Examining the Effect of Subliminal Priming on Ambiguous Figure Perception
Misa Tsuruta, M.A.1

Abstract ~ Figure-ground organization is a kind of perceptual organization that has been studied in Gestalt psychology. Ambiguous/reversible figures can evoke two different percepts. When we see ambiguous figures, sooner or later our perceptual system determines one side that stands out as the figure, while the other side forms the ground and becomes shapeless. Subjects were subliminally trained with the half-figures of the target
1: Department of Psychology, Graduate Faculty, New School University, New York, USA An extended version of this paper served as partial fullfillment for the requirements of Research Methods at New School University Acknowledgments: I would like to express my gratitude to Dr. Arien Mack for her patient instruction on the subject of perceptual organization. Moreover, without the continuous help of Zissis Pappas this project could literally not have been completed. A friendly thank you to Keiko Yashima, who created the figures used in the experiment. My last thank you goes to my husband, Masayoshi Tsuruta, who gave me a brief introduction to Gestalt psychology many years ago. Address correspondence to Misa Tsuruta, tsurm152@newschool.edu

Effect of Subliminal Priming

ambiguous figures and then presented with the target figures. The result demonstrated above-chance level of consistency between the prime and the choice of the figure. From this result, it was concluded that subliminal priming of the figure had effects on figure-ground organization. Introduction In the investigation of visual perception, Gestalt psychologists made an indispensable contribution by asserting that perceptual processes were not simply determined by separate elements in visual stimuli (Peterson, 1999; Mack, Tang, Tuma, Kahn, & Rock, 1992). Those elements are not

    | Three groups of Subjects studied word-word paired associates after receiving instructions to learn using either (a) overt rote repetition of the word pair, (b) construction of an interactive scene in imagery, or (e) imagery of the objects non interacting and separated in "imaginal space." The study trial was followed by a test for stimulus recognition and for PA recall given recognition. The procedure was repeated on three different lists of 30 PAs. All words were concrete nouns selected for high imagery. There were 90 pairs shown in three lists of 30, each pair was presented for 10 sec in the window of a memory drum. Followed by a test list of 60 words, the left-hand (“stimulus”) members of the 30 pairs of the study list scrambled in with 30 new concrete nouns (as “distractors or lures”). Each test word appeared for 10 see during which Subject (a) rated the likelihood that he had seen it on the prior study list by checking off a 5-point scale ranging over the values "Sure Old, Think Old, Don't know, Think New, Sure New," and (b) if Subjects thought the word had appeared in the prior list, he tried to recall the other word paired with it. No feedback was given on test trials. Each list received one study trial followed by one test trial. The three lists were presented in the same order to all subjects, with a 60 sec rest between lists. Emphasized overt repetition of each word pair. Subjects were 30 high school graduates (ages 17-22) solicited through an ad in a local newspaper. Paid for their 1-hr participation. Ten subjects, five males and five females, were assigned in random alteration to three instructional conditions.…

    Understanding this factor is crucial to improve one’s comprehension of how perception operates when viewing an assortment of stimuli. Nonetheless, Clarks article opens the reader’s mind to ideas about reality by giving examples of viewing life from different viewpoints. As Clark writes, “Depending on how adept you are at focusing your concentration, you may notice a slight shift in your perception – a weird jump in realty, where you are suddenly viewing the world from a different perspective” (Clark par. 1). By allowing individuals to think from a different perspective, they can shift their perception into grander…

Gestalts Law of Perceptual Organization explains six forms of psychology within its sector, The Law of Pragnanz which derived from a German word which means good figure; The Law of Similarity states that similar objects are perceived as being grouped together; The Law of Proximity explains that objects that are in close proximity appear to be grouped together; The Law of Common Fate informs us that objects moving in the same direction appear to be…

    The mental rotation task consisted of at least 70 trials presented on the computer monitor (Francis, Neath, & VanHorn, 2008, pp. 105-107). On each trial, participants saw two 3-D block shapes, one to the left and one to the right. Each block shape is within a circle. The two shapes were either identical, or mirror-reversed. One shape was also…

    Face perception is the process by which the brain and mind understand and interpret the human face. The cognitive and neural processes in face recognition differ greatly from those observed for object recognition. Both objects and faces are generally considered to be “viewpoint-dependent” meaning that performance in recognition is better when viewed from a familiar viewpoint. However when considering Biederman’s (1987) recognition-by-components theory he found that objects can be recognised equally as easily from all viewpoints. This is due to his belief that objects are recognised from the individual basic shapes that make the whole object; these are called “geons”. Recognition of an object occurs when the stored representation of an object best fits the geon based information. However according to Bruce and Young (1986) face recognition starts with the visual encoding of the features of a face, meaning that one is able to identify a face viewed from any angle through its features as identified in their model for face recognition. Whilst cognitive and behavioural processes are involved for face and object recognition, and said processes vary greatly between the two, there are also important neural processes involved in face and object recognition. Particularly the role of the Fusiform face area for face recognition and the role of the inferotemporal cortex for object recognition. Other psychologists explain the different recognition processes between face and object recognition through the theory of expertise, whereby face recognition does not have face specific processing but is due to individuals having a greater expertise at individuating faces. Diamond and Carey’s (1986) study aims to support the expertise hypothesis by showing that experts process their objects of expertise in the same way as faces, therefore supporting their hypothesis that it is not due to…

    Historically, mental representations have been interpreted by analogy with physical representations, i.e. descriptions and classifications devised for physical representations have been applied to mental representations (Paivio, 1986).
