We report a laboratory experiment that investigates the impact of observational learning and visual information display on bubble formation in asset markets with inexperienced and experienced traders. We first vary whether the continuously-updated transaction prices are displayed in a column of text or in a graphical display (with time on the X-axis and price on the Y-axis). Second, to explore ...

This study aims to examine and compare the mechanisms through which social learning processes influence knowledge contribution behavior of lurkers contributors in open innovation communities (OICs). Based on theory stimulus–organism–response (SOR) framework, this developed a model formation mechanism from environmental stimuli (observational learning, reinforcement learning), organi...

The main algorithms for causal structure learning are PC (for observational ...

The dorsal striatum plays a key role in the learning and expression of instrumental reward associations that are acquired through direct experience. However, not all learning about instrumental actions require direct experience. Instead, humans and other animals are also capable of acquiring instrumental actions by observing the experiences of others. In this study, we investigated the extent t...

BACKGROUND Previous research has shown that observation can be effective for learning in various domains, for example, argumentative writing and mathematics. The question in this paper is whether observational learning can also be beneficial when learning to perform creative tasks in visual and verbal arts. AIMS We hypothesized that observation has a positive effect on performance, process, a...

Serotonin (5-HT) modulates emotional and cognitive functions such as fear conditioning (FC) and decision making. This study investigated the effects of a functional polymorphism in the regulatory region (5-HTTLPR) of the human 5-HT transporter (5-HTT) gene on observational FC, risk taking and susceptibility to framing in decision making under uncertainty, as well as multidimensional anxiety and...

Consumers’ purchase decisions can be influenced by others’ opinions, i.e., word-of-mouth (WOM), and/or others’ actions, i.e., observational learning. While information technologies are creating increasing opportunities for firms to facilitate/manage these two types of social interaction, researchers so far have encountered difficulty in disentangling their competing effects and have provided li...

This study examines the effects of different uncertainty types on interorganizational imitation in firm exit decisions. We draw upon herding models to conceptualize exit decisions as being based on a firm’s private information, which the firm updates with information inferred from observing the actions of others. We posit that different types of uncertainty differentially affect this observatio...
