Visual Short Term Memory

Visual short-term memory was tested in a delayed-discrimination task on rhesus monkeys before and after a systemic injection of the antioxidant oxymetacil (4 – 7 mg kg−1). Monkeys had to discriminate stimuli with different visual attributes (colour, orientation, spatial frequency, size, contrast, spatial relationships between visual objects) by a delayed (0 – 32 s) instrumental reflex. Oxymetacil had no influence upon visual discrimination without delay, but after injection of this drug the delayed discrimination (associated with mechanisms of short-term memory) of different stimuli was significantly improved. Oxymetacil increased the duration of short-term storage of spatial information by a factor of 2 – 4 and decreased motor reaction time. Application of oxymetacil in the same doses produced similar results for delayed discrimination of black-and-white gratings, or geometrical figures of different orientations and size. The duration of short-term information storage was doubled or trebled and the motor reaction time was decreased. If monkeys were required to discriminate colour figures, the duration of short-term information storage was also doubled, being longer than for any of the other tasks. The results are discussed in terms of effects on cortical interregional synchronisation mechanisms responsible for control processes such as attention.

Short Term Exposure

Abstract This study investigated the effect of short-term exposure to Wi-Fi signals on the cognitive functions of the mind. After obtaining permission from the local Ethics Committee of Shiraz University of Medical Sciences and approval by the Iranian Registry of Clinical Trials (IRCT2017041233398N1), 45 male and female students from Shiraz University of Medical Sciences volunteered to participate in this study. They were exposed to Wi-Fi signals in two sham and exposure sessions, each for 2 hours. After completion, they took part in reaction time, short-term memory, and reasoning ability tests. After scoring, the data were analysed by SPSS software. In addition, the electric field strength and power density were calculated. The results showed no statistically significant differences between the mean scores of reaction time, short-term memory, and reasoning ability in sham and exposure. Also, the obtained values from the electric field strength and power density (E = 4.1 Vm−1, P = 0.446 Wm−2) were lower than that of threshold values by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Our results can greatly reduce concerns regarding the effects of short-term exposure to Wi-Fi waves on cognitive functions.

Alternative Hypotheses

Recognition memory for sub-span digit sequences was investigated using Stern-berg's varied-set RT technique. Two experiments studied memory for sequences containing repetitions (e.g. 9 1 9 3) and observed faster recognition of repeated items. Experiment I also showed serial position effects with faster responding to more recent items. Neither of these effects is predicted by Sternberg's highspeed exhaustive scanning hypothesis. Several alternative hypotheses are considered, including two models based on the concept of trace strength, which appear to merit further investigation.

Dual Task Performance

Four tasks were tested in single and pairwise combined performances to investigate their mutual interference. The results demonstrate that functionally dissimilar tasks, in terms of the activities required in processing and responding, can be performed together with much less decrement than functionally identical tasks. The short-term memory function, furthermore, is extremely disruptive when required in one or both of two simultaneously performed discrete, reaction-time tasks.
