Collision avoidance behaviour in a pair of flying locusts (Locusta migratoria L.)
… and is involved in triggering urgent collision avoidance behaviours. To avoid predators and collision with conspecifics, and to navigate through complex environments, locusts must produce appropriate collision avoidance manoeuvres. Flying locusts have evolved the ability to not only avoid …

Are animals choosing foraging patches according to spatial scaling laws or predator avoidance arguments? : a study on grazing ungulates in Hluhluwe Imfolozi
… into consideration the potential impact predator avoidance behaviour may have on patch choice. Smaller animals are more at risk from predation; thus they have to choose grazing patches that meet their nutritional requirements without exposing themselves to an added risk of predation

Exploring the Role of Implicit Cognition in the Context of Disgust in Individuals With and Without a Diagnosis of Obsessive-Compulsive Disorder (OCD)
… research began with the assessment of relating behaviour pertaining to disgust propensity (initial feeling of disgust) and disgust sensitivity (appraisal of the initial feeling) and sought to determine whether this behaviour was relevant to obsessive-compulsive tendencies and overt avoidance …

Μελέτη της επίδρασης του βαλπροϊκού νατρίου στη διεργασία της ήβης, στη συμπεριφορά ενεργητικής αποφυγής και στις βιολογικές αμίνες του εγκεφάλου, υπό χρόνια και οξεία χορήγηση και από επίδραση stress: Πειραματική εργασία σε επίμυες
… of VPA on the process of puberty, on conditioned avoidance behaviour learning and on brain neurotransmitters of the rats was studied, after chronic and acute administration of the drug and after stress. The brain neurotransmitters NA, DA, DOPAC, (DOPAC/DA), 5-HT, 5HIAA, (5HIAA/5-HT) were measured …

The Interaction Between Learning and Effort-Based Decision-Making: Mechanisms, Structural Brain Correlates, and Links to Neuropsychiatric Symptoms
… behave adaptively, and a key aspect of adaptive behaviour includes how we decide to allocate effort when making decisions. How we learn about our environment is therefore necessarily connected to how we make choices about effort. However, the literature on effort choice has largely neglected this …

A study of the ecology of the Namaqua Sandgrouse and other arid-zone birds
… rate and nest site, nest density, predator-avoidance behaviour, stage of the nesting cycle and season, and degree of residency. Furthermore, the importance of rainfall as a breeding stimulus and its effects on clutch size were investigated for several species. The Namaqua Sandgrouse is an …

Fear of crime in Ulundi
… documented crime related problem. It can lead to avoidance behaviour, for example when normal social activities are curtailed and certain areas are avoided. Lewis and Salem (1986:3) conclude that "fear of crime [has become] as much of a social problem as the crime itself. Fear of crime is …

Scoping of Presence and Impacts of Tyre Wear Particles on Soil Systems
… 2023), were exposed to TWPs and examined their behaviours when contacting to the particles. Then, their bodies were investigated histologically to observe changes in seminal vesicle structures. Concentration of TWP derived elements in earthworm bodies and morphology of ingested TWPs were also …

Cognitive mechanisms underlying emotion regulation
… reappraisal. Antecedent strategies involve avoidance behaviour i. e. avoiding situations in which the emotional response is likely to occur. Recent evidence has now demonstrated, however, that the cognitive and emotional systems are highly interactive and that conscious attention may be …

Detailed item analyses of the Postraumatic Stress Disorder Checklist for DSM-5 (PCL-5): Use in public safety personnel
… symptoms, but did not because none reported avoidance symptoms. The researchers suggested avoidance might be impossible because of paramedic vocational requirements (e.g., required to return to a PPTE scene). The sample was relatively small, included only paramedics, and detailed psychometric …

Non-structural Deterrents and Opportunistic Dispersal in an Invasive Fish: The Role of Among-Individual Variation on Common Carp Movement
… but among-individual variation in dispersal behaviour is rarely considered in aquatic conservation and invasion control. To address this challenge, my thesis applied concepts of behavioural ecology to invasion biology. Using an invasive fish, Common Carp (Cyprinus carpio), as my study …

Using thermal imaging data to explore behaviour in a critically endangered frog species, Craugastor ranoides
Understanding a species behaviour, in particular behavioural thermoregulation, is important as it can indicate how well the species will adapt to changing environments, such as climate change. Ectotherms are particularly vulnerable to the effects of climate warming as they rely on environmental …

The role of the amygdala in dreaming
… threat and escape, as well as for approach and avoidance behaviour, in order to test some of the hypotheses central to Revonsuo’s (2000) threat simulation theory (TST) of dreaming. These analyses produced no significant results. Given that the amygdala is essential to Revonsuo’s (2000) …

An investigation of communication strategy use in reception
… of communication strategy use in the receptive behaviour of second/foreign language learners. The investigation is descriptive in design, and seeks to describe the phenomenon of communication strategies both as a constituent of communicative discourse and as a part of that discourse, in …

Explorations into the behaviour-oriented nature of intelligence : Fuzzy behavioural maps.
This thesis explores the behaviour-oriented nature of intelligence and presents the definition and use of Fuzzy Behavioural Maps (FBMs) as a flexible development framework for providing complex autonomous agent behaviour. This thesis provides a proof-of-concept for simple FBMs, including some …

Causes and consequences of inbreeding in the banded mongoose
… can profoundly shape the evolution of breeding behaviour. Several recent theoretical studies have argued that inbreeding avoidance should not always evolve and that because inbreeding increases the proportion of genes shared amongst relatives it can influence the evolution of altruism. In fact, …

Potential collision risk of harriers Circus spp. with wind turbines during breeding season derived from GPS tracking
… on particular species-specific aspects of flight behaviour that determine the collision risk has remained limited. In this context, GPS telemetry represents a promising but hitherto seldom applied technique. I used an extensive collection of GPS tracking data, including high-resolution flight …

Does facial physiognomy in the context of anoccupational safety and health message predict outcomes?
… that has significance with regard to approach/avoidance behaviour (Oosterhof & Todorov, 2008). These authors found that evaluation of emotionally neutral faces can be explained by judgements of two traits, facial trustworthiness and facial dominance, and that these traits can be related to the …

What lies beneath organisational behaviour : the role of hidden and unconscious processes at work
… theory can add to the study of organisational behaviour, which goes beyond the rational and technological explanations offered by orthodox management perspectives. A key tenet of psychoanalytic theory is that mental processes that are "hidden" and operate at an "unconscious" level can impact …

African penguin (Spheniscus demersus) distribution during the non-breeding season : preparation for, and recovery from, a moulting fast
