Is knowing believing? The role of event plausibility and background knowledge in planting false beliefs about the personal past

False memories are more likely to be planted for plausible than for implausible events, but does just knowing about an implausible event make individuals more likely to think that the event happened to them? Two experiments assessed the independent contributions of plausibility and background knowledge to planting false beliefs. In Experiment 1, subjects rated 20 childhood events as to the likelihood of each event having happened to them. The list included the implausible target event “received an enema,” a critical target event of Pezdek, Finger, and Hodge (1997). Two weeks later, subjects were presented with (1) information regarding the high prevalence rate of enemas; (2) background information on how to administer an enema; (3) neither type of information; or (4) both. Immediately or 2 weeks later, they rated the 20 childhood events again. Only plausibility significantly increased occurrence ratings. In Experiment 2, the target event was changed from “barium enema administered in a hospital” to “home enema for constipation”; significant effects of both plausibility and background knowledge resulted. The results suggest that providing background knowledge can increase beliefs about personal events, but that its impact is limited by the extent of the individual’s familiarity with the context of the suggested target event.     

Do warnings of response verification moderate the relationship between personality and cognitive ability?

This article presents the results of 2 studies that examine the effect of presenting a warning of response verification by others on the relationship between measures of personality and cognitive ability. In both a field study and a laboratory study, stronger correlations were generally found between measures of personality and cognitive ability when a warning of verification was present. The results from the studies also showed that the warning of verification was associated with slower item response latencies for certain personality scales, suggesting that exposure to the warning increased the complexity of the response decision. Results are discussed in terms of the effects of altering test instructions on the construct validity of personality measures used in applied settings.     

Does the neighborhood context alter the link between youth's after-school time activities and developmental outcomes? A multilevel analysis

This article examines links between different measures of after-school time activity participation (5 specific activities and breadth) on youth's developmental outcomes (anxiety/depression, delinquency, and substance use) over 6 years and whether these links are moderated by neighborhood-level variables. The sample (N=1,315) of 9- and 12-year-old youth was drawn from the Project on Human Development in Chicago Neighborhoods (PHDCN), a multilevel, longitudinal study of youth from 80 Chicago neighborhoods. Findings revealed that different types of activities and patterns of participation over time were associated with outcomes for youth and that, to some extent, these outcomes varied with neighborhood characteristics. In brief, sports participation was associated with fewer anxious/depressed symptoms, higher average delinquency scores, and increased substance use-both average scores and growth over time. Participation in the arts and student government were negatively associated with average substance use and attenuated increases in usage over time. Participation in community-based clubs was positively associated with youth's anxiety/depression in violent neighborhoods only, whereas church groups were protective against substance use in nonviolent neighborhoods. The direction of the influence of breadth of participation was nonlinear for delinquency such that delinquency scores were highest among youth who engaged in an average number of activities.     

‘What do you mean by depression?’—A study of the relationship between antidepressive activity and personal concepts of depression

This study explores the relationship between a subject's concept of depression and his reported antidepressive activities. A pilot study is reported which was used to develop a method of classification of subjects' concepts of depression in terms of depth of depression and degree of external causality perceived. The majority of the subjects studied fitted into a group who see depression as a major disturbance of mood unrelated to external events; this was true for both the pilot and main studies. The main study applied the depressive classification method to an investigation of the relationship between depressive concept group and qualitative and quantitative aspects of reported repertoires for coping with depression. A major concept of depression was shown to be associated with a high frequency of reported antidepressive activity, but ANOVAR revealed no other significant main effect on quantitative analysis. Various complex interactions of sex. depth of concept and locus of concept were observed. A group of psychiatric inpatients were seen to differ in quantitative and qualitative aspects of reported antidepressive behaviour from the remainder of the population studied; the implications of these findings for further research are discussed.     

What do you learn about someone over time? The relationship between length of acquaintance and consensus and self-other agreement in judgments of personality

Theory and research examining length of acquaintance and consensus among personality judgments have predominantly examined each dimension of personality separately. In L. J. Cronbach's (1955) terminology, this trait-centered approach combines consensus on elevation, differential elevation, and differential accuracy in personality judgments. The current article extends D. A. Kenny's (1991, 1994) weighted average model (WAM)--a theoretical model of the factors that influence agreement among personality judgments--to separate out two of Cronbach's components of consensus: stereotype accuracy and differential accuracy. Consistent with the predictions based on the WAM, as length of acquaintance increased, self-other agreement and consensus differential accuracy increased, stereotype accuracy decreased, and trait-level or raw profile correlations generally remained unchanged. Discussion focuses on the conditions under which a relationship between length of acquaintance and consensus and self-other agreement among personality evaluations emerges and how impressions change over time.     

Why are you telling me that? A conceptual model of the social function of autobiographical memory

In an effort to stimulate and guide empirical work within a functional framework, this paper provides a conceptual model of the social functions of autobiographical memory (AM) across the lifespan. The model delineates the processes and variables involved when AMs are shared to serve social functions. Components of the model include: lifespan contextual influences, the qualitative characteristics of memory (emotionality and level of detail recalled), the speaker's characteristics (age, gender, and personality), the familiarity and similarity of the listener to the speaker, the level of responsiveness during the memory-sharing process, and the nature of the social relationship in which the memory sharing occurs (valence and length of the relationship). These components are shown to influence the type of social function served and/or, the extent to which social functions are served. Directions for future empirical work to substantiate the model and hypotheses derived from the model are provided.     

Does human capital matter? A meta-analysis of the relationship between human capital and firm performance

Theory at both the micro and macro level predicts that investments in superior human capital generate better firm-level performance. However, human capital takes time and money to develop or acquire, which potentially offsets its positive benefits. Indeed, extant tests appear equivocal regarding its impact. To clarify what is known, we meta-analyzed effects drawn from 66 studies of the human capital-firm performance relationship and investigated 3 moderators suggested by resource-based theory. We found that human capital relates strongly to performance, especially when the human capital in question is not readily tradable in labor markets and when researchers use operational performance measures that are not subject to profit appropriation. Our results suggest that managers should invest in programs that increase and retain firm-specific human capital.

Did Kant Conflate the Necessary and the A Priori?

It is commonly accepted by Kant scholars that Kant held that all necessary truths are a priori, and all a priori knowledge is knowledge of necessary truths. Against the prevailing interpretation, I argue that Kant was agnostic as to whether necessity and a priority are co‐extensive. I focus on three kinds of modality Kant implicitly distinguishes: formal possibility and necessity, empirical possibility and necessity, and noumenal possibility and necessity. Formal possibility is compatibility with the forms of experience; empirical possibility is compatibility with the causal powers of empirical objects; noumenal possibility is compatibility with the causal powers of things in themselves. Because we cannot know the causal powers of things in themselves, we cannot know what is noumenally necessary and what is noumenally contingent. Consequently, we cannot know whether noumenal necessity is co‐extensive with a priority. Therefore, for all we know, some a priori propositions are noumenally contingent, and some a posteriori propositions are noumenally necessary. Thus, contrary to the received interpretation, Kant distinguishes epistemological from metaphysical modality.     

A multidimensional analysis of internal health locus of control beliefs: separating the wheat from the chaff?

The current study examined the hypotheses that internal health locus of control comprises multiple dimensions and that these dimensions are differentially associated with physical health status. As expected, using covariance structure modeling of data derived from 181 medical outpatients, internal health locus of control was found to be multidimensional. Predicted dimensions included recognition that illness prevention is contingent on successful execution of potential health actions, recognition that illness management is contingent on successful execution of potential health actions, and self-mastery over health outcomes (i.e., the perceived capacity to achieve desired health outcomes). A 4th dimension (i.e., self-blame for negative health outcomes) also emerged. Moreover, as predicted, only perceptions of self-mastery were independently associated with indexes of physical health and well-being.     

What is the size of the relationship between global mental toughness and youth experiences?

Youth experiences are a core requirement for components of positive youth development and may be associated with an athlete’s mental toughness. The purposes of this study were to examine the relationship between mental toughness and youth experiences. Two hundred and ninety nine athletes (M_age 19.48 years, SD 1.30) completed the Sport Mental Toughness Questionnaire and Youth Experiences Survey. We then conducted a standard multiple regression on the data. R for regression was significantly different from zero, F(6, 292) = 8.106, p = .0001, with R² at .14. Altogether, 14% (13% adjusted) of the variance in mental toughness was accounted for by youth experiences. These results reveal that initiative experiences have the strongest relationship with mental toughness; however, youth experiences may not be as important as previous studies suggest.     

Does sex moderate the relationship between anxiety and pain?

Objectives : Sex differences exist in the relationship between anxiety and pain, although findings are mixed. One reason could be because a number of anxiety measures have been used. Therefore, this study aimed to identify the core components within commonly used pain anxiety measures, and see whether these components are differentially related to sensation and pain thresholds in men and women.

Design, main outcome measures : One hundred and eighty-nine healthy adults (119 female) completed the Fear of Pain Questionnaire, Pain Catastrophising Scale, Pain Anxiety Symptoms Scale, Anxiety Sensitivity Index-3 and the Depression Anxiety Stress Scale. Thermal sensation and pain thresholds, mechanical sensation and pressure pain thresholds were also collected.

Results : A Principal Components Analysis of anxiety measures revealed three constructs: general distress, cognitive intrusion and fear of pain from injury/insult. Sex did not moderate the relationship between these anxiety constructs and sensation/pain thresholds. However, a significant main effect of sex was found to predict thermal pain thresholds.

Conclusion : Preliminary indications suggest that pain anxiety dimensions can be reduced to three core constructs, and used to examine pain sensation. However, sex did not moderate this relationship. Further research is required to establish the extent and strength of sex differences in the relationship between anxiety and pain.     

Do response time advantage and interference reflect the order of processing of global- and local-level information?

Navon's (1977) global precedence hypothesis was based primarily on the joint occurrence of two effects: a response time (RT) advantage for identifying global targets, and interference by global distractors on responding to local targets. Although the hypothesis has been questioned on the basis of experiments in which it has been shown that a local RT advantage and local interference can occur, it is still frequently assumed that these two effects are a valid measure of the order in which local and global levels of structure are processed. In the present experiment, this assumption was examined. Subjects identified target letters that occurred randomly at the global or local level in a divided-attention task. The visual angle subtended by the stimulus pattern was varied, a manipulation known to affect the relative speed of response to local- or global-level information. Local targets were identified faster than global targets at the larger visual angles, but there was no difference in RT at the smallest visual angle. Despite this change in RT advantage, the interference effect did not change as a function of the visual angle of the stimulus pattern. Moreover, global distractors interfered with responding to local targets but local targets had no effect on responding to global targets, which is exactly the opposite of the finding one would expect if RT advantage and interference reflected order of processing. These findings are not consistent with the assumption that RT advantage and interference reflect order of processing in a simple way.     

Do you believe happiness can change? An investigation of the relationship between happiness mindsets,well-being,and satisfaction

Three studies (N = 794) examined if beliefs about the malleable nature of happiness (growth mindsets) are associated with well-being and if this well-being had downstream implications for satisfaction with one’s relationships (Studies 1–3), health (Study 3), and job (Study 3). In Study 1 (N = 277), happiness growth mindsets were associated with greater well-being and greater relationship satisfaction. In Study 2 (N = 337), using an experimental paradigm and serial mediation, encouraging growth mindsets led to stronger beliefs in the changeable nature of happiness, which in turn was associated with subjective well-being, and, finally, relationship satisfaction. In Study 3 (N = 180), we replicated the downstream effects of growth mindsets of happiness on well-being and subsequently on relationship satisfaction and extended these serial mediation effects to health and job satisfaction. We discuss the implications of happiness mindsets.     

How does persistent pain develop? An analysis of the relationship between psychological variables, pain and function across stages of chronicity

The fear-avoidance model is an attempt to underscore the importance of cognitive and behavioral factors, in a chain of events linking pain to disability. However, it is not clear at what time point the psychological variables within the model begin to be prominent. The aim of this study was to investigate the role of these psychological variables in the development of a chronic musculoskeletal pain problem. Three stages of chronicity, defined by duration of pain, provided a proxy for the developmental process: <1 year (N=48), 1-3 years (N=47) and >3 years (N=89). Subjects completed questionnaires on fear of movement, catastrophizing, depression, pain and function. The results indicate that the relationship between fear of movement and function is moderated by the stage of chronicity. Regression analyses showed that fear of movement did not explain any variance in the group with pain duration <1 year. Fear of movement did explain variance in the groups with pain duration of 1-3 years and >3 years. This suggests that the time point in the development of a musculoskeletal pain problem might be an essential aspect of the importance of the relationship between psychological components and function.     

What is the role of narcissism in the relationship between impulsivity and driving anger expression?

The contributing factors of aggressive driving have been studying in the last decades. Both impulsivity and narcissism are associated with aggressive driver behaviors. Although the role of these two factors were examined in the same studies, the combined role of these two factors hasn’t been studied yet. To understand the combined effect of them, in the present study, the moderated mediation model for examining the relationships of narcissism, impulsivity, and aggressive driver behavior was developed and tested. Three hundred and four participants completed an online survey battery comprised of Demographic Information Form, Five-Factor Narcissism Inventory-Short Form, Barrat Impulsiveness Scale- Short Form, and Driving Anger Expression Inventory. The moderated mediation analyses were conducted using PROCESS macro developed by Hayes and Preacher (2013). The results revealed that only the relationship between vulnerable narcissism and the use of vehicle to express anger is mediated by attentional impulsiveness. Also, this relationship is moderated by grandiose narcissism. In detail, grandiose narcissism moderates the direct effect of vulnerable narcissism on attentional impulsivity and also the direct effect of attentional impulsivity on the use of vehicle to express anger. Theoretical and practical implications of these findings and recommendations for future studies are discussed.     

Can the relationship between tangential velocity and radius of curvature explain motor constancy?

To address contributions of speed, efficiency, radius of curvature and joint complexity to the strength of the lawful relationship between tangential velocity and radius of curvature (power law), an experiment considered the strength of the power law when participants were instructed to perform circling movements using the elbow, finger, shoulder, or wrist. Five participants performed circling motions in a vertical plane upon a Smartboard that sampled finger tip position at 200Hz. Page's L tested whether the strength of the power law could be predicted by: (1) speed; (2) submovements; (3) joint complexity; (4) radius of curvature. A second experiment considered the strength of the power law when six participants were instructed to perform circling movements of different sizes (large, medium, and small) using their shoulders. Movement speed or efficiency could not explain the strength of the power law, instead the power law was stronger for movements with a smaller radius of curvature or fewer joints. The strength of the power law varied with effector, questioning the role of the power law in motor constancy.     

Great man or great myth? A quantitative review of the relationship between individual differences and leader effectiveness

This study presents a meta‐analysis of 25 individual differences proposed to be related to effective leadership, with an emphasis on comparing trait‐like (e.g. personality and intelligence) to state‐like individual differences (e.g. knowledge and skills). The results indicate that although both trait‐like (achievement motivation, energy, dominance, honesty/integrity, self‐confidence, creativity, and charisma) and state‐like (interpersonal skills, oral communication, written communication, administrative/management skills, problem‐solving skills, and decision making) individual differences were consistent predictors of effective leadership, the impact of trait‐like and state‐like individual differences was modest overall and did not differ substantially (ρ= .27 and .26, respectively). Finally, organizational level of the leader, method of predictor and criterion measurement, and organization type moderated the relationship between individual differences and effective leadership.     

What is the relationship between Aphantasia,Synaesthesia and Autism?

For people with aphantasia, visual imagery is absent or markedly impaired. Here, we investigated the relationship between aphantasia and two other neurodevelopmental conditions also linked to imagery differences: synaesthesia, and autism. In Experiment 1a and 1b, we asked whether aphantasia and synaesthesia can co-occur, an important question given that synaesthesia is linked to strong imagery. Taking grapheme-colour synaesthesia as a test case, we found that synaesthesia can be objectively diagnosed in aphantasics, suggesting visual imagery is not necessary for synaesthesia to occur. However, aphantasia influenced the type of synaesthesia experienced (favouring ‘associator’ over ‘projector’ synaesthesia - a distinction tied to the phenomenology of the synaesthetic experience). In Experiment 2, we asked whether aphantasics have traits associated with autism, an important question given that autism – like aphantasia – is linked to weak imagery. We found that aphantasics reported more autistic traits than controls, with weaknesses in imagination and social skills.
