Different temporary work status, different behaviors in organization

This study examined the contributions of the psychological contract framework to an understanding of the effects of different work statuses on employees’ behavior. We compared temporary firm workers (n=71) with core workers (n=268) and direct-hire temporary workers (n=149) with core workers (n=42) in two different samples. As expected, temporary firm workers consider that they receive fewer socio-emotional inducements from the organization they work for (opportunities for promotion, career development, long-term employment), but direct-hire temporary workers who succeeded in having their contracts extended had a psychological contract in which socio-emotional components predominated. A psychological contract with a predominance of socio-emotional components was important for organizations because it mediated the influence of work status on civic virtue behaviors on the part of temporary firm workers, and directly and positively influenced these behaviors in direct-hired temporary workers (behaviors as assessed by their supervisors). Contrary to the hypothesis, psychological contract had a direct and positive influence on the in-role behavior of direct-hire temporary workers. The implications of the findings for psychological contract research are discussed.     

Knowledge, Naturalism, and Cognitive Ethology: Kornblith’s Knowledge and its Place in Nature

This paper explores Kornblith’s proposal in Knowledge and its Place in Nature that knowledge is a natural kind that can be elucidated and understood in scientific terms. Central to Kornblith’s development of this proposal is the claim that there is a single category of unreflective knowledge that is studied by cognitive ethologists and is the proper province of epistemology. This claim is challenged on the grounds that even unreflective knowledge in language-using humans reflects forms of logical reasoning that are in principle unavailable to nonlinguistic animals.     

Clinically Significant Change After Cognitive Restructuring for Adult Survivors of Childhood Sexual Abuse

This study investigated the outcome of cognitive restructuring for adult survivors of childhood sexual abuse in terms of clinically significant change. Twenty-six participants were assessed for depression, State anxiety, State anger, State guilt and self-esteem before and after 10 weekly sessions of group Rational-emotive behavior therapy, and at follow-up after 8 weeks. In contrast to a previous analysis of the data in terms of statistical significance, indicating significant improvements on all variables from pre- to posttreatment, an analysis based on clinically significant change showed a differentiated treatment effect. Cognitive restructuring was found to be highly effective in facilitating recovery on anxiety, depression and anger, but less effective for guilt and low self-esteem. Only 3 patients (11, 54%) recovered on all 5 variables, while 10 patients (38, 46%) showed recovery on at least 4 variables. Relationship to the perpetrator and pre-treatment irrational evaluative beliefs (measured by means of the Survey of Personal Beliefs) were found to be the best predictors of treatment outcome. A poor response to treatment was associated with the perpetrator being a close family member and with more Other-directed Shoulds, while recovery was associated with the perpetrator being a friend or stranger and with more Awfulizing, Self-directed Shoulds and negative Self-worth beliefs.     

Occasion Setting and Drug Tolerance

There is considerable evidence that drug-paired cues become associated with drug effects. It has been hypothesized that these cues act as Pavlovian conditional stimuli (CSs), and elicit conditional compensatory responses that contribute to tolerance. On the basis of a conditioning analysis of tolerance, we would expect that it should be possible to establish drug-paired cues as occasion setters, as well as conditional stimuli. Using feature-positive discrimination training, we evaluated the contribution of occasion-setting stimuli (as well as CSs) to tolerance to the hypothermic effect of ethanol in rats. The results indicated that a complete associative analysis of drug tolerance should incorporate not only the CS properties of predrug cues, but also the occasion-setting properties of such cues. The findings have implications for interpreting conflicting findings concerning extinction of tolerance and for cue-exposure treatments of addiction.     

Potential negative consequences of mindfulness in the moral domain

Mindfulness is a state of paying conscious and nonjudgmental attention to present-moment experiences. Previous research relates this state to more effective emotion regulation and less emotion reactivity. We therefore hypothesized an attenuating effect of a mindfulness exercise on moral reactions that usually results from a bad conscience when having caused harm. Across five studies, we experimentally induced mindfulness via a short breathing exercise and then assessed harm-based moral reactions. As hypothesized, participants in the mindfulness (vs. control) exercise condition showed (i) attenuated repair intentions after having read a scenario in which participants caused harm to a friend (Study 3) and (ii) attenuated intentions to change harm-causing eating habits (Study 4). Results of Studies 1, 2 and 5 did not provide evidence for our hypothesis. A following meta-analysis across all five studies yielded an overall significant effect of mindfulness in the harm-condition, providing preliminary evidence for a potential downside to mindfulness.     

Unravelling the Interplay Between Genetic and Environmental Contributions in the Unfolding of Personality Differences from Early Adolescence to Young Adulthood

In two studies, we examined the genetic and environmental sources of the unfolding of personality trait differences from childhood to emerging adulthood. Using self‐reports from over 3000 representative German twin pairs of three birth cohorts, we could replicate previous findings on the primary role of genetic sources accounting for the unfolding of inter‐individual differences in personality traits and stabilizing trait differences during adolescence. More specifically, the genetic variance increased between early (ages 10–12 years) and late (ages 16–18 years) adolescence and stabilized between late adolescence and young adulthood (ages 21–25 years). This trend could be confirmed in a second three‐wave longitudinal study of adolescents' personality self‐reports and parent ratings from about 1400 Norwegian twin families (average ages between 15 and 20 years). Moreover, the longitudinal study provided evidence for increasing genetic differences being primarily due to accumulation of novel genetic influences instead of an amplification of initial genetic variation. This is in line with cumulative interaction effects between twins' correlated genetic makeups and environmental circumstances shared by adolescent twins reared together. In other words, nature × nurture interactions rather than transactions can account for increases in genetic variance and thus personality variance during adolescence. © 2019 European Association of Personality Psychology     

Differences in the neurocognitive profiles of professional and semi-professional male South African rugby union players

This study investigated possible cognitive functioning profile differences between professional and semi-professional rugby players. Seventy-nine male rugby union players (professional = 55, semi-professional = 24; age range = 19–37 years) participated in the study. The players completed a battery of neuropsychological functioning tests covering the following domains: memory tasks, attention and behavioural tasks, sensory-motor tasks, executive functioning tasks, verbal tasks, and emotion identification tasks. Results following Fisher’s exact test comparisons revealed no significant group differences in the cognitive functioning profiles.     

Linking organizational resources and work engagement to employee performance and customer loyalty: the mediation of service climate

This study examined the mediating role of service climate in the prediction of employee performance and customer loyalty. Contact employees (N=342) from 114 service units (58 hotel front desks and 56 restaurants) provided information about organizational resources, engagement, and service climate. Furthermore, customers (N=1,140) from these units provided information on employee performance and customer loyalty. Structural equation modeling analyses were consistent with a full mediation model in which organizational resources and work engagement predict service climate, which in turn predicts employee performance and then customer loyalty. Further analyses revealed a potential reciprocal effect between service climate and customer loyalty. Implications of the study are discussed, together with limitations and suggestions for future research.     

Explaining disproportionately high rates of adverse birth outcomes among African Americans: the impact of stress, racism, and related factors in pregnancy

Compared with European Americans, African American infants experience disproportionately high rates of low birth weight and preterm delivery and are more than twice as likely to die during their 1st year of life. The authors examine 5 explanations for these differences in rates of adverse birth outcomes: (a) ethnic differences in health behaviors and socioeconomic status; (b) higher levels of stress in African American women; (c) greater susceptibility to stress in African Americans; (d) the impact of racism acting either as a contributor to stress or as a factor that exacerbates stress effects; and (e) ethnic differences in stress-related neuroendocrine, vascular, and immunological processes. The review of literature indicates that each explanation has some merit, although none is sufficient to explain ethnic disparities in adverse birth outcomes. There is a lack of studies examining the impact of such factors jointly and interactively. Recommendations and cautions for future research are offered.     

Higher-order activity beyond the word level: cortical dynamics of simple transitive sentence comprehension

Slow electrophysiological effects, which fluctuate throughout the course of a sentence, independent of transient responses to individual words, have been reported. However, this type of activity has scarcely been studied, and with only limited use of electrophysiological information, so that the brain areas in which these variations originate have not been clearly identified. To improve this state of affairs, a principal component analysis and a modern source analysis algorithm (LORETA) were applied to the slow activity underlying transitive sentence reading. Four components explained 97.3% of the variance. Of key interest was a slow variation that occurred throughout the entire sentence but peaked with the appearance of the verb. The main solution for this component was localized in prefrontal and temporal regions presumably involved in semantic sentence processing. This constitutes empirical evidence for cortical activity--related to semantic processes thought to be involved in thematic role assignment--developing throughout the sentence but presenting a conspicuous maximum with the appearance of the verb. This finding also highlights the central role of verb information in the understanding of transitive sentences.
