Investigation of the Effects of Impulsivity and Executive Function on a Complex Prospective Memory TaskKellogg, Emily 04 November 2015 (has links)
Prospective memory is colloquially known as “remembering to remember” and refers to forming an intention in the present time to fulfill at some point in the future. It has previously been studied within the context of executive functioning (i.e., purposive and goal directed behavior) and impulsive behaviors (e.g., gambling, risk seeking) within clinical populations. This study sought to further elucidate the relationships of impulsivity and executive functions on prospective memory in a non-clinical population. One hundred and nine undergraduates completed the UPPS-P impulsivity self-report questionnaire, three cognitive tasks measuring components of executive function, (i.e., planning, inhibition, and switching), and a Complex Prospective Memory Task that included Time- and Event-based cues. The UPPS-P and executive function tasks did not significantly predict the Complex Prospective Memory Task. However, executive function was found to be a significant predictor above and beyond that of impulsivity for a component of the Time-based prospective memory task. Implications of the results and future directions are discussed.

Studying Measurement Invariance and Differential Validity of the Short UPPS-P Impulsive Behavior Scale across Racial GroupsMelissa Ann Liu (11632462) 22 November 2021 (has links)
<p>Previous research has identified impulsive personality
traits as significant risk factors for a wide range of risk-taking behavior,
substance use, and clinical problems. Most work has been conducted in primarily
White samples, leaving it unclear whether these patterns generalize to racial
and ethnic minorities, who have higher rates of negative consequences of substance
use behavior. The most widely used assessment of impulsive traits is the UPPS-P
Impulsive Behavior scale, which has strong psychometric properties across
demographic subgroups, such as gender and age; however, data supporting its use
in racial and ethnic minorities is less well-developed. The aims of this study
are to 1) examine the measurement invariance of the UPPS-P Impulsive Behavior
Scale-Short Form (Cyders et al., 2014) across racial minority groups and 2)
determine if impulsive personality traits differentially relate to substance
use outcomes across racial groups. Participants were 1301<sup>
</sup>young adults (ages 18-35, fluent in English), recruited through an online
survey for both college students at a large public university and Mechanical
Turk, a crowdsourcing online platform. Measurement invariance was assessed
using multigroup confirmatory factor analysis. Differential validity was assessed
using a structural equation modeling framework. I established model fit for each
racial group (White group: RMSEA= .067, CFI= .94; Black group: RMSEA= .071, 90% CFI= .952;
Asian American group: RMSEA= .073, CFI=
.94; Hispanic group: RMSEA=.081, CFI=.934). Based on change in CFI/RMSEA
indices, I concluded strong measurement invariance of the Short UPPS-P as a
valid scale of impulsive behavior across racial groups. In the White
group, findings indicated significant relationships between multiple SUPPS-P
traits and alcohol and substance use. In
the Asian American group, positive relationships were found between sensation
and alcohol use (<i>p</i>=.015) and negative urgency and drug use (<i>p</i>=.020).
I found that there were no differences in the relationships between the Short
UPPS-P traits and substance use outcomes across White and the racial and ethnic
groups studied (<i>p</i>’s>.06). </p>

Interoception, Impulsivity and Coping with Stress : An investigation using the Novel Controllability TaskBou Aram, Sinal January 2022 (has links)
Interoception, the signalling, processing, and perceptual representation of the visceral organs, together with trait impulsivity are in the present study examined using the Novel Controllability task (Mancinelli et al., 2021) as individual factors in coping behavior in response to stress. The coping process is conceptualized using the model of regulatory flexibility developed by Bonanno and Burton (2013). The results based on a sample of 39 healthy adults (M = 23,64 years, 22f/17m) do not support the hypothesis that the combined UPPS-P constructs are significantly related to interoception. For the coping process, the results suggest that: Negative Urgency is related to a negative initial appraisal of the stressor context leading to coping rigidity, by limiting the repertoire of strategies and the dynamic function of feedback; Positive Urgency is related to a larger dependency on emotions to guide decision making, motivating a “trial-and-error” coping approach; Sensation Seeking is related with an opposing style of emotion-focused coping where diminished threat perception and reduced sensitivity towards stimulus valence motivate a risk-taking approach, likely to pursue stimulation; Lack of Premeditation, the only facet of impulsivity convincingly related to interoception, is speculated to be associated with a dysregulation of interoceptive afferents facilitating a “here-and-now” attentional and coping focus. Despite lacking full support, the potential involvement of interoception as an internal stressor is discussed as a mediator in impulsive behavior, alongside general methodological issues with measuring interoception.
