effects of inhaled essential oils (eos) cannot be explained by pharmacological mechanisms alone. the study aimed to investigate the effects of pleasantness of and expectancies evoked by eos. a double-blind experiment with a within-subject design was carried out with the participation of 33 volunteering adults (15.2% male; mean age 37.7 ± 10.90 years). participants were exposed to three eos (...

BACKGROUND AND OBJECTIVES Traditional models and methods of exposure therapy utilize a fear hierarchy, whereby patients complete sets of exposures in a graduated manner, with the goal of fear habituation within and between sessions. In the current experiment, we examined whether this typical exposure paradigm was necessary to achieve clinical improvement. METHOD Fifty undergraduate participan...

The goal of this research was to test whether subjective memory experiences drive accuracy regulation decisions above and beyond objective memory indices. In four experiments (n = 115) subjective recollection (i.e., reporting "Remember" in the Remember-Know task) was dissociated from memory accuracy by manipulating retrieval during a two-alternative forced-choice recognition task: in the Match ...

Recent animal studies reveal ascending nociceptive and descending modulatory pathways that may contribute to the affective-motivational aspects of pain and play a critical role in the modulation of pain. In humans, a reliable pattern of cerebral activity occurs during the subjective experience of pain. Activity within the anterior cingulate cortex and possibly in other classical limbic structur...

In order to assess the performance of Internet telephony, it is often necessary to translate network impairments (such as packet loss, delay and jitter) into human perceived quality (which is quantified in terms of subjective voice quality ratings). Subjective quality testing is expensive and typically involves a large number of questions and humans. It is therefore important to design simple a...

Drought is a stochastic natural hazard that is instigated by intense and persistent shortage of precipitation. Following an initial meteorological phenomenon, subsequent impacts are realized on agriculture and hydrology. Among the natural hazards, droughts possess certain unique features; in addition to delayed effects, droughts vary by multiple dynamic dimensions including severity and duratio...

Over the last decade researchers have devised algorithms that can provide similarity measures between pairs of face images. These have been somewhat successful in estimating the similarities between face images under controlled conditions. However, those similarity measures do not parallel subjective similarity, as perceived by humans. In some applications it i s important to have a similarity ...

In Geng, Weiss, and Wol (2011), we pointed to the possibility that a voting mechanism may create or strengthen an entitlement e ect in political-power holders relative to a random-appointment mechanism. This comment documents that such an e ect, if it exists, is not robust.

Objectives Estimates of occupation-specific tinnitus prevalence may help identify high-risk occupations where interventions are warranted. The authors studied the effect of occupation on prevalence of bothersome tinnitus and estimated the attributable fraction due to occupation. The authors also studied how much of the effect remained after adjusting for noise exposure, education income, hearin...
