Psychology: Schachter and Singer Theory

Study Notes

Background of Two-Factor Theory

Emotion theories traditionally focused on physiological responses without cognitive components.
Schachter and Singer proposed that emotion arises from both physiological arousal and cognitive processes.

Psychological Concepts Investigated

Emotional states depend on the interplay between cognitive factors and physiological states.
Situations with cognitive awareness of danger but no physiological arousal suggest that the absence of physiological responses means no emotional experience occurs.

Research Aim

To test if cognitive influences affect emotional experiences during unexplainable physiological arousal.
To determine if appropriate emotion labeling is consistent in the presence of an explanation for physiological states.
To observe if physiological responses can evoke emotions regardless of cognitive context.

Hypotheses

Arousal without explanation will lead participants to label feelings based on available cognitions, affecting emotional labeling.
If participants have proper explanations for their arousal, they are less likely to interpret their feelings based on external stimuli.
Absence of arousal will result in cognitive processes being disregarded, leading to no emotional experience.

Experiment Type

Conducted as a laboratory experiment.

Experimental Design

Utilized an independent measures design.

Sample Characteristics

Comprised 184-185 male college students.

Sampling Technique

Employed an opportunity sampling method.

Independent Variables Operationalization

Different treatment groups based on information provided about epinephrine injections: informed, misinformed, ignorant, and placebo.

Dependent Variables Operationalization

Emotional states assessed through controlled observations and self-reported questionnaires.

Control Measures

All participants received injections and followed the same procedural guidelines, ensuring consistency in observations by trained observers.

Data Types Collected

Quantitative data collected through structured observation of participant behavior.
Qualitative data from self-reported questionnaires with a 5-point emotional scale.

Experimental Procedure

Participants misled about the study's focus, injected with Suproxin (epinephrine or placebo), and placed with a confederate displaying either euphoric or angry behavior.
Observations captured emotional responses influenced by the confederate's mood.

Key Results

Physiological responses significantly higher in epinephrine conditions compared to placebo.
Participants without proper explanations (Epi Ign and Epi Mis) exhibited more euphoric behaviors and emotional susceptibility.
Euphoria self-reports varied, revealing lower euphoria in informed participants compared to misinformed ones.

Conclusions

Findings supported the two-factor theory by demonstrating the role of physiological and cognitive interactions in labeling emotions.
All three main propositions of the theory received support from the experimental results.

Generalizability Concerns

Sample comprised entirely of male psychology students, potentially limiting broader applicability of findings.

Reliability Issues

Complexity of the study led to challenges in replication, later studies failing to reproduce the results.

Validity Considerations

Ecological validity questioned as induced emotional experiences differed from real-life scenarios.
Participants' initial mood states were not assessed, potentially influencing reactions to situational stimuli.

Ethical Considerations

Deception involved due to the use of confederates and misleading study purpose.
Participants' vulnerability to demand characteristics due to their academic context.

Other Evaluation Aspects

Controlled environment for administering injections and procedures.
Utilized ambiguous and playful materials to elicit reactions in participants.

Issues and Debates

Strengths in control through random allocation of participants and robust standardization.
Discussions about the complex relationship of emotions beyond initial two-factor theory predictions.
