Handedness and drawing: attempting to complete the picture: a comment on Bruckner, et al. (2011)

In a recent study, Bruckner, Kastner-Koller, Deimann, and Voracek (2011) investigated the relationship between hand preference and drawing during preschool years. The present study offers interpretations in a larger framework which could contribute to the better understanding of that relationship, and provides future directions in this area.     

Change in dexterity with sensory awareness training: a randomised controlled trial

The role of sensory awareness in movement control is receiving increasing interest in sports and clinical literature as a feed-forward and feedback mechanism. The aim of the study was to assess the feasibility and effect of training in sensory awareness on dexterity in healthy adults. 29 healthy students were randomly allocated to a single-group, sensory awareness lesson with the dominant hand, the same lesson with the nondominant hand, or to a sham control group. Dexterity measures included the Purdue Pegboard Test, a grip-lift manipulandum, and perceived changes using a questionnaire. The sensory awareness lesson with the dominant hand produced a statistically significant improvement in mean dexterity compared to the control group, but not between the other two pairs of groups. The sensory awareness training paradigm is feasible and a single session improved dexterity in healthy adults.     

Cognitive parameters and morning and evening types: two decades of research (1990-2009)

An important area of study has examined cognitive aspects of morningness-eveningness orientation. Optimal times of efficiency in participants classified as Morning and Evening types are of great importance for understanding their cognitive abilities. The present review covers the last two decades (1990-2009), during which the important review by Tankova, Adan, and Buela-Casal appeared, and focuses particularly on attention, memory, and executive functions.     

Frequency drives lexical access in reading but not in speaking: the frequency-lag hypothesis

To contrast mechanisms of lexical access in production versus comprehension we compared the effects of word frequency (high, low), context (none, low constraint, high constraint), and level of English proficiency (monolingual, Spanish-English bilingual, Dutch-English bilingual) on picture naming, lexical decision, and eye fixation times. Semantic constraint effects were larger in production than in reading. Frequency effects were larger in production than in reading without constraining context but larger in reading than in production with constraining context. Bilingual disadvantages were modulated by frequency in production but not in eye fixation times, were not smaller in low-constraint contexts, and were reduced by high-constraint contexts only in production and only at the lowest level of English proficiency. These results challenge existing accounts of bilingual disadvantages and reveal fundamentally different processes during lexical access across modalities, entailing a primarily semantically driven search in production but a frequency-driven search in comprehension. The apparently more interactive process in production than comprehension could simply reflect a greater number of frequency-sensitive processing stages in production.     

Methodological implications of the affect revolution: a 35-year review of emotion regulation assessment in children

This investigation analyzed the methods used over the past 35 years to study emotion regulation (ER) in children. Articles published from 1975 through 2010 were identified in 42 child clinical, developmental, and emotion psychology journals. Overall, 61.1% of published ER articles relied on one method and 23.6% used two methods. Analyses revealed (a) 82.8% of published ER research occurring within the past decade; (b) higher rates of observational methods with infant and toddler/preschool samples, but more use of self-report methodology with middle childhood and adolescent samples; (c) a longer history of published ER research with samples of infants to 5-year-olds, including the use of more longitudinal design, compared with older samples; and (d) a positive association between journal impact ratings and the use of physiological and observational measurement. Review of the measurement tools used to capture ER revealed great diversity in how emotion processes are understood and evaluated.     

The shape of action

How do people understand the everyday, yet intricate, behaviors that unfold around them? In the present research, we explored this by presenting viewers with self-paced slideshows of everyday activities and recording looking times, subjective segmentation (breakpoints) into action units, and slide-to-slide physical change. A detailed comparison of the joint time courses of these variables showed that looking time and physical change were locally maximal at breakpoints and greater for higher level action units than for lower level units. Even when slideshows were scrambled, breakpoints were regarded longer and were more physically different from ordinary moments, showing that breakpoints are distinct even out of context. Breakpoints are bridges: from one action to another, from one level to another, and from perception to conception.     

"Princess Alice is watching you": children's belief in an invisible person inhibits cheating

Two child groups (5-6 and 8-9 years of age) participated in a challenging rule-following task while they were (a) told that they were in the presence of a watchful invisible person (“Princess Alice”), (b) observed by a real adult, or (c) unsupervised. Children were covertly videotaped performing the task in the experimenter’s absence. Older children had an easier time at following the rules but engaged in equal levels of purposeful cheating as the younger children. Importantly, children’s expressed belief in the invisible person significantly determined their cheating latency, and this was true even after controlling for individual differences in temperament. When “skeptical” children were omitted from the analysis, the inhibitory effects of being told about Princess Alice were equivalent to having a real adult present. Furthermore, skeptical children cheated only after having first behaviorally disconfirmed the “presence” of Princess Alice. The findings suggest that children’s belief in a watchful invisible person tends to deter cheating.     

Reliability of self-reported attachment style in patients with severe psychopathology

Little is known about whether severe psychopathology influences the assessment of self-reported attachment style. Fifty-eight randomly selected adult psychiatric inpatients completed the Experiences in Close Relationship questionnaire (ECR; Brennan, Clark, & Shaver, 1998) and were administered the 24-item Brief Psychiatric Rating Scale (BPRS; Ventura et al., 1993) and the Hamilton Depression Rating Scale (HDRS; Hamilton, 1960) at both admission and discharge. The Structured Clinical Interview for DSM-IV (SCID-I; First, Spitzer, Gibbon, & Williams, 1996) was used to establish Axis I diagnoses. The ECR scales showed good internal consistency and absolute stability both in patients with (n = 24) and without (n = 34) a psychotic disorder. Relative stability was only fair among patients with psychotic disorders but good among patients without psychotic disorders. Neither higher BPRS or HDRS scores, nor the presence of a psychotic disorder, significantly reduced the retest reliability of the ECR scales. These findings suggest that self-report measures might provide a reliable assessment of attachment style in patients with severe psychopathology, except for the most severely impaired patients.
