Breathing Characteristics and Symptoms of Psychological Distress: An Exploratory Study

In this exploratory study of the relationship between characteristics of breathing and 3 common psychological issues (i.e., symptoms of anxiety, alexithymia, and depression), 79 college‐age adults were examined using self‐report, rater observation, and physiological measures. Results indicated significant positive relationships between dysfunctional breath characteristics and symptoms of both anxiety and alexithymia. A significant positive correlation was found between self‐reported symptoms of dysfunctional breathing and symptoms of depression, but no significant relationships existed between symptoms of depression and either rater‐observed breath characteristics or physiological measures.     

Sex,strain, and housing: Variables influencing the effects of prior shock exposure on shock-induced aggression

A series of experiments was conducted to investigate sex, housing conditions, and strain as possible factors influencing the interference effect of prior exposure to shock on shock-induced aggression. In albino subjects, female rats and rats housed in community cages evidenced the greatest suppression in aggression following prior exposure to shock. In addition, ten sessions of prior exposure to shock produced a greater suppression in shock-induced fighting than 20 sessions of prior exposure to shock. The prior shock effect was not obtained with hooded subjects. Responsivity to shock was also investigated to determine whether the prior exposure to shock attenuation of shock-induced fighting was a consequence of reduced activity in response to shock. Responsivity to shock measured with an isometric platform accounted for less than 4% of the variance in shock-induced fighting in the single experiment that obtained a correlation between responsivity and shock-induced aggression.
