Best of Fall 2008

2009-01-15T21:52:00.005-05:00

Hello J,

It was great to have you as a Professor this semester. I am writing to see if you can please do the average of my quiz in order to have the grades of those two quiz that I missed. This has been a tough semester for me since I had to recover for two hemorroidals surgery that I had combine some other healths ploblem. I am a premed student and I am worrying about bringing my GPA down. Other professors have understood my situation in doing so. I don't even think that I did well on the final yesterday since I had a chemistry exam the same morning and another psyc class exam is coming thursday. So I have been making up my exams and doing finals at the same time, being a student yourself I guess you know how it looks like. I am really afraid of having a c in this class and I think you can understand my situation well than someone who has a career professor since you are a student yourself. I wish you well and I hope you help me solve this matter.
With much appreciation,
B

Um... other professors have given you credit for assignments that you didn't turn in just because you're premed? If you really did worry about your GPA, you wouldn't have arrived 20 minutes late to miss those two quizzes in the first place. I even allowed you to make them both up on the make-up date, but you showed up late again and missed the make-up session. Have fun in the Bahamas, B.

Hi j

I was wondering If I got over 90?
I had fun throughout the semester and you have a bright future as an instructor since you are still young. You were fair on grading and helpful. Well I did my part and studied hard but I never get multiple choice questions entirely right even though I eliminate at least two wrong out of four. My only concern is that my cousins are paying my tuition since my father left us. I mean the bottom line is I can not get a C and so far suprisingly my only C seems like from your class so thanks for being kind it was my failure should have done better on the first mid term.

Best Regards
k

Thanks for predicting my future, K, but I'm not going to do a damn thing about all the quizzes you failed/missed and the D you got on your first exam, although it's nice that you're finally taking responsibility for your grade. I hope you realize now that a full semester of antagonizing the instructor for your pitiful performance will only bring on the smackdown. I'm glad you're so concerned about your cousins; maybe next time you won't squander their tuition dollars.

Hello J, Thanks for a great semester. I found your class to be very informative, However, in light of last exam I feel I may be in jepordy of fialing your class. Is anything can do to come out with at least C-. it has been a hard semester for me. alot personal issues going on outside of class. I will use this break to refocus myself.

Thanks, T

This was was pretty painful because you're such a nice guy, T. But when you hand in blank sheets of paper as your essay responses, there's not much I can do to help. I did change my grading scale around to turn that 53% into a D instead of an F. Happy holidays!

Passing Prop 8: Divided reactions from gays

2008-11-09T20:41:00.017-05:00

Over the last few days, we've seen a sudden surge in rallies and calls to protest the LDS church. Sites such as Mormons Stole Our Rights are popping up as well as calls to boycott Utah. How does a community targeted by discrimination respond to its attackers? Online discussion forums show a clear difference in opinion as to how we should approach the issue:

Enough with the damn Mormon bashing. This isn't some hate pissing match. Yes, they represented a disproportionate amount of the money behind Prop 8. They're organized. They have their shit together. Get over it. This shouldn't be about the victory of Yes on Prop 8, etc. This should be about the failure of the gay community to connect with voters. 52% of the California population isn't LDS, after all.

There is not a snowball's chance in hell that I will stop mormon bashing. They started this in 98 when they went all anti-gay in Hawaii. Fuck them and the polygamist horse they rode in on.

They should not have tax exempt status if they plan on lobbying on state or federal level. Freedom of religion also means freedom from religion. Their argument comes from a religious point of view.

The problem isn't JUST the Mormon Church. The problem that we're facing is more complex than that. We're the new black when it comes to hate . Gays are the cause to get behind if you're a Conservative an/or a bigot and you're pissed at the world. Because we're the only game left in Town. These people who voted for this ballot measure knew what they were doing. They knew that gay men and women are and will never be any real threat to them. They knew that they had to rally around lies to support it. But will they come out and say they supported it? Hell No they won't because they Know what a heinous piece of crap they voted for. That's why it's time to expose all of them. From the ones who paid money for the cause to every one who went into that voting booth and pulled that metaphorical lever. Time to turn on the kitchen light and let the cockroaches run for cover.

This whole thing has gone a little too far, in my opinion. Everyone wants someone to blame. The Mormons, the Blacks, the Latinos, the Gays (for being complacent). Part of my opinion on not hating on others the way we have been hated on, is not to stoop to their level so much so that we become hypocritical. Just because one group does something that is negative and wrong, doesn't mean we should do the same thing back.

I hate to tell you this, stud, but the LDS Church isn't just a bunch of pushovers. They have deliberately, with great organization and strategy, done evil to us, and they deserve to suffer for it. Also, you can't ignore the fact that they supplied the vast majority of funding to propagate these lies. NOT ALL Mormons. I have lots of Mormon friends, I don't hate Mormons. But their church and their organization is going down, period. I agree-- my Mormon friends are some of the best, most moral, family-oriented people I know. But the LDS church and its entire hiearchy deserves to burn.

Many gays and lesbians (myself included) felt bittersweet towards the simultaneous victory of Barack Obama and the passing of Prop 8. How does a nation so seemingly in favor of progressive solutions pass a proposition that pushes the LGBT movement backwards (especially in the largest blue state)? Ultimately, it probably boils down to a difference in strategy.

Emerging field: neuromarketing

2008-11-06T05:01:00.009-05:00

Forget surveys and focus groups. Verbalized opinions are confounded by cognitive biases that may hide how consumers might "really" feel about a product. At least this is what the emerging field of neuromarketing wants you to think. The potential for exploitation has even generated a Commercial Alert.

Is neuroimaging an effective tool for designing popular consumer products? The basic idea is simple: show participants a bunch of stimuli and record brain activity indicative of positive affect or feelings of reward. Those that generate the best responsiveness can become prototypes for future products. But there can be complications depending on the type of product being created and the stimuli being presented, especially when dealing with a daunting combinational space (see Goebel, 2008 for more).

But putting experimental design aside, isn't there something wrong with assuming that positive affect is the best indicator of a "good" product? Eliciting other emotions, such as sadness, can be just as "good" if not better.

Obama has a Kenyan aunt living illegally in Boston. Obviously he's siding with immigration law, but this story just makes me feel so sad. Where is Antigone when you need her? Who is going to champion the laws of the oikos?

Left-wing brain vs. right-wing brain

When Fox News is bashing McCain, you know something's wrong. Looks like those flip-flop economic policies haven't been going so well with the conservative base. But hey, what do you expect from a system-shaking, bipartisan MAVERICK? Unfortunately for McCain, looks like no one told him what psychologists have know for a few years now: conservatives don't like change!

In a short and sweet experiment, Amodio and colleagues (2007) showed that liberals were more responsive to ambiguity and novelty, whereas conservatives preferred structure and persistence. Participants performed a Go/No-Go task (they had to press a key when "M" appeared on a screen, but had to withhold their response when a random "W" appeared), while error-related negativity (ERN) amplitudes were recorded.

Larger ERN = greater accuracy to the No-Go or "change" trials (in this case, the Ws)

Increased liberalism was correlated with larger ERNs, meaning liberals responded better to change than conservatives:

Jonathan Haidt also has a great talk on the psychology of liberalism and conservatism. He elaborates on people's affinity/aversion to change by examining personality factors and moral values. Watch it:

Warm drink, warm thoughts?

2008-10-31T23:34:00.019-04:00

Ever since Harry Harlow's studies on contact comfort, psychologists have known that touching warm cuddly things can generate warm cuddly feelings (I recommend the n.a.p Cuddle Blanket from Brookstone... totally worth it). Although he was primarily interested in mother-infant attachment, it looks like the ghost of Harlow has been resurrected in Science this month in a study of physical warmth and likability judgment:

Experiencing Physical Warmth Promotes Interpersonal Warmth

Lawrence E. Williams and John A. Bargh
"Warmth" is the most powerful personality trait in social judgment,and attachment theorists have stressed the importance of warmphysical contact with caregivers during infancy for healthyrelationships in adulthood. Intriguingly, recent research inhumans points to the involvement of the insula in the processingof both physical temperature and interpersonal warmth (trust)information. Accordingly, we hypothesized that experiences ofphysical warmth (or coldness) would increase feelings of interpersonalwarmth (or coldness), without the person's awareness of thisinfluence. In study 1, participants who briefly held a cup ofhot (versus iced) coffee judged a target person as having a"warmer" personality (generous, caring); in study 2, participants holding a hot (versus cold) therapeutic pad were more likelyto choose a gift for a friend instead of for themselves.

This comes alongside another study published in Psychological Science (also this month) that showed the causal direction going the other way as well (i.e. feeling sad affects judgment of room temperature):

Cold and Lonely: Does Social Exclusion Literally Feel Cold?

Chen-Bo Zhong and Geoffrey J. Leonardelli
Metaphors such as icy stare depict social exclusion using cold-related concepts; they are not to be taken literally and certainly do not imply reduced temperature. Two experiments, however, revealed that social exclusion literally feels cold. Experiment 1 found that participants who recalled a social exclusion experience gave lower estimates of room temperature than did participants who recalled an inclusion experience. In Experiment 2, social exclusion was directly induced through an on-line virtual interaction, and participants who were excluded reported greater desire for warm food and drink than did participants who were included. These findings are consistent with the embodied view of cognition and support the notion that social perception involves physical and perceptual content. The psychological experience of coldness not only aids understanding of social interaction, but also is an integral part of the experience of social exclusion.

No wonder winter here is so miserable except when I have warm (and free) psych department coffee.

Zimbardo vs. Rowling on Heroism

2008-10-29T21:00:00.017-04:00

Everyone should watch this talk:

Philip Zimbardo, famous for his 1971 Stanford Prison Experiment, discusses factors that induce ordinary people to perform extraordinary acts of cruelty. For decades, social psychologists have known about the influence of situational factors in fostering human cruelty and indifference (the banality of evil). But as a new contribution, Zimbardo also discusses the banality of heroism as a counterpoint to blind obedience/indifference (i.e. how ordinary people can be trained to act heroically).

His hypotheses:

Classic childhood superheroes are ineffective models for real-life heroism because they have superpowers that are too far-removed from the ordinary person (i.e. it's difficult for ordinary individuals to relate to superheroes, so they classify heroic behavior as something they are not capable of performing).
By highlighting stories of ordinary people choosing to act heroically in extraordinary circumstances, we celebrate the ordinary hero and encourage all people to follow suit (see the story of Professor Liviu Librescu as an example).

But is it true that fantastical heroes don't inspire heroic action in everyday people? Absolutely not! Dumbledore's Army... er... Harry Potter Alliance to the rescue!! Here's a description from their site:

Did you ever wish that Harry Potter was real? Well it kind of is. After all, both our worlds face "dark and difficult times":

Genocide, Poverty, AIDS, and Global Warming are ignored by our media and governments the way Voldemort's return is ignored by the Ministry and Daily Prophet.
People are still discriminated against based on sexuality, race, class, gender, ethnicity, and religion just as the Wizarding World continues to discriminate against Centaurs, Giants, House Elves, Half-Bloods, Muggle borns, Squibs, and Muggles
Our governments continue to respond to terror by torturing prisoners (often without trial) just as Sirius Black was tortured by dementors with no trial
A Muggle Mindset pervades over our culture-a mindset that values being "perfectly normal, thank you very much" over being interesting, original, loving, and creative

Apparently, there's a chapter in Boston but looks like it's 100% Emerson students :(

Signal Detection FAIL

2008-10-29T17:31:00.006-04:00

The prospect of ongoing war in the Middle East has our military turning to drones or robotic agents to seek out insurgent leaders. As an undergrad in cognitive science, I remember professors and students (myself included) excited about the large-scale investment our government had put in signal detection for warfare. Sounded like a terrific idea at the time - less American troops put in harm's way. But at what cost?

In a recent attempt to kill a Taliban leader, an unmanned aircraft had a false alarm and fired missiles at a religious school in Pakistan, killing at least eight school children (see full article). Would a human pilot have been better?

Does my brain look gay?

2008-10-28T03:24:00.011-04:00

Earlier this year, an article (Savic & Lindstrom, 2008) came out in PNAS with some really compelling evidence that a) gay brains are different from straight brains, and b) those differences are not a result of learning. Why so much attention compared to past gay brain studies?

Past studies:
1. Cerebral (motor cortex & reward circuitry) responses to watching porn: gay men = straight women; straight men = gay women
2. Anterior hypothalamic activation when sniffing pheromones: gay men = straight women; straight men = gay women

Not very compelling since these were all perceptual tasks, and responses could have been due to either innateness or learning. So Savic and Lindstrom wanted to look at factors not directly associated with behavior: a) cerebral asymmetry and b) functional connectivity of left vs. right amygdalae.
The motivation for cerebral asymmetry came from other studies that showed:

Anterior commisure: gay men/straight women > straight men
Verbal tasks: gay men/straight women > straight men/gay women
Visuospatial tasks: gay men/straight women < straight men/gay women
Right-ear preference: gay men/straight women < straight men/gay women

The choice to compare left and right amygdalae was based on Larry Cahill’s work on sexual dimorphism in emotional memory.

What they found was that sexually dimorphic brain features differed within same-sex subjects depending on sexual orientation. Essentially, gay male brains (like straight female brains) did not show cerebral asymmetry while straight male brains (like gay female brains) had larger right hemispheric volume. The amygdala scans also showed that functional connectivity was more widespread from the left amygdala in gay men/straight women, and the right amygdala in straight men/gay women.

More acceptance for gays?

These findings have gotten a lot of attention because of their implications that homosexuality is innate. Is this really something that will bring gays wider acceptance?

My advisor, Dr. H, has an interesting take on this:

Many gays and lesbians have embraced the position that homosexuality is not a choice because they feel that less discrimination and prejudice will be forthcoming for something that is genetic, biological, or otherwise not a choice. But this is a fallacy. Why shouldn’t people’s lifestyle choices be just as respected as “choices” made by their DNA? This reminds us of what is called the “naturalistic fallacy”: Just because something occurs in nature (e.g., has a genetic component) doesn’t mean we should tolerate the expression of those behaviors. For example, criminality and sociopathy have a genetic component, yet we don’t tolerate these behaviors. Religious beliefs are often choices, yet we tolerate (and protect by law) religious diversity.

For a long time I’ve been undecided about the innateness of homosexuality because twin studies haven't held up the genetics argument and because there are incidences of situational homosexuality (gay prison sex). But in any case, why can’t we strive for acceptance even if it is a choice? Do we really believe that by demonstrating a biological origin of homosexuality that less prejudice will be forthcoming? What makes us think that we would find anymore acceptance than sociopaths, as Dr. H suggests? (For one thing, sociopaths are not law-abiding citizens and for another, I would like to think they are fewer in number.)

Until I took a job teaching social psychology this year, I was convinced that it wouldn’t really matter to the straight population whether being gay was biologically determined or not; we would still remain a persecuted minority. But the social psychologist, Elliot Aronson, (2008) has something to say in regards to the effect of an unchangeable status:

The psychology of inevitability can and does set up pressures to reduce prejudiced attitudes.

That is, the sooner individuals realize that interaction with a disliked group is inevitable and stable, the sooner prejudiced attitudes will begin to change. If homophobic individuals with gay family members/co-workers/friends/etc. realize that they will inevitably have to interact with a gay person and that sexual orientation cannot change, then they are presented with a state of cognitive dissonance: the behavior (interacting with a gay person) does not match up with the attitude (dislike of homosexuals). Thus, they can continue feeling angry or they can change their attitudes about homosexuals.

So according to Aronson, a biological cause of homosexuality will lead to more acceptance for individuals close to a gay person. But what about acceptance from the general population? Unlike race, sexual orientation can be hidden and gay men and women can go on living their lives fully integrated without ever revealing their sexual identity. Will continued media exposure be effective? Unfortunately, inevitability wasn’t built into the remote.
