In the scientific method, the term measurement refers to a scale, instrument or unit that is applied to an event or object to study it and prove a hypothesis. Additionally, measurements can be of different types as these are consider as quantitative if it deals with numerical information, as qualitative if they deal with patterns that are not expressed by numbers; as reliable if the results found with a measurement is replicable and verifiable and as valid in the case the measure directly addresses or measures the phenomenon, event or object that is being studied. Therefore, a measure that actually measures what it is intended to measure is considered as a valid measurement.
In the context of Levinson’s theory on seasons that a person goes through, all of these underlying factors contribute to Keisha’s "life structure".
Psychologist Daniel Levinson built up a complete theory of grown-up advancement, alluded to as the Seasons of Life hypothesis, which distinguished stages and development that happen well into the grown-up years.
His theory is included succession like stages. Each stage is formed by an occasion or activity that leads into the following stage.
The correct answer to this open question is the following.
Although the are no options attached, we can say the following.
When looking back at the course of her relationship, Helga realized that she has not been happy with her boyfriend's behavior for quite some time. Helga is taking into account the aspect of the social exchange theory known as reciprocity or the expectations of the relationship.
That is why Helga considers that his boyfriend's behavior is not reciprocal to Helga's. Helga was expecting more of her boyfriend but probably his expectations are not the same as Helga's. That is why he seems not to be committed as Helga is. This social exchange theory assumes that people are in a relationship to maximize their satisfaction because relationships produce great gratification.
The independent variable in the given experiment in testing the hypothesis is the pixie sticks as it could stand independently, without having to rely to another variable. The dependent variable is determining the reading speed of which this will be dependent on the independent variable in showing its effect or result.
The correct answer is letter C
LTP is the most recognized cellular mechanism for explaining memory, because it can alter the strength between brain cell connections. If this strength is maintained, a memory can be formed.
Long-term potentiation happens when the nerve cells "shed" or speak to one another at a high rate, without increasing the stimulation of neurotransmitters. In a sense, it's like building a relationship with the email sender. Once you have started a dialogue with the sender you are in a better position to communicate more easily and maintain a strong relationship. Just as you can add the sender to your contact list, your brain has created an “enhanced synaptic contact.” But, if you are not speaking, the relationship decreases.
