Response latency – the time taken to initiate or complete an action or task – is one of the principal measures used to investigate the mechanisms subserving human and animal cognitive processes. The right tails of response latency distributions have received little attention in experimental psychology. This is because such very long latencies have traditionally been considered irrelevant for ps...

The protocol developed in our laboratory for the assessment of hearing, involving the middle latency response (MLR), is described. Applications are illustrated in cases: (1) where the MLR was used to identify residual low frequency hearing and (2) where the MLR provided the only available threshold data because brainstem damage compromised the use of the ABR for hearing assessment. An understan...

This study examines e-mail response latency as an expectancy violation and explores its impact. Managers evaluate job candidates who varied in their response latency to an e-mail (1 day, 2 weeks, and silence for more than a month) and in their reward valence. As predicted by expectancy violations theory, candidate reward valence moderates the effect of response latency on variables such as appl...

Visual receptive fields of superior colliculus neurons were investigated. The latencies of "on" and "off" responses were measured and their distribution all over the field was mapped. In 36 percent of the receptive fields the latency of the "off" response was shorter than the latency of the "on" response; 19 percent of the receptive fields had almost equal latencies; in 13 percent the latency o...

This study examines e-mail response latency as an expectancy violation, and explores its impact. Managers evaluated job candidates who varied in their response latency to an e-mail (one day, two weeks, and silence for over a month), and in their reward valence. As predicted by expectancy violations theory (Burgoon & Hale, 1988), candidate reward valence moderated the effect of response latency ...

ABSTRACT Effects of varying latencies upon articulatgry productions in the stimulus-response paradigm were studied..Zero latency was compared to latency equal to stimuli and to latency with silent rehearsal of muscular movements.. Thirty children with misarticulated In from kindergarten, first, and second grades participated as subjects..Stimulus /ra/ was recorded on tape to provide 30"stimulat...

The latency and variability of latency of single-unit responses to identical visual stimulation were measured in the frontal eye field (FEF), supplementary eye field (SEF), and anterior cingulate cortex (ACC) of macaque monkeys performing visually guided saccades. The mean visual response latency was significantly shorter in FEF (64 ms) than in SEF (81 ms) or ACC (100 ms), and latency values de...

Neurons are commonly characterized by spontaneous generation of action potentials (spikes), which appear without any apparent or controlled stimulation. When a stimulus is applied, the spontaneous firing may prevail and hamper identification of the effect of the stimulus. Therefore, for any rigorous analysis of evoked neuronal activity, the presence of spontaneous firing has to be taken into ac...

This study examined the effect of response selection and execution on P3 latency during the performance of simple reaction time (RT) and stimulus-response compatibility tasks. Response time on these tasks was defined in terms of RT and movement time (MT). Event-related brain potentials were recorded from 67 female participants concurrently with the performance measures. On the simple RT task, t...

Objectives: Auditory Brain Stem Response (ABR) is a result of eight nerve and brain stem nuclei stimulation. Several factors may affect the latencies, interpeak latencies and amplitudes in ABR especially sex and age. In this study, age and sex influence on ABR were studied. Methods: This study was performed on 120 cases (60 males and 60 females) at Akhavan rehabilitation center of university...
