Distracting Noise Reduces Task Persistence: A Successful Test of the Strength Model for Self-control
Michael Ouellet, Lionel G. Standing, and Stuart J. McKelvie
Bishop’s University
Using unpredictable noise at a moderate level as a new method to produce ego-depletion, this experiment tested predictions from the strength model of self-control (Baumeister, Vohs, & Tice, 2007), which likens willpower to a muscle that becomes fatigued from use (ego-depletion). Participants (68) were randomized to noise or no-noise groups, and worked on two sets of six anagrams where the sixth was unsolvable. As predicted from the strength model, participants in the noise condition persisted for less time on the unsolvable anagrams than those in the no-noise condition (medium effect size of d = 0.588). There was a general decline in persistence over the two trials, but individual tests showed that the decrease was only significant for the no-noise group. In addition, considering self-control as a subject variable, persistence times were unrelated to self-control trait scores, and the effect of noise on persistence did not differ between people who were higher or lower in trait self-control.

An Investigation of the Incidence of PTSD in Patients Who Have Type II Diabetes or Metabolic Syndrome

The purpose of this archival study is to investigate the incidence of posttraumatic stress disorder (PTSD) in patients who have Type II Diabetes or Metabolic Syndrome and were seen at a local medical office in the last 10 years. Participants were collected through medical records of all the patients 18 and older with Type II diabetes or metabolic syndrome seen by the clinical psychologist at the practice between 2004 and 2012. Medical charts were reviewed to collect demographic data, medical diagnoses, and presence of PTSD. Medical diagnoses were the basis for inclusion in the study and examining the relations between medical diagnosis and PTSD. The hypothesis that the incidence of PTSD is higher in this sample than the general public was supported by a chi-square goodness of fit test. Findings may serve to reveal a bi-directional link between traumatic events, PTSD, and the development of endocrine disorders later in life.
