Sex trade workers' narratives of sexual violence: a field investigation

A total of 119 sex trade workers were interviewed about sexually violent experiences. Up to three narratives were elicited: a remarkable, positive (control) event (POS), a well-remembered sexual assault (WELL), and a poorly recalled sexual assault (POOR). The results demonstrated that WELL narratives contained more details than POS narratives despite the fact that the respective experiences were older. WELL narratives were also associated with higher intoxication and more rehearsal than POS narratives. POOR narratives were as detailed as POS narratives. WELL narratives were associated with more PTSD symptoms than POOR narratives. No weapon focus effect and no differences in peritraumatic dissociation were observed to explain this difference. This study was the first to demonstrate great within-participants variability of narrative details in accounts of sexual violence. The findings challenge common opinions in the eyewitness literature. Implications for expert testimony and credibility assessment are discussed.

Three-step priming in lexical decision

In two experiments, we investigated mediated two-step priming (e.g., from LION to STRIPES via TIGER) and three-step priming (e.g., from MANE to STRIPES via LION and TIGER). Experiment 1 showed robust two-step priming in the double lexical decision task. In Experiment 2, we tested for three-step priming and investigated the possibility that it is not association strength based on free association, but frequency of co-occurrence, that causes three-step priming. Co-occurrence has been proposed as a measure of familiarity and semantic relatedness. Significant three-step priming was obtained. Lexical co-occurrence could not account for the effect. However, a more global measure of semantic similarity that includes the similarity of the contexts in which concepts occur revealed that the three-step pairs were semantically related. If this global measure provides a proper estimate of the semantic relatedness of our items, then three-step priming is consistent not only with spreading activation models, but also with distributed memory models and the compound cue model.     

Effects of Physical Exercise on Resources Evaluation,Body Self-Concept and Well-Being Among Older Adults

This study addressed the effects of a 14-week moderate physical activity program on resources evaluation, body self-concept and other health-related psychological variables among older adults. In a quasi-experimental design participants were divided into three groups and completed questionnaires twice, before ( t 1) and after ( t 2) the 14-week program. The experimental group participated in a supervised mixed exercise program of moderate intensity. The placebo attention control group took part in a foreign language course. The no intervention control group did not get any intervention/attention at all. The dependent variables were resources evaluation, body self-concept, trait anxiety, and psychosomatic complaints. Using the pretest data as covariates multivariate analyses of covariance revealed significant improvements in body self-concept in the experimental group compared to the control groups. No other significant differences could be detected. Results point to the positive effects of exercise on body self-concept even among older adults.     

Recollection and Familiarity in Aging Individuals with Mild Cognitive Impairment and Alzheimer’s Disease: A Literature Review

Memory impairment is a central cognitive symptom in mild cognitive impairment (MCI) and Alzheimer Disease (AD). Recognition tasks are often used to characterize and define the nature of memory deficits. Dual-process theories posit that familiarity and recollection are independently involved in the recognition of previously encountered material and both contribute to successful recognition. Recent evidence indicates that there is a double dissociation in the neuronal substrates of those two processes. More precisely, it has been suggested that perirhinal and entorhinal areas are selectively involved in familiarity-based recognition, while the hippocampus is associated with recollection. Interestingly, these regions are among the first to be targeted by neurofibrillary tangles, one of AD’s neuropathological hallmarks. Impairment in recognition performance can occur in the very early stages of AD, such as MCI. To define the nature of recognition impairment in these clinical populations, we reviewed the current literature on familiarity and recollection performance in individuals with MCI and AD. Together with clinical features, methodological factors are taken into consideration in the interpretation of findings.     

How the ventral pathway got lost: and what its recovery might mean

Textbooks dealing with the anatomical representation of language in the human brain display two language-related zones, Broca's area and Wernicke's area, connected by a single dorsal fiber tract, the arcuate fascicle. This classical model is incomplete. Modern imaging techniques have identified a second long association tract between the temporal and prefrontal language zones, taking a ventral course along the extreme capsule. This newly identified ventral tract connects brain regions needed for language comprehension, while the well-known arcuate fascicle is used for "sensorimotor mapping" during speech production. More than 130 years ago, Carl Wernicke already described a ventral connection for language, almost identical to the present results, but during scientific debate in the following decades either its function or its existence were rejected. This article tells the story of how this knowledge was lost and how the ventral connection, and in consequence the dual system, fits into current hypotheses and how language relates to other systems.     

Structure and limited capacity in verbal working memory: a study with event-related potentials

In order to test recent claims about the structure of verbal working memory, two ERP experiments with Dutch speaking participants were carried out. We compared the ERP effects of syntactic and semantic mid-sentence anomalies in subject and object relative sentences. In Experiment 1, the participants made acceptability judgments, while in Experiment 2 they read for comprehension. Syntactic anomalies concerned subject-verb disagreement, while semantic anomalies were related to implausible events (e.g., *The cat that fled from the mice ran through the room). Semantic anomalies did not elicit an N400 effect. The semantic as well as syntactic anomalies elicited P600 effects, with similar centro-parietal scalp distributions. For both kinds of anomaly, the P600 effects were modulated by syntactic complexity: they were either relatively small (Experiment 1) or absent (Experiment 2) in object relative sentences. Taken together, our results suggest that: (a) verbal working memory is a limited capacity system; (b) it is not subdivided into an interpretative and a post-interpretative component (); (c) the P600 can reflect the presence of a semantic bias in syntactically unambiguous sentences; (d) the P600 is related to language monitoring: its function is to check upon the veridicality of an unexpected (linguistic) event; (e) if such a check is made, there is no integration of the event and hence no N400 effect.
