The role of metacognition in prospective memory: Anticipated task demands influence attention allocation strategies

The present study investigates how individuals distribute their attentional resources between a prospective memory task and an ongoing task. Therefore, metacognitive expectations about the attentional demands of the prospective-memory task were manipulated while the factual demands were held constant. In Experiments 1a and 1b, we found attentional costs from a prospective-memory task with low factual demands to be significantly reduced when information about the low to-be-expected demands were provided, while prospective-memory performance remained largely unaffected. In Experiment 2, attentional monitoring in a more demanding prospective-memory task also varied with information about the to-be-expected demands (high vs. low) and again there were no equivalent changes in prospective-memory performance. These findings suggest that attention–allocation strategies of prospective memory rely on metacognitive expectations about prospective-memory task demands. Furthermore, the results suggest that attentional monitoring is only functional for prospective memory to the extent to which anticipated task demands reflect objective task demands.     

Bound context features are integrated at encoding

In the present research, we tested the predictions of different accounts of context binding in "remember" judgements. Context binding, defined as the stochastically dependent retrieval of two different context features, has previously been suggested to be due to mechanisms operating at retrieval either by cueing among context features (Meiser & Br?der, 2002) or by cueing between item and context features (Starns & Hicks, 2008). These accounts, however, do not make specific assumptions regarding the underlying memory representation supporting context binding. By contrast, here we propose that a binding process at encoding integrates item and context information into a coherent memory representation. Varying the presentation of the context features during encoding either with both context features presented simultaneously or with features spread over two encoding episodes, data from two experiments corroborate the notion that binding is produced at encoding. This result suggests that a binding process integrating the context features at encoding is necessary for stochastically dependent retrieval of context features.     

Constructing preference from experience: the endowment effect reflected in external information search

People often attach a higher value to an object when they own it (i.e., as seller) compared with when they do not own it (i.e., as buyer)--a phenomenon known as the endowment effect. According to recent cognitive process accounts of the endowment effect, the effect is due to differences between sellers and buyers in information search. Whereas previous investigations have focused on search order and internal search processes (i.e., in memory), we used a sampling paradigm to examine differences in search termination in external search. We asked participants to indicate selling and buying prices for monetary lotteries in a within-subject design. In an experience condition, participants had to learn about the possible outcomes and probabilities of the lotteries by experiential sampling. As hypothesized, sellers tended to terminate search after sampling high outcomes, whereas buyers tended to terminate search after sampling low outcomes. These differences in stopping behavior translated into samples of the lotteries that were differentially distorted for sellers and buyers; the amount of the distortion was predictive of the resulting size of the endowment effect. In addition, for sellers search was more extended when high outcomes were rare compared with when low outcomes were rare. Our results add to the increasing evidence that the endowment effect is due, in part, to differences in predecisional information search.     

Brands on the brain: Do consumers use declarative information or experienced emotions to evaluate brands?

An fMRI study was conducted with unfamiliar and familiar (strong and weak) brands to assess linguistic encoding and retrieval processes, and the use of declarative and experiential information, in brand evaluations. As expected, activations in brain areas associated with linguistic encoding were higher for unfamiliar brands, but activations in brain areas associated with information retrieval were higher for strong brands. Interestingly, weak brands were engaged simultaneously in both processes. Most importantly, activations of the pallidum, associated with positive emotions, for strong brands and activations of the insula, associated with negative emotions, for weak and unfamiliar brands suggested that consumers use experienced emotions rather than declarative information to evaluate brands. As a result, brand experiences should be considered a key driver of brand equity in addition to brand awareness and cognitive associations.     

Curry-Howard Terms for Linear Logic

In this paper we 1. provide a natural deduction system for full first-order linear logic, 2. introduce Curry-Howard-style terms for this version of linear logic, 3. extend the notion of substitution of Curry-Howard terms for term variables, 4. define the reduction rules for the Curry-Howard terms and 5. outline a proof of the strong normalization for the full system of linear logic using a development of Girard's candidates for reducibility, thereby providing an alternative to Girard's proof using proof-nets.     

Accessing singular antecedents in conjoined phrases

Two experiments examined processing of singular pronouns when the antecedent (e.g., Mary) was a noun phrase (NP) in a conjoined phrase (e.g., Mary and John). Whole-sentence reading times showed an increase in processing time associated with splitting the conjoined phrase to access a single NP antecedent. The increase in processing occurred both when the antecedent was in the subject position and when it was in a nonsubject position. The source of the disruption was further investigated using eyetracking methods. Summing over regions of the text, the magnitude of the processing cost incurred by having to split a conjoined NP was closely comparable when there was and when there was not a gender-appropriate distracting potential antecedent. When there was no such potential antecedent, the increase in processing time occurred immediately in the pronoun region when eye movements were measured. In contrast, when there was a second discourse entity that matched the gender and number of the pronoun (but was not a plausible antecedent for the pronoun), eyetracking measures suggested that the processing difficulty was delayed until additional information was read that forced the antecedent to be one of the conjoined NPs. The results are interpreted in terms of Sanford and Garrod’s (1981) scenario-based model of text comprehension.     

Cue self-relevance affects autobiographical memory specificity in individuals with a history of major depression

Previously depressed and never-depressed individuals identified personal characteristics (self-guides) defining their ideal, ought, and feared selves. One week later they completed the autobiographical memory test (AMT). For each participant the number of AMT cues that reflected self-guide content was determined to produce an index of AMT cue self-relevance. Individuals who had never been depressed showed no significant relationship between cue self-relevance and specificity. In contrast, in previously depressed participants there was a highly significant negative correlation between cue self-relevance and specificity--the greater the number of AMT cues that reflected self-guide content, the fewer specific memories participants recalled. It is suggested that in individuals with a history of depression, cues reflecting self-guide content are more likely to prompt a shift to processing of information within the long-term self (Conway, Singer, & Tagini, 2004), increasing the likelihood that self-related semantic information will be provided in response to cues on the autobiographical memory test.     

Neue Felder in der Operationalisierten Psychodynamischen Diagnostik

After the operationalized psychodynamic diagnostics (OPD) system became well established in clinical as well as research contexts, especially in German speaking countries, the OPD task force now focuses on issues, such as modules and new manuals which are related to various clinical contexts. In this article new modules and manuals are presented and discussed in summarized form: the modules for addiction disorders and for forensic patients, the new OPD-2 manual for children and adolescents, an OPD-based manual for formulating initial assessment reports for insurance companies as well as a conceptualization for an operationalized psychodynamic therapy (OPT).
