Training working memory to reduce rumination

Cognitive symptoms of depression, such as rumination, have shown to be associated with deficits in working memory functioning. More precisely, the capacity to expel irrelevant negative information from working memory seems to be affected. Even though these associations have repeatedly been demonstrated, the nature and causal direction of this association is still unclear. Therefore, within an experimental design, we tried to manipulate working memory functioning of participants with heightened rumination scores in two similar experiments (n = 72 and n = 45) using a six day working memory training compared to active and passive control groups. Subsequently the effects on the processing of non-emotional and emotional information in working memory were monitored. In both experiments, performance during the training task significantly increased, but this performance gain did not transfer to the outcome working memory tasks or rumination and depression measures. Possible explanations for the failure to find transfer effects are discussed

Unwanted pursuit behavior after breakup: occurrence, risk factors, and gender differences

This study investigated unwanted pursuit behavior (UPB) perpetration in 631 adult ex-partners. UPB involves the unwanted pursuit of intimacy, a widespread and usually less severe form of stalking. The occurrence and various risk factors of UPB perpetration were examined, accounting for differences between male and female ex-partners and same- and opposite-gender ex-partners. Ex-partners showed on average five to six UPBs after their separation. Male and female and same- and opposite-gender ex-partners displayed an equal number of UPBs. The number of perpetrated UPBs was explained by breakup characteristics (ex-partner initiation of the breakup and rumination or cognitive preoccupation with the ex-partner), relationship characteristics (anxious attachment in the former relationship), and individual perpetrator characteristics (borderline traits and past delinquent behaviors). Rumination was a stronger predictor in female than male ex-partners. Borderline traits and anxious attachment positively predicted UPB perpetration in opposite-gender but not in same-gender ex-partners. Implications of these findings are discussed

The inverse relation between psychopathy and faking good: not response bias but true variance in psychopathic personality

The possibility to assess psychopathy through self-report is debated, amongst others, because psychopathic individuals may deliberately under-report psychopathic features (fake good). Meta-analytic research has shown an inverse relation between faking good and self-reported psychopathy, possibly indicating that faking good lowered psychopathy scores (response bias). Low faking good scores, could, however, also reflect true variance in psychopathic personality to the extent that it reflects a disregard of social conventions. Through a secondary analysis (n = 675), we show that controlling for faking good significantly weakens, rather than strengthens, the associations between psychopathy scores and antisocial behavior (alcohol and drug abuse, indirect aggression, and delinquency). These findings indicate that the inverse relation between faking good and self-reported psychopathy reflects true variance in psychopathy personality (i.e. low social desirability), not a response bias
