The Disruptive Adolescent as a Grown-Up: Predicting Adult Startle Responses to Violent and Erotic Films from Adolescent Conduct Problems and Callous-Unemotional Traits

The current study aimed to identify heterogeneous groups of adolescents differing on their levels of conduct problems (CP) and callous-unemotional (CU) traits, and compare them on startle reactivity to emotional videos (violent/erotic) during young adulthood. A Latent Profile Analysis, conducted among a longitudinal sample of 2306 adolescents, provided evidence for the existence of heterogeneous CP and CU subgroups (i.e., CP-only, CU-only, and CP+CU groups). Three years later, 82 young adults (Mage?=?19.95), randomly selected from the identified groups, participated in an experiment assessing their startle eye-blink responses during violent, erotic and neutral video scenes. Self-report ratings of fear, valence and arousal to affective scenes were also collected. Findings suggested that adolescents high on CP and low on CU traits showed high startle potentiation when viewing violent scenes during young adulthood, while those high on both CP and CU traits showed diminished startle reactivity to violent stimuli. Individuals high on CU traits without CP showed similar startle reactivity to controls. Further, the findings indicate that startle potentiation to violent stimuli can be a reliable physiological marker to distinguish antisocial individuals with and without CU traits. The finding that the CU only group was not differentiated from the control group on startle reactivity when viewing violent stimuli might explain their lower likelihood of engaging in antisocial behavior.     

Searching for the “Big Five” in a Greek context: the NEO-FFI under the microscope

The five-factor inventory (FFI) is a commonly used personality test based on the NEO-personality inventory revised. It has been translated into several languages and validated in a number of countries. Using a sample of 1204 individuals, the present study evaluates the psychometric properties and factor structure of the Greek FFI and provides normative information for its use with Greek populations. Convergent validity is also assessed by studying the relationship between the five scales of the FFI and the Brief Symptom Inventory. Results show that although the factor scales had acceptable internal consistency, they were highly intercorrelated. Exploratory factor analyses failed to reproduce the appropriate factor structure, yielding instead numerous fragments of the five dimensions. Confirmatory factor analyses also failed to lend support to the five factor model of personality as measured by this instrument. Based on these results, the use of the instrument is recommended only with serious caution in this cultural context. Further research ought to decipher whether the failures to reproduce the five factor model using the FFI in this and other cultures represents a challenge to the universality of the theory, or merely a shortcoming of the specific instrument.     

Contributions of Loss Events to Loss Distress and Trauma Symptoms in Recently Resettled Refugee Women at Risk

This research examined contributions of loss events to loss distress and trauma symptoms (accounting for trauma events) for refugee women at risk. Participants (N?=?104) responded to the Multidimensional Loss Scale (loss events and distress) and Harvard Trauma Questionnaire (trauma events and symptoms). Loss events contributed uniquely to loss distress (explaining additional 50.8% variance), and made a unique contribution to trauma symptoms (explaining additional 5.2% variance) approximately equal to trauma events. Appropriate response to psychic distress in refugee women at risk requires assessment of both loss and trauma and consideration of cultural differences in ways loss is expressed and meaning ascribed to symptoms.     

Promoting Responsible Research Conduct: A South African Perspective

A great deal of effort has gone into developing capacity in the sphere of human research protection programmes in South Africa and Africa over the last decade or more, by several international organisations. However the promotion of the broader agenda of research integrity or ‘RCR’ (Responsible Conduct of Research) has lagged behind. From a global perspective South Africa and other African countries are actively involved in research endeavours and collaborations across a very broad spectrum of scientific fields. For this research to fulfil its potential social value it must be reliable and trustworthy and hence it is essential that research institutions and universities take the promotion of research integrity seriously. The purpose of this paper is to consider the role of an institutional office of research integrity within the context of academic research particularly in South Africa but also in Africa. I will reflect on my own experience over a period of five years as a research integrity officer at a South African academic institution to highlight concerns in five domains; the promotion of an ethic of responsibility in opposition to compliance and bureaucracy, collaboration ethics and collegiality especially in the context of North-South collaborations, authorship and publication ethics, the problem of plagiarism and the utility of policy and procedure. I will suggest that the establishment of such an office can be of great value in the promotion of a broad culture of research ethics and responsible research conduct. The possible role and scope of function of an institutional office of research integrity will be briefly outlined.     

The role of pragmatic principles in resolving attachment ambiguities: Evidence from eye movements

In an eyetracking experiment, participants read sentences that contained a prepositional phrase (PP) that could be attached to one of two preceding verbs. To understand the sentence, readers had to select which verb would serve as the host for the PP. In some of the sentences, the critical verbs and the PPs were part of a subordinate clause in which lexical and syntactic factors were expected to matter, but discourse factors favoring attachment of the material to positions where it would be relevant to the main assertion of the sentence were not expected to matter. In other sentences, the critical material was tested in main clause contexts in which the main assertion principle was predicted to apply. Hierarchical linear modeling showed that online attachment preferences were affected by clause type (main vs. subordinate). Specifically, the preference for a local verb over a distant verb was greater when the critical material appeared within a subordinate clause than when it appeared within a main clause. This pattern of results can be explained by the operation of the relativized relevance or main assertion principle, which in our sentences meant that participants favored attachment of the PP to the first verb over the second.     

Fighting like a girl fighting like a guy: gender identity, ideology, and girls at early adolescence

In this chapter we explore the phenomenon of "girls fighting like guys" by listening to adolescent girls' justification for physical fighting with other girls. We argue that physical girlfighting is a particular kind of gendered performance--a performance of identity that expresses, at least in part, an answer to the question, "Who am I?"--that both perpetuates and challenges the usual notions of masculinity and femininity and the differential power associated with these discourses. We present a sociocultural approach to identity that we believe not only holds promise for helping us to understand girl-fighting behavior but also highlights the clear interrelationship between social identity and personal identity. We conclude by highlighting several implications of this analysis for those who work with girls (and boys) in educational and clinical settings.     

Chronic administration of an angiotensin II receptor antagonist resets the hypothalamic-pituitary-adrenal (HPA) axis and improves the affect of patients with diabetes mellitus type 2: preliminary results

Diabetes mellitus type 2 (DM type 2) is associated with depressive symptomatology and intermittent hyperfunction of the hypothalamic-pituitary-adrenal (HPA) axis. DM type 2 is also accompanied by increased tissue levels of angiotensin II (Ang II), which stimulates the HPA axis through the Ang II type 1 receptors (AT1). We investigated the effect of candesartan, an angiotensin receptor blocker (ARB) that crosses the blood brain barrier, on the activity of the HPA axis and on the affect of 17 patients with DM type 2, aged 40-65 years, who were treated with 4 mg/day candesartan per os for at least 3 months. Before and after candesartan administration, a corticotropin-releasing hormone (CRH) stimulation test and psychological tests were performed. In response to hCRH, time-integrated secretion of ACTH was not altered by candesartan administration, however, the cortisol response was decreased significantly compared to baseline (mean +/- SEM, 2327 +/- 148.3 vs. 1943 +/- 131.9 microg/dl, P = 0.005) suggesting reduced sensitivity of the adrenals to ACTH. In parallel, there was a significant improvement in interpersonal sensitivity (0.91 +/- 0.16 vs. 0.70 +/- 0.15, P = 0.027) and depression scores (0.96 +/- 0.15 vs. 0.71 +/- 0.10, P = 0.026). We suggest that candesartan resets the HPA axis of patients with DM type 2 and improves their affect.     

Early Detection of Memory Impairment in Alzheimer’s Disease: A Neurocognitive Perspective on Assessment

We propose that the earliest neuropsychological detection of Alzheimer’s disease (AD) can be informed by current views about the neuropathogenesis of AD and cognitive models of memory and its neurobiological substrates. The primary impairment in early AD is encoding/consolidation, resulting from medial temporal lobe (MTL) pathology. On theoretical and empirical grounds, paired associate learning (PAL) appears to be the ideal paradigm for detecting MTL dysfunction in early AD. It has not been embraced as a test of choice, however, and this critical review discusses why the paradigm may have not fulfilled its potential. We suggest that a new PAL variant, ‘associate-recognition’, may prove to be clinically efficacious.     

Word acquisition, retention, and transfer: findings from contextual and isolated word training

Successful reading instruction entails not only acquiring new words but also remembering them after training has finished and accessing their word-specific representations when they are encountered in new text. We report two studies demonstrating that acquisition, retention, and transfer of unfamiliar words were affected differentially by isolated word and context training. Materials were individualized to include only those words that average readers in second grade were unable to name in context. Different words were trained in each condition; context training presented words in stories, and isolated word training presented words on flashcards. Together, the studies show that context training promotes word acquisition beyond that experienced from reading words in isolation. Contrary to the prevailing opinion, memory performance for words trained in context and in isolation did not differ; children demonstrated excellent retention over an 8-day interval in both conditions. Finally, transfer was maximized when the congruency between training and testing was high. Therefore, when reading trained words in novel circumstances, the best method of training was mediated by the transfer task employed at test.
