The impact of retrieval practice on analogical-problem-solving performance was investigated using a complex, educationally relevant task. Participants studied statistical hypothesis testing scenario and practiced recalling the material or repeatedly it. then completed final test either 5 minutes 1 week later involving novel hypothesis-testing that shared an intermediate procedural strategy superficial structural similarity with study but differed at specific procedure level. When given after...
Research methods and statistics are an indispensable subject in the undergraduate psychology curriculum, but there challenges associated with engaging students it, such as making learning durable. Here we hypothesized that retrieval-based promotes long-term retention of statistical knowledge psychology. Participants either studied educational material four consecutive periods, or it just once practiced retrieving information subsequent three then took a final test through which their was...
A common assumption in attention theories is that prioritizes search items based on their similarity to the target. Here, we tested this and found it wanting. Observers searched through displays containing candidates (distractors cannot be confidently differentiated from target by peripheral vision) lures can be). Candidates had high or low Search were either candidate-homogeneous (all of same similarity) candidate-heterogeneous (equal numbers each similarity). Response times equivalent...
To access the content of digital texts efficiently, it is necessary to provide more sophisticated than keyword based searching. Genescene provides biomedical researchers with research findings and background relations automatically extracted from text experimental data. These a detailed overview information available. The were evaluated by qualified are precise. A qualitative ongoing evaluation current online interface indicates that this method search literature useful efficient
In the laboratory, visual search is often studied using uniform backgrounds. This contrasts with in daily life, where potential items appear against more complex present study, we examined effects of background complexity on a parallel under conditions objects are easily segregated from background. Target-distractor similarity was sufficiently low such that could unfold parallel, as indexed by reaction times increase logarithmically set size. The results indicate when backgrounds relatively...
In visual search, the more similar target to distractors, less efficient search; search. Very little has been done understand how similarity arises in multi-dimensional stimuli. previous work, we have studied bi-dimensional dissimilarity when stimuli differ along two feature dimensions search (color and shape; shape texture; color texture). Here, report our first evaluation of complexity differs from distractors three (color, Experiments 1-3, tested people’s efficiency differed a set...
Abstract Prior research has shown that the arousal and valence dimensions of emotional images distort perceived duration those images. Further, these time distortions are eliminated when observers feel in control over events experiment. The present study had two goals. first goal was to replicate effect on perception, using a design where manipulated within subjects. second evaluate whether experimental manipulation related feelings experienced daily life, as assessed by Desire for Control...
When the spatial configuration of a search display is presented repeatedly, response times to finding target within that are shorter compared completely novel configurations, even though observers do not have explicit recognition repetition. This phenomenon known as Contextual Cueing and selective attention thought be necessary for effect. Previous research has suggested repetition context unattended items does appear improve performance; only attended does. It been proposed this occurs...

Contrary to most models of visual search, recent work from our lab showed that variability in efficient search is meaningful and systematic. Reaction times (RTs), which reflect stage one processing times, increase logarithmically with set size, indicating an exhaustive the scene, even presence easily visible singleton target. This modulated by distractor-target similarity. The functional viewing field (FVF) - region surrounding fixation useful information can be extracted has been shown...
Recently, Buetti, Cronin, Madison, Wang, and Lleras (2016) found that reaction times increase logarithmically as a function of set size in fixed-target efficient search tasks. The authors proposed these logarithmic functions arise because stage-one is parallel, unlimited capacity, exhaustive process. In stage-one, evidence accumulated at each location the display to determine whether likely contain target or not. Once reaches threshold, it can be confidently rejected unlikely target. These...
Parallel processing in efficient search tasks involves a rejection of non-target items via process evidence accumulation. This accumulation results logarithmic increase response times as function set size. The slope this indexes the rate accumulation; greater target-item similarity, slower rate, steeper slope. Although almost all visual real world against backgrounds, thus far has only been examined without backgrounds. Here, we effect background information tasks. In Experiment 1, stimuli...
