Hand Grip and Load Force Coordination of the Ipsilesional Hand of Chronic Stroke Individuals

Object manipulation depends on a refined control of grip force (GF) and load force (LF). After a brain injury, the GF control is altered in the paretic hand but what happens with the non-paretic hand is still unclear. In this study, we compared the GF control and GF–LF coordination of the non-paretic hand of 10 stroke individuals who suffered right brain damage (RBD) and 10 who suffered left brain damage (LBD), with 20 healthy individuals during lifting and oscillation task, using an instrumented object. GF was recorded with a force transducer, and LF was estimated from the object weight and acceleration. Overall, the ipsilesional hand of stroke individuals, independent of the lesion side, presented similar GF control and GF–LF coordination. However, LBD individuals took longer to start lifting the object, which may be due to the need of more time to obtain somatosensory information from the contact with the object. The findings indicate that stroke individuals preserve their ability to control and coordinate GF and LF when using their ipsilesional hand for object manipulation and the left hemisphere may play an essential role in the processing of somatosensory information needed for the GF control.     

On angry leaders and agreeable followers. How leaders' emotions and followers' personalities shape motivation and team performance

Do followers perform better when their leader expresses anger or when their leader expresses happiness? We propose that this depends on the follower's level of agreeableness. Anger is associated with hostility and conflict-states that are at odds with agreeable individuals' goals. Happiness facilitates affiliation and positive relations-states that are in line with agreeable individuals' goals. Accordingly, the two studies we conducted showed that agreeableness moderates the effects of a leader's emotional displays. In a scenario study, participants with lower levels of agreeableness responded more favorably to an angry leader, whereas participants with higher levels of agreeableness responded more favorably to a neutral leader. In an experiment involving four-person teams, teams composed of participants with lower average levels of agreeableness performed better when their leader expressed anger, whereas teams composed of participants with higher average levels of agreeableness performed better when their leader expressed happiness. Team performance was mediated by experienced workload, which was highest among agreeable followers with an angry leader. Besides having important practical implications, the findings shed new light on the fundamental question of how emotional expressions regulate social behavior.     

Bilingualism changes children's beliefs about what is innate

Young children engage in essentialist reasoning about natural kinds, believing that many traits are innately determined. This study investigated whether personal experience with second language acquisition could alter children's essentialist biases. In a switched‐at‐birth paradigm, 5‐ and 6‐year‐old monolingual and simultaneous bilingual children expected that a baby's native language, an animal's vocalizations, and an animal's physical traits would match those of a birth rather than of an adoptive parent. We predicted that sequential bilingual children, who had been exposed to a new language after age 3, would show greater understanding that languages are learned. Surprisingly, sequential bilinguals showed reduced essentialist beliefs about all traits: they were significantly more likely than other children to believe that human language, animal vocalizations, and animal physical traits would be learned through experience rather than innately endowed. These findings suggest that bilingualism in the preschool years can profoundly change children's essentialist biases.     

Cross-Cultural Competence: The Role of Emotion Regulation Ability and Optimism

Cross-cultural competence (3C) is critical for military personnel to understand and perform effectively in complex cultural environments and to interact with individuals from other cultures. The knowledge, skills, and abilities that make up 3C can result in clearer communication, build trust, and strengthen relationships in cross-cultural social contexts ( Selmeski, 2009 Selmeski, B. (February, 2009). Military Cross-cultural competence: Core concepts and individual development. Proceedings from the 7th Biennial Equal Opportunity, Diversity, and Culture Research Symposium. Patrick Air Force Base, FL. [Google Scholar]). This research investigated the role of emotional regulation and optimism in the development of 3C in military personnel. Results demonstrate that the ability to regulate emotions is positively related to 3C, both directly and through its effect on optimism.     

The risky side of inspirational appeals in personal selling: when do customers infer ulterior salesperson motives?

In personal selling, the inspirational appeal (IA) is a widely promoted tactic that aims at stimulating customers' values and ideals, thereby evoking emotions and arousing their enthusiasm for a product. However, whether IAs in fact improve or undermine salespeople's success in sales talks remains controversial. Therefore, this study examines consequences and key contingencies of IAs in customer–salesperson interactions in a retailing context, using multisource data from several retailing industries for three quantitative studies, comprising a total sample of 590 customer and 174 salesperson responses. Drawing on the Multiple Inferences Model (MIM), the authors show that an IA is likely to drive the customer's inference that the salesperson holds ulterior motives. IAs seem to be particularly detrimental for salespeople with a lack of customer orientation. Beyond expanding research on influence tactics and the ambivalent role of IAs in retailing interactions, these findings can guide practitioners about when to refrain from using an IA.     

Racial reckoning,resistance, and the revolution: A call to community psychology to move forward

This article introduces a special issue of the American Journal of Community Psychology that features racial reckoning, resistance and the revolution in the context of a syndemic, the historical subjugation of communities of Color (COC) to racial hierarchies and the coronavirus (COVID-19). More specifically, this special issue underscores the need for community psychology and other allied disciplines to address this syndemic facing COC. The special issue delivers on the stories of the lived experiences from researchers and community members as it relates to COVID-19 and COC. Twelve articles are illuminated to challenge the field to create social change.     

The Relationship Between Employees’ Objective Internal and External Pay Standing and Their Job Performance: A Within-Person Analysis

Purpose

Researchers have paid little attention to the relationship between employees’ objective internal and external pay standing and their job performance. Moreover, few studies have considered that employees’ objective pay standing is dynamic; that is, it changes over time. In this study, we analyze the relationship between changes in employees’ objective internal and external pay standing and their job performance.

Design/Methodology/Approach

We test the hypotheses using data for players in the National Basketball Association over a period of 12 seasons (n = 4830).

Findings

Decreases in employees’ objective internal and external pay standing are negatively related to their task performance. Furthermore, decreases in employees’ objective internal pay standing, but not in their external pay standing, are negatively related to their contextual performance.

Implications

Analyzing the relationship between changes in employees’ objective internal and external pay standing and their job performance adds to our understanding of the individual-level consequences of pay dispersion.

Originality/Value

This is one of the first studies to analyze the relationship between employees’ objective internal and external pay standing and their job performance. Moreover, this is one of the first studies that considers that employees’ objective internal and external pay standing changes, for example, because the external and internal labor markets change. The study contributes to research on employee compensation and salary, and to research on pay disparities.

     

Writing as a meaningful activity

Writing processes have been studied extensively from the cognitive point of view, but little attention has been given to the affective aspects of this activity. In fact, writing experience seems to be relevant to a person not only because it is a complex cognitive activity, but also because it often has an affective characterization. The aim of the present study was to investigate writing as a meaningful activity, that is, to analyze the way in which pupils of different grade levels construe this activity. The study was divided into two phases: (a) interviews with pupils in order to select relevant elements (i.e., writing situations and contexts) and (b) subjects' elicitation of constructs and evaluation of elements. From the qualitative and quantitative analyses of the grids, a developmental trend emerged. Whereas the younger subjects frequently elicited constructs related to the affective dimension of writing, as age increased, the cognitive dimension became more evident.     

Infant development of configural object processing in visual and visual-haptic contexts

Infants’ visual processing of objects is characterised by a developmental trend from a predominantly analytical to a configural processing mode. In two studies with 6- and 8-month-old infants, we sought to replicate this finding in a purely visual condition (inspecting objects), and to examine how far redundant visual-haptic information present in a visual-haptic condition influences the processing mode. Infants were familiarized with two objects differing in three dimensions (texture, size and shape). At test, infants were presented with a familiar object, a switch object consisting of a recombination of familiar dimensions, and a novel object, and looking times were measured. Results indicate a transition from analytical processing at 6 months to configural processing at 8 months in the visual condition. In the visual-haptic condition, both age-groups displayed configural processing. Thus, redundant visual-haptic information seems to enhance object processing.     

The Early Presentation of Dementia in People with Down Syndrome: a Systematic Review of Longitudinal Studies

Adults with Down syndrome (DS) are at a very high risk of developing early onset Alzheimer’s disease (AD) due to trisomy of chromosome 21. AD is preceded by a prolonged prodromal “pre-clinical” phase presenting with clinical features that do not fulfil the diagnostic criteria for AD. It is important to clinically characterise this prodromal stage to help early detection of the disease as neuropathology of AD is almost universal by the fifth decade in DS. There is a lack of knowledge of the trajectory of decline associated with the onset of dementia in this population and early signs may be overlooked or misdiagnosed, negatively affecting the quality of life of those affected and the use of early pharmacological or psychosocial interventions. The objective of this systematic review is to evaluate the published literature on longitudinal data in order to identify the cognitive and behavioural changes occurring during the prodromal and early stages of AD in this population. Fifteen peer-reviewed articles met the inclusion criteria, including a total number of 831 participants, with the duration between baseline and follow up varying from 1 year to 47 years. Results suggest that, compared to the general population for which short-term (episodic) memory loss is the most common indicator associated with the onset of AD, in people with DS, executive dysfunction and Behavioural and Psychological Symptoms of Dementia (BPSD) are commonly observed during pre-clinical and early stages and may precede memory loss. The review highlights the importance of using a broad spectrum of assessments in the context of heterogeneity of symptoms. Theoretical and practical implications are discussed, as well as the need for further research.
