The influence of one memory retrieval on a subsequent memory retrieval

Abstract: Ss produced an instance of a category and following zero or two intervening items produced a second instance of the same category. The second instance was produced more quickly than the initial instance. This finding, in conjunction with other data reported in the paper, indicate that the reduction in latency for the second instance is due mostly to a reduction in the rate with which the category is searched.

A linear relationship between H‐reflex latency and sensory conduction velocity in diabetic neuropathy

Abstract: This study shows that there is a linear relationship between H-reflex latency and sensory conduction velocity in diabetic patients. Because the H-reflex latency is more easily determined than the sensory conduction velocity, H-reflex latency may be of use in assessing the neuropathy of diabetes.

Herpes virus latency in spinal ganglia of mice without illness.

Abstract: Summary Mice that remained free of illness after infection with herpes virus had latent virus in spinal ganglia on the side ipsilateral, but not contralateral to the limb inoculated for 14-99 days. The data demonstrate that induction of latency in neuronal cells is an efficient process which can occur independently of appreciable clinical manifestations.

The Relationship between Speed of Performance and Conceptual Style: The Effect of Imposed Modification of Response Latency

Abstract: ZELNIKER, TAMAR; COCHAVI, DALu; and YERED, JOSHUA. The Relationship between Speed of Performance and Conceptual Style: The Effect of Imposed Modification of Response Latency. CmLD DEVELOPMENT, 1974, 45, 779-784. The relationship between speed of performance and conceptual style was examined by imposing short and long response latencies on analytic and nonanalytic second-grade subjects, respectively. It was predicted that with these response latency manipulations, analytic children would decrease and nonanalytic children would increase their production of analytic responses. The expected change was obtained only for nonanalytic children.

A model for masking rotational latency by dynamic disk allocation

Abstract: This paper presents the background and algorithms for masking the rotational latency of a disk or drum. It discusses the anticipatory input and output of blocks of data to buffer and primary memories for a mono-programmed computer system. A basic permutation algorithm and several variations are given. Because of the anticipatory nature of the I/O scheduling, these algorithms are restricted to classes of programs with predictable behavior. While the methods are not restricted to numerical computations, matrix and partial differential equation methods are typical examples of their use. It is shown that latency may be masked using a small amount of buffer memory. The methods discussed are independent of the overall size of the data base being considered.

Latency and frequency of responding under discrete-trial fixed-interval schedules of reinforcement.

Abstract: Pigeons' key pecking was studied under a number of discrete-trial fixed-interval schedules of food reinforcement. Discrete trials were presented by briefly illuminating the keylight repetitively throughout the interreinforcement interval. A response latency counterpart to the fixed-interval scallop was found, latency showing a gradual, negatively accelerated decrease across the interval. This latency pattern was largely invariant across changes in fixed-interval length, number of trials per interval, and maximum trial duration. Frequency of responding during early trials in the intervals varied, however, with different schedule parameters, being directly related to fixed-interval length, inversely related to number of trials, and complexly affected by conjoint variations of fixed-interval length and number of trials. Response latency thus was found to be simply related to elapsed time during the interval while response frequency was complexly determined by other factors as well.

The effect of photic stimulation on the latency of the first epileptic discharge in rats under hyperbaric conditions.

Abstract: Age of African pike Hepsetus odoe from Ado Ekiti Reservoir Ekiti State, Nigeria was studied. Annuli on the opercula bones and scales were used to determine the age. The standard length of specimens examined varied between 12.50 and 29.80 cm and body weight 10-385 g. Annuli (growth rings) observed on the opercula bones of specimens with mean standard lengths 21.70±1.4 cm had one real annulus, 24.80±1.1 cm had two real annuli, 27.4±0.9cm had three real annuli indicating age one, two, and three (1(superscript +), 2(superscript +), 3(superscript +)) respectively. Growth rings observed on scales appeared as interruptions in the normal patterns of scales. Specimens with mean standard lengths of 21.3±1.5 cm, 24.7±0.8 cm and 27.35±11 cm were interpreted to be ages 1(superscript +), 2(superscript +), and 3(superscript +) respectively. The maximum age of samples, derived from annuli on both opercula bones and scales was 3 years. Specimens below 18 cm standard length did not register any growth mark. The mean lengths at the estimated ages obtained using both opercula bones and scales were not significantly different (P＞0.05, P＞0.01).
