What are confabulators' memories made of? A study of subjective and objective measures of recollection in confabulation.
No full textConfabulating patients claim to remember events that had not actually happened, suggesting a vivid subjective experience of false memories. The present study was aimed at examining the nature of subjective experience of retrieval in confabulators and its relation to the objective ability to recollect qualitative aspects of the original episode. In Experiment 1, 5 confabulators, 7 non-confabulating patients, and 12 control subjects studied words under shallow and deep encoding conditions and underwent a Remember (R)/Know (K) recognition task [Tulving, E. (1985). Memory and consciousness. Canadian Psychology, 26, 1-12]. For recognized words, they additionally indicated two qualitative features of the encoding context. Whereas subjective (i.e. R responses) and objective (i.e. source) measures of recollection were associated in normal controls and non-confabulating patients, they were dissociated in confabulators. In Experiment 2, participants explained the content of their R responses. We found that confabulators' recollections mainly included autobiographical information related to test items, but not to the study encounter. We conclude that remembering states in confabulators may be linked to a deficit in inhibiting irrelevant memories triggered by test items during retrieval attempts

Age differences in the contribution of recollection and familiarity to false-memory formation: a new paradigm to examine developmental reversals
No full textUsing a new method for studying the development of false-memory formation, we examined developmental differences in the rates at which 6-, 7-, 9-, 10-, and 18-year-olds made two types of memory errors: backward causal-inference errors (i.e. falsely remembering having viewed the non-viewed cause of a previously viewed effect), and gap-filling errors (i.e. falsely remembering having viewed a script-consistent event that was not actually witnessed). Previous research suggests that backward causal- inference errors are supported by recollection, whereas gap-filling errors are supported by familiarity.We hypothesized that age differences in these errors would parallel the developmental trajectories of these processes. As predicted, age-related increases in backward causal-inference errors were observed, while gap-filling errors were age-invariant, suggesting that recollection-based memory distortions increase with age while familiarity-based memory distortions are relatively stable from middle childhood through adulthood
A mechanistic model for re-entrainment in wave plate demisters
No full textAmong the separation devices used to remove minute droplets of liquid from a gas stream, wave plate mist eliminators, which separate the two phases by inertial impaction, are usually adopted in many applications.
Re-entrainment limits the gas-liquid separator performance because it causes a sharp decrease in separation efficiency and therefore gas velocity cannot exceed a certain value.
This work presents new experimental data for the critical gas velocity at which re-entrainment occurs in industrial wave plate mist eliminators operated at atmospheric conditions with horizontal flow. The results show how the critical gas velocity is influenced by physical properties and flow rate of the liquid and by separator geometry. This paper also presents a new model for predicting re-entrainment based on the calculation of the liquid load on each plate between two consecutive bends of the separator. To this scope, an efficiency model was used to evaluate liquid flow over each plate and a mechanistic model was developed to compute the re-entrainment from the trickles which are formed on the plates by the coalescence of liquid droplets that impinge on the blades of the wave plate mist eliminator. The model developed takes into account the parameters which influence re-entrainment according to experimental data, it could be used to predict the critical velocity for different wave plate mist eliminators and therefore it is useful to design new ones
