Three-Year-Old Children Detect Social Exclusion in Third-Party Interactions

Humans are motivated to connect with others and are sensitive to social exclusion—intentionally leaving out others. This ability to detect social exclusion is suggested to be evolutionarily adaptive, biologically hardwired, and an important feature of social-cognitive development. Yet it is unclear when children start to independently detect social exclusion. Previous developmental research on social exclusion has focused on children older than 4 years of age, but recent infancy research has suggested younger children may be able to process complex social interactions such as social exclusion. The present study is the first to examine whether 2- to 3-year-old children detect social exclusion and if they prefer to affiliate with individuals who have been excluded over individuals who exclude others. Across 2 experiments, 2- and 3-year-old children (N = 140) viewed exclusive group interactions, in which 2 agents unjustly excluded 1 agent, and children were asked to choose whether they preferred to play with an excluded agent or an exclusive agent. Three-year-old children consistently preferred to play with the excluded agent, whereas 2-year-old children showed no preference. Three-year-old children did not show a preference among agents engaged in inclusive interactions and did not prefer an agent who refused to engage with a group, showing that 3-year-old children distinguish unjust exclusion from other types of interactions. Together, these findings suggest 3-year-old children detect social exclusion and are motivated to affiliate with unjustly excluded agents over those who exclude others, whereas these capacities are still developing in 2-year-old children.     

Perceiving a calling and well-being: Motivation and access to opportunity as moderators

The current study examined moderator variables that may accentuate the effect of perceiving a calling on well-being amongst a large and diverse sample of working adults (N = 746). Drawing from Self Determination Theory (SDT; Deci & Ryan, 2000) and the Psychology of Working Theory (PWT: Duffy, Blustein, Diemer, & Autin, 2016), perceiving a calling was hypothesized to have greater effects on wellbeing for individuals with greater calling motivation and access to vocational opportunity, as assessed by income and work volition. Three moderated, multiple mediator models using structural equation modeling were run to test these hypotheses. Specifically, life meaning and living a calling were positioned as mediator variables in the relation of perceiving a calling to life satisfaction and the paths from perceiving a calling to the mediators were proposed to be significantly moderated. Calling motivation was found to be a significant moderator for both paths, supporting propositions of SDT. As the motivation to pursue one's calling increased, the direct effects on life meaning and living a calling and the indirect effects on life satisfaction were stronger. Income was also found to be a significant moderator, supporting propositions of the PWT, but only in the relation of perceiving a calling to living a calling. It was proposed that work volition—a variable related to the perception of vocational opportunity—may be better positioned as correlate of calling variables versus a moderator variable affecting the impact of having a calling. Practical implications are discussed.     

Effects of pharmacological manipulations of NMDA-receptors on deliberation in the Multiple-T task

Both humans and non-human animals have the ability to navigate and make decisions within complex environments. This ability is largely dependent upon learning and memory processes, many of which are known to depend on NMDA-sensitive receptors. When humans come to difficult decisions they often pause to deliberate over their choices. Similarly, rats pause at difficult choice points. This behavior, known as vicarious trial and error (VTE), is hippocampally dependent and entails neurophysiological representations of expectations of future outcomes in hippocampus and downstream structures. In order to determine the dependence of VTE behaviors on NMDA-sensitive receptors, we tested rats on a Multiple-T choice task with a reward-delivery reversal known to elicit VTE. Rats under the influence of NMDA-receptor antagonists (CPP) showed a significant reduction in VTE, particularly at the reward reversal, implying a role for NMDA-sensitive receptors in the generation of vicarious trial and error behaviors.

Testing the latent factor structure and construct validity of the Ten-Item Personality Inventory

Recent efforts have aimed to develop relatively short measures of the Five-Factor Model (FFM) of personality, particularly for when time and/or space is limited. We evaluate the Ten-Item Personality Inventory (TIPI), a non-proprietary FFM measure with two items per dimension. We use a latent variable methodology to examine the TIPI’s factor structure and convergent validity with the 50-item International Personality Item Pool (IPIP) FFM measure. We provide correlations between the scale scores and latent factors, and compare each measure’s pattern of correlations with measures of other individual difference constructs. Results were favorable in terms of the factor structure and convergent validity of the TIPI, particularly regarding the correlations between the respective latent factors of the TIPI and the IPIP–FFM measures.     

Role of pituitary-adrenocortical system in mediating avoidance behavior of rats with septal lesions.

Three experiments examined the hypothesis that the effects of septal lesions and systemic injections of scopolamine on avoidance acquisition could be attributed to the effects of either of these treatments on adrenocorticotropic hormone (ACTH) secretion. Septal lesions and scopolamine facilitated 2-way conditioned avoidance response acquisition, and the lesions retarded passive avoidance acquisition. However, neither the injections of dexamethasone, a synthetic glucocorticoid which inhibited ACTH secretion as did septal lesions, nor injections of ACTH which mimicked the facilitatory effects of scopolamine on basal ACTH secretion, affected avoidance in these paradigms. Thus, the main hypothesis was not supported. The finding that scopolamine did not affect passive avoidance indicates that a cholinergic system may not be involved in mediating the suppressive effects of punishment.
