The role of executive processes in prospective memory tasks

Prospective remembering refers to remembering and acting on behavioural intentions. Three experiments tested the hypothesis that prospective remembering requires the availability of executive processes. It was expected that this is more important when intentions are stated in categorical terms. Type of instruction (specific versus categorical), typicality of the cue in relation to the category specified, and executive load were manipulated. Results showed a general benefit of specific instructions. Furthermore, with categorical instructions, performance was better with typical cues. Although the data suggested that executive processes are responsible for the processing of cues, the load manipulation had no significant effect on the prospective memory measure. Thus, no evidence was found for the hypothesis that prospective remembering requires the availability of executive processes. It is argued that it is a matter of strategic choice whether executive processes are deployed: One does not need to monitor for cues but can choose to rely on bottom‐up processes. Monitoring may be sufficient, but not necessary for successful prospective remembering.     

Executive control in the Simon task: A dual-task examination of response priming and its suppression

Executive control processes are supposed to regulate behaviour and to resolve conflicts in information processing. Recently, Stürmer and colleagues (Stürmer et al., 2002; Stürmer & Leuthold, 2003) reported electrophysiological findings in a Simon task that indicated control over a location-based processing route that mediates response priming. Importantly, when a response conflict occurred on a given trial, a suppression of response priming on the immediately following trial was demonstrated. The present study examines boundary conditions of such control in the Simon paradigm by comparing single-task with dual-task performance. In four experiments a second task, alternating trial-by-trial with the Simon task, was systematically manipulated in its control demands. Whereas reaction time (RT) analysis of single-task conditions revealed the absence of location-based response priming in the Simon task, such priming reappeared when the second task required an overt response. In contrast, working memory load as such did not touch the Simon effect. Therefore, not the response conflict itself but capacity-limited response monitoring processes seem to be critical for executive control in the Simon task and the suppression of response priming.     

Exploring self-defining memories in schizophrenia

Previous studies have shown that patients with schizophrenia are impaired in recalling specific events from their personal past. However, the relationship between autobiographical memory impairments and disturbance of the sense of identity in schizophrenia has not been investigated in detail. In this study the authors investigated schizophrenic patients’ ability to recall self-defining memories; that is, memories that play an important role in building and maintaining the self-concept. Results showed that patients recalled as many specific self-defining memories as healthy participants. However, patients with schizophrenia exhibited an abnormal reminiscence bump and reported different types of thematic content (i.e., they recalled less memories about past achievements and more memories regarding hospitalisation and stigmatisation of illness). Furthermore, the findings suggest that impairments in extracting meaning from personal memories could represent a core disturbance of autobiographical memory in patients with schizophrenia.     

Suppression-induced forgetting on a free-association test

The repeated suppression of thoughts in response to cues for their expression leads to forgetting on a subsequent test of cued recall (Anderson & Green, 2001). We extended this effect by using homograph cues and presenting them for free association following suppression practice. Cue–target pairs were first learned under integrating imagery instructions; then in the think/no-think phase students practised suppressing thoughts connected to some homograph cues, with or without the assistance of thought substitutes that changed their meaning. Below-baseline forgetting on the subsequent free-association test was found in the production of suppressed targets. Following aided suppression this effect was also obtained in the production of other responses denoting the target-related meaning of the homograph cues. Discussion emphasises the ecological value of the test; rarely do people deliberately attempt recall of unwanted thoughts.     

Impact of Motivational Climates on Claimed Self-Handicapping Strategies: Illustration in Tropical Environment

The purpose of the present study was to quantitatively and qualitatively examine whether claimed self-handicapping is increased in a performance motivational climate (PMC) compared with a mastery motivational climate (MMC) within a strictly controlled tropical environment. Participants completed measures of self-handicapping using open-ended questions before a physical test. The analyses revealed that (a) participants who engage in self-handicapping strategy were more numerous, (b) the number of self-handicap reported self-handicap score were greater, and (c) participants who engage in self-handicapping strategy reported more impediments in the PMC as compared with MMC. Information about the nature of self-handicapping claims is also provided.     

Patients’ illness schemata of hypertension: The role of beliefs for the choice of treatment

It has long been believed that adult somatic complaints are associated with early family dysfunction. Yet, few studies have examined this hypothesis in community samples, where medically unexplained symptom complaints are estimated to be very common. Given the potential population-wide impact of subthreshold symptom complaints as well as questions about the extent to which findings with patient populations generalize to broader samples of community adults, the present study examines the influence of distal family factors on current adult somatic complaints relative to demographic and other psychosocial predictors. Results based on multiple linear regression analysis indicated that, after controlling for the other variables, family-of-origin functioning did not predict adult somatic complaints. However, self-reported symptoms of current depressed mood and low internal locus of control were significantly linked to somatic complaints (p?=0.001). These results lend support to questions about the generalizability of findings based on psychiatric groups to broader community samples, highlight the robust relationship between contemporaneous attributions of lower internal control, depressed mood, and somatic complaints, and suggest that early family environment may not be the most important focus of attention for health professionals providing care to adults in the community.     

Call for Papers: National Conference in Sales Management

This article combines a constructivist grounded theory approach with a focus on structuration theory to propose a new mental model for understanding motivation in the context of solving complex problems in contemporary business-to-business (B2B) settings. This study uses the interpretative tradition of qualitative research to conduct in-depth interviews of 24 B2B sales professionals and subsequently analyze their lived experiences. Findings indicate that intrinsic motivation stems attitudinally from a need to foster an identity of helping customers, introducing a concept called “interpersonal identification” with customers. That identity motivates the development of more cognitively intense sales proposals using a more holistic proposal development process – referred to herein as “systems-savvy selling.” While interpersonal relationships have long been components of B2B relationships, this study challenges laypeople’s stereotypes of salespeople who use interpersonal relationships to improve business outcomes. Instead, systems-savvy selling helps salespeople build interpersonal relationships and use business outcomes as feedback to strengthen interpersonal relationships and their identification with customers. Unexpectedly, it also finds that dual-role sales managers, who have roles both in selling and managing, confront a paradox of self versus others when managing systems-savvy selling processes. By sampling within an industry in which the research team benefits from significant expertise, the constructivist grounded theory approach relying on semistructured, in-depth interviews used herein leverages the research team’s expertise while controlling for industry-level effects.     

Mentalization in children and mothers in the context of trauma: An initial study of the validity of the Child Reflective Functioning Scale

This study examined the validity of the Child Reflective Functioning Scale (CRFS: Ensink, Target, & Oandason, 2013, Child reflective functioning scale scoring manual: for application to the Child Attachment Interview. London, UK: Anna Freud Centre – University College London), a measure designed to assess reflective functioning (RF) or mentalization during middle childhood. Participants were 94 mother–child dyads divided into two subgroups; 46 dyads where children had histories of intrafamilial (n = 22 dyads) or extrafamilial (n = 24 dyads) sexual abuse, and a community control group composed of 48 mother–child dyads. RF of children and their mothers was assessed using videotaped and transcribed data gathered using the Child Attachment Interview and the Parent Development Interview (PDI: Slade, Aber, Bresi, Berger, & Kaplan, 2004, The parent development interview‐Revised. New York, NY: The City University of New York). The findings indicate that the CRFS proved reliable, with excellent intraclass correlation coefficients for general RF, as well as RF regarding self and others. Significant differences in RF were found between sexually abused children and the control group, and also between children who had experienced intrafamilial and extrafamilial sexual abuse. This provides support for the discriminant validity of the CRFS. Furthermore, maternal RF was associated with child RF. Both abuse and maternal RF made significant contributions to predicting children's RF regarding themselves, but child sexual abuse was the only variable that made a significant contribution to explaining variance in children's RF regarding others.     

Reward speeds up and increases consistency of visual selective attention: a lifespan comparison

Children and older adults often show less favorable reward-based learning and decision making, relative to younger adults. It is unknown, however, whether reward-based processes that influence relatively early perceptual and attentional processes show similar lifespan differences. In this study, we investigated whether stimulus–reward associations affect selective visual attention differently across the human lifespan. Children, adolescents, younger adults, and older adults performed a visual search task in which the target colors were associated with either high or low monetary rewards. We discovered that high reward value speeded up response times across all four age groups, indicating that reward modulates attentional selection across the lifespan. This speed-up in response time was largest in younger adults, relative to the other three age groups. Furthermore, only younger adults benefited from high reward value in increasing response consistency (i.e., reduction of trial-by-trial reaction time variability). Our findings suggest that reward-based modulations of relatively early and implicit perceptual and attentional processes are operative across the lifespan, and the effects appear to be greater in adulthood. The age-specific effect of reward on reducing intraindividual response variability in younger adults likely reflects mechanisms underlying the development and aging of reward processing, such as lifespan age differences in the efficacy of dopaminergic modulation. Overall, the present results indicate that reward shapes visual perception across different age groups by biasing attention to motivationally salient events.
