Human Motivation One of the most important aspects of a child's psychological growth is the development of self-awareness. According to Thompson, the developmental pathway of the self incorporates several shadings such as the child's growing complexity and ongoing transformation of actual chronicles of self (Dacey, Travers & Lisa, 2009, p.260). He stated that these different aspects of the self continue to grow as social awareness and cognitive maturity result in a child's psychological development through self-concept and self-esteem. The psychological development of a child has been a subject of several studies that have focused on examining the development of humans across the lifespan.

Article Review One:

The first article under review was written by four authors i.e. Amanda Shallcross, Victoria Floerke, Brett Ford, and Iris Mauss and published by the American Psychological Association. This article was published in 2013 following research that was conducted in 2012 on getting better with age. The authors examined the research topic through analyzing the relationship between age, acceptance, and negative effect. After formulating their research hypothesis, the authors carried out the research in a community sample of people between the age of 21 and 73 years. The hypothesis was evaluated through measuring acceptance and several indices of negative effect, which was measured by a discrete emotions approach in which sadness, anger, and anxiety were examined at each time point. The community sample was recruited from Denver, Colorado metro area as part of a wider research project in which the participants received $135. The researchers recruited participants who had undergone a recent stressful life event in order to improve difference in the negative emotions being examined. However, they defined a stressful life event to prospective participants as an event that had huge negative effects on their lives and a discrete starting point within the previous 3 months. Since every participant had experienced a recent stressful life event with significant negative impacts, the relative effect of the event was varied across each of them to an extent that there was a huge distribution of apparent stress across the participants.

Time 1 of data collection involved completion of demographics, trait activation, trait acceptance, and trait negative affect by participants. Time 2 was completion of a laboratory session where negative and physiological reactivity were evaluated while Time 3 involved provision of daily affect reports within 2 weeks through daily diaries. Time 4 was the completion of a follow-up Internet survey that examined trait negative affect. The assessment of acceptance was carried out through the use of Kentucky Inventory of Mindfulness Skills, an acceptance subscale that measures the extent individuals non-judgmentally engage with emotional experiences (Shallcross et. al., 2013, p.737).
The purpose of the research was to determine the link between age and universal negative affect, versus distinct negative emotions. Moreover, the authors sought to identify the commonly misunderstood path that link age to lower negative effect. When carrying out their studies, the researchers recognized that aging involves physical and cognitive declines though it's associated with enhanced emotional well-being, especially lower negative affect. The researchers also tested whether the link between age and lower negative affect would be mediated statistically through acceptance.

The researchers found that age was positively correlated with acceptance while acceptance was negatively linked to every measure of negative affect and affective reactivity though there were different results for sadness reactivity. This is primarily because statistical mediation was not evident for sadness because age and sadness were not linked to each other at each time point and measurement techniques. They also discovered that acceptance statistically arbitrates age-related declines in negative affect. With regards to age and activation, the authors discovered that older adults were not merely less likely to experience every high-activation state though they were less likely to encounter anger and anxiety. The authors discussed several limitations including the inability to rule out cohort effects and inability to conduct advanced modeling based on change over time in every variable due to the nature of the…
