The Effects of Physiological Stress on Learning Instructional Materials
(Editura Univ Oradea, 2022) Tuncol, Aleyna Su; Cengil, Betul Beyza; Aydin, Oyku; Kaynak, Hande; Ozcelik, Erol
Psychophysiological studies have shown that stress can both enhance and impair learning. However, there is not enough research on the effects of stress on learning ecologically valid materials. Considering this need, the goal of the current study is to examine the effects of physiological stress on learning instructional materials. Thirty-eight healthy participants held their hands in either ice-cold water (cold pressor stress group) or warm water (control group) for three minutes after studying the instructional material. Learning was assessed by recall and recognition tests given on the following day. The results showed that physiological stress impaired recall but did not affect recognition, suggesting that extreme stress levels had a detrimental effect on learning tests that rely on self-initiated cues.
Losing the Life: a Review on Autobiographical Memory in Alzheimer's Disease
(Istanbul Univ, Fac Letters, dept Psychology, 2021) Aydin, Oyku; Cengil, Betul Beyza; Kaynak, Hande
Alzheimer's disease (AD), the most common type of dementia among older adults, is a progressive and neurodegenerative brain disease. AD is characterized by progressive memory impairments, but not other types of dementia. Autobiographical memory (AM) is defined as episodes recollected from individuals' life, and it is one of the memory systems impaired in AD. One consequence of AM decline in AD is difficulties in the retrieval of recent AMs rather than past ones. AM contains both episodic and semantic components, and it is crucial for self-concept. The aim of the present study is to review the current understanding of AM in people with AD. In the introduction part of the review, AD and its cognitive correlates are presented in detail, with how AM performance is important for the self. In the second part of the review, AM deteriorations in patients with AD are discussed. Factors, such as emotion and olfaction, affecting AM are mentioned along with the neural substrates. In this regard, the effect of the emotional dimension (e.g., valence) on the formation and retrieval of AMs is discussed and how AM is studied with olfactory stimuli is presented, respectively. Studies on the link between AM and emotion have shown that there is a positive shift of AM in AD, indicating that patients with AD remember their AMs more positively. In addition, olfactory stimuli evoke more AMs than verbal and visual stimuli. The conclusion section of the current review is devoted to some recommendations that might guide future research. For instance, stage-by-stage investigation of AM in AD and the comparison of them in relation to relevant variables could be one way of providing detailed findings on the nature of AM in AD.

Your Need for Cognition, Cognitive Flexibility, and Cognitive Emotion Regulation Strategies Matter! the Path Beyond a Satisfied Life
(Routledge Journals, Taylor & Francis Ltd, 2024) Kaynak, Hande; Nazligul, Merve Denizci; Cengil, Betul Beyza; Denizci Nazlıgül, Merve
This study explored the associations among cognitive flexibility, cognitive emotion regulation (CER) strategies, need for cognition, and life satisfaction, which represents a cognitive component of subjective well-being. Previous studies have shown the importance of adaptive CER strategies for well-being, while maladaptive strategies have been linked to negative outcomes such as psychological distress, depression, and anxiety. Additionally, the need for cognition has been associated with cognitive flexibility and positive outcomes in various domains. However, the specific roles of cognitive flexibility and CER strategies in the relationship between need for cognition and life satisfaction remain relatively unexplored in the existing literature. This study aimed to address this gap by investigating how cognitive flexibility and different CER strategies contribute to the relationship between need for cognition and life satisfaction in a non-clinical sample of 239 adults via a survey consisting of a demographic information form, need for cognition scale, cognitive flexibility inventory, cognitive emotion regulation questionnaire, and satisfaction with life scale. The results demonstrated that when individuals with a high need for cognition had cognitive flexibility, they were more likely to use adaptive cognitive emotion regulation strategies, resulting in elevated life satisfaction. The findings of this study may provide insights into the underlying mechanisms that influence individuals' cognitive processes, cognitive emotional regulation, and overall life satisfaction. Such understanding can have implications for interventions aimed at enhancing cognitive flexibility, promoting adaptive CER strategies, and ultimately fostering improved life satisfaction.
