The first eye movement from a point of fixation was detected by direct observation of the eye, by electro-oculograph (EOG), and by corneal reflection apparatus. Essential agreement was obtained among the measures. Only with movements less than 5° were there serious numbers of discrepancies in detection against the criterion of photo-recorder corneal reflection measurement. A horizontal movement was detected more reliably than a vertical movement. The EOG was most likely to miss detection of a vertical movement. The efficiency of the measures with regard to movement detection and monitoring choice-looking-behavior were discussed.

This report was initiated to review the techniques and modifications developed by the U.S. Army Aeromedical Research Laboratory for assessing visual performance/workload of pilots during helicopter operations. Although the corneal reflection technique for gathering eye movement data is not new, innovative modifications had to be developed to permit accurate data collection in this flight environment. This study reports on these techniques, modifications, and applications.

Stimulus-driven binocular pursuit and saccadic movements (±4°, ±8°; 0.3 Hz, 0.5 Hz) were measured in 6 cerebral palsied adults and 5 normal adults using a head-free corneal reflection technique. Correlation coefficients for binocular position and r2 were calculated; the latter were pooled for each group into 6 categories of eye movement: horizontal and vertical triangle and sine wave pursuit and saccades. The differences between the group means r2 in each category were tested by the Mann-Whitney U. The eye positions were statistically less conjugate for the cerebral palsy group in all categories. The differences and similarities between the groups are discussed with regard to neural and muscular control, visuomotor development, and organization of the visuomotor system.

Zusammenfassung. Theoretischer Hintergrund: Bei der Behandlung der posttraumatischen Belastungsstörung (PTBS) nach einem Typ-II-Trauma werden im klinischen Alltag gegenwärtig unterschiedliche traumabearbeitende Interventionen eingesetzt. Fragestellung: Wie werden die Verbesserungen in verschiedenen Symptombereichen (plötzliches Wiedererleben, Vermeidung, Übererregung, Dissoziation und zusätzliche Symptomatik) in Abhängigkeit von dem Einsatz unterschiedlicher traumabearbeitender Interventionen von den Behandlern retrospektiv eingeschätzt? Methode: Aus einer Umfrage unter Psychologischen Psychotherapeuten (N = 272) wurden die Fälle ausgewählt, bei denen die Therapeuten (1) ein Ereignis nannten, das einem Typ-II-Trauma zugeordnet werden konnte, und (2) angaben, traumabearbeitende Interventionen gemäß der traumafokussierenden, kognitiven Verhaltenstherapie (TF-KVT), der Methode des Eye Movement Desensitization and Reprocessing (EMDR-Methode) oder der Psychodynamisch-imaginativen Traumatherapie (PITT) durchgeführt zu haben (n = 37). Außerdem beurteilten die Therapeuten retrospektiv die Verbesserungen in den Symptombereichen zu Therapieende. Ergebnisse: Über 40% der Therapeuten gaben an, die Vorstellungsübungen bzw. Bearbeitung des Täter Introjekts gemäß der PITT eingesetzt zu haben, gefolgt von den traumabearbeitenden Interventionen der TF KVT (35.1%) und der EMDR Methode (21.6%). Die Therapeuten, die Interventionen eines der beiden zuletzt genannten Verfahren einsetzten, schätzten die Verbesserungen in den verschiedenen Symptombereichen höher ein als diejenigen, die angaben, eine Intervention gemäß der PITT durchgeführt zu haben. Schlussfolgerungen: Die retrospektiven Einschätzungen der Verbesserungen durch die Therapeuten stehen im Einklang mit den Empfehlungen der Behandlungsleitlinien zur PTBS.

Abstract. We report the results of a meta-analysis of 22 experiments comparing the eye movement data obtained from young ( Mage = 21 years) and old ( Mage = 73 years) readers. The data included six eye movement measures (mean gaze duration, mean fixation duration, total sentence reading time, mean number of fixations, mean number of regressions, and mean length of progressive saccade eye movements). Estimates were obtained of the typified mean difference, d, between the age groups in all six measures. The results showed positive combined effect size estimates in favor of the young adult group (between 0.54 and 3.66 in all measures), although the difference for the mean number of fixations was not significant. Young adults make in a systematic way, shorter gazes, fewer regressions, and shorter saccadic movements during reading than older adults, and they also read faster. The meta-analysis results confirm statistically the most common patterns observed in previous research; therefore, eye movements seem to be a useful tool to measure behavioral changes due to the aging process. Moreover, these results do not allow us to discard either of the two main hypotheses assessed for explaining the observed aging effects, namely neural degenerative problems and the adoption of compensatory strategies.
