Report on work in progress: “Towards a new science of the human”

A multidisciplinary and global study of the evolutionary process of the universe in general and mankind in particular is proposed, drawing from both modern science, approached by taking into consideration its various interdependent aspects; and the study of western and eastern ancient traditions, which prove to have a common foundation that is the comprehension and the control of the evolutionary process itself.

Such a study will lead to the compilation of a “Corpus Unus” of the new science of the human, a science which does not belong to a race, a culture or an age, but is specific to the human being as such.

Such a science will imply the exploration of mankind and of the evolutionary process, and applying the results in a pragmatic way to the betterment of human beings, society, and universe.     

Feedback type as a moderator of the relationship between achievement goals and feedback reactions

The aim of the current study is to shed new light on the inconsistent relationship between performance‐approach (PAp) goals and feedback reactions by examining feedback type as a moderator. Results of a field experiment (N = 939) using a web‐based work simulation task showed that the effect of achievement‐approach goals was moderated by feedback type. Relative to individuals pursuing mastery‐approach goals, individuals pursuing PAp goals responded more negatively to comparative feedback but not to task‐referenced feedback. In line with the hypothesized mediated moderation model, the interaction between achievement goals and feedback type also indirectly affected task performance through feedback reactions. Providing employees with feedback is a key psychological principle used in a wide range of human resource and performance management instruments (e.g., developmental assessment centres, multi‐source/360° feedback, training, selection, performance appraisal, management education, computer‐adaptive testing, and coaching). The current study suggests that organizations need to strike a balance between encouraging learning and encouraging performance, as too much emphasis on comparative performance (both in goal inducement and in feedback style) may be detrimental to employees' reactions and rate of performance improvement.     

Dominant achievement goals of older workers and their relationship with motivation-related outcomes

The aim of this study was to increase our insight into older employees' achievement motivation by examining the prevalence of dominant achievement goals among a “unique” group of 172 Dutch workers who remained active after their post-statutory retirement age. Moreover, we investigated how their dominant achievement goals were linked to motivation-related outcomes (i.e., work engagement and meaning of work). Our results showed that, relative to younger workers, a significantly higher amount of older workers endorsed dominant mastery-avoidance goals. In addition, as expected, older workers with dominant mastery-approach goals scored highest, while the workers with dominant mastery-avoidance goals scored lowest in work engagement, social and personal meaning of work. Theoretical as well as practical implications of these results are discussed.     

Depressive symptoms and unmitigated communion in support providers

In this research, we argue and demonstrate that the association between enacted (un)supportive behaviour and depressive symptoms is a function of the providers' levels of unmitigated communion (UC). UC is characterized by overinvolvement in others' problems, self‐neglect and externalized self‐evaluation. These characteristics appear to predispose individuals high in UC to experience depressive symptoms. As anticipated, we show that enacted supportive behaviour was negatively associated with depressive symptoms (Study 1 and 2), and enacted unsupportive behaviour was positively associated with depressive symptoms (Study 2), but only among individuals low in UC. Our findings are consistent with the idea that for high UC individuals, enacting supportive behaviour, or not enacting unsupportive behaviour, is insufficient to reduce their high levels of depressive symptoms.

Psychiatric nurses' experiences with inpatient aggression

Using a survey instrument, the experiences of psychiatric nurses with inpatient aggression were investigated in East London, U.K. On this “Perceptions of Prevalence Of Aggression Scale” (POPAS), annual experiences with 15 types of disruptive and aggressive behavior were rated anonymously. Staff members were also asked to disclose the number of days missed from work due to inpatient violence. On the basis of these POPAS forms, internal consistency of the instrument, mean reported aggression frequencies, and days missed from work due to violence were calculated. Internal consistency of the POPAS appeared to be reasonable. Verbal abuse and threats were experienced by most of the psychiatric nurses during a one‐year period (i.e., by about 80–90 percent of nurses). Sexual harassment or intimidation was also experienced relatively often on an annual basis (68 percent), particularly by female and young staff members. A minority of staff members (i.e., 16 percent) had experienced severe physical violence. Although not prevalent, this type of behavior was most strongly connected with reporting sick. In particular, staff members working with involuntarily admitted patients experienced much (severe) violence during their work. Although the validity of estimates of aggression prevalence with the POPAS instrument needs to be investigated further, such a survey may be helpful in gaining insight rather quickly into the level of day‐to‐day contact with aggressive behavior. Also, since information on verbal, physical, and sexual violence, and on days missed from work, can be provided anonymously, this rather delicate, but essential management information, may be accessed relatively easily with the POPAS.

Cortical plasticity associated with stuttering therapy

Neuroimaging studies have indicated that persistent developmental stuttering (PDS) may be associated both with an abnormality in white matter of left-hemispheric speech areas and a right-hemispheric hyperactivity. The latter may compensate for the deficient structural connectivity in the left hemisphere. To investigate the effects of stuttering therapy on brain activity nine male adults with PDS underwent functional magnetic resonance imaging (fMRI) before and within 12 weeks after fluency shaping therapy. Brain response differences during overt sentence reading before and after therapy were assessed by utilizing random effects analyses. After therapy, a more widespread activation was observed in frontal speech and language regions and temporal areas of both hemispheres, particularly and more pronounced on the left side. Interestingly, distinct posttreatment left-sided activation increases were located directly adjacent to a recently detected area of white matter anomaly [M. Sommer, M.A. Koch, W. Paulus, C. Weiller, C. Buchel (2002). Disconnection of speech-relevant brain areas in persistent developmental stuttering. The Lancet, 360, 380-383] suggesting that fluency shaping techniques reorganize neuronal communication between left-sided speech motor planning, motor execution, and temporal areas. Hence, a therapeutic mechanism can be assumed to remodel brain circuitry close to the source of the dysfunction instead of reinforcing compensation via homologous contralateral brain networks. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to: (1) describe brain activation changes detected shortly after fluency-shaping therapy; (2) identify left-hemispheric regions where a (re)functionalization after fluency-shaping therapy seems to occur adjacent to a recently described abnormal white matter region in PDS subjects; and (3) discuss how an effective cerebral compensation mechanism for stuttering could work.     

Reconstruing the "reconstruction" of psychopathy: a comment on Cooke, Michie, Hart, and Clark

In this comment we highlight critical problems in the estimation of parameters for their hierarchical three-factor model of psychopathy, as assessed with the Hare Psychopathy Checklist, and their interpretation of these factors as causally related to socially deviant behavior. We argue that there is nothing "causal" about a model in which cross-sectional data are used to assert that antisocial tendencies are consequences of other more fundamental psychopathic traits. We present an equally viable model, based on the PCL-R four-factor solution, in which antisocial tendencies play a fundamental role in the construct of psychopathy, consistent with previous research and clinical tradition.     

A novel approach to assessing achievement goals in the context of the 2 x 2 framework: identifying distinct profiles of individuals with different dominant achievement goals

In two studies, individuals' dominant achievement goals were assessed using a new, simple, and conceptually precise measure based on Elliot and McGregor's (2001) 2 x 2 framework. Next, the four groups were compared in terms of achievement-relevant variables, including need for achievement, perfectionism, perceived competence, interest, and graded performance. As expected, a very high percentage (approximately 85%) of people indicated they had a dominant achievement goal. Furthermore, the results suggest that individuals with different dominant achievement goals have clear, distinct profiles that can be characterized as positively valenced (mastery-approach), both positively and negatively valenced (performance-approach), negatively valenced (performance-avoidance), or neither positively nor negatively valenced (mastery-avoidance).     

Contributions of impulsivity and callousness in the assessment of adjudicated male adolescents: a prospective study

This study examined whether delinquent adolescents with low scores on personality scales related to callousness and impulsivity would show less antisocial behavior and better psychosocial functioning compared to those elevated on 1 or both scales. A group of 162 White and African American male adolescents, recently adjudicated in a southern youth court system, were assessed at baseline and at 18-month follow-up. Dependent variables included measures of antisocial and prosocial behaviors, days detained in juvenile detention, and symptoms of psychopathology. As hypothesized, adolescents low on both callousness and impulsivity spent fewer days detained and reported less antisocial behavior and fewer symptoms of psychopathology compared to those high on I or both scales. Finally, African American participants were detained for more days, but did not report significantly more antisocial behaviors or symptoms of psychopathology compared to the White adolescents. The results suggest that being low on callousness and impulsivity may serve a protective role for future delinquent behavior for both African American and White adolescents.     

IQ on the rise: the Flynn effect in rural Kenyan children

Abstract - Multiple studies have documented significant IQ gains over time, a phenomenon labeled the Flynn effect. Data from 20 industrialized nations show massive IQ gains over time, most notably in culturally reduced tests like the Raven's Progressive Matrices. To our knowledge, however, this is the first study to document the Flynn effect in a rural area of a developing country. Data for this project were collected during two large studies in Embu, Kenya, in 1984 and 1998. Results strongly support a Flynn effect over this 14-year period, with the most significant gains found in Raven's matrices. Previously hypothesized explanations (e.g., improved nutrition; increased environmental complexity; and family, parental, school, and methodological factors) for the Flynn effect are evaluated for their relevance in this community, and other potential factors are reviewed. The hypotheses that resonate best with our findings are those related to parents' literacy, family structure, and children's nutrition and health.
