“…Considerable effort has been devoted to studying the relationship between body temperature and human performance [49][50][51]. It has been reported that cognitive function is improved by increasing body temperature slightly above the normal temperature of 37℃ and that cognitive function is reduced by decreasing body temperature below normal [52,53].…”

Background: The high protein (HP) breakfast reduced gastric emptying and the most satiating macronutrient appears to be dietary protein.Few studies have investigated the effects of protein to energy ratio in breakfast on mood, alertness and attention. Objective: This study was designed to investigate whether the HP breakfast is more beneficial to mood, alertness and attention of the healthy undergraduate student than adequate-protein (AP) breakfast through the rising body temperature and remaining stable blood glucose or through other physiologic processes. Methods: Thirteen healthy male undergraduate students (18 -23 y) were studied in a double-blind, randomized crossover design. Blood samples, body temperature, satiety, mood and Continuous Performance Test (CPT) were assessed after the consumption of two isocaloric breakfasts that differed in their protein and carbohydrate content: an HP breakfast (50%, 30%, and 20% of energy from protein, carbohydrate, and fat, respectively) or an AP breakfast (10%, 70%, and 20% of energy from protein, carbohydrate, and fat, respectively). Results: Consumption of an HP breakfast resulted in more steady glucose and insulin than AP breakfast consumption (p < 0.05). Satiety scores and body temperature were higher after HP breakfast consumption (p < 0.05). And most important, the positive mood and CPT scores were higher after HP breakfast than after AP breakfast intake (p < 0.05). Conclusion: HP breakfast can effectively stabilize postprandial serum glucose concentration and elevate postprandial temperature of healthy male undergraduate students. Our present findings demonstrate the relationship between HP breakfast and mood, alertness and attention. This study indicated that HP breakfast may enhance human performance probably by increasing the thermic effect of a food and elevating body temperature.

“…Analogous patterns of cognitive impairment and adverse mood changes have been reported in humans. Acute cold exposure during cognitive testing degraded performance, including vigilance, reaction time, reasoning skills and short-term memory (e.g., see Coleshaw et al 1983;Mahoney et al 2007;Patil et al 1995;Shurtleff et al 1993). In addition to decrements in performance on a 4-choice reaction task and impairment in delayed match-to-sample tasks, cold-stressed individuals also reported higher levels of tension, confusion and depression on the subscale of the Profile of Mood States questionnaire, and had significantly higher "total mood disturbance" scores (Mahoney et al 2007).…”

Chronic intermittent cold stress and serotonin depletion induce deficits of reversal learning in an attentional set-shifting test in rats

Rationale-Chronic stress perturbs modulatory brain neurotransmitter systems, including serotonin (5-HT), and is a risk factor for psychiatric disorders such as depression. Deficits in cognitive flexibility, reflecting prefrontal cortical dysfunction, are prominent in such disorders. Orbitofrontal cortex (OFC) has been implicated specifically in reversal learning, a form of cognitive flexibility modulated by 5-HT.Objectives-Assess the effects of chronic intermittent cold (CIC) stress, a potent metabolic stressor, on performance of rats in an attentional set shifting test (AST). Assess a possible role for serotonin in CIC-induced deficits, and test the effects of acute serotonin reuptake blockade. Methods-MaleSprague-Dawley rats were exposed to CIC stress (14 days × 6 hr/day at 4 °C) before testing on the AST. In subsequent experiments, brain 5-HT was depleted in naïve rats with para-chlorophenylalanine, or 5-HT release was increased acutely in CIC-stressed rats with citalopram (5 mg/kg, s.c.) given 30 min prior to the first reversal task. Microdialysis was used to assess CICinduced changes in 5-HT release in OFC during testing.Results-CIC-stressed rats exhibited a selective impairment on the first reversal task in the AST. 5-HT depletion induced a similarly selective deficit in reversal learning. The CIC-induced impairment in reversal learning was attenuated by acute 5-HT reuptake blockade. 5-HT release was reduced in OFC of CIC-stressed rats during behavioral testing.Conclusions-The CIC stress-induced impairment of cognitive flexibility may involve dysregulation of 5-HT modulatory function in OFC. Such deficits may thus model relevant symptoms of neuropsychiatric disorders that respond positively to SSRI treatment.

We evaluate the situational impairments caused by cold ambient temperature on fine-motor movement and vigilance during mobile interaction. For this purpose, we tested two mobile phone applications that measure fine motor skills and vigilance in controlled temperature settings. Our results show that cold adversely affected participants' fine-motor skills performance, but not vigilance. Based on our results we highlight the importance of correcting measurements when investigating performance of cognitive tasks to take into account the physical element of the tasks. Finally, we identify a number of design recommendations from literature that can mitigate the adverse effect of cold ambiance on interaction with mobile devices.
