Examining the effect of spinal cord injury on emotional awareness, expressivity and memory for emotional material.

The prevailing view on the effects of spinal cord injury (SCI) on emotion is that it dampens emotional experience due to a loss of peripheral bodily feedback, with the higher the lesion on the spinal cord the greater the reduction in the intensity of emotional experience. This view persists despite many studies showing an absence of such an emotional impairment in people with SCI. This study specifically aimed to investigate whether total cervical-6 spinal cord transection (i) reduces emotional expressivity and emotional awareness (ii) impairs memory for emotional material. The study contained three groups: 24 patients with SCI, 20 orthopaedic injury control (OIC) patients and 20 young adult controls. A mixed factor design was employed to examine between group and within subject differences. Participants completed the Levels of Emotional Awareness Scale (LEAS), the Berkeley Expressivity Questionnaire (BEQ), and viewed an emotionally arousing slide presentation. Thirty minutes post viewing, participants completed memory tests for the presentation. SCI patients reported greater present levels of emotional expressivity compared with perceived levels prior to their injuries. SCI and OIC groups did not differ on any of the emotional awareness variables. There was also no evidence that SCI leads to impairment in memory for emotional events. This study's findings contradict the mainstream view in the cognitive neuroscience of emotion that SCI dampens emotional experience.

Maternal personality and reproductive ambition in women is associated with salivary testosterone levels.

Previous research has linked testosterone levels with sex-specific personality traits within women. The present study investigates the relation between salivary testosterone levels and specifically maternal personality traits in healthy adult women. Twenty-seven young women completed the Bem Sex Role Inventory (BSRI). Additional questions were asked about maternal personality (importance of having children, self-rated maternal/broodiness), reproductive ambition (ideal number of children, ideal own age at first child) and career orientation (importance of having career). Higher circulating testosterone levels were associated with lower scores on measures of maternal personality and reproductive ambition. There was no relation of career orientation with testosterone. A median split on BSRI masculinity revealed high scorers had higher testosterone levels than low scorers. There was no relation of BSRI femininity with testosterone. Results suggest maternal tendencies may be partly androgen driven.
