Are they bothered? How the opportunity to damage a partner's reputation influences giving behavior in a trust game

Studies of reputation use in social interactions have indicated that when individuals can acquire a positive or negative reputation, they are motivated to act in a cooperative fashion. However, few researchers have examined how the opportunity to confer this reputation on a partner may influence an individual's behavior in a mixed-motive situation. In the present study, an experiment using a trust-game paradigm indicated that participants felt that they had more control over their partner's reputation when they could leave feedback regarding the outcome of their interaction with their partner. However, the participants would only donate a substantial portion of their initial endowment (i.e., over 50%) when they could leave feedback for a partner and when they felt that their partner was concerned about his or her own reputation. The author discusses these findings in regard to how they might apply to real-world reputation use and how possible future studies may further expand knowledge in this area.     

Musical preferences during and after relaxation and exercise

Effects of the listening context on responses to music largely have been neglected despite the prevalence of music listening in our everyday lives. This article reports 2 studies in which participants chose music of high or low arousal potential during (Experiment 1) or immediately after (Experiment 2) exercise or relaxation. In Experiment 1, participants preferred appropriate arousal-polarizing music over arousal-moderating music. In Experiment 2, participants preferred arousal-moderating music over arousal-polarizing music, such that their listening times contrasted clearly with those in the first study even though the same music and methods were used. Thus musical preferences interact with the listening situation, and participants' music selections represent an attempt to optimize their responses to that situation. When motivated to maintain a state of polarized arousal, listeners use music to achieve this; when they have no such goal, they use music to moderate arousal.     

Mental Depreciation and Marginal Decision Making

We propose that individuals practice “mental depreciation,” that is, they implicitly spread the fixed costs of their expenses over time or use. Two studies explore how people spread fixed costs on durable goods. A third study shows that depreciation can lead to two distinct errors in marginal decisions: First, people sometimes invest too much effort to get their money's worth from an expense (e.g., they may use a product a lot to spread the fixed expense across more uses). Second, people sometimes invest too little effort to get their money's worth: When people add a portion of the fixed cost to the current costs, their perceived marginal (i.e., incremental) costs exceed their true marginal costs. In response, they may stop investing because their perceived costs surpass the marginal benefits they are receiving. The latter effect is supported by two field studies that explore real board plan decisions by university students.     

Did the Chinese Have a Change of Heart?

In their "The Prevalence of Mind-Body Dualism in Early China," Slingerland and Chudek use a statistical analysis of the early Chinese corpus to argue for Weak Folk Dualism (WFD). We raise three methodological objections to their analysis. First, the change over time that they find is largely driven by genre. Second, the operationalization of WFD is potentially misleading. And, third, dating the texts they use is extremely controversial. We conclude with some positive remarks.     

Effects of physical and verbal aggression,depression, and anxiety on drinking behavior of married partners: a prospective and retrospective longitudinal examination

In an ethnically diverse sample of 195 married couples, we conducted a latent factor growth analysis to investigate the longitudinal link (4 time points over 4½ years) between marital aggression (physical and verbal aggression self‐ and partner‐reports) and individual internalizing symptoms (depression and anxiety) as they relate to trajectories of alcohol use among husbands and wives. Alcohol use was operationalized as a latent factor with self‐ and partner reports of problem drinking as measured by the Michigan Alcoholism Screening Test and the Alcohol Dependence Scale. Verbal aggression by husbands or wives, by itself, has no effect on their alcohol use over time. In conjunction with depression, however, verbally aggressive husbands do have elevated drinking levels. The effects of husbands' and wives' physical aggression on their own and their partners' drinking behavior were also significant. This study is one of the first to examine the change over time in alcohol use for marital partners as related to marital aggression and internalizing symptoms. Our results shed light on areas of marital functioning (aggression, internalizing, alcohol use) that have not been investigated in conjunction with each other in a longitudinal design. Aggr.

Sensory modalities in depth perception by golden hamsters

Golden hamsters are able to detect differences in the height of a platform from which they jump, as measured by their increasing latencies prior to jumping from increased elevations. This ability is very effective when optical information is available, but it is also present when hamsters jump in total darkness. A second experiment shows that, when hamsters are placed on a real physical cliff, they preferentially use tactile information over visual information to guide their choice of the side from which to descend. In a nonvisual setting, tactile stimulation is used in conjunction with other types of cues. Evidence is provided to suggest that these cues are of an acoustical nature.     

Retrieving names in old age: Short- and (very) long-term effects of repetition

Two experiments are reported that examine the effects of repetition on name retrieval in younger adults (in their 50s and 60s) and older adults (in their 70s and 80s). In Experiment 1, the subjects were asked to name a set of famous faces four times over the course of a 1-h session. Younger subjects produced significantly more correct responses than did older subjects. There was significant improvement with repeated attempts at naming, with younger and older subjects benefiting equally in terms of increasing numbers of correct responses across the session. In contrast, there was a highly significant age deficit in picture recognition over a similar retention interval. A qualitative analysis of naming responses (full name vs. part of the name) provided support for the view that aging and nonrecent use have equivalent effects on retrieval. In Experiment 2, younger subjects (but not older subjects) were significantly more likely to correctly name famous faces that they had seen 22 months previously than to correctly name new famous faces. In contrast, older subjects (but not younger subjects) were significantly more likely to produce erroneous names to famous faces that they had seen 22 months previously than to new famous faces. It is concluded that repetition priming may be relatively unaffected by aging over short retention intervals (Experiment 1) but not over a very long retention interval (Experiment 2).     

Magpies can use local cues to retrieve their food caches

Much importance has been placed on the use of spatial cues by food-hoarding birds in the retrieval of their caches. In this study, we investigate whether food-hoarding birds can be trained to use local cues (“beacons”) in their cache retrieval. We test magpies (Pica pica) in an active hoarding-retrieval paradigm, where local cues are always reliable, while spatial cues are not. Our results show that the birds use the local cues to retrieve their caches, even when occasionally contradicting spatial information is available. The design of our study does not allow us to test rigorously whether the birds prefer using local over spatial cues, nor to investigate the process through which they learn to use local cues. We furthermore provide evidence that magpies develop landmark preferences, which improve their retrieval accuracy. Our findings support the hypothesis that birds are flexible in their use of memory information, using a combination of the most reliable or salient information to retrieve their caches.     

The what,how much,and when of study strategies: comparing intended versus actual study behaviour

The study behaviours of students can be assessed from several perspectives, such as what study strategies are used, the total number of hours of study, and the distribution of studying over time. Here, we present the results of a survey study that considered each of these perspectives by asking students to report the what, how much, and when of their study behaviours over the course of a semester. As important, to better understand students’ use of study strategies, we also had students report at the beginning of the semester how they intended to study and their beliefs about the effectiveness of a variety of common strategies. Our results indicate that during the semester, students rely on relatively ineffective strategies and mass their studying the day or two before an exam. However, students intended to begin studying earlier and to use a mix of effective and ineffective study habits. Despite their use of some ineffective strategies, they did have a relatively accurate assessment of which strategies were less versus more effective. Taken together, our results suggest that students have some excellent intentions but may falter because massing study the evening before an exam limits their use of more effective study strategies.     

Voice stress analysis: Use of telephone recordings

Voice stress analyses were performed on tape recorded pre-employment interviews in both their original form and after they had been transmitted via telephone and re-recorded. Expert voice stress examiners, blind to the telephone condition, reported less stress in the telephone charts than in the original charts. There was little relationship between the stress rating for the same charts in their original and telephone forms. Reliability estimates were low for both the original and telephone stress ratings. Summing over the stress ratings from individual questions and advanced training on the part of the examiners both appeared to improve the reliability estimates. The continued use of telephone recorded tapes as substitutes for the original tapes is highly questionable. In addition, these results suggest that voice analysis ratings, as they are currently used, do not show sufficient reliability to warrant their continued use as a selection procedure for employment.An earlier version of this article was presented at the Ninety Third annual convention of the American Psychological Association.

Learning from experience: Examining the impact of client work upon two trainee therapists

This qualitative research study, focusing on the learning and change of two trainee therapists over a nine‐month period, was conducted by the trainees themselves. In collecting and analysing their data, the researchers made use of the heuristic methodology, to which some of the principles of the co‐operative inquiry methodology were added. The findings shed light on some of the ways in which trainee counsellors and psychotherapists might learn through their work with clients, the forms and contexts in which this learning may arise, and how the learning might affect the trainees. The findings additionally highlight some of the possible benefits of engaging in research for trainee counsellors and psychotherapists, in terms of their roles as practitioners. These include positive changes in the ways in which they work with clients, and changes in the ways they think about their practice.     

Speaker reliability guides children's inductive inferences about novel properties

Prior work shows that children can make inductive inferences about objects based on their labels rather than their appearance (Gelman, 2003). A separate line of research shows that children's trust in a speaker's label is selective. Children accept labels from a reliable speaker over an unreliable speaker (e.g., Koenig & Harris, 2005). In the current paper, we tested whether 3- and 5-year-old children attend to speaker reliability when they make inductive inferences about a non-obvious property of a novel artifact based on its label. Children were more likely to use a reliable speaker's label than an unreliable speaker's label when making inductive inferences. Thus, children not only prefer to learn from reliable speakers, they are also more likely to use information from reliable speakers as the basis for future inferences. The findings are discussed in light of the debate between a similarity-driven and a label-driven approach to inductive inferences.     

Changes in natural language use as an indicator of psychotherapeutic change in personality disorders

Word use has been shown to reflect various psychological processes and psychological change. This study examines the self-view in personality disorders (PDs) and its change over the course of therapy using the Linguistic Inquiry and Word Count analysis procedure. A sample of 299 participants with PDs and 108 community control participants wrote short essays about their lives. Patients repeated the assignment three times over two years and completed assessments of PD-pathology, general psychopathology, PD-beliefs, and quality of life. Results show that as hypothesized the use of words in the 1st Person Singular Pronouns, Negative Emotion, Causation, Past and Future Tense Verbs categories significantly declines over the course of treatment, while the use of Present Tense Verbs and Positive Emotion increases. These categories tend to distinguish patients from non-patients prior to treatment. We also found 12 additional word categories changing over time, including Word Count and Negations. Change in word use statistically predicts better treatment outcome on all outcome measures (p < .001). Reductions in the use of Negative Emotion Words and Negations are the strongest predictors of outcome. The non-hypothesized role of Negations was explored and seemed to reflect that PD-patients miss a lot in their lives. Reduction of what they miss seems central to recovery. This issue seems relatively neglected in theoretical and treatment models of PDs. An increased focus on what patients miss in their lives might improve our understanding and treatment of PDs. In sum, Negative Emotion and Negation word categories appear to reflect key treatment targets.     

The adaptive nature of children's overestimation in a strategic memory task

Kindergarten, first-, and third-grade children were given a multitrial sort-recall task with different items on each trial. Children were asked to predict how many items they would recall prior to each trial. We classified children into high- and low-overestimation groups based on their prediction accuracy on the first two trials and assessed changes in recall and strategy use over trials (trials 4/5 minus trials 1/2). Following predictions, at all grades, children in the high-overestimation group showed greater gains (or fewer losses) in recall than children in the low-overestimation group. Differences in strategy use over trials were generally nonsignificant. The results were interpreted as reflecting the adaptive nature of children's overestimation of their cognitive abilities.     

Retention and Recall: Incidental Learning of Visual and Auditory Material

This study examined the effect on observer agreement of switching from a system of overt reliability assessment to two successive systems of covert reliability measurement. A primary purpose was to see whether agreement obtained with the use of covert data checks would improve over time if observers were provided with accurate feedback regarding their level of agreement. Seventeen undergraduate psychology students served as Ss. They observed instructional interactions between preschool children and their teachers. During the two week “overt” check period (Phase I), observers were aware of when their observations were being “checked” by a previously designated reliability assessor. In the subsequent covert phases (weeks 3–7) this information was not available to them during the observational sessions. When covert monitoring was implemented, agreement rates initially dropped significantly below the “overt” measurement phase. Gradually agreement rates improved until, in weeks 6 and 7, they were not significantly different from the initial overt measures. Es should be aware that an overt check on observer agreement may not reflect the true reliability of an observational system. However, when observers are given accurate feedback on their level of agreement, they are able significantly to improve their vigilance and consistency in the use of the observational system.     

Family Experiences and Self-Criticism in College Students: Testing a Model of Family Stress,Past Unfairness,and Self-Esteem

Marriage and Family Therapists and other mental health professionals are often unaware of the sexual activity of preadolescent girls. The reason for this is the lack of research reporting on the sexual behavior of these young people. Also, in many cases the family may attend therapy for an unrelated issue and the sexual activity goes unnoticed. The present paper is an exploration into the lives of pre-teenagers' (ages 8–13) sex lives as they reported them in Internet chat rooms. Research on the content of chat rooms on the Internet is practically non-existent regarding this age group. Based on reports from over 1,300 pre-teen girls over a five-year time period, the results indicate that for some young girls, their young lives are filled with sexual behavior of one sort or another. They appear to be well versed in sexual terms and behaviors. In some cases the girls are forced into sexuality by a relative; in other cases, they appear to engage freely in sex with their boyfriends; in yet other cases they are forced by an older male. The girls overwhelmingly report that their parents are unaware of their sexual chatting on the Internet, even though it occurred regularly throughout the day. These girls are at risk. They are at risk for pregnancy and for sexual transmitted diseases, including HIV, not to mention the concomitant psychological effects. The data also indicate that the girls do not think about the consequences of their sexual behavior. Birth control and condom use appear not to be issues of concern for these young girls. Given the increased accessibility and use of the Internet by young people and the ability to create private spaces, blogs, and soon which are often sexual in nature, it is important for marriage and family therapists to understand the level of sexualization of some of these young girls in order to better address their needs and the needs of their families.     

Behavioral equipoise: a way to resolve ethical stalemates in clinical research

Randomized trials depend on clinicians feeling that they are morally justified in allowing their patients to be randomized across treatment arms. Typically such justification rides on what has been called "clinical equipoise"--when there is disagreement of opinion among the community of experts about whether one treatment is better than another, then physicians can ethically enter their patients into a clinical trial, even if individual physicians are not at equipoise. Recent debates over prominent studies, however, illustrate that controversy can be easily created rather than dispelled by trials, with many clinicians choosing not to use the proven therapy until they receive more convincing evidence of its superiority. In such situations, we propose that a new standard of equipoise be used to guide decisions about the ethical justifications for research trials--a standard of behavioral equipoise. Under behavioral equipoise, a trial is potentially justifiable if it addresses behavioral resistance to prior scientific evidence.     

Token transfer between mother and offspring chimpanzees (Pan troglodytes): mother–offspring interaction in a competitive situation

Chimpanzees can flexibly use tokens in cognitive tasks, but it is still unknown if they can share and/or compete over tokens as they do for food. This study aimed to evaluate the interactions spontaneously occurring between mother and offspring chimpanzees when tokens exchangeable for food were provided. Forty tokens were scattered on the floor in an experimental playroom. Three mother and offspring chimpanzee pairs were tested. Each token was exchangeable for a piece of food in a vending machine installed on the wall of the playroom. In the beginning of the study, both mother and offspring took tokens and exchanged them for pieces of food independently. Later, two offspring started to take more tokens than their mothers. At that time, the offspring whimpered or cried more often than during earlier sessions. This behavior compelled the mothers to abstain from taking tokens. The mothers sometimes shared their tokens with their offspring, or were tolerant of their offspring taking their tokens from their hand. For one pair, the offspring sometimes shared tokens with her mother when her mother begged for the tokens. These results suggest that chimpanzees’ cognitive abilities enable them not only to use tokens, but also to compete for tokens, as they do for food. The results also suggest that token sharing between mother and offspring may be bidirectional and that transfer of tokens mainly occurs as a result of begging, although on some occasion offspring were able to obtain a token directly from his/her mother through tolerated scrounging.
