Acquisition and retention of an active avoidance response to intense white noise: Kamin effect
… investigate the acquisition and retention of an active avoidance response in rats to intense white noise. The results of Experiment 1 indicated that rats can acquire an active avoidance response to white noise. In Experiment 2 retention of avoidance performance was shown to be a U-shaped function …

Neural substrates of avoidance behavior: The afferent limb
During avoidance conditioning, the rabbit sitting in a large activity wheel was presented with two tones. One tone the positive conditional stimulus (CS+), predicted a mild foot-shock, the other tone (CS$-$) did not. The rabbit could learn to avoid the footshock by locomoting in the running wheel. …

The ostracode Cypridopsis vidua : physiological response due to thermal stress.
… per mg biomass with decreasing size of organism. Active avoidance of 30 and 35C temperatures was observed.

A Novel Experimental Method for Measuring Proactive and Reactive Responses to Threat and an Examination of Their Personality and Neural Correlates
… dissertation is to characterize goal directed proactive behavioral responses to threat as well as reactive responses to threat exposure, and to identify the neural and personality correlates of individual differences in these responses. Three specific studies are reported wherein participants …

Generality of learning differences in mice genetically selected for differences in brain weight
… enriched environment and tested on open field, active avoidance, water maze, operant discrimination, and passive avoidance tasks. Mice from one foundation stock yielded mice with high and low brain weight. The control groups for this selection were composed of one group of medium brain weight …

The Association between Obesity, Cognition, and Visual Function
… male and female ob/ob mice performed worse on an active avoidance paradigm, indicating frontal cortical impairment. The ob/ob mice also performed worse on vision-associated tests. The results from this study suggested that obesity impairs cognitive and visual function in a sex-dependent manner. In …

PTSD symptom clusters : the relationship with types of traumas and cognitive ability
… Finally the theme that the PTSD symptoms Active avoidance and Negative alteration in cognition and mood would have positive association on cognitive ability emerged in Memory and Working memory. These findings support the necessity to explore types of traumas as well as PTSD symptom …

Health-Related Quality of Life and Future Care Planning Among Older Adults: Exploring the Role of Hope as a Moderator
… about care preferences, concrete planning, and active avoidance). In addition, data were collected on five HRQoL domains (physical function, physical role function, emotional role function, social function, and bodily pain) and trait hope. Moderated multiple regression was used to test the …

Intrusive Memories, Coping And Outcome In Depression: Towards A Traumatic Processing Model?
… of avoidant coping, specifically of Cognitive Avoidance, is significantly predictive of the maintenance of disturbing intrusions. This finding is interpreted in the context of traumatic processing models. Finally, predictions based on the conceptualisation of dissociation as an avoidant coping …

Analisi dell’espressione della fosfoERK quale strumento di indagine per la caratterizzazione della sensibilità alle sostanze d’abuso in linee di ratti geneticamente selezionati
… Among those, the Roman high (RHA)- and low (RLA)-avoidance rats are selectively bred for rapid vs poor acquisition of active avoidance, respectively, and differ markedly in emotional reactivity, coping style, and behavioral and neurochemical responses to a number of drugs of abuse such as …

Characterization of the Roman lines/strains of rats as a genetic model of psychiatric disorders: a behavioral and brain dialysis study
… is represented by the Roman high- (RHA) and low-avoidance (RLA) lines/strains of rats, which are psychogenetically selected for, respectively, rapid versus extremely poor acquisition of active avoidance in a shuttle box. A large body of evidence indicates that a major reason for their divergent …

Physiological and behavioral drivers of angling vulnerability in freshwater sportfish
… to evolutionary pressure favoring passive and reactive behavior in exploited systems. In chapter 3, I examined the role of metabolic phenotype in driving angling vulnerability in bluegill. Similar methods were used to assess metabolic rate as in chapter 2, with an additional examination of …
