Driving anger and other driving-related behaviors in high and low ADHD symptom college students

This study examined differences between college students with high and low symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD). Fifty-nine introductory psychology students completed ADHD diagnostic measures and were compared on measures of driving anger and driving anger expression; accident-related, aggressive, and risky driving behaviors; general anger; and general anger expression. Results indicated high ADHD symptom college students experience more driving anger, display such anger in more hostile/aggressive ways, are more aggressive and risky on the road, experience more crash-related outcomes, are more generally angry, and tend to display anger in socially unacceptable ways. Results are discussed in regard to the understanding and treatment of ADHD.     

The N400 component in parents of children with specific language impairment

Children with specific language impairment (SLI) often have a family history of language disorder. In this study, ERPs in response to a visual semantic priming task were recorded in parents of children with SLI. Despite equal performance, the ERPs displayed differences in language processing: larger N400 amplitudes indicated that the parents, especially the fathers, were less primed by the preceding context. Difference waveforms showed that the fathers of SLI children, contrary to controls, had less differentiated responses to congruent versus incongruent sentences. We propose that the N400 observations may be residual markers of past language deficiencies in the fathers. No differences in the N400 effect were found in the mothers of SLI children.     

Positive, negative, and neutral peer interactions as indicators of children's social competency: the issue of concurrent validity

Many studies examining the effects of treatments for socially isolated/withdrawn children have used behavioral measures to assess children's peer relations. In an attempt to examine the concurrent validity of these measures, we observed 258 preschool children during free play and coded their interactions into the categories of positive, negative, and neutral behaviors. We also interviewed these children individually, using a sociometric nomination procedure, and asked them to indicate liked and disliked peers. Our examination of the results revealed that, consistent with other research, the correlation between the sociometric measures and the children's total rate of interaction with peers was low. In addition, measures of positive, negative, and neutral behaviors were also only weakly correlated with the children's sociometric scores. We agree with others in concluding that multiple methods of assessment are needed to properly assess the adequacy of children's peer relations.     

Auditory coding of visual patterns for the blind

Recognition tasks of simple visual patterns have been used to assess an early visual--auditory sensory-substitution system, consisting of the coupling of a rough model of the human retina with an inverse model of the cochlea, by means of a pixel-frequency relationship. The potential advantage of the device, compared with previous ones, is to give the blind the ability to both localise and recognise visual patterns. Four evaluation sessions assessed the performance of twenty-four blindfolded sighted subjects using the device. Subjects had to recognise twenty-five visual patterns, one at a time, using a head-mounted small camera and interpreting the corresponding sounds given by the device. Half the subjects were trained by means of a correction feedback procedure during ten one-hour training sessions embedded in between the evaluation sessions. Results revealed extremely successful training effects. Performance of trained subjects significantly increased with practice compared with the untrained control group. The improvement was also observed for new patterns, demonstrating a learning-process generalisation. The negative correlation observed between scores and processing time showed that the subjects' response accuracy was related to their speed. In conclusion, simple pattern recognition is possible with a fairly natural vision-to-audition coding scheme, given the possibility for the subjects to have sensory--motor interactions while using the device.     

Role of anxiety and brooding in specificity of autobiographical recall

Overgeneral schemas and lack of autobiographical memory (AM) specificity about our past experiences can predict mood disturbance. Rumination, functional avoidance and executive processes are the main explanatory variables of such overgenerality. However, in non‐clinical samples, rumination predicts overgenerality most consistently after the induction of dysphoric mood. Anxiety also activates rumination. Furthermore, anxiety predicts memory performance and has effects on mood which are independent of the effects of rumination. So, what might be the role of anxiety in autobiographical memory performance? A sample of 210 voluntary participants reported measures of autobiographical memory, anxiety, rumination (brooding and reflection), functional avoidance and executive functions (semantic and phonetic verbal fluency task). Autobiographical performance (specificity) was negatively associated with brooding and age and positively with phonetic verbal fluency but not with functional avoidance and anxiety. However, anxiety and brooding were positively correlated even after controlling for depression scores. Moreover, using structural equation modeling, anxiety showed a significant indirect effect on autobiographical specificity through brooding rumination. These results suggest a possible association of anxiety with autobiographical recall through brooding rumination.     

Self‐perception of cognitive changes during pregnancy and the early postpartum: salience and attentional effects

The reports from 198 pregnant women of changes experienced during pregnancy suggested that cognitive changes are not salient since only 2% of women spontaneously mentioned such changes. When asked specifically about cognitive changes, the majority reported no change although most who reported a change indicated it was for the worse. In this respect they differed from a group of 132 students who had recently left home. In a second study, 13 women were asked to rate a range of cognitive functions during pregnancy and the postpartum period. Their ratings for certain aspects of cognition were lower than those of a group of non‐pregnant women. They also reported more cognitive failures and readily provided examples of perceived impairments in cognition. It would appear that cognitive deficits are of low salience to pregnant women but, if prompted, impairments in memory, concentration, clarity of thought and attention will be reported by women both during pregnancy and the first‐year postpartum.

Innovativeness and the effects of urbanization on risk-taking behaviors in wild Barbados birds

The effects of urbanization on avian cognition remain poorly understood. Risk-taking behaviors like boldness, neophobia and flight distance are thought to affect opportunism and innovativeness, and should also vary with urbanization. Here, we investigate variation in risk-taking behaviors in the field in an avian assemblage of nine species that forage together in Barbados and for which innovation rate is known from previous work. We predicted that birds from highly urbanized areas would show more risk-taking behavior than conspecifics from less urbanized parts of the island and that the differences would be strongest in the most innovative of the species. Overall, we found that urban birds are bolder, less neophobic and have shorter flight distances than their less urbanized conspecifics. Additionally, we detected between-species differences in the effect of urbanization on flight distance, more innovative species showing smaller differences in flight distance between areas. Our results suggest that, within successful urban colonizers, species differences in innovativeness may affect the way species change their risk-taking behaviors in response to the urban environment.     

3-D processing in the Poggendorff illusion

In the Poggendorff illusion two collinear oblique lines, separated by two vertical lines, appear to be misaligned. 3-D processing of the oblique but not the vertical lines is considered to cause this apparent misalignment. We investigated whether more explicitly triggering 2-D versus 3-D interpretations of the different parts of Poggendorff-like displays would influence the apparent misalignment. In Experiment 1, we found that compared to 2-D controls, 3-D interpretations of the vertical parts did not influence apparent misalignment, while for the oblique parts 3-D processing resulted in more apparent misalignment than 2-D controls. In Experiment 2, the amount of contour convergence of the oblique parts was manipulated resulting in the 3-D blocks, but not the 2-D line patterns, to be perceived as receding in depth. Now, apparent misalignment increased the more the 3-D blocks were perceived as receding in depth. We conclude that apparent misalignment in Poggendorff-like displays can be influenced by different interpretations of its separate parts, while keeping the local junctions between the different elements the same.     

Does it only depend on the point of view? Perspective-related differences in justice evaluations of negative incidents in personal relationships

A series of four studies investigated systematic differences between actor and recipient interpretations and justice evaluations of negative incidents in interpersonal relationships. Due to a refined methodology, each negative incident was assessed both by the respective recipient and actor, and each participant reported incidents from both perspectives. The studies provided clear evidence of systematic recipient-actor differences and showed that the quality of the relationship between the parties involved in the incidents can moderate the occurrence and shape of the differences. Significant gender differences were found showing that women respond more accusingly than men in the role of the recipient and more defensively than men in the role of the actor.
