Presentation modality influences behavioral measures of alerting, orienting, and executive control [PDF]
, 2006 The Attention Network Test (ANT) uses visual stimuli to separately assess the attentional skills of alerting (improved performance following a warning cue), spatial orienting (an additional benefit when the warning cue also cues target location), and ...

Visual performance using reaction times
Lighting Research & Technology, 1988 Visual performance has been a topic of study for many years. For a variety of reasons, it has been difficult to develop a completely satisfactory model of visual performance. Recently the connection has been made between reaction time experiments and realistic studies of visual performance.

Effect of Age on Audio-Visual and Whole Body Reaction Time [PDF]
Al Ameen Journal of Medical Sciences, 2012 Objectives: With advancing age the incidence of falls and thereby morbidity goes on increasing. One important aspect of increase in the incidence of these mishaps may be the effect of age on reaction time.

Effect of handedness on visual, auditory and cutaneous reaction times in normal subjects [PDF]
Al Ameen Journal of Medical Sciences, 2013 Background & Objective: Simple reaction time is the time interval between stimulus and response. In this study the impact of handedness on auditory, visual and cutaneous simple reaction time have been investigated. Methods: 100 healthy male volunteers of

Activity in the Visual Cortex is Modulated by Top-Down Attention Locked to Reaction Time [PDF]
, 2007 We studied the correlation between perception and hemodynamic activity in the visual cortex in a change detection task. Whenever the observer perceived the location of a change, rightly or wrongly, the blood oxygenation level-dependent signal increased ...

Learning to search. The importance of eye movements in the decrease of response times during a visual choice reaction time task [PDF]
, 2016 Reaction times are often used as an indicator of the efficiency of the processes in thecentral nervous system. While extensive research has been conducted on the possibleresponse time correlates, the role of eye movements in visual tasks is yet unclear ...

The attentional drift-diffusion model extends to simple purchasing decisions [PDF]
, 2012 How do we make simple purchasing decisions (e.g., whether or not to buy a product at a given price)? Previous work has shown that the attentional drift-diffusion model (aDDM) can provide accurate quantitative descriptions of the psychometric data for ...

Visual temporal integration and simple reaction time [PDF]
Perception & Psychophysics, 1972 Intensity-time reciprocity for simple RT to foveal pulses of light was demonstrated up to 11 msec by using two experimental paradigms. The first paradigm was designed to separate two possibly confounded factors displayed by previous studies investigating the effects of increased stimulus duration on RT: (1) an asymptotic RT as a function of the ...

Maximizing decision rate in multisensory integration [PDF]
, 2011 Effective decision-making in an uncertain world requires making use of all available information, even if distributed across different sensory modalities, as well as trading off the speed of a decision with its accuracy.
