Delayed recall of fear extinction in rats with lesions of ventral medial prefrontal cortex

Extinction of auditory fear conditioning is thought to form a new memory. We previously found that rats with vmPFC lesions could extinguish fear to the tone within a session, but showed no recall of extinction 24 h later. One interpretation is that the vmPFC is the sole storage site of extinction memory. However, it is also possible that lesioned rats were unable to retrieve extinction memory stored in other structures. To determine if a latent extinction memory could be retrieved with additional training, we repeated the experiment but added an additional 5 d of extinction reminder trials. Replicating our previous findings, vmPFC-lesioned rats extinguished normally on day 1, but showed no recall of extinction on day 2. Over the next 5 d, however, lesioned rats showed significant savings in their rate of re-extinction. Thus, the vmPFC is not the only site where extinction memory is stored. Nevertheless, lesioned rats receiving only two extinction trials per day required twice as many days to initiate extinction as controls. Although recall of extinction is possible without the vmPFC, it is significantly delayed. We suggest that the vmPFC accelerates extinction by permitting access to recently learned extinction trials, thereby maximizing behavioral flexibility.     

Effect of the paideia seminar on the comprehension of poetry and reading anxiety

This article reports the results of an experimental study on the relative effectiveness of the Paideia Seminar in improving the comprehension of poetry and decreasing reading anxiety. The participants (n = 50) were English as a foreign language (EFL) ninth grade learners enrolled in classrooms at a public school in Lebanon. The study employed a pre-test – post-test control group design whereby two intact classes were randomly assigned to control and experimental conditions. The results indicated that the use of Paideia Seminar was more effective than regular reading instruction in improving the reading comprehension achievement of the experimental group participants and in decreasing reading anxiety.

Pedagogical implications and suggestions for further research are discussed.     

Ethical leadership and organizational citizenship behaviours: the moderating role of organizational identification

This study examines whether the relationship between ethical leadership and organizational citizenship behaviours (OCBs) is contingent on organizational identification. Drawing on substitutes for leadership theory, the study proposes that the relationship between ethical leadership and OCBs will be attenuated when employees strongly identify with their organization. Using a sample of Egyptian banking sector employees, this proposition was tested with hierarchal linear modelling (HLM). The results revealed that the positive relationship between ethical leadership and OCBs was stronger for those lower in organizational identification than for those higher in identification. Overall, the findings of the study shed new light on the conditions through which ethical leadership enhances OCBs.     

Goals in Argumentation: A Proposal for the Analysis and Evaluation of Public Political Arguments

In this paper, I review and compare major literature on goals in argumentation scholarship, aiming to answer the question of how to take the different goals of arguers into account when analysing and evaluating public political arguments. On the basis of the review, I suggest to differentiate between the different goals along two important distinctions: first, distinguish between goals which are intrinsic to argumentation and goals which are extrinsic to it and second distinguish between goals of the act of arguing and goals of argumentative interactions. Furthermore, I propose to analyse public political arguments as multi-purposive activity types and reconstruct the argumentative exchanges as a series of simultaneous discussions. This enables us to examine public political arguments from a perspective in which the intrinsic goals of argumentation are in principle instrumental for the achievement of the socio-political purposes of argumentation, and consequently, it makes our assessment of the argumentative quality of the argument also indicative of the quality of the socio-political processes to which the arguments contribute.     

The Development and Validation of the Rational and Intuitive Decision Styles Scale

Decision styles reflect the typical manner by which individuals make decisions. The purpose of this research was to develop and validate a decision style scale that addresses conceptual and psychometric problems with current measures. The resulting 10-item scale captures a broad range of the rational and intuitive styles construct domain. Results from 5 independent samples provide initial support for the dimensionality and reliability of the new scale, as demonstrated by a clear factor structure and high internal consistency. In addition, our results show evidence of convergent and discriminant validity through expected patterns of correlations across decision-making individual differences and the International Personality Item Pool (IPIP) Big Five traits. Research domains that would benefit from incorporating the concept of decision styles are discussed.     

COVID-19 Help-Seeking Behaviors: Application of the Theory of Planned Behavior

The novel coronavirus disease (COVID-19) is highly contagious. More than 247 million cases have been confirmed by the end of October 2021. Seeking help earlier may slow the spread of COVID-19 because it may help in early detection of infected cases, and it facilitate tracing those who were with close contact with infected cases. The purpose of this study is to identify participants’ intentions toward COVID-19 seeking help and the factors affecting their decision. This is a cross-sectional study. An online survey using Google Forms was used for data collection. Hierarchical multiple regression analysis was used to explain intentions to seek help for COVID-19. The concepts included in the Theory of Planned Behavior and COVID-19 knowledge were used as predictors. The sample included 780 participants, with an average age of 28.60±9.86 years old. Most of the sample were female (67.4%) and having a bachelor’s degree (72.7%). Participants showed high level of knowledge regarding COVID-19, 73% of the sample had a total knowledge score equal to or higher than 85%. Also, participants had high positive attitudes and high intentions to seek help for COVID-19. The four predictors: Attitudes towards COVID-19, subjective norm, perceived behavioral control, and COVID-19 knowledge significantly explained intentions to seek help. Participants had high intentions to seek help for COVID-19, which was related to having positive attitudes toward seeking help, high social approval, high perceived controllability, and high COVID-19 knowledge levels. Regular awareness campaigns during early stages of pandemics should be performed to improve attitudes and knowledge level, which may improve prevention measures, and promote help seeking behaviors. Consequently, this may facilitate early detection of cases, and slow the spread of pandemics.     

Cognitive Diversity and Consensus in Group Decision Making: The Role of Inputs, Processes, and Outcomes

This study contributes to the new and growing body of research on shared cognition by examining how individuals entering a group decision-making context with different perspectives of the issues to be discussed arrive at cognitive consensus. Cognitive consensus refers to similarity among group members regarding how key matters are conceptualized and was operationalized as shared assumptions underlying decision issues in the present research. Utilizing 37 student groups participating in a multi-issue decision-making exercise, the study investigated antecedents and correlates of cognitive consensus. Results revealed that unanimity decision rule groups achieved more cognitive consensus than majority rule groups. In addition, group members inquiring concerning the reasons underlying others' decision preferences, accepting others' viewpoints as legitimate, and incorporating others' perspectives into their own interpretations of the issues was positively related to arriving at a greater degree of cognitive consensus. Cognitive consensus also positively influenced expectations regarding decision implementation and satisfaction.
