    Still committed to the normativity of folk psychology

    , Article Philosophical Explorations ; 2021 ; 13869795 (ISSN) Kazemi, A ; Sharif University of Technology
    Routledge  2021
    In what sense can one claim that intentional explanations are essentially normative, given that people’s actions and thinking are replete with various irrationalities, yet are still pretty well explained by this explanatory framework? This article provides a novel response to this enduring objection. First, following Brandom, it is suggested that, to understand the normativity of intentional states, we should countenance and distinguish between two normative categories of commitment and entitlement, only the former of which is argued to be essential for intentional explanations. Conflating these two normative dimensions is noted to be one of the main sources of the objections leveled against... 

    Unpacking entrepreneurial alertness: How character matters for entrepreneurial thinking

    , Article Journal of Small Business Management ; 2021 ; 00472778 (ISSN) Pirhadi, H ; Soleimanof, S ; Feyzbakhsh, A ; Sharif University of Technology
    Taylor and Francis Ltd  2021
    Over centuries and across cultures, scholars have consistently highlighted the role of character for achieving personal and societal good. Yet we know little about how character matters for entrepreneurship. This study builds upon the theory of character strengths to extend our knowledge about personal antecedents of entrepreneurial thinking. Specifically, we examine how character strengths of valor, industriousness, and critical thinking can affect different dimensions of entrepreneurial alertness: scanning and search, association and connection, and evaluation and judgment. We use two samples of 412 students and 145 entrepreneurs to test the study’s hypotheses. The results shed light on...

    Leading change authentically: how authentic leaders influence follower responses to complex change

    , Article Journal of Leadership and Organizational Studies ; Volume 24, Issue 2 , 2017 , Pages 157-171 ; 15480518 (ISSN) Alavi, S. B ; Gill, C ; Sharif University of Technology
    Organizational change has become complex and challenging, and employee attitudes and beliefs toward change are even more important. This article proposes a theoretical framework on how authentic leadership may influence followers’ change-oriented attitudes, beliefs, and behaviors through follower psychological resources including hope, trust, optimism, self-efficacy, and resilience, which influence readiness for change and change implementation. We maintain that an authentic leader’s behavior can influence his or her followers’ change-oriented behaviors in participation in decision-making processes and change initiatives, organization citizenship behavior, organizational learning processes,...

    Considerations on the Empirical Adequacy of Jung’s Theory of Psychoanalysis

    , M.Sc. Thesis Sharif University of Technology Shirazi, Maral (Author) ; Hosseini Sarvary, Hassan (Supervisor)
    Carl Jung's analytical psychology is a psychoanalytic theory that has been established with the assumption of the existence of a collective and inheritable unconscious containing archetypes. The archetypes are psychic patterns that have evolved throughout human history and are inherited by human infants. Repressing these innate and universal properties can cause psychic problems for humans. Those repressed innate properties could emerge indirectly to keep the mental balance, but this may cause problems due to being out of conscious control of the individual. According to Jung's claim, remembering and accepting these repressed identities and then integrating the conscious and unconscious... 

    On The Foundation of Cognitive Sciences: A Critique of Neurotheology

    , M.Sc. Thesis Sharif University of Technology Solgi, Farshid (Author) ; Hosseini, Hassan (Supervisor)
    One of the tasks of philosophy of science is to study the pre-suppositions involved in the natural sciences, to study the concepts used in scientific researches and theorizing. Hence, neglecting philosophy and even the modality of philosophical views, can have devastating effects on any science, including psychology (if it can be called science). Wittgenstein believed that in psychology we are confronted with experimental methods and conceptual confusion, and that this confusion does not go away with giving the title of young knowledge to the psychology. The emergence and dominance of behaviorism can be attributed to the effects of positivism and the uncomprehensive interpretation of physics...

    Attenuated asymmetry of functional connectivity in schizophrenia: A high-resolution EEG study

    , Article Psychophysiology ; Volume 47, Issue 4 , Jul , 2010 , Pages 706-716 ; 00485772 (ISSN) Jalili, M ; Meuli, R ; Do, K. Q ; Hasler, M ; Crow, T. J ; Knyazeva, M. G ; Sharif University of Technology
    The interhemispheric asymmetries that originate from connectivity-related structuring of the cortex are compromised in schizophrenia (SZ). Under the assumption that such abnormalities affect functional connectivity, we analyzed its correlate - EEG synchronization - in SZ patients and matched controls. We applied multivariate synchronization measures based on Laplacian EEG and tuned to various spatial scales. Compared to the controls who had rightward asymmetry at a local level (EEG power), rightward anterior and leftward posterior asymmetries at an intraregional level (1st and 2nd order S-estimator), and rightward global asymmetry (hemispheric S-estimator), SZ patients showed generally... 

    Optimizing Landing Page by Digital Nudging Model; Case Study: Hair Clinic

    , M.Sc. Thesis Sharif University of Technology Matloubi, Mojtaba (Author) ; Isaai, Mohammad Taghi (Supervisor) ; Najmi, Manouchehr (Supervisor)
    Living in a digital era, more and more of businesses are going online. Sudden outbreak of covid19 pandemic accelerated the expansion of e-commerce and pushed an increasing number of businesses to go online. One of the most important issues in a world of e-commerce, is how to measure the results and improve the outputs. Focusing on the digital marketing, the process is usually called “conversion rate optimization”. While there is an extensive literature on various methods of improvement and optimization, we aim to do so using the notion of digital nudging, which is rather a novel concept. Digital nudging is a model that, by incorporating nudge techniques and cognitive biases, tries to change... 

    The Nature of Folk Psychology and Its Implications for Designing Artificial Agents and Humanoid Robots

    , Ph.D. Dissertation Sharif University of Technology Safdari Sharabiani, Abootaleb (Author) ; Azadegan, Ebrahim (Supervisor)
    How do we enter into empathic relations with inanimate objects (IO)? Do we indirectly infer that they possess mental states, or directly perceive them as mental things? In recent years these questions have been addressed by a number of authors. Some argue in favor of an indirect approach that involves mediatory procedures; others defend a direct approach that postulates no intermediate. In this paper I argue on the side of the latter. I show that Simulation Theory (ST), one of the most elaborated versions of the indirect approach, does not have the capacity to account for our empathy with IO.Investigating ST paves the way for criticizing a special kind of indirect theory, namely Imaginative... 

    The effects of a short-term memory task on postural control of stroke patients

Method: Center of pressure (COP) fluctuations were measured in three levels of postural difficulty (rigid surface with closed and open eyes and foamsurface with closed eyes), aswell as two levels of cognitive difficulty (easy and difficult). COP parameters included mean velocity, standard deviation of velocity in both medial-lateral (M.L) and... 

    Individual differences in nucleus accumbens dopamine receptors predict development of addiction-like behavior: A computational approach

    , Article Neural Computation ; Volume 22, Issue 9 , 2010 , Pages 2334-2368 ; 08997667 (ISSN) Piray, P ; Keramati, M. M ; Dezfouli, A ; Lucas, C ; Mokri, A ; Sharif University of Technology
    Clinical and experimental observations show individual differences in the development of addiction. Increasing evidence supports the hypothesis that dopamine receptor availability in the nucleus accumbens (NAc) predisposes drug reinforcement. Here, modeling striatal-midbrain dopaminergic circuit, we propose a reinforcement learning model for addiction based on the actor-critic model of striatum. Modeling dopamine receptors in the NAc as modulators of learning rate for appetitive-but not aversive-stimuli in the critic-but not the actor-we define vulnerability to addiction as a relatively lower learning rate for the appetitive stimuli, compared to aversive stimuli, in the critic. We...

    According to the Highway Capacity Manual, definitions of level of service for freeways are generally in terms of such service measures as freedom to maneuver, change in free flow speed, and drivers' physical and psychological comfort. These quality measures are inherently uncertain and are highly dependent on user perceptions. However, users' perception of traffic operational conditions has not been explicitly considered in defining LOS categories. This study attempt to evaluate freeways LOS and other quality measures describing LOS, based on user perception. Therefore, twenty 1-minute video clips of a weaving freeway segment were shown to users. For each video clip, users' perceptions of...

    , Article Proceedings - 2010 7th International Conference on Fuzzy Systems and Knowledge Discovery, FSKD 2010, 10 August 2010 through 12 August 2010 ; Volume 1 , August , 2010 , Pages 41-44 ; 9781424459346 (ISBN) Hadavandi, E ; Shavandi, H ; Ghanbari, A ; Sharif University of Technology
    Forecasting stock price time series is very important and challenging in the real world because they are affected by many highly interrelated economic, social, political and even psychological factors, and these factors interact with each other in a very complicated manner. This article presents an approach based on Genetic Fuzzy Systems (GFS) for constructing a stock price forecasting expert system. We use a GFS model with the ability of rule base extraction and data base tuning for next day stock price prediction to extract useful patterns of information with a descriptive rule induction approach. We evaluate capability of the proposed approach by applying it on stock price forecasting...

    Aims Previous reports on the possible effects of Extremely Low Frequency Magnetic Fields (ELF MF) on mood have been paradoxical in different settings while no study has yet been conducted on animal behavior. In addition, it was shown that ELF MF exposure makes an increase in brain nitric oxide level. Therefore, in the current study, we aimed to assess the possible effect(s) of ELF MF exposure on mice Forced Swimming Test (FST) and evaluate the probable role of the increased level of nitric oxide in the observed behavior. Main methods Male adult mice NMRI were recruited to investigate the short term and long term ELF MF exposure (0.5 mT and 50 Hz, single 2 h and 2 weeks 2 h a day). Locomotor...
