    The time course of resource allocation in spider-fearful participants during fear reactions2008Inngår i: Cognition & Emotion, ISSN 0269-9931, E-ISSN 1464-0600, Vol. 22, nr 7, s. 1381-1400Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The dynamics of resource allocation to pictures of spiders and other animals in spider-fearful participants was investigated. The task of the participants was to respond rapidly and accurately to various probe stimuli superimposed on pictures of different animals. These were arguably fear relevant (spiders, snakes, and wolves) and fear irrelevant (beetles, turtles, and rabbits). The probes were shown with different stimulus onset asynchronies (SOAs) from picture onset to address the dynamics of resource allocation. A larger allocation of resources to spider pictures than to pictures of all other animals, with no difference between the latter regarding resource allocation was found. For the task that demanded more resources the fearrelated physiological responses decreased, suggesting that controlled processing modulates fear responses.

    Tracking fear in snake and spider fearful participants during visual search: a multi-response domain study2006Inngår i: Cognition & Emotion, ISSN 0269-9931, E-ISSN 1464-0600, Vol. 20, nr 8, s. 1075-1091Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In visual search tasks snake or spider fearful participants showed shorter reaction times (RTs) to respond to their feared animal (e.g., snake) than to the nonfeared animal (i.e., spider) (Öhman, Flykt, & Esteves, 2001). Here, we used this paradigm with heart rate (HR), RTs, and event-related potential (ERP) measures, to investigate the nature of the responses to the feared animal, a nonfeared (but fear-relevant) animal, and fear-irrelevant target stimuli with snake fearful, spider fearful, and nonfearful participants. Fearful participants showed shorter RTs and evoked larger amplitudes on a late positive potential (LPP; 500-700 ms) for their feared compared to the nonfeared and the fear-irrelevant targets. No relevant significant differences were found on early ERP components and HR measures. These findings do not support an involvement of early information processing in the detection of the feared animal in fearful participants, they favour instead a more elaborated analysis of these complex stimuli to achieve the detection.

    What determines a feeling's position in affective space?: a case for appraisal2006Inngår i: Cognition & Emotion, ISSN 0269-9931, E-ISSN 1464-0600, Vol. 20, nr 1, s. 92-113Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The location of verbally reported feelings in a three-dimensional affective space is determined by the results of appraisal processes that elicit the respective states. One group of participants rated their evaluation of 59 pictures from the International Affective Picture System (IAPS) on a profile of nine appraisal criteria. Another group rated their affective reactions to the same pictures on the classic dimensions of affective meaning (valence, arousal, potency). The ratings on the affect dimensions correlate differentially with specific appraisal ratings. These results can be interpreted as showing that the reactions to the IAPS pictures are predictably produced through appraisal of picture content. The relevance of the findings for emotion induction paradigms and for emotion theory in general is discussed.
