Genetic and adoptive motherhood: Stress,marital relationship,and child care support

In this paper we characterize adoptive and genetic motherhood with or without stress indicators. Participants were 86 mothers (36 adoptive, 50 genetic) with children from 0 to 12 years old. They answered questions about focal child and mother profile, marital relationship, child care support and the Lipp's Stress Symptoms Inventory for Adults. Results showed that mothers in both groups reported child care support, but there was more participation of nonrelatives in the care of adoptive children and relatives in the care of genetic children. There was greater marital stability and less conflict with the arrival of the child in the adoptive families and predominance of stress indicators in genetic mothers. We concluded that, although there are differences between adoptive and genetic motherhood, these do not imply advantages for one versus the other. Moreover, marital stability related to the adoption process and sociodemographic characteristics of adoptive mothers may have contributed to lower prevalence of stress.     

Does young adults’ preferred role in decision making about health,money, and career depend on their advisors’ leadership skills?

Few empirical data exist on how decision making about health differs from that in other crucial life domains with less threatening consequences. To shed light on this issue we conducted a study with 175 young adults (average age 19 years). We presented the participants with scenarios involving advisors who provided assistance in making decisions about health, money, and career. For each scenario, participants were asked to what extent they wanted the advisor to exhibit several leadership styles and competencies and what role (active, collaborative, or passive) they preferred to play when making decisions. Results show that decision making about health is distinct from that in the other domains in three ways. First, most of the participants preferred to delegate decision making about their health to their physician, whereas they were willing to collaborate or play an active role in decision making about their career or money. Second, the competencies and leadership style preferred for the physician differed substantially from those desired for advisors in the other two domains: Participants expected physicians to show more transformational leadership—the style that is most effective in a wide range of environments—than those who provide advice about financial investments or career. Finally, participants’ willingness to share medical decision making with their physician was tied to how strongly they preferred that the physician shows an effective leadership style. In contrast, motivation to participate in decision making in the other domains was not related to preferences regarding advisors’ leadership style or competencies. Our results have implications for medical practice as they suggest that physicians are expected to have superior leadership skills compared to those who provide assistance in other important areas of life.     

‘Lyin' Ted’, ‘Crooked Hillary’, and ‘Deceptive Donald’: Language of Lies in the 2016 US Presidential Debates

Language in the high‐stakes 2016 US presidential primary campaign was contentious, filled with name‐calling, personal attacks, and insults. Language in debates served at least three political functions: for image making, to imagine potential realities currently not in practice, and to disavow facts. In past research, the reality monitoring (RM) framework has discriminated accurately between truthful and deceptive accounts (~70% classification). Truthful accounts show greater sensory, time and space, and affective information, with little evidence of cognitive operations. An RM algorithm was used with Linguistic Inquiry and Word Count software to code candidates' language. RM scores were significantly higher in fact‐checked truth statements than in lies, and debate language in the 2016 primaries was as deceptive as fact‐checked lies. In a binary logistic regression model, one RM criterion, cognitive processes, predicted veracity using computerized RM, classifying 87% of fact‐checked truth statements but only 28% of fact‐checked lie statements (63% classification overall).Copyright © 2017 John Wiley & Sons, Ltd.     

Symmetry brings an impression of familiarity but does not improve recognition memory

Studies have shown that symmetric stimuli are recognized better than asymmetric stimuli but evidence suggests that this advantage may result from a familiarity bias induced by symmetry. We used a classic episodic memory paradigm to test this bias and see if it truly accounts for the symmetry advantage. Subjects first encoded symmetric and asymmetric figures. During a subsequent recognition phase, they discriminated the encoded (old) figures from new intermixed figures. The recognition rate of old figures was higher with symmetric figures than asymmetric figures. However, the tendency to falsely recognize new figures was also higher when they were symmetric, meaning that the higher recognition rate for symmetric figures was artificially inflated by a response bias. Three other experiments further tested this finding and examined the influence of some variables (rotation in virtual 3D space, stimulus meaningfulness, and redundancy of information) on the bias. A fifth experiment with photo stimuli confirmed that the response bias also applies to objects that we regularly encounter in everyday life. In conclusion, our results show that symmetry does not enhance mnemonic processes but instead induces a response bias leading individuals to judge such stimuli as having been seen.     

Functional magnetic resonance imaging study of Piaget's conservation-of-number task in preschool and school-age children: a neo-Piagetian approach

Jean Piaget’s theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children’s thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget’s conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age.     

Visual memory and visual perception: when memory improves visual search

This study examined the relationship between memory and perception in order to identify the influence of a memory dimension in perceptual processing. Our aim was to determine whether the variation of typical size between items (i.e., the size in real life) affects visual search. In two experiments, the congruency between typical size difference and perceptual size difference was manipulated in a visual search task. We observed that congruency between the typical and perceptual size differences decreased reaction times in the visual search (Exp. 1), and noncongruency between these two differences increased reaction times in the visual search (Exp. 2). We argue that these results highlight that memory and perception share some resources and reveal the intervention of typical size difference on the computation of the perceptual size difference.     

Memory for events and locations obtained in the context of elicited imitation: evidence for differential retention in the second year of life

Previous research has suggested that infants may have more robust memory for past experiences relative to memory for locations that have been encountered previously. This assertion, however, primarily results from the comparison of data that were collected using different experimental procedures. In the present study, we examined memory for events and memory for locations in the context of elicited imitation. Specifically, 13-, 16-, and 20-month-old infants were tested for long-term memory for events and locations after between-subjects delays of 1, 3, 6, 9, and 12 months. The results indicated that the event memory was retained over lengthier delays relative to the location memory, despite superior encoding of location information. The possible adaptive significance of long-term memory for events ontogenetically preceding long-term memory for locations is discussed.     

The influence of contour fragmentation on recognition memory: an event-related potential study

The present study was carried out to examine how the event-related potentials to fragmentation predict recognition success. Stimuli were abstract meaningless figures that were either complete or fragmented to various extents but still recoverable. Stimuli were first encoded as part of a symmetry discrimination task. In a subsequent recognition phase, encoded stimuli were presented complete along with never presented stimuli and participants performed an old/new discrimination task. Fragmentation stimuli elicited more negative ERPs than complete figures over the frontal, central and parietal areas between 180 and 260 ms, and over the occipito-temporal areas between 220 and 340 ms. Only this latter effect was modulated as a function of whether stimuli were recognized or not during the recognition phase of the memory test. More specifically, the effect occurred for stimuli that were later forgotten and was absent for stimuli that were later recognized. This ERP to fragmentation, the occipito-temporal N(frag), possibly reflects the brain response to encoding difficulty, and is thus predictive of recognition performance.     

An fMRI investigation of a novel analogue to the Trail-Making Test

The Trail-Making Test (TMT) is a widely used neuropsychological measure that assesses visuomotor abilities and cognitive flexibility. For the TMT-A condition participants are required to locate and connect numbers (i.e. 1-2-3…) while in the TMT-B condition participants perform the set-shifting task of locating and connecting numbers and letters (i.e. 1-A-2-B…). The TMT-B condition has shown impairments in many clinical populations, particularly schizophrenia patients, but the neurobiological underpinning of the task can be difficult to discern given pragmatic obstacles in adapting the task for neuroimaging. In a behavioural testing experiment we demonstrated a close correspondence between performance on the standard TMT and a novel, computer programmed adaptation of the TMT (pcTMT). The pcTMT was designed for functional magnetic resonance imaging (fMRI) administration and neuroimaging data for this task were obtained in. A whole brain analysis revealed significantly greater activation during the pcTMT-B relative to the pcTMT-A in right inferior/middle frontal cortices, right precentral gyrus, left angular gyrus/left middle temporal gyrus. These results identify the regions that most likely underlie cognitive flexibility during the TMT and are candidate regions underlying the impairment of groups with poor set-shifting abilities.     

��What I wanted to do was���� Discrepancies Between College Women��s Desired and Reported Responses to Gender Prejudice

When experiencing gender prejudice, college women engage in a dynamic decision making process about whether and how to respond. We examined the discrepancy between how college women wanted to respond and how they actually responded to gender prejudice events and explored their reasons for not using a desired response. In this study, 81 college women from the Western United States responded to a qualitative online daily diary about gender prejudice. In 34% (N?=?265) of the events, the women reported there was a discrepancy between what they wanted to do and how they actually reacted, with the most common discrepancy being a desire to utilize a confrontational response (91%, N?=?242). Over the two week period, women reported significantly more events during which they considered the use of a confrontational response (N?=?242) than they actually used one (N?=?199). Women??s reported reasons for not using their desired response included: not being cost effective (25%), concern about social norms (37%), setting limitations (19%), personality characteristics (9%) and not being bothered enough by the event (10%). We also found that when women considered using a confrontational response but decided not to, they reported using all other response types instead. In these cases, women who did nothing during the event reported lower levels of distress during the event than women who used a psychological response or a different confrontational response. Implications and future research directions are discussed.
