Who's to blame: Attributions regarding causality in spouse abuse

Spouse abuse is examined from the perspective of attribution theory. Aggressors are seen as attributing their violent behavior to external causes, whether by projecting their negative traits onto their spouses or by finding excuses which blame temporary environmental factors. In contrast, victims often attribute the abuse to defects within themselves or situational factors affecting their spouses. The attribution process seems affected by the frequency, intensity and duration of the abuse, with temporal factors playing an important role in the woman's internalizing style. Furthermore, inadequate early coping efforts play a powerful role in establishing cognitive-perceptual patterns that serve to perpetuate the abuse.     

Two- and 3-Year-Olds Know What Others Have and Have Not Heard

Recent studies have established that even infants can determine what others know based on previous visual experience. In the current study, we investigated whether 2- and 3-year-olds know what others know based on previous auditory experience. A child and an adult heard the sound of one object together, but only the child heard the sound of another (target) object. When later the sounds of both objects were played simultaneously, the adult reacted with surprise and excitement (“Oh, listen, what is that?”). In response, both 24- and 36-month-olds directed the adult's attention to the target more often than chance and more often than in a control condition in which the adult had heard neither sound. These results indicate that by 24 months of age, children's understanding of others' knowledge and ignorance is not limited to the visual domain but extends across perceptual domains.     

Three‐year‐olds express suspense when an agent approaches a scene with a false belief

Research on early false belief understanding has entirely relied on affect‐neutral measures such as judgments (standard tasks), attentional allocation (looking duration, preferential looking, anticipatory looking), or active intervention. We used a novel, affective measure to test whether preschoolers affectively anticipate another's misguided acts. In two experiments, 3‐year‐olds showed more expressions of suspense (by, e.g. brow furrowing or lip biting) when they saw an agent approach a scene with a false as opposed to a true belief (Experiment 1) or ignorance (Experiment 2). This shows that the children anticipated the agent's surprise and disappointment when encountering reality. The findings suggest that early implicit knowledge of false beliefs includes anticipations of the affective implications of erring. This vital dimension of beliefs should no longer be ignored in research on early theory of mind.     

Effects of the premenstrual syndrome on facial expressions of sadness

This study examined the relationship between PMS and emotion-related electromyographic facial activity at different phases of the menstrual cycle. Twenty-four women of reproductive age (12 with PMS, 12 controls) participated in two EMG sessions (T1 and T2) in which they were shown photographic images that can elicit various emotions (IAPS stimuli). T1 took place in the follicular phase, T2 in the luteal phase. The activity of the musculus depressor anguli oris ("depressor", expression of sadness) was measured. Depressor activity was compared to activity of musculus orbicularis oculi ("orbicularis"; expression of joy). ANOVA yielded a significant increase of the activity of the depressor at T2 in the PMS group. The PMS group showed more frequent depressor activity during the luteal than the follicular phase. Orbicularis activity did not change from T1 to T2. Conclusions: The PMS group experienced various visual stimuli in a more depressed way during the luteal phase.     

Moral judgments, emotions and the utilitarian brain

The investigation of the neural and cognitive mechanisms underlying the moral mind is of paramount importance for understanding complex human behaviors, from altruism to antisocial acts. A new study on patients with prefrontal damage provides key insights on the neurobiology of moral judgment and raises new questions on the mechanisms by which reason and emotion contribute to moral cognition.     

12- and 18-month-old infants follow gaze to spaces behind barriers

Infants follow the gaze direction of others from the middle of the first year of life. In attempting to determine how infants understand the looking behavior of adults, a number of recent studies have blocked the adult's line of sight in some way (e.g. with a blindfold or with a barrier). In contrast, in the current studies an adult looked behind a barrier which blocked the child's line of sight. Using two different control conditions and several different barrier types, 12- and 18-month-old infants locomoted a short distance in order to gain the proper viewing angle to follow an experimenter's gaze to locations behind barriers. These results demonstrate that, contra Butterworth, even 12-month-old infants can follow gaze to locations outside of their current field of view. They also add to growing evidence that 12-month-olds have some understanding of the looking behaviors of others as an act of seeing.     

How 14- and 18-month-olds know what others have experienced

Fourteen- and 18-month-old infants observed an adult experiencing each of 2 objects (experienced objects) and then leaving the room; the infant then played with a 3rd object while the adult was gone (unexperienced object). The adult interacted with the 2 experienced objects in 1 of 3 ways: by (a) sharing them with the infant in an episode of joint engagement, (b) actively manipulating and inspecting them on his or her own as the infant watched (individual engagement), or (c) looking at them from a distance as the infant played with them (onlooking). As evidenced in a selection task, infants of both ages knew which objects had been experienced by the adult in the joint engagement condition, only the 18-month-olds knew this in the individual engagement condition, and infants at neither age knew this in the onlooking condition. These results suggest that infants are 1st able to determine what adults know (have experienced) on the basis of their direct, triadic engagements with them.     

Basic number processing in children with specific learning disorders: Comorbidity of reading and mathematics disorders

As well as being the hallmark of mathematics disorders, deficits in number processing have also been reported for individuals with reading disorders. The aim of the present study was to investigate separately the components of numerical processing affected in reading and mathematical disorders within the framework of the Triple Code Model. Children with reading disorders (RD), mathematics disorders (MD), comorbid deficits (RD + MD), and typically developing children (TD) were tested on verbal, visual-verbal, and nonverbal number tasks. As expected, children with MD were impaired across a broad range of numerical tasks. In contrast, children with RD were impaired in (visual-)verbal number tasks but showed age-appropriate performance in nonverbal number skills, suggesting their impairments were domain specific and related to their reading difficulties. The comorbid group showed an additive profile of the impairments of the two single-deficit groups. Performance in speeded verbal number tasks was related to rapid automatized naming, a measure of visual-verbal access in the RD but not in the MD group. The results indicate that deficits in number skills are due to different underlying cognitive deficits in children with RD compared to children with MD: a phonological deficit in RD and a deficit in processing numerosities in MD.     

The influence of attachment and temperament on venipuncture distress in 14-month-old infants: the Generation R Study

Objective

This study examined the effects of attachment and temperament on infant distress during venipuncture.

Method

The study was embedded in the Generation R Study, a prospective population-based study. Two different research procedures (i.e., blood sampling and the Ainsworth Strange Situation Procedure) yielded measures of venipuncture distress and attachment security and disorganization in 246 infants aged 14 months. Four temperament traits (distress to limitations, fear, recovery from distress, and sadness) were assessed using the maternally reported Infant Behavior Questionnaire - Revised, at the age of 6 months.

Results

There were no differences between mean levels of distress during venipuncture in infants classified as having insecure attachment, but there was a trend for disorganized attachment. The temperament traits were not related to distress. However, children with a disorganized attachment and higher temperamental fear had more venipuncture distress.

Conclusion

When different risk factors are present simultaneously, infant distress is heightened.     

Transcranial magnetic stimulation in child psychiatry: disturbed motor system excitability in hypermotoric syndromes

Normal development and dysfunctions of motor system excitability can be investigated in vivo by means of single‐ and paired‐pulse transcranial magnetic stimulation (TMS). While different TMS‐parameters show different developmental time courses between 8 and 16 years of age, distinct dysfunctional patterns of motor system excitability can be demonstrated in child psychiatric disorders with hypermotoric behavior: in tic disorder, a shortened cortical silent period can be stated providing evidence for deficient inhibitory mechanisms within the sensorimotor loop, probably primarily at the level of the basal ganglia. In attention deficit hyperactivity disorder (ADHD), a decreased intracortical inhibition indicates deficient inhibitory mechanisms within the motor cortex (but enhancement of intracortical inhibition after oral intake of 10 mg methylphenidate). In children with comorbid ADHD and tic disorder, the findings of a reduced intracortical inhibition as well as a shortened cortical silent period provide evidence for additive effects at the level of motor system excitability. Thus, TMS allows us to obtain substantial insight into both the normal development and the neurobiological basis of hypermotoric syndromes in child psychiatry.
