Affective context and its uncertainty drive momentary affective experience

Area of Science:

• Psychology
• Cognitive Neuroscience
• Affective Science

Background:

• Affective states fluctuate continuously, influenced by environmental interactions.
• Understanding the dynamic representation of sensory input in experienced affect remains a key research question.

Purpose of the Study:

• To investigate momentary affect as a temporally dependent process.
• To examine how affective impact of stimuli and prior affect shape current emotional experience.
• To determine the influence of affective context uncertainty on this temporal dependency.

Main Methods:

• Participants viewed sequentially presented images and reported their affective experience (valence and arousal).
• Affective experience was modeled using normative image ratings and participants' prior affect.
• Context uncertainty was manipulated by varying the probability of pleasant and unpleasant images.

Main Results:

• Momentary affect (valence, arousal) was influenced by both current image impact and previous affect.
• Increased affective context uncertainty led to heightened negative affect.
• Higher uncertainty amplified the contribution of the most recent image to experienced pleasantness.

Conclusions:

• Momentary affect is a continuous, temporally dependent process.
• Affective experience integrates recent sensory input with the internal state.
• This process is sensitive to the uncertainty within the affective context.
