Abstract: The psychological impact of entertainment material, visual objects, brands and advertising, commercial communication, the response to an individual presenting a message, or to an individual seeking public office can be assessed using methods employing measurements of SSVEP or SSVER phase increase and gaze tracking of subjects in a variety of ways. Various psychological states may be analyzed in order to accurately predict success and to enable early modification in development stages of products or communication.

Abstract: A method of quantitatively assessing the effectiveness of an audiovisual, visual or audio advertisement including the steps of: presenting the advertisement to a plurality of subjects, the advertisement having a sequence of audiovisual, visual and/or audio features which occur as a function of time; obtaining, during presentation of the advertisement, EEG signals from the subjects from predetermined scalp sites thereof; calculating SSVEP amplitudes and/or phase differences from EEG signals obtained from the predetermined scalp sites in order to obtain output signals which represent predetermined psychological states of each subject to the features as a function of time; combining the output signals from the subjects to obtain pooled output signals; and displaying the pooled output signals to thereby enable quantitative assessment of the subjects' responses to the features of the advertisement in order to assess the effectiveness of the features of the advertisement.

Abstract: A method for determining the psychological impact of entertainment material having at least first and later episodes, the method including the steps of: (a) presenting a first episode to a target group of subjects, (b) after a predetermined period of time, presenting the later episode to the target group of subjects; (c) determining brain activities of the target group of subjects whilst the later episode is being presented to the target group of subjects; and (d) evaluating the psychological impact of the entertainment material by reference to the levels of brain activities determined in step (c). The method of presenting material and determining brain activities also being used for determining the suitability of an actor from a group of actors or selecting a person from a group of persons for a public role.

Abstract: A method of improving a computer game, the method including the steps of: (a) causing a player to play the computer game in which various game situations are presented to the player during the course of the game; (b) recording game situation parameters corresponding to the various game situations of step (a); (c) determining brain activity of the player during each of the game situations which are presented to the player; (d) evaluating effectiveness of the game situation parameters by reference to brain activities determined in step (c) for each of the game situation parameters recorded in step (b); and (e) improving the game by eliminating or modifying those game situations which have low levels of brain activity as determined in step (d).

Abstract: A method of evaluating characteristics of a brand or product including the steps of: (a) presenting the brand or product to the subject during a first period; (b) determining brain activity of the subject during the first period; (c) presenting neutral visual and/or audio material to a subject during a second period; (d) determining a reference level of brain activity of the subject during the second period; and (e) evaluating attributes associated by the subject with the brand or product by determining differences in brain activities between the first and second periods.

Abstract: A method of evaluating the response of a subject to visual features of a visual display, the method including the steps of: (a) presenting a visual display having particular visual features to the subject during a first period; (b) determining brain activity of the subject during the first period; (c) presenting reference display material to a subject during a second period; (d) determining reference brain activity of the subject during the second period; (e) tracking the gaze position of at least one of the eyes of the subject on the visual display during the first period; and (f) evaluating the response of the subject to particular visual features of the visual display by determining differences in brain activity determined between steps (b) and (d) when the gaze of the subject is directed at the particular features.

Abstract: A method of assessing the cognitive aptitude of a subject to a predetermined task, the method including the steps of: (i) presenting to the subject a group of cognitive tasks; (ii) detecting brain response signals from the subject during presentation of the group of cognitive tasks; (iii) calculating SSVEP amplitude, phase and/or coherence responses from the brain response signals; and (iv) comparing the SSVEP responses to known SSVEP responses obtained from individuals with high and/or low aptitudes to the predetermined task in order to assess the subject's aptitude for the predetermined task.
