A limit on retrieval-induced forgetting

Retrieving some members of a memory set impairs later recall of semantically related but not unrelated members (M. C. Anderson, R. A. Bjork, & E. L. Bjork, 1994; M. C. Anderson & B. A. Spellman, 1995). The authors investigated whether this retrieval-induced forgetting effect would generalize to testing procedures other than category-cued recall. Although the authors demonstrated a retrieval-induced forgetting effect using a category-cued recall task, they failed to show retrieval-induced forgetting on several different memory tests that used item-specific cues, including a category-plus-stem-cued recall test, a category-plus-fragment-cued recall test, a fragment-cued recall test, and a fragment completion task.     

Self-focusing situations and depression

The author examined the situations in which people turn their attention to the self and investigated differences between depressed and nondepressed persons in self-focusing situations. He developed a Self-Focusing Situation List containing 58 items and administered the list to 436 Japanese undergraduates. He also administered a depression scale to part of the sample (n = 365). A factor analysis extracted 6 factors, and cluster analyses of these 6 factors scores yielded 5 clusters. The participants who preferred self-focusing when alone and avoided self-focusing after positive events (Cluster 5) scored higher on the depression scale than did the participants in Clusters 1, 2, 3, and 4.     

Is self-positive information more appealing than money? Individual differences in positivity bias according to depressive symptoms

The self-positivity bias, which is inherent to healthy people, is known to be blunted in depression. The lack of positive or excessive negative self-reference is considered to be a potential mechanism underlying depressive rumination. However, the motivational factors that drive people to approach and avoid emotional self-related materials are still unclear. Therefore, we measured intrinsic motivation that is associated with emotional self-references by using a reward-based decision-making task (pay-per-view paradigm). Forty-nine undergraduates completed two tasks in which they were asked to choose between negative vs. positive references (Task 1) and self vs. other references (Task 2) for variable monetary rewards. Participants with lower levels of depressive symptoms showed a self-positivity bias, sacrificing rewards for the opportunity to engage in positive self-reference, whereas those with higher levels of depressive symptoms had no specific preference for either negative or positive self-reference (Task 1). However, all participants sacrificed monetary rewards for the opportunity for self-reference versus other reference, regardless of the symptom level or the primed valence (Task 2). Together, these findings suggest that depressive cognition could be characterised by the lack of intrinsic motivation for positive self-reference, which is attributable to the biased valence selection, but not to self–other preferences.     

The Impact of Religiosity and Individual Prayer Activities on Advanced Cancer Patients’ Health: Is There Any Difference in Function of Whether or Not Receiving Palliative Anti-neoplastic Therapy?

Consecutive patients (n = 221) presenting for initial consultation at a palliative care outpatient clinic were prospectively interviewed and then followed until death. Individual prayer activity (IPA) and global religion scores were associated with quality of life, symptoms, inflammatory markers, and survival. Analyses were adjusted for whether patients were still receiving anti-neoplastic therapies (ANTs) or not. Higher religion scores were associated with lower levels of inflammation in advanced cancer patients still undergoing ANTs. Additionally, higher IPA was an independent good prognostic factor in patients on active ANTs. Further studies are necessary to confirm these findings and to investigate possible biological mechanisms involved.     

The role of verbal labels in the judgment of orientation and location

In an earlier study it was found that judgments of right-left orientations and locations were more difficult than judgments of up-down only when spatial words were used in the tasks. Experiments are reported in which pictures of many objects were presented to eliminate the possibility that subjects in previous studies had used strategies specific to single-stimulus tasks. In experiment 1, right-left orientations were judged more slowly than up-down orientations both when the spatial words were used and when arbitrary letters replaced the spatial words. In experiment 2, judgments of the right-left locations of pictures took longer than judgments of their up-down locations only when spatial words were used in the task; the right-left difficulty was eliminated when arbitrary letters replaced the words. The differential effect of words and letters in location judgments seems to be due to the different coding strategies adopted by subjects under the two conditions. It is concluded that a right-left difficulty does not depend on the use of spatial terms: word and letter conditions yield different results only when the task permits different judgments to be made under the two conditions.     

Work Engagement in Japan: Validation of the Japanese Version of the Utrecht Work Engagement Scale

The purpose of this study was to validate the Japanese version of the Utrecht Work Engagement Scale (UWES‐J). Employees from three independent samples completed the questionnaire (total N= 2,334). Confirmatory factor analyses using the multiple‐group method revealed that, instead of the original three‐factor model, a one‐factor model that assumes that all engagement items load on one single factor fitted the data. Moreover, the one‐factor structure was invariant across all three samples. Internal consistency of the scale was sufficiently high (α= .92) and the test–retest reliability with an interval of two months was .66. A series of second‐order confirmatory factor analyses to examine construct validity confirmed the hypothesised model, indicating that work engagement was positively related to job satisfaction whereas it was negatively related to strain and burnout. However, as in previous studies, professional efficacy, a component of burnout, loaded on the engagement factor. These results, in general, suggest the reliability (internal consistency and stability), factorial invariance, and construct validity of the UWES‐J in three independent samples. Cette étude avait pour objectif de valider la version japonaise de l’Echelle d’Implication au Travail d’Utrecht (UWES‐J). 2,334 salariés provenant de trois échantillons indépendants ont rempli le questionnaire. Une analyse factorielle confirmatoire faisant appel à la méthode des groupes multiples a montré que le modèle originel en trois facteurs devait laisser la place à un modèle unifactoriel puisque tous les items d’implication étaient saturés sur un unique facteur qui rendait compte à lui seul des données. En outre, la structure monofactorielle restait identique à elle‐même sur les trois échantillons. La consistance interne de l’échelle était suffisamment élevée (α= .92) et la fidélité test‐retest après une période de deux mois était de .66. Une série d’analyses factorielles confirmatoires de second ordre destinées àétudier la validité de construction ont confirmé le modèle hypothétique, indiquant que l’implication dans le travail était en corrélation positive avec la satisfaction professionnelle tandis qu’elle était en relation négative avec la tension nerveuse et le burnout. Comme dans des travaux antérieurs, l’efficacité professionnelle, une composante du burnout, était saturée dans le facteur d’implication. Ces résultats, vont dans le sens de la fidélité (consistance interne et stabilité), de la solidité factorielle et de la validité de construction de l’UWES‐J dans ces trois échantillons indépendants.     

Numbsense of shape,texture, and objects after left parietal infarction: A case report

Numbsense is a phenomenon, wherein patients can correctly respond to somatosensory stimuli at a higher rate than expected by chance, but cannot perceive the same stimuli consciously. Previously, numbsense has been reported in tactile localization of stimuli on the patient’s own body. Here, we describe a patient with numbsense that involved touched objects. The patient could not recognize the majority of somatosensory stimuli after left parietal infarction, but could correctly select shape, texture, and object stimuli more frequently than expected by chance.
