9 Scope of Life I was born 1973 of August in a small village of Ankara, Turkey. I finished primary, secondary and high schools in Ankara, also. My university education lasted longer than usual because of my curiosity to different disciplines especially to the biology and cognitive sciences. Amazed by the secrecy of life and complexity of brain, I find readings and works about the brain related material always very interesting. I have also one clear acceptation (motto) regarding to the mind/brain: to understand the mind, all about the functions generated by the organ of brain such as sensing, perceiving, understanding, deciding, acting, thinking, and feeling (emotions) have organic basis, that is organ of brain. Mind is an emergent property of complexity of synapses in neural networks. Secrecy of mind is a matter of computational power. In the graduate years, I also took courses from the cognitive sciences and statistics. My thesis was about the electrophysiology of expectation phenomena. During expectation, there was alpha and theta synchronization (unpublished) prior to expected event. On the other hand, in my PhD, I tried to get the answer to the question about whether the memory enhancement effect of the emotional stimuli was preserved in Alzheimer s disease patients. Currently, I am employed in Psychology Department of Hacettepe University as lecturer. I have teaching courses such as Introduction to Psychology, Learning, Cognitive Neuroscience, Statistics in Psychology, and Research Methods.
10 Doctoral Dissertation (PhD in Experimental Psychology, In Press) ABSTRACT BARAN, Zeynel. Comparison of Emotional Memory Performances among Young, Healthy Elder, and Alzheimer s Type Dementia Groups, Doctoral Dissertation, Ankara, The main aim of this study is to reveal factors that can affect the emotional memory performance and to indicate how this performance is being affected in Alzheimer s Type Dementia (ATD), a disorder characterized with aging and immense memory loss. With respect to this purpose, two experimental studies are designed. In the Experiment I, emotional valence (pleasant, neutral and unpleasant) of pictures and words are manipulated in order to examine the results of this manipulation on emotional performance indexed by measurements such as encoding, free recall, recognition, and reaction times. The effect of emotional contexts produced by words for pictures and vice versa on encoding and memory measurements are also tested. In the Experiment II, how subliminal (SB) and supraliminal (SP) presentations and emotional valence of the context affect implicit and explicit memories are also studied. Experiment I consists of 90 participants in three groups as young (30), healthy elder (30), and ATD (30) groups. On the other hand, Experiment II has 30 young participants at the each of SB and SP conditions. In Experiment I, Emotional Memory Battery consist of 63 pictures (pleasant, neutral and unpleasant) chosen from International Affective Picture System (IAPS) and 63 adjective words (pleasant, neutral and unpleasant) are used. In Experiment II, 24 of pictures (8 pleasant, 8 neutral and 8 unpleasant) are selected in Experiment I. For this part of the study 24 different nouns (all concrete) are used. For Experiment I, all dependent variable measurements were analysed with 3(Group: Young, healthy elder and ATD) x 3(Emotional Valence of Picture: Pleasant, neutral and unpleasant) x 3(Emotional Valence of Word: Pleasant, neutral and unpleasant) mixed ANOVA design repeated at last two factors. For Experiment II, all dependent variable measurements were analysed with 2(Presentation Type: Subliminal and Supraliminal) x 3(Emotional Valence: Pleasant, neutral and unpleasant) mixed ANOVA design repeated at last factor. Bonferroni correction was applied in post hoc comparisons. Data was collected with 15 inch laptop computer.
11 Analyses indicate that memory enhancement effect was there for all three groups including ATD. Generally, context that was produced by negative stimuli affected emotional memory performance more and in a better way than other context types such as positive and neutral ones. In addition, participants remembrance scores were better if both context and stimulus were congruent than incongruent. Also, reaction times of participants to pleasant stimuli were quick but unpleasant ones were slow. Pictures had superior remembrance scores than words. In Experiment II, Word Stem Completion Task scores are higher in SP condition than SB condition. At both conditions, participants completed more words if the words had been previously showed with negative pictures than had been showed with pozitive or neutral pictures. Therefore, priming effect was higher for words presented with negative pictures than other word-picture combinations. Results provide supports to the fact that levels of processing theory can explain findings in implicit tasks such as word stem completion task. Results of the study are discussed with respect to Socioemotional Selectivity Theory, emotional memory enhancement effect and levels of processing theory. Key Words: Emotional Memory, Emotional Context Effect, Memory Enhancement Effect, Positivity Bias, Negativity Bias, IAPS, Alzheimer s Type Dementia, Subliminal Presentation, Word Stem Coxpletion Task, Levels of Processing Theory
12 Master Thesis (Unpublished) Baran, Z. (2006). The Effects of the Expectancy on the Event-Related Potentials and Event- Related Oscillations Recorded from the Brain (Master s thesis). Hacettepe University, Ankara, Turkey. ABSTRACT BARAN, Zeynel. Effects of the Expectancy on the Event-Related Potentials and Event- Related Oscillations Recorded from Brain, Master Thesis, Ankara, Anticipating incoming events and exhibiting response or response sets are crucial to the survival of organisms. The expectancy that is developed when anticipating an event is important both for processes related to the perception of the event and processes related to the selection of the appropriate motor response. The aim of the study was to investigate the electrophysiological basis of expectation in an organism with a high level of cognitive capacity, such as in the humans. Brain s electrophysiology was studied in the present study in the form of event-related potentials (ERPs) and event-related oscillations (EROs). The sample consisted of 33 healthy, right handed university students (18 females and 15 males). To create expectancy effect, the 5 th stimulus after every 4 th stimulus was omitted in all the following four paradigms. In two of the paradigms (S1/BP, S4/BP), sinusoidal pure tones were used as stimulus. In the other two paradigms (M1/BP and M4/BP), meaningful stimuli were used. Pure tones had 0.5 s duration and 65 db sound pressure level. In S1/BP, pure tones were in one of the following frequencies: 1500 Hz, 2000 Hz, 2500 Hz ve 3000 Hz. In S4/BP, all four frequencies were used in four different patterns. For the meaningful stimuli, four verses of a poem were used. In M1/BP one verse of the poem was used; in M4/BP, all four verses were used. Duration of the words and the sound pressure levels could change for each word (62-65 db) because of prosody effect. The task of the participants was to guess the time point of the 5 th omitted stimulus. Electrophysiological recordings were taken using a 32-channel preamplificator. The electrodes were made of sintered Ag-Ag/Cl and referenced to the linked mastoids. Recordings were filtered online between 0.1 Hz and 100 Hz (3 db down, 12 db / oct) at an analog-digital conversion rate of 500 Hz.
13 Discriminant analyses showed that N100 had the highest predictive value for levels of the paradigm at Fz and Cz electrode locations; and P300 and N200 components had the highest predictive value at the Pz electrode location. These findings support the findings in the related literature according to which the N100 component is related to passive and indirectly to also the active attention. P300 amplitude increased from the 2nd stimulus to the 4th stimulus at the Pz electrode location. This change suggested an increased focused attention and readiness to respond as the time of the omitted stimulus approaches. N400 component showed a frontocentral distribution and its amplitude decreased as the 4th stimulus approached. These findings suggested that N400 reflects complex stimulus evaluation and processes related to memory search and scan. Phase-reordering was found at the alpha and theta bands. This indicates that participants can produce omitted stimulus internally at the time point where stimulus should have occurred. Power spectral analysis of the total recording time showed that theta power decreased from 2nd to the 4th stimulus. However, alpha 1 power increased from the 2nd to the 4th stimulus. However, analyses covering only the prestimulus period showed that both theta and the alpha power increased from the 2nd stimulus to the 4th stimulus. These results showed that increased readiness to respond and expectation state of the brain as the time point of the omitted stimulus approaches can be represented not only by the by the event-related potentials but also the event-related oscillations of the brain.
