In the experiment replicated here, participants hear two sets of digits simultaneously, one in each ear. They tend to report all of the digits from one ear first, and then the digits from the other ear. http://www.psychologypracticals.com/aspx/details.asp?id=16 - 274k APA classification: Attention - Category: Datasets, Cognitive Tutorial Keywords: Hearing, Auditory Localization, Memory, Attention

Attention: Flowers, Warner, and Polansky 1979
This is a variant on the Stroop task, involving numbers rather than colors. Participants are supposed to name the number written on the screen, or the number of words on the screen.

Attention: Gray and Wedderburn 1960
Participants were presented with three-syllable words and three-digit sequences in the same voice, alternating ears. The only cues available, therefore, were meaning and ear-of-arrival. The study found that, where meaning was available, it was used m... http://www.psychologypracticals.com/aspx/details.asp?id=26 - 269k APA classification: Attention - Category: Datasets, Cognitive Tutorial Keywords: Audition, Simultaneous stimuli, Hearing, Division of attention between the ears

Attention: Lupi?z, Mil? Tornay, Madrid, and Tudela 1997
This experiment illustrates inhibition of return (IOR). IOR occurs when a location is cued and then a target appears in it. At that point, participants are slower to notice the target than if it had been in a precued location. http://www.psychologypracticals.com/aspx/details.asp?id=44 - 829k APA classification: Attention - Category: Datasets, Cognitive Tutorial Keywords: Inhibition of return (IOR), Cue target stimulus onset asynchrony, Attention, Reaction time, Stimulus onset, Visual stimulation
Attention: Navon 1977
This experiment asks participants to look for a particular letter (presented either as a large letter composed of other letters, or as the letters that make up the larger letter). For example, if the target were "a", both of these would be permissibl... http://www.psychologypracticals.com/aspx/details.asp?id=50 - 867k APA classification: Attention - Category: Datasets, Cognitive Other Keywords: Processing global and local features, Interference of global vs local visual cues, Auditory discrimation, Visual detection responses, Response latency, Visual discrimination, Visual Field
Attention: Neisser 1964
This experiment compares times to find a "Z" in a column of round letters (O, S, Q) vs. a column of angular letters (K, E, L). It predicts that finding an angular letter in a field of round letters would be easier because the distractors have fewer f... http://www.psychologypracticals.com/aspx/details.asp?id=52 - 200k APA classification: Attention - Category: Datasets, Cognitive Tutorial Keywords: Vision, Scanning process in vision, Search process in vision
Attention: Pashler 1992
This study shows that there is a response selection bottleneck, but that visual attention is not affected by the bottleneck.
The task used was a speeded response to a tone and an unspeeded report of a letter. The tone was often responded to after... http://www.psychologypracticals.com/aspx/details.asp?id=55 - 536k APA classification: Attention - Category: Datasets, Cognitive Tutorial Keywords: Attentional limitations and bottleneck phenomenon, Divided attention, Tasck complexity, Bottleneck effects
Attention: Posner and Mitchell 1967
