Adaptation level theory of tinnitus and neuropsychological theory of tinnitus are extensively used frameworks for understanding emotional and psychological distress among tinnitus sufferers. Objective of the present study was to investigate potential associations between hearing loss, tinnitus, anxiety, depression, and stress. The Tinnitus Handicap Inventory (Newman, Jacobson, & Spitzer, 1996) and the Depression, Anxiety, Stress Scale (Lovibond & Lovibond, 1995)scales were administered to a sample of 110 tinnitus outpatients recruited from Audiology departments of Lahore and Rawalpindi hospitals. Results revealed tinnitus was positively linked with psychological problems. Additionally, it was established that tinnitus is a positive significant predictor for anxiety, stress and depression. The moderation models related to the interactions between psychological problems and hearing loss were negative significant predictors for tinnitus symptoms. Moreover, the comparative analysis between gender differences revealed a significant diversity in the levels of stress, anxiety, and depression. Results also elucidated that patients at initial stages of hearing loss were more prone towards reporting tinnitus symptoms along with emerging psychological problems.

Abstract Living with dementia can adversely affect people's spatial (orientation and navigation) and reality (time, date and place) orientation, which can detrimentally impact on their sense of social inclusion and wellbeing. This is an important challenge to address within United Kingdom (UK) care homes where around 70 per cent of the residents are living with dementia or severe memory problems. Care home managers have some autonomy in decision-making that impacts on the daily functioning of residents and are key in enacting the orientation and navigation agenda within a care home environment. Yet a paucity of literature explores their understanding and experiences of this issue. Contributing to this knowledge gap, our exploratory study examined managers’ current practice of supporting residents with dementia to minimise disorientation and their knowledge of dementia-friendly design principles, guidelines and audit tools. Semi-structured telephone interviews with 12 UK care home managers were conducted. Questions started generally targeting residents’ orientation and navigation abilities, followed by specific questions to draw out strategies used to support residents. Thematic analysis identified three higher-order themes: aligning strategies with needs, intuitive learning and managing within the wider business context. The findings demonstrated that managers perceive dementia to impact on a person's spatial and reality orientation. Consequently, the strategies they chose to adopt were tailored towards alleviating both challenges. However, although managers were aware of some design principles, they frequently relied on intuitive learning and past experiences to inform their choice of interventions, reporting a lack of knowledge and/or time to seek out orientation-specific training and guidance, resulting in a low uptake of guidelines and audit tools in practice. This gap between theory and practice highlights a need for accessible guidelines that integrate strategies with neuropsychological theory, and appropriate training to improve orientation and navigation in care home environments. Managers, staff, business owners, architects and designers all play a key role in implementing orientation guidelines into practice and ensuring dementia-friendly care home environments for residents.

Donald Olding Hebb’s lasting influence in psychology and neuroscience stemslargely from his influential book, The Organization of Behavior (Hebb 1949a) in which he introduced the concepts of synaptic change and cell assemblies to explain the neural events underlying behaviour. Hebb’s work revolutionized psychology by establishing a biological basis for psychological phenomena and expounding a neuropsychological theory which provided the structure for the development of the fields of cognitive and behavioural neuroscience. His ultimate fame could not have been predicted from his performance at Dalhousie University nor from his early career as a teacher. His career as a psychologist began as a night school student in psychology at McGill University in 1928. After completing his MA in psychology at McGill in 1932, he studied with Karl Lashley at the University of Chicago completing his PhD with Lashley at Harvard in 1936. For the next two years he conducted neuropsychological tests on the patientsof Dr. Wilder Penfield at the Montreal Neurological Institute and from 1939 to 1942 was a professor at Queen’s University in Kingston, Ontario. He spent the next five years studying emotionality in chimpanzees at the Yerkes Primate Center in Florida where he began to write The Organization of Behavior. Hebb became a professor of Psychology at McGill University in 1947 and head of his department in 1948 where he completed his book and directed an internationally recognized graduate program in physiological psychology. Elected President of the Canadian Psychological Association in 1952 and the American Psychological Association in 1960 he also became a Fellow of the Royal Societies of Canada and England. Late in his career, he was Vice Dean of Biological Sciences (1964-66) and then Chancellor of McGill University (1970-74). Upon retirement from McGill, he moved back to Nova Scotia and became a professor emeritus at Dalhousie University from 1978 until his death in 1985. During this time he wrote his last book, Essay on Mind (Hebb 1980a). He was inducted into the CanadianMedical Hall of Fame in October 2003.L’influence durable de Donald Olding Hebb dans les domaines de la psychologieet de la neuroscience est en grande partie le résultat de son ouvrage prestigieux The Organization of Behavior (1949) dans lequel il présente les concepts de modification synaptique et de réseau neuronal pour expliquer les phénomènes neuronaux qui sous‑tendent le comportement. M. Hebb a révolutionné le domaine de la psychologie en établissant une base biologique pour des phénomènes psychologiques et en expliquant une théorie neuropsychologique qui a fourni la structure nécessaire au développement des domaines de la neuroscience cognitive et comportementale. Sa renommée n’aurait pu être prédite à partir de sa performance à l’Université Dalhousie ou de son poste d’enseignant au début de sa carrière. Sa carrière dans le domaine de la psychologie a débuté lorsqu’il a commencé à suivre des cours du soir dans le domaine à l’Université McGill en 1928. Après avoir obtenu une maîtrise en psychologie à l’Université McGill en 1932, il a étudié aux côtés de Karl Lashley à l’Université de Chicago pour finalement obtenir un doctorat avec M. Lashley à l’Université Harvard en 1936. Au cours des deux années suivantes, il a effectué des tests neuropsychologiques sur les patients du docteur Wilder Penfield à l’Institut neurologique de Montréal. De 1939 à 1942, il a été professeur à l’Université Queen’s, à Kingston en Ontario. Il a passé les cinq années suivantes à étudier les émotions chez le chimpanzé au Yerkes Primate Center en Floride. C’estau cours de cette période qu’il a commencé à rédiger The Organization of Behavior. M. Hebb a ensuite occupé un poste de professeur de psychologie à l’Université McGill en 1947 et il a été nommé chef du département de psychologie en 1948, poste dans le cadre duquel il a dirigé un programme d’études supérieures de renommée internationale en psychophysiologie. C’est à cette période qu’il a terminé son ouvrage prestigieux. Élu président de la Société canadienne de psychologie en 1952 et de l’American Psychological Association en 1960, il a également été un Membre de la Société royale du Canada et un membre de la Royal Society of England. Vers la fin de sa carrière, il a occupé le poste de vice-doyen des sciences biologiques à l’Université McGill (de 1964 à 1966) puis de chancelier de cette même université (de 1970 à 1974). Au moment de sa retraite de l’Université McGill, M. Hebb est retourné en Nouvelle‑Écosse. Il a été professeur émérite à l’Université Dalhousie de 1978 jusqu’à sa mort en 1985, période durant laquelle il a rédigé son dernier ouvrage Essay on Mind (1980a). Il a été intronisé au Temple de la renommée médicale canadienne en octobre 2003.
