Prediction accuracy of text recall: Ease, effort and familiarity

Prediction accuracy of text recall was studied in two experiments. Text characteristics (i.e., consistency and distinctiveness) were manipulated in Experiment 1, and familiarity with the reading-task in Experiment 2. The results were also analyzed and discussed in terms of easy processing (Experiment 1), and in terms of increased and more active processing (Experiment 2). Text characteristics did not affect prediction accuracy. However, being familiar with the reading-task led to good and long-lasting prediction accuracy. Thus, subjects reading a school-book text, instructed to learn the contents of it demonstrated reliable memory awareness, both for immediate recall and for delay of one week. It was also suggested that increased processing demands and active reading enhances prediction accuracy.     

Sociolinguistic inference and intercultural coorientation.

We present a model that examines the effects of cultural differences on coorientation (the ability of communicators to accurately encode and interpret the referential and relational meanings of messages). Intercultural coorientation is made problematic by the absence of certain shared communication system knowledge, which in same‐culture interactions is used in the dynamic sociolinguistic negotiation of relational rights and obligations. We propose that the process of sociolinguistic negotiation of meanings relies fundamentally on probabilistic inference and have constructed a model based on Bayes' theorem. The model predicts the effects of the communication situation, communicator stereotypes and prejudice, and some other‐culture speaker errors on conclusions the receiver draws about the message. Using the model, we distinguish between the ethnocentric error of interpreting a communication in terms of one's own culture and the error of not seeing the communication as diagnostic. Among our predictions are: (a) the less diagnostic the communication, the more impact cultural stereotypes will have on attributions; (b) although evidence of sociolinguistic incompetence sometimes causes misunderstanding, it sometimes prevents misunderstanding; (c) multiple consistent features make intentions clearer than would a single cue, but multiple features violating co‐occurrence norms often lead to the attribution of incompetence.     

The tail-elicited tail withdrawal reflex of Aplysia is mediated centrally at tail sensory-motor synapses and exhibits sensitization across multiple temporal domains

The defensive withdrawal reflexes of Aplysia californica have provided powerful behavioral systems for studying the cellular and molecular basis of memory formation. Among these reflexes the tail-elicited tail withdrawal reflex (T-TWR) has been especially useful. In vitro studies examining the monosynaptic circuit for the T-TWR, the tail sensory-motor (SN-MN) synapses, have identified the induction requirements and molecular basis of different temporal phases of synaptic facilitation that underlie sensitization in this system. They have also permitted more recent studies elucidating the role of synaptic and nuclear signaling during synaptic facilitation. Here we report the development of a novel, compartmentalized semi-intact T-TWR preparation that allows examination of the unique contributions of processing in the SN somatic compartment (the pleural ganglion) and the SN-MN synaptic compartment (the pedal ganglion) during the induction of sensitization. Using this preparation we find that the T-TWR is mediated entirely by central connections in the synaptic compartment. Moreover, the reflex is stably expressed for at least 24 h, and can be modified by tail shocks that induce sensitization across multiple temporal domains, as well as direct application of the modulatory neurotransmitter serotonin. This preparation now provides an experimentally powerful system in which to directly examine the unique and combined roles of synaptic and nuclear signaling in different temporal domains of memory formation.

The emotion account of blame

For a long time the dominant view on the nature of blame was that to blame someone is to have an emotion toward her, such as anger, resentment or indignation in the case of blaming someone else and guilt in the case of self-blame. Even though this view is still widely held, it has recently come under heavy attack. The aim of this paper is to elaborate the idea that to blame is to have an emotion and to defend the resulting emotion account of blame.     

Personality and health habits

Abstract

Four hundred and fifty-five males and 523 females from a community sample participated in a study on the relationship between seven health practices (sleeping; breakfasting; snacking; being at good weight; smoking; alcohol consumption and physical activity) and seven personality factors (Neuroticism; Social Inadequacy; Rigidity; Hostility; Self-sufficiency; Dominance and Self-esteem).

It was found that the seven health habits did not constitute a homogeneous operationalization of a construct “positive lifestyle.” The intercorrelations between the different health practices were typically low. The results of MANOVAs and subsequent ANOVAs revealed small, but statistically significant differences between subjects reporting positive and those reporting poor health habits. The failure to find significant interactions with sex indicated that the results for males and females were generally similar. Neuroticism and hostility discriminated best between the groups with poor or good health behaviors. This held for sleeping, exercising, breakfasting daily and smoking. In addition, sporting people scored lower on social inadequacy and higher on self-esteem. Further, individuals who do not have a daily breakfast were more self-sufficient. Snacking individuals were generally less rigid and less dominant, but more hostile. In conclusion, most negative health habits were found to be associated with personality attributes which are intimately related to symptom reporting (neuroticism, hostility). Given the generally weak associations, it is concluded that, in order to obtain a more complete picture of the individual's psychosocial risk profile, lifestyle data should be collected together with information on the person's stress and his or her coping qualities.     

Information processing in patients with first episode major depression

Hammar, Å., Kildal, A. B. & Schmid, M. (2012). Information processing in patients with first episode major depression. Scandinavian Journal of Psychology 53, 445–449. Few studies have investigated cognitive functioning in a group of patients experiencing a first episode of depression. The aim of this study was to investigate how patients diagnosed with a first episode of depression perform in effortful and non‐effortful information processing compared to healthy controls. An experimental paradigm based on a visual search test was applied. Thirty‐one patients and thirty‐one healthy controls were included in the study. All patients experienced a severe level of symptom load at the time of testing. Results showed no significant differences between groups under any of the conditions. Findings in the present study indicate that patients with a first episode of depression perform equally to healthy controls in tasks requiring visual attention in both effortful and non‐effortful information processing.
