Apathy and Depression as Predictors of Activities of Daily Living Following Stroke and Traumatic Brain Injuries in Adults: A Meta-Analysis

Importance effects on performance in event-based prospective memory tasks

In the present study we manipulated the importance of performing two event-based prospective memory tasks. In Experiment 1, the event-based task was assumed to rely on relatively automatic processes, whereas in Experiment 2 the event-based task was assumed to rely on a more demanding monitoring process. In contrast to the first experiment, the second experiment showed that importance had a positive effect on prospective memory performance. In addition, the occurrence of an importance effect on prospective memory performance seemed to be mainly due to the features of the prospective memory task itself, and not to the characteristics of the ongoing tasks that only influenced the size of the importance effect. The results suggest that importance instructions may improve prospective memory if the prospective task requires the strategic allocation of attentional monitoring resources.

Forgetting of intentions in demanding situations is rapid

Demanding work settings often require the deferral of intended actions. In 3 experiments, participants were to withhold a response until they encountered a task change (which occurred 5, 15, or 40 sec later). To approximate highly demanding settings, the experimenters sometimes divided attention during the delay period. During some of the delays the experimenters interrupted the participants with an additional task (Experiment 1). Demanding conditions as well as interruptions revealed rapid forgetting of intentions at levels that would be considered significant in applied settings. Experiments 2 and 3 showed that this rapid forgetting was not reduced by strategic rehearsal and implementation intention strategies. The results suggest that maintaining intentions over brief delays is not a trivial task for the human cognitive system.     

Problem Anger in Psychotherapy: An Emotion-Focused Perspective on Hate, Rage, and Rejecting Anger

This paper explores applies emotion-focused theory, for the first time, to the emotions of hate, rage, and destructive anger. The general case formulation proposed in this paper is that these emotions are always an elaboration of secondary anger. The body of the paper describes three clinical case formulations. First, problem anger is described in terms of an individual’s self-criticism. Second, we present a form of secondary anger, in which hostility and rage are reactive feelings to avoid more vulnerable (primary) experiences. An unfortunate example of this is has been described as a common underlying process in domestic violence. A alternate manifestation of secondary anger results from the deterioration of what may have initially been adaptive anger; thus, excessive arousal and the loss of meaning or focus that one’s anger embodied also leads to rage or destructive anger. Finally, the experience and expression of hate is described as a primary maladaptive and/or instrumental anger. This appears in-session particularly among those with certain personality disorders. The paper highlights implications for research and practice.     

A sham drug improves a demanding prospective memory task

Every day, people rely on prospective memory--our ability to remember to perform a future action--to carry out myriad tasks. We examined how a sham cognitive enhancing drug might improve people's performance on a prospective memory task. We gave some people (but not others) the sham drug, and asked everyone to perform a high-effort prospective memory task. People who received the sham drug performed better on the prospective memory task. They also took longer to perform their ongoing task, suggesting that they increased their effortful monitoring. These results fit with research showing that suggestions can lead people to increase cognitive effort and increase memory performance.     

The Influence of Psychological Contract Breach on Temporary Workers’ Commitment and Behaviors: A Multiple Agency Perspective

Purpose  

The purpose of this study was to examine the influence of psychological contract breach on the commitment and behaviors of temporary workers engaged in a multiple agency relationship. Specifically, it aimed to measure the influence of contract breach by the employing agency and the client organization on temporary workers’ trust and affective commitment to the respective party, and on their adoption of discretionary behaviors at the client site.     

Planning and on-line control of catching as a function of perceptual-motor constraints

Two experiments were conducted in order to investigate the adaptability and associated strategies of the human perceptuo-motor system to deal with changing constraints. In a catching task, perceptual-motor constraints were internally controlled by coupling movement onset of the catch and the illumination circuit in the lab: upon the first movement of the catcher, all lights went out within 3 ms. The authors studied (a) how much movement time catchers prefer if no visual information is available after movement onset, and (b) how movement execution changes under such temporal constraints. It was hypothesised that, in order to accomplish successful catching behaviour, (1) movement initiation would be postponed in order to allow sufficient information uptake before the lights went out, and (2) an alternative control strategy would have to be mobilised, since on-line control becomes inappropriate when catching in the dark. In the first experiment, the adaptation process to the light-dark paradigm was investigated. In the second experiment, the conclusions from experiment 1 were challenged under varying ball speeds. In order to maintain catching performance, subjects initiated the catch approximately 280 ms before ball-hand contact. Next to changes in temporal structure of the catch and subtle kinematic adaptations, evidence for a change in the control mode emerged: while an on-line control strategy was adopted under normal illumination, catching movements seemed to be executed as planned in advance when catching in the dark. Additionally, perceptual constraints seem to determine the time of movement initiation, rather than motor constraints. These results emphasize the capability of the human perceptuo-motor system to adjust promptly to new task constraints.     

The Read-Recite-Review Study Strategy: Effective and Portable

ABSTRACT— Two experiments with college students investigated the effectiveness of the 3R (read-recite-review) strategy for learning from educational texts. The 3R strategy was compared with rereading and note-taking study strategies using free-recall, multiple-choice, and short-answer inference tests immediately after study and after a 1-week delay. In Experiments 1 and 2, 3R improved immediate and delayed free recall of fact-based passages, relative to the rereading and note-taking strategies. In Experiment 2 , which used longer, more complex passages on engineering topics, performance on multiple-choice and problem-solving items was better in the 3R than in the rereading condition, and was equivalent in the 3R and note-taking conditions, though 3R took less study time than note taking. An inherent advantage of 3R relative to other testing methods for improving learning is that 3R is under the learner's control. These results indicate that it is also an efficacious study technique that capitalizes on the mnemonic potency of retrieval and feedback.     

Effort awareness and sense of volition in schizophrenia

Contemporary experimental research has emphasised the role of centrally generated signals arising from premotor areas in voluntary muscular force perception. It is therefore generally accepted that judgements of force are based on a central sense, known as the sense of effort, rather than on a sense of intra-muscular tension. Interestingly, the concept of effort is also present in the classical philosophy: to the French philosopher Maine de Biran [Maine de Biran (1805). Mémoire sur la décomposition de la pensée (Tome III), Vrin, Paris (1963)], the sense of effort is the fundamental component of self-experience, the landmark of the exercise of the will. In the present review, after a presentation of the nature and neurophysiological bases of effort sensation, we will examine its possible involvement in the neurocognitive process of agency. We will further focus on delusions of alien control in schizophrenic patients. Experimental data suggest that these patients have an abnormal awareness of effort caused by cerebral anomalies in the frontal and parietal lobes.
