Value from gestalt: how sequences of competitive actions create advantage for firms in nascent markets
Research on competitive dynamics and hypercompetition has demonstrated the importance of firm competitive actions for disrupting industry positions and gaining competitive advantage. The effects of competitive actions in disequilibrium environments, such as nascent markets, however, have not been examined. In this paper, we argue that under conditions of high ambiguity, firms can gain competitive advantage from the Gestalt properties present in the sequences of their competitive actions. Such properties, we argue, facilitate investor sensemaking and influence their valuations. Drawing on psychological research on pattern perception and holistic information processing, we investigate the effects of four Gestalt properties—simplicity, predictability, grouping, and motif—on investor valuations of new firms competing in the nascent markets that emerged around the commercialization of the Internet in the mid-1990s. We find support for our arguments that the dynamic properties of action sequences provide firms with advantages and that simplicity, grouping, and motif are associated with increases in the market value of high-ambiguity firms, but not of low-ambiguity ones. Our study advances research on competitive advantage by developing both theory and methods for studying how the dynamic, holistic properties of firms' competitive actions contribute to competitive advantage under varying levels of ambiguity.

Connecting the dots: how personal need for structure produces false consumer pattern perceptions
The human tendency to recognize patterns even when none exist is shown to have applications in consumer behavior. The current research demonstrates that as one's personal need for structure (PNS) increases (i.e., requiring predictability and disfavoring uncertainty), false consumer pattern perceptions emerge. Construal level moderates this relationship such that as abstract mindsets (high construal) seek out underlying explanations and enhance, concrete mindsets (low construal) evaluate consumer-related stimuli in terms of its contextual elements and therefore attenuate the effect. Types of consumer patterns are characterized by false expectations about the performance of a cellular phone (study 1), the association of human characteristics toward personal computers (study 2), and the development of beliefs in corporate conspiracy theories (study 3). This research has implications for practitioners and academics as it expands on the literature related to false pattern perceptions by investigating it through the lens of consumer decision-making.

Lacking Control Increases Illusory Pattern Perception
We present six experiments that tested whether lacking control increases illusory pattern perception, which we define as the identification of a coherent and meaningful interrelationship among a set of random or unrelated stimuli. Participants who lacked control were more likely to perceive a variety of illusory patterns, including seeing images in noise, forming illusory correlations in stock market information, perceiving conspiracies, and developing superstitions. Additionally, we demonstrated that increased pattern perception has a motivational basis by measuring the need for structure directly and showing that the causal link between lack of control and illusory pattern perception is reduced by affirming the self. Although these many disparate forms of pattern perception are typically discussed as separate phenomena, the current results suggest that there is a common motive underlying them.

Spatial and temporal codes mediate the tactile perception of natural textures
When we run our fingers over the surface of an object, we acquire information about its microgeometry and material properties. Texture information is widely believed to be conveyed in spatial patterns of activation evoked across one of three populations of cutaneous mechanoreceptive afferents that innervate the fingertips. Here, we record the responses evoked in individual cutaneous afferents in Rhesus macaques as we scan a diverse set of natural textures across their fingertips using a custom-made rotating drum stimulator. We show that a spatial mechanism can only account for the processing of coarse textures. Information about most natural textures, however, is conveyed through precise temporal spiking patterns in afferent responses, driven by high-frequency skin vibrations elicited during scanning. Furthermore, these texture-specific spiking patterns predictably dilate or contract in time with changes in scanning speed; the systematic effect of speed on neuronal activity suggests that it can be reversed to achieve perceptual constancy across speeds. The proposed temporal coding mechanism involves converting the fine spatial structure of the surface into a temporal spiking pattern, shaped in part by the mechanical properties of the skin, and ascribes an additional function to vibration-sensitive mechanoreceptive afferents. This temporal mechanism complements the spatial one and greatly extends the range of tangible textures. We show that a combination of spatial and temporal mechanisms, mediated by all three populations of afferents, accounts for perceptual judgments of texture.

Cortical pattern generation during dexterous movement is input-driven

, but they may also have a pattern-generating role. Here we dissect the contribution of local dynamics and inputs to cortical pattern generation during a prehension task in mice. Perturbing cortex to an aberrant state prevented movement initiation, but after the perturbation was released, cortex either bypassed the normal initial state and immediately generated the pattern that controls reaching or failed to generate this pattern. The difference in these two outcomes was probably a result of external inputs. We directly investigated the role of inputs by inactivating the thalamus; this perturbed cortical activity and disrupted limb kinematics at any stage of the movement. Activation of thalamocortical axon terminals at different frequencies disrupted cortical activity and arm movement in a graded manner. Simultaneous recordings revealed that both thalamic activity and the current state of cortex predicted changes in cortical activity. Thus, the pattern generator for dexterous arm movement is distributed across multiple, strongly interacting brain regions.
The complex patterns of activity in motor cortex that control movements such as reach and grasp are dependent on both upstream neuronal activity in the thalamus and the current state of the cortex.
