Fragile visual short-term memory is an object-based and location-specific store

Fragile visual short-term memory (FM) is a recently discovered form of visual short-term memory. Evidence suggests that it provides rich and high-capacity storage, like iconic memory, yet it exists, without interference, almost as long as visual working memory. In the present study, we sought to unveil the functional underpinnings of this memory storage. We found that FM is only completely erased when the new visual scene appears at the same location and consists of the same objects as the to-be-recalled information. This result has two important implications: First, it shows that FM is an object- and location-specific store, and second, it suggests that FM might be used in everyday life when the presentation of visual information is appropriately designed.     

La gestion de la souffrance par le psychologue clinicien. Étude des impacts et des stratégies de coping

We focus in this study on strategies used by clinical psychologists to cope with their own or patient psychological distress in the framework of help relationship. A self-administered form was sent to listings of professionals by e-mail. The sample is made of 187 French clinical psychologists. To cope with patients’ suffering, psychologists use mostly avoidance coping style. And the strategies they prefer are “supervision”, “personal therapy” and “speaking with colleagues” (problem focused coping strategies). To cope with their own distress, which has a lot of negative impacts on help relationship, psychologists have most frequently a problem focused coping style but their favourite strategy is to “lighten their schedules”. And almost a quarter of the sample presents a significant level of distress. In conclusion, results show that psychological distress management by psychologists is an important question with a lot of ethical questions.     

Evidence Supporting the Importance of Peripheral Visual Information for the Directional Control of Aiming Movement

The focus of the present study was on determining whether the high level of directional accuracy found in aiming studies in which the subjects can see their hand in the visual periphery supports the existence of a kinetic visual channel or, rather, the advantage of binocular over monocular vision for movement directional control. The limits of this kinetic visual channel were also explored. The results of the 1st experiment indicated that seeing one's hand in the visual periphery is sufficient to ensure optimal directional aiming accuracy. Further, no differences in aiming accuracy were noted between monocular and binocular vision. These results supported the existence of a visual kinetic channel. In the 2nd experiment, whether this kinetic visual channel would operate with movements slower (55°/s) than those usually used in studies that had proved its existence (over 110°/s) was determined. The results indicated that this visual kinetic channel was operative even at relatively slow movement velocities. Central vision of the hand seemed to be used for on-line directional control of relatively slow movements.     

Relationships among Negative Emotionality,Responsive Parenting and Early Socio‐cognitive Development in Korean Children

The present study examined the interplay among negative emotionality, responsive parenting and socio‐cognitive developmental outcomes (i.e., communication, personal‐social and problem‐solving outcomes) in about 1620 Korean children using three waves of longitudinal data spanning the first 2 years of their life. Results from the Structural Equation Modeling (SEM) demonstrated that there were moderate to low degrees of stability in negative emotionality, responsive parenting and socio‐cognitive developmental outcomes from infancy to toddlerhood. Evidence for reciprocity in the parent–child relationship was found; responsive parenting predicted higher levels of subsequent child communication (in infancy and toddlerhood), and infants' higher problem‐solving ability predicted higher responsive parenting in toddlerhood. Overall, the cross‐age associations among the variables were similar between boys and girls, but some different patterns were observed: when controlling for family contextual factors and the within‐time correlations, negative emotionality at an earlier point significantly predicted lower responsive parenting at a later point and vice versa only in girls during infancy, but neither in boys nor in toddlerhood. The implications of these findings are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Emotional plasticity: conditions and effects of improving emotional competence in adulthood

This study aimed to investigate (a) whether it is possible to increase emotional competence (EC) in adulthood; (b) whether this improvement results in better mental, physical, and social adjustment; (c) whether this improvement can be maintained 1 year later; and (d) whether these benefits are accompanied by a reduction in stress-hormone secretion (i.e., cortisol). One hundred and thirty-two participants were randomly assigned to an EC-enhancing intervention (in group format) or to a control group. Participants in the intervention group underwent a specifically designed 15-hr intervention targeting the 5 core emotional competencies, complemented with a 4-week e-mail follow-up. Results reveal that the level of emotional competencies increased significantly in the intervention group in contrast with the control group. This increase resulted in lower cortisol secretion, enhanced subjective and physical well-being, as well as improved quality of social and marital relationships in the intervention group. No significant change occurred in the control group. Peer reports on EC and quality of relationships confirmed these results. These data suggest that emotional competencies can be improved, with effective benefits on personal and interpersonal functioning lasting for at least 1 year. The theoretical implications of these results as well as their practical implications for the construction and the development of effective emotional competencies interventions are discussed.     

Discrimination of human and dog faces and inversion responses in domestic dogs (Canis familiaris)

Although domestic dogs can respond to many facial cues displayed by other dogs and humans, it remains unclear whether they can differentiate individual dogs or humans based on facial cues alone and, if so, whether they would demonstrate the face inversion effect, a behavioural hallmark commonly used in primates to differentiate face processing from object processing. In this study, we first established the applicability of the visual paired comparison (VPC or preferential looking) procedure for dogs using a simple object discrimination task with 2D pictures. The animals demonstrated a clear looking preference for novel objects when simultaneously presented with prior-exposed familiar objects. We then adopted this VPC procedure to assess their face discrimination and inversion responses. Dogs showed a deviation from random behaviour, indicating discrimination capability when inspecting upright dog faces, human faces and object images; but the pattern of viewing preference was dependent upon image category. They directed longer viewing time at novel (vs. familiar) human faces and objects, but not at dog faces, instead, a longer viewing time at familiar (vs. novel) dog faces was observed. No significant looking preference was detected for inverted images regardless of image category. Our results indicate that domestic dogs can use facial cues alone to differentiate individual dogs and humans and that they exhibit a non-specific inversion response. In addition, the discrimination response by dogs of human and dog faces appears to differ with the type of face involved.     

A mixed Rasch model of dual-process conditional reasoning

A fine-grained dual-process approach to conditional reasoning is advocated: Responses to conditional syllogisms are reached through the operation of either one of two systems, each of which can rely on two different mechanisms. System1 relies either on pragmatic implicatures or on the retrieval of information from semantic memory; System2 operates first through inhibition of System1, then (but not always) through activation of analytical processes. It follows that reasoners will fall into one of four groups of increasing reasoning ability, each group being uniquely characterized by (a) the modal pattern of individual answers to blocks of affirming the consequent (AC), denying the antecedent (DA), and modus tollens (MT) syllogisms featuring the same conditional; and (b) the average rate of determinate answers to AC, DA, and MT. This account receives indirect support from the extant literature and direct support from a mixed Rasch model of responses given to 18 syllogisms by 486 adult reasoners.     

Socially dependent auditory laterality in domestic horses (Equus caballus)

Laterality is now known to be an ubiquitous phenomenon among the vertebrates. Particularly, laterality of auditory processing has been demonstrated in a variety of species, especially songbirds and primates. Such a hemispheric specialization has been shown to depend on factors such as sound structure, species specificity and types of stimuli. Much less is known on the possible influence of social familiarity although a few studies suggest such an influence. Here we tested the influence of the degree of familiarity on the laterality of the auditory response in the domestic horse. This species is known for its social system and shows visible reactions to sounds, with one or two ears moving towards a sound source. By comparing such responses to the playback of different conspecific whinnies (group member, neighbor and stranger), we could demonstrate a clear left hemisphere (LH) preference for familiar neighbor calls while no preference was found for group member and stranger calls. Yet, we found an opposite pattern of ear side preference for neighbor versus stranger calls. These results are, to our knowledge, the first to demonstrate auditory laterality in an ungulate species. They open further lines of thought on the influence of the social “value” of calls and the listener’s arousal on auditory processing and laterality.     

Stereotype endorsement and perceived ability as mediators of the girls' gender orientation–soccer performance relationship

ObjectiveThis study investigated girls' endorsement of the stereotype that girls are not good soccer performers through three questions: (1) did stereotype endorsement predict soccer performance? (2) Was this relationship mediated by perceived ability? (3) Was stereotype endorsement related to gender role orientation?MethodOne hundred and two junior high school girls from the 6th to the 9th grade (M age = 13.5 years, SD = 1.23) reported their beliefs about girls' and boys' performance in soccer, perceived ability and gender role orientation. Next, their soccer performance was observed during matches in compulsory physical education classes. A path-analytic model tested the relationships among the variables using a product-moment correlation matrix and a maximum likelihood estimation procedure.ResultsStereotype endorsement (i.e., the belief that girls' performance in soccer is poor) negatively predicted performance, this relationship being mediated by perceived ability. Moreover, masculinity positively predicted perceived ability, and this relationship was partially mediated by stereotype endorsement.ConclusionThis study reinforces the idea that girls' sports performance may be related to gender stereotypes. Interpretations of the results in light of Eccles et al.’s expectancy-value model and stereotype threat theory are discussed, along with implications for practice.
