Risk factors for medically serious suicide attempts: evidence for a psychodynamic formulation of suicidal crisis

This study explored a psychodynamic model for suicide risk by examining risk factors for medically serious suicide attempts, including assessments of affect flooding, negative self-schema / fragmentation, and impaired reality testing, closely approximating Maltsberger's psycho-dynamic formulation of suicide crisis. Baseline risk factors including age, gender, psychiatric symptoms, high-risk behaviors, and the Implicit Risk for Suicide Index (IRSI) were used to detect medically serious suicide attempts monitored for up to a year after the assessment. Twenty-five psychiatric inpatients who made life-threatening suicide attempts after assessment were compared to 25 inpatients and 25 psychotherapy outpatients who made no suicide attempts during follow-up. Statistical analysis revealed that a history of at least one suicide attempt and elevated IRSI scores accounted for 60 percent of the variance in detecting medically serious suicide attempts. Elevated IRSI accurately identified suicide attempt status above and beyond past suicide attempts and other empirically validated risk factors. Results are discussed in light of psychodynamic formulations of suicide risk.     

Mere belonging: the power of social connections

Four experiments examined the effect on achievement motivation of mere belonging, a minimal social connection to another person or group in a performance domain. Mere belonging was expected to increase motivation by creating socially shared goals around a performance task. Participants were led to believe that an endeavor provided opportunities for positive social interactions (Experiment 1), that they shared a birthday with a student majoring in an academic field (Experiment 2), that they belonged to a minimal group arbitrarily identified with a performance domain (Experiment 3), or that they had task-irrelevant preferences similar to a peer who pursued a series of goals (Experiment 4). Relative to control conditions that held constant other sources of motivation, each social-link manipulation raised motivation, including persistence on domain-relevant tasks (Experiments 1-3) and the accessibility of relevant goals (Experiment 4). The results suggest that even minimal cues of social connectedness affect important aspects of self.     

The hierarchical structure of childhood personality in five countries: continuity from early childhood to early adolescence

Childhood personality is a rapidly growing area of investigation within individual differences research. One understudied topic is the universality of the hierarchical structure of childhood personality. In the present investigation, parents rated the personality characteristics of 3,751 children from 5 countries and 4 age groups. The hierarchical structure of childhood personality was examined for 1-, 2-, 3-, 4-, and 5-factor models across country (Canada, China, Greece, Russia, and the United States) and age group (3-5, 6-8, 9-11, and 12-14 years of age). Many similarities were noted across both country and age. The Five-Factor Model was salient beginning in early childhood (ages 3-5). Deviations across groups and from adult findings are noted, including the prominent role of antagonism in childhood personality and the high covariation between Conscientiousness and intellect. Future directions, including the need for more explicit attempts to merge temperament and personality models, are discussed.     

Explicit and implicit approach motivation interact to predict interpersonal arrogance

Self-reports of approach motivation are unlikely to be sufficient in understanding the extent to which the individual reacts to appetitive cues in an approach-related manner. A novel implicit probe of approach tendencies was thus developed, one that assessed the extent to which positive affective (versus neutral) stimuli primed larger size estimates, as larger perceptual sizes co-occur with locomotion toward objects in the environment. In two studies (total N = 150), self-reports of approach motivation interacted with this implicit probe of approach motivation to predict individual differences in arrogance, a broad interpersonal dimension previously linked to narcissism, antisocial personality tendencies, and aggression. The results of the two studies were highly parallel in that self-reported levels of approach motivation predicted interpersonal arrogance in the particular context of high, but not low, levels of implicit approach motivation. Implications for understanding approach motivation, implicit probes of it, and problematic approach-related outcomes are discussed.     

Affective state influences perception by affecting decision parameters underlying bias and sensitivity

Studies of the effect of affect on perception often show consistent directional effects of a person's affective state on perception. Unpleasant emotions have been associated with a "locally focused" style of stimulus evaluation, and positive emotions with a "globally focused" style. Typically, however, studies of affect and perception have not been conducted under the conditions of perceptual uncertainty and behavioral risk inherent to perceptual judgments outside the laboratory. We investigated the influence of perceivers' experienced affect (valence and arousal) on the utility of social threat perception by combining signal detection theory and behavioral economics. We compared 3 perceptual decision environments that systematically differed with respect to factors that underlie uncertainty and risk: the base rate of threat, the costs of incorrect identification threat, and the perceptual similarity of threats and nonthreats. We found that no single affective state yielded the best performance on the threat perception task across the 3 environments. Unpleasant valence promoted calibration of response bias to base rate and costs, high arousal promoted calibration of perceptual sensitivity to perceptual similarity, and low arousal was associated with an optimal adjustment of bias to sensitivity. However, the strength of these associations was conditional upon the difficulty of attaining optimal bias and high sensitivity, such that the effect of the perceiver's affective state on perception differed with the cause and/or level of uncertainty and risk.     

Differentiation of Self in Family Members’ of SUD Loved Ones: An Analysis of Prefrontal Cortex Activation

Substance use disorders (SUDs) are a chronic disease that impacts the individual with a SUD as well as an entire family system. While family members of those with SUDs are one of the most important support networks in the recovery process, impacted family members have been found to experience more adverse health outcomes and altered functioning of the prefrontal cortex (PFC). These impacts negatively influence not only family members’ personal health but also the health of the family unit, which limits the family’s capability of providing its most effective support. Bowen’s conceptualization of differentiation of self can help explain the perspective of SUDs as a “family disease” and associated impacts on family members. Using functional near-infrared spectroscopy with a sample of 26 SUD-impacted family members, the present study examined associations between PFC activation in response to images of a loved-one seeking abstinence from a SUD and various components of differentiation of self (i.e., emotional cutoff, emotional reactivity, fusion with others, and I-position). Activation of the left dorsomedial PFC in response to SUD loved-one images associated negatively with emotional reactivity and positively with fusion with others. These findings did not replicate in a control group and have important implications for research and clinical practice.

     

Change occurs when body meets environment: A review of the embodied nature of development

The purpose of this paper is to outline the challenges of psychological research in addressing the mechanisms of emergence: how new behavioral patterns and cognitive abilities arise from the interaction of an organism with its environment in real time. We review some of the empirical studies on infant development with reference to Dynamical Systems accounts and relevant views such as the ecological approach to perception and action, and cover topics ranging from early motor skills to goal‐directed locomotion and to higher cognitive development. The central claim is that the results of these studies are essentially related: they suggest that there is a fundamental connection among perception, motor behavior, and cognition. In addition, we recount our attempt to re‐enact the situatedness and temporal structure of the decision‐making processes of human infants by using an autonomous robotic device. We conclude by highlighting several insights from the broad spectrum of studies looking into the embodied nature of adaptive behavior. In our view, such studies are making a profound contribution to uncovering the emergent mechanisms of intellectual and bodily activity throughout development.     

Examining Anxiety and Depression as Moderators of the Associations Between ADHD Symptoms and Academic and Social Problems in Hispanic Adolescents

The effects of attention-deficit/hyperactivity disorder (ADHD) symptoms on the psychosocial functioning of Hispanic youth have been understudied. It also remains unclear if the well-established associations between ADHD symptoms and academic and social impairment are exacerbated by co-occurring internalizing symptoms. The purposes of the present study were to (1) examine whether ADHD symptoms would be associated with academic and social problems while also controlling for oppositional defiant disorder (ODD) symptoms, and (2) test the hypothesis that anxious and depressive symptoms would moderate the relations between ADHD symptoms and academic and social problems. Participants were 142 at-risk Hispanic adolescents (54 % male, ages 14–19) who reported on their anxious and depressive symptoms, as well as their teachers who reported on adolescents’ ADHD symptoms, ODD symptoms, academic problems, and social problems. When the psychopathology variables were included simultaneously in a path model, ADHD was the only domain significantly positively associated with academic problems. In contrast, ODD and depressive symptoms were the only domains significantly positively associated with social problems when all of the psychopathology variables were included in the path model. No moderation effects were found in relation to academic problems, although a significant ADHD × depression interaction was found in relation to social problems. Specifically, ADHD symptoms were not associated with social problems among adolescents who reported low levels of depressive symptoms, but the association between ADHD symptoms and social problems was significant at higher levels of depression. In addition to targeting oppositionality, attending to the combined presence of ADHD and depressive symptoms will be important for reducing the social impairments among Hispanic adolescents.
