Effects of aging and divided attention on episodic feeling-of-knowing accuracy

This research investigated the effect of aging on episodic feeling-of-knowing (FOK) using a divided attention (DA) paradigm in order to examine whether DA in younger adults mimics the effects of aging when decreasing either memory encoding or monitoring processes. To that end, four groups of participants were tested on the FOK task: young adults (control group), young adults under DA at encoding, young adults under DA when making FOK judgments, and older adults. Our results showed that DA at encoding in young adults mimicked the effect of aging on memory performance, and also on FOK magnitude and accuracy, supporting the memory-constraint hypothesis ( Hertzog et al., 2010). However, our results do not completely contradict the monitoring-deficit hypothesis, as DA during FOK judgments also affected FOK accuracy, but to a lesser extent than the aging effect or DA during encoding. We suggest that the age-related FOK deficit may be due to a lower level of deep encoding, leading to difficulty retrieving target-related contextual details enabling accurate prediction of subsequent recognition.     

Effects of attentional load and ageing on word-stem and word-fragment implicit memory tasks

The joint effects of reduced attention and age on repetition priming in implicit memory tests of word-fragment completion (WFC) and word-stem completion (WSC) were investigated. An attention load during the study phase reduced the extent of repetition priming in the WSC condition but not in WFC. This finding provides support for the view that WSC and WFC involve different processes. However, there was no evidence of an age effect on either of these two types of implicit tasks. The data also revealed an overall significant effect of age and reduced attention on explicit cued recall tasks.     

Procedural vs. direct retrieval strategies in arithmetic: A comparison between additive and multiplicative problem solving

The opposition between declarative and procedural knowledge is used to account for the solution by more or less expert and novice arithmeticians of simple additions and multiplications presented either in mixed blocks (Experiments 1 and 3) or unmixed blocks (Experiment 2) in an equation verification task. In the three experiments, presenting the sign (+ vs 2) before the operands had a stronger effect in additions than in multiplications. This priming effect indicates that many participants use a counting procedure for additions that coexists with the declarative knowledge stored in the associative network. In contrast, the small size (and sometimes the absence) of a priming effect for the ''x'' sign, together with the weak effect of size and the frequency of interaction effects, reveals the essentially declarative nature of multiplication solution.     

Effect of distinctive encoding on false recognition,discrimination, and decision criteria in young and elderly adults

In order to examine the effects of distinctive encoding on age-related differences in false memory and decision criteria, we used a standard recognition paradigm and manipulated three encoding conditions: control, general, and distinctive. The results revealed main effects of age and encoding condition on hits and false recognition, and interactions between these variables, with elderly adults benefiting more than young adults from the encoding tasks. In the distinctive encoding condition, the age-related difference on false recognition was eliminated. These findings are discussed in terms of an age-related deficit in self-initiated distinctive processing. Further analyses showed that elderly adults used a more lenient decision criterion than young adults. Distinctive encoding led all subjects to use stringent decision criteria, but did not eliminate age differences.     

Imagery and the processing of visuo-spatial representations: A symposium

Abstract

Four cross-language primed lexical decision experiments were carried out to test models of cross-language priming. The first experiment varied the proportion of related pairs, but this manipulation did not affect the size of the priming effects. In Experiments 2 and 3, the subjects were asked to respond at a specific fast rate. This resulted in significant priming within languages, but priming in the cross-language conditions disappeared. The subjects in Experiment 4 were also asked to respond at a specific fast rate, but the stimuli in this experiment were translation equivalents. Cross-language priming occurred with the translations under the same conditions where it had disappeared with primary associates. These results suggest that cross-language priming between primary associates is due to a post-lexical meaning-integration process which the subjects can detach from the normal reading sequence if it slows their responses in relation to goal response rate.     

Does Dispositional Aggression Feed the Narcissistic Response? The Role of Narcissism and Aggression in the Prediction of Job Attitudes and Counterproductive Work Behaviors

Purpose

The purpose of this study was to extend the personality and work-related outcomes literature by examining: (1) the effects of narcissism on job satisfaction, organizational commitment, and counterproductive work behaviors and (2) the moderating effects of dispositional aggression on the narcissism–counterproductive work behaviors relationship.

Design/Methodology/Approach

Multi-wave data were collected from 381 workers employed in a variety of work settings within the United States.

Findings

Narcissism had consistent main effects on job satisfaction, organizational commitment, and counterproductive work behaviors after controlling for the personality characteristics agreeableness, conscientiousness, neuroticism, and aggression. Aggression moderated the relationship between narcissism and counterproductive work behaviors, such that the positive relationship between narcissism and counterproductive work behaviors was stronger when dispositional aggression was high.

Implications

This study provides greater clarity regarding the role of narcissism within job attitudes and behaviors, shows that dispositional aggression strengthens or amplifies the narcissistic response for counterproductive work behaviors, and provides a platform to further explore narcissism and aggression within the workplace.

Originality/Value

This study found that narcissism consistently predicted unique variance in work-related criteria after the effects of agreeableness, conscientiousness, neuroticism, and aggression were controlled. It also found evidence that aggression moderates the effects of narcissism on counterproductive work behaviors. This study is the first to directly examine these effects.     

Leader Profiles and Their Effectiveness on Employees’ Outcomes

An underlying premise of the transformational–transactional leadership theory is that different forms of leadership can reside simultaneously within the same individual. This fundamental hypothesis has received scarce attention in the empirical literature. The objectives of this study are thus to examine whether leader profiles combining these leadership forms do exist and to evaluate how these profiles are associated with specific employee attitudes and behaviors. Results obtained from two different samples using cluster analyses revealed six different leader profiles (i.e., superleaders, transactors, moderate leaders, distant-visionary, distant-rewarding, and distant-punitive leaders). Our results showed that these types of leaders differ in terms of employees’ perceptions of trust, justice, and commitment, as well as supervisor-rated in-role and contextual performance. Results and implications for research and practice are discussed.     

Development of Cognitive Skills in Children with Motor Coordination Impairments at 12-Month Follow-up

The current study presents a 1-year follow-up investigation of the development of executive functions (i.e., inhibition, updating, and shifting) in children with motor coordination impairments. Cognitive and motor coordination skills of children (N = 94) aged between 5 and 7 years with and without motor coordination impairments were compared. A second focus of the study was on pre-academic skills. The results indicate marked stability of motor coordination impairments and persistent executive functioning deficits in motor-impaired children. Inhibition and shifting performance was consistently lower, compared to the children without motor coordination impairments. Moreover, children with motor coordination impairments showed lower pre-academic skills, facing a substantial disadvantage at the beginning of formal schooling. The combined cognitive and motor problems may be the result of an underlying inhibition deficit or a general automation deficit. Implications for intervention are discussed.     

“If It Helps,I’ll Carry On”: Factors Supporting the Participation of Native and Immigrant Youth in Belgium and Germany

In this article we propose looking into some factors for Civic Participation and the intention to continue to participate among local (Study I) and immigrant (Study II) young people living in Belgium and Germany. In Study I, 1,079 young people (M_age = 19.23, 44.9% males) completed a self-report questionnaire asking about their Civic Participation. Multiple linear regressions reveal (a) evidence of a pool of variables significantly linked to Civic Participation: Institutional Trust, Collective-Efficacy, Parents’ and Peers’ Support, Political Interest, Motivations and (b) that Civic Participation, along with the mediation of the Participation's Efficacy, explains the Intention to Continue to Participate. An explanatory model was constructed on participation and the Intention to Continue to Participate on behalf of the native youth. This model is invariant between the two countries. In Study II, 276 young Turkish immigrants (M_age = 20.80, 49.3% males) recruited in Belgium and Germany filled out the same questionnaire as in Study I. The same analysis was conducted as for Study I, and they provided the same results as the native group, highlighting the invariance of the model between natives and immigrants. Applicative repercussions are discussed.
