Ben bu kitabin cok degerli oldugunu dusunuyorum. Kitabin ilk bolumunu oldukca onemli buldum,gereksiz oldugunu dusunmuyorum. Ilk bolum bilimsel metodolojilerden bahsetmis, ikinci bolum de bu bilimsel metodolojilere atif yaparak, Ataturk'un bilimsel temelleri olan bir politik metodoloji kullandigi anlatilmis. Bilimsel metodolojiden anlamayanlar icin ilk bolum oldukca faydali olabilir. Kritize edebilecegim tek nokta "diktator" kelimesinin kullanimi olabilir. Ataturk'un diktalarini ikna yoluyla yapmasi diktatorluk diye tanimlanmis. Onun yerine baska bir kelime kullanilabilirdi belki, ancak elbette ona benzer baska bir yonetim bicimi olmadigi icin diktatorluk olarak kullanilmis. Belki diktatorlugun bir alt grubu diye tanimlanabilirdi. Ben "diktator" kelimesini cok guclu buldugumdan, biraz mecazi anlamda oldugunu dusunmeden edemedim. Kitabi okumanizi tavsiye ederim.

Abstract Repeated display configurations improve visual search. Recently, the question has arisen whether this contextual cueing effect (Chun & Jiang,  1998 ) is itself mediated by attention, both in terms of selectivity and processing resources deployed. While it is accepted that selective attention modulates contextual cueing (Jiang & Leung, 2005 ), there is an ongoing debate whether the cueing effect is affected by a secondary working memory (WM) task, specifically at which stage WM influences the cueing effect: the acquisition of configural associations (e.g., Travis, Mattingley, & Dux,  2013 ) versus the expression of learned associations (e.g., Manginelli, Langer, Klose, & Pollmann,  2013 ). The present study re-investigated this issue. Observers performed a visual search in combination with a spatial WM task. The latter was applied on either early or late search trials—so as to examine whether WM load hampers the acquisition of or retrieval from c...

Abstract: This study examined the relations between explicit and implicit measures of visual-spatial memory (i.e., separate vs. unique memory system hypotheses; cf., e.g., Henke, 2010); whether spatial long-term memory is, as it has been shown at least for spatial short-term memory (i.e., visual imagery, Vandenberg & Kuse, 1978) modulated by gender; and how the formation of spatial long-term memory is influenced by perceptual grouping (cf. Geyer, Shi, & Müller, 2010). To examine this, 20 observers (10 female) participated in both a spatial working memory task (sWMT - the original version of mental rotation task developed by Shepard & Metzler (1971) and visual search task (contextual cueing task) , with the latter having shown repeatedly for being aided by spatial long-term memory (sLTM; cf. Chun & Jiang,1998). Results showed that (1) in ‘default’ mode, contextual cueing is modulated by color, rather than, space-based grouping.  (2) Contextual cueing is modulated b...
