Effortful retrieval of semantic memories induces forgetting of related negative and neutral episodic memories.

Retrieval-induced forgetting (RIF) experiments show that the act of retrieving some recently encoded items from a given conceptual category leads to greater forgetting of competing items from that same category. However, RIF studies using emotional stimuli have produced mixed results, perhaps due to the reinstatement of arousal or negative affect during retrieval practice. To induce forgetting of negative episodic memories more indirectly, we examined if retrieving neutral semantic memories leads to RIF of related negative memories.

Subliminal backdoors to forgetting emotional memories.

Weakening negative memories often requires first remembering those events. To bypass this distressing process, Zhu et al. elicited forgetting by subliminally reactivating negative memories near in time to retrieval suppression of unrelated memories.

The effects of assistance dogs on psychosocial health and wellbeing: A systematic literature review.

Beyond the functional tasks that assistance dogs are trained for, there is growing literature describing their benefits on the psychosocial health and wellbeing of their handlers. However, this research is not only widely disparate but, despite its growth, has not been reviewed since 2012. Our objective was to identify, summarize, and methodologically evaluate studies quantifying the psychosocial effects of assistance dogs for individuals with physical disabilities.

Simplifying metal-'ate' chemistry: formation and comprehensive characterisation of a homo-metallic amido lithiate complex.

Addition of TMEDA to lithium allyl-1-naphthylamide in a 1 : 1 ratio afforded the novel amido lithium/lithiate complex, [Li(TMEDA)2][Li{N(1-naph)(CH2CH[double bond, length as m-dash]CH2)}2]. (7)Li NMR and computational calculations indicate this model to be representative of the solution state, with (1)H and (13)C NMR showing a 1,3-sigmatropic rearrangement. [Li{N(1-naph)(CH2CH[double bond, length as m-dash]CH2)}·Et2O]2, and [Li{N(1-naph) (CH2CH[double bond, length as m-dash]CH2)}·PMDETA] , are presented for comparison.
