STUDY REGARDING THE RATIONALE OF COFFEE CONSUMPTION ACCORDING TO GENDER AND AGE GROUPS CRISTINA SANDU * University of Bucharest - Faculty of Psychology and Educational Sciences, Romania Abstract This research aims to study why people consume coffee. Thus, we have used a questionnaire to assess consumer behavior regarding coffee selection. The study was conducted on three age groups, each composed of 20 people. The questionnaire used included 10 items with 3 possible answers. The subjects were asked to specify the amount of coffee consumed daily, where they drink coffee most often, and the place from where they buy coffee most often. The data collected from the responses to the questionnaire was processed using the chi square test SPSS statistical software. As such, the research objective was met and the coffee consumption behavioral patterns can be represented as a pyramid and ranked according to all the variables considered in this research. Keywords: coffee, behavior, gender and age differences. 1. INTRODUCTION Researchers have shown that too much caffeine diminishes the power of concentration, inducing a mild but permanent state of confusion. Those who do not consume coffee have better results in exams and tests, probably because they manage to retain the ability to focus for longer periods of time. Thus, it is important to know that a cup of coffee contains about 115 milligrams of caffeine, an espresso (filter) about 80 mg, while a "3 in 1" contains 65 mg of caffeine. Decaffeinated coffee is not totally caffeine-free and it actually contains 3 mg of caffeine. Soft drinks contain about 23 mg of caffeine per can. Motivation has specific features: Effort is the force or power used by an individual in pursuing its objectives. Persistence is related to the concepts of constancy and commitment to adopt a behavior or a task. * Email address: chrystina29@yahoo.com 18
Orientation refers to the quality and stability of behaviors taken and the direction of a person's motivational investment. Motivation is associated with three psychological processes (cognitive perspective): activation, targeting and persistence. 2. METHOD 2.1. Subjects \ Participants For the experiment we randomly selected three groups of 20 subjects each. The first group is composed of individuals of 18 to 25 years of age, of both sexes. The second group was randomly selected and contains only individuals of 26-30 years of age, of both sexes. The third group is represented by persons of 31-50 years of age, of both sexes. The questionnaire was applied to all three groups. The tested individuals are all from urban areas, but have different levels of education: gymnasium, high school or university. 2.2. Instruments and applied procedure The instruments used were an important aspect of the project in order to obtain valid data about the preferences of tested subjects. The main tool used in this research was a questionnaire consisting of 10 questions, each with 3 possible answers, which were aimed at coffee drinking preferences. 2.3. Experimental design The research hypothesis of this study is: There is a hierarchy of motives that influence coffee consumption, and these vary by consumer age and gender. The objective of this research is to determine and rank the reasons people drink coffee. The fact that people have different preferences about coffee is well known, but the questionnaire aimed to determine whether the motivation that determines coffee consumption is also different according to age and gender. Being an experiment that attempts to determine and prioritize the reasons that influence coffee consumption, we took into account variables such as: age, gender, education level, the place where coffee is usually consumed, the place from where the coffee is frequently purchased and the amount of coffee consumed daily. 19

The majority of subjects said they buy their coffee from supermarkets. (27 out of 60 => 45%) 3. CONCLUSIONS We started from the idea that people who drink coffee have many reasons to do so and that their motivation may be different by age and gender. Therefore we have divided the subjects into three age categories (18-25 years, 26-30 years, 31-40 years), but the result analysis has been also structured by gender. We have applied a 10 question questionnaire, and the results have shown us that there is no statistically significant gender difference as to the reasons that lead to drink coffee. Both women and men choose to drink coffee because it gives them extra energy and what draws them to it is mainly the flavor and its taste. People in the first two age groups said they prefer to drink coffee in public places, and those from the third group said they buy it from the supermarket. In conclusion, these being the results, we can say that there are no gender differences in motivation related to coffee consumption. In the future, it will be necessary to check if there are differences among coffee consumers regarding its effects on attention and visual perception, using psychological tests that measure these dimensions.
