Fluency Task

The study examined individual differences in code-switching to determine the relationship between code-switching frequency and performance in verbal and non-verbal task switching. Seventy-eight Cantonese–English bilinguals completed a semi-structured conversation to quantify natural code-switching, a verbal fluency task requiring language switching, and two non-verbal switching tasks. Participants who engaged in more conversational code-switching showed smaller costs in verbal task switching than those who switched languages less frequently. Participants performed similarly to bilinguals in previous studies on non-verbal switching tasks, but in this case performance was not linked to the degree of conversational code switching. The difference in the influence of code-switching for verbal and non-verbal executive control tasks indicates a dissociation between domains for the mechanism of task switching.

There is a general agreement that speaking requires attention at least for conceptual and lexical processes of utterance production. However, conflicting results have been obtained with dual-task paradigms using either repetition tasks or more generally tasks involving limited loading of lexical selection. This study aimed to investigate whether post-lexical processes recruit attentional resources. We used a new dual-task paradigm in a set of experiments where a continuous verbal production task involved either high or low demand on lexical selection processes. Experiment 1 evaluates lexical and post-lexical processes with a semantic verbal fluency task, whereas experiments 2 and 3 focus on post-lexical processes with a non-propositional speech task. In each experiment, two types of non-verbal secondary tasks were used: processing speed (simple manual reaction times) or inhibition (Go/No-go). In Experiment 1, a dual-task cost was observed on the semantic verbal fluency task and each non-verbal task. In Experiment 2, a dual-task cost appeared on the non-verbal tasks but not on the speech task. The same paradigm was used with older adults (Experiment 3), as increased effort in post-lexical processes has been associated with ageing. For older adults, a dual-task cost was also observed on the non-propositional verbal task when speech was produced with the inhibition non-verbal task. The results suggest an attentional cost on post-lexical processes and strategic effects in the resolution of the dual-task.

The Relationship

The purpose of this research is to determine the organizational support for professionalism that has never been done before. The research approach is to conceptualize the structure of the relationship of variables from a study. Verification research is to test the hypothesis through data collection in the field using two methods, namely descriptive survey and explanatory survey. The use of both methods aims to analyze the causality relationship between research variables in accordance with the hypothesis quantitatively. There is significant influence between the variables of organizational support to professional variables. However, different results are found on the influence of organizational support variables on OCB and performance that have no significant effect. There is also an indirect influence between organizational support variables on OCB and performance through intermediary intervening professionalism variables. The difference between this research and the previous research are the use of constructs and the measurement in the unit of analysis being used.

Purpose The purpose of this paper is to discuss the different approaches to the corporate reputation construct, in order to identify a comprehensive definition that can be used for measurement purposes, gaps identified by previous literature identified. Design/methodology/approach This is a theoretical essay. The authors analyzed studies that involve the relationship between corporate reputation and organizational performance, and the attributes of national and international corporate reputation ratings. Findings The authors identified a more comprehensive definition for the reputation construct, and indicated courses for the construct’s measurement, by considering: the judgment by the stakeholders (internal, suppliers, clients and the financial market); periodical evaluations under different organizational perspectives; attention to theoretical assumptions, among other aspects. Research limitations/implications The study is a theoretical paper that presents that the research field has many definitions that cannot be used interchangeably. It indicated how the reputation construct should be operationalized for measurement purposes. This study presented a reflection on the relationship between corporate reputation and performance, showing that it is not a settled topic in the academy. Practical implications The study advances the understanding of the reputation construct measurement, considering the adopted definition and the discussion of the attributes of the main ratings on corporate reputation. The adoption of a measurement method that takes into account the definition used in this study and the features of the methodologies discussed will improve the corporate reputation assessment. Social implications Literature indicates that a good corporate reputation can affect organizational performance and the inverse relationship is also true. As a social implication, it is extremely relevant to improve the understanding the definition and measurement methods of this construct. Originality/value This study discusses one of the most important intangible resources for organizations, contributing to the understanding of the difference between the market value and the book value of public companies. Besides it should be considered that there is one lack of a definition directly related to the measurement of the reputation construct in the literature, a gap in which this study contributes.

Abstract Objective This poster will focus on findings pertaining to the relationship between bilingualism and Attention Deficit/Hyperactivity Disorder (ADHD), a gap that currently exists in cultural neuropsychology. This poster will introduce the literature regarding bilingualism and the development of individuals’ executive functioning throughout their lifespan. Bilingual individuals often have enhanced executive functioning. This review will provide a foundation for the present study. Then, we will compare racial and ethnic differences in ADHD diagnosis and treatment. ADHD diagnoses tend to be higher for White children than for Hispanics raised in a non-English household. These findings suggest that bilingualism may affect the diagnosis and the expression of ADHD. Participants and Method This poster will consider the acquisition of executive control skills and language. Since ADHD and language develop before adolescence, this poster will focus on individuals between the ages of 3 and 12. This will allow us to better understand how language acquisition and the factors that surround language affect the expression of ADHD. Results The poster will present results from the literature review to better understand the results of bilingualism on ADHD. Bilinguals tend to outperform monolinguals in tasks related to reasoning and problem solving. However, bilinguals tend to struggle in tasks related to vocabulary retrieval. This is key because individuals with ADHD tend to perform worse on tasks related to executive functioning. The poster will display different methods used in past research in order to expand future implications. Conclusions ADHD appears to interrupt some skills that bilingual individuals possess. This interference may affect ADHD symptom expression and performance on neuropsychological testing. This may lead to misdiagnoses and a resulting lag in the provision of effective treatments for bilingual children. Thus, this poster will propose alternatives and implications for practice.

The Relationship

Previous studies of bilingual adults have suggested that bilinguals’ experience with code-switching (CS) contributes to superior executive function (EF) abilities. We tested a highly bilingual developing population in Singapore, a multilingual country where CS occurs pervasively. We obtained CS and EF measures from 43 English–Chinese 8-year-old children (27 females, M = 100 months). We measured spontaneous CS with a novel task and EF in terms of task-switching (Semantic Fluency) and inhibitory control (Stroop task in both languages). Contrary to previous work, CS performance did not significantly predict EF performance in either case. Rather, bilingual language proficiency, i.e., degree of bilingualism (as measured by direct proficiency tests and parents’ estimates of daily language use and exposure of both languages) influenced EF performance. Accordingly, the relationship between CS and EF may be more indirect and non-necessary than previously assumed.

AbstractAn increasing number of people, students in particular, seek substances that improve their cognitive functioning. The most popular group of pharmacological cognitive enhancers (PCEs) are stimulants. Available studies suggest a small beneficial effect of methylphenidate and amphetamine on memory, executive functions, and processing speed. However small, this effect can make the difference between success and failure. In recent years, research has focused on the additional beneficial effect on the emotional state, increased motivation, and placebo-induced cognitive enhancement. This paper briefly reviews the latest and most important research on the relationship between popular stimulants and cognitive enhancement. One cannot understand this relationship without understanding the Yerkes-Dodson law, which explains the relationship between the degree of arousal and performance. It suggests that the effect of stimulants is a dose-dependent continuum. This law has repeatedly been confirmed by studies in which an optimal level of psychoactivation for cognitive enhancement was obtained with low stimulant doses, whereas exceeding the effective dose resulted in cognitive deficits, psychomotor agitation, and addiction. A separate section has been devoted to modafinil, an increasingly popular stimulant that differs from the rest in neurochemical profile and behavioural effects.

Purpose This study aims to explore the factors moderating possibly indirect relationships between gender diversity and its effect on bank performance. The causality of this relationship remains unclear. Design/methodology/approach The sample consists of all banks (n = 27) operating in Serbia. Findings The gender diversity-performance relationship is indirect. The gender diversity of executive boards positively impacts bank performance, over a threshold level. This is observed only in banks where gender diversity is extended to more than one level of executive authority. Research limitations/implications Gender diversity should be fostered, particularly in small and competitive markets. The gender diversity-performance link is based on gender-related social interactions, which are interdependent and should not be taken into account as isolated factors. Originality/value To the knowledge, this is the first study to provide insight into indirect, gender related, moderatory interactions effecting gender diversity – performance link, in banking.

China has set stringent fuel consumption rate (FCR) targets to address the serious environmental and energy security problems caused by vehicles. Estimating the technological progress and tradeoffs between FCR and vehicle attributes is important for assessing the viability of meeting future targets. In this paper, we explored the relationship between vehicle FCR and other attributes using a regression model with data from 2009–2016. We also quantified the difference in the tradeoff between local and joint venture brands. The result showed that from 2009 to 2016, if power and curb mass were held constant, 2.3% and 2.9% annual technological progress should have been achieved for local and joint venture brands, respectively. The effectiveness of fuel-efficient technologies for joint venture brands is generally better than that of local brands. Impacts of other attributes on FCR were also assessed. The joint venture brands made more technological progress with FCR improvement than that of local brands. Even if 100% of technological progress (assume the technological progress in the future were the same as that of 2009–2016) investment were used to improve actual FCR after 2016, it would be difficult to meet 2020 target. Accelerating the adoption of fuel-efficient technologies, and controlling weight and performance, are both needed to achieve the 2020 and 2025 targets.

The Impact

Abstract Bilingualism is reported to re-structure executive control networks, but it remains unknown which aspects of the bilingual experience cause this modulation. This study explores the impact of three code-switching types on executive functions: (1) alternation, (2) insertion, and (3) dense code-switching or congruent lexicalisation. Current models hypothesise that different code-switching types challenge different aspects of the executive system because they vary in the extent and scope of language separation. Two groups of German-English bilinguals differing in dense code-switching frequency participated in a flanker task under conditions varying in degree of trial-mixing and resulting demands to conflict-monitoring. Bilinguals engaging in more dense code-switching showed inhibitory advantages in the condition requiring most conflict-monitoring. Moreover, dense code-switching frequency correlated positively with monitoring skills. This suggests that dense code-switching is a key experience shaping bilinguals’ executive functioning and highlights the importance of controlling for participants’ code-switching habits in bilingualism research.
