Retrograde Amnesia after ECT. An Attempt to Demonstrate Reminder-effects in Humans

In a study of the retrograde amnesic effect of bilateral ECT, twelve patients were subjects in a repeated measures design. Both verbal and nonverbal materials were used and retention was tested with different methods: Yes-no recognition, forced-choice recognition and recall cued by initial letters. The absolute amount of retrograde amnesia was small; there seemed to be no difference between verbal and nonverbal materials, and cueing with initial letters was not found to be an effective method of reducing amnesia.     

Fading—A new technique in the treatment of phobias

Phobias have been subject to more research by behavior therapists than any other psychiatric disorder. In 1975 Marks described more than 20 different techniques that have been developed for or used in the treatment of phobias.The technique to be described in this paper—fading—was first used by Barlow and Agras (1973) as an alternative to aversive techniques for homosexuals. Originally the technique was designed to change the stimulus control of sexual responsiveness by introducing or “fading in” heterosexual stimuli during periods of sexual arousal elicted by homosexual stimuli.One purpose of the single-case studies presented here was to explore the possibility of achieving a similar result with phobic clients. In other words, the aim was to create a state of calmness and positive sensations in the client and then to gradually “fade in” phobic stimuli. The hypothesis was that the stimulus control of anxiety exerted by the phobic stimuli would decrease and finally be extinguished due to the antagonistic effects of observing and imagining positive scenes.A second purpose of this application of fading was to develop a technique for reducing phobic anxiety which could give more control to the client than is the case in, for example, systematic desensitization.     

An information processing analysis of mental multiplication

The specific model of central or conscious processing system (CPS) is presented. It consists of two part: (1) a number of information carrying registers, and (2) a functional unit controlling the processes performed on the contents of the registers. The capacity limit is explained as a combination of storage capacity and processing capacity. The capacity limit was estimated by an experiment using mental multiplication performed according to a particular algorithm. The results suggested that the capacity was around eight to nine registers when the algorithm was strictly followed; this limit could, however, be exceeded because some problems automatically were coded and remembered by rules rather then by rehearsal. The results further suggested that information processing, i.e. the multiplication, had to take place on a time-sharing basis in competition with rehearsal, thus suggesting the existence of higher-order control system.     

The usefulness of assessing suggestibility and compliance in prisoners with unidentified intellectual disabilities

Søndenaa, E., Rasmussen, K., Palmstierna, T. & Nøttestad, J. A. (2010). The usefulness of assessing suggestibility and compliance in prisoners with unidentified intellectual disabilities. Scandinavian Journal of Psychology, 51, 434–438. This present study explored the relationship of interrogative suggestibility (n = 133) and compliance (n = 118) to intellectual functioning among prison inmates. The Norwegian versions of the Gudjonsson Suggestibility Scale (GSS) and the Gudjonsson Compliance Scale (GCS) were used. The results supported previous findings of a negative correlation between the Gudjonsson scales and IQ, and the scales were found useful throughout the IQ range. The impact of a memory artifact was discussed in the light of recent studies and criticism of the scales.     

Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates

Hintsanen, M., Alatupa, S., Pullmann, H., Hirstiö‐Snellman, P. & Keltikangas‐Järvinen, L. (2010). Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates. Scandinavian Journal of Psychology 51, 488–494. The present study examined the validity of self‐ and teacher‐reported social status and its relations to self‐esteem and temperament in a geographically representative cohort of Finnish adolescents (N = 3941, mean age 15.1 years). High agreement was found between self‐ and teacher‐rated social status (r = 0.42). Different aspects of self‐esteem were differently related to social status. When other temperament and self‐esteem variables were included in the analyses, strongest predictor for self‐rated social status in both genders was social self‐esteem (p < 0.01) and for teacher‐rated social status general self‐esteem (p < 0.01). The strongest temperamental predictors of social status were lower inhibition in girls (p < 0.01, self‐ and teacher‐rated) and higher impulsivity (p < 0.01, self‐rated) and activity (p < 0.01, teacher‐rated) in boys. The present findings are consistent with the view that social functioning and peer relations are associated with individual differences in self‐concept and temperament dimensions.
