Callous-Unemotional Traits Only Versus the Multidimensional Psychopathy Construct as Predictors of Various Antisocial Outcomes During Early Adolescence

The aim of this study was to compare callous-unemotional (CU) traits versus the multidimensional psychopathy construct in their ability to predict future and stable antisocial behavior. At baseline, a community sample of 996 Cypriot 12-year old adolescents (52% girls) completed measures that tap conduct problems (CP) and psychopathic traits, including CU. CP, aggression, and substance use were self-reported at 1–3 year follow-ups. Youths were assigned to six mutually exclusive groups based on their baseline levels of CP and psychopathic traits. Youth with CP scoring high on all three psychopathic traits dimensions (Psychopathic Personality?+?CP) showed the most robust and highest risk for future and stable CP, aggression, and substance use, followed by youth who were high on all three psychopathic traits dimensions but displayed no concurrent CP (Psychopathic Personality Only) and CP youth with low levels of psychopathic traits (CP Only). Youth with CP who merely manifested callous-unemotional traits (Callous-Unemotional?+?CP) were only at risk for future CP. The findings suggest that the CU traits-based approach for subtyping children with CP is less informative compared to a subtyping approach using various psychopathic traits dimensions in predicting future and stable forms of various antisocial outcomes. These findings and their consistency with prior work indicate the need for additional research to examine the various psychopathic traits dimensions rather than focusing solely on CU traits, especially for CP subtyping purposes.     

Psychopathic Traits in Adolescence: the Importance of Examining Components in Face Processing,Voice Processing,and Emotional Skill

This study examined relations among interpersonal, affective, and impulsive-irresponsible psychopathic traits, emotional capacities, and recidivism rates in 144 detained adolescents. Emotional skill was conceptualized using a range of constructs, including face and voice processing, emotional intelligence, and self-reported cognitive and affective empathy. In addition, the relation between these concepts and recidivism three years after the initial assessment was examined. Results indicated that interpersonal traits were positively associated with better facial identification of fearful faces, whereas affective traits were associated with worse facial identification of sad and happy faces as well as angry voices. Impulsive-irresponsible traits were associated with reduced emotional intelligence. Differential predictive utility of the three psychopathic traits dimensions was also evidenced. Findings highlight the need to consider the broad concept of psychopathy, but also its underlying dimensions.     

Temporal compression in episodic memory for real-life events

Remembering an event typically takes less time than experiencing it, suggesting that episodic memory represents past experience in a temporally compressed way. Little is known, however, about how the continuous flow of real-life events is summarised in memory. Here we investigated the nature and determinants of temporal compression by directly comparing memory contents with the objective timing of events as measured by a wearable camera. We found that episodic memories consist of a succession of moments of prior experience that represent events with varying compression rates, such that the density of retrieved information is modulated by goal processing and perceptual changes. Furthermore, the results showed that temporal compression rates remain relatively stable over one week and increase after a one-month delay, particularly for goal-related events. These data shed new light on temporal compression in episodic memory and suggest that compression rates are adaptively modulated to maintain current goal-relevant information.     

TDQ-60 – a color picture-naming test for adults and elderly people: validation and normalization data

Word-finding difficulties are usually assessed with picture-naming tests. In this article, we present the TDQ-60, a new test designed to assess acquired lexical access deficits, taking into account semantics and psycholinguistic variables. The article includes three studies. Study 1 describes the development phase of the TDQ-60. In study 2, healthy control participants and individuals with a diagnosis of the semantic variant of primary progressive aphasia were assessed to establish the convergent and discriminant validity of the TDQ-60. Finally, in Study 3, a group of 305 young and elderly French-speaking adults from Quebec were assessed in order to provide normative data. The results demonstrate that the TDQ-60 has good convergent validity and good discriminant validity. This study also provides normative data in which were considered the effect of age and education.The TDQ-60 is a new valid picture-naming test, controlled for psycholinguistic variables and designed to identify the influence of semantics on lexical access in spoken production.     

The influences of tropical climate on imagined walking time

This study investigated the effects of a Tropical Climate (TC) on actual and imagined walking times. Participants had to execute and imagine walking 3 distances with or without a 10-kg weight in either a TC or an Air Conditioning (AC) condition. The motor imagery quality was evaluated by computing the isochrony index. The results revealed that movement times were shorter for imagined walking than for actual walking and increased with the distance of the paths in both cases. By contrast, the effect of the load increased actual walking times for the 10- and 15-meter distances without affecting imagined walking times. Importantly, the isochrony index was negatively affected by the increase in load and distance and the effects of distance were amplified in a TC. These findings showed that the environmental climate in which motor imagery arises can modulate the subject’s ability to build up the temporal characteristics of simulated actions.     

Baselining affects the production of deceptive narratives

Recent research shows that the quality of a baseline (i.e., the analysis of one's behavior in normal conditions) decreases when the second narrative is expected and deceitful. However, a first step would be to investigate whether the writing of a first narrative might influence the second, independently of its expectancy. In this study, we hypothesized that second narratives would be less detailed, especially if these narratives are deceptive. Participants (N = 71) were asked to narrate two consecutive truthful and deceptive narratives. The second narrative was unexpected, and the order of the narratives was counterbalanced. Results suggest a detrimental effect of deceptiveness and order on the frequency of details. Moreover, an interaction was observed, suggesting when narratives are written after a first one, the frequency of details decreases, all the more if they were deceptive. The results of this experiment are discussed from both a theoretical and an applied perspective.     

Prevalence and determinants of direct and generative modes of production of episodic future thoughts in the word cueing paradigm

Recent research suggests that episodic future thoughts can be formed through the same dual mechanisms, direct and generative, as autobiographical memories. However, the prevalence and determinants of the direct production of future event representations remain unclear. Here, we addressed this issue by collecting self-reports of production modes, response times (RTs), and verbal protocols for the production past and future events in the word cueing paradigm. Across three experiments, we found that both past and future events were frequently reported to come directly to mind in response to the cue, and RTs confirmed that events were produced faster for direct than for generative responses. When looking at the determinants of direct responses, we found that most past and future events that were directly produced had already been thought of on a previous occasion, and the frequency of previous thoughts predicted the occurrence of direct access. The direct production of autobiographical thoughts was also more frequent for past and future events that were judged important and emotionally intense. Collectively, these findings provide novel evidence that the direct production of episodic future thoughts is frequent in the word cueing paradigm and often involves the activation of personally significant “memories of the future.”     

Attachment and temperament in early childhood; implications for later behavior problems

In the context of a French validation study, the Child Behavior Checklist (CBCL) was administered to more than 3000 French speaking mothers of 5‐year‐old children. Scores were factor‐analyzed. Principal components analysis revealed four dimensions: externalizing and internalizing behavior problems, immaturity and somatoform disorders. Another sample of 40 mothers participated in a longitudinal study, filling in the CBCL when their children were 5 years old. These children had been observed previously in the Strange Situation (SSP) at 21 months. Several dichotomous variables derived from the SSP (e.g. secure versus insecure, proximal versus distal interaction with the mother, avoidant behavior) have been used as predictors of the four dimensions extracted from the CBCL. Hierarchical regressions showed that proximal behaviors with the mother, which reflect temperamental characteristics independently of the quality of attachment, predicted internalizing problems, whereas avoidance of the mother, or insecure–avoidant attachment, predicted internalizing as well as externalizing problems at 5 years of age. These results show that attachment and temperament, as assessed by the SSP, may each have specific implications for later behavior problems. Copyright © 2000 John Wiley & Sons, Ltd.     

When History Seems to Repeat Itself: Exposure to Perceived Lessons of the Past Influences Predictions About Current Political Events

The idea that the past holds lessons for the present, under the guise of historical analogies, is prevalent in political and public discourse. Those analogies are often accompanied by dire warnings befalling those who “forget” or otherwise neglect the powerful lessons of History—and would then be “doomed to repeat it”, as the saying goes. So, Would remembering history make it seem more OR LESS likely to repeat itself in the future? In other words, does exposure to specific lessons about past events, especially ones involving causal claims, affect how people expect real-life events to turn out? Four studies (three preregistered) tested this experimentally. In Studies 1 and 2, participants expected the same behavior (the US adopting a harsh stance against Iran in the Nuclear Treaty) to result in a more negative outcome when this current stance seemed to match a “lesson” they had read about the break-out of World War II (European leaders adopting a harsh approach against Germany in the 1919 Versailles Treaty vs. a conciliatory approach in the 1938 Munich Agreement). Studies 3 and 4 attempted to eliminate some confounds present in the first two studies and to generalize the effect to different events. While results varied across studies, an internal meta-analysis indicated that the analogical effect on predictions (d = –.08) tended to become stronger as participants’ knowledge about the target situation decreased (d-1SD = –.24). These findings support the possibility of analogical-based predictive effects for real-life political events, and are discussed in light of their research and political implications.     

Complex and subtle structural changes in prefrontal cortex induced by inhibitory control training from childhood to adolescence

A number of training interventions have been designed to improve executive functions and inhibitory control (IC) across the lifespan. Surprisingly, no study has investigated the structural neuroplasticity induced by IC training from childhood to late adolescence, a developmental period characterized by IC efficiency improvement and protracted maturation of prefrontal cortex (PFC) subregions involved in IC. The aim of the present study was to investigate the behavioral and structural changes induced by a 5‐week computerized and adaptive IC training in school‐aged children (10‐year‐olds) and in adolescents (16‐year‐olds). Sixty‐four children and 59 adolescents were randomly assigned to an IC (i.e. Color‐Word Stroop and Stop‐Signal tasks) or an active control (AC) (knowledge‐ and vocabulary‐based tasks) training group. In the pre‐ and posttraining sessions, participants performed the Color‐Word Stroop and Stop‐signal tasks, and an anatomical resonance imaging (MRI) was acquired for each of them. Children's IC efficiency improved from the pre‐ to the posttraining session in boys but not in girls. In adolescents, IC efficiency did not improve after IC training. Similar to the neuroplastic mechanisms observed during brain maturation, we observed IC training‐related changes in cortical thickness and cortical surface area in several PFC subregions (e.g. the pars opercularis, triangularis, and orbitalis of the inferior frontal gyri) that were age‐ and gender‐specific. Because no correction for multiple comparisons was applied, the results of our study provide only preliminary evidence of the complex structural neuroplastic mechanisms at the root of behavioral changes in IC efficiency from pre‐ to posttraining in school‐aged children and adolescents.
