Differential effects of makeup on perceived age

Makeup accentuates three youth‐related visual features – skin homogeneity, facial contrast, and facial feature size. By manipulating these visual features, makeup should make faces appear younger. We tested this hypothesis in an experiment in which participants estimated the age of carefully controlled photographs of faces with and without makeup. We found that 40‐ and especially 50‐year‐old women did appear significantly younger when wearing makeup. Contrary to our hypothesis, 30‐year‐old women looked no different in age with or without makeup, while 20‐year‐old women looked older with makeup. Two further studies replicated these results, finding that makeup made middle‐aged women look younger, but made young women look older. Seeking to better understand why makeup makes young women look older, we ran a final study and found evidence that people associate makeup use with adulthood. By activating associations with adulthood, makeup may provide an upward bias on age estimations of women who are not clearly adult. We propose that makeup affects social perceptions through bottom‐up routes, by modifying visual cues such as facial contrast, facial feature size, and skin homogeneity, and also through top‐down routes, by activating social representations and norms associated with makeup use.     

Role of muscarinic M1 receptors in inhibitory avoidance and contextual fear conditioning

The objective of the present study was to observe the effects of pre-training or post-training administration of dicyclomine, a M1 muscarinic antagonist, on inhibitory avoidance (IA) and contextual fear conditioning (CFC) and to investigate if the effects observed with the pre-training administration of dicyclomine are state-dependent. For each behavioral procedure (IA and CFC) groups of Wistar male rats were treated with saline or dicyclomine either 30 min before training (pre-training), immediately after training or 30 min before training/30 min before test (pre-training/pre-test). The animals were tested 24 h after training. The acquisition of IA and CFC was impaired by pre-training administration of dicyclomine. The consolidation of both tasks was not affected by dicyclomine given immediately after training. Pre-training/pre-test administration of dicyclomine impaired both tasks, an effect similar to that observed in the group which only received pre-training administration. Pre-test treatment induced dissociation between both tasks, impairing CFC retrieval, without interfering with the animals avoidance response. These results show that the dicyclomine did not affect IA and CFC consolidation, suggesting specific involvement of M1 muscarinic receptor only in acquisition these tasks, and these effects was not state-dependent. However, it is possible that the retrieval of these tasks may be mediated, at least in part, by different neurochemical mechanisms and may be dissociated by dicyclomine.

Are indigenous personality dimensions culture specific? Philippine inventories and the five-factor model.

The authors addressed the culture specificity of indigenous personality constructs, the generalizability of the 5-factor model (FFM), and the incremental validity of indigenous measures in a collectivistic culture. Filipino college students (N = 508) completed 3 indigenous inventories and the Filipino version of the Revised NEO Personality Inventory (NEO-PI-R). On the basis of the factor and regression analyses, they concluded that (a) most Philippine dimensions are well encompassed by the FFM and thus may not be very culture specific: (b) a few indigenous constructs are less well accounted for by the FFM: these constructs are not unknown in Western cultures, but they may be particularly salient or composed somewhat differently in the Philippines; (c) the structure of the NEO-PI-R FFM replicates well in the Philippines: and (d) Philippine inventories add modest incremental validity beyond the FFM in predicting selected culture-relevant criteria.     

Positive facial affect looks healthy

A healthy appearance is linked to important behavioural outcomes. Here we investigated whether positive facial affect is a cue for perceived health. In study one, two groups of participants rated the perceived health or perceived happiness of a large set of faces with neutral expressions. Perceived happiness predicted perceived health, as did anthropometric measures of expression. In a second experimental study, we collected ratings of perceived health for a wide age range of target faces with either neutral or smiling expressions. Smiling faces were rated as being much healthier looking than neutral faces, confirming that facial expression plays a role in the perception of health. A third study investigating attractiveness as a possible mediator found that expression still had a significant direct effect on perceived health, after accounting for attractiveness. Together, these studies systematically show that facial affect plays a critical role in shaping our perceptions of health in others.     

Classifying and profiling Social Networking Site users: a latent segmentation approach

Social Networking Sites (SNSs) have showed an exponential growth in the last years. The first step for an efficient use of SNSs stems from an understanding of the individuals' behaviors within these sites. In this research, we have obtained a typology of SNS users through a latent segmentation approach, based on the frequency by which users perform different activities within the SNSs, sociodemographic variables, experience in SNSs, and dimensions related to their interaction patterns. Four different segments have been obtained. The "introvert" and "novel" users are the more occasional. They utilize SNSs mainly to communicate with friends, although "introverts" are more passive users. The "versatile" user performs different activities, although occasionally. Finally, the "expert-communicator" performs a greater variety of activities with a higher frequency. They tend to perform some marketing-related activities such as commenting on ads or gathering information about products and brands as well as commenting ads. The companies can take advantage of these segmentation schemes in different ways: first, by tracking and monitoring information interchange between users regarding their products and brands. Second, they should match the SNS users' profiles with their market targets to use SNSs as marketing tools. Finally, for most business, the expert users could be interesting opinion leaders and potential brand influencers.
