RST

Selective attention task

The Stroop effect is the delay in reaction time between congruent and incongruent stimuli. Another variant of the classic Stroop effect is the Reverse Stroop effect. It occurs during a pointing task. In a reverse Stroop task, individuals are shown a page with a black square with an incongruent colored word in the middle - for instance, the word "red" written in the color green - with four smaller colored squares in the corners. One square would be colored green, one square would be red, and the two remaining squares would be other colors. Studies show that if the individual is asked to point to the color square of the written color they would present a delay. Thus, incongruently-colored words significantly interfere with pointing to the appropriate square. It is possible to customize the language interface (eg enter color names in your own language). A form for changing application settings is included.

MST

Selective attention task

The Stroop effect is the delay in reaction time between congruent and incongruent stimuli. The Selective Attention Theory suggests that color recognition, as opposed to reading a word, requires more attention. The brain needs to use more attention to recognize a color than to encode a word, so it takes a little longer. Anterior cingulate gyrus, had found increased activated when viewing conflicting stimulus. Source: Stroop effect. Although this application was initially inspired by the classic Stroop task, you need to be aware of the fact that the original Stroop experiment cannot be replicated on a computer. Although this application is manifestly similar to the Stroop task, it is clear that there are large and significant differences between this application and the classic Stroop task (eg here the respondent's answer is motor, not verbal, time is measured differently,..). It is possible to customize the language interface (eg enter color names in your own language). A form for changing application settings is included.

WM11

Find target - movement M-Task

Motion detection plays a very important role in the continuous evolutionary process for species survival. In the past, it was much less researched, compared to the P-pathway, which could be explored in the classical "paper-pencil" way. The M-pathway was not significantly tested until the 20th century when the development of technology finally made it possible to test it. The revolutionary discovery of integrated circuits, and consequently microprocessors, and the development of (cheap) computers, finally enabled a more significant examination of this phenomenon. In real research, it is usually not possible to examine the M-pathway and the P-pathway separately, because they most often act in interaction, and occur in parallel with many other cognitive processes. Despite these problems, this application tries to make a small contribution to further exploration of this interesting and often ignored area. The participant should detect movements and/or changes in the position of target stimuli within different contexts of non-target stimuli.

WinTG

Are you a lecturer or a student? Do you need to prepare examinations for your students? Or maybe you are a researcher who would like to create some exams for practicing or research?
WinTG is a free program for creating exams (test, questionnaire, survey, quiz) on desktop computer.
The WinTG allows you to create text questions that can be of unlimited length. Each question can have an unlimited number of answers. The length of each individual answers in the test is up to 255 characters. Answers to questions in the test are mutually independent, but in case they are the same it can be cloned (copy), which significantly shortens the time of the creation of new  questionnaires (for example Likert scale). Together with the test it is possible to define large number of user-defined data fields that keep the information specific to your exam.
The program can independently calculate the results of the exam. Variables and formulas used to calculate the results of the exam (test, questionnaire, survey, quiz). For this purpose WinTG uses Foreval® (FORmulary EVALuator) – the compiler of the mathematical expressions (formulas) given by strings types with about 50 logical, mathematical and statistical functions. The variables are usually calculated directly from the answers to certain questions in the test, and defines the very fast with a logical "if" conditions using mouse (drag and drop) or in text editor with built-in help (for complex calculations in the test). All variables in the test are mutually independent, but if the variables have the same logical patterns, the formulas can also be cloned which is for example very useful when creating the questionnaire with Likert scale.
With program, it is possible to quick and simple to create a personal user account (username and password) and define the authorization for individual groups of users, define a large number of settings in the test, such as the behavior of the keyboard as well as the appearance of forms with which to conduct examinations and many other properties of the exam: single or multiple choice, skip questions, the timer is turned on or not, evaluation of responses of "free" type (text box), setting the language interface according to own needs, and many other graphic characteristics of the screen.
The program has its own module to save (export) the test results to external files in different file formats. Help file is included with application. Language: Simple English. Access database (survey, questionnaire, test, quiz, exam) created by version 3.1 and above of the WinTG program can be run on asp.net web server using the freeware NetTG web application.

WM3

Mental rotation task

 2D spatial non-verbal working memory task

WM3 is a windows desktop computer program that is used to test the 2D mental rotation. In a 2D mental rotation test, the subject is asked to compare two or more 2D objects (or images) and state if they are the same image or if they are mirror images or if they are completely different images. Commonly, the test will have pairs of images each rotated a specific amount of degrees (e.g. 20°, 75°, 140° or 180°). Some pairs will be the same image rotated, some will be different, and some will be mirrored. Within this program, you can choose from four basic types of experiment (test, task). With these experiments we examine how quickly and accurately a person differs same (rotated) from different (mirror or completely different) images.
The images (stimuli) are created using a mathematical algorithm so that it is quite difficult to verbalize ("nonverbal" stimuli).
You can change a number of settings of the test, which affects the degree of difficulty of the test: a form of stimulus, stimulus presentation time, the length of the delay, the number of correct responses, test duration, the degree of similarity of target and non-target stimuli, the appearance of the screen during the experiment, and more..

Redundancy

Perceptive redundancy task

You've probably noticed that many times you are able to recognize an object in very poor visibility (e.g. fog, twilight,..). This phenomenon has long been used in computer science (e.g. processing and image coding). In recognition of the object in very poor visibility definitely helps a lot previously acquired knowledge and environmental context (for example, driving a car at twilight in Bangladesh we do not expect a polar bear on the road). The empirical fact is that our brain is certainly not required to have 100% of visual information for successful object recognition. The key question is: how little? This application to some extent gives the answer to this question. You'd be surprised how much this number is small.

WM1

Digit span task (visual, auditory and visual-auditory) - classic forward and backward task

Working Memory Computer Test for processing serial (verbal) information in classic forward and backward paradygm in visual and auditory dimension. Auditory tasks are available only in Croatian. You can define your own stimulus. Database support included. In psychology and neuroscience, memory span is the longest list of items that a person can repeat back in correct order immediately after presentation on 50% of all trials. Items may include words, numbers, or letters. Memory span is a common measure of short-term memory. The task is known as digit span when numbers are used. Digit-span task is used to measure working memory's number storage capacity. Participants are presented with a series of digits (e.g., '7, 9, 0') and must immediately repeat them back. If they do this successfully, they are given a longer list (e.g., '6, 2, 4, 9'). The length of the longest list a person can remember is that person's digit span. While the participant is asked to enter the digits in the given order in the forward digit-span task, in the backward digit-span task the participant needs to reverse the order of the numbers.

Backward memory span is a more challenging variation which involves recalling items in reverse order. In a backward digit span task, the procedure is largely the same, except that subjects being tested are asked to recall the digits in backward order (e.g., if presented with the following string of numbers "3 1 4 1 5," the subject would be asked to recall the digits in reverse order; in the case, the correct response would be "5 1 4 1 3").
In a typical test of memory span, a list of random numbers or letters is read out loud or presented on a computer screen at the rate of one per second. The test begins with two to three numbers, increasing until the person commits errors. Recognizable patterns (for example 1, 3, 5, 7) should be avoided. At the end of a sequence, the person being tested is asked to recall the items in order. The average digit span for normal adults without error is seven plus or minus two. However, memory span can be expanded dramatically - in one case to 80 digits - by learning a sophisticated system of recoding rules by which substrings of 5 to 10 digits are translated into one new chunk. The digit span task exercises your verbal working memory. Scientists refer to working memory as the cognitive system that allows the temporary storage and manipulation of information. According to one influential cognitive theory, this system has specialised components, one of which, the 'phonological loop', underlies verbal working memory abilities (Baddeley & Hitch 1974). The phonological loop is comprised of a verbal storage system and a rehearsal system. If you do this task, you may find yourself mentally rehearsing the string of digits as they appeared on screen; this is the rehearsal system in action. It allows the visual inputs to be recoded so that they can enter your short term verbal store and it also refreshes decaying representations (that is, any item that is about to be forgotten).
Verbal working memory is involved in many everyday tasks, from remembering your friend's telephone number while you enter it into your phone, to understanding long and difficult sentences. Think about it; how could you understand a whole sentence if you couldn't remember the words at the beginning long enough to connect with the words at the end! Verbal working memory is also thought to be one of the elements underlying intelligence (or 'IQ'); thus, the digit span task is a common component of many IQ tests, including the widely used WAIS (Wechsler Adult Intelligence Scales). Performance on the digit span task is also closely linked to language learning abilities; improving your verbal memory capacities may therefore help you to master a new language or to expand your vocabulary.

Oculomotor Delayed Response task

This is the first computer program created for Behaviour Brain Research project (was created in 1999 year). It is a sort of like Danny DeVito: it may not be pretty, but it is still functional.

In classic Oculomotor Delayed Response task, subjects fixate on a central stimulus while a target will appear unpredictably in the peripheral space. Subjects must memorize the location of the target, and after a varied delay period, the fixation cue disappears. The disappearance of the fixation point cues the participant to make an eye movement to the location the target appeared. The response is voluntary and utilizes representation of the object in working memory. Source: here
