OF WEALTH AND DEATH: MATERIALISM, MORTALITY SALIENCE, AND CONSUMPTION BEHAVIOR (2002) Author Name: Kasser & Sheldon Background: - humantisitc & terror-management theories of materialism - terror management theory: “in order to cope with the overwhelming anxiety resulting from the realization of one’s inevitable demise, people believe in cultural worldviews that help them feel that they have meaningful lives and are worthy members of their culture” Hypothesis: They predicted that those who wrote about death would be more materialistic. They thought that those people experience more anxiety so they consume more resources in an attempt to have a more meaningful life. Main Structure: - Study 1: Participants were asked to either write about death or a neutral condition (music) to inflict “anxiety” and then asked to describe their financial expectations for themselves within the next 15 years. - Study 2: Had a similar construct in terms of what the participants were asked to write about. But the assessment included having participants participate in a forest-management game to measure fear and greed. Methods: - 60 undergraduate students (21 male and 39 female) were offered extra credit to complete a survey packet. - Subjects wrote down 6 personal strivings they were focused on and used a 9-point scale to rate how those strivings might help them get to 6 possible futures: self-acceptance/personal growth, affiliation, community feeling, (3 intrinsic) an attractive appearance, social recognition, and financial success (3 extrinsic). - A relative extrinsic orientation score was computed for each subject by subtracting the ratings for the three intrinsic possible futures from the ratings of the three extrinsic possible futures.” Higher scores indicated greater material focus. IV: topic of the writing (death or neutral) DV: future financial expectations and consumption ratings Results: showed that the feelings of insecurity produced by thoughts of death can produce materialistic behavior, but that there is only correlational evidence for this. - Those in study 1 who wrote about more neutral conditions were found to have higher expectations for themselves in 15 years - Those in study 2 who wrote about death were more “greedy” in their consumption ratings.

Answer 2

- more than one independent variable a. not just more than one level of one IV) - use this notion a. 2 x 3 Factorial Matrix b. Read Two by Three" c. Use ANOVA to look for significant differences - can't use t-tests because

Answer 3

This 2 x 3 matrix has 6 possible conditions (notice 2 x 3 = 6) - A 4 x 2 x 3 matrix would have 24 conditions - Each IV is called a factor with x number of levels

Answer 4

In summary, a 2 x 3 factorial matrix has 2 independent variables AKA factors - Factor A has two levels - Factor B has three levels Combined, there are 6 possible conditions

Answer 5

Interpreting the results - Main effects - when the row means or column means are not equal (could be both, could be neither, could be either one) - ANOVA needed to test for significant differences Main Effects - Column means: 10.67, 8.67 Main effect for GENDER --> column means are not equal. Men & women differ on their average scores. - Row means: 4, 10, 15 Main effect for THREAT LEVEL --> row means are not equal. Scores differ by condition. - Both factors contain a main effect

Answer 6

This can get complicated quickly! Making sense of interactions more complex than three-way interactions can be daunting!

Answer 7

Listening to Mozart Does Not Enhance Backwards Digit Span Performance (1997) Author Name: Setlle, Ball, & Runk Background: Rauscher, Shaw, and Ky (1993) reported that participants in the study increased their mean spatial reasoning scores by 8 or 9 IQ points after listening to Mozart’s music for 10 minutes. - This was labeled the “Mozart Effect,” and was found to be temporary, only lasting for 10-15 minutes. - Attempts by Kenealy and Monsef(1994), Newman et al.(1995), Stough et al.(1994), and Carstens et al.(1995) were all unsuccessful in replicating the original findings. - Rauscher, Shaw, and Ky (1995) reported a replication of the Mozart effect, specifying that an appropriate task should involve spatial recognition, as well as incorporating spatial and temporal transfusions. Hypothesis: examine whether a Mozart effect would be produced following the procedure of Rauscher et al. (1993). Main Structure: - Used backwards digit span performance as the dependent variable, adhering to Rauscher’s specification that the task should involve spatial and temporal transformations. - The study consisted of a within-subjects design with 2 independent variables and a control condition. Methods - Thirty-six Euro-American university students (28 Women and 8 men) from a psychology course who volunteered and received course credit for participating. - Two stimulus tapes of a 10 minute duration were used: --> Mozart Sonata for Two Pianos in D Major (K448) --> Recording of a gentle rainstorm (“Spring Showers”) - Sequences of digits were recorded on separate tapes for the digit span task. - Participants were told the experiment concerned the effect of relaxation on recall and were sat in a comfortable recliner chair. - All participants listened to the Mozart tape, the rainstorm tape, and sat quietly after being told to “relax,” with the order of each stimulus being counterbalanced using a Latin square design. - After exposure to the stimulus condition participants listened to three nine-digit sequences and attempted to repeat the sequence in reverse order after each one. - Correct recall was defined as the correct digit in the correct serial location. IV: Type of music listed to (Mozart or spring showers) DV: the sum of number of digits correctly recalled in reverse order. Results - No difference overall in mean recall as a function of preceding stimulus condition. - Lack of differences not due to unsystematic variability. - Clear practice effect was observed. - Mean recall improved by additional experience with the task. - no significant differences among treatments - Exposure to Mozart’s music was not followed by an enhancement in performance on the backwards digit span task.

Beyond Simple Pessimism: Effects of Sadness and Anger on Social Perception (1993) Author Name: Keltner, Ellsworth & Edwards Background: - General positive and negative moods shown to influence various judgments. - (see Forgas & Bower 1987) --> Personal Efficacy --> TAT Scores --> Social Performance - However, not much research on specific effects that diff. emotions have on judgments Hypothesis Overall: - Empirical Question: Do different negative emotions influence judgments in more specific ways than creating a general pessimism? - Hypothesis: Sadness and anger will exert different influences on causal judgments. Effects of Sadness & Anger on Judgements of the Probability of Future Events - Experiment #1: Sad participants will perceive situationally caused events as more likely than angry participants. Angry participants will perceive events caused by humans as more likely than sad participants. Effects of Sadness & Anger on Judgements on Causal Judgments of an Ambiguous Situation - Experiment #2: Sad participants will emphasize the situation as being the cause of an ambiguous situation. Angry participants will emphasize other people’s actions as being the cause of an ambiguous event. Sad participants will perceive an ambiguous situation as hopeless. Angry participants will perceive others’ actions as unfair in an ambiguous situation. Main Structure - 48 college students from intro psych class at Stanford - 2x2 Factorial Design Students were randomly assigned to 1 of 4 conditions Methods - experiment #1: --> Participant Instructions: the survey will investigate the way people imagine hypothetical scenarios. --> Emotion Induction (sadness or anger) --> Life Events Questionnaire - experiment #2: --> Same false instructions as Exp. #1 --> Emotion Induction - same as Exp #1** --> Target Situation --> Questionnaire (rating on 1-9 scale) a. Target situation’s causes b. Situation’s hopelessness c. Fairness of others’ actions d. Your emotions (sad, angry, guilty, contemptuous, happy, proud) IV: were induced sadness and induced anger DV: Rated probability 1-10 of life events Results - statistically significant differences - 3 way interaction between Emotion, Agency of Judgement & Form Type was significant (partially confirms hypothesis) - Emotion and Judgement Interaction = Not significant (doesn’t support hypothesis) - Sad participants were more likely than angry participants to attribute the mishap to situational forces. Angry participants were more likely than sad ones to attribute it to other people. - Sad participants perceived the situation to be more hopeless than angry participants. Angry participants perceived other people as less fair than angry participants. Overall: - Researchers found that different negative emotions would result in different interpretations of events. - Sadness → More situational agency Anger → More human agency Used different manipulations & measures to confirm this Sadness and anger BOTH influence judgments of… - Probability of future events caused by humans or situational forces - Responsibility for an embarrassing social situation - The sources of one’s own life circumstances and future problems. In real life.. - Emotions are more salient → have greater effect (most likely) *experiments #3-5 replicated results of experiment 1 while adjusting certain conditions and the results supported the original hypothesis Critiques *see image*

Answer 9

One main effect or Two main effects or No main effects And Interaction or No interaction

Answer 10

One main effect: color vs Black & White If one is always higher than the other, this is one main effect AND no interaction (parallel) - you don't say it depends (doesn't depend)

Answer 11

one main effect AND no interaction - it doesn't depend

Answer 12

Two main effects - color (one is higher & one is lower) - hands on (one is higher & one is lower) NO interaction (they are parallel & don't cross)

Answer 13

No main effect AND no interactions

Answer 14

main effect for color vs black & white (no effect for hands on vs cognitive) AND interaction - the means are not different (hands on vs cognitive) - the means are different (for color between ) (this is why on main effect) FIX BASED ON NEXT card - they will eventually cross (interaction) a. it depends, color is better for hands on topic than black and white is for hands on, there is no difference for cognitive topic

Answer 15

main effect for hands on vs. cognitive only, and an interaction - mean of color fr hands on vs cognitive meets in middlke - mean of balck and white is in middle for hands on vs cogniitve (this is why no main effect for color)

Answer 16

interaction and two main effects it depends, if you teach a hand on (color), if teaching cog (doesn't matter much)

Answer 17

interaction BUT no main effect it depends, on if you teaching hands on ( you should use black and white) when teaching cognitive (use color)

Answer 18

an interaction: effective for women over 40 when combined w exercise. no effect for age or gender. NOTE: *Sometimes the interactions are more informative than the main effects*

Answer 19

some questions have comfortability as a high number, and some have comfortability as a lower number - be careful when analyzing data (most make sure its all correlated in the right way)

Answer 20

Sampling Issues in survey research: biased vs representative samples - non-probability vs probability samples - self-selection bias --> e.g election of 1936 Surveys vs Psychological Assessment: - attitudes, opinions, beliefs, projected behaviors - VS. - psychological functioning

Answer 21

types of survey questions or statement: - open-ended vs. closed questions - "most important problem" question - use of Likert scales a. avoid response bias (response acquiescense) - assessing memory and knowledge a. moderate us of DK alternative Adding demographic information - basic identifying data (e.g age, income) - place at end of survey A key problem: Survey wording - avoid ambiguity (pilot study helps) - don't ask for two things in one question a. double-barreled questions - avoid biased and leading questions

Answer 22

in person interview surveys - positives --> in-person, comprehensive, follow ups possible - negatives --> representative samples, cost, logistics, interviewer bias mailed surveys - positives --> low cost ease of sampling - negatives --> phone surveys - positives --> cost, efficiency - negative --> must be brief, response rate electronic surveys - positives --> cost, efficiency - negative --> sampling issues, ethics - sugging (can i sell you something) (and frugging: fundraising) *not research* Ethical considerations - using and abusing survey data

Answer 23

Women, Men, and Condoms Attitudes and Experiences of Heterosexual College Students (1992) Author Name: Campbell, Peplau and DeBro (1992) Background - AIDS became the leading cause of death for all Americans ages 25-44 years old in the mid 1990’s. - Only 13% of sexually active college students always use a condom during vaginal intercourse and 66% had never used a condom. (Baldwin 1988). - Research on birth control has found that women rate both ease and use and familiarity as more important characteristics of condom usage than do men. Hypothesis - Men and women would differ on each of the four domains of attitudes about condoms (comfort and convenience, efficacy, interpersonal, sexual sensation). Main Structure Researchers surveyed 393 undergraduate students (213 women, 180 men) aged 18-24 at UCLA about attitudes and experiences involving condom use in four different categories. Methods - College students completed a 16 page paper questionnaire. - Included: Demographic characteristics Dating experience Sexual history - Taken in separate room, completed questionnaires placed in plain envelopes and returned to researchers. IV: man or woman DV: attitudes about condom use Results They found that students were generally favorable towards condom use, and that a positive attitude towards condoms was related to intent to use condoms in the future. They also reported some slight gender differences: women had a more positive attitude towards condoms, while men believed them more effective. Critiques *see image*

A THREATENING INTELLECTUAL ENVIRONMENT: Why Females Are Susceptible to Experiencing Problem-Solving Deficits in the Presence of Males (2002) Author Name: Inzlicht & Ben-Zeev (2000) Background - Stereotype Threat: When placed in the minority and asked to perform in a stereotyped domain, people are reminded of the stereotype that negatively impacts their group’s image Hypothesis: Female performance deficits that occured would only happen in the stereotyped domain - Tokenism: Regardless of which domain people are in, they face the pressure of being responsible to represent members of their group in a positive light due to self-consciousness created by the ‘token status’ - Threatening Intellectual Environment: any environment that can set the presence of threatening effects of gender stereotypes in motion - Distinctiveness Theory: Having a minority status can cause a sense of group identity which can then cause them to become more aware of their identity as a minority in the group (example: females increasingly outnumbered by males become more aware of their status as a female) Hypothesis: Female performance deficits that occured would occur in both the stereotyped and non stereotyped domains Main Structure & Methods experiment #1: Was designed to look at whether females placed in a minority condition (where they are outnumbered by males) experience declines in performance in comparison to females who are placed in a same-sex condition (where they are only with other females) in order to test the stereotype threat and tokenism hypotheses experiment #2: Participants were both male and female Participants completed a math test only IV: presence of males or just females DV: performance on tests Results Experiment 1: Findings showed that when females were placed in a threatening intellectual environment, they tended to demonstrate deficits in mathematical performance Experiment 2: Findings showed that results replicated, male participants were not affected by sex-composition manipulation, and that females scored the lowest in minority condition, middle in mixed-sex condition, and highest in same-sex condition Critiques *see image*

Answer 25

Varieties of observational research - naturalistic observation: describing behaviors in natural settings a. observer is unobtrusive, or b. habituation assumed - (e.g, with animal observations (Goodall example) c. Examples: - Snack selection at movie theaters - Gender differences in behaviors at a bar - Helping behaviors in a preschool setting - Random Family: Love, Drugs, Trouble, and Coming of Age in the Bronx, Adrian Nicole LeBlanc - Participant observation a. experimenter joins group being observed b. Ex. Fetsinger's study of a cult - data recording issues - Ethical issues and reactivity --> Experimenters changing the group

Answer 26

absence of control - but falsification of strong claims possible observer bias - use of behavior checklists - interobserver reliability - time and event sampling Participant - Use of unobtrusive measures helps Ethics - Consent and privacy issues (Box 10.2)

Answer 27

- observational study - naturalistic observation in a science museum - consent obtained (unusual in observational research) - event sampling used - results --> parents (Dads and Moms) explain science concepts more to their sons than to their daughters

Answer 28

- "covert" participant observation at a homeless shelter a. Discovering “identity maintenance strategies” in homeless individuals b. Experimenter served as a volunteer at homeless shelter --> She had already done so for 2 years prior c. Experimenter kept a journal of her observations for 3 months d. Results --> how individuals interacted with others and how they thought of themselves depended upon how long they were homeless

Answer 29

analyzing qualitive data from non-experimental designs - method of identifying patterns of responses - or themes- in within qualitative data - Six steps: 1. get familair with the data 2. code 3. search for themes 4. review themes 5. define and name themes 6. write report

Answer 30

- data previously collected for some other purpose - often undergoes content analysis: A procedure for systematically categorizing the content of the behavior (often verbal) being recorded - Susceptible to missing data and bias, but no reactivity - Research Example 31 a. IV --> patient recovering room --> Experimental --> pleasant view of park --> Nonequivalent control --> brick wall b. DV --> recovery & other factors (better for room with a view)

Answer 31

factor analysis - identifies what tests/items cluster to form factors Meta-analysis - a special case of archival research - analysis of eefcet sizes across multiple studies all related to a simialr topic - two main questiuons can b answrred a. is the effect consistent across studies? b. if the effect is consistent, what is the effect size

Answer 32

Does Television Violence Cause Aggression? (1972) Author Name: Eron, Lefkowitz, Huesmann & Walder Background - Television has become widely available only within the last ~20 years, and many newer programs, both intended and unintended for children, contain violent imagery -Recent research has shown that children can replicate violent behavior that is shown to them on film, particularly when that behavior is conveyed through cartoons (Bandura, Ross & Ross 1963) Hypothesis Young adults aggressiveness is positively related to preference for violent TV when they were 8-9 years old, and this preference is the cause of aggression Main Structure - Longitudinal - A sample of 875 third graders (aged 8-9) was evaluated in 1960, and a reduced pool of 427 teenagers (aged 18-19) from the original sample was again evaluated in 1970: of the second pool, 211 were male and 216 were female Methods - Aggression” was measured by asking the students “Guess Who?” style questions about their peers, featuring 10 categories related to who was most likely to commit a variety of aggressive actions. Some examples include “Who starts a fight over nothing?”, “Who says mean things?”, etc. -When asked again after 10 years, the method was the same but questions were modified for the age group, now asking questions relating to work, relationships, etc. -Furthermore, when participants were interviewed again at age 18-19, the authors now included a self-reported level of aggressiveness, proxied by how often they participated in antisocial behavior IV: preference for violent television DV: aggression Results - For boys, there was a positive relationship between a preference for violent television programs in the third grade and peer-rated level of aggressiveness both at ages 8-9 and 18-19 -Alternatively, for girls, there was no significant relationship LATER: The results show a positive correlation between preference for violent television in the third grade (TVVL3) and peer-rated level of aggressiveness in both age groups (AGG3, AGG13). However, it is important to note that this relationship does exist at a fairly weak confidence level. Critiques direct causality can not be obtained from a correlational study

The Psychological Consequences of Conflict: The Role of Socioecomonic Factors in Leading to Psychological Illness in Refugees and Torture Survivors (2002) Author Name: Ottalah and Langholtz (2002) Background - Civilians used to be neutral bystanders in terms of war but now they have become targets of violence. - 90% of war casualties are civilians, compared to only 5% in World War I - Entire populations often suffer multiple traumas of war which appears to have long-term psychological consequences Hypothesis: Documentation suggests that conflict trauma significantly increases the incidence of psychological symptoms and illness This article explores the role of refugee trauma and conflict trauma play in inducing mental illness. Main Structure Inability to conduct an experiment in a lab, difficulty in finding participants willing to discuss their experiences, and a lack of prior mental health records in war-torn countries led the authors to conduct a literature review and a descriptive statistics analysis IV: socioeconomic varibles DV: psychological outcomes Results - Exile and torture lead to increased incidence of depression, anxiety, and PTSD - Pre-trauma characteristics and post-trauma socioeconomic factors play a significant part in determining whether an individual who suffers these tragedies will develop mental illness - Mental illnesses can lead to functional disability Critiques *see image*
