Dunkel, C., Kim, J., & Papini, D. (2012). The general factor of psychosocial development and its relation to the general factor of personality and life history strategy. Personality and Individual Differences, 52(2), 202-206. doi:10.1016/j.paid.2011.10.016. In this article, the authors’ relate a person’s psychosocial development to general factors of personality (Dunkel, Kim, & Papini, 2011, p. 1). The ultimate goal of the study was to test two hypotheses. The first hypothesis is that psychosocial stages form from a GFPD (General Factor of Psychosocial Development), with the LH strategy, and GFD combined a “Super-K” value would emerge from it (Dunkel, et al., 2011, p.4). The authors’ discuss the general factors …show more content…
The purpose of the study was to explore the relationship between personality and self-esteem (Erdle, et. al., 2009, p. 343). The authors also used the “Big-Five Personality” types in order to determine the relationship between self-esteem and personality. The participants completed an online questionnaire. This was measured using the Big Five Inventory. Self-esteem was measured by using a Single Item Self-Esteem Scale (Erdle, et. al, 2009, p. 344). The participants of the study included 628,640 people, who ranged from ages 9 to 90 (Erdle, et. al., 2009, p. 344). The results from the experiment formed were rather interesting. The study showed a correlation between self-esteem and the Big Five Factors (Erdle, et, al, 2009, p. 344). This was interesting because of the two sharing common traits. This correlation is important because it shows the relation between personality and self-esteem. However, there were problems with the experiment. The problem involves having a poor model for general factors (Erdle, et. al, 2009, p. 344). It is a problem because the authors’ did not take into account adding self-esteem to the GFP table. The evidence showed that things such as Stability and Plasticity have a strong influence on personality. However, the study had limitations. The …show more content…
The authors’ wanted to determine the relationship between personality traits, the cerebral cortex, and how they are affected under different motivation conditions (Sato, et al., 2012, p. 1). However, motivation and personality are not necessarily displayed outright. The authors’ tested the relationships through the NEO Personality Inventory-Revised and the multichannel near-infrared spectroscopy; the authors’ wanted to determine three motivations, which were control, monetary reward, and goal-oriented motivations (Sato, et al., 2012, p. 1). They wanted to use the motivations in order to determine if rewards had a correlation with personality. The authors involved 36 males, who ranged from 19-29 years of age and had a history with medicine (Sato, et al., 2012, p. 2). The experiment resulted in correlations between goal-oriented motivations, cerebral cortex activity, and personality traits (Sato, et al., 2012, p. 1). This is important to the authors’ study because these traits help form a person’s personality. According to the authors’, personality involves certain patterns of thinking, feeling, and behavior (p. 1). The authors used tools such as the NIRS, in order to examine brain imaging as well as certain personality measurements in this particular journal. In order to determine motivations, the authors also used the Edinburgh Handedness Inventory Scale. With the monetary test, the participants were rewarded 100 yen
