Creatine Supplementation and Cognitive Performance in Elderly Individuals

ABSTRACT

The purpose of this study was to examine the effect of creatine supplementation on the cognitive performance of elderly people. Participants were divided into two groups, which were tested on random number generation, forward and backward number and spatial recall, and long-term memory tasks to establish a baseline level. Group 1 (n?=?15) were given 5 g four times a day of placebo for 1 week, followed by the same dosage of creatine for the second week. Group 2 (n?=?17) were given placebo both weeks. Participants were retested at the end of each week. Results showed a significant effect of creatine supplementation on all tasks except backward number recall. It was concluded that creatine supplementation aids cognition in the elderly.     

FORGETTING THE FORGOTTEN ONES

Haim Gouri’s poem “Hanishkahim” (The Forgotten Ones) has appeared in several versions and in a number of collections. Suggesting the noble heroism of soldiers dying in battle, this poem has become an example of the symbolic repertoire employed to enforce national myths. As part of the “Palmah generation” of poets, Gouri’s own life, as well as the imagery of the poetry, articulates the ideals of the sabras who fought and died in the Israeli War of Independence. However, this poem also challenges these myths. “Hanishkahim” questions the State’s memorialization of military heroism while ignoring those soldiers, particularly the disabled, who destabilize the authority of national narratives. In shorter editions of this poem, Gouri’s critique of war commemoration is obliterated. This article examines Gouri’s poem in light of the role editing plays in shaping ideological discourse.     

Buddhism in war: A study of cause and effect from Sri Lanka

In this article, I explore two attitudes towards war present among Buddhists in contemporary Sri Lanka: support for an all‐out military victory over the Liberation Tigers of Tamil Eelam (LTTE) and support for a ceasefire followed by a negotiated settlement. After a phenomenological presentation of the two approaches, I turn to the factors that have conditioned them. I argue that canonical narrative is drawn on both to support the war and to reject it and then look at more recent colonial history to provide further data, particularly to the dynamic undergirding Buddhist support for war. In the nineteenth century, under British rule, one significant ‘other’ for Sri Lankan Buddhists was the Christian. A pattern of spirited defence developed in the face of what was seen as humiliation and betrayal at the hands of Christians. This pattern, the paper suggests, can throw light on responses in the present to the very different ‘other’, the LITE.     

Stick to the script: The effect of witnessing multiple actors on children’s imitation

What kinds of cues increase imitative fidelity in early childhood? The effects of multiple models and verbal framing were examined in preschool children (N = 259, 3–6-year-olds). Each participant was presented with one of eight possible combinations of type of modeling and verbal frame. The type of modeling involved: (i) a single model offering two demonstrations, (ii) two successive models each offering a single demonstration, (iii) two synchronous models each offering two demonstrations, or (iv) two synchronous models each offering a single demonstration. The verbal frame preceding the demonstrations emphasized either the instrumental outcome of the actions or their conventionality. Imitative fidelity was highest for the synchronous models (types iii and iv) and lowest for the single model (type i). Imitative fidelity was also higher for the convention-oriented than the outcome-oriented frame and higher for older than younger children. Children also provided more conventional explanations for their actions after viewing the synchronous models and after the convention-oriented framing. The results indicate that children’s imitative fidelity depends on the number of actors and the way the actions are framed.     

An Idiographic Examination of Day-to-Day Patterns of Substance Use Craving,Negative Affect,and Tobacco Use Among Young Adults in Recovery

Psychological constructs, such as negative affect and substance use cravings that closely predict relapse, show substantial intraindividual day-to-day variability. This intraindividual variability of relevant psychological states combined with the “one day at a time” nature of sustained abstinence warrant a day-to-day investigation of substance use recovery. This study examines day-to-day associations among substance use cravings, negative affect, and tobacco use among 30 college students in 12-step recovery from drug and alcohol addictions. To account for individual variability in day-to-day process, it applies an idiographic approach. The sample of 20 males and 10 females (mean age = 21) was drawn from members of a collegiate recovery community at a large university. Data were collected with end-of-day data collections taking place over an average of 26.7 days. First-order vector autoregression models were fit to each individual predicting daily levels of substance use cravings, negative affect, and tobacco use from the same 3 variables 1 day prior. Individual model results demonstrated substantial interindividual differences in intraindividual recovery process. Based on estimates from individual models, cluster analyses were used to group individuals into 2 homogeneous subgroups. Group comparisons demonstrate distinct patterns in the day-to-day associations among substance use cravings, negative affect, and tobacco use, suggesting the importance of idiographic approaches to recovery management and that the potential value of focusing on negative affect or tobacco use as prevention targets depends on idiosyncratic processes.     

Facial expressions,smile types,and self-report during humour,tickle, and pain

The nature of ticklish smiling and the possible emotional state that accompanies it have been pondered since the ancient Greeks. The present study is arguably the first to systematically examine facial behaviour and self-reports of emotion in response to tickling. Using a within-participants design, 84 participants' responses to being tickled were compared to their responses when experiencing a painful stimulus and their responses to comedy. Overall results for both self-report and facial action coding showed that the tickle condition elicited both pleasure and displeasure. Facial action during tickling included “Duchenne” smiles plus movements associated with negative emotions. Results suggest that tickle-induced smiling can be dissociated from positive affect. Accounts of tickle are discussed.     

Longitudinal change and longitudinal stability of individual differences in children's emotion understanding

Individual differences in children's emotion understanding have been intensively investigated during the past decade. Theses studies suggest that individual differences emerge quite early, are present among both preschool and school-aged children, are not restricted to the understanding of some specific components of emotions, correlate with other characteristics of the individual and his or her social network, and may persist even after an intervention programme. However, because few of these studies had a longitudinal design we know little about change and stability in these individual differences especially among school-aged children when several components of emotion understanding, both simple and complex, are assessed. Therefore, the two aims of the present study were to examine both change and stability in individual differences among school-aged children in their understanding of several components of emotion. For this purpose, 42 children aged 7, 9, and 11 years at Time I were retested 13 months later at Time II on several components of emotion understanding, both simple and complex, with the Test of Emotion Comprehension (TEC). The results show that: (1) The two younger age groups clearly improved their overall level of emotion understanding; (2) this improvement was not equally distributed across the different components of emotion understanding; (3) individual differences in the overall level of emotion understanding were very stable, with overall level at Time I being a good predictor of overall level at Time 2; and (4) this stability was observable for both simple and complex components of emotion understanding.     

Persistence of preference for a flavor presented in simultaneous compound with sucrose

Rats exposed to a simultaneous compound of a flavor and sucrose subsequently exhibited a preference for the flavor over water. This preference persisted across repeated testing even though the flavor was presented in the absence of sucrose. The preference did, however, extinguish if the rats were hungry when trained or tested, or if they had been reexposed to sucrose between training and test. Though failing to extinguish the preference, presentation of the flavor outside the compound protected it from the effects of sucrose devaluation, indicating that these presentations extinguished the within-compound association between the flavor and sucrose. The authors conclude that the hedonic reaction elicited by sucrose imbues the flavor with the same hedonic properties, and these properties maintain the preference independently of the flavor-sucrose association.
