The edge of chaos: A nonlinear view of psychoanalytic technique

The field of nonlinear dynamics (or chaos theory) provides ways to expand concepts of psychoanalytic process that have implications for the technique of psychoanalysis. This paper describes how concepts of “the edge of chaos,” emergence, attractors, and coupled oscillators can help shape analytic technique resulting in an approach to doing analysis which is at the same time freer and more firmly based in an enlarged understanding of the ways in which psychoanalysis works than some current recommendation about technique. Illustrations from a lengthy analysis of an analysand with obsessive‐compulsive disorder show this approach in action.     

The cellular mechanisms of memory are modified by experience

The N-methyl-D-aspartate receptor (NMDAR) is thought to be essential for synaptic plasticity and learning. However, recent work indicates that the role of this receptor depends on the prior history of the research subject. For example, animals trained on a hippocampus-dependent learning task are subsequently able to acquire new information in the absence of NMDAR activation. The current experiments were designed to identify the types of experiences that lead to NMDAR-independent learning. Using contextual fear conditioning in mice, we find that NMDAR-independent learning is only observed when (1) animals are trained on the same behavioral task and (2) initial learning is successfully encoded into long-term memory.     

Empowering or oppressing? Development and exploration of the Enjoyment of Sexualization Scale

Sexualization of girls and women in America is rampant and has many negative consequences. Women, however, often report enjoying being sexually admired by men. Given this paradox, it is unclear whether such enjoyment represents an authentic empowerment of women's sexuality or is related to traditional feminine norms and sexist beliefs. In Studies 1 and 2, the authors developed and tested the eight-item Enjoyment of Sexualization Scale (ESS). It had good reliability and was differentiated from related constructs including body surveillance, body shame, self-sexualizing behaviors, and appearance-contingent self-esteem. In Study 3, endorsement of traditional gender norms, endorsement of benevolent sexism, and endorsement of hostile sexism were all positively related to the ESS. Moreover, women who both enjoyed sexualization and engaged in self-objectification reported more negative eating attitudes. Overall, there was little support for positive effects of enjoying sexualization. The extent to which enjoying sexualization actually empowers women or contributes to their oppression is discussed.     

Endogenous estradiol is associated with verbal memory in nondemented older men

This study examined the relationship between endogenous hormones and cognitive function in nondemented, ethnically-diverse community-dwelling older men enrolled in the Einstein Aging Study (EAS). All eligible participants (185 men, mean age=81 years) received neuropsychological assessment (Free and Cued Selective Reminding Test (FCSRT), Logical Memory (LM), Trail Making Test B (TMTB), block design (BD)) and provided blood samples for hormonal assays (total estradiol, total testosterone, calculated free testosterone index). Linear regression analysis adjusted for age, education, body mass index, and cardiovascular comorbidities indicated that men with high levels of total estradiol demonstrated better FCSRT verbal memory performance (β=0.17, p<0.02) compared to men with lower levels of total estradiol. The results remained unchanged when the model was further adjusted for ethnicity. We did not detect an association between testosterone and cognitive performance. These findings indicate that high levels of total estradiol in older men are associated with better performance on a cue-based, controlled learning test of verbal memory that is a sensitive predictor of dementia.     

How do you fake a personality test? An investigation of cognitive models of impression-managed responding

Because faking poses a threat to the validity of personality measures, research has focused on ways of detecting faking, including the use of response times. However, the applicability and validity of these approaches are dependent upon the actual cognitive process underlying faking. This study tested three competing cognitive models in order to identify the process underlying faking and to determine whether response time patterns are a viable method of detecting faking. Specifically, we used a within-subjects manipulation of instructions (respond honestly, make a good impression, make a specific impression) to examine whether the distribution of response times across response scale options (e.g., disagree, agree) could be used to identify faking on the NEO PI-R. Our results suggest that individuals reference a schema of an ideal respondent when faking. As a result, response time patterns such as the well-known inverted-U cannot be used to identify faking.     

Anticipating explanations in relative clause processing

We show that comprehenders’ expectations about upcoming discourse coherence relations influence the resolution of local structural ambiguity. We employ cases in which two clauses share both a syntactic relationship and a discourse relationship, and hence in which syntactic and discourse processing might be expected to interact. An off-line sentence-completion study and an on-line self-paced reading study examined readers’ expectations for high/low relative-clause attachments following implicit-causality and non-implicit causality verbs (John detests/babysits the children of the musician who…). In the off-line study, the widely reported low-attachment preference for English is observed in the non-implicit causality condition, but this preference gives way to more high attachments in the implicit-causality condition in cases in which (i) the verb’s causally implicated referent occupies the high-attachment position and (ii) the relative clause provides an explanation for the event described by the matrix clause (e.g., …who are arrogant and rude). In the on-line study, a similar preference for high attachment emerges in the implicit-causality context—crucially, before the occurrence of any linguistic evidence that the RC does in fact provide an explanation—whereas the low-attachment preference is consistent elsewhere. These findings constitute the first demonstration that expectations about ensuing discourse coherence relationships can elicit full reversals in syntactic attachment preferences, and that these discourse-level expectations can affect on-line disambiguation as rapidly as lexical and morphosyntactic cues.     

Co-regulation of movement speed and accuracy by children with heavy prenatal alcohol exposure

The study investigated how children with heavy prenatal alcohol exposure regulate movement speed and accuracy during goal-directed movements. 16 children ages 7 to 17 years with confirmed histories of heavy in utero alcohol exposure, and 21 nonalcohol-exposed control children completed a series of reciprocal tapping movements between two spatial targets. 5 different targets sets were presented, representing a range of task difficulty between 2 and 6 bits of information. Estimates of percent error rate, movement time, slope, and linear fit of the resulting curve confirmed that for goal-directed, reciprocal tapping responses, performance of the group with prenatal alcohol exposure was described by a linear function, as predicted by Fitts' law, by sacrificing movement accuracy. The index of performance was the same for the two groups: it initially increased, then leveled off for more difficult movements.
