THE WORLDWIDE BURDEN OF INFANT MENTAL AND EMOTIONAL DISORDER: REPORT OF THE TASK FORCE OF THE WORLD ASSOCIATION FOR INFANT MENTAL HEALTH

Children worldwide experience mental and emotional disorders. Mental disorders occurring among young children, especially infants (birth –3 years), often go unrecognized. Prevalence rates are difficult to determine because of lack of awareness and difficulty assessing and diagnosing young children. Existing data, however, suggest that rates of disorders in young children are comparable to those of older children and adolescents (von Klitzing, Dohnert, Kroll, & Grube, 2015 ). The lack of widespread recognition of disorders of infancy is particularly concerning due to the unique positioning of infancy as foundational in the developmental process. Both the brain and behavior are in vulnerable states of development across the first 3 years of life, with potential for enduring deviations to occur in response to early trauma and deprivation. Intervention approaches for young children require sensitivity to their developmental needs within their families. The primacy of infancy as a time of unique foundational risks for disorder, the impact of trauma and violence on young children's development, the impact of family disruption on children's attachment, and existing literature on prevalence rates of early disorders are discussed. Finally, global priorities for addressing these disorders of infancy are highlighted to support prevention and intervention actions that may alleviate suffering among our youngest world citizens.     

Attenuating the link between threatened egotism and aggression

Research has found that narcissists behave aggressively when they receive a blow to their ego. The current studies examined whether narcissistic aggression could be reduced by inducing a unit relation between the target of aggression and the aggressor. Experimental participants were told that they shared either a birthday (Study 1) or a fingerprint type (Study 2) with a partner. Control participants were not given any information indicating similarity to their partner. Before aggression was measured, the partners criticized essays written by the participants. Aggression was measured by allowing participants to give their partner loud blasts of noise through a pair of headphones. In the control groups, narcissists were especially aggressive toward their partner. However, narcissistic aggression was completely attenuated, even under ego threat, when participants believed they shared a key similarity with their partner.     

Why walkers slip: shine is not a reliable cue for slippery ground

In a series of four studies, we investigated the visual cues that walkers use to predict slippery ground surfaces and tested whether visual information is reliable for specifying low-friction conditions. In Study 1, 91% of participants surveyed responded that they would use shine to identify upcoming slippery ground. Studies 2-4 confirmed participants' reliance on shine to predict slip. Participants viewed ground surfaces varying in gloss, paint color, and viewing distance under indoor and outdoor lighting conditions. Shine and slip ratings and functional walking judgments were related to surface gloss level and to surface coefficient of friction (COF). However, judgments were strongly affected by surface color, viewing distance, and lighting conditions--extraneous factors that do not change the surface COF. Results suggest that, although walkers rely on shine to predict slippery ground, shine is not a reliable visual cue for friction. Poor visual information for friction may underlie the high prevalence of friction-related slips and falls.     

Remembering all that and then some: Recollection of autobiographical memories after a 1-year delay

We have previously shown that repeated retrievals of remote autobiographical memories over the course of one month led to an overall increase in reported detail (Nadel, Campbell, & Ryan, 2007). The current study examined the retrieval of those same memories 1 year later in order to determine whether the level of detail remained stable or whether the memories returned to their original state. Participants reported even more details than they had recalled at least 1 year earlier, including new details that were reported for the first time. This finding was consistent across both multiple and single retrieval conditions, suggesting that the critical factor leading to the increase in recall was the passage of time. These findings provide evidence for long-term effects of repeated retrieval on memory content.     

Importance of having agreeable friends in adolescence (especially when you are not)

Using the actor–partner interdependence model, we examined whether adolescent's agreeableness, best friend's agreeableness, and the interaction between adolescent‐friend agreeableness are important for interpersonal functioning. Adolescents (N = 158) in fifth to eighth grades who were part of best friend pairs completed personality and friendship measures. Adolescents' adjustment and victimization experiences were assessed by peer nominations. For boys, best friend's agreeableness moderated the relationship between the target boy's agreeableness and overt victimization, relational victimization, and externalizing problems. For girls, best friend's agreeableness moderated the relationship between the target girl's agreeableness and internalizing problems and prosocial skills. This study provides an initial glimpse into how traits of friends can influence outcomes beyond what would be expected from adolescents' personality alone.     

Validity and Stability of the Youth Psychopathic Traits Inventory in a Nonforensic Sample of Young Adults

Scores were obtained for 103 Subjects on the Sixteen Personality Factor test, Form C; the Edwards Personal Preference Schedule; the Otis Quick Scoring Test, Form G; Raven's Progressive Matrices, Sets A-E; and on 47 handwriting variables. First, personality and intelligence variables, then handwriting variables were factored and rotated, after which factor scores were obtained. Through a regression of handwriting from personality and intelligence factor scores, it was found that 6 of 16 handwriting factors could be predicted by 5 of 10 personality and intelligence factors. These results and their relation to graphology are discussed.     

Impulsivity,sensation seeking and reproductive behaviour: A life history perspective

Impulsivity has often been invoked as a proximate driver of different life-history strategies. However, conceptualisations of “impulsivity” are inconsistent and ambiguities exist regarding which facets of impulsivity are actually involved in the canalisation of reproductive strategies. Two variables commonly used to represent impulsivity were examined in relation to reproductive behaviour. Results demonstrated that sensation seeking was significantly related to strategy-based behaviour, but impulsivity (defined as a failure to deliberate) was only weakly correlated. The effect of impulsivity disappeared when sensation seeking was controlled. Sex differences emerged for sensation seeking but not impulsivity. We conclude that “impulsivity” is not a unitary trait and that clearer distinctions should be made between facets of this construct.
