Exercise-Induced Hypoalgesia Is Not Influenced by Physical Activity Type and Amount.

Unlabelled: Physical activity (PA), especially vigorous-intensity PA, has been shown to be related to pain sensitivity. The relationship among PA levels and PA types on endogenous pain inhibition after exercise, termed exercise-induced hypoalgesia (EIH), remains unclear.

Purpose: This studied examined the EIH response to pressure stimuli among college-age women of differing activity levels.

Smoking and membership in a fraternity or sorority: a systematic review of the literature.

Objective: Fraternity and sorority members have higher rates of smoking than other college students. This systematic review examines studies that included fraternity/sorority membership in their investigation of smoking behaviors.

Participants/methods: Studies identified in MEDLINE, PsychInfo, JSTOR, CINAHL, ERIC, and Google Scholar published between 2003 and 2013 were included if they included fraternity and/or sorority membership, were written in English, published in a peer-reviewed journal, and had smoking as an outcome variable.

Emotional stimuli and context moderate effects of nicotine on specific but not global affects.

The authors tested the hypothesis that the effects of nicotine on affect are moderated by the presence or absence of emotionally positive and negative stimuli and by attentional choice to avoid attending to emotionally negative stimuli. Thirty-two habitual smokers were assigned to tasks allowing attentional freedom to look back and forth at 2 simultaneously presented pictures, whereas another 32 habitual smokers viewed single pictures without attentional choice. Picture contents in both tasks were 1 of 4 combinations: emotionally negative + neutral, negative + positive, positive + neutral, or neutral + neutral.
