“…The latter is a methodological improvement over previous studies using end-of-day reports. In addition, our dataanalytic approach of specifying three-level multilevel models with observations nested within days nested within individuals took into account the possibility that nightly rests can serve as a natural emotion regulator (Minkel et al, 2012;Walker & van der Helm, 2009). and, thus, delimit the interpretability of comparisons of affective states within individuals from one day to the next.…”

Two studies investigated the overpowering hypothesis as a possible explanation for the currently inconclusive empirical picture on age differences in affective responding to unpleasant events. The overpowering hypothesis predicts that age differences in affective responding are particularly evident in highly resource-demanding situations that overtax older adults' capacities. In Study 1, we used a mobile phone-based experience-sampling technology in 378 participants 14 -86 years of age. Participants reported their momentary negative affect and occurrences of unpleasant events on average 54 times over 3 weeks. In Study 2, a subsample of 92 participants wore an ambulatory psycho-physiological monitoring system for 24 hr while pursuing their daily routines and additionally completed an average of 7 mobile phone-based experience-sampling reports. Affective responding was analyzed by comparing, within persons, affective states in situations without and with preceding unpleasant events. Results support the overpowering hypothesis: When dealing with complex unpleasant events that affected multiple life domains, both psychological (Study 1) and cardiovascular (Study 2) responding to unpleasant events were more pronounced the older the participants were. When dealing with circumscribed unpleasant events, however, no age differences in psychological responding were observed (Study 1), and cardiovascular responding was even less pronounced the older the participants were (Study 2). These findings are consistent with the notion of preserved affect regulation throughout adulthood, as long as the resource demands exerted by an event do not overtax the individual's capacities. We conclude that the overpowering hypothesis can bridge previously opposing positions regarding age differences in affective responding.

“…A third experiment showed no effect of 100 mg, 200 mg or 300 mg theobromine delivered in a cocoa-based beverage on mood state or vigilance [27]. Hrs of sleep the night before testing was not considered in any of these studies despite strong evidence that variations in sleep can result in meaningful changes in mood and cognitive performance [28][29][30].…”

Acute effects of brewed cocoa consumption on attention, motivation to perform cognitive work and feelings of anxiety, energy and fatigue: a randomized, placebo-controlled crossover experiment

et al. 2017

Background: Acute effects of caffeinated and non-caffeinated cocoa on mood, motivation, and cognitive function are not well characterized. The current study examined the acute influence of brewed cocoa, alone and with supplemental caffeine, on attention, motivation to perform cognitive tasks and energy and fatigue mood states. Methods: A randomized, double-blinded, within-subjects crossover trial was conducted with four 473-milliliter brewed beverage treatments: cocoa, caffeinated cocoa (70 milligrams caffeine total), placebo (flavored and colored brewed water) and positive control (placebo plus 66 milligrams caffeine, "caffeine alone"). Participants (n = 24) were low consumers of polyphenols without elevated feelings of energy. Before and three times after beverage consumption, a 26-minute battery was used to assess motivation to perform cognitive tasks, mood and attention (serial subtractions of 3 and 7, the continuous performance task, and the Bakan dual task) with a 10-minute break between each postconsumption battery. The procedure was repeated with each beverage for each participant at least 48 h apart and ±30 min the same time of day. Data were evaluated using Treatment X Time analysis of covariance controlling for hours of prior night's sleep. Results: Compared to placebo, cocoa reduced overall false alarm errors progressively across time with 0.92, 1.44 and 2.35 fewer false alarms on average 22-48, 60-86 and 98-124 min post-consumption (η 2 = 0.08, p = 0.019). Caffeinated cocoa: (i) attenuated the anxiety-provoking effects of cognitive testing found after drinking caffeine alone (η 2 = 0.064, p = 0.038), and (ii) increased accuracy (η 2 = 0.085, p = 0.01) and reduced omission errors (η 2 = 0.077, p = 0.016) on the Bakan primary task compared to cocoa alone.

Study 1 comprised 16 men and women, in a within Ss counterbalanced design (normal versus sleep restriction). Study 2 involved 12 different men and women undergoing three conditions in a latin square design.Conditions were as for Study 1, with a replicated sleep restriction. All conditions incorporated a sugar-free drink given 30 min before testing, with one restriction including 80mg caffeine (double blind). Both studies showed significant impairments to serving accuracy following sleep restriction, particularly with women. At this dose, caffeine had no beneficial effect. These results reflect laboratory based, non-sports related findings pointing to detrimental effects of sleep loss on executive function. 211
