Summary
This study investigated if prebiotic supplements improve reading skills in children. Results showed no significant effect of the prebiotic on reading, cognition, or other measured outcomes in children with low reading scores.
Area of Science:
- Neuroscience
- Microbiology
- Developmental Psychology
Background:
- Emerging research links gut microbiota to cognitive functions.
- Understanding the gut-brain axis in children is crucial for development.
- Prebiotics as a potential modulator of gut microbiota and cognition.
Purpose of the Study:
- To assess the impact of a 3-month prebiotic supplement on reading scores in children aged 7-9 with low reading abilities.
- To explore secondary effects of prebiotics on cognition, sleep, behavior, mood, anxiety, and cortisol levels.
Main Methods:
- Proof-of-concept study design.
- Inclusion of children aged 7-9 with low reading scores.
- Comparison between a prebiotic supplement group and a placebo group over 3 months.
Main Results:
- The prebiotic supplement did not significantly improve reading scores in the studied children.
- No significant effects were observed for secondary outcomes including cognition, sleep, behavior, mood, anxiety, or cortisol levels.
Conclusions:
- In this specific sample, a 3-month prebiotic intervention did not demonstrate efficacy for improving reading skills or related cognitive and behavioral measures in children.
- Further research may be needed to explore different prebiotic formulations, dosages, or populations.

The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

01:29The Influence of Affect on Cognition

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...
