  • ERIC: altijd veel ruis. Komt door grijze literatuur (peer review limit gebruiken!). Wel handig op gebied van onderwijskunde, zeker ivm thesaurusMedline: ik gebruik de ‘in process’-versie. Omdat ik meestal zowel PsycINFO als ERIC gebruik is het makkelijker om in dezelfde interface te blijven (vooral mbt mijn klanten)EMBASE: bijna altijd nuttige aanvulling. Ik ga alleen naar het AMC als daar een goeie reden voor is (mneuropees onderzoek). Op gebied van psychologische onderwerpen betere thesaurus dan MedlineCINAHL: aardige aanvulling tot nu toe. Viel niet tegen (search licht therapie en slaapstoornissen)LLBA: vreselijk omdat het de Proquest interface betrof, thesaurus zeer gebruiksonvriendelijk en lang niet zo goed ontsloten als PsycINFO, Medline etc. Sociological Abstracts: zie LLBA + In onderwijssetting stelt sociological abstracts vaak teleur omdat ze belangrijke werken lijken te missen. Dit komt denk ik deels door de gedeelde markt met SocINDEX en IBSS. Daarnaast wordt SA slechts maandelijks geupdate en bevat het krap 1 miljoen titels. Wat wel goed bevalt (en waarvoor ik het ook gebruik) is het genereren van zoektermen.EPPI: Marike?
  • Let op: je blijft zelf verantwoordelijk voor de correctheid van je referenties. Refworks en zoekmachines kunnen dit niet geheel foutloos.

  • 9. Snake PhobiaAbstract Using a visual search methodology we investigated the effect of feared animal stimuli on attention. Our results confirmed the important role of emotion on attention. All participants detected fear-relevant stimuli (snakes and spiders) faster than neutral (mushrooms) ones against a background of fruits. In addition, spider fearful participants were sensitized specifically to detect their feared stimulus (spiders), compared to their fear-relevant but non-feared (snakes) and neutral stimuli. However, for participants fearful of snakes there was no significant difference in detection latencies between the feared (snakes) and the fear-relevant but non-feared animal stimuli (spiders). The results from the attention task were mirrored in the emotional ratings, which showed that spider fear was highly specific, whereas snake fear was associated with a more generalized enhanced evaluation of all negative stimuli.
