Cognitive Reserve and Emotional Stimuli in Older Individuals: Level of Education Moderates the Age-Related Positivity Effect
(TAYLOR & FRANCIS INC, 2014) Davide Bruno; Adam D. Brown; Aycan Kapucu; Charles R. Marmar; Nunzio Pomara; Pomara, Nunzio; Marmar, Charles R.; Bruno, Davide; Kapucu, Aycan; Brown, Adam D.
Background/Study Context: A frequently observed age-related effect is a preference in older individuals for positive stimuli. The cognitive control model proposes that this positivity effect may be mediated by executive functions. We propose that cognitive reserve operationally defined as years of education which tempers cognitive decline and has been linked to executive functions should also influence the age-related positivity effect especially as age advances. Methods: An emotional free recall test was administered to a group of 84 cognitively intact individuals aged 60 to 88 who varied in years of education. As part of a larger test battery data were obtained on measures of executive functioning and depression. Results: Multiple regression and moderation analyses were performed controlling for general cognitive function severity of depressive symptoms and executive function. In our data years of education appeared to moderate the effect of age on the positivity effect, age was negatively associated with recall of positive words in participants with fewer years of education whereas a nonsignificant positive correlation was observed between age and positivity in participants with more education. Conclusion: Cognitive reserve appears to play a role in explaining individual differences in the positivity effect in healthy older individuals. Future studies should investigate whether cognitive reserve is also implicated in the ability to process a wide range of emotional stimuli and whether greater reserve is reflected in improved emotional regulation.

Effects of self-referencing on feeling-of-knowing accuracy and recollective experience
(ROUTLEDGE JOURNALS TAYLOR & FRANCIS LTD, 2015) Aysecan Boduroglu; Didem Pehlivanoglu; Ali I. Tekcan; Aycan Kapucu; Pehlivanoglu, Didem; Boduroglu, Aysecan; Kapucu, Aycan; Tekcan, Ali I.
The current research investigated the impact of self-referencing (SR) on feeling-of-knowing (FOK) judgements to improve our understanding of the mechanisms underlying these metamemory judgements and specifically test the relationship between recollective experiences and FOK accuracy within the accessibility framework FOK judgements are thought to be by-products of the retrieval process and are therefore closely related to memory performance. Because relating information to one's self is one of the factors enhancing memory performance we investigated the effect of self-related encoding on FOK accuracy and recollective experience. We compared performance on this condition to a separate deep processing condition in which participants reported the frequency of occurrence of pairs of words. Participants encoded pairs of words incidentally and following a delay interval they attempted at retrieving each target prompted by its cue. Then they were re-presented with all cues and asked to provide FOK ratings regarding their likelihood of recognising the targets amongst distractors. Finally they were given a surprise recognition task in which following each response they identified whether the response was remembered known or just guessed. Our results showed that only SR at encoding resulted in better memory higher FOK accuracy and increased recollective experience.

Introduction: To identify dysfunctional attitudes seen in bipolar disorder (BPD) is important for the cognitive theories of BPD and corresponding psychosocial interventions. Cognitions are seen as vulnerability factors in the development and maintenance of BPD. The present study aims to contribute to the cognitive literature on BPD by examining depressive and hypomanic attitudes and their contribution to the prediction of BPD diagnosis as well as by exploring the relationship between dysfunctional cognitions and clinical features (types of episodes experienced duration of illness and duration of remission). Methods: One hundred and eighteen remitted bipolar patients and 103 healthy controls completed the Mood Disorder Questionnaire (MDQ) Turkish Brief-Hypomanic Interpretations and Positive Predictions Inventory (HAPPI) and Dysfunctional Attitudes Scale. Results: The bipolar group had significantly higher depressive and hypomanic attitudes than the control group. No significant differences were found regarding the types of episodes experienced and duration of illness. However both types of attitudes decreased as the duration of remission increased. They were also found to contribute to the prediction of bipolar diagnosis together with the screening of the MDQ. Conclusion: The results pointed out that dysfunctional cognitions may be utilized as possible indicators for the risk of relapse in clinical groups and vulnerability for BPD among other populations.

Memory bias for negative emotional words in recognition memory is driven by effects of category membership
(ROUTLEDGE JOURNALS TAYLOR & FRANCIS LTD, 2014) Corey N. White; Aycan Kapucu; Davide Bruno; Caren M. Rotello; Roger Ratcliff; White, Corey N.; Ratcliff, Roger; Kapucu, Aycan; Bruno, Davide; Rotello, Caren M.
Recognition memory studies often find that emotional items are more likely than neutral items to be labelled as studied. Previous work suggests this bias is driven by increased memory strength/familiarity for emotional items. We explored strength and bias interpretations of this effect with the conjecture that emotional stimuli might seem more familiar because they share features with studied items from the same category. Categorical effects were manipulated in a recognition task by presenting lists with a small medium or large proportion of emotional words. The liberal memory bias for emotional words was only observed when a medium or large proportion of categorised words were presented in the lists. Similar though weaker effects were observed with categorised words that were not emotional (animal names). These results suggest that liberal memory bias for emotional items may be largely driven by effects of category membership.

Modeling the Effect of Mood on Dimensional Attention During Categorization
(AMER PSYCHOLOGICAL ASSOC, 2013) Matthew T. Zivot; Andrew L. Cohen; Aycan Kapucu; Cohen, Andrew L.; Kapucu, Aycan; Zivot, Matthew T.
Classification is a flexible process that can be affected by mood. The goal of this paper is to evaluate the idea that mood may modulate categorization behavior through an attentional weighting mechanism in which mood changes the attention afforded to different stimulus dimensions. In two experiments participants learn and are tested on categories while in a calm or sad mood. In Experiment 1 sad participants are faster to learn one- and two-dimensional category structures but show no advantage on a three-dimensional category structure. In Experiment 2 the generalized context model of categorization is used to measure dimensional weighting. The results suggest that sad participants have a narrower focus of attention but that the narrowing tends to be on diagnostic dimensions.

The relationship between executive functions episodic feeling-of-knowing and confidence judgements
(ROUTLEDGE JOURNALS TAYLOR & FRANCIS LTD, 2014) Aysecan Boduroglu; Ali I. Tekcan; Aycan Kapucu; Boduroglu, Aysecan; Kapucu, Aycan; Tekcan, Ali I.
Metamemory processes and executive control may be related given that both are frontally mediated. However previous behavioural research has been limited in identifying common processes driving this somewhat weak relationship partly because they mostly relied upon global executive measures and composite scores of executive function (EF). The present study investigated the relationship between specific EFs (task shifting interference resolution) working memory capacity and feeling-of-knowing (FOK) and confidence judgements (CONF) in an episodic memory task. We found that of the EFs only task-switching performance was correlated with FOK accuracy and proposed a shared mechanism that may be at play in both task-switching and FOK judgements. We also demonstrated that interference resolution and episodic memory measures were related suggesting strategic influences on memory retrieval. Finally we found a strong consistency in the strength and accuracy of FOK and CONF judgements possibly due to retrieval-based mechanisms in both types of judgements.
