**Q1: Describe the key ethical principles that underly the licencing of animal research in the United Kingdom** Animal research is a highly **useful** but debated tool in the field of psychology and has been widely used to broaden our knowledge on multiple topics. For example, Harlow's experiments on infant monkeys in the 1950s studied key principles of attachment, and Skinner 1940s studies on operant conditioning as a theory of learning used rats. While the use of animals in psychological research is clearly useful, there are a number of ethical principles that must be abided. The ethical principles underpinning animal research licensing in the United Kingdom are primarily governed by the **Animal Welfare Act 2006** and the **Animals (Scientific Procedures) Act 1986**. These first of these principles is the **Three R's** which aim to minimise animal suffering and enhance scientific validity. **Replacement** advocates for alternatives to animal use wherever possible. **Reduction** encourages researchers to use the minimal number of animals necessary to achieve statistically significant results. Lastly, **Refinement** refers to the improvement of techniques and conditions to minimise pain and distress to the animals. **The necessity principle** mandates that research involving animals must be justified scientifically and ethically, meaning that the potential benefits to scientific knowledge must outweigh the costs to the animals involved. This requires thorough justifications to be submitted as part of the research proposal. Also central to the licensing process is the **ethical review process**, where independent ethical committees assess proposed studies before approval. This process involves critical analysis of the proposed research\'s design, including the application of the Three Rs, ensuring compliance with ethical standards and regulatory requirements. Additionally, there is a growing emphasis on **transparency** in animal research, fostering trust and accountability. Researchers are encouraged to ensure their findings are publicly available and highlight the ethical considerations that guided their work. This responsive approach may counter public scepticism. In conclusion, the ethical principles governing animal research in the UK reflect the **interaction** between scientific advancement and moral responsibility. By adhering to the Three Rs, ensuring rigorous ethical review, and emphasising necessity and transparency, the framework aims to balance the need for scientific experimentation with the ethical obligation to minimise harm. **Q2: Outline the evidence for spatial memory in birds.** Birds exhibit remarkable **spatial memory abilities**, crucial for **survival** in diverse environments. This cognitive capacity is evident in various behaviours, including food caching, navigation during migration, and mate selection (Healy & Hurly, 2004). The first bit of evidence for spatial memory in birds is food caching: Many bird species cache food for later retrieval, demonstrating sophisticated spatial memory. Studies on species like chickadees have shown they can remember the locations of thousands of hidden food items across vast territories (Applegate & Aronov, 2022). These birds exhibit hippocampal enlargement during periods of high food caching, suggesting a neural basis for this spatial memory. Furthermore, experimental manipulations, such as hippocampal lesions, impair food retrieval accuracy (Sherry & Duff, 1996), further supporting the role of this brain region. Migration activity in birds is also evidence for spatial memory. Long-distance migrations require precise navigation, relying heavily on spatial memory. Birds can navigate using a variety of cues, including the Earth\'s magnetic field, and landmarks. Experimental studies have demonstrated that birds can reorient themselves after displacement, indicating a remarkable ability to encode and recall spatial information (Kashetsky et al., 2021). Additionally, mate choice indicates spatial memory. In some species, when choosing a mate, females may assess the quality of the male\'s territory, which requires evaluating its spatial characteristics, such as resource availability and predation risk. Research has consistently implicated the hippocampus in avian spatial memory. Studies utilizing neuroimaging techniques, such as MRI, have revealed that the hippocampus is larger in species with greater reliance on spatial memory, such as food-caching birds (Biegler et al., 2001). Furthermore, studies have demonstrated that the hippocampus exhibits significant neuroplasticity in response to spatial learning demands. This evidence strongly suggests that birds possess sophisticated spatial memory capabilities. This cognitive capacity is essential for various aspects of their lives, including foraging, navigation, and reproduction.
