Towards Empowerment: Narrative Study of Counselling Psychology Trainees and How They Make Sense of Their Personal and Professional Development in the Context of Their Past Experiences

The discipline of counselling psychology continues to grow and change in response to social, economic and political pressures. It has been argued that its quest for a coherent and distinct identity, which emphasises the possibility of the coexistence of multiple approaches, creates an inherently uncertain and dilemmatic training environment that may hinder the development of trainees’ professional identities. In order to gain a deeper understanding of the issue at hand, the aim was to explore how final year trainees and newly qualified counselling psychologists constructed and made sense of their emerging professional identities and what experiences, past and present, they drew upon in the context of their training to shape those identities. Applying narrative inquiry to analyse eight open-ended interviews, eight preliminary themes were originally identified in participants’ narratives, which with further refinements lead to stories of struggle and marginalisation, growth and discovery, and power and resilience. Participants’ stories of struggle and marginalisation emerged in reference to early family dynamics and stressful life experiences, which seemed to also foster a strong identification with the counselling psychology profession, while stories of growth and discovery focused on the importance of having supportive figures, who helped to instill a sense of security and create an atmosphere of openness. It was in this learning environment that participants felt it was possible to develop a more resilient, empowered professional self, which allowed them to shed an earlier sense of struggle and vulnerability. However, where more of an emphasis was placed on power and resilience, there seemed to be less room for participants to express other feelings that came into conflict with their preferred sense of professional self. While there seems to be a need for a ‘safer’ climate, in which trainees could voice and acknowledge anxieties, vulnerabilities and limitations, addressing concerns around power and vulnerability that may be contributing to the silencing of particular voices and identities may be equally important if trainees are to develop coherent and distinct counselling psychologist identities.

A Spiking Neural Network Model of the Medial Superior Olive using Spike Timing Dependent Plasticity for Sound Localisation

Sound localization can be defined as the ability to identify the position of an input sound source and is considered a powerful aspect of mammalian perception. For low frequency sounds, i.e., in the range 270 Hz-1.5 KHz, the mammalian auditory pathway achieves this by extracting the Interaural Time Difference between sound signals being received by the left and right ear. This processing is performed in a region of the brain known as the Medial Superior Olive (MSO). This paper presents a Spiking Neural Network (SNN) based model of the MSO. The network model is trained using the Spike Timing Dependent Plasticity learning rule using experimentally observed Head Related Transfer Function data in an adult domestic cat. The results presented demonstrate how the proposed SNN model is able to perform sound localization with an accuracy of 91.82% when an error tolerance of +/-10 degrees is used. For angular resolutions down to 2.5 degrees , it will be demonstrated how software based simulations of the model incur significant computation times. The paper thus also addresses preliminary implementation on a Field Programmable Gate Array based hardware platform to accelerate system performance.
