External-memory search trees with fast insertions
… and theoretical contributions regarding external-memory dynamic search trees with fast insertions. The first contribution is the implementation of the buffered repository B-tree, a data structure that provably outperforms B-trees for updates at the cost of a constant factor decrease in query …

A comparison of visual and memory search processes within a single task
The present information processing research provided a comparison of visual search and memory search processes with respect to search rates and search strategies. An innovative paradigm was evaluated which varied search type (i.e., visual or memory) randomly between trials of a single choice …

Working Memory, Search, And Signal Detection: Implications For Interactive Voice Response System Menu Design
Many researchers and speech user interface practitioners assert that interactive voice response (IVR) menus must be relatively short due to constraints of the human memory system. These individuals commonly cite Miller's (1956) paper to support their claims. The current paper argues that these …

The Error-Related Negativity: Evidence for a Neural Mechanism for Error-Related Processing
… a sentence verification task, a Sternberg memory search task, and two letter discrimination tasks. In all these experiments, a negative-going deflection (the error-related negativity, or ERN) in the event-related brain potential began around the time of error onset and peaked about 100 msec …

Intraserial repetition effects upon levels of cognitive processing
… repetition were tested using a probeless memory search task. Reaction time was facilitated in Experiments II and III only if the task involved alphabetical comparisons suggesting that repetition affects a comparison stage. The results of Experiment III revealed that the location of an item …

Contributions of Source-Constrained Search and Late Monitoring to Recall Accuracy
… control comprises processes occurring at memory search and post-retrieval. There is a large body of research concerning post-retrieval monitoring processes; however, less is known about how memory search is constrained and what factors affect this process.Chapter 2 developed and tested a …

Processing Phenomena and the Dissociation Between Subjective and Objective Workload Measures (Cognition, Automaticity, Verbal Reports)
… performance were investigated. A Sternberg memory search task was utilized. Sternberg task configurations varied in the automaticity of performance, stimulus presentation rate, discernability of stimuli, and the value of good performance. Automaticity in Sternberg task performance was …

The affective and cognitive context of self-reported measures of subjective well-being
Researchers attempting to understand the experience of subjective well-being have relied heavily on self-report measurement methodology. Recent research focused on such methodology has demonstrated that a number of factors, such as the current mood of the respondent and the cognitive and social …

The development of skill : the coefficient of variation as an index of skill acquisition
Previous research has found that extensive practice usually leads to faster more stable reaction times (RTs). The goal of this study was to distinguish practice effects which are due to a speed-up (where reduced RTs and correspondingly reduced variability in RT indicate that the task is being …

Cognitive functioning, cardiovascular activity, and state affect in men with and without a parental history of hypertension
… on Block Design, Visual Span, and Sternberg Memory Search Task when compared to PH- individuals. Also, PH+ participants reported higher anxiety and irritability during Block Design than PH- participants. PH+ participants performed more poorly on Block Design even after controlling for group …

A comparison of process and memory-based theories of automaticity
Process and memory-based theories of automaticity are contrasted by manipulating the information contained in primary memory. Process-based theories predict that performance will be modulated by the information contained in primary memory, while memory-based theories predict that performance which …

HE-MT6D: A Network Security Processor with Hardware Engine for Moving Target IPv6 Defense (MT6D) over 1 Gbps IEEE 802.3 Ethernet
… language, a configurable and a parallelized memory search through tag-based Hybrid Content Addressable Memory (HCAM) L1 write-through cache, full RTL Network Time Protocol version 4 hardware module, and a modular crypto engine. HE-MT6D supports multiple nodes and provides 1,025% throughput …

Dual task performance and antihistimine use
Research has shown that many antihistamines produce sedative effects as well as impair psychomotor performance. Performance testing of antihistamines, however, has not produced reliable evidence that there are behavioral effects at therapeutic dose levels. Therefore, the objective of this research …

The reminiscence bump in autobiographical memory: An investigation of the life script hypothesis
<p>Researchers have consistently found that older adults report a higher percentage of autobiographical memories for experiences that occurred between ages 15 and 30 compared to any other period of life. This reminiscence bump is evident for memories involving positive emotions but not for memories …

Spontaneous Recognition Memory Measured by Performance in a Memory Stroop Paradigm
Studies of recognition memory have generally involved tests in which the participant's memory is directly questioned. There are occasions, however, in which memory is more spontaneous in nature: e.g., recognizing an acquaintance out of context). The current studies investigated spontaneous …

Messung der Leistungsfähigkeit mit der AGARD-STRES-Battery nach partiellem Schlafentzug im Vergleich zu Alkohol und Hypoxie

Foraging memory: Retrieving words from one and from two semantic categories
Traditionally applied to an animal's search for food, the concept of foraging has been extended to include the search for information in such places as the Internet and libraries (Pirotti & Card, 1999). The premise behind the research reported here is that memory searching can also be construed as …

Performance Monitoring: Error Detection and the Error-Related Negativity in Choice-Related Time Tasks
… in this thesis, subjects performed a visual search, a memory search and an Eriksen flankers task. The error-related negativity (ERN) was smaller with high search loads, with non-automatized stimulus-response mappings, with extended wakefulness, and with reduced stimulus contrast. These data …

Essays on attention and creative thought
… Lopez) begins with a puzzle that arises from research on mind wandering: since during mind wandering we plausibly prioritize the information relevant to the concurrent tasks less, why does mind wandering sometimes improve rather than impair concurrent task performance? I resolve the puzzle by …
