Traumatic brain injury and adverse psychological effects: Examining a potential pathway to aggressive offending

Contemporary scholarship has demonstrated an association between traumatic brain injury (TBI) during adolescence and aggressive offending. Research, however, has yet to identify any mechanisms linking TBI to subsequent aggressive offending. Consequently, the current study hypothesized that adverse psychological effects is one such pathway. The current study used the Pathways to Desistance data set (n = 416) to examine the pathway of TBI to aggressive offending through adverse psychological effects. The findings of the structural equation model supported the hypothesized association. Specifically, increased exposure to TBI was indirectly associated with aggressive offending through adverse psychological effects. An additional supplemental analysis illustrated that a direct link between TBI and aggressive offending did not exist for the analytical sample. The findings suggested that the neurological disruptions commonly associated with TBI could result in direct increases in negative psychological outcomes and indirect increases in subsequent negative behavioral outcomes.     

Ekman's basic emotions: Why not love and jealousy?

Paul Ekman's view of the emotions is, we argue, pervasive in psychology and is explicitly shaped to be compatible with evolutionary thinking. Yet, strangely, jealousy and parental love, two emotions that figure prominently in evolutionary psychology, are absent from Ekman's list of the emotions. In this paper we examine why Ekman believes this exclusion is necessary, and what this implies about the limits of his conception of emotion. We propose an alternative way of thinking about emotion that does not exclude jealousy and parental love.
