“…For example, alcohol has failed to affect visuospatial working memory at moderate (.06%; Rose and Duka, 2008) and heavier (.08%; Pihl et al, 2003) doses in samples that included, but unlike the present study were not restricted to, drinkers 18-20 years of age. In addition, there are reports that alcohol does not always affect short-term memory capacity in younger drinkers at moderate (Grattan-Miscio and Vogel-Sprott, 2005) and heavier doses (Tiplady et al, 2009). Thus, although alcohol's acute effects are not always evident in performance on tasks of executive function, alcohol may be affecting only certain complex cognitive processes.…”

ABSTRACT. Objective: Alcohol's effects on executive functioning are well documented. Research in this area has provided much information on both the acute and chronic effects of alcohol on processes such as working memory and mental fl exibility. However, most research on the acute effects of alcohol is conducted with individuals older than 21 years of age. Using fi eld recruitment methods can provide unique empirical data on the acute effects of alcohol on an underage population. Method: The current study examined the independent effects of acute alcohol intoxication (measured by breath alcohol content) and chronic alcohol use (measured by years drinking) on a test of visuomotor performance and mental fl exibility (Trail Making Test) among 91 drinkers ages 18-20 years recruited from a fi eld setting. Results: Results show that breath alcohol predicts performance on Trails B, but not on Trails A, and that years drinking, above and beyond acute intoxication, predicts poorer performance on both Trails A and B. Conclusions: These data suggest that, independent of the acute effects of alcohol, chronic alcohol consumption has deleterious effects on executive functioning processes among underage drinkers. Our discussion focuses on the importance of these data in describing the effect of alcohol on adolescents and the potential for engaging in risky behavior while intoxicated. (J. Stud.

Background: Disruptive effects of caffeine on sleep have previously been reported, although measures of next-day mood and performance have rarely been included. The present study aims to evaluate the effects of caffeine on sleep and associated next-day effects in a naturalistic field setting. Methods: Nineteen participants (daily caffeine intake 0-141 mg), assessed as good sleepers, took part in a randomized, placebo-controlled, double-blind, 2-week crossover study to assess the effects of bedtime caffeine use (250 mg) on sleep and next-day cognitive performance and mood, which were assessed on a mobile phone in the morning and afternoon. Sleep was assessed objectively (actiwatch) and subjectively (sleep diary). Results: Caffeine's effects on sleep were largely restricted to the first day of administration, with actigraphically measured reduced sleep efficiency, increased activity score and fragmentation index, decreased self-rated sleep quality, and an increased occurrence of participants waking early; only decreased sleep efficiency remained over the week. Effects on next-day performance and mood were evident over the whole week, although despite disrupting sleep, accuracy on a working memory task was higher after caffeine than placebo administration. Conclusions: Caffeine disrupted sleep, although when assessing next-day performance, which may have been affected by the presence of residual caffeine, performance appeared better after caffeine compared to placebo, although this was most likely due to prevention of the effects of overnight withdrawal from caffeine rather than representing a net benefit. Furthermore, partial tolerance developed to the effects of caffeine on sleep.

“…These cell phones are typically modified such that participants can use them only in specific ways, such as answering phone calls and text messages from specific numbers (e.g., Tiplady, Oshinowo, Thomson, & Drummond, 2009). Additionally, outgoing calls to participants may need to be conducted manually by trained research assistants, rather than by a computer.…”

TelEMA: a low-cost and user-friendly telephone assessment platform

Ecological momentary assessment (EMA), or the repeated assessment of individuals' behaviors and experiences over time, is a methodologically advantageous approach to the study of psychological constructs. Recently, advances in computer technology have allowed for EMA research to be conducted in a more convenient, automated, and secure manner by administering surveys on participants' telephones and storing the results directly to a central server. The present article introduces TelEMA, an easy-touse, low-cost telephone assessment platform for clinical and research applications. A single server running TelEMA can be shared among many experimenters, studies, and participants simultaneously. TelEMA routes telephone calls and text messages through a third-party service, so experimenters may conduct studies with no up-front cost or technical expertise. TelEMA provides a secure Web interface for experimenters or clinicians to design studies, enroll participants, monitor compliance, and collate response data from anywhere. Participants complete surveys using their own telephones. Surveys may contain keypress or voice recording questions, and the timing and content of each survey may be randomized and customized. A pilot study was conducted in which individuals used the TelEMA system to complete four randomly timed surveys per day for one week; the surveys assessed state affect and social anxiety. Results indicated that participants found TelEMA easy to use and secure, and compliance rates were on par with other EMA methods using mobile devices. Overall, Tel-EMA is a practical and robust system that enables fast and inexpensive deployment of EMAs.

Alcohol and Cognitive Function: Assessment in Everyday Life and Laboratory Settings Using Mobile Phones

Abstract: We found that mobile phones allowed practical research on cognitive performance in an everyday life setting. Alcohol impaired function in both laboratory and everyday life settings at relevant doses of alcohol.
