This study used a computer-based emotional word-recognition task to assess the emotional processing styles of repressive–defensive youth. A hypothesis was tested proposing that adolescent repressive– defensive coping style is associated with rapid engagement and disengagement of emotional stimuli (negative and positive). Data were collected on a male adolescent sample enrolled in a juvenile div...
Cues that signal the possibility of receiving an electric shock reliably induce defensive activation. To determine whether cues can also easily reverse defensive reactions, a threat reversal paradigm was developed in which a cue signaling threat of shock reversed its meaning across the course of the study. This allowed us to contrast defensive reactions to threat cues that became safe cues, wit...
Executive summary. Conventional wisdom maintains that investors can improve their portfolio's performance during bad times by shifting their equity exposure defensively toward less-cyclical, lower-beta sectors. This paper investigates the strengths and weaknesses of defensive equity investing by focusing on the historical performance of defensive sectors during two periods: U.S. equity bear mar...
Gray and McNaughton [Gray JA, McNaughton N. The neuropsychology of anxiety. Oxford: Oxford University Press; 2000] predict that fear is associated with orientation away from threat whereas anxiety is associated with orientation towards threat; this first dimension of 'defensive direction' is independent of a second dimension of 'defensive intensity'. Defensive reactions were measured using a th...
Catalysis of NAD(+)-dependent ADP-ribosylation of proteins, nucleic acids, or small molecules has evolved in at least three structurally unrelated superfamilies of enzymes, namely ADP-ribosyltransferase (ART), the Sirtuins, and probably TM1506. Of these, the ART superfamily is the most diverse in terms of structure, active site residues, and targets that they modify. The primary diversification...
The transcriptome of drought-stressed grapevine leaves was analyzed using RNA-sequencing (RNA-seq) technology and compared. In this experiment, 12,451 differentially expressed genes (DEGs) were recorded in response to drought by RNA-seq, which includes 7,983 up-regulated and 4,468 down-regulated transcripts, proposing that drought stress has induced/repressed many genes. Biological and physiolo...
Animals promote their survival by avoiding rapidly approaching objects that indicate threats. In mice, looming-evoked defensive responses are triggered by the superior colliculus (SC) which receives direct retinal inputs. However, the specific neural circuits that begin in the retina and mediate this important behaviour remain unclear. Here we identify a subset of retinal ganglion cells (RGCs) ...
