Anxious People More Apt to Make Bad Decisions

New brain evidence provides insight into why highly anxious people are worst at making decisions when things get unpredictable.

Highly anxious people have more trouble deciding how best to handle life’s uncertainties. They may even catastrophize, interpreting, say, a lovers’ tiff as a doomed relationship or a workplace change as a career threat.

In gauging people’s response to unpredictability, scientists at the University of California, Berkeley, and the University of Oxford found that people prone to high anxiety have a tougher time reading the environmental cues that could help them avoid a bad outcome.

Their findings, reported March 2 in the journal Nature Neuroscience, hint at a glitch in the brain’s higher-order decision-making circuitry that could eventually be targeted in the treatment of anxiety disorders, which affect some 40 million American adults.

“Our results show that anxiety may be linked to difficulty in using information about whether the situations we face daily, including relationship dynamics, are stable or not, and deciding how to react,” said study lead author Sonia Bishop, an assistant professor of psychology at UC Berkeley and principal investigator of the study.

“It’s a bit like being Alice in Wonderland, trying to work out if the same rules apply or if everything is different and if so, what choices you should make,” she added.

For example, a friend may suddenly lash out for no discernible reason. That friend’s behavior could reflect a typical variation in their day-to-day mood or interactions or, more dramatically, an underlying change in their relationship with you. The challenge for a person prone to anxiety is assessing the situation in context of what else has happened recently and responding appropriately.

Bishop and fellow researchers used decision-making tasks, behavioral and physiological measurements and computational models to gauge the probabilistic decision-making skills of 31 young and middle-aged adults whose baseline anxiety levels ranged from low to extreme.

Probabilistic decision-making requires using logic and probability to handle uncertain situations, drawing conclusions from past events to determine the best choice.

“An important skill in everyday decision-making is the ability to judge whether an unexpected bad outcome is a chance event or something likely to reoccur if the action that led to the outcome is repeated,” Bishop said.

The researchers’ measures also included eye-tracking to detect pupil dilation, an indicator that the brain has released norepinephrine, which helps send signals to multiple brain regions to increase alertness and readiness to act.

Participants were asked to play a computerized “two-armed bandit-style” game in which they repeatedly chose between two shapes, one of which, if selected, would deliver a mild to moderate electrical shock.

To avoid getting shocked, participants needed to keep track of the shape that most frequently delivered electrical jolts. During one part of the game, the shock-delivering shape did not change for a long stretch of time.

However, during another part of the game, it changed more frequently. Highly anxious people had more trouble than their less anxious counterparts adjusting to this and thus avoiding shocks.

“Their choices indicated they were worse at figuring out whether they were in a stable or erratic environment and using this to make the best choices possible,” Bishop said.

Also weaker in highly anxious participants was their pupil response to receiving a shock (or not) during the erratic phase of the game.

Typically, our pupils dilate when we take in new information, and this dilation increases in volatile environments. Smaller pupils suggested a failure to process the rapidly changing information that was more prevalent during the erratic phase of the game.

“Our findings help explain why anxious individuals may find decision-making under uncertainty hard as they struggle to pick up on clues as to whether they are in a stable or changing situation,” Bishop said.

In addition to Bishop, co-authors and researchers on the study were Timothy Behrens, Michael Browning, Gerard Jocham and Jill O’Reilly at the University of Oxford in England.

The study was funded by grants from the European Research Council and the National Institutes of Health.

Protesters Gather in Oakland, Other City Halls, to Halt Encampment Sweeps

The coordinated protests on Tuesday in San Francisco, Oakland, Vallejo, Fresno, Los Angeles and Seattle, were hosted by Poor Magazine and Wood Street Commons, calling on cities to halt the sweeps and focus instead on building more housing.

Houseless rights advocates gathered in Oakland, San Francisco, Los Angeles, and other city halls across California and Washington state this week protesting increased sweeps that followed a U.S. Supreme Court decision over the summer.

“What we’re dealing with right now is a way to criminalize people who are dealing with poverty, who are not able to afford rent,” said rights advocate Junebug Kealoh, outside San Francisco City Hall.

“When someone is constantly swept, they are just shuffled and things get taken — it’s hard to stay on top of anything,” said Kealoh.

Local houseless advocates include Victoria King, who is a member of the coordinating committee of the California Poor People’s Campaign. She and Dr. Monica Cross co-chair the Laney Poor People’s Campaign.

The demonstrations came after a June Supreme Court ruling expanded local governments’ authority to fine and jail people for sleeping outside, even if no shelter is available. Gov. Gavin Newsom in California followed up with an order directing state agencies to crack down on encampments and urging local governments to do the same.

Fresno, Berkeley and a host of other cities implemented new rules, making it easier for local governments to clear sidewalk camps. In other cities, such as San Francisco, officials more aggressively enforced anti-camping laws already on the books.

Special to the Post

Harvey Knight, Jr., “Pops” to so many young men from Oakland, passed away at 82 on Dec. 5. Harvey was married to Brenda Knight, founder of Ladies In Red, for 51 years.

He was born on April 6, 1942, in Laurel, Mississippi.

After completing high school, Harvey moved to Oakland, California, to live with his father’s sister. He knew this would become his home. He loved the Bay Area for the sports it offered him as a basketball, baseball, and football fan.

He worked for UC Berkeley for over 43 years and part-time for the Oakland Coliseum for approximately 15 years as a security guard, where he could be close to his favorite pastime.

After establishing himself with jobs and his place to live, he knew something was missing. He found the love of his life, married her, and knew his life was complete.

Three sons were born to their union: Leonard, Harvey III, and Michael. He and his sons enjoyed the life of sports by going to the games and later supporting them in baseball at school and through Babe Ruth Baseball. His love of sports was passed on to his sons. All three played baseball while attending college.

Harvey was a soft-spoken man who provided life gems to many young boys playing baseball with his sons. Many of them would end up at the Knight family table for dinner or to listen to the man they all called ‘Pops.’

Harvey loved to travel and take in the history he experienced on his many trips with his wife, Brenda, and the organization she founded, Ladies In Red. Although Harvey did not like the color red, he enjoyed the travel provided throughout the United States. He often researched to provide his wife with information to assist her in planning the trips.

His favorite trip was to Selma, Alabama, where he learned so much about Selma’s involvement in the Civil Rights Movement.

In lieu of flowers, please consider a donation in the name of Harvey Knight, to Foot Soldiers Park in Selma, Alabama. Go online to: footsoldierspark.org or mail to: Foot Soldiers Park INC, 1018 Water Avenue, Selma. AL 36701.

He leaves to mourn his passing, his wife Brenda; sons; Leonard, Harvey III and Michael; eight grandchildren, two great-grandchildren and a host of relatives and friends.

A Student-Run Group Is Providing Critical Support Services to Underserved Residents

During his three years volunteering at the program, Resource Director Zain Shabbir, says he noticed that many of the people who come in do not know how to navigate social services support systems, particularly online. This knowledge deficit, Shabbir says, is due to age or limited exposure to technology.

Resource Director Zain Shabbir is a jack-of-all-trades at the Suitcase Clinic, a student-run resource center that provides health and other services to underserved residents of Berkeley and surrounding areas.

Shabbir was once a clinic director. Now, he manages the General Clinic, floating around when case managers need assistance. And he has big plans for a new initiative.

During his three years volunteering at the program, Shabbir says he noticed that many of the people who come in do not know how to navigate social services support systems, particularly online. This knowledge deficit, Shabbir says, is due to age or limited exposure to technology.

So, he teaches clients the basics of using email, writing in word documents, and backing up files to their phones.

Shabbir shared a story about an interaction he had with a woman who came in seeking help to create a template to message property owners and realtors as she was seeking housing. Until that point, the woman was composing separate messages to each listing she was interested in, and that process was taking up too much of her time. With Shabbir’s help, she created a standard template she could modify and use for each housing inquiry or application.

He’s also hoping to use the technology to help people create resumes to find jobs.

“[The intent] is to help people find work in the city or wherever they live — or help them find housing. As most are probably aware, the two really go together because for housing, you need income verification, and for a job you need housing,” Shabbir said.

Having a warm place to go and a hot meal may seem basic buy it is critical for people who are struggling, clinic leaders say.

Mark, a frequent attendee of the Tuesday clinic, told the Oakland Post that he’s been receiving services from the program for nearly 25 years.

Mark said he was able to receive a referral to dental care through the Clinic, which he’s been using for about 20 years now. He also utilized the chiropractor, a service that is no longer offered, for pain and aches he acquired over the years.

Many program participants say they visit the clinic now for services provided by Berkeley medical students, who rely on osteopathic care rather than traditional methods. Osteopathic medicine is a medical philosophy and practice that focuses on the whole person, rather than just symptoms.

Executive director Nilo Golchini said that many clinic patients tend to appreciate and trust this type of medicine over mainstream practices because of sub-standard care they have received in the past because they are homeless or poor.

Acupuncture is also an extremely popular station at the Clinic as well, with participants saying it “soothes and calms” them.

Attendees of the clinic are generally in happy spirits throughout the hours they’re able to interact with fellow residents. Some even participate in arts and crafts, moving from table to show their friends their new creations.

“It’s a program that’s going strong,” said Golchini. “There’s a space for everyone” who wants to volunteer or receive services, and they’ll keep going as long as the community needs it.

The Suitcase General Clinic is open every Tuesday from 6:30 to 9:30pm. Women’s and Youth Clinics are held every Monday from 6 to 9pm.
