  Title Within-species variation in the development of ultrasonic signaling of preweanling rats Type Journal Article
  Year 1979 Publication Developmental Psychobiology Abbreviated Journal Dev Psychobiol  
  Volume 12 Issue 2 Pages 129-136  
  Keywords Animals; *Animals, Newborn; Animals, Suckling; Body Weight; Cold/adverse effects; Environment; Genotype; Individuality; Object Attachment; Rats; Stress/*physiopathology; Ultrasonics; *Vocalization, Animal  
  Abstract The development of litter and individual differences in the rate of ultrasonic signaling of neonatal rats was studied. Systematic variations among litters and individuals emerged, without differential treatment. These differences were not correlated with variations in general development as indexed by body weight. Two experiments using a cross-fostering design showed that litter differences developed independently of variations in postnatal environment. These results indicate that the variations among litters in ultrasound rate have a prenatal, possibly genetic, etiology and may represent reliable indicants of response to environmental stress.

  Title Discrimination reversal learning in yearling horses Type Journal Article
  Year 1979 Publication J. Anim. Sci. Abbreviated Journal J. Anim. Sci.  
  Volume 49 Issue 2 Pages 583-588  
  Keywords  
  Abstract Twenty-six yearling horses were tested on a serial reversal learning discrimination combining spatial and brightness cues. An original discrimination of rewarded or nonrewarded stimuli was made followed by 20 daily reversals for position/brightness discrimination. Learning criteria were defined as 11 out of 12 correct, with the last eight responses all correct. Each horse was allowed 30 trials per discrimination to achieve criteria. Mean errors (ME) and mean trials (MT) required to achieve criteria were computed for each horse. A relative learning ability index (LAI) was calculated by the formula 1000/MT/ME. A daily emotionality score, based on a scale of one (tranquil) to six (very excitable) was assigned each horse each day after testing and a mean computed for each horse. A single subjective trainability score, based on a scale of one (difficult to train) to six (easy to train) was obtained for each horse from an independent trainer. Linear regression analyses for all 26 horses revealed a reduction in MT and ME (P<.01) over the 21-day test period indicating evidence of learning to learn. Differences (P<.05) were evident between sexes for MT and ME. Significant correlations between trainability scores and learning ability indices MT, ME, and LAI were evident for colts and geldings but not for fillies. Pooled data showed significant correlations between ME and trainability. There was a negative correlation (P<.05) between emotionality and trainability scores for all 26 horses, although the filly group did not exhibit significant correlation between these parameters.
