The Impact of the Big Five Personality Traits on Reports of Child Behavior Problems by Different Informants

The present study compared ratings of a standardized sample of child behavior problems across informants and examined the effects of informant personality traits on child behavior ratings by mothers, teachers, and group-care workers. Participants were 55 clinic-referred children, aged 6–12 years. All informants watched and rated the same 17-min videotaped behavior sample of a familiar target child. Independent trained observers rated the same videotapes to provide criterion ratings. Informants personality traits were assessed using the NEO Five Factor Personality Inventory. Results showed that mothers reported fewer behavior problems than did the professionals, that the informants who were familiar with the child reported more behavior problems than did the independent observers, and that higher levels of informant neuroticism were related to higher ratings of child behavior problems in the case of the professionals, but not in the case of the mothers. In addition, group-care workers who were less extraverted and open were likely to report more child behavior problems than group-care workers with normal levels of extraversion and openness. Finally, no relations were found between agreeableness or conscientiousness and ratings of child behavior. Findings suggest that professionals who work with children are not immune to distortions based on their own personality.     

Action comprehension: deriving spatial and functional relations

A perceived action can be understood only when information about the action carried out and the objects used are taken into account. It was investigated how spatial and functional information contributes to establishing these relations. Participants observed static frames showing a hand wielding an instrument and a potential target object of the action. The 2 elements could either match or mismatch, spatially or functionally. Participants were required to judge only 1 of the 2 relations while ignoring the other. Both irrelevant spatial and functional mismatches affected judgments of the relevant relation. Moreover, the functional relation provided a context for the judgment of the spatial relation but not vice versa. The results are discussed in respect to recent accounts of action understanding.     

Detection of sound rise time by adults with dyslexia

Low sensitivity to amplitude modulated (AM) sounds is reported to be associated with dyslexia. An important aspect of amplitude modulation cycles are the rise and fall times within the sound. In this study, simplified stimuli equivalent to just one cycle were used and sensitivity to varying rise times was explored. Adult participants with dyslexia or compensated dyslexia and a control group performed a detection task with sound pairs of different rise times. Results showed that the participants with dyslexia differed from the control group in rise time detection and a correlation was found between rise time detection and reading and phonological skills. A subgroup of participants with lower sensitivity to rise time detection characterized by low accuracy in syllable-level phonological skills was found within the dyslexic group. Short stimuli containing only one rise time produced associations with phonological skills and reading, even in a language where the perception of rise time contrasts are not crucial for the signaling of phonemic contrast.     

The transition from synchronization to continuation tapping

The present study examined changes in timing at the transition from synchronization to continuation tapping and the role played by knowledge of the transition. Three experiments employed a pseudo-synchronization paradigm: At the transition, the pacing tones were replaced by identical feedback tones. In Experiment 1, participants were not informed when the transition would occur. Immediately following the transition, an acceleration of tapping was observed. In Experiment 2, participants were informed about the exact position of the transition, which was in addition marked by a pitch change. Nonetheless, the same acceleration occurred. Experiment 3 dissociated the actual from the expected position of the transition, without changing the results. In addition, the delay of the feedback tones was manipulated and was found to affect the rate of tapping in the continuation phase. A single delayed tone at the transition had no lasting effect, however. The results are interpreted in light of the synchronization-continuation model of Vorberg and Wing [Vorberg, D., & Wing, A. (1996). Modelling variability and dependence in timing. In H. Heuer, & S. W. Keele (Eds.), Handbook of perception and action, Vol. 2 (pp. 181-262). San Diego: Academic Press], with the added assumption that the synchronization tapping strategy is maintained in the continuation phase.     

A review of the H-reflex and M-wave in the human triceps surae

The soleus is the most commonly used muscle for H-reflex studies in humans, while limited comparable data have been produced from the gastrocnemii muscles. This article reviews the fundamental differences between the structure and function of the human soleus and gastrocnemii muscles, including recent data published about their complex innervation zones. Protocols for eliciting, recording, and assessing the H-reflex and M-wave magnitude in the human triceps surae are also discussed.     

Masculinity, Femininity, and the Bem Sex Role Inventory in Turkey

The aim of this study was to examine the masculinity and femininity scales of Bem Sex Role Inventory (BSRI) among Turkish university students. Five hundred thirty-six students (280 men and 256 women) volunteered to complete the short-form of the BSRI and answer demographic questions. In factor analyses, the original factor structure (Bem, 1981) was found both in the mens and womens data. Comparisons of the factor structures with target rotation (Procrustes rotation) and comparison indexes showed no difference between the factor structures found among men and women. The internal consistency of the masculinity and femininity scales was acceptable, and t-tests showed that women scored higher on the femininity scale, and men scored higher on the masculinity scale. There were significant differences between men and women only on two masculinity items, but significant differences were found in 8 (of 10) femininity items.     

Unique temporal change is the key to attentional capture

Abstract— Attentional capture refers to the observation that some events break through and attract one's attention even when one is engaged in a task for which these events are irrelevant. Previous research, focusing primarily on spatial factors, has shown that a new object is more salient in this regard than an abrupt change in an object's features. Here we show that feature changes can be as effective as new objects in capturing attention, provided that they occur during a period of temporal calm. Conversely, both feature changes and new objects are far less effective in capturing attention when they occur simultaneously with other display changes, such as coincident with the initial onset of the display or with small visual transients that occur during a display transition. These results highlight the importance of considering both space and time in studies of attentional capture; the most effective stimulus is unique in both dimensions.     

Determinants of stress-related growth: Gender,stressfulness of the event,and coping strategies

The present study aimed to investigate the determinants of stress-related growth. For this aim the associations of gender, stressfulness of the event, and three coping strategies (problem-oriented, fatalistic, and helplessness) with stress-related growth were tested by multiple regression analysis. Participants were 132 undergraduate students. Results revealed that females reported higher levels of stress-related growth than males, and as expected, higher levels of the stressfulness of the event associated with more stress-related growth. Furthermore, frequent utilization of problem-oriented and fatalistic coping strategies was associated with higher stress-related growth. These findings were discussed in the light of relevant literature and culture-specific features. This work has been supported by the Turkish Academy of Sciences, in the framework of the Young Scientist Award Program (TG-TUBA-GEB>P/2002-l-l 1).     

The visual-auditory color-word Stroop asymmetry and its time course

Four experiments examined crossmodal versions of the Stroop task in order (1) to look for Stroop asymmetries in color naming, spoken-word naming, and written-word naming and to evaluate the time course of these asymmetries, and (2) to compare these findings to current models of the Stroop effect. Participants named color patches while ignoring spoken color words presented with an onset varying from 300 msec before to 300 msec after the onset of the color (Experiment 1), or they named the spoken words and ignored the colors (Experiment 2). A secondary visual detection task assured that the participants looked at the colors in both tasks. Spoken color words yielded Stroop effects in color naming, but colors did not yield an effect in spoken-word naming at any stimulus onset asynchrony. This asymmetry in effects was obtained with equivalent color- and spoken-word-naming latencies. Written color words yielded a Stroop effect in naming spoken words (Experiment 3), and spoken color words yielded an effect in naming written words (Experiment 4). These results were interpreted as most consistent with an architectural account of the color-word Stroop asymmetry, in contrast with discriminability and pathway strength accounts.     

Personality dimensions across cultures

In order to generalize the dimensional structure of personality-relatively independent groups of covarying traits-across languages and cultures, a large number of cultures must be studied. Until recently only a few worldwide personality datasets have been available. The first large-scale studies indicate that the pattern of covariation between personality traits is universal and is relatively easily generalizable across languages and cultures. In contrast to the structure of personality, the comparison of the mean trait scores across cultures is much more problematic because cross-cultural differences turned out to be very small in their magnitude, about one-third of the magnitude of individual differences within culture. More integral (e.g., the similarity between personality profiles) or subtle (e.g., the disparity between positively and negatively worded items) measures can reveal more systematic relationships with relevant socioeconomic and geographic variables than the mean scores themselves. Relatively modest sizes of cross-cultural differences in the mean values may imply that a reasonable scalar equivalence can be achieved, and all individuals, irrespective of their language and culture, can be represented in a common metric.
