Researchers have recently begun to question the specificity and reliability of conflict adaptation effects, also known as sequential congruency effects (SCEs), a highly cited effect in cognitive psychology. Some have even used the lack of reliability across tasks (e.g., Flanker, and Stroop) to argue against models of cognitive control that have dominated the field for decades. The present study tested the possibility that domain-general processes across tasks might appear on more sensitive mouse-tracking metrics rather than overall reaction times. The relationship between SCE effects on the Stroop and Flanker tasks were examined for the first time using a mouse-tracking paradigm. Three main findings emerged: (1) Robust SCEs were observed for both the Stroop and Flanker tasks at the group level, (2) Within-task split-half reliabilities for the SCE across dependent variables were weak at best and non-existent in many cases, and (3) SCEs for the Flanker and Stroop tasks did not correlate with each other for overall reaction times, but did show significant correlations between tasks on more dynamic measures that captured processes before response execution. These findings contribute to the literature by highlighting how mouse-tracking may be a fruitful avenue by which future studies can examine the specificity and reliability of conflict adaptation and tease apart different theoretical models producing the effects.

Purpose The purpose of this study was to examine (a) explicit and implicit verbal response inhibition in preschool children who do stutter (CWS) and do not stutter (CWNS) and (b) the relationship between response inhibition and language skills. Method Participants were 41 CWS and 41 CWNS between the ages of 3;1 and 6;1 (years;months). Explicit verbal response inhibition was measured using a computerized version of the grass–snow task (Carlson & Moses, 2001), and implicit verbal response inhibition was measured using the baa–meow task. Main dependent variables were reaction time and accuracy. Results The CWS were significantly less accurate than the CWNS on the implicit task, but not the explicit task. The CWS also exhibited slower reaction times than the CWNS on both tasks. Between-group differences in performance could not be attributed to working memory demands. Overall, children's performance on the inhibition tasks corresponded with parents' perceptions of their children's inhibition skills in daily life. Conclusions CWS are less effective and efficient than CWNS in suppressing a dominant response while executing a conflicting response in the verbal domain.

This study aims to explore the relationship between social anxiety and Theory of Mind (ToM) ability. Findings are evaluated in the context of theoretical models (Clark & Wells, 1995; Heimberg et al., 2010), to aid improvement of the understanding of social anxiety disorder (SAD). Two hypotheses are proposed: (1) social anxiety will negatively associate with self-report and objective measures of ToM ability; (2) objective and self-report measures of ToM will be positively associated. Literature assessing the relationship between social anxiety and ToM has not produced consistent results and has exclusively focused on ToM decoding and reasoning ability. This study is the first to explore the relationship between social anxiety, cognitive and affective ToM ability, and self-reported ToM ability. A correlational study was conducted (36 participants), comparing Social Interaction Anxiety Scale scores (SIAS; Mattick & Clarke, 1998) for social anxiety levels; Interpersonal Reactivity Index (IRI) perspective-taking subscale scores for self-reported ToM ability (Davis, 1980); error rate (in millimeters) on the Paper and Pencil Sandbox Task (Coburn, Bernstein, & Begeer, 2015) for cognitive ToM ability; and reaction times on the Yoni Task (Shamay-Tsoory & Aharon-Peretz, 2007) for cognitive and affective ToM ability. Contrary to expectations, no significant relationships were found between any of the measures. The results prompt re-thinking regarding the mechanisms of SAD and offer insight into the complexity of the relationship between social anxiety and ToM ability. However, the implications can only be inferred within the context of the study limitations, these are discussed alongside recommendations for future research.

The Relationship

Abstract. This study aimed to assess whether brain potentials have significant influences on the relationship between aerobic fitness and cognition. Behavioral and electroencephalographic (EEG) data was collected from 48 young adults when performing a Posner task. Higher aerobic fitness is related to faster reaction times (RTs) along with greater P3 amplitude and shorter P3 latency in the valid trials, after controlling for age and body mass index. Moreover, RTs were selectively related to P3 amplitude rather than P3 latency. Specifically, the bootstrap-based mediation model indicates that P3 amplitude mediates the relationship between fitness level and attention performance. Possible explanations regarding the relationships among aerobic fitness, cognitive performance, and brain potentials are discussed.

Elementary Cognitive Tasks

Effects of four retest-practice sessions separated by 2 h intervals on the relationship between general intelligence and four reaction time tasks (two memory tests: Sternberg's memory scanning, Posner's letter comparison; and two attention tests: continuous attention, attention switching) were examined in a sample of 83 male participants. Reaction times on all tasks were shortened significantly. The effects were most pronounced with respect to the Posner paradigm and smallest with respect to the Sternberg paradigm. The relationship to general intelligence changed after practice for two reaction time tasks. It increased to significance for continuous attention and decreased for the Posner paradigm. These results indicate that the relationship between psychometric intelligence and elementary cognitive tasks depends on the ability of skill acquisition. In the search for the cognitive roots of intelligence the concept of learning seems to be of importance.

Abstract. Previous research suggests that parenting style influences the development of the needs for achievement, power, and affiliation. The present study investigated the relationship between parenting style and another important motive disposition – the need for autonomy – in a sample of Singapore university students ( N = 97, 69% female), using a cross-sectional and retrospective design. It was predicted that an authoritative perceived parenting style would relate positively to the implicit need for autonomy ( nAut), the explicit need for autonomy ( sanAut), and the congruence between these two motive dispositions. Authoritative maternal parenting was found to positively associate with sanAut, while maternal parenting was not found to associate with nAut, or with nAut/ sanAut congruence. Paternal parenting was not associated with any of the dependent variables.

The Relationship

This note examines the relationship between affirmative action (AA) program perceptions and women’s self-ascribed capacity and desire to become leaders. We propose that women who believe that their organization implements a program of preferential selection toward women will experience negative psychological effects leading to lowered self-expectations for leadership, but that this effect will be moderated by their justice perceptions of AA programs. We test this proposition empirically for the first time with a Latin American female sample. Among Brazilian women managers, desire but not self-ascribed capacity to lead was reduced when they believed an AA policy was in place. Both desire’s and capacity’s relationships with belief in an AA policy were moderated by justice perceptions.

Впервые в мире создана популяция зубров на территории 60 градусов северной широты. В новых климатических условиях разведения и сохранения зубров определены и проанализированы факторы существования вида на севере Европейской части РФ. Выявлены признаки, динамика численности, которые являются составной частью системы, предназначенной для управления биоразнообразием. Интродукция, являясь процессом введения в экосистему нехарактерных для нее видов, может усиливать изменения биоценозов как положительно, так и отрицательно. Насколько быстро и успешно проходит процесс адаптации заселенного вида, и усматривается его влияние на окружающую среду зависит дальнейшее существование зубров и в целом биоразнообразия. В статье обсуждаются вопросы взаимоотношения зубров с другими видами копытных и хозяйственной деятельностью человека, а также дальнейшим использованием зубров в сельскохозяйственном производстве. Пластичность зубров, выявление изменений и их анализ при вселении видов в новые условия обитания необходимы не только для определения развития или деградации биоценозов и в целом экосистемы, но и прогноза социально-экономических последствий интродукции как одного из методов сохранения редких и исчезающих видов фауны.For the first time in the world, a bison population has been created in an area of 60 degrees north latitude. In the new climatic conditions of breeding and preservation of bison, the factors of the species existence in the north of the European part of the Russian Federation are identified and analyzed. The signs, dynamics of abundance, which are an integral part of the system designed to manage biodiversity are identified, since the preservation of biological diversity on the planet is one of the main problems of our time. Introduction, being the process of introducing non-typical species into an ecosystem, can enhance changes in biocenoses, both positively and negatively. The question posing sounds especially when it comes to such a large hoofed animal as the European bison. How quickly and successfully the process of adaptation of the universe takes place and its environmental impact is seen depends on the continued existence of bison and biodiversity in general. The article discusses the relationship of bison with other types of ungulates and human activities, as well as the further use of bison in agricultural production. How these issues will be resolved positively depends on the future of these animals. Thus, the plasticity of bison, the identification of changes and their analysis, with the introduction of species into new habitat conditions is necessary not only to determine the development or degradation of biocenoses and the ecosystem as a whole, but also to predict the socio-economic consequences due to the introduction as one of the methods of preserving rare and endangered species of fauna.

Small and medium enterprises (SMEs) are considered as foundation stones of economic development and growth of any economy (Centobelli, Cerchione, & Esposito, 2019). Performance of SMEs is of fundamental significance for all developed as well as developing nations. Similarly, Pakistan is no exception to aforementioned fact. The economic development and growth of Pakistan depend on the performance of SMEs to a great extent. Like, most countries in the world, SMEs comprise more than 90% of total business entities in Pakistan (Degong et al., 2018; Waqas & Nawaz, 2019) and leather industry in one that is attracted by the researchers of present study. Constraints in the growth of leather industry of Pakistan include, lack of skilled human capital, rising cost of production, lack of modern-day knowledge about new products and processes, low profitability and lack of capability to penetrate into international markets, lack of market research, access to finance, intensive competitive rivalry (Khalique et al., 2011; Daily Times, 2016, Awan et al., 2019). Few studies have revealed mixed findings regarding the relationship between knowledge management and firm performance and there is abundance of literature that demonstrates the presence of significant and positive relationship between Market Orientation and Firm performance (Slater & Narver , 1995; Baker & Sinkula, 2009; Udriyah, Tham, & Azam, 2019). On the other hand, some studies have argued that there is no direct and significant relationship between Market Orientation and Firm Performance (Polat & Mutlu, 2012; Shehu & Mahmood, 2014). Moreover, keeping in view the mixed and inconclusive findings regarding the relationship between cause and effect variables, it is appropriate to introduce moderating variables that can significantly influence the relationship between independent and dependent variables as recommended by Baron and Kenny (1986). Access to Finance and Competitive Environment can be served as prospective moderators which are quite appropriately related to proposed variables of the study (Prajogo & Oke, 2016; Rogo et al., 2016; Jaworski & Kohli, 1993) which are quite appropriately related to selected variables of the study. Thus, the research problem expressed that "Access to finance and competitive environment can potentially moderates and affect the relationship between independent and dependent variables. Hence, based on the past literature and aforementioned discussion, the present study intended to examine the moderating effects of Access to Finance and Competitive Environment on the Relationship between Human Capital, Knowledge Management, Market Orientation and SMEs Performance in Leather Industry of Pakistan".

Current estimates of obesity costs ignore the impact of future weight loss and gain, and may either over or underestimate economic consequences of weight loss. In light of this, I construct static and dynamic measures of medical costs associated with body mass index (BMI), to be balanced against the cost of one-time interventions. This study finds that ignoring the implications of weight loss and gain over time overstates the medical-cost savings of such interventions by an order of magnitude. When the relationship between spending and age is allowed to vary, weight-loss attempts appear to be cost-effective starting and ending with middle age. Some interventions recently proven to decrease weight may also be cost-effective.
