Lec 17: Emotion and Judgment/Decesion making

Summary

The lecture examines how emotions influence judgments and decisions, continuing the course’s discussion of interactions between cognition and emotion. Its central point is that current feelings can shape how people interpret situations and choose among options—even when they are not consciously aware of that influence.

Judgment and decision-making

• Judgment means evaluating an object or situation, such as its quality, likelihood, or importance.
• Decision-making means choosing between two or more options.
• These processes are distinct but connected: judgments about available options can shape the final choice.
• Because emotion affects cognitive processes such as attention, perception, and memory, it can also affect judgment and decision-making.

The lecture distinguishes mood-congruent memory from mood-state-dependent memory:

• Mood-congruent memory is the tendency to recall material whose emotional tone matches one’s current mood.
• Mood-state-dependent memory is the improved recall of information when the emotional state at retrieval matches the state in which it was learned. The information itself need not be emotional.

Mood-congruent judgment

Mood-congruent judgment is the tendency to make evaluations that align with one’s current emotional state. The same activity or situation can seem more pleasant when someone feels happy and less pleasant when they feel sad.

The lecture describes several findings:

• Probability judgments: In a study attributed to Johnson and Tversky (1983), participants read either depressing material intended to induce a negative mood or material intended to induce a positive mood. Those in a negative mood tended to overestimate the likelihood of negative events, while those in a positive mood were more optimistic.
• Judgments across domains: Mood can affect evaluations of sensory experiences, other people, oneself, and social situations.
• Brief, unconscious emotional cues: The lecture describes an experiment in which a smiling or disgusted face was briefly shown and then masked by a cartoon character. Participants who saw the disgusted face rated the same character more negatively, while those who saw the smiling face rated it more positively. The emotional cue influenced judgments even though participants were not consciously aware of it. The researcher’s name is unclear in the subtitles.
• Practical applications: Retail environments may use cheerful décor and music to encourage positive feelings. Advertisements often associate products with happy scenes or celebrities who already evoke positive feelings. Political advertising can similarly associate candidates with positive emotions and opponents with negative ones. Such emotional associations may affect choices even without careful evaluation of the product or candidate.

Explanations for emotional influence

1. Somatic marker hypothesis

Antonio Damasio’s somatic marker hypothesis argues that emotion helps guide decisions, particularly in complex or uncertain situations.

• When considering options, the mind estimates possible outcomes and generates emotional responses to them.
• Those responses include bodily and neural changes called somatic markers. They can range from visible changes in facial expression or posture to less visible changes, such as heart rate or hormone levels.
• Somatic markers can guide later choices consciously or unconsciously, helping people decide more quickly than a lengthy cost–benefit analysis would allow.
• Damage to the ventromedial prefrontal cortex can disrupt emotional experience and expression, as well as planning, learning from mistakes, and decision-making.
• The lecture describes a patient with damage in this region who struggled for about half an hour to choose between two possible dates for a doctor’s visit. He listed reasons for and against each option but did not reach a decision, so Damasio ultimately chose for him. The example illustrates the difficulty of relying on slow, deliberate analysis when emotional guidance is impaired.

Emotion is especially relevant when choices involve personal values and preferences, such as deciding which treatment offers the better balance between length and quality of life. These choices cannot always be settled by calculation alone.

The lecture also cautions that extended analysis does not necessarily improve preference-based decisions:

• In a study attributed to Wilson and colleagues (1993), participants chose one of two posters to take home. Some were asked to analyze the reasons for their choice; others chose without that instruction.
• The groups selected different kinds of posters. Three weeks later, participants who had analyzed their reasons reported less satisfaction with their choice.
• One explanation is that verbal analysis can emphasize features that are easy to explain rather than the less easily verbalized factors that initially shaped a preference.
• This is not a recommendation to avoid analysis altogether. Careful comparison remains important for consequential practical decisions, such as choosing health insurance or evaluating candidates. The lecture’s point is that intuition may be useful when subjective preferences and values are central.

2. Affect priming

Affect priming explains how one emotional stimulus can make related emotional information more accessible and thereby influence a later judgment.

1. A stimulus, such as a word, image, or person, elicits an emotional response.
2. That response can activate related emotional memories or associations.
3. The activated information can then influence the evaluation of a subsequent target.

The masked-face and cartoon experiment illustrates this process: the emotional face acted as a prime for the later judgment of the cartoon character.

3. Affect-as-information model

The affect-as-information model, associated with Schwarz and Clore, proposes that people may use their current feelings as information when judging a situation. A person may, in effect, ask, “How do I feel about this?”

• Feeling good can encourage a more positive evaluation; feeling bad can encourage a more negative one.
• Mood can serve as a quick mental shortcut, especially when a situation is complex or people lack the time or energy for detailed analysis.
• The influence is reduced when people recognize that their feelings come from an unrelated source.

The lecture describes a weather and life-satisfaction study:

1. Participants were contacted on either a sunny or gloomy day and asked how satisfied they were with their lives.
2. One group was asked about life satisfaction directly.
3. Another group was first asked about the weather, making the weather—and its possible effect on their feelings—salient.
4. When the weather was not mentioned, participants contacted on sunny days reported greater life satisfaction than those contacted on gloomy days.
5. When participants were prompted to consider the weather first, this difference was reduced. They were less likely to use weather-related feelings to judge their lives.

The finding illustrates that people are less likely to treat a feeling as relevant information when they identify its unrelated source.

4. Affect infusion model

The affect infusion model (AIM) brings together ideas from affect priming and affect-as-information. It describes conditions in which emotion is more or less likely to enter—or “infuse”—cognitive processing and influence judgments.

The lecture presents four judgment strategies:

1. Direct access — low potential for affect infusion

   • A person retrieves an established evaluation quickly and with little effort.
   • Example: rating a familiar singer whose abilities one has evaluated many times.
   • Because the judgment is readily available, there is relatively little need for mood to shape it.

2. Motivational processing — low potential for affect infusion

   • Information is considered in service of a pre-existing goal or motive.
   • Processing is narrow and focused on that goal.
   • Example: an admissions officer may be motivated to favor an applicant from the officer’s hometown. The pre-existing motive may guide the judgment more than the person’s current mood.

3. Heuristic processing — moderate potential for affect infusion

   • A person uses simplified mental shortcuts, often when time or information is limited.
   • This can be efficient but is vulnerable to bias and error.
   • Example: a manager who must quickly screen several résumés may form an evaluation from limited cues. Feelings elicited by those cues can affect the decision.
   • The lecture links this strategy particularly to affect-as-information: people may use their current feeling as a shortcut for evaluating the target.

4. Substantive processing — high potential for affect infusion

   • A person actively searches for, combines, and evaluates information, drawing on existing knowledge to reach a judgment.
   • This is extended and effortful processing, but the model predicts that emotion can influence it strongly.
   • Example: a manager carefully comparing candidates for a critical role may become more critical and risk-focused when in a negative mood, noticing weaknesses that might otherwise receive less weight. A positive mood could lead to a more open or forgiving evaluation.
   • The lecture also connects this strategy to affect priming: emotion can activate related information that enters more extensive reasoning.

Overall lesson

Emotion is not simply an obstacle to rational choice. It can provide rapid guidance, especially in uncertain situations or choices involving personal values. At the same time, mood and emotional associations can bias evaluations—sometimes outside conscious awareness. How much they influence a judgment depends partly on the source of the emotion and on the kind of processing the task requires.
