Political objects, like national flags, arouse emotions even when they are subliminal stimuli. Through two experiments that show subliminal stimuli to the subjects, this article analyzes if those emotions are positive or negative ones—that is to say, if they enhance an inclusive reaction or an excluding one. Besides, the article compares the intensity of the flag’s emotional effect with that of the emoticons, which are figures intended to represent emotional reactions or states. Findings confirm that the Spanish flag, as a subliminal stimulus, influences the opinions of the participants. However, it has had a lower effect than that obtained in previous, similar experiments. Emoticons produce a much more intense type of response than flags. The experiments (n = 85; n = 126) enlarge the knowledge about the emotional effects of political objects of nonconscious perception. Besides, we present an original methodological contribution: the use of emoticons to alter political views.

This article presents a discussion of neurocognitive hacking and its potential for use at the strategic, operational, and tactical levels of cyber conflict. Neurocognitive hacking refers to the ability to activate specific neural areas of the brain, via subliminal or supraliminal stimuli, to shape the behavioral outcomes of an adversary. Research suggests that awareness of mortality-related stimuli has neural correlates in the right amygdala and left anterior cingulate cortex and mediates negative behavior toward out-group members, including unconscious discriminatory behavior. Given its in-group/out-group dynamic, the phenomenon could be exploited for use in information operations toward target populations, specifically ones that are multiethnic, multicultural, or multireligious. Although development of the theoretical framework behind neurocognitive hacking is ongoing, mortality-related stimuli are proposed to activate one’s unconscious vigilance system to further evaluate the locus and viability of the suspect stimuli. Research suggests that the subsequent discriminatory affective reactions directed toward out-group members are representative of automatic heuristics evolved to protect the organism in the event a stimulus represents a more serious threat to survival. Therefore, presenting mortality-related stimuli over computer networks to targeted audiences may facilitate the ingestion of tailored propaganda or shaping of specific behavioral outcomes within a population, including sowing division in a target community or weakening support for a specific political regime.

In a series of three experiments the influence that information unrecognised by the subjects has on the effectiveness of occurring cognitive activity is studied. With this aim 3 types of stimulus were compared which for one reason or another were not afforded sufficient attention, namely: unconscious meanings of polysemantic information, stimuli presented at the subliminal level, and intentionally ignored distractors. All the listed types of stimuli are united in that the subjects were not able to give an account of them, i.e., these stimuli were not processed attentively. It is assumed that each of the types of stimuli studied is in actuality perceived, which can be judged by the impact they have on occurring cognitive activity. The purpose of the present research is the comparison of this impact: apart from the determination of the impact of unperceived stimuli on the information directly associated with them (priming-effect registration), also identified is the presence/absence of an overall interference effect rendered by the unperceived stimuli on the performance of occurring cognitive activity. To this end, each experiment had a control condition the aim of which was the creation of the possibility for the subjects to perceive stimuli unnoticed under experimental conditions. An experimental priming paradigm was used in combination with image-classification and lexical-decision tasks.

The results of the experiments conducted demonstrate that all types of stimuli ‘slipping the attention’ are assimilated, but their effect on occurring cognitive activity is varied. Thus, subliminally presented information aids, and distractors, on the contrary, hinder the solution of tasks associated with them, whereas unperceived meanings of polysemantic information hinder not only the solution of the tasks directly associated with them, but also the performance of any other cognitive activity for which they serve as a context. The effect of subliminal stimuli on occurring cognitive activity in the present research is explained by the spreading activation in the memory, the effect of distractors – by the inhibition of irrelevant representations in the information-processing system. For an explanation of the consequence of unperceived meanings of polysemanticity, not only an inhibition model was used, but also an unconscious negative choice model which assumed the necessity of making a special decision on non-perception.
