I Know That my Redeemer Lives: Relational Perspectives on Trauma, Dissociation, and Faith

This paper focuses the lens of multiplicity on patients’ religious experience in relation to the psychic realities of early or pervasive trauma, where dissociation is not just a normal means of self-regulation, but becomes an entrenched structuring mechanism through which the trauma survivor experiences every relationship, including any relationship to God. What might God or faith look like from the perspective of the traumatized self? This paper considers issues of multiplicity and dissociation as they affect the processing of religious or spiritual experience, with a few brief clinical illustrations, and offers a reading of the biblical book of Job as a metaphor for the inner world of the survivor of early trauma.     

Extending parasite-stress theory to variation in human mate preferences

In this commentary we suggest that Fincher & Thornhill's (F&T's) parasite-stress theory of social behaviors and attitudes can be extended to mating behaviors and preferences. We discuss evidence from prior correlational and experimental studies that support this claim. We also reanalyze data from two of those studies using F&T's new parasite stress measures.     

A randomized controlled trial of internet-based therapy in depression

Depression is among the most prevalent disorders worldwide. In view of numerous treatment barriers, internet-based interventions are increasingly adopted to “treat the untreated”. The present trial (registered as NCT01401296) was conducted over the internet and aimed to assess the efficacy of an online self-help program for depression (Deprexis). In random order, participants with elevated depression symptoms received program access or were allocated to a wait-list control condition. After eight weeks, participants were invited to take part in an online re-assessment. To compensate for common problems of online studies, such as low completion rates and unclear diagnostic status, reminders and incentives were used, and clinical diagnoses were externally confirmed in a subgroup of 29% of participants. Relative to the wait-list group, program users experienced significant symptom decline on the Beck Depression Inventory (BDI; primary outcome), the Dysfunctional Attitudes Scale (DAS), the Quality of Life scale (WHOQOL-BREF) and the Rosenberg Self-Esteem Scale (RSE). Compared to wait-list participants, symptom decline was especially pronounced among those with moderate symptoms at baseline as well as those not currently consulting a therapist. Completion (82%) and re-test reliability of the instruments (r = .72–.87) were good. The results of this trial suggest that online treatment can be beneficial for people with depression, particularly for those with moderate symptoms.     

Perirhinal cortex resolves feature ambiguity in configural object recognition and perceptual oddity tasks

The perirhinal cortex (PRh) has a well-established role in object recognition memory. More recent studies suggest that PRh is also important for two-choice visual discrimination tasks. Specifically, it has been suggested that PRh contains conjunctive representations that help resolve feature ambiguity, which occurs when a task cannot easily be solved on the basis of features alone. However, no study has examined whether the ability of PRh to resolve configural feature ambiguity is related to its role in object recognition. Therefore, we examined whether bilateral excitotoxic lesions of PRh or PPRh (perirhinal plus post-rhinal cortices) in the rat would cause deficits in a configural spontaneous object recognition task, and a configural simultaneous oddity discrimination task, in which the task could not be solved on the basis of features, but could only be solved using conjunctive representations. As predicted by simulations using a computational model, rats with PPRh lesions were impaired during a minimal-delay configural object recognition task. These same rats were impaired during a zero-delay configural object recognition task. Furthermore, rats with localized PRh lesions were impaired in a configural simultaneous oddity discrimination task. These findings support the idea that PRh contains conjunctive representations for the resolution of feature ambiguity and that these representations underlie a dual role for PRh in memory and perception.     

Physical Attractiveness Bias in Employee Termination

We examined the impact of attractiveness on employment termination decisions. After viewing a file that contained a poor performance review and a badge with a photograph of an extremely attractive, moderately attractive, or unattractive employee, 178 participants were asked if they would terminate the employee, rated how much they liked the employee, and made a judgment of attribution of her poor performance. Participants were willing to terminate the unattractive woman more frequently than the moderate or extremely attractive women. The participants also liked the unattractive woman less than the others. When asked to rate causes of poor performance, no differences were found based directly on attractiveness, but attributions mediated the relationship between liking ratings and termination decisions.     

Assessing executive abilities following acute stroke with the trail making test and digit span

The Trail Making Test and Digit Span are neuropsychological tests widely used to assess executive abilities following stroke. The Trails B and Digits Backward conditions of these tests are thought to be more sensitive to executive impairment related to frontal lobe dysfunction than the Trails A and Digits Forward conditions. Trails B and Digits Backward are also thought to be more sensitive to brain damage in general. Data from the Stroke and Lesion Registry maintained by the Washington University Cognitive Rehabilitation Research Group were analyzed to compare the effects of frontal versus nonfrontal strokes and to assess the effects of stroke severity. Results showed that the performance of patients with frontal and nonfrontal strokes was comparable in each condition of both the Trail Making Test and Digit Span, providing no support for the widely held belief that Trails B and Digits Backward are more sensitive to frontal lobe damage. Further, Trails A was as strongly correlated with stroke severity as Trails B, whereas Digits Backward was more strongly correlated with stroke severity than Digits Forward. Overall, the Trail Making Test and Digit Span are sensitive to brain damage but do not differentiate between patients with frontal versus nonfrontal stroke.     

Predictors and consequences of sudden gains in transdiagnostic cognitive-behavioural therapy for anxiety disorders

Sudden gains—substantial stable symptom improvements between consecutive therapy sessions—are a common phenomenon. As condensed points of change, examination of sudden gains can provide insight into mechanisms of therapeutic change. This study investigated the association between sudden gains and cognitive change, therapeutic alliance, and/or client engagement in transdiagnostic group cognitive-behavioural therapy for anxiety disorders. Of 58 treatment initiators, 21% (n = 12) exhibited a sudden gain. Consistent with previous research, sudden gainers demonstrated significantly greater pre- to post-treatment symptom improvement than non-sudden gainers. Observational coding of therapy sessions found that sudden gains were associated with elevated levels of cognitive change and client engagement in the pre-gain session, and elevated levels of cognitive change and therapeutic alliance in the post-gain session. However, these results varied by use of within- and between-subject control comparisons, highlighting the value using a dual control methodology. In context of previous research, the results on cognitive change replicate previous findings in depressive populations, and clarify mixed findings in anxiety populations. The results on therapeutic alliance replicate previous findings for the first time in an anxiety sample, although the between-subject control comparisons revealed complexity previously undetected. This study was also the first to investigate and thus establish the relation between client engagement and sudden gains.
