Appraisal Theory The Effects On Skin Psychology Essay

Appraisal Theory The Effects On Skin Psychology Essay This report aims to replicate a classic finding in biopsychology research which proposed, that increases in task difficulty lead to increases in arousal. As well as to present any individual differences that angle off from this, that possibly could be accounted by the appraisal theory. One hundred and two individuals took part in a task called Speedy Pizzas where they had to deliver successfully a vast quantity of pizzas as the level of difficulty increased. The individuals were represented with a total of 5 levels of difficulty, beginning from level 1 (10 pizzas per minute) to level 5 (50 pizzas per minute). This experiment used a repeated measures design where each individual participated at both levels of task difficulty. The outcome showed that there was a significant increase in GSR as task engagement got more challenging. Although, that the overall GSR test showed increase, individual differences might suggest otherwise. Introduction To begin with, this paper will first examin e some relevant background on the former literature on a classic biopsychology discoveries based on task performance and its association with increase in skin conductance in an attempt to replicate its findings. Afterwards, it will address some individual variations that might have a crucial role in that correlation. A number of researchers over the years have shown that task attainment of individuals is closely knit together with increase in skin conductance. For instance, Kahneman, Trusky et al. (1969 cited in Pecchinenda and Smith 1996) experiment, showed the relationship between skin resistance levels and mental arithmetic task at three layers of difficulty and encountered that skin resistance decreased as difficulty of each level increased. Nonetheless, this connection between them is often distinct, there are cases that the individuals disengage from the task by resigning which is shown in the form of decreasing responses in the GSR levels whilst the task engagement becomes pa rticularly difficult. This occurrence can be placed under the theory of the appraisal model proposed by Smith and Lazarus (1993 cited in Pecchinenda and Smith 1996) that suggested that the amount of each individual’s focusing resources is established by their appraisal of task-solving coping potential. The above theory has been adapted in various studies, one of them was measuring accomplishment in a demanding mental task. (Pecchinenda and Smith 1996) Pecchinenda and Smith’s study wanted to demonstrate the direct association between a cognitive task engagement and the appraisal of each individuals coping potential. Thus, subjects were presented by series of anagrams, that they were called to solve, in various circumstances whilst their GSR was continuously observed. The level of difficulty diverse between each anagram by either having an easy, moderately difficult and extremely difficult anagram as well as the amount of time available that participants had to solve it changed between 30 sec and 120 sec. Results showed that participants coping potential varied between them, since the perception that each subject experienced the situation was different. Paradigm, when an individual appraised their task-solving ability with having a high coping potential approached the task with the attempt to achieve their goal and successfully complete the task. On the contrary, people who appraised the situation as overwhelming and the â€Å"task as virtually impossible† (Pecchinenda and Smith, page 486) had low coping potential and therefore disengaged from the task. Hence, apposite to the skin conductance activity there was a general increase in the GSR levels when the task-solving trials were aligned with the participants’ engagement in the trials. However, this increase dropped dramatically when the anagrams level of difficulty was extremely demanding as a result of the paltry levels of task engagement. An interesting feature about this study th at shouldn’t be obscured was that the correlation between skin conductance activity and task engagement is not absolute. There are other aspects that might intrude and mislead this association. As in that the correlation between GSR and other components such as stress, perception of the circumstance, negative feelings etc resulted as having an impact on the GSR, Nikula (1991 cited in Pecchinenda and Smith 1996). Another related experiment was conducted by Bohlin (1976). Bohlin’s study manipulated the levels of arousal by having participants to response after a number of trials whilst they were in physiological habituation state. She divided the subjects into three groups, the first group were told to relax when listening to a tone, the second one were given arithmetic tasks to solve and the third one a threat of shock was added to the task performance. Results showed that the Shock-threat group had the highest mean in conductance level and the Relax group had the lowes t mean in GSR. Thus, this produces some evidence showing how  increases in task difficulty result in various increases in physiological arousal.
