Are intrusive thoughts subject to habituation?

The main question was addressed by studying three groups of non-psychiatric subjects who experienced intrusive and distressing thoughts. The effects of one of three forms of habituation training (massed, spaced and spaced combined with relaxation) on selected thoughts were assessed on a range of measures including latency, duration, discomfort, fading and so on.It appears that intrusive thoughts are subject to habituation. Broad decrements of significant magnitude were observed after each of three forms of habitation training. However, the occurrence of unpredicted decrements attributable to practice effects and to relaxation, presents some problems of interpretation.     

Do men and women use different tactics to cope with the embarrassment of buying condoms?

It has been proposed that people cope with the embarrassment of acquiring condoms using a variety of tactics, such as buying from a sales clerk of the same gender or buying additional products. However, the actual use and efficacy of these coping mechanisms have not been rigorously evaluated. This research investigates three specific questions related to coping with embarrassment: (R1) Do people prefer cashiers of the same gender when buying condoms because it helps them cope with embarrassment or because of the similarity‐attraction effect? (R2) When multiple coping mechanisms are available, do people use more than one at a time? And (R3) Do men and women prefer different coping tactics? Using an experimental design, Study 1 investigates R1 and finds support for both explanations. Studies 2 and 3 use field and lab experiments, respectively, to investigate R2 and R3. The findings indicate that people only use one coping tactic at a time and that men and women have a different preference for coping tactics. Women prefer coping tactics that mask condom acquisition, while men prefer social–emotional support tactics. Furthermore, discrepancies between the field experiment and lab experiments indicate that people underestimate the influence of embarrassment on their actual behavior.     

Do men lie on fear surveys?

The likelihood that males equivocate in their ratings of common fears was evaluated. A fear survey was given to 30 female and 26 male college students in a classroom setting. A second fear survey which contained duplicate items from the first was administered to the same students in a laboratory setting prior to watching videotaped scenes of fish, rats, mice and a shorter roller coaster ride. Before the second survey was given, the students received instructions which implied that their truthfulness could be independently evaluated through changes in their heart rate while they watched the videotape. Changes in the averaged fear ratings for the three high-fear items shown in the videotaped scenes were compared between males and females across the two survey conditions. Males' ratings of rats, mice, and roller coasters increased markedly from the first survey to the second, while fear ratings by females did not change. These results are consistent with the idea that the expression of fear by men is affected by conformation to the traditional male gender role.     

Does anxiety lead to selective processing of threat-related information?

Four experiments investigating the detailed nature of the attentional bias in anxiety are reported. Previous research using the Stroop task has shown that, when compared with non-patient controls, anxious patients are relatively slower at colour naming threat-related words than non-threat words. Experiments One and Two investigated whether this apparent attentional bias is a function of anxiety per se and/or is related to patient/non-patient status. Experiment One compared colour-naming times for threat and non-threat words in low, medium and high trait anxiety normal subjects. High anxiety was not associated with slower colour-naming times for threat words. Experiment Two compared generalized anxiety disorder patients with equally anxious non-patients and found that the patients were significantly slower at colour-naming threat words. Read aloud and dwell tasks were also included in these experiments in order to identify the mechanism of Stroop interference. Experiments Three and Four investigated whether anxious patients' attentional bias is specific to threat-related material or also extends to certain positive, emotional material. In Experiment Three words used in previous Stroop studies were rated for emotionality. Threat words were more emotional, as well as more threatening, than control words, indicating that previous studies have confounded threat and emotionality. Experiment Four compared colour-naming times for threat words, equally emotional positive words, and neutral words. Consistent with the emotionality hypothesis, generalized anxiety disorder patients were slower than non-anxious controls at colour naming both threat words and positive words. The theoretical, methodological and clinical implications of these results are discussed.     

Do automatic reactions elicited by thoughts of romantic partner, mother, and self relate to adult romantic attachment?

Three studies tested the expectation that automatic reactions elicited by the mental representation of one's current romantic partner, mother, and self relate to adult romantic attachment. Adult romantic attachment was assessed using multiple measures, and individual differences in automatic reactions were assessed by the Implicit Association Test (IAT). Studies 1 and 2 showed that automatic reactions elicited by thoughts of current romantic partner, but not by thoughts of self, were related to adult romantic attachment assessed at a specific (i.e., within one's current romantic relationship) and general level (i.e., across all romantic relationships). The pattern of results was stronger among individuals identified as attachment-schematic. Studies 2 and 3 showed that automatic reactions elicited by thoughts of one's mother were related to adult romantic attachment assessed at a general level. In all three studies, results did not differ depending on how adult romantic attachment was conceptualized (four styles vs. two dimensions).     

Sex ratio and women's career choice: does a scarcity of men lead women to choose briefcase over baby?

Although the ratio of males to females in a population is known to influence behavior in nonhuman animals, little is known about how sex ratio influences human behavior. We propose that sex ratio affects women's family planning and career choices. Using both historical data and experiments, we examined how sex ratio influences women's career aspirations. Findings showed that a scarcity of men led women to seek high-paying careers and to delay starting a family. This effect was driven by how sex ratio altered the mating market, not just the job market. Sex ratios involving a scarcity of men led women to seek lucrative careers because of the difficulty women have in finding an investing, long-term mate under such circumstances. Accordingly, this low-male sex ratio produced the strongest desire for lucrative careers in women who are least able to secure a mate. These findings demonstrate that sex ratio has far-reaching effects in humans, including whether women choose briefcase over baby.     

Predicting marital satisfaction from behavior: Do all roads really lead to Rome?

The concurrent and longitudinal associations between spousal communication and marital satisfaction were investigated using two systems of observation (rating and coding) and two statistical methods. A coding system and a rating system were used to assess the amount of positive, negative, and avoidant behavior exhibited by 30 couples engaged in a 15-minute discussion about a marital problem. Change scores as well as regression methods were used to calculate correlations between communication behaviors and one-year change in Marital Adjustment Test (MAT) scores. Positive behavior by both spouses predicted an increase in wives' satisfaction, and negative behavior by both spouses predicted a decrease in wives' satisfaction. None of the variables consistently predicted changes in husbands' satisfaction. The two systems of observation and the two methods of analysis produced similar though not identical results. The article discusses the constructs of negative and avoidant behavior, reviews limitations of standard marital research methods, and offers theoretical and methodological recommendations for future research.     

Does lack of control lead to conspiracy beliefs? A meta-analysis

Perceived lack of control is widely believed to motivate, at least partly, belief in conspiracy theories. We question the theoretical foundations of this belief and meta-analyze existing published and unpublished studies to assess the overall effect of lack of control on conspiracy beliefs. The overall effect was small and not statistically significant (d = −0.05), and was not moderated by comparison group (baseline vs. control affirmation), type of manipulation used to threaten control, inclusion of a manipulation check, or sample type. However, the predicted effect of control was more likely to be observed when beliefs were measured in terms of specific conspiracy theories, rather than as general or abstract claims. Overall, the present studies to date offer limited support for the hypothesis that conspiracy beliefs arise as a compensatory control.     

Do 5% changes around maximal lactate steady state lead to swimming biophysical modifications?

Our purpose was to examine the swimming biophysical responses at velocities (v) of 97.5, 100 and 102.5% of the maximal lactate steady state (MLSS). Ten elite female swimmers performed three-to-five 30-min constant tests at imposed paces to determine 97.5, 100 and 102.5%MLSS v. Gas exchange, blood lactate concentration ([La-]), stroke rate (SR) and v were determined during each test. The v values at 97.5, 100 and 102.5%MLSS were 1.21 ± 0.07, 1.24 ± 0.07 and 1.27 ± 0.07 m.s⁻¹, respectively. Oxygen uptake (V̇O₂) and Pulmonary ventilation (V̇E) increased as function of v. SR and stroke length (v/SR = SL) increased as a function of v. All measured variables were constant as a function of time at 97.5%MLSS and 100%MLSS. At 102.5%MLSS SR increased (3.5%) and stroke length (SL) decreased (3.5%) as a function of time. While V̇O₂ was constant at 102.5%MLSS, [La-] and V̇E increased as a function of time, suggesting hyperventilation, at v’s of 97.5%MLSS and 100%MLSS swimmers completed the 30 min swim in spite of decreased SL and increased SR. However, the decrease in SL and increased SF were accompanied by increased [La-] and V̇E and resulted in the inability of most swimmers to complete the 30 min swim presumably due to fatigue at 102.5%MLSS.     

Does category labeling lead to forgetting?

What effect does labeling an object as a member of a familiar category have on memory for that object? Recent studies suggest that recognition memory can be negatively impacted by categorizing objects during encoding. This paper examines the “representational shift hypothesis” which argues that categorizing an object impairs recognition memory by altering the trace of the encoded memory to be more similar to the category prototype. Previous evidence for this idea comes from experiments in which a basic-level category labeling task was compared to a non-category labeling incidental encoding task, usually a preference judgment (e.g., “Do you like this item?”). In two experiments, we examine alternative tasks that attempt to control for processing demands and the degree to which category information is explicitly recruited at the time of study. Contrary to the predictions of the representational shift hypothesis, we find no evidence that memory is selectively impaired by category labeling. Overall, the pattern of results across both studies appears consistent with well-established variables known to influence memory such as encoding specificity and distinctiveness effects.     

Does reflection lead to wise choices?

Does conscious reflection lead to good decision-making? Whereas engaging in reflection is traditionally thought to be the best way to make wise choices, recent psychological evidence undermines the role of reflection in lay and expert judgement. The literature suggests that thinking about reasons does not improve the choices people make, and that experts do not engage in reflection, but base their judgements on intuition, often shaped by extensive previous experience. Can we square the traditional accounts of wisdom with the results of these empirical studies? Should we even attempt to? I shall defend the view that philosophy and cognitive sciences genuinely interact in tackling questions such as whether reflection leads to making wise choices.     

Does subgroup membership information lead to better estimation of true subscores?

Haberman (2008) suggested a method to determine if subtest scores have added value over the total score. The method is based on classical test theory and considers the estimation of the true subscores. Performance of subgroups, for example, those based on gender or ethnicity, on subtests is often of interest. Researchers such as Stricker (1993) and Livingston and Rupp (2004) found that the difference in performance between the subgroups often varies over the different subtests. We suggest a method to examine whether the knowledge of the subgroup membership of the examinees leads to a better estimation of the true subscores. We apply our suggested method to data from two operational testing programmes. The knowledge of the subgroup membership of the examinees does not lead to a better estimation of the true subscore for the data sets.     

Behavioral and psychological implications of body dissatisfaction: Do men and women differ?

The relationships of body satisfaction, self-esteem, dieting, and exercise were studied in 92 men and women. Men and women did not differ in degree of body dissatisfaction as assessed by three different measures. However, on the direction of body dissatisfaction, men were as likely to want to be heavier as thinner, whereas virtually no women wished to be heavier. Although overall body esteem was correlated with self-esteem for both men and women, measures of weight dissatisfaction were not associated with self-esteem for women. The normative nature of weight dissatisfaction for women today may serve to buffer its effects on self-esteem. Women reported exercising for weight control more than men, and exercising for weight control was associated with disregulated eating.     

Does drug mis-instrumentalization lead to drug abuse?

Understanding the perceived benefits of using drugs to achieve specific mental states will provide novel insights into the reasons individuals seek to use drugs. However, the precision of attempts to instrumentalize drugs is unclear both across drugs and individuals. Moreover, mis-instrumentalization, defined as discrepancies between such endpoints, may have relevance to understanding the relation among use, abuse, and addiction.     

Can manipulations of cognitive load be used to test evolutionary hypotheses?

D. DeSteno, M. Y. Bartlett, J. Braverman, and P. Salovey proposed that if sex-differentiated responses to infidelity are evolved, then they should be automatic, and therefore cognitive load should not attenuate them. DeSteno et al. found smaller sex differences in response to sexual versus emotional infidelity among participants under cognitive load, an effect interpreted as evidence against the evolutionary hypothesis. This logic is faulty. Cognitive load probably affects mechanisms involved in simulating infidelity experiences, thus seriously challenging the usefulness of cognitive load manipulations in testing hypotheses involving simulation. The method also entails the assumption that evolved jealousy mechanisms are necessarily automatic, an assumption not supported by theory or evidence. Regardless of how the jealousy debate is eventually settled, cognitive load manipulations cannot rule out the operation of evolved mechanisms.     

Happiness: When does it lead to self-indulgence and when does it lead to self-denial?

Previous research on self-gratification in children has found that happiness, compared to a neutral affective state, sometimes causes self-indulgence and sometimes causes self-denial. Review of this research led to the hypothesis that happiness leads to self-indulgence when children have no reason to believe that excessive self-gratification is morally wrong but that happiness promotes selfdenial when children fear that excessive self-gratification would violate a moral rule. In the present study, children were first placed in either a happy or neutral mood. They were then given an opportunity to help themselves freely to a reward supply, but half the children in each affect condition were warned that excessive self-gratification would violate a moral rule whereas the other half were not. In the absence of information that excessive self-gratification would violate a moral standard, happiness produced self-indulgence, but when children were told that excessive self-gratification would be wrong, happy children denied themselves significantly more than neutral-mood children. It was suggested that happiness motivates children to try to sustain their elevated mood; the behavioral route to maintaining positive mood, however, depends on how children perceive the moral implications of their actions.     

The benefits of frequent positive affect: does happiness lead to success?

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors suggest a conceptual model to account for these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive affect engenders success. Three classes of evidence--crosssectional, longitudinal, and experimental--are documented to test their model. Relevant studies are described and their effect sizes combined meta-analytically. The results reveal that happiness is associated with and precedes numerous successful outcomes, as well as behaviors paralleling success. Furthermore, the evidence suggests that positive affect--the hallmark of well-being--may be the cause of many of the desirable characteristics, resources, and successes correlated with happiness. Limitations, empirical issues, and important future research questions are discussed.
