Serial position effects in implicit memory for multiple-digit numbers

Serial position effects in implicit and explicit memory were investigated in a short-term memory task. A study list composed of four, spatially distributed, two-digit numbers was presented, followed by an item recognition task (explicit test) and an implicit memory task in which participants were asked to verify a simple addition equation where the presented answer was either primed or not primed by one of the number pairs in the study list. Similar serial position effects were observed in explicit and implicit memory, with faster response times for correct decisions on the first than on the later list positions. The presence of a primacy effect but no recency effect is consistent with previous studies of explicit memory with visual presentation. The results suggest that similar principles of temporal information processing govern priming and episodic short-term memory.     

Determination of problems in patients with post‐laryngectomy

The purpose of this study is the determination of the physical and psychosocial problems of total and partial laryngectomies. A total of 25 patients, who were operated with the diagnosis of larynx carcinoma in 2010 at Gazi University Faculty of Medicine Otolaryngology Department, were included in the study. They were evaluated with the help of the Personal Information Form (PIF) and the Determination Form of Post Laryngectomy Problem (DFPLP) for the problems they encountered after the operation. Total laryngectomy (TL) was performed on 76% of patients. It was determined that patients undergoing total laryngectomy experienced some physical and psycho‐social problems such as problems in sleep (31.6%), smell (52.6%), taste (36.8%), and difficulty in swallowing solid foods (36.8%). Furthermore in patients with TL surgery whilst 47.4% of them think that their sexual lives were affected rather negatively, this rate was determined as 33.3% in patients with partial laryngectomy surgery (PL). The psychosocial score averages of the patients who had smell and taste disorders were significantly lower (p < 0.05). The patients, who underwent a laryngectomy operation, experienced many physical, social, and psychological problems. Thus, medical personnel also need to pay attention to these concomitant problems that occur during the treatment of the primary disease and the application of necessary supplementary treatments such as voice prosthesis, pre‐op and post‐op counseling, and anti‐depressants seems significant in terms of increasing the life quality of the patients.     

Serial position effects in implicit memory

Serial position effects in explicit and implicit memory were investigated in a noncolour word Stroop task. Participants were presented with a study list of four words printed in different colours and were tested for memory of the list position of the colour (explicit memory task); they were then asked to complete a word stem primed (or not primed) by one of the words in the study list (implicit memory task), a task presented as a distractor task. Serial position effects were observed in both explicit and implicit memory, for both response times and proportion of correct responses, with marked primacy effects, a drop in performance towards the third list position and a rise in memory performance at the fourth list position, the recency effect being most pronounced in implicit memory. It is concluded that explicit and implicit expressions of memory are governed by similar principles of temporal information processing.     

Item-specific effects in recognition failure: Reasons for rejection of the Tulving-Wiseman function

The present paper addresses the problems of whether recognition failure of recallable words is a function of both recognition and recall, and whether recognition failure is restricted to a small and specifiable subset of study items. A meta-analysis of the Nilsson—Gardiner database (Nilsson & Gardiner, 1993) showed that recognition given recall was positively correlated with recognition and negatively correlated with recall. Two new experiments are reported, the first one using 48 word pairs for which recognition failure was found in previous studies. An item analysis of the data demonstrated that recognition failure occurred primarily with noun—adjective pairs. The second experiment compared Norwegian—American and American—Norwegian name pairs. Wide deviation from the Tulving—Wiseman function (Tulving & Wiseman, 1975) was observed for the latter condition. In both conditions, recognition failure occurred with only the items for which the beginnings of names shared three or more letters. It is concluded that recognition failure occurs when there exists a relationship between the members of an A—B pair that is independent of their pairing in the study context. The Tulving—Wiseman function is the result of collapsing across items in the analysis of previous studies.
