A Positive Perspective on Attentional Bias: Positive Affectivity and Attentional Bias to Positive Information

In recent years there has been growing interest in determining the attentional basis of positive affectivity. Investigators have sought to evaluate the hypothesis that elevated positive affectivity is characterized by an attentional bias that favours the processing of positive information over neutral information. Unfortunately, in the studies carried out to date, the assessment procedures used by researchers to assess such attentional selectivity have either been methodologically limited or methodologically flawed. Hence, the validity of the hypothesis has remained indeterminate. To overcome the problems associated with attentional assessment procedures used in previous studies, and so shed light on the attentional basis of positive affectivity, we employed an appropriate variant of the attentional probe task. Our findings show that participants high in positive affectivity displayed greater relative attention to positive information compared to neutral information, than was the case for their low positive affectivity counterparts. Thus, the present results support the hypothesis that an attentional bias to positive information, relative to neutral information, is characteristic of elevated positive affectivity.     

Trait compassion is associated with the neural substrate of empathy

Individual differences in the personality trait Agreeableness underlie humans’ ability to interpret social cues and coordinate effectively with others. However, previous investigations of the neural basis of Agreeableness have yielded largely inconsistent results. Recent evidence has demonstrated that Agreeableness can be divided into two, correlated subdimensions. Compassion reflects tendencies toward empathy, sympathy, and concern for others, while Politeness reflects tendencies toward compliance and refraining from aggression and exploitation. The present study seeks to clarify the neural substrates of Agreeableness by examining whether structural differences in the brain show distinct associations with Compassion and Politeness. Results of a meta-analysis of fMRI studies examining empathy were used to generate hypotheses about the brain regions and networks that underlie trait Compassion. Results of a large-scale structural neuroimaging investigation (N = 275) were largely consistent with the meta-analysis: Compassion was positively correlated with gray matter volume in the bilateral anterior cingulate cortex (ACC) and anterior insula (AI). Further, these differences appear to be associated with Compassion specifically, as opposed to Politeness, suggesting that these two traits have at least partially distinct neuroanatomical substrates.     

Binding object features to locations: Does the “spatial congruency bias” update with object movement?

One of the fundamental challenges of visual cognition is how our visual systems combine information about an object’s features with its spatial location. A recent phenomenon related to object–location binding, the “spatial congruency bias,” revealed that two objects are more likely to be perceived as having the same identity or features if they appear in the same spatial location, versus if the second object appears in a different location. The spatial congruency bias suggests that irrelevant location information is automatically encoded with and bound to other object properties, biasing perceptual judgments. Here we further explored this new phenomenon and its role in object–location binding by asking what happens when an object moves to a new location: Is the spatial congruency bias sensitive to spatiotemporal contiguity cues, or does it remain linked to the original object location? Across four experiments, we found that the spatial congruency bias remained strongly linked to the original object location. However, under certain circumstances—for instance, when the first object paused and remained visible for a brief time after the movement—the congruency bias was found at both the original location and the updated location. These data suggest that the spatial congruency bias is based more on low-level visual information than on spatiotemporal contiguity cues, and reflects a type of object–location binding that is primarily tied to the original object location and that may only update to the object’s new location if there is time for the features to be re-encoded and rebound following the movement.     

Eating together apart: patterns of segregation in a multi‐ethnic cafeteria

Research on segregation has tended to focus on relations located at a macro‐spatial level of analysis and unfolding in contexts where boundaries to interaction are formally established. This research, by contrast, investigated segregation as a micro‐ecological process by observing patterns of seating in a multi‐ethnic cafeteria. A total of 3114 seating positions were coded over a 2‐week period and the resulting data were analysed using both adapted segregation indices (P and D) and loglinear and logistic regression techniques. The results suggested that ethnic segregation existed both at the level of interactional groups and in the form of broader patterns of racial clustering and dispersal in the cafeteria. Moreover, the magnitude of segregation was predicted by the gender composition of seating groups and by variations in the density of the cafeteria's population over time. Some implications of these results for social psychological research on contact and desegregation are considered. Copyright © 2004 John Wiley & Sons, Ltd.     

The relationship between three auditory inspection time tasks and general intelligence

Three inspection-time tasks measuring the amount of time required to discriminate differences in pitch, loudness and phase were administered alongside the Multidimensional Ability Battery and Raven’s Advanced Progressive Matrices to 75 undergraduate students. The auditory tasks were administered adaptively, and thresholds were estimated by fitting a logistic function to each set of data. After correcting for restriction of range the three thresholds intercorrelated significantly, and correlated between −0.33 and −0.68 with scores on the ability tests. A composite auditory inspection time score correlated between −0.35 and −0.42 with the ability measures (−0.50 to −0.54 after correction). Although strategy-use enhanced performance on the pitch inspection-time task, strategy use was unrelated to intelligence and did not mediate the correlation between inspection time and intelligence.     

Integration versus separation in Stroop‐like counting interference tasks1

Abstract: Two versions of a Stroop‐like counting interference task were compared to examine how irrelevant information is ignored. In the integrated task, participants enumerated digits (inconsistent condition) or letters (neutral condition) while attempting to ignore the identity of the characters. In the newly created separated task, participants enumerated asterisks while attempting to ignore a single digit (inconsistent condition) or letter (neutral condition) at fixation. Interference (longer responses in the inconsistent condition than in the neutral condition) was small but significant in both tasks but was not reduced by separation. Contrasted with the pattern in the color–word Stroop task, these results suggest that dimensional separation has different effects on interference depending on the overall amount of interference.     

"Frequent frames" in German child-directed speech: a limited cue to grammatical categories

Mintz (2003) found that in English child-directed speech, frequently occurring frames formed by linking the preceding (A) and succeeding (B) word (A_x_B) could accurately predict the syntactic category of the intervening word (x). This has been successfully extended to French (Chemla, Mintz, Bernal, & Christophe, 2009). In this paper, we show that, as for Dutch (Erkelens, 2009), frequent frames in German do not enable such accurate lexical categorization. This can be explained by the characteristics of German including a less restricted word order compared to English or French and the frequent use of some forms as both determiner and pronoun in colloquial German. Finally, we explore the relationship between the accuracy of frames and their potential utility and find that even some of those frames showing high token-based accuracy are of limited value because they are in fact set phrases with little or no variability in the slot position.
