The time course of visual influences in letter recognition

This study builds on a specific characteristic of letters of the Roman alphabet—namely, that each letter name is associated with two visual formats, corresponding to their uppercase and lowercase versions. Participants had to read aloud the names of single letters, and event-related potentials (ERPs) for six pairs of visually dissimilar upper- and lowercase letters were recorded. Assuming that the end product of processing is the same for upper- and lowercase letters sharing the same vocal response, ERPs were compared backward, starting from the onset of articulatory responses, and the first significant divergence was observed 120 ms before response onset. Given that naming responses were produced at around 414 ms, on average, these results suggest that letter processing is influenced by visual information until 294 ms after stimulus onset. This therefore provides new empirical evidence regarding the time course and interactive nature of visual letter perception processes.     

Age and active navigation effects on episodic memory: A virtual reality study

We investigated the navigation‐related age effects on learning, proactive interference semantic clustering, recognition hits, and false recognitions in a naturalistic situation using a virtual apartment‐based task. We also examined the neuropsychological correlates (executive functioning [EF] and episodic memory) of navigation‐related age effects on memory. Younger and older adults either actively navigated or passively followed the computer‐guided tour of an apartment. The results indicated that active navigation increased recognition hits compared with passive navigation, but it did not influence other memory measures (learning, proactive interference, and semantic clustering) to a similar extent in either age group. Furthermore, active navigation helped to reduce false recognitions in younger adults but increased those made by older adults. This differential effect of active navigation for younger and older adults was accounted for by EF score. Like for the subject‐performed task effects, the effects from the navigation manipulation were well accounted for by item‐specific/relational processing distinction, and they were also consistent with a source monitoring deficit in older adults.     

Social influence on metacognitive evaluations: The power of nonverbal cues

Metacognitive evaluations refer to the processes by which people assess their own cognitive operations with respect to their current goal. Little is known about whether this process is susceptible to social influence. Here we investigate whether nonverbal social signals spontaneously influence metacognitive evaluations. Participants performed a two-alternative forced-choice task, which was followed by a face randomly gazing towards or away from the response chosen by the participant. Participants then provided a metacognitive evaluation of their response by rating their confidence in their answer. In Experiment 1, the participants were told that the gaze direction was irrelevant to the task purpose and were advised to ignore it. The results revealed an effect of implicit social information on confidence ratings even though the gaze direction was random and therefore unreliable for task purposes. In addition, nonsocial cues (car) did not elicit this effect. In Experiment 2, the participants were led to believe that cue direction (face or car) reflected a previous participant's response to the same question—that is, the social information provided by the cue was made explicit, yet still objectively unreliable for the task. The results showed a similar social influence on confidence ratings, observed with both cues (car and face) but with an increased magnitude relative to Experiment 1. We additionally showed in Experiment 2 that social information impaired metacognitive accuracy. Together our results strongly suggest an involuntary susceptibility of metacognitive evaluations to nonverbal social information, even when it is implicit (Experiment 1) and unreliable (Experiments 1 and 2).

When combined spatial polarities activated through spatio-temporal asynchrony lead to better mathematical reasoning for addition

Several recent studies have supported the existence of a link between spatial processing and some aspects of mathematical reasoning, including mental arithmetic. Some of these studies suggested that people are more accurate when performing arithmetic operations for which the operands appeared in the lower-left and upper-right spaces than in the upper-left and lower-right spaces. However, this cross-over Horizontality × Verticality interaction effect on arithmetic accuracy was only apparent for multiplication, not for addition. In these studies, the authors used a spatio-temporal synchronous operand presentation in which all the operands appeared simultaneously in the same part of space along the horizontal and vertical dimensions. In the present paper, we report studies designed to investigate whether these results can be generalized to mental arithmetic tasks using a spatio-temporal asynchronous operand presentation. We present three studies in which participants had to solve addition (Study 1a), subtraction (Study 1b), and multiplication (Study 2) in which the operands appeared successively at different locations along the horizontal and vertical dimensions. We found that the cross-over Horizontality × Verticality interaction effect on arithmetic accuracy emerged for addition but not for subtraction and multiplication. These results are consistent with our predictions derived from the spatial polarity correspondence account and suggest interesting directions for the study of the link between spatial processing and mental arithmetic performances.     

French translation and validation of the Karitane Parenting Confidence Scale

IntroductionPerceived parental self-efficacy (PSE) is thought to play a crucial role in parental well-being, the parent-infant relationship, and other aspects of infant development, particularly in the early postnatal period. The Karitane Parenting Confidence Scale (KPCS) is a 15-item self-report questionnaire designed for parents with infants aged 0–12 months.ObjectiveTo explore the factor structure of a French translation of the KPCS and assess its psychometric qualities.MethodUsing a French-language translation of the KPCS (KPCS-F), 257 parents of children aged 0–12 months were recruited via childcare structures (e.g. nurseries, community centers, mother and child protection centers). Confirmatory factor analyses (CFA) were conducted to examine 2- and 3-factor solutions for the KPCS-F scale. Internal reliability and convergent validity were evaluated.ResultsThe best model was a two-factor solution (PSE “infant care” and PSE “parental role”) restricted to 12 items. Sound internal consistency was indicated, with a Cronbach's alpha coefficient of 0.80 and a McDonald's omega coefficient of 0.80. Test-retest reliability was good. KPCS-F score was correlated with social support and psychological well-being scores.ConclusionThe KPCS-F showed substantial validity and reliability for this sample. The translated scale should therefore improve assessment and intervention processes for professionals working with parents of young children.     

Avoiding affect in intergroup relations: The roles of dispositional and intergroup empathy in the relationship between alexithymia and prejudice

Alexithymia, that is, difficulties in recognizing, communicating, and processing one's own emotions, is associated with poorer interpersonal relations. Emotional processes are key drivers and mechanisms of prejudice and its reduction, and alexithymia is thought to influence individuals' empathic responses. This research examined the relationship between alexithymia and prejudice, and the role of empathy in this relationship. Three studies were conducted in three intergroup contexts to test whether alexithymia is also associated with poorer intergroup relations with lesbian, gay, bisexual, and transgender+ individuals (Study 1, N = 126 heterosexual late adolescents) and Asian British people (Study 3, N = 300 White adults) in the United Kingdom, and immigrants in Italy (Study 2, N = 381 Italian adults). Participants completed the Toronto Alexithymia Scale (TAS-20), measures on dispositional and intergroup empathic concern (EC) and perspective taking (PT) as well as measures of prejudice (anti-outgroup hostility, anti-outgroup attitudes, and anti-outgroup behavioral intentions). Lower dispositional EC (Studies 1, marginal effect in Study 2) and intergroup EC and PT (Study 3) mediated the relationship between the Externally Oriented Thinking subscale of the TAS-20 (i.e., avoiding emotions and affective thinking) and greater prejudice. The findings are important for understanding the challenges of late adolescents and adults with alexithymia in intergroup relations, highlighting the role of dispositional and intergroup empathy for individual differences such as alexithymia in endorsing prejudice.
