Adoptive versus Mixed Families: Child Adjustment,Parenting Stress and Family Environment

Recent research in adoption has considered the factors and processes that underlie the adjustment of children and families. However, little research has been conducted on certain types of adoptive families, specifically on families with both adoptive and biological children often designated as mixed families. This subject is addressed by the present study which also analyzes the association between the type of adoptive family and children’s outcomes—prosocial and problem behavior—parenting stress and the relational family environment. It also examines whether children’s gender, age at adoption and the number of children in the home moderate these effects. 102 parents of adoptive children (ACF) 33 parents of both adoptive and biological children (ABCF) and 102 parents of biological children (BCF) participated in the study. Target-children were aged from 6 to 12 years. The Portuguese versions of the SDQ-P, PSI-SF and FES (Interpersonal Relationship dimension) were used. Results showed that the type of adoptive family—ACF and ABCF—significantly explained the variance of children’s behavioral problems and parenting stress. The child’s gender was shown to moderate the relationship between ACF parents and their perception of child’s prosocial behavior. The results give relevant clues as to the importance of distinct outcomes in adoptive families—ACF and ABCF—compared to families with only biological children and should, therefore, be a resource for professionals involved in the adopters’ suitability assessment and adoption intervention.     

How holistic processing of faces relates to cognitive control and intelligence

The Vanderbilt Holistic Processing Test for faces (VHPT-F) is the first standard test designed to measure individual differences in holistic processing. The test measures failures of selective attention to face parts through congruency effects, an operational definition of holistic processing. However, this conception of holistic processing has been challenged by the suggestion that it may tap into the same selective attention or cognitive control mechanisms that yield congruency effects in Stroop and Flanker paradigms. Here, we report data from 130 subjects on the VHPT-F, several versions of Stroop and Flanker tasks, as well as fluid IQ. Results suggested a small degree of shared variance in Stroop and Flanker congruency effects, which did not relate to congruency effects on the VHPT-F. Variability on the VHPT-F was also not correlated with Fluid IQ. In sum, we find no evidence that holistic face processing as measured by congruency in the VHPT-F is accounted for by domain-general control mechanisms.     

Lean back and relax: Reclined seating position buffers the effect of frustration on anger and aggression

Frustration is a powerful instigator of anger‐based aggression. We hypothesized that the impact of a frustration on anger and aggressive behavior is reduced in a state of feeling relaxed, which is considered incompatible with the experience of anger. Seventy‐nine participants received frustrating feedback either when sitting upright or sitting in a reclined position and were then given a chance to act aggressively toward the frustrator. Feelings of anger and relaxation were assessed before and after the frustration. Participants in the reclined position felt more relaxed than those sitting upright, which indirectly predicted less aggressive behavior via lower anger. The results are consistent with theories of incompatible states and embodiment and have implications for using body‐related cues to mitigate anger‐based aggression.     

Dissociating viewpoint costs in mental rotation and object recognition

In a mental rotation task, participants must determine whether two stimuli match when one undergoes a rotation in 3-D space relative to the other. The key evidence for mental rotation is the finding of a linear increase in response times as objects are rotated farther apart. This signature increase in response times is also found in recognition of rotated objects, which has led many theorists to postulate mental rotation as a key transformational procedure in object recognition. We compared mental rotation and object recognition in tasks that used the same stimuli and presentation conditions and found that, whereas mental rotation costs increased relatively linearly with rotation, object recognition costs increased only over small rotations. Taken in conjunction with a recent brain imaging study, this dissociation in behavioral performance suggests that object recognition is based on matching of image features rather than on 3-D mental transformations.     

Font tuning associated with expertise in letter perception

Font tuning (FT) occurs when observers recognize a sequence of letters presented in the same font faster than in different fonts (Sanocki 1987, 1988 Journal of Experimental Psychology. Human Perception and Performance 13 267-278; 14 472-480). Here, we test the hypothesis that FT is associated with expertise with a specific writing system. We developed a systematic search task allowing the measurement of FT over a large number of letters and generalized the finding of FT from English readers viewing Roman letters to Chinese readers viewing Chinese characters. Non-Chinese readers did not show evidence of FT for Chinese characters in this search task. We also used a simpler 3-letter identification task to directly compare novice and expert readers, and to explore FT for different aspects of font such as fill, slant, and aspect ratio. We found that experts tune to aspect ratio but not to the other font changes. These findings reveal that letters are not processed visually in the same manner as shapes, and suggest an explanation for the cortical specialization obtained in the visual system for letters.     

Personal and general belief in a just world as judgement norms

Research on the belief in a just world (BJW) has focused on its intra-individual functions (e.g., psychological well-being) and its inter-individual consequences (e.g., derogation of victims). Recent theorizing, however, has indicated that the BJW may also have more societal functions and consequences, serving as a legitimizing device of the status quo. The studies in the current paper focus on this latter view and are based on Alves and Correia's ( 2008 ) research which found that the expression of high personal and general belief in a just world is injunctively normative. Two experimental studies aimed at ascertaining three issues: (1) the dimension(s) of social value (social utility and/or social desirability) on which the BJW normativity anchors; (2) whether the expression of moderate BJW is also injunctively normative; and (3) whether the injunctive normativity of the BJW is related to perceptions of truth. Results indicate that moderate and high personal and general BJW are normative. Yet, whereas the normativity of personal BJW anchors both on social utility and social desirability, that of general BJW anchors only on social utility. We discuss personal and general BJW as judgement norms, whose normativity may not be personally acknowledged (in the case of general BJW) and does not necessarily derive from being perceived as true, but from the fact that such norms carry social value at least in individualistic societies.     

Multicriteria Classification with Unknown Categories: A Clustering–Sorting Approach and an Application to Conflict Management

This work proposes an approach to cluster and sort a set of alternatives considering multi‐criteria categories with a partial order structure. It can be considered a heuristic approach because it does not attempt to derive an optimal partial order among all conceivable clusters of alternatives. Rather than this, it intends to be a simple approach that is transparent to the Decision Maker (DM) whose assistance is sought to help shaping the results. The approach proposed arises from the conjugation of traditional Clustering analysis and Multi‐criteria sorting tools. At the outset, the number of categories and their characteristics is unknown. First, we need to detect only the clusters themselves on the basis of a similarity measure independent of the preferences of the DM. Next, we detect potential partial order relations that might exist between them, according to the subjective preferences of the DM. Such preferences are elicited only after the DM has examined the clusters detected and deemed that these categories made sense. The new approach performs very well in a real‐world problem of management of intragroup conflicts and conflict handling strategies. Copyright © 2012 John Wiley & Sons, Ltd.
