Vitamin B: Choline Intake Improves Memory and Attention-Holding Capacity, Experts Sayfiled under: Choline Benefits Prenatal Choline Research Study
July 11, 2013 -- An experimental study in rats has shown that consuming choline, a vitamin B group nutrient found in foodstuffs like eggs and chicken or beef liver, soy and wheat germ, helps improve long-term memory and attention-holding capacity. The study, conducted by scientists at the University of Granada (Spain) Simón Bolívar University, (Venezuela) and the University of York (United Kingdom), has revealed that choline is directly involved in attention and memory processes and helps modulate them.
Researchers studied the effects of dietary supplements of choline in rats in two experiments aimed at analysing the influence of vitamin B intake on memory and attention processes during gestation and in adult specimens.
In the first experiment, scientists administered choline to rats during the third term of gestation in order to determine the effect of prenatal choline on the memory processes of their offspring. Three groups of pregnant rats were fed choline-rich, standard or choline-deficient diets. When their offspring had reached adult age, a sample of 30 was selected: 10 were female offspring of dams fed a choline-supplement, 10 had followed a choline-deficient diet and the other 10, a standard diet, acting as a control group.
This sample of adult offspring underwent an experiment to measure their memory retention: 24 hours after being shown an object all the offspring (whether in the choline-supplement group or not) remembered it and it was familiar to them However, after 48 hours, the rats of dams fed a prenatal choline-rich diet recognized the object better than those in the standard diet group, while the choline-deficient group could not recognize it. Thus, the scientists concluded that prenatal choline intake improves long-term memory in the resulting offspring once they reach adulthood.
In the second experiment, the researchers measured changes in attention that occurred in adult rats fed a choline supplement for 12 weeks, versus those with no choline intake. They found that the rats which had ingested choline maintained better attention that the others when presented with a familiar stimulus. The control group, fed a standard diet, showed the normal learning delay when this familiar stimulus acquired a new meaning. However, the choline-rich intake rats showed a fall in attention to the familiar stimulus, rapidly learning its new meaning.
The study has been undertaken by University of Granada Department of Experimental Psychology researchers Isabel De Brugada-Sauras and Hayarelis Moreno-Gudiño (also on the research staff of Simón Bolívar University together with Diamela Carias); Milagros Gallo-Torre, researcher in the University of Granada Department of Psychobiology and Director of the "Federico Olóriz" University Research Institute for Neuroscience; and Geoffrey Hall, of the Department of Psychology of the University of York. Their study has recently given rise to publications in Nutritional Neuroscience and Behavioural Brain Research.
Infants' Sweat Response Predicts Aggressive Behavior as Toddlers
Apr. 23, 2013 -- Infants who sweat less in response to scary situations at age 1 show more physical and verbal aggression at age 3, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
Lower levels of sweat, as measured by skin conductance activity (SCA), have been linked with conduct disorder and aggressive behavior in children and adolescents. Researchers hypothesize that aggressive children may not experience as strong of an emotional response to fearful situations as their less aggressive peers do; because they have a weaker fear response, they are more likely to engage in antisocial behavior.
Psychological scientist Stephanie van Goozen of Cardiff University and colleagues wanted to know whether the link between low SCA and aggressive behaviors could be observed even as early as infancy.
To investigate this, the researchers attached recording electrodes to infants' feet at age 1 and measured their skin conductance at rest, in response to loud noises, and after encountering a scary remote-controlled robot. They also collected data on their aggressive behaviors at age 3, as rated by the infants' mothers.
The results revealed that 1 year-old infants with lower SCA at rest and during the robot encounter were more physically and verbally aggressive at age 3.
Interestingly, SCA was the only factor in the study that predicted later aggression. The other measures taken at infancy -- mothers' reports of their infants' temperament, for instance -- did not predict aggression two years later.
These findings suggest that while a physiological measure (SCA) taken in infancy predicts aggression, mothers' observations do not.
"This runs counter to what many developmental psychologists would expect, namely that a mother is the best source of information about her child," van Goozen notes.
At the same time, this research has important implications for intervention strategies:
"These findings show that it is possible to identify at-risk children long before problematic behavior is readily observable," van Goozen concludes. "Identifying precursors of disorder in the context of typical development can inform the implementation of effective prevention programs and ultimately reduce the psychological and economic costs of antisocial behavior to society."
