The Effect of Suggestive Cues in Influencing Human Perception

Suggestion is the medium through information of a perspective is shared. The act suggestion, conveyed through verbal, visual, or sensory cues, alters an individual’s behaviour or actions, defined as social influence. This research focuses on how social influence and suggestive cues shape human perception and investigates how suggestive verbal input influence perception of visual anomalies in images. Participants were divided in two groups and were shown images and questioned, with one of the groups receiving a verbal suggestive cue. The results suggest that suggestive cues influenced perception in certain participants; however, patterns across gender and age could not be conclusively established, likely due to the limited sample size. Psychological reactance was also observed, with several participants resisting the cues or forming interpretations contrary to the suggestion. Locus of control (LOC)—the belief regarding the extent to which outcomes are determined by one’s own actions versus external forces—has been linked to individual differences in suggestibility. These preliminary findings suggest that suggestion can influence visual perception, but individual differences and task context may change this effect. The research findings contribute to understanding of how humans process suggestion and highlight the complexity of perception as shaped by social influence.
