Pneumothorax-I01:26

Pneumothorax-I

588
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Area of Science:

  • Psychology
  • Neuroscience
  • Human Behavior

Background:

  • Existing research on emotional tears predominantly uses posed, static stimuli.
  • A gap exists in resources for studying spontaneous, dynamic emotional expressions, particularly tears.

Purpose of the Study:

  • Introduce the Portsmouth Dynamic Spontaneous Tears Database (PDSTD).
  • Provide a validated, freely accessible resource for researchers studying sadness and tears.
  • Investigate the impact of spontaneous tears on the perception of sadness.

Main Methods:

  • Collected video recordings of 24 female encoders experiencing neutral and sad films.
  • Obtained norming data from 91 observers rating emotional expressions across three phases (neutral, pre-sadness, sadness).
  • Utilized general linear mixed modelling (GLMM) for data analysis.

Main Results:

  • Confirmed successful elicitation of sadness in the stimuli.
  • Demonstrated a significant 'tear effect': spontaneous tears substantially increase perceived sadness.
  • Validated 72 recordings for emotional expression, valence, arousal, and genuineness.

Conclusions:

  • The PDSTD is the first openly available database of spontaneously elicited dynamic tears and sadness.
  • The findings highlight the significant role of spontaneous tears in modulating perceived sadness.
  • This resource will advance research into the complexities of human emotional expression.
