SystemsWiki Negative Thinking A CEO calls her staff into the conference room on the eve of the launch of a major new initiative. They file in and take their seats around the table. She calls the meeting to attention and begins, “I have bad news. The project has failed spectacularly. What went wrong?” The team is perplexed: What?! I know it seems strange and maybe even counterproductive to demand that employees think negatively instead of optimistically, but in business circles today, everyone from startups to Fortune 500 companies and the Harvard Business Review are doing this exact exercise. The technique that the CEO above was using was designed by psychologist Gary Klein. Stocklite/Shutterstock In fact, I think more companies need a Chief Dissent Officer, someone to shoot down the bad ideas that our blind spots and naive optimism too often obscure. The practice goes back much further than just psychology though. A writer like Seneca would begin by reviewing or rehearsing his plans, say, to take a trip.

Pour vous fixer les idées, le fait d’ajouter un chrono-contacteur à une cafetière qui mettra cette dernière en fonctionnement à l’heure que vous aurez déterminée à l’avance tout en vous servant de réveil matin n’est en aucun cas une invention mais une innovation. L'invention revêt toujours un caractère technique.

Brain Structures and Their Functions The nervous system is your body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test. The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. What do each of these lobes do? Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli Occipital Lobe- associated with visual processing Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech Note that the cerebral cortex is highly wrinkled.
Pensée latérale Un article de Wikipédia, l'encyclopédie libre. La pensée latérale est un ensemble de techniques théorisées par Edward de Bono, Docteur maltais en médecine et en philosophie, Master en psychologie et physiologie et auteur de plusieurs livres sur la créativité. Cet ensemble de méthodes de résolution de problème consiste à approcher les problèmes sous plusieurs angles au lieu de se concentrer sur une approche unique[1]. Définition et application[modifier | modifier le code] La pensée latérale se définit par opposition à la pensée verticale, qui est la pensée classique, caractérisée par la continuité entre les étapes et la validation pas à pas des hypothèses et de chaque résultat intermédiaire. En pensée verticale, une idée dont l'applicabilité n'est pas validée est rejetée et n'est plus considérée dans la suite du processus. Ces discontinuités peuvent être provoquées de plusieurs manières (Cf. Techniques de pensée latérale[modifier | modifier le code] Exemple 1[modifier | modifier le code]
