Popis: Abstract How people experience nature influences their attitudes and actions towards it. Having had a negative encounter with an animal may facilitate avoidance and freezing responses which may encourage negative feelings towards it and the environment in which it is found. Animals associated with fear, such as snakes, are often the victims of hunting and killing, possibly in part due to an overperception of their inherent danger. Past research has shown that fear affects approach–avoidance response at both the preparatory and executive stages of movement. However, the way one reacts to different threats may also depend on its proximity and how fearful one is of that specific threat. We employed a mouse‐tracking paradigm where participants (N = 40) categorized pictures of threatening and non‐threatening animals (snakes and butterflies respectively). The picture could appear at the middle, top or bottom of the screen. Participants initiated the movement from the centre of the screen and the category labels appeared on the top of the screen. Participants therefore had to either move towards the picture on the top or move away from the picture (presented centrally or at the bottom). Participants were split into fearful and non‐fearful groups based on self‐report snake fear. Non‐fearful participants were generally slower when a threat was present. But, in the fearful group, we found longer movement initiation times for central threats and shorter initiation times for off‐centre threats (compared to neutral targets). Fearful participants were also slower to initiate movement when moving away from the threat, but faster when moving towards it (compared to neutral targets). The slower start and execution may be due to the lack of active planning and/or may imply the presence of a passive temporary freezing response. Strong negative emotions towards nature and animals serve as crucial factors both in animal phobias and anti‐animal behaviours (i.e. the purposeful decimation of certain species). Understanding the action dynamics of approach–avoid behaviours in response to threatening animals may help to inform both the prevention and treatment of phobias, and relatedly, the promotion of conservationist endeavours.
