Contingency awareness and its effects on fear-potentiated startle and extinction [PDF]

, 2019
Fear-potentiated startle is defined as an increase in the magnitude of the startle reflex in the presence of a stimulus that has been paired with an aversive stimulus or event.

No Time-Dependent Effects of Psychosocial Stress on Fear Contextualization and Generalization: A Randomized-Controlled Study With Healthy Participants

Chronic Stress, 2019
The formation of context-dependent fear memories (fear contextualization) can aid the recognition of danger in new, similar, situations. Overgeneralization of fear is often seen as hallmark of anxiety and trauma-related disorders.

Impact of heat exposure during immobilization‐induced de‐training and re‐training on aerobic capacity and haemoglobin mass

Experimental Physiology, EarlyView.
Abstract The aim of this work was to assess the effect of heat exposure on cardiorespiratory and haematological responses during de‐training and re‐training. Nineteen men (33.8 ± 2.7 years; 182 ± 5.7 cm, 84.4 ± 9.3 kg) completed 4 weeks of pre‐training followed by heat exposure (HEAT; n = 9) or control (CON; n = 10).

Fear conditioning of SCR but not the startle reflex requires conscious discrimination of threat and safety

Frontiers in Behavioral Neuroscience, 2014
There is conflicting evidence as to whether awareness is required for conditioning of the skin conductance response (SCR). Recently, Schultz and Helmstetter (2010) reported SCR conditioning in contingency unaware participants by using difficult to ...

From Prevention to Healthy Longevity: Evaluating the Multi‐Systemic Effects of Physical Activity and Lifestyle Behaviours in Women

Reproductive, Female and Child Health, Volume 5, Issue 4, December 2026.
ABSTRACT Purpose Despite spending more on healthcare than any other high‐income nation, the United States faces comparatively poor life expectancy outcomes, primarily due to non‐compliance with preventable and modifiable lifestyle behaviours. This review evaluates the multi‐systemic benefits of physical activity, exercise, diet, weight management and ...

Interoceptive fear learning to mild breathlessness as a laboratory model for unexpected panic attacks

Frontiers in Psychology, 2015
Fear learning is thought to play an important role in panic disorder. Benign interoceptive sensations can become predictors (conditioned stimuli - CSs) of massive fear when experienced in the context of an initial panic attack (unconditioned stimulus ...

Acute Reactive Strength Responses and Peak Power–Performance Relationships After Flywheel Calf Raises in National‐Level Track‐and‐Field Athletes: A Randomized Crossover Trial

European Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT This study examined reactive strength responses to flywheel eccentric calf raises performed under three inertial loads and the associations between peak power and post‐intervention reactive strength. Thirty‐seven national‐level male track‐and‐field athletes completed three randomized crossover trials (≥ 48 h apart), each involving 3 × 8 calf ...

Long-term memory for pavlovian fear conditioning requires dopamine in the nucleus accumbens and basolateral amygdala.

PLoS ONE, 2010
The neurotransmitter dopamine (DA) is essential for learning in a pavlovian fear conditioning paradigm known as fear-potentiated startle (FPS). Mice lacking the ability to synthesize DA fail to learn the association between the conditioned stimulus and ...

Successful management of upper airway obstruction using an external manual removal technique in a dog: Implications for pre‐hospital and hospital emergent interventions and post‐procedural care

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract A 2‐year‐old, female, spayed German shepherd dog presented to the University of Illinois Small Animal Emergency Room for an upper airway obstruction caused by a ball. The event was observed by the owner and presentation was immediate. The patient was stridorous and cyanotic with a markedly increased respiratory rate. An external manual removal

Individual differences in fear potentiated startle in behaviorally inhibited children [PDF]

Developmental Psychobiology, 2013
AbstractBehavioral inhibition (BI) is a temperament characterized during early childhood by increased fearfulness to novelty, social reticence to unfamiliar peers, and heightened risk for the development of anxiety. Heightened startle responses to safety cues have been found among behaviorally inhibited adolescents who have an anxiety disorder ...
