Coaction and upward social comparison reduce the illusory conjunction effect: Support for distraction-conflict theory

This article proposes an integration of Festinger’s (1954) social comparison theory and Baron’s (1986) distraction-conflict theory of the social facilitation-inhibition effect, which successfully predicts attentional focusing in coaction when social comparison represents a distraction. Two experiments confronted participants with the illusory conjunction task (Treisman, 1998), where illusions occur because of the lack of attentional processing of central cues. If coaction, like upward comparison, is distracting and thereby enhances the attention allocated to central cues (here the target’s features) at the expense of peripheral cues (here distractors), then a reduction should be found in the illusions. Experiment 1 indeed showed a lower rate of conjunctive errors under upward comparison than under downward comparison. Experiment 2 specified that this effect was due to downward comparison effectively reducing distraction, with upward comparison only maintaining it, as compared to mere coaction.     

Stephen Hawking and the virtue of discretion

Jacques Arnould thanks Stephen Hawking for his warning, but then quickly moves on to contend: the present moment provides an opportunity for Homo sapiens on Earth to rediscover the virtue of discretion.     

Delay discounting: Interactions between personality and cognitive ability

Delay discounting describes the extent to which the value of a reward decreases as the delay to obtaining that reward increases. Lower discounting rates predict better outcomes in social, academic, and health domains. The current study investigates how personality and cognitive ability interact to predict individual differences in delay discounting. Extraversion was found to predict higher discounting rates at the low end of the cognitive distribution, while emotional stability was found to predict lower discounting rates at the high end of the cognitive distribution. These findings support recent models of discounting behavior and suggest that personality and cognitive ability interact in shaping decision making.     

Two-to-three-year-old children's interactions with peers in child-care centres: Effects of spatial distance to caregivers

In child-care centres, the influence of caregivers on the development of peer interactions seems ambivalent and mixed results are reported in the literature. Adopting an environmental approach, we examined the effects of the caregivers’ spatial proximity on children's social behaviour. The study was carried out with 175 children (18-40 months) in 12 child-care-centre groups. Children's behaviours were observed during free plays, and both children and caregivers’ locations were recorded. When peers were nearby, children's social behaviours were compared when they were in the immediate proximity (within 2 m) and out of the immediate proximity of a caregiver. Results show that in the latter situation children spend substantially more time addressing social overture to peers and interacting with them; positive interactions with peers show a particularly marked difference. This pattern of results is exhibited by the greater part of the children. Whatever the child-care-centre group, the age subgroup or the gender considered similar results are found. Results also demonstrate that when children are in the immediate proximity of caregivers they are socially oriented towards the attractive adult partners rather than towards peers.     

Does multitasking mediate the relationships between episodic memory,attention, executive functions and apathetic manifestations in traumatic brain injury?

Apathy is frequently described in patients with traumatic brain injury (TBI); its negative consequences particularly affect functional independence. Among apathetic manifestations, lack of initiative and lack of interest have mainly been associated with cognitive impairments. However, few studies have been conducted to precisely identify the underlying cognitive processes. Our aims were (1) to determine the best predictor of apathy from among several cognitive processes, including episodic memory and attention/executive mechanisms and multitasking, and (2) to examine to what extent multitasking could mediate the relationships between specific cognitive processes and lack of initiative/interest. Seventy participants (34 patients with TBI matched with 36 control participants) were given a questionnaire to assess anxio‐depressive symptoms, four tasks to assess specific cognitive processes, and one task to assess real‐life multitasking. Participants’ relatives completed an apathy questionnaire. Multitasking, as assessed by the number of goals not achieved, was the only significant predictor of apathetic manifestations. In addition, the mediation analyses revealed that multitasking performance mediated the relationships between verbal episodic memory and lack of initiative/interest, whereas executive and attentional functions were only indirectly related to lack of initiative/interest due to their significant impacts on multitasking. These results shed new light on the aetiology of apathetic manifestations in patients with TBI, indicating how specific cognitive deficits are expressed in real‐life multitasking, and consequently, how they may lead to the development and/or maintenance of apathetic manifestations.

The Time Before Us (The Unpast in W. S. Merwin,W. Benjamin,and V. Woolf)

Freud and Winnicott have expressed the opinion that if their psychoanalytic ideas are correct, then poets and writers will have thought of them first. The author of the present article, who, in a previous work, has developed the concept of “actual time” on metapsychological grounds, concurs with their opinion by showing that variants of “actual time” can be found in the works of the American poet W. S. Merwin, the British writer Virginia Woolf, and the German philosopher Walter Benjamin. Their poetry, literary prose, and philosophy, respectively, are shown to resonate with the time dimension of the psychoanalytic process.
