Subject profiling is a method used to analyze intraindividual differences, that is to say variability in terms of research participants' profiles. Research participants have different characteristics in terms of subject matter knowledge, interests, personality, and strategic processing. Their behaviour is likely to be affected by cognitive and noncognitive factors which configure differently within individuals.

Subject profiling is often undertaken by means of tests or questionnaires intended to assess various aspects of a person. For example, these tests can be used to measure intelligence, or outline core personality traits. Many tests, especially those designed to identify personality traits, ask the test-taker to answer multiple-choice questions in relation to typical behaviours. Other types of tests, such as those intended to measure intelligence, ask the test-taker to answer test questions correctly.

In translation and interpreting process research, there is growing interest in how research participants’ individual differences influence task performance. Distinct and informative participant profiles can be obtained with a number of different aptitude and personality instruments. The tests listed below are just some of the available tests that can be used to characterize participants’ mental abilities, personality traits and language skills.


Quantitative methods collect and analyse quantitative data on variables, that is to say, on characteristics that can have different values. They are focused on quantity, and aim to predict, control, describe, confirm and test hypotheses. A number of instruments and techniques are available to collect quantitative data. Among them, one of the most representative and commonly used is the survey, which is used to obtain, systematically, information regarding the variables bearing on a research study.

There are various types of tools for data collection within the framework of a survey, including interviews or tests, but the most widespread and used technique within the research community is the questionnaire. This needs to be well-structured but the participation of the researcher in its administration is less required, especially when data are collected online.

Online questionnaires are an effective alternative to traditional paper surveys administered in person or by mail, and its advantages include the speed with which data can be collected, its cost-effectiveness, and the confidential and anonymous treatment of responses.


An eye tracker is a device which registers eye movements. The most common type is the video-based eye tracking system, which typically uses infrared light to create a corneal reflection that is recorded by a camera. The eye movement data allow the experimenter to calculate fixation count and duration, saccades, regressions and pupillary movements. For translation experiments, remote eye tracking systems are preferred as they allow the participant free head movement and visual access to the keyboard. Depending on the equipment, remote eye tracking systems register eye movements with a frequency of between 120 Hz and 1000 Hz, and they are accurate to 0.5 of a degree, which corresponds to up to 1 cm of inaccuracy.


This category includes Electroencephalography (EEG) and Electrocardiography (ECG).


The investigation of coherent electric activity in the brain has opened new possibilities to our knowledge on human cognition. Electroencephalography (EEG) is the recording of electrical activity along the scalp. Different EEG techniques are used to investigate cognitive processing:

EEG Coherence is the oscillatory coupling between two channels, occurring with several oscillations, in a narrow frequency band, for a given period of time. EEG Coherence measures electric signal correlation between regions and over trials. Two types of coherent activity can be detected in oscillatory signals picked up from two brain or scalp areas: Synchrony and Asynchrony. EEG Coherence is used to quantify the existence of coherent brain activity differences between conditions.

Event-Related Potentials (ERPs) are very small voltages generated in the brain structures in response to stimuli, and thus perceived to be the direct result of cognitive processes. ERPs are time-locked, i.e. a point in time is marked when a stimulus occurs, and averaged on a large number of trials in order to cancel out noise in the data. In the domain of language processing, cognitive ERPs such as N400 and P600 are related with information processing.  The N400, a peak in the electrical activity measured 400 milliseconds (ms) after stimulus, is usually associated to the expectancy of a given word to end a sentence. The P600, generated 600 ms after stimulus, is typically elicited in the case of grammatical errors and syntactic anomalies.


An ECG is used to measure the rate and regularity of heartbeats. ECGs performed for research purposes serve to establish a connection between neurovegetative activity (level of alertness, emotion, physical implication) and cognitive processing. Performing information processing tasks, such as e.g. sentence generation, has been found to lead to accelerated heart rate, corresponding to a high level of vegetative activity.


Keystroke logging, or keylogging, is the action of recording (or logging) the keys struck on a keyboard.


Speech recognition (SR) is the process of converting spoken input into written text using a computer application. SR allows the user to generate text without the use of a computer keyboard, and it can potentially reduce the amount of time used to produce a text or a translation. Users typically need to train their SR system in order to improve the recognisability of the spoken input and thus the quality of the written output.


Screen recording software captures all on-screen activity that transpires during the course of translation in video (usually avi or flash) format. Such activity includes the utilization of CAT tools, online information retrieval, patterns in text generation, revisions, and overall translation workflow. Most screen recording applications also capture keystroke and mouse click data. Screen recording videos can be played in real time, or at speeds of up to 16 times the original. Additional electronic recording device features, such as pause, rewind, and fast-forward, are also standard.

 A major advantage of screen recording as a research tool is its relative preservation of ecological validity. Translators are not required to do anything they would otherwise not do while translating in their natural environments and the software can be readily installed on any computer. The software runs in the background during task completion in an unobtrusive manner.

To date, screen recording has been utilized as a method for researching such phenomena as translator style, problem-solving, and revision tendencies.


Remote monitoring software brings the possibility of seeing what users are doing and typing in real-time from any web-browser. It documents from words typed, to web search and programs used. Some of its remote access and monitoring features are: remote installation, configuration and removal, anytime access, centralized tracking, real-time activity viewing, invisibility, logging of keystroke, application usage and website activity, recording of all online searches as well as access to all files and documents opened from within the operating system. It is also easy to use.

Caution: Although monitoring software is legal, it must only be used with the consent of the subjects under study so that it is not confused with a spyware.


Tagging texts is the most frequent form of corpus annotation. It usually refers to Part-of-Speech (PoS) tagging, i.e. the grammatical annotation of language data which can be retrieved by search engines developed by computational linguists. Tagged texts contain identification fields (tags) usually in XML format. These tagged segments are usually enclosed between the symbols < and /> which refer to the specific part of a text assigned to a particular PoS. There are several taggers available in the web, some of which can be downloaded for free.


The notion of parallel text alignment derives from Harris’ (1988) concept of bitext, and refers to (a) establishing links between linguistic units of at least two texts, (b) representing such links on screen, and (c) storing them for future access. Some aligners, such as Animalign, work at subsentential levels, but most of them align sentences. Generally, a text alligner imports files with (almost) identically formatted texts and connects them in a new file—usually, only two files at a time. Results are presented in columns or on a split screen. An editing function usually lets users to correct the automatic alignment and merge and split aligned sentences, or leave empty slots.

Aligned texts may be analyzed, searched, and manipulated for research or professional purposes. Hence, text aligners usually feature as subsidiary tools mainly in concordancers and in translation memory systems, although there some standalone programs as well, both commercial (e.g., ABBYY Aligner) and free. In research, aligners may be used to easily contrast an original with its translation or to compare alternative translations of a single source text, and also to study bilingual terminology and phraseology. Professional translators often use them to build translation memories from stored translations. Text aligners in concordancers usually offer many possibilities of analysis, whereas those in translation memory packages typically offer a wider range of input and output formats.

There is a wide range of software packages including standard operations available to the public. Some standard operations are the creation of concordances and wordlists and the provision of statistics.

A concordancer is a piece of software which allows users to retrieve all occurrences of a particular word or phrase in a corpus, together with the segment of text in which they are located. This segment is called the concordance line. The basic investigation procedure for querying text corpora consists of producing multiple concordance lines, also known as KWIC concordance, where KWIC stands for Key Word In Context (‘Key word’ refers to the searched word). Apart from listing all the occurrences of a word (some programs also provide sentence and paragraph length concordances), and revealing the contexts in which it appears, KWIC concordances can also be sorted in different ways (i.e. alphabetically, to the left or to the right of the key word). They can also be expanded to reveal more of the context, and some programs even offer a collocational profile of the key word in a set of concordance lines. Other facilities that some software packages offer are, for instance, the listing of all the word-forms in a corpus, in frequency or alphabetical order. Word frequency profiles give statistical information that is useful for investigating different measures in a corpus, such as type-token ratio and lexical density.


Audio data (e.g. from interviews, think-aloud commentaries, retrospective commentaries) and audiovisual data (e.g. from screen recordings with voice-overs, video recordings, films) can be analysed by coding various segments and then combining codes to form categories that can contribute to theory-building or testing hypotheses. The applications listed below can all be used for the type of data collected in translation process research and provide various possibilities for calculating descriptive statistics.


Quantitative research with clear predictive or confirmatory objectives often requires different kinds of statistical operations. When gathered, quantitative data retains a qualitative aspect or when a study is only looking for general tendencies, descriptive statistics are sufficient. However, if we want to know the statistical relevance of differences studied in a sample or the exact magnitude of relation between parameters, and to be able to extrapolate our findings to a whole population, we need to apply inferential statistics. The computer programs described below help with organising and validating quantitative databases, provide a wide range of data transformation facilities, support descriptive and inferential statistical operations and make it possible to generate graphs in order to visualise partial or total quantitative results.
