Statistical methods are becoming more important in all biological fields of study. Biometry deals with the application of mathematical techniques to the quantitative study of varying characteristics of organisms, populations, species, etc. This book uses examples based on genuine data carefully chosen by the author for their special biological significance. The chapters cover a broad spectrum of topics and bridge the gap between introductory biological statistics and advanced approaches such as multivariate techniques and nonlinear models. A set of statistical tables most frequently used in biometry completes the book.

Mechanisms of Sensory Working Memory: Attention and Performance XXV provides an update on research surrounding the memory processes that are crucial for many facets of cognitive processing and experience, with new coverage of emerging areas of study, including a new understanding of working memory for features of stimuli devoid of verbal, phonological, or long-term memory content, such as memory for simple visual features (e.g., texture or color), simple auditory features (e.g., pitch), or simple tactile features (e.g., vibration frequency), now called sensory memory to distinguish from verbal memory. This contemporary focus on sensory memory is just beginning, and this collection of original contributions provides a foundational reference for the study mechanisms of sensory memory. Students, scholars, and researchers studying memory mechanisms and processes in cognitive neuroscience, cognitive science, neuroscience, and psychology will find this book of great value to their work.

It is well known that the capacity for both simultaneous and rapid sequential information processing is limited. In the past two decades, at least four different approaches for the investigation and explanation of dual-task interference have developed. Surprisingly, these developments have taken place largely independent of each other. For example, working memory theories explain the inability to memorize combinations of data with the existence of modality-specific memory storage. Task switching models attribute switch costs to a combination of task reconfiguration costs and interference between competing task sets. Research with the refractory period paradigm suggests that a second of two responses is slowed because demanding processes such as response decisions defy parallel processing. Finally, attentional blink research shows that limited awareness of the second of two masked visual targets is caused by storage difficulties during the identification of the first target.
The rare attempts at finding bridges between dual-task models attribute the costs to a mixture of shared and unique mechanisms. The ten papers gathered in this issue address questions such as: What is the relationship between working memory storage, retrieval, and cognitive operations? Can control processes account for the attentional blink and the refractory period effect? Are capacity limitations modality specific, and are they triggered by bottom-up or top-down processes? The authors argue that goal adjustments and episodic encoding of events qualify as shared mechanisms underlying dual-task limitations across multiple paradigms.
