Attentional Blink Task
Attentional blink (AB) is a phenomenon observed in rapid serial visual presentation. When presented with a sequence of visual stimuli in rapid succession, subjects will often fail to detect a second salient target occurring in succession if it is presented between 200500 ms after the first one.
Career Search is transferable skills analysis software based on the National Occupational Classification Career Handbook. It includes aptitude, interest, education requirements, and physical requirements, among other qualifiers, for over 25,000 job titles. Career Search is used by program planners, labour economists, rehabilitation professionals, and others in the health and social services fields, as well as by insurance companies and litigators.
Functional Mapping Suite
The Functional Mapping Suite includes computer-based cognitive and sensory tasks that activate specific brain structures (e.g., magnocellular and parvocellular layers of the lateral geniculate nucleus), and systems (e.g., cognition, arousal). The tasks themselves can be used to evaluate experimentally induced changes in cognition such as drug-induced cognitive enhancement or impairment, or changes in the speed/accuracy of decision making under varying levels of distraction. The tasks can also be used to evaluate experimentally induced changes in brain function in studies involving medical imaging (i.e., MRI, SPECT) or electrical source analysis (i.e., EEG)
Memory Malingering Task
The Memory Malingering Task is a forced-choice recognition memory task used to evaluate the validity of a patient's effort on behavioral measures of attention, concentration, and memory.
Pain Symptom Ratings, Version 2
The Pain Symptom Ratings provides an independent, reliable, and valid means of predicting treatment compliance and outcome in studies of treatment safety and efficacy. It also allows for unbiased measurement of the legitimacy of self-reported pain severity in forensic settings, and of psychological determinants of pain severity and disability in clinical populations.
Sustained Target Detection Task
The Sustained Target Detection Task is a psychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli. Impairment in this ability is associated impulsivity. Selective attention is the ability to focus on relevant stimuli while ignoring others. This skill is associated with distractibility. The STDT provides the following 4 scores for initiation and inhibition conditions:
Test of Spatial Perseveration
The Test of Spatial Perseveration is a neuropsychological test of "spatial set-shifting", i.e., the ability to display flexibility in spatial learning in the face of changing schedules of reinforcement. The TSP is the spatial equivalent to the Wisconsin Card Sorting Task. The task is believed to activate hippocampal/prefrontal circuits of the non-dominant hemisphere.
Visual Search with Peripheral Visual Distraction Task
The Visual Search with Peripheral Visual Distraction Task is a common visual search task in which the subject searches for a target among a field of distracters. The target varies in discriminability from the field (e.g., finding a B or X among a field of P's). The field varies in density and includes high contrast peripheral visual distraction conditions.
Whissell's Dictionary of Affect in Language
Whissell's Dictionary is a computer program that analyzes the emotional content of language (i.e., text). The program analyzes words along the dimensions of Pleasantness, Activation and Imagery, and also analyzes word frequency (i.e., how common the word is in the English language) and sentence structure (e.g., sentence length, use of exclamation or question marks, etc.).
