Summary
Negative emotional priming increases preference for immediate rewards, driven by altered time perception, not response inhibition. This impacts inter-temporal choice decisions.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Decision-Making Science
Background:
- Inconsistent findings exist regarding emotion's influence on inter-temporal choice (IC).
- Understanding the mechanisms behind emotional effects on decision-making is crucial.
Purpose of the Study:
- To investigate the impact of temporary emotional priming on inter-temporal choice.
- To explore the underlying mechanisms, specifically time perception and response inhibition.
Main Methods:
- Participants underwent temporary emotional priming using affective pictures.
- Inter-temporal choice, time reproduction, and Go/NoGo tasks were administered.
- Performance metrics included reward choices, reaction times, and error rates.
Main Results:
- Negative emotional priming significantly increased the choice of smaller-but-sooner rewards (SS%).
- Negative priming led to shorter reaction times in time reproduction, indicating time overestimation.
- Time overestimation was negatively correlated with IC performance; Go/NoGo task performance remained unaffected.
Conclusions:
- Myopic decisions under negative emotions are linked to altered time perception.
- Response inhibition is not the primary mechanism mediating emotional effects on IC.
- Emotional states significantly modulate economic decision-making through perceptual changes.

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.

01:25Factors Affecting Perception
3.2K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

01:37Reason and Intuition
7.7K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

01:29The Influence of Cognition on Affect
308
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...

01:29Dark Triad and Person Perception
454
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...
