Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

43.5K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Self-Regulation01:25

Self-Regulation

226
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Stimulants01:29

Stimulants

848
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

191
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Human Genetics01:28

Human Genetics

1.5K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Summary

Electronic gaming machine (EGM) customers struggle to accurately recall or predict their gambling expenditure. Most players lack awareness of their spending, highlighting a need for product and environmental changes to support informed decision-making.

Area of Science:

  • Behavioral Economics
  • Gambling Research
  • Consumer Psychology

Background:

  • Informed decision-making regarding gambling expenditure requires understanding affordability and potential returns.
  • Electronic gaming machines (EGMs) possess structural features that may hinder informed choices, such as disguised losses and credit displays.
  • Accurate recall and prediction of past and future gambling spending are crucial for financial awareness.

Purpose of the Study:

  • To investigate Australian electronic gaming machine (EGM) customers' understanding of their recent and future EGM spending.
  • To assess the accuracy of EGM customers' recall and prediction of their gambling expenditure (net outcome, wins, total spend).
  • To identify factors influencing the accuracy of gambling expenditure understanding.

Main Methods:

  • Survey responses from 187 Australian EGM customers were linked to their venue account data.
  • Participants' recall and prediction accuracy for 30-day expenditure (net outcome, wins, spend) were analyzed.
  • Statistical analysis explored the relationship between personality traits (impulsivity, risk-taking) and expenditure accuracy.

Main Results:

  • Few customers accurately recalled (5.5%) or predicted (17.4%) their net gambling outcome within a 10% margin.
  • Accuracy in recalling/predicting wins and total spend was also low across participants.
  • Accurate reporting was mainly limited to individuals who did not gamble during the reported period.
  • Higher impulsivity and risk-taking correlated with less accurate predictions of net outcome and spend, respectively.
  • Participants often overestimated net results but underestimated wins, suggesting winnings were re-gambled without awareness.

Conclusions:

  • EGM customers demonstrate a significant lack of understanding regarding their gambling expenditure.
  • Current EGM product design and environments may impede informed decision-making.
  • Recommendations include modifications to EGMs and their surrounding environment to promote financial awareness and informed choices for players.
