Children exhibit neotenous, or physically immature, features, such as a large rounded head relative to body size, adult-sized eyes, round cheeks, a small chin, and a short narrow nose. Bowlby (1969) and others (Eibl-Eibesfeldt, 1989; Hrdy, 2005) propose that, in species whose young depend on care from an adult, these features could enhance offspring survival. Lorenz (1943) argued that adult humans are particularly attracted to these features, and that these characteristics, which he termed...

Bowlby (1969) and others (Eibl-Eibesfeldt, 1989; Hrdy, 2005) propose that, in species whose young depend on care from an adult, these features could enhance offspring survival. Lorenz (1943) argued that adult humans are particularly attracted to these features, and that these characteristics, which he termed Kindchenschema or “baby schema,” trigger a cognitive system that processes and reacts specifically to infantile features for the purpose of enhancing motivation to engage in caretaking behaviors. The goal of the studies proposed here is to examine the behavioral, attentional, and emotional effects of baby schema.

- Abstract/Description

Experimentally naive rats show variance in their locomotor reactivity to novelty, some displaying higher (HR) while others displaying lower (LR) reactivity, associated with vulnerability to stress. LRHR phenotype is proposed as an antecedent to the development of stress hyper responsiveness. Results presented here show emergence of antidepressive-like behavior following peripubertal-juvenile exposure to chronic variable physical (CVP) and chronic variable social stress (CVS) in HR rats, and...
Show moreExperimentally naive rats show variance in their locomotor reactivity to novelty, some displaying higher (HR) while others displaying lower (LR) reactivity, associated with vulnerability to stress. LRHR phenotype is proposed as an antecedent to the development of stress hyper responsiveness. Results presented here show emergence of antidepressive-like behavior following peripubertal-juvenile exposure to chronic variable physical (CVP) and chronic variable social stress (CVS) in HR rats, and depressive-like behavior following CVP in the LRs. The antidepressive-like behavior in HR rats was accompanied by increased levels of acetylated Histone3 (acH3) and acetylated Histone4 (acH4) at the hippocampal brain-derived neurotrophic factor (BDNF) P2 and P4 promoters respectively. This effect may mediate increased mossy fibre (MF) terminal field size, particularly the suprapyramidal mossy fibre projection volume (SP-MF), in the HR animals following both stress regimens. These findings show that chronic variable stress during adolescence induces individual differences in molecular, neuromorphological and behavioral parameters between LRs and HRs, which provides further evidence that individual differences in stress responsiveness is an important factor in resistance or vulnerability to stress-induced depression and/or anxiety.
