In many earlier investigations a Recall advantage of auditory lists spoken in a single voice has been found over Recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes Recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice Recall would be better than Recall in order of presentation, as then the Recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.

AbstractTitle: Serial Recall of two-voice lists: Words are not perceptually organized by voice.The present study examined how voice affects the perceptual grouping of words in short-term memory that are auditory presented. Three different voice-lists were used: single-voice, alternating-voice and split-voice. In single-voice lists all words were presented in the same voice. In alternating-voice lists words were presented alternately in a male and a female voice. Finally, in split-voice lists words were presented grouped four and four in a male and a female voice.

The purpose of this thesis is to compare five different ranking algorithms for query expansion. The algorithms compared are f4, f4mod, porter, wpq, and emim. This is done using a TREC collection, a selection of topics, and relevance judgements. Relative Recall is measured before and after the expansion of the query. The study shows that all of the algorithms manage to increase the relative Recall, f4 being the one most successful..

In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.

Syftet med studien var att utreda om överraskningsmomentet inom reklamkampanjer gör att de som blivit exponerade lättare kommer ihåg namnet på varumärket. Undersökningsmetoden är kvantitativ och datan samlades in via enkäter. Vi trodde baserat på tidigare forskning att ett överraskningsmoment inom en reklamkampanj skulle hjälpa till att skapa ett högre brand Recall, vilket också blev fallet. Annonser som innehåller ett överraskningsmoment får ett större medvetande hos de som exponeras, det här leder till att de lättare kommer ihåg händelsen och de får därför ett högre brand Recall..

The current study sought to examine if post-produced semantic memory cues are a good aid for memory Recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with Recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory Recall. The results were discussed in regards to modern models describing semantic memory.

Does a person´s self esteem contribute in the process of creating false memories? Previous studies show that mood is related to false memories as well as to self esteem. This led to the focus of this study, to examine the relationship between false memory and self esteem. The question is examined by comparing the amount of false memories produced in the Deese-Roediger-McDermott (DRM) procedure with people´s scores on Rosenberg´s self-esteem scale. 59 people participated in a test with three different elements, a self esteem test and a memory test with both recollection and free Recall.

Syftet med studien var att genom ett kvalitetsarbete få en förståelse för gymnasieelevers upplevelser av sitt eget lärande i en konstnärlig, skapande process. Kvalitetsarbetet genomfördes på dansinriktningen vid ett estetiskt program i Norrbotten där jag under min verksamhetsförlagda utbildning lät eleverna arbeta individuellt med att skapa en koreografi, ett solo, som de senare redovisade. Soloredovisningarna filmades och inspelningen användes som minnesstimulerare vid de kvalitativa intervjuerna enligt metoden Stimuladed Recall. Resultatet visar att eleverna upplever ett lärande då de arbetar i en individuell, konstnärlig skapandeprocess. Eleverna uttrycker sin kunskap och sina förmågor med sin kropp, dock är det tydligt att eleverna med varierat resultat kan förmedla detta verbalt..

The aim of the present study was to investigate the effect of sensory modality on short-term memory Recall. An exploratory, cross-sectional study was performed. A total of 119 individuals participated. There were 70 female and 49 male subjects, aged 4 to 80 years (M=34,3). The participants were presented with 12 different objects in auditory, visual or auditory/visual mode over a period of 24 seconds.

Bakgrund:Awareness definieras som när en patient i generell anestesi i efterhand kan minnas händelser eller ha förnimmelser från en operation då han eller hon borde varit medvetslös. Det är en allvarlig anestesiologisk komplikation som kan leda till posttraumatiskt stressyndrom. Av de patienter som genomgår kirurgiska ingrepp i generell anestesi drabbas cirka 0,1 - 0,2 %. Den vanligaste orsaken till awareness är ytlig anestesi, vilket hos särskilda riskpatienter ibland kan vara svårt att förebygga med endast traditionell övervakning. Det finns därför ytterligare metoder att tillgå.

The aim of this thesis was to evaluate the music downloading service Musikwebb regarding its indexing and retrieval effectiveness. This was done by performing various kinds of search in the system. The outcome of these searches were then analysed according to the criteria specificity, precision, Recall, exclusivity and authority control. The study showed that Musikwebb had several flaws regarding its retrieval effectiveness. The most prominent cases were the criteria exclusivity and specificity.

In query expansion (QE) terms are added to an initial query in order to improve retrieval effectiveness. In this thesis we use QE in the sense that a reformulation of the query is done by deleting the terms in the initial query and instead replacing them with terms from the documents retrieved in the initial run. The aim of this thesis is to, in a experimental full text invironment, study and compare the retrieval result of two different query expansion strategies in relation to each other. The following questions are addressed by the study: How do the two strategies perform in relation to each other regarding Recall? What may be causing the result? Are the two strategies retrieving the same relevant documents? Two strategies are designed to simulate a searcher using automatic query expansion (AQE) either with or without relevance feedback.
