaptive daydreaming on selective attention among young adults
… associated with MD, as well as with increased reaction times in the Emotional Stroop. There was an indirect effect of ACEs on total reaction time through MD. High levels of MD moderated the relationship between AAEs and SA by decreasing reaction times. Findings suggest a complex mechanism in …

Gender Differences in Task Switching: An Event-Related Potential Study
… differences in several brainwaves and behavioral reaction times between males and females in relation to task switching. Previous research has shown gender differences in various aspects of cognition including task switching. Task switching refers to the ability to cognitively switch from …

Development of a microwave-assisted epoxide aminolysis and investigation of the aza-cope rearrangement--mannich cyclization for alkaloid synthesis
… gives SN2 selectivity. Additionally, long reaction times are often required to obtain adequate yields. We have demonstrated that microwave heating reduces reaction times for the aminolysis of both reactive and unreactive, sterically hindered epoxides. These reactions were accomplished with …
