Timing, working memory and expectancy: a review of interference studies

Claudette Fortin, Richard Schweickert
2016 Current Opinion in Behavioral Sciences  
We underscore the similarity between this pattern and results observed in research on complex span, a measure of working memory capacity.  ...  In studies reviewed, consistent interference between timing in the range of seconds and concurrent memory search was found, but no interference with visual search, switching or activation from long-term  ...  Dzhafarov from the U.

Directly Evaluating the Cognitive Impact of Search User Interfaces: a Two-Pronged Approach with fNIRS

Horia A. Maior, Matthew Pike, Max L. Wilson, Sarah C. Sharples
2013 European Workshop on Human-Computer Interaction and Information Retrieval  
This paper describes our two pronged approach focusing on a) moving fNIRS research beyond simple psychological tests towards actual interactive IR tasks and b) evaluating real search user interfaces.  ...  Recent research has pointed towards further understanding the cognitive processes involved in interactive information retrieval, with most papers using secondary measures of cognition to do so.  ...  Using a secondary measure, the Stroop task, Gwizdka [10] mapped varying levels of workload at multiple stages of search.  ...

Visual search for category sets: Tradeoffs between exploration and memory

M. M. Kibbe, E. Kowler
2011 Journal of Vision  
Limitations of working memory force a reliance on motor exploration to retrieve forgotten features of the visual array.  ...  As the complexity of the category rule increased, search favored exploration, with more visits and revisits needed to find the set.  ...  The cognitive demands of the search task were manipulated by varying the complexity of the rule that defined the set of target objects.  ...

The effect of cognitive abilities on information search for tasks of varying levels of complexity

Kathy Brennan, Diane Kelly, Jaime Arguello
2014 Proceedings of the 5th Information Interaction in Context Symposium on - IIiX '14  
We describe a study in which we explore how people's cognitive abilities affect their search behaviors and perceptions of workload while conducting search tasks with different levels of complexity.  ...  To evaluate the relationship between cognitive ability, task complexity and workload, we conducted three separate mixed factor ANOVAs corresponding to each of the abilities.  ...  Associative Memory While working (short-term) memory is of central importance in search tasks, intermediate memory comes into play as search tasks become more complex.  ...

Searchers switch tactics under increased mental load

Jacek Gwizdka
2013 Proceedings of the American Society for Information Science and Technology  
Effects of mental demands on searchers were examined by controlling tasks complexity and by assessing searchers' working memory span (WM). The searchers were divided into low and high WM group.  ...  Low-WM searchers performed about the same number of searches and switched their tactic by visiting significantly fewer search results.  ...  In our study, we controlled search user interface, mental demands imposed by a task (by varying its level of complexity) and we assessed participants' mental capacity by testing their working memory span  ...

On the utility of P3 amplitude as a measure of processing capacity

ALBERT KOK
2001 Psychophysiology  
by the joint operation of attention and working memory.  ...  The major factor that prompts this conclusion is that the two principal task variables that have been used to manipulate capacity allocation, namely task difficulty and task emphasis, have opposite effects  ...  Consistent with the study of Hoffman, Kramer further showed that effects of memory load on P3 amplitude were much smaller during the consistent mapping than during the varied mapping condition.  ...

The Role of Working Memory Representations in the Control of Attention

G. F. Woodman, S. J. Luck, J. D. Schall
2007 Cerebral Cortex  
To test this hypothesis, we asked subjects to perform a visual search task during the delay interval of a visual working memory task.  ...  Thus, a search template is stored in visual working memory only when the target varies from trial to trial.  ...  Notes We would like to thank Gordon Logan, Andrew Rossi, Shaun Vecera, and Edward Vogel for valuable discussions regarding this work and the anonymous reviewers for their comments.  ...

The ticking time bomb: Using eye-tracking methodology to capture attentional processing during gradual time constraints

Ana M. Franco-Watkins, Matthew E. Davis, Joseph G. Johnson
2016 Attention, Perception & Psychophysics  
We examined how different experiences of time constraints affected decision strategies on a probabilistic inference task and whether individual differences in working memory accounted for complex strategy  ...  Our results indicate that although participants change search strategies during the most restricted times, the occurrence of the shift in strategies depends both on how the constraints are applied as well  ...  The research was supported in part by grant SES-0851990 from the National Science Foundation.  ...

The Development of Nonverbal Working Memory and Executive Control Processes in Adolescents

Monica Luciana, Heather M. Conklin, Catalina J. Hooper, Rebecca S. Yarger
2005 Child Development  
To test this hypothesis, adolescents (9 to 20 years old) completed nonverbal working memory tasks with varying levels of executive demands.  ...  Consistent with these events, prefrontal functions that demand high levels of executive control may mature later than those that require working memory but decreased control.  ...  Search complexity varied in this study from searches of three locations to searches of eight locations.  ...
