    Anxiety in elderly hearing impaired persons1995In: Perceptual and Motor Skills, ISSN 0031-5125, E-ISSN 1558-688X, ISSN 0031-5125, Vol. 81, p. 552-554Article in journal (Refereed)

    Abstract

    The association between experiences of hearing impairment and signs of anxiety in 42 elderly hearing impaired patients at a hearing aid centre was investigated. Subjects completed the Hearing Coping Assessment, the Beck Anxiety Inventory, and an audiometric test of hearing. Analysis showed low scores on anxiety and hearing problems compared with other studies. Moreover, scores on anxiety did not correlate with pure tone thresholds for hearing but with self-reported hearing problems (r = .31). Anxiety is important, but it is possible that signs of depression are more strongly related to self-perceived hearing handicap.

    Fixation identification in centroid versus start-point modes using eye-tracking data2008In: Perceptual and Motor Skills, ISSN 0031-5125, E-ISSN 1558-688X, Vol. 106, no 3, p. 710-724Article in journal (Refereed)
    Abstract [en]

    Fixation-identification algorithms, needed for analyses of eye movements, may typically be separated into three categories, viz. (i) velocity-based algorithms, (ii) area-based algorithms, and (iii) dispersion-based algorithms. Dispersion-based algorithms are commonly used but this application introduces some difficulties, one being optimization. Basically, there are two modes to reach this goal of optimization, viz., the start-point mode and the centroid mode. The aim of the present study was to compare and evaluate these two dispersion-based algorithms. Manual inspections were made of 1,400 fixations in each mode. Odds ratios showed that by using the centroid mode for fixation detection, a valid fixation is 2.86 times more likely to be identified than by using the start-point mode. Moreover, the algorithm based on centroid mode dispersion showed a good interpretation speed, accuracy, robustness, and ease of implementation, as well as adequate parameter settings.

    Conceptual confusion and potential advances in athlete burnout research2016In: Perceptual and Motor Skills, ISSN 0031-5125, E-ISSN 1558-688X, Vol. 123, no 3, p. 784-791Article in journal (Refereed)
    Abstract [en]

    More than 30 years of research on athlete burnout has yielded important insights and questions regarding the onset, nature, and consequences of this detrimental syndrome. Not surprisingly, burnout is considered an important matter, both from a research and practical standpoint. We comment on the work of Ryu, Ali, Kim, Choi, and Radlo, who examined the impact of burnout on cognitive performance among athletes.

    INFORMATION AND REPETITION CHANGE CHILDRENS VISUAL STRATEGIES WHEN VIEWING MAGIC TRICKS WITH AND WITHOUT GAZE CUES2013In: Perceptual and Motor Skills, ISSN 0031-5125, E-ISSN 1558-688X, Vol. 116, no 1, p. 144-162Article in journal (Refereed)
    Abstract [en]

    Gaze cues and direct gaze attract visual attention. However, few studies have explored visual cues in children within realistic contexts. The effect of information and repetitive stimulus presentation has not been thoroughly studied with dynamic stimuli. The aim of the present study was to investigate how information affects the visual strategies of children measured by the number of fixations on certain areas of interest and their durations. Furthermore, this study examined the effect of gaze cues and direct gaze. In two consecutive experiments, childrens visual strategies when viewing magic tricks were measured by an eye tracker. Gaze cues were only present in Experiment 1. The results showed that repetitive stimulus presentation and information caused children to change their visual strategies when viewing magic tricks with and without gaze cues. However, the effect was larger when the gaze cues were not present. These findings in children were similar to those in adults.

    Inner images and delineations of parental figures reported by psychotherapeutic outpatients2006In: Perceptual and Motor Skills, ISSN 0031-5125, E-ISSN 1558-688X, Vol. 103, no 3, p. 931-945Article in journal (Refereed)
    Abstract [en]

    Psychotherapeutic outpatients (10 men, 20 women) were tested with the Inner Images of Parental Figures. Each subject imagined first his mother and then his father. Questions were asked about size, look, and spatial and emotional distance of the imagined parent. The patient was then asked to describe the personality of each parent by underlining at least 20 of 85 adjectives in a list called Family Climate Scale. This originally consisted of four factors, Closeness, Spontaneity, Distance, and Chaos, but the two administered were Factor I (positive traits) and Factor II (negative traits). Emotional distance correlated positively with Factor I and negatively with Factor II. For the maternal figure there was a correlation with distance in metres and Factor I scores. The Inner Images of Parental Figures may be a valuable complement in psychotherapy, mapping out emotional relations between patients and their parents. © Perceptual and Motor Skills 2006.

    Graphometric variables of one's signature: I. Basic measures2007In: Perceptual and Motor Skills, ISSN 0031-5125, E-ISSN 1558-688X, Vol. 105, no 3 I, p. 733-752Article in journal (Refereed)
    Abstract [en]

    This study focused on statistical properties and interrelationships of graphometric variables of the signatures of outpatients, 100 men and 119 women, remitted from somatic and psychiatric clinics for possible psychotherapy or for tests of IQ, personality, or brain lesions. The patients' signature on test forms were used. The type of handwriting was classified into Common, Print and Block letters, quantified in breadth, length, and area and grades of slant of minuscules ("lower-case letters") and majuscules ("upper- case"). Analysis indicated sex and age played roles in style of handwriting and size of letters, writing styles differed on most graphometric variables, and meaningful patterns of interrelationships among graphometric variables were specified by factor analysis. © Perceptual and Motor Skills 2007.

    Graphometric variables of one's signature: II. Correlations with measures of perception, cognitive function, and personality2008In: Perceptual and Motor Skills, ISSN 0031-5125, E-ISSN 1558-688X, Vol. 107, no 1, p. 197-221Article in journal (Refereed)
    Abstract [en]

    This study focused on interrelations between graphometric variables of the signature and measures of perception, cognitive function, and personality. Signatures from a sample of psychiatric and somatic outpatients (N=205) were analyzed into 23 graphometric variables and correlated with tests of IQ, cognitive and perceptual function, and personality. The results of a factor analysis of the graphometric, perceptual, and cognitive variables were very much like results from previous studies. Relationships with the graphometric variables can be described in five categories of intelligence, psychomotility, flexibility and speed of closure, and personality. Graphometric signs of Extraversion and Neuroticism were identified, and the two capitals in the signature indicated different psychological meanings. Measurements of the signature offered important personality information. © Perceptual and Motor Skills 2008.
