“…It is interesting that the recent study by Eells (1961) which compared the subsequent emotionality of different groups (gentled, mistreated, inconsistently treated, nonstimulated) produced findings that are partially supportive of the position of Levine and Denenberg and partially supportive of ours. Consistent with the former position is the finding that the emotionality of the nonstimulated group was higher than any of the other groups.…”

Each of 4 strains of inbred mice was divided into an experimental group, exposed to noxious, infantile stimulation, and a control group. Effects of treatment were assessed at 30 days by an open-field measure of emotionality and motility, at 70 days by a stovepipe measure of timidity, and at 100 days by the open-field measure. Significant strain differences were observed in all measures; experimental Ss were more emotional and less motile at 30 days and more timid at 70 days than control Ss. 3 of 5 tests for interaction between genetic (strain) and ontogenetic (infantile treatment) factors were significant. These results are unambiguous concerning the importance of genotype and infantile trauma as determinants of mouse temperament.

“…Apart from this, it is difficult to reach any more definite conclusion regarding the "agreeableness" of gentle handling, or its "desirability." From the available reports, perhaps one of the effects of previous handling is that handled animals exhibit a decrease in fear, irrespective of the handling being gentle or comparatively rough (Eells, 1961;Spence & Maher, 1962a, 1962b. On the other hand, our results confirm previous findings that handling, and particularly handling by the tail, has aversive characteristics, even if this handling is executed manually and as gently as possible (Black, Fowler, & Kimbrell, 1964;Eikelboom, 1986;Fowler, 1963;McAllister, McAllister, Hampton, & Scoles, 1980;Rigter et al, 1980;Wong, 1972).…”

“…The third measure was baseline corticosterone concentration, which can be reduced by EH (Plotsky & Meaney, 1993, but see Macri et al, 2004). Finally, we used a human interaction test because EH rats struggle, squeak, and defecate less during handling than NH ones (Eells, 1961;Ferré et al, 1995). We measured handleability, but also a novel physiological response to handling: the Harderian gland secretion, chromodacryorrhoea (''red/bloody tears'') (e.g., Clement, 1994;Harkness & Ridgway, 1980;Mason, Wilson, Hampton, & Wurbel, 2004).…”

Marked for life? Effects of early cage‐cleaning frequency, delivery batch, and identification tail‐marking on rat anxiety profiles

Daily handling of preweanling rats reduces their adult anxiety. Even routine cage-cleaning, involving handling, reduces adult anxiety compared with controls. Cage-cleaning regimes differ between animal breeders, potentially affecting rodent anxiety and experimental results. Here, 92 adult male rats given different cage-cleaning rates as pups, were compared on plus-maze, hyponeophagia, corticosterone, and handling tests. They were pair-housed and half were tailmarked for identification. Anxiety/stress profiles were unaffected by cage-cleaning frequency, suggesting that commercial-typical differences in husbandry contribute little variance to adult rat behavior. However, delivery batch affected some elevated plus-maze measures. Also, tail-marked rats spent three times longer on the plusmaze open arms than their unmarked cagemates, suggesting reduced anxiety, yet paradoxically they showed greater chromodacryorrhoea responses to handling, implying increased aversion to human contact. A follow-up study showed that rats avoided the odor released from the marker pen used. Thus, apparently trivial aspects of procedure can greatly affect experimental results.
