Socially Situated Transmission: The Bias to Transmit Negative Information is Moderated by the Social Context

Cultural evolutionary theory has identified a range of cognitive biases that guide human social learning. Naturalistic and experimental studies indicate transmission biases favoring negative and positive information. To address these conflicting findings, the present study takes a socially situated view of information transmission, which predicts that bias expression will depend on the social context. We report a large-scale experiment (N = 425) that manipulated the social context and examined its effect on the transmission of the positive and negative information contained in a narrative text. In each social context, information was progressively lost as it was transmitted from person to person, but negative information survived better than positive information, supporting a negative transmission bias. Importantly, the negative transmission bias was moderated by the social context: Higher social connectivity weakened the bias to transmit negative information, supporting a socially situated account of information transmission. Our findings indicate that our evolved cognitive preferences can be moderated by our social goals.

Collaborative competence,social capital,and mental health: A cross‐sectional analysis of a community‐based intervention for older adults

Social capital interventions for the mental health of older adults have been inconclusive to date, and have rarely investigated the psychological resources that are important to having social capital. This study focused on the “Neighborhoods in Solidarity” (NS), which are a series of Swiss community‐based interventions that aim to empower older adults to participate in their communities. Our goal was to understand whether the NS were associated with collaborative competence, social capital, and subsequently, symptoms of depression. Cross‐sectional data were collected from 947 individuals aged 55 and over (M_age = 68.66, SD = 9.04) in 10 Swiss neighbourhoods (five with the NS [n = 479] and five control neighbourhoods [n = 468]). Structural equation modelling was used to model the relationship between the NS intervention, collaborative competence, cognitive and structural dimensions of social capital, and symptoms of depression (measured by the CESD‐R‐10). Individual participation in the NS had total and indirect effects on symptoms of depression via collaborative competence and both social capitals. These findings suggest that existing community‐based interventions can be indirectly associated with better mental health outcomes in the ageing population.     

Examining children's ability to delay reward: Is the delay discounting task a suitable measure?

Discounting the value of delayed rewards has primarily been measured in children with the delay of gratification task and in adolescents and adults with the delay discounting task. In the present study, we assessed the suitability of the delay discounting task as a measure of temporal discounting in children. A sample of 7- to 9-year-olds (N = 98) completed a delay discounting task, a delay of gratification task, a sensation seeking measure, and IQ measures. In addition, teacher-based assessments of attention-deficit/hyperactivity disorder traits were measured. The results indicated that the majority of children produced meaningful data on the discounting task and discounted rewards hyperbolically. Children with an elevated risk of attention-deficit/hyperactivity disorder showed a trend towards discounting future rewards on the delay discounting task more steeply than did those at low risk. However, delay discounting was unrelated to either delay of gratification or sensation seeking. We interpret these results as providing some support for the use of delay discounting as a measure of intertemporal choice in children, although the results also suggest that delay discounting and delay of gratification tasks may tap different processes in this population.     

Pairing People with Products: Anthropomorphizing the Object,Dehumanizing the Person

We present the first empirical integration of anthropomorphism and dehumanization, two intrinsically linked processes representing the extent to which the concept of humanness is activated for a given target. Across several experiments, we demonstrate that pairing a person and object in an ad, while focusing respondent attention on the object, leads to its being anthropomorphized and evaluated better compared to presenting it alone. However, compared to presenting a person alone, the same pairing leads to inferior evaluations of the person through a process of dehumanization. We rule out two alternative explanations for these effects, namely the transfer of an object's qualities to the person and consumption associations, and conduct a post‐test that provides additional support for our proposed activation/inhibition of humanness account. Finally, we inspect several moderators, finding that anthropomorphism only occurs with moderately and highly functional objects and dehumanization occurs irrespective of the person's gender or fame. By incorporating the literature on dehumanization, we propose new research questions to motivate future inquiry.     

The role of midfrontal theta oscillations across the development of cognitive control in preschoolers and school‐age children

The development of cognitive control enables children to better resist acting based on distracting information that interferes with the current action. Cognitive control improvement serves different functions that differ in part by the type of interference to resolve. Indeed, resisting to interference at the task‐set level or at the response‐preparation level is, respectively, associated with cognitive flexibility and inhibition. It is, however, unknown whether the same neural mechanism underlies these two functions across development. Studies in adults have revealed the contribution of midfrontal theta (MFT) oscillations in interference resolution. This study investigated whether MFT is involved in the resolution of different types of interference in two age groups identified as corresponding to different latent structures of executive functions. Preschool (4–6 years) and school children (6–8 years) were tested with a task involving interference at the response level and/or the task‐set level while (electroencephalogram) EEG was recorded. Behaviorally, response time and accuracy were affected by task‐set. Both age groups were less accurate when the interference occurred at the task‐set level and only the younger group showed decreased accuracy when interference was presented at the response‐preparation level. Furthermore, MFT power was increased, relative to the baseline, during the resolution of both types of interference and in both age groups. These findings suggest that MFT is involved in immature cognitive control (i.e., preschool and school‐ages), by orchestrating its different cognitive processes, irrespective of the interference to resolve and of the level of cognitive control development (i.e., the degree of differentiation of executive functions).     

Naming and categorization in young children: vocal tact training

In three experiments, 2- to 4-year-old children, following pretraining with everyday objects, were presented with arbitrary stimuli of differing shapes. In Experiment 1A, 9 subjects were trained one common tact response, "zag," to three of these and a second tact, "vek," to another three. In category match-to-sample Test 1, 4 subjects sorted accurately when required only to look at the sample before selecting from five comparisons. The remaining 5 subjects succeeded in Test 2, in which they were required to tact the sample before selecting comparisons. Experiment 1B showed, for 2 of these subjects, that tact training with 12 arbitrary stimuli established two six-member classes that were still intact 6 weeks later. In Experiment 2, 3 new subjects participated in a common tact training procedure that ensured that none of the exemplars from the same class were presented together prior to the test for three-member classes. Two subjects passed category Test 1 and the third passed Test 2. Tests showed subjects' listener behavior in response to hearing /zog/ and /vek/ to be in place. These experiments indicate that common naming is effective in establishing arbitrary stimulus classes and that category match-to-sample testing provides a robust measure of categorization.     

L'annee psychologique: history of the founding of a 100-year-old

The authors present the history of the founding of the French journal L'Annee Psychologique. The names of Theodule Ribot (1839-1916), Henry Beaunis (1830-1921), and Alfred Binet (1857-1911) are closely associated with the journal. Ribot's election to the chair of Experimental and Comparative Psychology at the College de France in 1888 marked the official emancipation of psychology in France. Because there was no laboratory associated with the chair, Beaunis, a physiological psychologist from Nancy, proposed to Ribot the creation of the first French laboratory of experimental psychology (1889). Under Beaunis's direction, this laboratory was established at the Sorbonne in Paris but was in fact dependent on another educational institution, L'Ecole Pratique des Hautes Etudes. In 1893 the laboratory's research was first published in a yearly journal named Travaux du Laboratoire de Psychologie Physiologique (2 volumes: 1893-1894). Binet, who joined the laboratory in 1891, was not satisfied by the form of this publication. With Beaunis's agreement, he then created L'Annee Psychologique in 1894 to develop the reputation of the laboratory's research. The authors present the evolution and vicissitudes of the journal from 1895 to 1912, with a glance up to the present.
