  3. WHAT IS WHAT IS MENTAL IMAGERY ? MENTAL IMAGERY ? “Representation & experience of sensory information without a direct external stimulus” Pearson, Naselaris, Holems & Kosslyn, 2015 TiCS

  4. Galton, 1880 WHEN MIGHT WHEN MIGHT WE USE MENTAL WE USE MENTAL IMAGERY? IMAGERY? Thinking of the breakfast table this morning Remember a highlight from your last date - - - - Type of Bread Tea or Coffee Design colors - - - - Café or Restaurant Music Clothes Smell

  5. Wilhelm Wundt German physiologist & philosopher - Introspection - theater of consciousness - spotlight of selective attention B. F. Skinner American psychologist, behaviorist, author, inventor & social philosopher - behaviorism -The pigeons - Black box IT IS VALID IT IS VALID TO ASK TO ASK THESE SORT THESE SORT OF Q OF Q BECAUSE BECAUSE… … Noam Chomsky American linguist, philosopher, cognitive scientist, historian, social critic & political activist - criticized behaviorism - 23 years old PHD student

  6. ROLES OF IMAGINATION Motivation Mcmahon 1973 AJP Memory Emotion Prospective Thoughts Addis & Wong 2007 Neuropsychologia Schacter & Addis 2012 Neuron Holmes & Mathews 2010 Clinical psychology review - a common brain network underlies both memory and imagination. - the ability of individuals to re- experience episodes from the past and also imagine or pre- experience episodes that may occur in the future. - mental images of goal objects serve as motives by providing energization and direction . - Mental imagery acts as an “emotional amplifier” in both negative and positive emotional states and in many emotional disorders.

  7. IMAGERY DEBATES 1991 1991 Descriptive Descriptive Depictive Depictive Michael Michael Tye Tye Imagery does not rely exclusively on the same sorts of representations that underlie language. “visual thinking” requires a combinatorial system—a language of thought—that itself is not in any sense “pictorial.” Kosslyn 2005 Pyshylyn 2003

  8. ARISTOTLE . . . we can call up a picture, as in the practice of mnemonics, by the use of mental images . . . “the soul never thinks without a fantasma”. DE ANIMA 350 BC The nature of memory and its process has now been explained as the persistent possession of an image, in the sense of a copy of the thing to which the image refers, and it has been further explained to what faculty in us this belongs, viz. to the primary power of sensation . . . ON THE MEMORY 350 B.C

  9. HOBBES imagination being only of those things which have been formerly perceived by sense, either all at once or by parts at several times, the former, which is the imagining the whole object as it was presented to the sense, is simple imagination, as when one imagines a man or horse which he has seen before. The other is compounded, as when, from the sight of a man at one time and of a horse at another, we conceive in our mind a centaur. Leviathan 1651

  10. LOCKE . . . there is an ability in the mind when it will revive them again, and as it were paint them anew on itself, though some with more, some with less difficulty . . . An Essay Concerning Human Understanding 1695

  11. BERKELEY [F]or myself, I find indeed I have a faculty of imagining, or representing to myself, the ideas of those particular things I have perceived, and of variously compounding and dividing them. I can imagine a man with two heads, or the upper parts of a man joined to the body of a horse. I can consider the hand, the eye, the nose, each by itself abstracted or separated from the rest of the body. Principles of Human Knowledge 1710

  12. KOSSLYN mental images are distinct from language because they depict, not describe, information. The cognitive neuroscience of mental imagery 1995

  13. SUPER BRIEF HISTORY OF MEASURING IMAGERY Questionnaires (VVIQ) Mental Rotation (3D,Motion) Reaction Times Binocular Rivalry VVIQ in 1973 VVIQ-2 in 1995 VOIQ in 1998 VMIQ-2 in 2008 Showing Images and how quick and slowly react to it Task of rotating something in your mind and imagine colors visual phenomenon that involves perceptual switching in response to different images presented to each eye. The VVIQ consists of 16 items groups of 4 items in which the participant is invited to consider the image formed in thinking about specific scenes and situations. in four

  20. (ZEMAN ET AL, 2010) 4 MAIN CONCLUSIONS CONCLUSIONS  successful performance on standard tests of visual imagery does not always require the experience of visual imagery.  studies of visual imagery deficits should address both subjective and objective aspects of imagery.  activation of posterior visual cortices is required for the experience of visual imagery but not for the performance of imagery tasks.  Value of fMRI in cog tasks.

  29. 2017 Here we ran a group of self described congenital congenital aphantasics aphantasics on the binocular rivalry visual rivalry visual imagery imagery paradigm paradigm to measure the strength of their sensory imagery. If congenital aphantasia is a complete lack of visual imagery, we should expect no facilitative no facilitative priming effects of visual imagery on subsequent rivalry. However, if congenital aphantasia is instead a lack of metacognition, metacognition, or failed or failed introspection introspection, then we may expect to observe some priming, despite the subjective reports of no imagery. binocular priming

  31. 2021 our study provides new methods for measuring the sensory strength of attentional templates of attentional templates. We also demonstrated that visual imagery and attention relationship relationship with each other. imagery has been shown to be a ‘cognitive simulation tool simulation tool’ to help perform a range of different cognitive tasks. Such a theory highlights the ubiquity of imagery across human cognition and paints an exciting picture of imagery as a a keystone element element to to understanding for a range of other understanding for a range of other cognitive tasks. cognitive tasks. strength Experiment Experiment 1 1— exploratory analysis relationship between imagery, attentional templates attentional templates feature feature- -based based attention attention hold a close of imagery, the cognitive tool tool’ or ‘sensory sensory and and Experiment Experiment 3 3— investigating attentional templates attentional templates in in aphantasia aphantasia Experiment Experiment 2 2— investigating feature attention attention in in aphantasia feature- -based aphantasia based Experiment Experiment 4 4— investigating the effect of irrelevant irrelevant visual information information on attentional templates attentional templates keystone further further unlock unlock visual on

  32. Experiment 1 1— Experiment IMAGERY TASK presented with the letter ‘R’ or ‘G’, which cued them to imagine the red horizontal gratings or the green vertical gratings. ATTENTION TASK presented with the plaid stimuli (brightness levels: 100, 50, 25, 5% or (0%), random) for 4 s and were asked to attend to the image they were cued to.

  33. Experiment 1 1— Experiment RESULT RESULT • This suggests that even when no plaid participants were forming an attentional biased subsequent perception. • priming in template condition correlated positively with attention conditions. • These data imagery imagery may may be related related to to attentional attentional templates than to feature attention. was present template that the attentional all feature suggest be more more closely templates that closely

  34. Experiment 2 2— Experiment IMAGERY TASK The imagery task was the same as in the previous experiment (figure 1a). Participants completed two blocks of 50 imagery trials (10% mock/catch trials), resulting in a total of 100 trials. ATTENTION TASK The attention task was the same as in the previous experiment (figure 1b) except there was only one brightness condition, 100%. completed the VVIQ. All participants
