Infants' Differential Processing of Female and Male Faces

ABSTRACT— Infants show an interesting asymmetry in face processing: They are more fluent in processing female faces than they are at processing male faces. We hypothesize that such processing asymmetry results from greater experience with female faces than with male faces early in development. Asymmetrical face processing may have long-lasting implications for development of face recognition, development of knowledge structures regarding females and males, and social-information processing. We encourage researchers to use both female and male faces in their face-perception research and to conduct separate analyses for female and male faces.     

Le voisinage orthographique influence la catégorisation de couleur des mots différemment selon l’âge et la vitesse de traitement

The objective of this research was to determine to what extent the effect of higher-frequency orthographic neighbourhood in a word colour-categorization task is changed during aging when processing speed is taken into account. In addition, the effect of the lexicality of the stimuli on colour categorization was examined, as well as its variation according to age and processing speed. Fifty-two young adults (M_age = 21.62) and 52 older adults (M_age = 66.04) participated in this study. For each age group, two sub-groups were created according to the processing speed of the participants as measured by the WAIS Coding subtest. Two conditions of words (written in red, yellow, green or blue) were presented in a colour-categorization task. Half of the words did not have any orthographic neighbours (e.g., pistil [pistil]), while the other half had a higher-frequency neighbour (e.g., tirade [tirade]/TIRAGE [draw]). A control condition with a series of Xs was added to test the influence of the effect of the lexicality of words on the colour-categorization times. As a whole, the results showed slower colour-categorization times for words compared to a series of Xs, which did not vary with age and processing speed. Importantly, the results showed that orthographic neighbourhood frequency interacted with age and processing speed, on colour categorization response times. More precisely, the neighbourhood frequency effect was found to vary differently according to processing speed in each age group. For the fastest young adults, the facilitatory effect of higher-frequency orthographic neighbourhood was obtained, whereas no such effect was found for the slowest young adults. The fastest older adults did not exhibit any effect of higher-frequency orthographic neighbourhood whereas a facilitatory effect was observed for the slowest older adults. Therefore, these data suggest that both aging and the processing speed of the participants influence the interference effect of reading on colour categorization. These findings are discussed in the context of cognitive aging theories and models of written word recognition.     

Psychological Essentialism of Human Categories

ABSTRACT— Psychological essentialism is an ordinary mode of category representation that has powerful social-psychological consequences. This article reviews those consequences, with a focus on the distinctive ways people perceive, evaluate, and interact with members of human categories they essentialize. Why and when people engage in this mode of thinking remain open questions. Variability in essentialism across cultures, categories, and contexts suggests that this mode of representing human categories is rooted in a naturalistic theory of category origins, combined with a need to explain differences that cross category boundaries.     

Contagion or restitution? When bad apples can motivate ethical behavior

When there is a “bad apple” in the group, are we more likely to follow the example or compensate for their sins? Three experiments showed that whether a group member’s unethical actions lead to contagion or restitution depends on the presence of out-group observers. In Experiment 1, participants were more likely to compensate for the transgression of an in-group member than an out-group member when there were out-group observers. Experiment 2 varied the presence of out-group observers and showed that such compensatory behaviors occur only in the presence of out-group members. We suggest that the presence of out-group observers trigger a self-categorization process that induces guilt in individuals for their group members’ transgressions. Indeed, associated guilt mediated the relationship between in-group member’s unethical behavior and participants’ compensatory behavior (Experiment 3). These results suggest that norms implied by others’ behavior and group categorization are important determinants of ethical behavior.     

Interracial contexts debilitate same-race face recognition

Social cognitive research has documented the integral role of social categories (e.g., race) in face processing. Activating a social category can lead perception and memory of faces to be biased in a category-consistent direction. The current research extends this past work, to test the hypothesis that making a social category salient can reduce subsequent face recognition. In two experiments, the current research finds that the typically superior same-race recognition is debilitated by making the same-race category salient. We find that when White-Americans self-categorize as ‘White,’ subsequent perceptual and memorial biases reduce the typically strong same-race recognition.     

Bias for consonantal information over vocalic information in 30-month-olds: cross-linguistic evidence from French and English

Using a name-based categorization task, Nazzi found in 2005 that French-learning 20-month-olds can make use of one-feature consonantal contrasts between new labels but fail to do so with one-feature vocalic contrasts. This asymmetry was interpreted as developmental evidence for the proposal that consonants play a more important role than vowels at the lexical level. In the current study using the same task, we first show that by 30 months French-learning infants can make use of one-feature vocalic contrasts (e.g., /pize/–/pyze/). Second, we show that in a situation where infants must neglect either a consonantal one-feature change or a vocalic one-feature change (e.g., match a /pide/ with either a /tide/ or a /pyde/), both French- and English-learning 30-month-olds choose to neglect the vocalic change rather than the consonantal change. We argue that these results suggest that by 30 months of age, infants still give less weight to vocalic information than to consonantal information in a lexically related task even though they are able to process fine vocalic information.     

Answer comparison in automated question answering

In the context of Question Answering (QA) on free text, we assess the value of answer comparison and information fusion in handling multiple answers. We report improvements in answer re-ranking using fusion on a set of location questions and show the advantages of considering candidates as allies rather than competitors. We conclude with some observations about answer modeling and evaluation methodology, arising from a more recent experiment with a larger set of questions and a greater diversity of question types and candidates.     

Why neuroscience matters to cognitive neuropsychology

The broad issue in this paper is the relationship between cognitive psychology and neuroscience. That issue arises particularly sharply for cognitive neurospsychology, some of whose practitioners claim a methodological autonomy for their discipline. They hold that behavioural data from neuropsychological impairments are sufficient to justify assumptions about the underlying modular structure of human cognitive architecture, as well as to make inferences about its various components. But this claim to methodological autonomy can be challenged on both philosophical and empirical grounds. A priori considerations about (cognitive) multiple realisability challenge the thesis on philosophical grounds, and neuroscientific findings from developmental disorders substantiate that challenge empirically. The conclusion is that behavioural evidence alone is inadequate for scientific progress since appearances of modularity can be thoroughly deceptive, obscuring both the dynamic processes of neural development and the endstate network architecture of real cognitive systems.

Reliability and validity of the Multiple Affect Adjective Check List - Revised

A recent factor analysis of the Multiple Affect Adjective Check List (MAACL) changed the Anxiety, Depression, and Hostility scales from bipolar to unipolar scales and added two new scales: Positive Affect and Sensation Seeking. Internal reliability of the MAACL-R scales, computed for normal and patient samples, was adequate for state and trait forms except for Sensation Seeking. Test-retest reliability in college students was higher for the trait form with retest intervals of from 2 to 8 weeks than for the state form with retest intervals of from 2 to 5 days. The pattern of correlations among self-, peer, and counselor ratings and the MAACL-R scales for normal and patient samples indicates improved discriminant validity and equally good convergent validity as the old scales. The use of standard scores that are indexed to the number of items checked reduced scale intercorrelations by controlling the acquiescence set.The financial support of the Weldon Springs Endowment Fund, University of Missouri at Kansas City, toward the completion of this research project is gratefully acknowledged.
