1 Introduction During the instance-specific macro learning experiments , we faced a problem in which there was no significant difference between the perfect model and the other models / macro sets. I thought initially that learning in general is not useful. But then I realized that this problem was caused partially by the way I collect data. The test examples were so easy to capture any significant difference in performance between the models. So, we need to make the test instances harder to solve in general.
Laboratories are environments that the scientist can control and indeed manipulate the various independent variables however they wish. They can calculate the effects of a single independent variable while removing the possibility that any other factors are affecting the dependent variable they are studying. b) Assess the reason why experiments are rarely used in sociology. (12 marks) Even though experiments appear to be extremely useful in proving something to be true, or to simply find a lot more about a certain subject, in sociology they are not as useful and reliable. They frequently incur many ethical or practical problems and are therefore not used as often as the results they show are very questionable.
Additionally, positive illusions can help stave off discomfort and maintain healthy levels of self-esteem, at least in the short term.

This form of positive illusion is so dangerous because it is so easily taken from the individual to the group level: My group is right because we see things the way they are, and every other group that disagrees with us is biased and blinded by their religion, ideology, or self-interest. Without naïve realism, Haidt argues, there would be no war, conflict, or violence. Overall, it is safe to say that there are both pros and cons to positive illusions.
The mean values compare the averages of the conditions and the contexts in which the image was presented before, after or never. The ‘mean values comparing techniques’ indicate that re-typing is the worst for memory retention while practice recall was slightly higher than re-reading. The ‘mean values comparing contexts’ show that having an image before produced the highest correctly recalled in participants while participants in the image after and no image conditions had similar correctly recalled. Context before group (Condition 1, 2, 3) had a higher mean value (p < 0.05) than Context after group (Conditions 4, 5, 6). While re-reading as a technique has more correctly recalled sentences rather than re-typing (p<0.05).
The data support the primacy effect pop music results supported the hypothesis that pop music leads to a happier mood. The results from this data support from previous literature research such as the pop category. The results could also interpret as support for (Hargreaves, 1999). People make their music preferences based on the emotional state they are in (Hargreaves, 1999). The analysis revealed that pop music scored higher than students who had rock or classical.
In the early primacy portion of the serial position effect, there was a direct positive relationship between the frequency of rehearsal and the probability of recall. That is to say, the primacy effect was entirely dependent on rehearsal. The early items can be rehearsed more, and thus recalled better. The recency effect, was viewed as recall from short-term memory, which is why they were recalled so well even if being rehearsed so little (Ashcraft, 2010). The improved recall for the words at the ... ... middle of paper ... ...able conditions; while people will usually prefer options presented earlier for undesirable conditions (Epley, 2009).
Internal validity Experimental designs are desirable for internal validity because random assignment eliminates the possibility of a spurious causal relationship and selection bias (Shadish, et al., 2002). Moreover, random assignment removes other types of threats to internal validity such as history, maturation, and attrition because any difference between treatment and control groups occurs by change in randomly assigned experiments (Alferes, 2012; Shadish, et al., 2002).

Longitudinal designs also have the same benefits from the questionnaire survey methods, but they are less cost-effective because follow-up observations are required. For the same reason, cross-sectional designs are cost-effective and provide efficient management for human resources.
This link was not as evident, as both Experiment 2 and 3 did not highlight a clear decrease in percentage of cheaters within the time prime. A control prime would have created more clarity within the results of these experiments. Self-reflection within the study was the main form of reasoning to explain the overall link between time, money and morality. Due to well conducted experiments in relation to self-reflection, Gino and Mogilner’s (2013) study showed a convincing and very plausible link between these. The positive effects of self-reflection have also been recognised by numerous other studies (Colineau & Paris, 2010; Plonerb & Regner, 2013).
Eventually, each theme area was researched for sub-themes and the data re-coded to these sub-themes.

On the contrary, particular events may be overstated because of political advantage or personal preference. For this reason quantitative research’s transferability is better than that of the qualitative research, considering that there are no statistical tests for significance in qualitative work.
In the essay “Graduation Inflation”, by Amy Dickinson, she explains how celebrating too often can diminish the actual purpose of celebrating. When we are addicted to celebrating every little thing, it can be problematic as excessive rewards and commendatory certificates can dull out the celebrating experience. Consequently, when a big event does occur, it might seem less significant. Over-commending reduces the value of celebrating events that are more worthy; for example, cases such as winning the league championship might seem less important when celebrating becomes frequent. However, when people get rewarded, especially children, they receive a feeling of greatness where their accomplishments feel extraordinary which induces their motivation and determinism.
