The effects of age and attention upon reflex inhibition.

TLDR
Evidence that reflex inhibition is modulated by attention is provided, however, the relationship is complex, developmentally sensitive, and involves generalized attentive processes as well as selective attention toward specific stimuli or sensory modalities.About:

Journal ArticleDOI
Modulation of the startle response and startle laterality in relatives of schizophrenic patients and in subjects with schizotypal personality disorder: evidence of inhibitory deficits.
TL;DR: A genetically transmitted deficit in prepulse inhibition (sensorimotor gating) in patients with schizophrenia spectrum disorders, including subjects with schizotypal personality disorder and relatives of patients with schizophrenic patients are suggested.
Journal ArticleDOI
The psychological significance of human startle eyeblink modification: a review.
TL;DR: This review provides a comprehensive survey of the current literature on human startle modification and its psychological significance and directions for future research are identified regarding both cognitive and emotional modification of startle.
Journal ArticleDOI
The relationship of age to prepulse inhibition and habituation of the acoustic startle response.
TL;DR: The results do not support the theory that aging is associated with a general decline in inhibitory function and contrast with previous studies that have compared only extreme age groups and have found no effects of age on PPI.
Journal ArticleDOI
Strain and age differences in acoustic startle responses and effects of nicotine in rats
TL;DR: Age and genetic strain are important variables in the analysis of nicotine's effects on startle behaviors in rats; however, results of Experiment 2 indicated that older rats had significantly greater ASR amplitudes and PPI than younger rats.
Journal ArticleDOI
Sensory Gating and Inhibitory Function in Late-life Schizophrenia
TL;DR: Studies of prepulse inhibition, habituation, latent inhibition, and negative priming indicate marked similarities in the patterns of deficits observed in schizophrenia and in aging, suggesting that older schizophrenia patients suffer a deficit resulting from the combined effects of schizophrenia and aging.

Estimation of the Box Correction for Degrees of Freedom from Sample Data in Randomized Block and Split-Plot Designs.
Huynh Huynh,Leonard S. Feldt +1 more
TL;DR: In this article, it has been suggested that when the variance assumptions of a repeated measures ANOVA are not met, the df of the mean square ratio should be adjusted by the sample estimate of the Box correction.
Journal ArticleDOI
The More or Less Startling Effects of Weak Prestimulation
TL;DR: It is proposed that, with the aid of physiological measures taken in the interval between lead and startle stimuli, this paradigm offers a promising method of investigating different levels of central processing and the operation of a short time-constant as opposed to a long time- constant system.

Conditions under Which Mean Square Ratios in Repeated Measurements Designs Have Exact F-Distributions
Huynh Huynh,Leonard S. Feldt +1 more
TL;DR: In this paper, the character of the covariance matrix is investigated and it is shown that the matrix may exhibit a more general character than is typically implied to be essential, and the necessary and sufficient condition is the equality of variances of differences for all pairs of treatment measures assumed to be correlated.
