Abstract

This research aims at developing a hybrid choice model (HCM) where a perceptional variable is measured by means of adjectives reported by individuals. Due to the qualitative nature of adjectives, the main challenges of the study involve their quantification and their integration into HCMs. In order to address these issues, we first obtain measures of the strength of the adjectives on the scale of the perceptional variable by using ratings from external evaluators. Second, an advanced measurement model of the perceptional variable is specified, in order to account for variations occurring in the answers from the evaluators.

Time perception

The study of time perception or chronoception is a field within psychology, cognitive linguistics and neuroscience that refers to the subjective experience, or sense, of time, which is measured by someone's own perception of the duration of the indefinite and unfolding of events. The perceived time interval between two successive events is referred to as perceived duration. Though directly experiencing or understanding another person's perception of time is not possible, perception can be objectively studied and inferred through a number of scientific experiments.

Evaluation

In common usage, evaluation is a systematic determination and assessment of a subject's merit, worth and significance, using criteria governed by a set of standards. It can assist an organization, program, design, project or any other intervention or initiative to assess any aim, realisable concept/proposal, or any alternative, to help in decision-making; or to ascertain the degree of achievement or value in regard to the aim and objectives and results of any such action that has been completed.

Quantifier (logic)

In logic, a quantifier is an operator that specifies how many individuals in the domain of discourse satisfy an open formula. For instance, the universal quantifier in the first order formula expresses that everything in the domain satisfies the property denoted by . On the other hand, the existential quantifier in the formula expresses that there exists something in the domain which satisfies that property. A formula where a quantifier takes widest scope is called a quantified formula.
