Algorithms and circuits for motor control and learning in the songbird
… teeth, we learn many of our motor skills through trial and error. Many biologically based trial and error learning models depend on a teaching signal from dopamine neurons. Dopamine neurons increase their firing rates to signal outcomes that are better than expected and decrease their firing rates …

Models for project management
… perform work essentially through operations and projects. The characteristics of projects makes them extremely difficult to manage: their non repetitive nature discards the trial and error learning, while their short life span is particularly unforgiving to misjudgments. Some authors have …

EFFECTS OF RESPONSE FREQUENCY CONSTRAINTS ON LEARNING IN A NON-STATIONARY MULTI-ARMED BANDIT TASK
An n-armed bandit task was used to investigate the trade-off between exploratory (choosing lesser-known options) and exploitive (choosing options with the greatest probability of reinforcement) human choice in a trial-and-error learning problem. In Experiment 1 a different probability of …

Resources and capabilities in high-tech enterpreneurship : a study of two generations of Chinese startups
By examining the origin and growth dynamics of two generations of high-tech startups in China's information technology sectors, this study presents empirical research on how Chinese technology startup companies, despite their lack of many of the basic elements that are usually necessary for a …

Search Strategies in Holistic Design Problems
… design, small household appliance design, and automotive design. Design, as a creative activity, employs a search process because solutions cannot be found by optimisation procedures from input parameters. Holistic designs are characterised by the overall design performance arising from …

Response Guided Errorless Learning with Normal Elderly
… investigates the use of response guidance for errorless learning of a perceptual motor task in normal elderly. It provides normative data for a study with stroke patients using this technique for cognitive rehabilitation. While errorless learning has been shown to be more effective on most …

Sociality, social learning and individual differences in rooks, jackdaws and Eurasian jays
… opportunities to learn from one another. Social learning provides individuals with a relatively cheap and quick alternative to individual learning. This thesis investigated social learning in three corvid species: gregarious rooks (Corvus frugilegus) and jackdaws (Corvus monedula) and …

The role of basal ganglia-forebrain circuitry in the vocal learning of songbirds
… sub-cortical structure in the human brain and are implicated in numerous human diseases. In songbirds, as in mammals, basal ganglia-forebrain circuits are necessary for the learning and production of complex motor behaviors; however, the precise role of this circuitry remains unknown. This …

From brains to bears. understanding brain size evolution: causes, costs and benefits
Developmental and energetic costs result in brains being expensive organs to grow and maintain, yet large brains have evolved in many mammalian species. The adaptive value of increased brain size has come under scrutiny over the past few decades and despite considerable research effort, much …

Variability in Singing and in Song in the Zebra Finch
… is a defining feature of the oscine song learning process, reflected in song and in the neural pathways involved in song learning. For the zebra finch, juveniles learning to sing typically exhibit a high degree of vocal variability, and this variability appears to be driven by a key brain …

Experimental investigations of cognitive abilities in a socially complex mammal, the spotted hyena (Crocuta crocuta)
… share many mental traits with other animals, and that the differences in cognitive abilities between humans and other animals are a matter of degree, not kind. Currently, the leading theory to explain the evolution of intelligence is the Social Intelligence Hypothesis (SIH), which posits that …

Studies of the White Pelican in South Dakota: Reproductive Biology of Wild Populations and Effects of Polychlorinated Biphenyls and DDT on the Behavior of Penned Birds
The learning behavior of penned white pelicans (Pelecanus erythrorhynchos) was studies 2 August to 5 October 1972 using a swimming pool – Y-maze apparatus in an operant conditioning experiment. The experiment consisted of three consecutive phases: trial-and-error learning, extinction, and …
