Tidskriftsartikel (refereegranskat)abstract
- This study investigated the relation between personality factors, as measured by the Swedish version of the NEO-FFI questionnaire, and the realism in older adults' (aged 60-93 years, n = 1,384) probability confidence judgements of their answers to general knowledge questions. The results showed very small effect sizes for the contribution of the personality variables to the fit between the proportion correct answers and the level of one's confidence judgements. Although personality differed somewhat within the age span studied and between the genders no differences were found in the relation between the dimensions of the NEO-FFI and the degree of realism in the confidence judgements as a function of age or gender. In total, the results show a significant but very small effect of personality on the realism in older adults' confidence judgements of their semantic knowledge.

Tidskriftsartikel (refereegranskat)abstract
- The study investigated 2 aspects of the accuracy (i.e., realism) of confidence judgments of persons age 60–93 years (N 1,384) regarding their answers to general knowledge questions. These aspects are the level of confidence (calibration) in relation to the proportion of correct answers and the ability to discriminate between correct and incorrect answers by means of confidence judgments. No age differences were found for either of the 2 aspects. Gender differences were found for proportion of correct answers and confidence but not for the realism in the confidence judgments.

The relation between realism in confidence judgements and the phenomenological quality of recognition memory when using emotionally valenced pictures

Tidskriftsartikel (refereegranskat)abstract
- The aim of the study was to investigate the relation between the phenomenological quality of memory (Tulving, 1985) and the realism (validity) in confidence judgement when using emotional pictures (I.A.P.S; Lang, Ohman, & Vaitl, 1988). A series of three experiments was completed where the participants judged the phenomenological quality of their memory and/or their confidence. The results showed facilitation for the negative pictures in a matrix search task in the encoding phase, where negative pictures were more easily and quickly detected, compared to positive ones. In the memory phase of the experiments a higher degree of recollective experience (a larger proportion of 'remember' responses) was found for negative pictures. A higher level of confidence for recognition of negative pictures than for positive ones was obtained, but no general valence dependent effect on the realism in the confidence judgement was found. However, when analysing only the remember responses, negative pictures showed higher overconfidence than the positive pictures. The results support that a recollective experience induces higher confidence and overconfidence.

The effect of emotional valance on recollective experience and confidence judgments
- 2003

Ingår i: ; , s. 110-110

Konferensbidrag (refereegranskat)abstract
- The study investigated the effect of positive and negative emotional valence (I.A.P.S pictures) on recollective experience, using the remember-know paradigm (Tulving, 1985), and confidence judgements. The negative valenced pictures were hypothesised elicit the recollective experience to a larger extent and to entail a higher degree of confidence in the correctness of memory responses than positive valenced pictures. In the acquisition phase of all three experiments four pictures were presented simultaneously, one valenced picture (either positive or negative) and three neutral pictures. Next, in the test phase a recognition test of the valenced pictures followed. Depending on the experiment, the participants made new/old responses and either remember/know judgements of old responses or confidence judgements of the correctness of their new/old responses. The results of Experiment 1 and 2 showed that, compared with ”know” responses, the frequency of ”remember” responses was significantly higher for negative than for positive pictures. No differences in recognition memory performance were found between negative and positive pictures. The results of Experiment 3 showed that negative pictures was associated with slightly higher accuracy and significantly higher confidence judgements than positive pictures, and that realism in confidence judgements did not differ between the valence types. These results suggest that the emotional valence of witnessed events affect the phenomenological quality and degree of confidence of memorial testimony.

Processing Asymmetries of Emotionally Valenced Stimuli
- 2002
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The central phenomenon investigated concerns the valence-based process asymmetry found in several earlier studies (e.g. Pratto & John, 1991; Taylor, 1991), where negative stimuli seem to initiate more thorough processing than positive stimuli. This finding was consistent in the three empirical studies forming this dissertation. In Study 1 (three experiments) emotionally valenced words were presented at the centre of pictures of emotional faces (angry, sad, disgusted, happy). The results showed a general positive valence advantage (PVA) in reaction times for positive words relative to negative words. Furthermore, except for the words imposed on pictures of angry faces in the first experiment, the PVA increased when words were imposed on pictures of happy faces. In Study 2, the priming effects of emotional words were tested. In both experiments, two conditions were used. When valence had been activated by a valence categorisation task, negatively primed words resulted in prolonged RTs in a subsequent word recognition test. In the other condition, where the participants just read the word, no valence dependent latency differences were found. The results provide support for a non-automatic appraisal of the valence when using words as stimuli.In Study 3 (three experiments) neutral words were imposed on emotional pictures (negative, neutral and positive) in the encoding phase. In the following test phase the phenomenological quality of the memory was measured using the Remember-Know paradigm (Tulving, 1985). The results showed a decrease in the frequency of “remember” responses, suggesting less episodic detail in the retention experience of the to-be-remembered item, when the words had been presented on negative pictures relative to positive pictures. The third experiment tested whether the neutral words were primed by the valence of the encoding context (picture) and whether such affective information could be used as a cue in a subsequent source monitoring task (Johnson, Hashtroudi, Lindsay, 1993). However, no support for the valence-as-a-cue hypothesis was found. The results of the three studies are discussed within the framework of appraisal theories (Lazarus, 1991; Scherer, 2001) and Taylor’s mobilization-minimization hypothesis, and an evolutionary explanation for the processing asymmetry is considered.

Judging words at face value : interference in a word processing task reveals automatic processing of affective facial expressions
- 1998
-
Ingår i: Cognition & Emotion. - 0269-9931 .- 1464-0600. ; 12:6, s. 755-782

Tidskriftsartikel (refereegranskat)abstract
- Earlier research has indicated that some characteristics of facial expressions may be automatically processed. This study investigated automaticity as evidenced by involuntary interference in a word evaluation task. Compound stimuli, consisting of words superimposed on pictures of affective faces, were presented to subjects who were given the task of evaluating the affective valence of the words while disregarding the faces. Results of three experiments showed that word evaluation was influenced by the concurrently shown affective faces. Overall, negative words were found to require longer latencies, indicating that more processing resources are invested in negative than in positive stimuli. This speed advantage for positive words was modified by the faces. Negative words were facilitated, relative to positive ones, when shown with a negative expression, e.g. a sad face. Correspondingly, negative words were inhibited, relative to positive ones, when shown with a positive expression, e.g. a happy face. The results are consistent with automatic, involuntary semantic processing of affective facial expressions.
