The Impact of Imagery on Perception

What you imagine in your mind impacts what you perceive in the world.

What you imagine in your mind impacts what you perceive in the world.

New research from Vanderbilt University has found that mental imagery—what we see with the “mind’s eye”—directly impacts our visual perception. The research was published online June 26 by the journal Current Biology in a paper titled, “The Functional Impact of Mental Imagery on Conscious Perception.”

“We found that imagery leads to a short-term memory trace that can bias future perception,” says Joel Pearson, research associate in the Vanderbilt Department of Psychology. and lead author of the study. “This is the first research to definitively show that imagining something changes vision both while you are imagining it and later on.”

“These findings are important because they suggest a potential mechanism by which top-down expectations or recollections of previous experiences might shape perception itself,” Pearson and his co-authors write. Continue reading

Rapid Switching

You can either learn or remember.

You can either learn or remember.

You can either learn or remember. Researchers at Duke University used functional magnetic resonance imagery (fMRI) to demonstrate this competition in a group of college age adults. Their evidence is compelling. Many psychological studies have also shown that you can either listen for new information or consider your response to that information (remembering similar past events). One or the other – not both simultaneously.

New OR old rather than new AND old. You can either listen to your partner’s complaint OR search your memory for a snappy comeback – not both simultaneously.

The problem, of course, arises when the switch is turned to focus the brain on remembering when learning is indicated – or visa versa. Too many times I’ve come back with a response to my wife’s information that was completely off or indicated that I was not intent or focused on what she was saying. Rather, I was “remembering” similar information – and probably getting side-tracked by a mind tangent – rather than “learning” I was “remembering”. Oops!

“I can do that, daddy!” My father heard these words often from me as a kid – especially after a short demonstration of a skill he was trying to teach me. He’d invariably turn the task over to me whereupon the task would get horribly bungled because I had no clue what I was doing. I was remembering a similar task rather than paying attention to the lesson at hand. The switch was in the wrong position. Oops!

So how does one manually turn the switch from one state to the other? Certainly this could be a valuable skill for many tasks including academic learning, attending to the needs of a partner, or learning how to operate equipment.

Are Killer Repressed Memories a Myth?

A percentage of veterans (and by extension, some civilians) who have experienced traumatic events have a built-in coping mechanism that appears to repress traumatic memories in order to make life more satisfying and livable. And the strategy works well for them!

A percentage of veterans (and by extension, some civilians) who have experienced traumatic events have a built-in coping mechanism that appears to repress traumatic memories in order to make life more satisfying and livable. And the strategy works well for them!

“Going back to the days of Sigmund Freud, psychiatrists and mental health experts have suggested that repression of traumatic memories could lead to health problems. Yet we have found little evidence that repression had an adverse health impact on combat veterans exposed to psychological trauma many years later.”

Joseph Boscarino, Ph.D. and Tulane University investigator Charles Figley, Ph.D., have been studying the effects of repressed memories in Vietnam war and other war veterans to help understand the relationship between repressed memories and physical ailment and longevity.

For years I had worked under the belief that horrific traumatic experiences should “come out” to be resolved or relieved of their emotional charge – and that suppressing those memories was tantamount to denial – leading to terrible life consequences. I’ve worked with hundreds of clients, many of whom were veterans. For those who chose to disclose their traumatic emotional baggage, swift release of the psychic energy often produced a noticeable increased sense of well-being and life satisfaction – that lasted.

However, according to Boscarino and Figley, a percentage of veterans (and by extension, some civilians) who have experienced traumatic events have a built-in coping mechanism that appears to repress traumatic memories in order to make life more satisfying and livable. And the strategy works well for them!

In these cases, “Repression is a self-regulator and a method of memory management,” Dr. Figley said. “In other words, ‘keeping your stressful memories inside or it will kill you’ is a myth.”

To both practitioner and veteran, I would say – “If what you are doing is working well for you, no need to ‘rock the boat’ for the sake of therapy.” Like my old pappy used to say, “If it ain’t broke – don’t fix it!”

To that I would add – just because you experienced traumatic events does not necessarily mean you need therapy to “resolve your issue” or that you must have repressed memories that will affect you physically if not properly dealt with – usually by expressing them. Maybe all you need to do is continue to do what you’re doing now. Sometimes the hunt for repressed memories itself is more traumatic than the memories sought after – and can cause more psychological damage than repressing the memories.

However (and this is important) – if someone close to you suggests therapy, take them up on the idea. And if you suddenly find yourself acting out for no reason whatsoever – like losing your temper when your wife tells you she’s going to brew another cup of coffee or sit in a different chair – or maybe you start losing sleep at night due to recurring nightmares – consider therapy to relieve you of some suppressed emotional charge. The investment may just make the difference between “just getting by” emotionally and loving and living your life to the fullest.

Eye and Body Movement for Problem Solving?

Directing a person's eye movements or attention in specific patterns can also aid in solving complex problems.

Directing a person’s eye movements or attention in specific patterns can also aid in solving complex problems.

A new study appearing in an upcoming issue of the journal Psychonomic Bulletin & Review, is the first to show that a person’s ability to solve a problem can be influenced by how he or she moves.

“Our manipulation [of the body] is changing the way people think,” said University of Illinois psychology professor Alejandro Lleras, who along with Vanderbilt University postdoctoral researcher Laura Thomas, conducted the study. “In other words, by directing the way people move their bodies, we are – unbeknownst to them - directing the way they think about the problem.”

“The results are interesting both because body motion can affect higher order thought, the complex thinking needed to solve complicated problems, and because this effect occurs even when someone else is directing the movements of the person trying to solve the problem,” Lleras said.

According to Lleras, this type of consciousness, “embodied cognition,” describes the link between body and mind in a new and insightful way.

Advantages of Having a Grandparent

Spending time with a grandparent was found to equip adolescents with better social skills and fewer behavior problems.

Spending time with a grandparent was found to equip adolescents with better social skills and fewer behavior problems.

Grandparents are a positive force for all families but play a significant role in families undergoing difficulties,” said Shalhevet Attar-Schwartz, PhD, of The Hebrew University of Jerusalem. “They can reduce the negative influence of parents separating and be a resource for children who are going through these family changes.”

The study appears in the February Journal of Family Psychology, published by the American Psychological Association (APA). The researchers found that children and adolescents whose parents have separated or divorced see their grandparents as confidants and sources of comfort. Spending time with a grandparent was found to equip adolescents with better social skills and fewer behavior problems, especially among those children living in single-parent or stepfamily households.

As in previous studies, this research found that grandchildren are closer to their maternal grandparents and closest to their maternal grandmothers.
