Arc of Attentional Focus: Has Someone Picked Your Pocket While You Experienced “Inattentional Blindness”?

Apollo Robbins

Apollo Robbins

Glitches in human perception and cognition are vividly illustrated in Apollo Robbins’ interactive Las Vegas show, “The Gentleman Thief.”

He tells his “targets” in the audience that he is about to steal from them, then uses visual illusions, proximity manipulation, diversion techniques, and attention control, to complete his imperceptible heists.
Robbins returns belongings, which kept him out of trouble when he lifted possessions of former US President Jimmy Carter’s Secret Service agents.

In addition to the entertaining curiosity of Robbins’ feats, his skill is relevant to improving perceptual skills in normal and cognitively-impaired people, and in reducing traffic accidents, industrial mishaps, and security violations.

He overcame congenital motor-skill deficits by monitoring the focus of a target’s attention: “If a person is focused elsewhere, a thief can put his whole hand in [a pocket] and steal.”

Kim Silverman

Like Kim Silverman, Research Scientist at Apple, Robbins creates “false assumptions…that look like reality…

The U.S. Department of Defense accesses Robbins’ skills at its Special Operations Command research-and-training facility at Yale University, where he an adjunct professor, despite his non-collegiate education.

Barton Whaley

Barton Whaley

Defense application of these perceptual manipulation skills were identified by Barton Whaley of the Naval Postgraduate School and Susan Stratton Aykroyd in their Textbook of Political-Military Counterdeception.

Their historical survey of deception and counter-deception practices asserted that conjurors’ principles were substantially more advanced than those used by U.S. political or military intelligence analysts in the 1970s.

Stephen Macknik

Stephen Macknik

SUNY Downstate’s Stephen Macknik and Susana Martinez-Conde collaborated with Robbins on Sleights of Mind: What the Neuroscience of Magic Reveals about Our Everyday Deception.
They reported empirical results supporting Robbins’s observation that the eye will follow an object moving in an arc without looking back to its point of origin.
The curved motions may be more salient, novel, and informative than predictable linear edges, so attracts greater attention and is useful in deceptive illusions.

Susana Martinez-Conde

Susana Martinez-Conde

Cognitive errors that lead to perceptual illusions of “magic” suggest diagnostic and treatment methods for cognitive deficits from brain trauma, autism, ADHD, and Alzheimer’s disease, they argued.

Insights from magic performance can help patients focus on the most important aspects of their environment, while suppressing distractions that cause confusion, disorientation, and “inattentional blindness” (focusing so intently on a single task that one fails to notice things in plain sight).

Richard Wiseman

Psychologist and magician Richard Wiseman of the University of Hertfordshire demonstrated inattentional blindness when viewers fail to notice environmental changes when focusing on a card trick. 
Similarly, Transport of London’s Public Service Announcement reminds viewers that it’s easy to miss things you’re not expecting in “Did you see the Moonwalking Bear?

Wiseman argued that people can “recognise hidden opportunities in … life,” by reducing perceptual blindness, in his research-based book, Magic in Theory: An introduction to the theoretical and psychological elements of conjuring.

Daniel Levin

Daniel Levin

Daniel Simons

University of Illinois’s Daniel Simons and Daniel Levin of Vanderbilt University demonstrated observers “seeing without seeing” in experiments involving people passing a basketball as woman in a gorilla suit walked through the action.

With Harvard’s Christopher Chabris, Simons reported that half of observers said they did not see the gorilla when they were counting the number of ball passes by one team.

Christopher Chabris

Christopher Chabris

However, the same people easily recognized the gorilla when they were not focused on a distraction task.

Edward Vogel

This findings illustrates that most people are unable to effectively multitask because they have limited capacity to hold a visual scene in short-term memory (VSTM), according to University of Chicago’s Edward K. Vogel and Maro Machizawa of Hiroshima University and separately by Vanderbilt’s René Marois and J. Jay Todd.

Gustav Kuhn

Gustav Kuhn

Gustav Kuhn of University of London collaborated with magician Alym Amlani and Ronald Rensink of University of British Columbia to classify cognitive, perceptual, and physical contributors in Towards a Science of Magic:

  • Ronald Rensink

    Physical misdirection by a magician’s gaze or gesture in “joint attention,”

  • Psychological misdirection with a casual motion or prolonged suspense to distract from the trick’s mechanics,
  • Optical illusions that distort the true size of an object,
  • Cognitive illusions to prolong an image after the object has been removed,
  • Physical force and mental force influence “freely chosen” cards or other objects in magic tricks.

Rene Marois-J Jay Todd

Perceptual and cognitive illusions can cause people not to see things that are clearly present, which can lead to overlooking interpersonal cues and life opportunities.
Even more serious is the link among inattention, traffic accidents, and victimization by criminals.

Mindful awareness helps people attend to the present moment, to more attentively experience opportunities and relationships while mitigating potential perceptual misinformation.

How Much Does Appearance Matter?

Hillary Clinton

Even before Hillary Clinton‘s historic 2016 campaign for President of the U.S., attorney and image consultant Orene Kearn,questioned the impact of Clinton’s appearance on her perceived competence as US Secretary of State.

Orene Kearn

Perceived attractiveness was correlated with perceived competence and likeability in a meta-analysis by Michigan State University’s Linda A. Jackson, John E. Hunter, and Carole N. Hodge.
They reported that physically attractive people are perceived as more intellectually competent, supporting  status generalization theory and implicit personality theory.

Nancy Etcoff

Women who wore cosmetics were rated more highly on attractiveness, competence, likability and trustworthiness when viewed for as little as 250 milliseconds, found Harvard’s Nancy L. Etcoff, Lauren E. Haley, and David M. House, with Shannon Stock of Dana-Farber Cancer Institute, and Proctor & Gamble’s Sarah A. Vickery.

Models without makeup, with natural, professional, “glamorous” makeup

However, when participants looked at the faces for a longer period of time, ratings for competence and attractiveness remained the same, but ratings for likability and trustworthiness changed based on specific makeup looks.

Volunteers accurately distinguished between
judgments of facial trustworthiness vs attractiveness and attractiveness was related to positive judgments of competence, but less systematically to perceived social warmth.

The researchers concluded that cosmetics could influence automatic and deliberative judgments because attractiveness “rivets attention, and impels actions that help ensure the survival of our genes.”

Most people recognize the bias in assuming that attractive people are competent and that unattractive people are not, yet impression management remains crucial in the workplace and in the political arena.

Knowing without Knowing – Implicit Learning in Action

Lyn Abramson

Lyn Abramson

Implicit learning – knowing without conscious awareness – has positive effects like accelerating foreign language learning and developing more secure computer authentication systems.
It also has negative consequences like prejudiced, biased decision-making.
All of these effects require sufficient sleep to enable memory consolidation of implicit learning.

Patricia Devine

Patricia Devine

When implicit learning leads to inaccurate beliefs about others, the result is often prejudiced behavior.
In contrast,  when biased perceptions are about one self, they can lead to feelings of depression, anxiety, or grandiosity, according to University of Wisconsin’s William T. L. Cox, Lyn Abramson and Patricia Devine with Steven Hollon of Vanderbilt.

Brian Nosek

Brian Nosek

A validated way to identify hidden beliefs about race, age, gender, weight, and more is the Implicit Association Test, developed by University of Virginia’s Brian Nosek, Mahzarin Banaji of Harvard and University of Washington’s Anthony Greenwald.

Mahzarin Banaji

Mahzarin Banaji

Banaji and Greenwald’s popular book provides numerous examples of frequently used thinking short cuts that lead to biased beliefs, decisions, judgments, and behaviors.

Anthony Greenwald

Anthony Greenwald

Similarly, most people make quick assessments of others based on appearance using habitual strategies that don’t account for perceptual limitations, noted journalist Joseph Hallinan, who summarized research on bias, misperceptions, and judgment errors.

Joseph Hallinan

Joseph Hallinan

He cited the impact of situational framing on decision making:  When a decision option is posed as a potential gain, most people are less inclined to take risky decisions.
However, they are more willing to take risks if the option is positioned as a possible loss.

Kara Morgan-Short

Kara Morgan-Short

Implicit language learning was demonstrated by “immersion” listening to multiple native speakers.
University of Illinois at Chicago’s Kara Morgan-Short teamed with Karsten Steinhauer of McGill University and Georgetown’s Cristina Sanz and Michael T. Ullman to conduct brain scans on these language learners, and found they showed “native-like language processing.”
By contrast, explicit grammar training did not improve language learning.

Karsten Steinhauer

Karsten Steinhauer

Likewise, implicit learning principles can increase computer security authentication, useful in high-security nuclear plants or military facilities that usually require the code-holder to be physically present.

Cristina Sanz

Cristina Sanz

Security can be compromised when attackers:

  • Steal the user’s hardware token,
  • Fake the user’s identify through biometrics,
  • Coerce the victim into revealing the secret key or password (“rubber hose cryptanalysis”).
Hristo Bojinov

Hristo Bojinov

Unconscious knowledge” is a highly secure approach to biometrics authentication, demonstrated by Stanford University’s Hristo Bojinov and Dan Boneh, collaborating with Daniel Sanchez and Paul Reber of Northwestern and SRI’s Patrick Lincoln.

They included implicit learning principles in a computer game to subliminally deliver a security password without the user’s conscious awareness of the password.

Paul Reber

Paul Reber

Players “intercepted” falling objects in one of six non-random positions on a computer game screen by pressing a key corresponding to the screen position.
The game repeated a hidden sequence of 30 successive positions more than 100 times during game play.

Players made fewer errors when they encountered this sequence on successive rounds, suggesting they implicitly learned the sequence.
Skill re-tests after two weeks demonstrated that players retained this learned skill, but they were unable to consciously reconstruct or recognize fragments of the planted code sequence.

Patrick Lincoln

Patrick Lincoln

Team Bojinov’s implicit learning game demonstrated a new method of highly secure authentication that resists “rubber hose cryptanalysis” by implicitly training the user to enact the password without conscious knowledge of the code.
Their new project analyzes the rate of forgetting implicitly learned passwords and optimal frequency of security authentication refresher sessions.

However, this innovation in security authentication is dependent on the authenticator having sufficient sleep to consolidate implicit learning in memory, found Innsbruck Medical University’s Stefan Fischer, I. Wilhelm, and J. Born, who examined sleep’s impact on implicit memory formation in children ages 7- 11 and 12 young adults between ages 20 and 30.

Fischer’s team measured serial reaction time task before and after eight implicit learning sessions concentrated on rules underlying grammatical and non-grammatical language structures.
Most volunteer responded quickly, demonstrating implicit rule understanding, even though they couldn’t explain why their performance improved.

When adult participants had an interval of sleep between training sessions, their response times were quicker.
In contrast, well-rested children did not show a similar performance improvement, suggesting that sleep actually interferes with implicit performance gains among children.

Implicit learning can boost performance, seemingly “effortlessly,” but requires sufficient sleep to consolidate longer term performance improvements.
These findings are another argument against sleep deprivation in “Crunch Time” all-night work marathons.

Enabling Neurodiversity in the Workplace with Early Detection, Intervention

Eugene Edgar

Eugene Edgar

Reading and related language and information processing skills are crucial for effective academic and occupational performance.
For example, people with reading difficulties face challenges in completing education, securing post-college employment and advancing in careers, found University of Washington’s Phyllis Levine and Eugene Edgar.

However, early detection and intervention can equip people for effective performance in school and work situations by practicing required skills and learn problem solving skills to manage these information processing differences.

Kineret Sharfi

Kineret Sharfi

People with learning disabilities including reading difficulties face significant challenges: They are significantly less likely to attend 4-year college programs or graduate, noted Haifa University’s Kineret Sharfi and Sara Rosenbaum.

David Goldstein

David Goldstein

Similar results were reported separately in a study of U.S. high school graduates from classes of 1985-1990, interviewed in the next 5 year, by De Paul University’s Christopher Murray, with Donald E. Goldstein, Steven Nourse and Eugene Edgar of University of Washington.

Tomer Einat

Tomer Einat

Of even greater concern is that learning disabilities (LD) including low reading skills, were significantly associated with ADHD, school dropout age, and onset of criminal activity among Israeli-born prisoners, according to Bar-Ilan University Tomer Einat and Amela Einat of Tel-Hai Academic College.

Michelle Patterson

Michelle Patterson

Further, these information processing challenges were also prevalent among homeless adults in Canada, reported Simon Fraser University’s Michelle Patterson, Akm Moniruzzaman, and Julian M. Somers with Charles James Frankish of University of British Columbia.

Travis White-Schwoch

Travis White-Schwoch

For those with years of practice in reading, Northwestern’s Travis White-Schwoch noted that learning to read is a chief developmental milestone with lifelong consequences.”
His research colleagues Kali Woodruff Carr, Elaine C. Thompson, Samira Anderson, Trent Nicol, Steven G. Zecker, Ann R. Bradlow and Nina Kraus added “… an ongoing challenge has been to identify candidates for intervention at a young-enough age.

Kali Woodruff Carr

Kali Woodruff Carr

However, it’s possible to identify potential reading difficulty is possible as early as age three.
This early awareness can enable early remediation efforts including skill-building in phonics, sound blending, phonograms, and close listening for comprehension and memorization, suggested among multi-media interventions and practice processes by Johns Hopkins’ Crystal Kelly and Linda Campbell.

Travis White-Schwoch 2White Schwoch’s team asked 112 children ages 3 – 14 years to detect consonants while in a noisy environment.
These children selected and watched a movie in separate booths while wearing electroencephalograms (EEG) and headphones, which provided “babbling” (semantically anomalous English sentences) in the right ear and “da” sounds in the left ear as the movie’s audio played .

Samira Anderson

Samira Anderson

The group accurately predicted that children with higher scores on a test understanding sounds that make up words and sentences (“phonological awareness”) were were more able to quickly and accurately detect the “da” sound.
Similarly, higher performance on phonological awareness predicted higher scores on a literacy test a year later among 37 four year old pre-reading children.

Trent Nicol

Trent Nicol

Neurodiversity” at work is a more frequent topic in popular business publications, public policy and diversity efforts, so it’s essential to understand the complexity of acquiring information processing skills, and the adverse consequences for those who don’t master these capabilities.

Steven Zecker

Steven Zecker

As a result, progressive workplaces enable greater inclusion of these different abilities by offering skill enhancement opportunities for those whose reading difficulties affect their ability to perform their work responsibilities.

Reduce Rumination, Stress by Taking a Walk in Nature, Viewing Animals

More than 50% of people live in urban environments and most have relatively infrequent contact with nature, according to research published by the United Nations.

Theo Lorenc

Theo Lorenc

One consequence is that many urban dwellers with decreased exposure to nature report “changes in psychological functioning” including ruminative thoughts – repetitive thoughts about negative aspects of the self – and depressed feelings, found University College London’s Theo Lorenc, Mark Petticrew, and Steven Cummins with Stephen Clayton of University of Central Lancaster, and David Neary of University of Manchester, University of Liverpool’s Margaret Whitehead, Hilary Thomson of University of Glasgow,  University of York’s Amanda Jayne Sowden, and Adrian Renton of University of East London.

Stephen Clayton

Stephen Clayton

Contact with nature can affect cognitive performance as well as emotional experience: Children living in urban environments with consistent views of nature outside their windows, performed better on:

  • Working memory (backward digit span, backward alphabet span),
  • Impulse inhibition (matching familiar figures task),
  • Selective attention (Stroop color-word task),
  • Concentration (Necker Cube pattern control task), reported by University of Illinois Urbana-Champaign’s Andrea Faber Taylor, Frances Kuo, and William C. Sullivan.
Andrea Faber Taylor

Andrea Faber Taylor

Urban environments are thought to require substantial top-down voluntary attentional control to filter relevant from irrelevant stimuli.
At the same time, built landscapes can deplete cognitive resources, worsening performance on tasks requiring focused attention, noted University of Uppsala’s Terry HartigGary W. Evans of University of California, Irvine with Marlis Mang of Planning & Design Solutions.

Terry Hartig

Terry Hartig

Walking for 90 minutes in nature reduced ruminationblood flow, and neural activity in the subgenual prefrontal cortex (sgPFC), reported Stanford’s Gregory N. Bratman, Kevin S. Hahn, Gretchen C. Daily, and James J. Gross with J. Paul Hamilton of Laureate Institute for Brain Research.
This brain area has been linked to self-focused behavioral withdrawal and rumination among both healthy and depressed people.

Gregory Bratman

Gregory Bratman

More than 35 volunteers rated their proneness to ruminate with negative thoughts, then half walked alone for 90-minutes without music through undeveloped open space hills through grassland with scattered shrubs and oak trees along a paved path.
They were told to take ten photographs of “whatever captured their attention” to disguise the study’s hypotheses.

Urban vs Rural Walks

Kevin Hahn

Kevin Hahn

Remaining participants walked alone without music down a busy, paved six-lane road with traffic for the same time period.

Following the walks, volunteers again rated their likelihood to repeatedly think negative thoughts.
They also completed a brain scan and cognitive and emotional assessment instruments including:

Lee Anna Clark

Cynical Beliefs Linked to Lower Earnings, Poorer Health

Olga Stavrova

Olga Stavrova

People who hold cynical beliefs about human nature and the world have lower incomes than those with a more optimistic view, found University of Cologne’s Olga Stavrova and Daniel Ehlebracht.

Cynical beliefs are measured by statements including:

  • “I think most people would lie to get ahead,”
  • “It’s safer to trust nobody,”
  • “Most people will use somewhat unfair reasons to gain profit or an advantage rather than lose it.”
Daniel Ehlebracht

Daniel Ehlebracht

People who agree with these ideas may avoid cooperation, trust and collaboration with others and while focusing on monitoring, control, and preventing potential exploitation.

Volunteers who endorsed these self-protective behaviors and cynical beliefs reported lower personal income than people who demonstrate greater trust and interpersonal collaboration in studies using a representative sample of Americans between 1986 and 2012, and replicated with a representative German group between 2003 and 2012.

Robert McCrae

Robert McCrae

A related study showed that income-suppressing cynical beliefs are not associated with enduring personality characteristic measured by Robert McCrae of NIH and Paul Costa’s Big Five personality dimensions.

In addition, lower earnings were not explained by cynical individuals’ poorer health, lower education, and greater agreement with items that measure neuroticism and introversion.

Paul Costa

Paul Costa

However, some cynical beliefs are justified by the local environment, such as in counties with low levels of charitable giving, high homicide rates and high overall societal cynicism levels.
Survey data from 41 countries showed that people in these contexts who held cynical beliefs did not have lower personal income than those with more optimistic views.

Anna-Maija Tolppanen

Anna-Maija Tolppanen

Holding cynical beliefs about people was also associated with greater risk of dementia and death among the elderly in a study over 8 to 10 years, according to University of Eastern Finland’s Elisa NeuvonenMinna Rusanen, Anna-Maija Tolppanen, collaborating with Alina Solomon of University of Kuopio, Flinders University’s Tiina Laatikainen, with Tiia Ngandu of Finland’s National Institute for Health and Welfare, Hilkka Soininen of Hospital District of North Karelia, and Kuopio University Hospital’s Miia Kivipelto.

Alina Solomon

Alina Solomon

The team measured cynical distrust with the Cook-Medley Hostility Scale (CMHS) by University of Minnesota’s Walter Cook and Donald Medley, and cognitive status using screening, clinical phase, and differential diagnosis using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) criteria for more than 1450 people.

People with highest level of cynical distrust had higher risk of dementia after the researchers controlled for confounding factors including:

  • Age,
  • Gender,
  • Systolic blood pressure,
  • Total cholesterol,
  • Fasting glucose,
  • Body mass index,
  • Socioeconomic background,
  • Smoking,
  • Alcohol use,
  • Self-reported health,
  • Apolipoprotein E (APOE).
Tiina Laatikainen

Tiina Laatikainen

People with highest levels of cynical distrust were three times more likely to develop dementia than people with low levels of cynicism, even when Neuvonen’s team controlled for effects of dementia risk, including high blood pressure, high cholesterol and smoking.

Tiia Ngandu

Tiia Ngandu

This finding supports suggestions that people who are more open and optimistic have a lower risk for dementia.

Hilary Tindle

Hilary Tindle

In related findings, positive expectations about the future, and trait optimism were associated with reduced rates of coronary heart disease (CHD) and mortality in postmenopausal women, reported University of Pittsburgh’s Hilary A. Tindle, Yue-Fang Chang, Lewis H. Kuller, Greg J. Siegle, Karen A. Matthews, collaborating with Harvard’s JoAnn E. Manson, Jennifer G. Robinson of University of Iowa, and University of Massachusetts’ Milagros C. Rosal.

Michael Scheier

Michael Scheier

More than 97,250 white and black women with no signs of cancer and cardiovascular disease completed the Life Orientation Test–Revised (LOT-R) by Carnegie Mellon’s Michael Scheier and Charles Carver of University of Miami, plus the Cook Medley Questionnaire’s cynicism subscale.

Charles Carver

Charles Carver

Women who scored in the top quartile for optimism had lower age-adjusted rates of Coronary Heart Disease (CHD) and total mortality.
Black women with this optimistic perspective also had significantly less cancer-related mortality.

In contrast, those who scored in the top quartile for cynical hostility had significantly higher rates of CHD and total mortality, reinforcing the value of cultivating a positive viewpoint.

Hilkka Soininen

Hilkka Soininen

Likewise, individuals with the highest cynical distrust measured by Cook-Medley Hostility Scale had higher risk of dementia after adjusting for confounding factors including socioeconomic position, lifestyle, alcohol use, and health status, found Neuvonen’s team.

Financial, physical, and cognitive well-being can be enhanced by cultivating optimism and trust and reducing cynicism.

Higher “Purpose in Life” Reduces Adverse Health Outcomes

Lei Yu

Lei Yu

Purpose in Life – the sense that life has meaning and goal direction – is associated with reduced risks of adverse health outcomes including stroke, according to Rush University Medical Center’s Lei Yu, Patricia A. Boyle, Robert S. Wilson, Julie A. Schneider, and David A. Bennett collaborating with Steven R. Levine of SUNY Downstate Medical Center.

Patricia A. Boyle

Patricia A. Boyle

Older people with a greater sense of purpose are less likely to develop other undesirable health conditions including:

Robert S. Wilson

Robert S. Wilson

Yu’s team analyzed autopsy results on 453 older adults enrolled in the Rush Memory and Aging Project.

All participants underwent annual physical and psychological evaluations, including a standard assessment of Purpose in Life, and were followed until they died, at an average age of 90.
None of the participants had dementia when they entered the study, but 114 people had suffered a stroke.

Eric S. Kim

Eric S. Kim

Yu’s team extended earlier work by University of Michigan’s Eric S. Kim, Jennifer K. Sun, Nansook Park, and Christopher Peterson, demonstrating that Purpose in Life is associated with a reduced risk of clinical strokes in a group of participants aged 53 to 105 years.

This difference suggests that purpose in life is protective for silent infarcts, as well as clinical stroke.

Jennifer Sun

Jennifer Sun

At autopsy, Yu’s group observed macroscopic infarctions, areas of stroke damage visible to the naked eye, among 154 participants and microinfarcts, areas of damage visible with a microscope, among another 128.

Purpose in Life was judged annually using a modified 10-item measure derived from University of Wisconsin’s Carol D. Ryff and Corey Lee Keyes’ scales of Psychological Well-being.

Carol D. Ryff

Carol D. Ryff

Higher scores indicating a greater purpose, and every one-point increase, the likelihood of having one or more macroscopic infarctions decreased by about 50 percent.
In contrast, there was no link between purpose and microinfarcts.

These results persisted after adjusting for potentially confounding factors including vascular risk factors:

  • Body mass index,
  • History of smoking,
  • Diabetes mellitus,
  • Blood pressures.
    Corey Lee Keyes

    Corey Lee Keyes

    Other controlled factors include:

  • Optimism,
  • Childhood adverse experiences,
  • Loneliness,
  • Negative affect,
  • Physical activity,
  • Clinical stroke.Purpose in Life can predict later health status and outcomes, and is amenable to improvement by social participation with friends, community services, physical activity and health behavior modification.
    These positive lifestyle changes contribute to improved physical and mental health and enhanced quality of life throughout the lifespan.
