“…We examined temporal tasks as likely moderators of the FTE as they can imply different cognitive processes (Grondin, 2010; Lewis & Miall, 2003b; Matthews, 2011; Zakay, 1990). We coded for the four main types of tasks used in the field of temporal perception: estimation, production, reproduction, and discrimination (Fernandes & Garcia-Marques, 2012; Grondin, 2010; Zakay, 1990). The reproduction and production methods (included in the present meta-analysis) are the most common.…”

“…In a second phase of the experiment, some of the stimuli are presented intermixed (between trials) with new stimuli (i.e., not presented previously). In each trial, the stimulus duration that varies between trials (e.g., 0.8, 0.9, and 1 s) is immediately judged after its offset (e.g., by using a rating scale or the psychophysics bisection method; see Allan, 1979; Fernandes & Garcia-Marques, 2012 for a review; Grondin, 2008). Results typically show that familiar stimuli have a higher probability of being judged as longer in duration than unfamiliar stimuli (see all studies included in this meta-analysis).…”

The current meta-analysis accumulates empirical findings for the familiarity temporal effect (FTE) in duration judgments (the duration of more familiar stimuli is judged to be longer than that of less familiar stimuli). It brings together data from 2 separate literatures: time perception and processing fluency. In doing so, this review offers more and stronger evidence for testing the reliability of the effect; it defines the relevant moderators for addressing the validity of the 2 main explanations for the FTE: the attentional and the fluency-attributional hypotheses. The analysis (random effect model) of a total of 128 experiments (N = 3,338) showed that the effect of familiarity on perceived short durations (seconds) is highly reliable (g = .52); the same (or a similar) effect also occurs for other fluency manipulations (g = .51). The analysis supports assumptions generated by both the attentional and the fluency-misattributional explanations, suggesting that more research is needed to understand their possible dynamic relationship. Hence, this meta-analysis provides important guidance for future research with regard to time estimates.

“…The inclusion complex obtained between β-cyclodextrin and p-cymene terpene potentiated analgesic and anti-inflammatory activities of this monoterpene [44]. The thermal instability, poor solubility in water, and the highly volatile compounds are some of the properties of essential oils or terpenes that by complexing with cyclodextrins improves its technological applicability [45,46].…”

The antioxidant and anti-inflammatory properties of Citrus flavonoids can play a key role in their activity against several degenerative diseases and particularly brain diseases. In Brazil promising studies deposited in the patents "pharmaceutical formulation" form was obtained from the inclusion of Citrus sinensis L. (orange) essential oil with β-cyclodextrin and Citrus limon (lemon) compounds and their applications in therapy of Alzheimer's disease. In this chapter, we report activities of active compounds present in the genus Citrus, which include antioxidant, anti-inflammatory, anxiolytic, insecticidal, and anticholinesterase activities. These activities are associated with some neurodegenerative diseases such as Alzheimer's disease (AD). Pharmaceutical formulations containing such compounds (for example, inhibitors such as acetylcholinesterase (AChE) of C. limon (5,8-dimethoxy-psoralen and 5,7-dimethoxycumarin) and essential oil from C. sinensis oils are reported in this chapter. These results indicate that the effects of the essential oil and substances of Citrus species are very interesting for further isolation of AChE inhibitors that can be used in the formulation of natural products for neurodegenerative diseases.

“…From planning daily routines to executing specific motor responses, many activities can be summarized as a series of successive events in time. Despite our ability to perceive the passage of time and interact with the environment accordingly, different factors can warp our sense of time, such as attention, arousal, temporal frequency and motion perception [1][2][3][4].…”

Differences in perceived duration between plausible biological and non-biological stimuli

Visual motion stimuli can sometimes distort our perception of time. This effect is dependent on the apparent speed of the moving stimulus, where faster stimuli are usually perceived lasting longer than slower stimuli. Although it has been shown that neural and cognitive processing of biological motion stimuli differ from non-biological motion stimuli, no study has yet investigated whether perceived durations of biological stimuli differ from non-biological stimuli across different speeds. Here, a prospective temporal reproduction task was used to assess that question. Biological motion stimuli consisted in a human silhouette running in place. Nonbiological motion stimuli consisted in a rectangle moving in a pendular way. Amount and plausibility of movement for each stimulus and frame-rate (speed) were evaluated by an independent group of participants. Although amount of movement was positively correlated to frame rate, movie clips involving biological motion stimuli were judged to last longer than nonbiological motion stimuli only at frame rates in which movement was rated as plausible. These results suggest that plausible representations of biomechanical movement induce additional temporal distortions to those modulated by increases in stimulus speed. Moreover, most studies that have reported neural and cognitive differences in the processing of biological and nonbiological motion stimuli acquired neurophysiological data using fMRI. The present study aimed additionally to report differences in the processing of biological and non-biological motion stimuli across different speeds using functional near infrared spectroscopy (fNIRS), a less costly and portable form of neurophysiological data acquisition.
