Is the breadth of individualized ranges of optimal anxiety (IZOF) equal for all athletes? A graphical method for establishing IZOF.
2001
Recall and direct methods to determine the individual zone of optimal functioning (IZOF) cannot account for potential individual differences in the span of optimal anxiety. Accordingly, an attempt was made to test a graphical technique that could establish the span of optimal anxiety ranges for individuals. State anxiety (STAI; Spielberger, Gorusch, & Lushene, 1970; and CSAI-2; Martens, Burton, Vealey, Bump, & Smith, 1990) was assessed before competitions (10 to 20) in six Spanish golfers during a season. Performance in each match was determined using golf scores and self-ratings. Optimal anxiety ranges were established graphically by plotting individual scores of precompetition anx…
The role of perceptual information in familiarity-based scene recognition.
2012
A method to analyze the role of familiarity in recognizing pictures of everyday scenes is introduced. The idea is to manipulate two within-subjects conditions: an experimental condition where the scenes repeat perceptual information (e.g. buildings and/or vehicles) and a control condition. The results show the two conditions did not differ in terms of hit rates, but in the experimental condition there were significantly fewer false alarms, yielding better results, which supports the findings of past research studies that have used verbal materials. This perceptual facilitation was maintained throughout a week-long retention interval. Finally, a detailed analysis of this facilitation shows i…
Conscious knowledge and changes in performance in sequence learning: Evidence against dissociation.
1992
International audience; Two experiments examined the relation between explicit knowledge and motor performance on the serial reaction time task developed by Nissen and Bullemer (1987). Tests of free recall and recognition of sequence components revealed that reliable explicit knowledge was acquired after an amount of practice that was hardly sufficient to improve mean motor performance. In addition, reaction time improvement was limited to the ending trials of the 3- and 4-trial sequence components that Ss recalled or recognized. These results were replicated in Experiment 3, in which Ss were trained under attentional distraction in the task developed by Cohen, Ivry, and Keele (1990). Overa…
Familiarity-based recognition in the young, healthy elderly, mild cognitive impaired and Alzheimer's patients
2009
This study investigates the possible existence of deficits in familiarity in five samples of participants spanning a broad range of ages and cognitive states. Five groups of 16 participants with a diagnosis of multi-domain cognitive impairment with a slight or no deficit in memory, 16 multi-domain amnestic, and 16 Alzheimer's disease patients were compared in a recognition test with equivalent samples of old and young healthy participants. In one of the tests, participants studied words extracted from a restricted set of letters of the alphabet that were later mixed with new words from a different set. The unconscious use of the fluency produced by the repeated use of the set of letters was…
Animacy effects in episodic memory: do imagery processes really play a role?
2019
International audience; Animates are remembered better than inanimates because the former are ultimately more important for fitness than the latter. What, however, are the proximate mechanisms underpinning this effect? We focused on imagery processes as one proximate explanation. We tested whether animacy effects are related to the vividness of mental images (Study 1), or to the dynamic/motoric nature of mental images corresponding to animate words (Study 2). The findings showed that: (1) Animates are not estimated to be more vivid than inanimates; (2) The potentially more dynamic nature of the representations of animates does not seem to be a factor making animates more memorable than inan…
Frontal–posterior theta oscillations reflect memory retrieval during sentence comprehension
2015
Abstract Successful working-memory retrieval requires that items be retained as distinct units. At the neural level, it has been shown that theta-band oscillatory power increases with the number of to-be-distinguished items during working-memory retrieval. Here we hypothesized that during sentence comprehension, verbal-working-memory retrieval demands lead to increased theta power over frontal cortex, supposedly supporting the distinction amongst stored items during verbal-working-memory retrieval. Also, synchronicity may increase between the frontal cortex and the posterior cortex, with the latter supposedly supporting item retention. We operationalized retrieval by using pronouns, which r…
Rich false memories of autobiographical events can be reversed
2021
False memories of autobiographical events can create enormous problems in forensic settings (e.g., false accusations). While multiple studies succeeded in inducing false memories in interview settings, we present research trying to reverse this effect (and thereby reduce the potential damage) by means of two ecologically valid strategies. We first successfully implanted false memories for two plausible autobiographical events (suggested by the students’ parents, alongside two true events). Over three repeated interviews, participants developed false memories (measured by state-of-the-art coding) of the suggested events under minimally suggestive conditions (27%) and even more so using massi…
From "Non-encounters" to autonomic agency. Conceptions of patients with low back pain about their encounters in the health care system.
2018
Low back pain is a considerable health problem which affects people around the world, causing major healthcare costs. The use of qualitative research methods enables us to describe and understand patients' experience of, and attitudes to, healthcare. The aim of the present phenomenographic study was to identify and describe the contextual nature of the conceptions of patients with low back pain of their encounters in the HCS. Seventeen patients with chronic or episodic low back pain classified as "high risk" were interviewed in open recall interviews, using videos of patients' initial physiotherapy sessions that had been recorded previously. The data were analysed using the phenomenographic…
Bias in Studies of Parental Self-reported Occupational Exposure and Childhood Cancer
2003
Several case-control studies have demonstrated positive associations between parental occupational exposures and childhood cancer. However, an overestimation of risk estimates due to recall bias is of concern. The magnitude and nature of this bias were explored using data from a German case-control study on childhood leukemia conducted between 1992 and 1997. A moderate overreporting of occupational exposures by fathers was observed, particularly for the prenatal period. Overreporting was most apparent when the time between exposure and interview was short. It was also found that job titles were no satisfactory substitute for information on specific occupational exposures. The results of thi…
Selection of odorants for memory tests on the basis of familiarity, perceived complexity, pleasantness, similarity and identification
2002
In a procedure for the selection of two equivalent sets of familiar and two equivalent sets of unfamiliar odours for use in odour memory studies, 24 naive subjects were first asked to rate the familiarity, perceived complexity and pleasantness of 54 a priori unfamiliar odours and 57 a priori familiar odours and to identify the latter. After selection of the 40 most familiar and the 40 least familiar odours, the subjects sorted each of these two sets into groups of similar odours. Their results were analysed by multidimensional scaling and cluster analysis and each set was divided into two recognition sets that had the same degree of similarity between target and distractor odours and that h…
