Attempts were made in three experiments to induce human subjects to yawn reliably in the laboratory. In subjects who believed they were not observed, reading about yawning did increase their frequency of yawning, compared to reading about scratching or day dreaming. In the second experiment, performing a spontaneous yawn decreased skin conductance, but "faked" yawns did not have this effect. In subjects under observation during the third experiment neither boredom, vigilance, nor reading about… Expand
ON THE CONTEXT OF YAWNING: WHEN, WHERE, AND WHY?
ABTRACT From personal logs kept by 28 subjects of their yawning during 1 week we found that yawns occurred during the hours of transitions between sleeping and waking. During the day yawns wereExpand
Field observations of yawning and activity in humans
TLDR
In a second study, data from daily logs kept by 45 subjects confirmed previous findings that yawning frequency is unrelated to prior amount of sleep, or to times of awaking or retiring. Expand
On yawning and its functions
  • R. Baenninger
  • Psychology, Medicine
  • Psychonomic bulletin & review
  • 1997
The forms and behavioral correlates of yawning are described, and the phylogenetic and ontogenetic aspects of the act are examined with particular attention to its possible functions. Much evidenceExpand
Yawning: a cue and a signal
TLDR
It is suggested that non-directed yawning functions as a cue in cage mate rats and directed yawning as a signal in stranger rats might indicate the physiological capacity of rats in male-male conflicts. Expand
Interplay between yawning and vigilance: a review of the experimental evidence.
TLDR
The data do not support an arousing effect of yawning or a role in regulation of vigilance or autonomic tone, and the hypothesis that yawning increases the arousal level during sleepiness is rejected. Expand
Why do we yawn?
TLDR
It is found that theories ascribing a physiological role to yawning (such as the respiratory, arousal, or thermoregulation hypotheses) lack evidence, and the notion that yawning has a communicative function involved in the transmission of drowsiness, boredom, or mild psychological stress receives increasing support from research in different fields. Expand
Occurrences of Yawn and Swallow are Temporally Related
TLDR
A greater-than-fivefold increase in rest (saliva) swallowing rate during the 10-s period immediately following contagious yawning elicited in 14 adult humans through the viewing of videotaped yawn stimuli is shown. Expand
Neuroscience and Biobehavioral Reviews
Yawning is a phylogenetically old behaviour that can be observed in most vertebrate species from foetal stages to old age. The origin and function of this conspicuous phenomenon have been subject toExpand
One thousand yawns.
TLDR
Some of the experimental and observational research that has been done on yawning and contagious yawning in primates—human and nonhuman— and to a lesser extent in other species are reviewed. Expand
Why do we yawn? The importance of evidence for specific yawn-induced effects
TLDR
Critics of the review on the function of yawning are addressed and the argument that from an evolutionary perspective, yawns must have a "primitive" physiological function arises from imprecise reasoning. Expand

The hypothesis that subjects yawn more while observing uninteresting than while observing interesting stimuli was tested by comparing the yawns produced by 17- to 19-year-old college freshmen whileExpand
Self-report as a valid measure of yawning in the laboratory
The validity of self-report for studying yawning in the laboratory was examined. Thirty undergraduate students were assigned to one of two groups. Both groups recorded their own yawns using anExpand
Is yawning a cholinergic response?
TLDR
Observations make some observations that indicate the involvement of a central cholinergic response in yawning, and the relation of these observations to the basic mechanism of yawning has not been studied. Expand
Serotonergic modulation of Yawning
TLDR
Yawning induced by intraperitoneal injection of physostigmine in infant or adult rats is potentiated by Lu 10-171, a selective serotonin uptake inhibiting drug, which, by itself, does not induce yawning. Expand

Abstract The aim of this study was to test the hypothesis that sex differences in primate yawning are related to size dimorphism in canine teeth. Data were collected on yawning by a primate species (Expand
Yawning: no effect of 3-5% CO2, 100% O2, and exercise.
TLDR
The CO2/O2 hypothesis was rejected because breathing neither pure O2 nor gases high in CO2 had a significant effect on yawning although both increased breathing rate. Expand

TLDR
It is suggested that calcium might be the second messenger which mediates the expression of penile erection and yawning induced by oxytocin. Expand

TLDR
Sexual behavior of gonadectomized adult rhesus macaques given no hormonal treatment, treated with estradiol benzoate, and treated with testosterone propionate gave little evidence of masculinization, but males displayed significantly greater rates of sexual behavior than hermaphrodites or females.
