The relations between cognitive ability and personality: Convergent results across measures

Several studies have investigated the relations between cognitive ability and Big Five personality constructs. The present study extended previous research by (a) examining these relationships in large samples (total N = 120,014), (b) including several measures of cognitive ability and personality, (c) examining both domain and facet-level personality scores, (d) expanding the personality domains studied to include Machiavellianism, and (e) correcting the observed correlations for range restriction and reliability to provide a better statistical estimate of the relations between the cognitive and personality scores and constructs. Results were consistent with prior research showing a positive relationship between cognitive ability and Openness and negative relationships between cognitive ability and Neuroticism and Conscientiousness. Negative relations between cognitive ability and Extraversion and Agreeableness also were observed. Machiavellianism, not part of the Big Five was found to have a positive correlation with cognitive ability. Of particular interest was the finding that the relations between cognitive ability and personality were affected by the specific content of the cognitive and personality measures. Cognitive measures with verbal content were more strongly correlated with personality than were cognitive measures with math or nonverbal content for all of the samples. Also, there was considerable variability in the cognitive-personality correlations for the facets underlying each personality domain. The variability in correlations at the facet-level implies that cognitive-personality relationships at the domain-level will vary as a function of the specific content of the cognitive and personality measures. Overall, the results provide support for cognitive-personality association at the measurement level.     

A temporally distinct role for group I and group II metabotropic glutamate receptors in object recognition memory

Recognition memory, involving the ability to discriminate between a novel and familiar object, depends on the integrity of the perirhinal cortex (PRH). Glutamate, the main excitatory neurotransmitter in the cortex, is essential for many types of memory processes. Of the subtypes of glutamate receptor, metabotropic receptors (mGluRs) have received less study than NMDA receptors; thus, the reported experiments examined the role of mGluRs in familiarity discrimination in the rat PRH. Experiments 1 and 2 assessed the effects of systemic administration of MPEP, a group I mGluR (specifically mGluR5) antagonist, and/or LY341495, a group II mGluR antagonist, on a spontaneous object novelty preference task. Simultaneous antagonism of both group I and II mGluRs impaired familiarity discrimination following a 24-h but not a 15-min delay, while antagonism of either mGluR subtype alone had no effect at either delay. The impairment was in acquisition, as in Experiment 3 coadministration of MPEP and LY341495 did not affect recognition memory performance when administered either after the sample phase or prior to test. The impairment in long-term recognition memory was mediated by mGluRs in the PRH, as localized intracortical antagonism of group I and II mGluRs also produced a deficit (Experiment 4). No evidence was found for an involvement of group III mGluRs in the acquisition of long-term familiarity discrimination (Experiment 5). These findings establish that glutamatergic neurotransmission in the PRH via group I and II mGluRs is crucial for the acquisition, but not for the consolidation or retrieval of long-term object recognition memory.     

Tanya and the Adaptive Dialectic of Romantic Passion and Secure Attachment

My analytic work with Tanya illustrated one unique, heightened, individual version of a pervasive human conflict: the way in which erotic passion can be experienced as inherently conflicting with other relational bonds and broader values. In virtually every culture throughout human history, we find expressions of this tension between passionate Eros and other forms of love.

My clinical approach entails an openness to multiple analytic perspectives, including Mitchell's posthumous views in Can Love Last. In addition, I make use of a sensibility informed by evolutionary biology as a vantage point for understanding the individual struggle of patients like Tanya, as well as illuminating some of the larger issues about Eros and attachment. I suggest that romantic aspects of Eros may have evolved as part of a complex psychological system designed to deal with specifically human existential vulnerabilities and anxieties, as well as a way of challenging the inherent human tendency to over-accommodate to the subjective world of the other.     

Review Essay: Constructivism with a Human Face

Irwin Hoffman's book Ritual and Spontaneity includes, but goes well beyond, his series of seminal papers—written over the past several decades—developing a psychoanalytic, constructivist perspective. A new, existential framework depicts what Hoffman calls the “psychobiological bedrock” at the core of the human process of constructing meaning—the lifelong effort to create a livable, subjective world in face of our ever present sense of loss, suffering, and, ultimately, mortality.

This review describes Hoffman's encompassing, existential perspective and discusses how, within this framework, he uses his dialectical sensibility to frame our understanding of both parenting and analysis as “semisacred” activities. The “dialectic of ritual and spontaneity”—the vital clash between disciplined adherence to the analytic frame and personally expressive deviations from it—represents the creative tension between the “magical” dimension of analytic authority and the healing influence of a genuinely expressive human relationship. Hoffman's perspective on the self-interested, “dark side” of the analytic relationship is compared with Winnicott's views on the vital, therapeutic role of “hate” and the paradoxical process by which the patient comes to “use” the analyst.

Unlike most postmodernist “constructivists,” Hoffman openly reveals his underlying belief in certain “transcultural, transhistorical universals”—his “psychobiological bedrock.” In acknowledging these “essentials” (assumptions about human nature) that in some form are integral, yet often hidden, elements of any system of thought, Hoffman saves his own dialectical constructivism from falling into dichotomous (constructivist vs. essentialist) thinking.     

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.     

Psychometric properties of the Coping Strategy Indicator (CSI) in a study of coping behaviour amongst malawian students

Abstract

The Coping Strategy Indicator (CSI; Amirkhan 1990) is an inductively derived measure of responses to adverse circumstances. Although seeking to isolate “a few fundamental strategies with wide applicability” (Amirkhan 1990). the initial validation studies were all based on Californian populations. The present study repork findings from completion of the CSI by 415 Malawian students as part of their enrolment health check up. Factor analysis (principal components analysis with varimax rotation) identified three factors with very similar structure and loadings to those identified by Amirkhan, namely, Support Seeking, Problem Solving and Avoidance. As with the initial validation study, there was some evidence of withdrawal and distraction forming identifiable sub-components of Avoidance. The CSI does appear to provide a measure of core coping strategies which is robust across cultural settings, the theoretical implications of which are considered. The influence of factors such as age and gender on CSI scores is discussed
