Inducing affective states with success-failure manipulations: a meta-analysis

Meta-analytic techniques were used to assess whether successes and failures can be used experimentally to induce affective states. Data from 32 studies, with a total of 2,468 participants, were reviewed. Methods for producing success-failure experiences, as well as the resulting affective reactions, were analyzed. Effect sizes as a result of various methods of induction were calculated. The success-failure manipulation turned out to be capable of reliably inducing both positive and negative affective reactions. A framework for using success-failure manipulations in affect induction is presented. ((c) 2004 APA, all rights reserved)     

Personality dynamics: insights from the personality social cognitive literature

Psychodynamic and social cognitive approaches to personality assessment converge now more so than at any time in the history of experimental psychology. This contribution seeks to make this point. First, the trait of neuroticism predisposes one to multiple adverse outcomes, a point not sufficiently captured by the current version of the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994). Second, though, self-reported levels of neuroticism are insufficient in understanding problematic outcomes for multiple reasons. Third, there are ways of experimentally modeling the many processes of interest to psychodynamic theorists such as unconscious affective biases, implicit representations of self and other, and underlying deficits in self- and emotion regulation. Implicit approaches to assessment also provide clues to interventions targeting the processes of interest, a point that will be made as well.     

Personality correlates of heroic rescue during the holocaust

This study investigated the extent to which personality variables can be used to discriminate non-Jewish heroes of the Holocaust from bystanders and from a comparison group of prewar European immigrants who left their countries of origin prior to World War II. Eighty verified rescuers, 73 bystanders, and 43 immigrants were administered measures of locus of control, autonomy, risk taking, social responsibility, tolerance/authoritarianism, empathy, and altruistic moral reasoning. A three-group discriminant function analysis was able to correctly classify 80.2% of the sample by a combination of personality and demographic variables. When the bystanders and immigrants, who differed very little from each other, were grouped together and compared to the rescuers, the personality variables alone correctly classified 93.1% of the sample. Implications regarding the relationship between personality and altruistic behavior, as well as suggestions for future research are discussed.     

从传统现实人格到现代理想人格

经济、社会的发展 ,离不开人的发展 ,而人的发展的最终目标乃是造就高尚健全的人格。上个世纪初的文化“启蒙” ,即所谓“改革国民性”的任务 ,就是为了追求这一目标。一百年来 ,传统社会的外部形态起了巨变 ,然而“国民性格”的改造并未取得长足进展。面向新世纪 ,启蒙的任务更加紧迫了。但是今天 ,我们的国家 ,正处于历史上的最好时期 ,有良好的内部外部条件 ,因此我们相信 :在物质经济迅速发展的基础上 ,通过国家领导、人文学者、广大民众举国上下的一致努力 ,在新世纪一定能完成“国民性”改造任务 ,实现全体国民从传统现实人格向现代理想人格的转化 ,从而实现从传统到现代的社会转型 ,最终成为名副其实的现代化国家。     

Response-time dynamics: Evidence for linear and low-dimensional nonlinear structure in human choice sequences

Response time (RT) is a commonly used measure of cognitive performance, which is usually characterized as stochastic. However, useful information may be hidden in the apparently random fluctuations of RT. Dynamical systems analysis techniques allow an exploration of the alternative hypothesis that RT fluctuations are deterministic, albeit in a complex manner. We applied careful task construction and noise-reduction and surrogate series tests to show that RT series from a forced-pace serial response-time task have low-dimensional chaotic characteristics. In Experiment 1, 80% of subjects' filtered RT series had low dimensionality, sensitive dependence on initial conditions, spectra close to 1/ f , and stable attractor geometry across sessions. In Experiment 2, we showed that the size of the inter-stimulus interval (ISI) determined the number of subjects with low-dimensional chaotic series. A small ISI caused 100% of subjects to respond in the chaotic regime, whereas only 25% had a low-dimensional chaotic RT component when the ISI was large. We argue that demanding task requirements cause a reduction in the dimensionality of the dynamics, producing RT fluctuations that may reflect a response strategy for controlling RT.     

Course of Antisocial Behavior during Emerging Adulthood: Developmental Differences in Personality

Despite similar normative changes in antisocial behavior (AB) and traits of disinhibition and negative emotionality during "emerging adulthood," few studies have tested if there are developmental differences in personality over this period for distinct courses of AB. In a college cohort assessed at ages 18 and 25, we examined if mean-level changes on traits from the Tridimensional Personality Questionnaire varied by course of AB. Compared to persisters, those who desisted in AB from 18 to 25 exhibited a larger decrease on novelty seeking and larger increase on reward dependence. A significant mean-level decline was observed for harm avoidance, but was unrelated to AB course. Findings support theories of the co-development of personality and AB during emerging adulthood.     

Electrophysiological spatiotemporal dynamics during implicit visual threat processing

Numerous studies have found evidence for corticolimbic theta band electroencephalographic (EEG) oscillations in the neural processing of visual stimuli perceived as threatening. However, varying temporal and topographical patterns have emerged, possibly due to varying arousal levels of the stimuli. In addition, recent studies suggest neural oscillations in delta, theta, alpha, and beta-band frequencies play a functional role in information processing in the brain. This study implemented a data-driven PCA based analysis investigating the spatiotemporal dynamics of electroencephalographic delta, theta, alpha, and beta-band frequencies during an implicit visual threat processing task. While controlling for the arousal dimension (the intensity of emotional activation), we found several spatial and temporal differences for threatening compared to nonthreatening visual images. We detected an early posterior increase in theta power followed by a later frontal increase in theta power, greatest for the threatening condition. There was also a consistent left lateralized beta desynchronization for the threatening condition. Our results provide support for a dynamic corticolimbic network, with theta and beta band activity indexing processes pivotal in visual threat processing.     

Readability of Three Adult Personality Tests: Basic Personality Inventory,Jackson Personality Inventory,and Personality Research Form-E

Three personality tests, the Basic Personality Inventory (BPI), the Jackson Personality Inventory (JPI), and the Personality Research Form-E (PRF-E) were evaluated for readability using a number of indices. Sentence length, word length, sentence type, and four readability formulas indicated that the readability of the BPI, JPI, and PRF-E would not impede the administration or interpretation of these tests in broad segments of the population.     

Personality and the predisposition to engage in risky or problem behaviors during adolescence

Longitudinal data from a representative sample of 1,978 Black and White adolescents were used to examine the role of personality in multiple risk or problem behaviors. Results indicate that covariation among diverse behaviors (educational underachievement, delinquent behavior, substance use, sexual behavior) can be adequately modeled by a single higher order factor, and that impulsivity and avoidance coping serve as generalized risk factors for involvement in these behaviors. Whereas none of the personality variables examined explained change in problem behaviors once established, avoidance coping prospectively predicted involvement among a subgroup of adolescents with little or no prior involvement. Results suggest that dysfunctional styles of regulating emotions and emotionally driven behaviors are core features of risky or problem behaviors during adolescence.     

Personality and relationship quality during the transition from high school to early adulthood

The post-high school transition period is believed to be associated with considerable changes in social networks, yet longitudinal studies documenting these changes are scarce. To address this gap, the current research explored 3 relevant issues. First, changes in participants' relationship characteristics during the transition from high school were examined. Second, the roles of personality traits as antecedents of these changes were studied. Third, the association between change in relationship characteristics and personality during the transition was explored. A sample of over 2,000 German emerging adults, surveyed before leaving school and then 2 years after the transition from high school, was assessed on personality traits and a multidimensional assessment of the quality of their relationships. Findings indicated that participants experienced mostly positive changes in relationship quality during the transition from high school and that antecedent personality at school was an important predictor of the nature of this change. Finally, change in relationship quality was found to be associated with personality change during the post-school transition. Findings indicated that personality traits may influence transition success and that change in relationships during this transition may influence personality development. The implications of the research for post-school transition success are discussed.     

Cracking the Plaster Cast: Big Five Personality Change during Intensive Outpatient Counseling

This study attempted to evaluate the ability of an outpatient drug rehabilitation program to effect significant shifts on the five major dimensions of personality. A mostly African American sample of 82 men and 50 women entering a 6-week program were assessed at admission, and the 99 who completed were again measured at termination. Follow-up assessments were completed on 30 clients an average of 15 months later. Results indicated significant shifts on all five personality domains from pre- to posttreatment (mean Cohen's d = .38). Significant shifts on Neuroticism, Agreeableness, and Conscientiousness were maintained over follow-up (mean Cohen's d = .28). These results suggest that personality change may be possible in the context of treatment.
